Description

Energy generation system, motor vehicle

and generator comprising such a system

Technical field and state of the art

The present invention relates to a system for generating energy.

More particularly, the present invention relates to the admission of hydrogen and oxygen to the air mixture of a heat engine fueled by fuel.

Hydrogen engines are known. The disadvantage of this type of hydrogen engine is the risk of explosion, leakage because the engine is under pressure. In addition, these hydrogen engines are very complicated to manufacture because the pressure is important.

There are also fuel cells that use rare materials and are very expensive. Fuel cell technology uses reservoirs that store hydrogen at high pressure such as 700 bar. Such storage on a vehicle endangers the passengers of the vehicle and the people around up to ten meters. In addition, it is necessary to have electrical energy to make such a pressure vessel so that the carbon footprint of the use of fuel cells is not profitable.

Another disadvantage is the weight of such technology; typically the vehicle weighs 40% more than a conventional vehicle. However, for a vehicle launched at 90km / h, its consumption is almost proportional to its weight.

A solution is presented in WO2007 / 133174; this document describes a generation of hydrogen and oxygen. This system cleans the engine and reduces pollutants by cleaning the engine. The reduction of the fuel is related to the cleaning of the engine induced by the admission of hydrogen vapor and oxygen in the intake of the engine. The disadvantage of this type of system is that the production depends on a battery and that this production is then very low. Another disadvantage is that the engine electronics are not designed to work with such a system. This vaporization can therefore not be properly taken into account in reducing the fuel intake.

The purpose of the present invention is to provide an energy generation system for improving the creation of hydrogen and oxygen to reduce fuel consumption a thermal engine while reducing the risks associated with the storage of hydrogen and oxygen.

Preferably, the heat exchanger consists of a plate heat exchanger or a tube heat exchanger.

Also preferably, the energy generating system comprises the means for cooling the first generator or second generator to lower the operating temperature.

The cooling means makes it possible to maintain a temperature of less than 100 ° so as to avoid the drop in the generation of the magnetic field and to ensure the proper functioning of the generator without any degradation.

In addition, the cooling means does not prevent transferring the heat dissipated to a fluid in order to transfer said heat to a heat transfer oil. The goal is to recover the heat and not to dissipate it. It can be used any means of heat recovery. In one aspect, the power generation system includes a cooling means of the electrolyzer for lowering the operating temperature.

The cooling means makes it possible to maintain a temperature of less than 100 ° in order to ensure the good performance of the electrolyser.

In another aspect, said first generatrix or second generator comprises at least one rotor consisting of several permanent magnets and a magnet holding device to ensure the proper maintenance of the position of the magnets.

During operation, the speed of rotation is high, the locking means can encapsulate the magnets to prevent damage to the system.

Also in another aspect, the cooling means comprises a circuit of a fluid passing through the generator and an exchanger for cooling the fluid. For example, the fluid is water.

Description of Embodiments of the Invention

The principle is to transform water into hydrogen and oxygen by an electrolyser powered by the generator. The use of hydrogen and oxygen makes it possible to reduce, on the one hand, pollution by reducing, for example, CO ₂ particles and, on the other hand, the consumption of the engine. A mixture of hydrogen and oxygen reduces between 50 and 95% of the fuel consumption compared to its injection without mixing hydrogen and oxygen.

Figure 1 illustrates the operating principle of the invention.

The energy generation system comprises a heat engine 1, a first generator 3, a second generator 3, an electrolyzer 7, a tank 9 of electrolytic liquid and a heat exchanger 15. It is possible to have an operation with water or demineralised water. The energy generation system also comprises at least one means for cooling the generator and the electrolyzer, a means for filtering the gas produced by the electrolyser 7 and a means for regulating the injection time 11.

A heat exchanger 15 feeds at least one turbine 14. The turbine 14 produces a rotational energy. A first generator 3 is directly connected to at least one turbine 14 for the purpose that the turbine rotates the first generator 3. For example, for two second generators 3, it is preferable to have four turbines 14. The second generator 3 current feeds an electrolyzer 7 which will be detailed below.

The heat exchanger 15 has a refrigerant circuit, a heat-carrier oil circuit, a refrigerant inlet 151 and a refrigerant outlet 152, a heat-carrier oil inlet 153, and a heat-carrier oil outlet 154. For example, the refrigerant is a l, 1, 1, 2-tetrafluoroethane (CH ₂ F-CF ₃ ) water or any type of fluid passing from a liquid state to a gaseous state. Heat transfer oil is a synthetic oil for heat transfer.

The refrigerant 151 is stored in a refrigerant tank 16, for example the tank is a coolant liquid balloon and the fluid has an evaporation temperature of the order of 80 to 150 ° C. The refrigerant enters the heat exchanger 15 through the refrigerant inlet 151, for example the fluid is at room temperature. The refrigerant changes from liquid to gas. For example, the heat exchanger 15 is a plate heat exchanger. The refrigerant circuit operates on the principle of the thermodynamic cycle.

The refrigerant at the refrigerant outlet 152 of the heat exchanger 15 is at high temperature and in the form of a gas. The high-pressure gas makes it possible to turn turbines 14. At the outlet of the turbine 14, the gas enters a cooling means 31, for example the cooling means 31 is a condenser or exchanger so as to cool the gas so that it passes in the form of liquid. At the outlet of the cooling means, a liquid is obtained which has, for example, a temperature of 30 ° C. This fluid is then conveyed to the refrigerant reservoir 16.

A pump 8 circulates the refrigerant. The refrigerant operates at high pressure and the pump 8 must be provided to withstand this pressure. For example, the pump 8 is located between the refrigerant reservoir 16 and the heat exchanger 15.

The heat exchanger 15 has the function of recovering the thermal energy from the engine or more generally from a heat source (for example, exhaust gas, electrolyser, etc.). This heat source can be recovered from the power generation system (such as the exhaust gas from a heat engine, the electrolytic liquid from the electrolyser), or recovered from another system that has thermal energy. . The heat exchanger 15 also has a heat-transfer oil inlet 153. When the heat-transfer oil is admitted inside the exchanger 15, the heat-transfer oil is at a high temperature, for example 150 ° C. . The heat exchanger makes it possible to give the heat calories to the refrigerant. At the heat-transfer oil outlet 154, the heat-transfer oil is at a low temperature, for example 30 ° C. The heat exchanger makes it possible to have an exchange between the refrigerant circuit and the heat transfer oil circuit.

The heat-transfer oil at low temperature enters a cooling means 31 and allows the electrolytic liquid supplying the two electrolysers 7 to be cooled. 3 1 cooling, the heat transfer oil is always at low temperature and will be routed to another cooling means 31 so as to recover the heat of the refrigerant which changes from the gas state to the liquid state. The heat transfer oil will be warmer at the outlet of the cooling means 31, for example the heat transfer oil will have increased in temperature and may be at 50 ° C. The heat transfer oil is then conveyed to the first generator and / or the second generatrix, or to the turbine or turbines 14. The purpose is to cool the first generator 3, or the second generator 3 or the turbines 14 and to also allow to recover a portion of the heat generated by the first generatrix 3, and / or the second generator 3 and / or the turbines 14. The heat transfer oil will be warmer after this passage, for example 70 ° C. To further gain heat, the heat transfer oil passes through the engine 1 and will stand out at 90 ° C for example. The heat transfer oil is then conveyed to the exhaust to recover the heat of the explosion. For example, this exchange is carried out by a tube exchanger. The heat transfer oil at the outlet of the tube exchanger is at a high temperature, for example 150 ° C., and enters the heat exchanger 15. In this way, the heat generated by the various elements of the heat exchanger system is recovered. energy generation so as to use a maximum of heat. For example, the heat exchanger recovers thermal heat from the exhaust gas, the electrolyser and / or any other heat source. In addition, the system as described recuperates the heat little by little which avoids having a significant temperature difference between a heat transfer oil inlet in an element and the sotrie this element. For example, it is avoided to go from 30 ° C to 150 ° C at one time. It is then possible to have several heat exchangers 15 to recover heat little by little.

The heat engine 1 produces rotational energy. Via a belt 2, a second generator 3 is rotated according to the engine speed. The second generator 3, which we will detail below, creates electrical energy. The second generator 3 is composed of a rotor consisting of several permanent magnets and a stator consisting of a winding of copper wire. The second generator 3 creates a three-phase electricity by its configuration.

The second generator 3 is connected to a diode bridge for rectifying the AC direct current. It is also possible for the generator to be connected to a diode bridge to rectify the pulsed current or as a simple rectification.

The direct current coming from the first generatrix 3 or the second generatrix 3 feeds two electrolysers 7 which make it possible to carry out chemical reactions of an electrolytic liquid using direct current. These two electrolysers 7 are identical and consist of several electrodes; they will be detailed below. A regulation means of the voltage of 6 of each electrode prevents overheating of the electrolyzer and ensures the good performance of the electrolysis. In fact, overheating considerably reduces the efficiency of the electrolysis.

The regulating means of the voltage 6 of each electrode is an automaton. The automaton comprises means for measuring the voltage of the first generator or the second generator 3. The voltage measuring means 5 may also perform a measurement at the output of the diode bridge 4. The measurement information is transmitted to the controller that provides the power supply function of the electrolyser 7 to ensure a voltage between 1.75 and 2.5V per electrode. Voltage should be limited to 2.5V to prevent overheating. To ensure proper operation, the temperature is below 60 ° C. The automaton acts on static relays of 200A so as to distribute the power supply without ever exceeding 2.5V per electrode. For example, for twenty electrodes, the overall voltage will not exceed 40V.

When the reservoir 9 contains water or demineralised water, the power supply function of the automaton to regulate the electrolyser will ensure a voltage of 1.75 to 20V per electrode. Alternatively, the regulating means 6 is not useful when the generator uses a voltage regulator.

At the outlet of the electrolyser 7, a gas consisting of a mixture of oxygen and hydrogen is created. This gas is cleaned by gas filtration means to clean the mixture. The gas is created using the electrolytic liquid potassium or other type, such as sodium. It is necessary to use the gas filtration means for two functions: as flame arrestor and as gas cleaning to extract the electrolyte liquid from the mixture of hydrogen and oxygen.

The gas passes through a flow sensor 10. The flow sensor makes it possible to regulate the flow rate of the fuel to be conveyed to the heat engine 1. The information of the flow sensor 10 is sent to the injection timing control means 1 1 fuel. The flow rate of the fuel is then regulated by the means for regulating the injection time 1 1 of the fuel in order to adjust the needs of the heat engine 1 to fuel. The gas passes through a nonreturn valve 13 to protect the system from possible backfires in the pipe. Preferably, the nonreturn valve 13 is close to the combustion chamber of the heat engine 1. The gas is then mixed with air to be introduced into the combustion chamber of the heat engine 1. In order to optimize the injection time of the heat engine 1, the present invention has a means for regulating the injection time 11. Said means for regulating the time injection 1 1 optimizes the intake of gas produced with the fuel to reduce fuel consumption. For example, the fuel injection time is reduced by 80%.

Inside the heat engine 1, a specific oil is replaced so that the admission of a gas consisting of a mixture of hydrogen and oxygen is optimum. For example, the specific oil is used to operate with hydrogen, such as ceramic oil. If the installation of the present invention is to be carried out on an already existing heat engine, draining may be necessary in order to replace the existing oil.

The heat engine 1 is connected to an exhaust 12.

Figures 2 and 4 illustrate the generator 3. For the rest, the first generator 3 or the second generator 3 will be called generator 3.

The generator 3 has a cooling means 31, not shown in Figure 2 or 4, to lower the operating temperature. During its operation, the generator 3 rotates at high speed which causes a heating of the various parts. For example, the cooling means 31 of the generator 3 is formed by the passage of a circuit of a fluid inside the generator 3, such as heat transfer oil as mentioned above.

According to a variant, it can be provided that the cooling means is also made by air or that the cooling means 31 is a radiator or a heat exchanger. In FIG. 2, the inlet of the cooling liquid 32 is shown. the coolant outlet 33. The generator 3 creates a three-phase electricity and three-phase electrical outputs 34 are shown.

Generator 3 has a speed multiplier. For example, the generator has a pulley 312 that multiplies the rotational speed of the engine by four. According to one variant, the generator 3 is connected directly to a turbine 14 without a speed multiplier.

The generator 3 has a rotor consisting of magnets 309. For example, the magnets 309 are rare earth neodymium such as N42 or rare earth in general, or ferrites, alnico, neodymium, cobalt. These magnets 309 are nested in an interlocking part of the magnets 308 in order to maintain these magnets 309 in their position relative to each other during operation. A metal disk 307 is on either side of the interlocking part of the magnets 308. A magnet holding device consists of two metal disks 307 and the interlocking part of the magnets 308 and magnets 309. metal discs 307 may be in another material, such as composite. Inside the generator 3, a fluid is used, preferably a dielectric liquid to ensure the dissipation of heat and therefore a cooling of the generator 3. It can also be used a heat transfer oil as mentioned above. The various rotating parts are fixed to the rotating shaft 310 by means of one or more nuts 31 1. The rotating shaft is held in position by bearings 302. It can be added a seal 305 which can to be lip to prevent leakage of the dielectric fluid of the generator 3. The set of parts is surrounded by metal parts having a passage for the coolant 313. Between each metal part, two O-rings 304 ensure the sealing between these metal parts. Two flanges 306 are on either side of the generator 3 and encapsulate all the metal parts. The set of metal parts is integrally fixed by studs 301.

Around the rotor is positioned a stator 303 consisting of a number of winding copper wire. For example, the stator 303 has two copper wires of diameter 1, 2mm which are doubled and their length depends on the number of desired phases. FIG. 4 represents two rotors and two stators 303. This generator 3 makes it possible to provide

15 W by a thermal engine of OOcv. It may be considered to increase or reduce the number of rotor and stator to meet the desired need. The rotor and the stator 303 are arranged at a distance of the order of 0, 1 and 2 mm. The distance is the distance between the rotor and the stator. For example, the rotor and the stator are arranged at 0.5 mm distance. Too small a gap can cause system degradation if the rotor touches the stator. When the rotor is too far, for example beyond 2 mm, the power of the system is greatly reduced.

In FIGS. 3 and 5, the electrolyser 7 has an inlet 71 of an electrolytic liquid. At the outlet of the electrolyser 7, a mixture of gas and liquid is created and passes through the outlet of the gas 72. A pump 8 supplies the electrolyzer 7 with the electrolytic liquid contained in the tank 9.

This pump 8 makes it possible, on the one hand, to circulate the electrolytic liquid and, on the other hand, serves as an anti-return flow of the liquid in the reservoir.

The electrolyser also has a cooling means 31 which makes it possible to lower the temperature of the electrolytic liquid. Indeed, at the output of the electrolyser, the electrolytic liquid has warmed up and to ensure proper operation under the same conditions, it is preferable to lower the operating temperature by the cooling means. For example, the cooling means is a plate heat exchanger. A pump 8 feeds the plate heat exchanger. This pump 8 serves to circulate a cold liquid from the cooling means to the plate heat exchanger to cool the electrolyte liquid passing through the plate heat exchanger. There is no mixing between the electrolytic liquid and the cold liquid of the cooling means. The electrolyser 7 consists of a plurality of electrodes. Each electrode may be anode or cathode electrode 703 or a neutral electrode 704. For example, the anode or cathode electrodes 703 or the neutral electrodes 704 are made of 316L stainless steel or polymer.

Each anode electrode or cathode 703 has a bore for a liquid passage 705, a bore for the passage of gas 707 and a terminal 706 connectable to a positive or negative current. In order to improve the circulation in the passage bores of the gas 707, the passage of the gas 707 is reversed from one neutral electrode 704 to the other. The electrolyser also has neutral electrodes 704. These neutral electrodes 704 also have a bore of the liquid passage 705 and a gas passage bore 707. The bore of the liquid passage 705 circulates the electrolytic liquid through the channels. Different electrodes anodes or cathodes 703. The electrolyzer 7 has sealing means between each anode electrode or cathode 703 and neutral electrode 704. These sealing means make it possible to ensure the seal between the anode electrodes or cathodes 703 and the neutral electrodes 704 to prevent leakage of the electrolytic liquid. For example, the sealing means is a seal 702 which is positioned between each neutral electrode 704 and each anode or cathode electrode 703. The seal 702 also provides electrical isolation between the anodes or cathodes 703 or 703. the neutral electrodes 704. The electrolyzer 7 is closed by a cover 701 located on either side of the various elements of the electrolyser 7. The cover 701 makes it possible to contain the electrolytic liquid inside the electrolyser 7.

A seal 702 is positioned on each side of the cover 701 to provide overall sealing of the electrolyser 7. Each of the neutral electrodes 704, anode electrodes or cathodes 703, seals 702 have bores. to allow their attachment and ensure sufficient space to allow the chemical reaction. This space is of the order of 0.5 mm to 20 mm according to the amperage and can be achieved by the thickness of the seal 702 or by any other insulating means. In this way, this space makes it possible to be optimum for the chemical reaction of the electrolytic liquid and ensures a good yield of the electrolyser 7. In the embodiment presented, the space between each anode electrode or cathode 703 and each neutral electrode 704 is 3 mm.

In order to maintain and position the anode or cathode electrodes 703 and the neutral electrodes 704, rods are inserted through the different parts of the the electrolyser 7. Other types of maintenance of the anode or cathode electrodes 703, neutral electrodes 704 and covers 701 may be envisaged, for example lugs on anode or cathode electrodes 703 and bores crossing or not the neutral electrodes. 704.

A first anode or cathode electrode 703 is positioned on one side of the electrolyser 7. This first anode or cathode electrode 703 is connected to the negative terminal which will therefore be the cathode. Then, a plurality of neutral electrodes 704 is positioned and finally an anode electrode or cathode 703 is connected to the positive terminal which will be the anode.

The anode or cathode electrodes 703 and the neutral electrodes 704 have a thickness of the order of 0.1 to 3 mm. For example, the anode or cathode electrodes 703 and the neutral electrodes 704 have a thickness of 1 mm.

FIGS. 6 and 7 represent the reservoir 9. In the embodiment described, the reservoir 9 also has a means for filtering the gas created by the electrolyser 7. The reservoir 9 comprises an access to the reservoir 91 in order to fill the reservoir. an electrolytic liquid, and an outlet of the liquid 92 for supplying the electrolytic liquid to the electrolyzer 7. The reservoir 9 also comprises a gas inlet 93 and an outlet of the gas 94.

The reservoir 9 comprises partitions 901 to prevent the liquid from moving. These partitions 901 are not sealed relative to each other, the electrolyte liquid is distributed throughout the tank to have the same level in the tank. The minimum level of electrolytic liquid corresponds to the level of the bubbler 902. The maximum level of the electrolytic liquid is limited by access to the tank 91 so that the electrolytic liquid is not conveyed with the gas into the engine inlet.

Hydrogen and oxygen and a part of the electrolytic liquid pass through the inlet of the gas 73 and arrive in a bubbler 902. The bubbles created by the bubbler pass through a baffle network to clean the product gas, the electrolyte liquid remains in the tank 9 to then go back to the electrolyser. The arrow F represents the path of the bubbles created by the bubbler 902.

The proportion of the gas is 1 volume of oxygen and 2 volumes of hydrogen.

Figure 8 shows an example of operation of the invention for a generator. The heat engine 1 is a turbo diesel engine V8 comprising a turbo. The generator set of 200kW / h produces a three-phase alternating current. The energy generation system makes it possible to recover the heat of the heat engine 1 (of the order of 90 °) and of the exhaust gases (of the order of 450 °). The exhaust gas passes through a heat exchanger, called evaporator 17. For example, the exhaust gas is between 450 and 300 ° and can heat the refrigerant 100 ° to 150 ° output. Then, the exhaust gas is discharged through the exhaust outlet 121. The diagram indicates several heat exchangers to increase the heat of the refrigerant little by little. On leaving the evaporator 17, the refrigerant (of the order of 150 °) passes through a turbine 14 which rotates a generator 3. The generator 3 supplies the electrolyser 7. It is possible or not to have a voltage regulating means 6. The system comprises a circuit (closed) of a refrigerant which passes through a condenser 19, three heat exchangers, a regenerator 18 and an evaporator 17. The circulation of the refrigerant is ensured by a circulation pump 8.

At the outlet of the turbine 14, the refrigerant enters another heat exchanger, called regenerator 18. It makes it possible to increase the temperature of a portion of the refrigerant circuit so as to raise its temperature from 90 ° to 1 ° C. About 10 °. The refrigerant, at the inlet of the regenerator 18, is at a temperature of about 90 ° and comes from three heat exchangers. These three heat exchangers allow the refrigerant to go from a temperature of 30 ° (about) to a temperature below 60 °, then to go from a temperature of 60 ° (about) to a temperature below 80 ° and to pass from a temperature of 80 ° (about) to a temperature of less than 90 °. The refrigerant, at a temperature of 30 ° (approximately), comes from another heat exchanger, called condenser 19.

One of the three heat exchangers heats the refrigerant by the coolant of the engine 1 which is at a temperature below 90 ° (otherwise the engine is safe). A pump 8 circulates the coolant in a closed circuit.

Another of the three heat exchangers heats the refrigerant by the electrolytic liquid of the electrolyzer 7 which is at a temperature below 80 ° (to ensure the proper functioning of the electrolyser). A pump 8 makes it possible to circulate the electrolytic liquid in a closed circuit. In this example, the thermal heat loss of an electrolyser is 50%, the heat exchanger makes it possible to recover 25% of the 50% of the heat loss.

The last of the three heat exchangers heats the refrigerant by the compressed air of the turbo engine 1 which is at a temperature below 60 °. The circuit of the compressed air comes from the turbo and passes through a heat exchanger and arrives in the intake of the engine 1. The condenser 19 heats the refrigerant by an exchanger or a cooling tower 21. The cooling tower 21 comprises a closed circuit which passes through the condenser 19. A pump 8 circulates the water in the condenser 19 before returning to the tower A temperature sensor or sensor 20 measures the water circulation temperature and gives the information to the pump 8 so as to more or less speed up the flow of water between the cooling tower 21 and the condenser 19.

A temperature sensor 20 measures the inlet temperature of the turbine 14 so as to more or less accelerate the flow rate of the circulation pump 8 of the refrigerant circuit. The temperature sensor 20 transmits the information to a regulating means of the pump 23 to more or less act on the control of the circulation pump 8 in order to adapt the flow rate in the circuit of the refrigerant.

The electrolyser 7 creates a gas consisting of a mixture of oxygen and hydrogen. This gas is cleaned by gas filtration means 22 to clean the mixture. Then, the gas passes through a check valve 13 to then be inserted into the inlet of the engine 1.

In another variant, it may be envisaged, without departing from the scope of the invention, to adapt the proportions, the forms of the energy generation system, the generator 3, the electrolyser 7 and those of the reservoir 9 such as those described above by simple constructive provisions that will appear directly and without undue effort to the skilled person.
