According to the general device of first scheme that is used to implement apparatus of the present invention as shown in Figure 1.The longitudinal section of blender 1 shown in Figure 2, Fig. 3 are the top sectional elevations on blender 1 plane that contains the hole.At first referring to figs. 2 and 3 describing blender 1.

Blender 1 comprises a garden cylinder outer race, and its end 10 opens wide, the other end 11 sealings.In the tube of garden, hollow component 13 comprises first 14 and the second portion 17 that has the ring 12 that links to each other with its centre.The first 14 of element 13 has the basic hollow parabolic shape that is, it is in the ring 12 and the sealing chamber between the blind end 11 of blender 1.In a preferred embodiment, first 14 has complete hollow parabolic shape.First 14 tops (about in an embodiment 1/3) in a preferred embodiment has several holes 15 of passing element 13 walls, and the direction in hole 15 is tangential.Pipe 16 is stretched with respect to the axis of blender slightly obliquely from the blind end of blender 1.Element 13 also is included in the second portion 17 that place, ring 12 planes links to each other with first 14.This part is taper basically, and its extension is a short garden column jecket 18.In a preferred embodiment, the 17th, hyperbola.Blender 1 is a glassware, and fluid components flows to first 14 rotatably by inclined tube 16, in first, most of fluid components of introducing hole 15 is flowed (downward in Fig. 2) to the top along first's 14 inwalls, is further rotated simultaneously.Fluid turns back at the top, and its speed raises gradually, towards the central axis place formation eddy current of second portion; By this eddy current mixing different material.

During work, introduce the liquid mixture of forming by hydrophobic liquid phase and hydrophilic liquid phase by inlet tube 16.Since inlet tube 16 from axle and oblique layout, the fluid of introducing will rotate around the central axis of blender 1; Rotating fluid enters by the oblique hole 15 on the wall of the first Room part 14.The first Room part has the commentaries on classics of n rank and revolves the paraboloid shape, and minimum place forms focal line at pressure, and the Way out towards opening wide reduces in the axial direction along axial pressure.Here refer on radial and axial, pressure little by little reduces.Fluid ring rotates and along axial flow around axis.

At the second Room part conical section 17, raise gradually towards the flowing velocity and the rotary speed of exit portion 18, axis reduces to internal pressure in the radial direction upper edge, reaches minimum along axis.The preferred 17 sections rotation hyperbolic body function and the paraboloid function of the first Room part have identical exponent number.

The stream shape had of flowing can estimate, its style seem fluid mass by unlimited a plurality of have substantially form according to the annular hollow pipe of tapering part 17 shapes.The rotary speed difference of each pipe just makes single pipe change each other when they rotatablely move.Yet single pipe changes the rotary speed difference that not only is them each other, and their motion and changing also all on axis direction.

From this stream shape figure, can be clear that, can imagine that the phase boundary contact-making surface is great.Simultaneously, because shear action between single pipe, will not carry out very effective contact between on the same group at mixture.Be positioned at central axis place pressure minimum, the component that density is lower will be tending towards concentrating at the axis place of contiguous maximal rate.This just guarantees that the fine particle that obtains in the zone of action can not escape.

Phase transformation (as, arbitrary component vaporization) can not take place should to regulate flow velocity.However, minimum pressure must be just on the vapour pressure of liquid mixture.Because of containing several liquid, should have such condition, promptly have the highest vapour pressure under the fixed temperature.This condition is equivalent to a kind of like this state, promptly can not produce cavitation in flowing.Blender preferred glass goods.Can reach and regulate above-mentioned state till in pipe 18, minute bubbles occurring by improving flow stream velocity.Therefore, less flow stream velocity just in time is the values of minute bubbles when disappearing once more.

Now, with reference to figure 1 first kind of scheme described.In blender 1, closed loop comprises pump 2 and container 3, is interconnected to form by pipeline 4,5,6,7.The outlet of mixture is discharged in label 8 representatives, and it has a cock; Only it is just opened when discharging mixture.Container 3 has pipe 31 usefulness cocks and pipe 32 usefulness cocks to be used for injecting initial material to form mixture.Fluid flows as shown by arrows.

Describe now and how do not add emulsifying agent and hydrophobic liquid is caused prepare stable water/hydrophobic liquid mixture in the water with the device shown in Fig. 1～3.

At first, open the cock of pipeline 31, in container 3, inject distilled water 91.Then open cock 32, in container 3, inject oleovitamin A 11 as initial oil.Blanked-off pipe 31 and 32 cock.It may be noted that container 3 fully water and oleovitamin A be full of, also can make container top empty.

Start pump with this set.Pump discharge is 25l/min.The about 14mm of internal diameter of pipe 4,5,6,7.The liquid flow path direction is shown in Fig. 1 arrow.Water and oleovitamin A are introduced blender 1.In blender 1, water and oleovitamin A flow in the barrel of garden rotatably from inclined tube 16, flow into first 14 by tangential hole 15, form eddy current in hollow member 13.Describe in more detail now.Most of rotating fluid component flows to the paraboloid top of sealing first and turns back therefrom.Because being the taper of index law, the shape of hollow member 13 second portions 17 diminishes gradually.Fluid components is with other component rotation promptly together, and fluid components is pushed to container 3 in pipe 5.Therefore, fluid components circulates in sealing system stream and stops up to pump 2.After water and oleovitamin A mixture stopped to flow, cock was opened, and water/oleovitamin A mixture is discharged from outlet 8.

One example is described now.Mix with hydrophobic liquid with the hydrophilic liquid of mixing arrangement shown in Figure 1 in this example.Open pipe 31 cocks, 91 ethanol are injected container 3, then open pipe 32 cocks the 1l vitamin A is injected container 3.Program afterwards as mentioned above.The mixture for preparing 9l oleovitamin A and 1l ethanol as stated above equally.Mixed ethanol and oleovitamin A and need not add emulsifying agent and can obtain its mixture according to the method described above.This method can be widely used in produces moisturizing lotion and soothing oil.

Describe the example of second kind of scheme of the present invention in detail referring now to Fig. 4.Indicate and the first scheme same section with identical code name.The alternative plan and the first scheme difference are to replace mixing arrangement 3 to form second eddy current with container 9.Container 9 has a top 91 that is garden shape basically, and bottom 93 is tapered downwards, and mid portion 92 gardens connect shape top 91, garden and bottom 93 slidingly.There is a protruding garden face at top 91 and middle part 92, and a recessed garden face is arranged at bottom 93, form an inflexion face between mid portion 92 and bottom 93.In preferred version, container 9 is by the glass manufacturing, so that observe the process that takes place in container 9.On the roof on top 91, form pipe 95,96 and 97.They are closed, and are used for injecting initial material to container.

Container 9 has two holes, and at container maximum gauge height, 92 upper angled stretches into from the middle part for pipe 98, and pipe 98 " equator " and each tangential plane with respect to container 9 are acute angle, and it is inside slightly or outward-dipping on the direction in container 9 to manage 98 axis.This angle is a bit larger tham 30 °.The bottom open end in the bottom 93 of container 9 is opened in second hole.The peripheral passage comprises pump 2, and blender 1 and four pipes 4,5,6 and 7 are arranged between bottom 93 and the tipping tube 98.

With reference to accompanying drawing 4 the 2nd scheme is described.In blender 1, by pump 2, container 9, outlet 8 and pipe 4,5,6 and 7 form loop.

The device of how now describing with Fig. 4 prepares water/hydrophobic liquid without emulsifying agent.At first, distilled water 9.5l is injected container 9 by pipe 97, then the 0.5l saualane is injected container 9, blanked-off pipe 95 and 97 by pipe 95.Wherein container 9 can be full of water and spiny dogfish oil fully, or its top is empty.Arrange the unlatching pump with this.The flow direction is shown in Fig. 4 arrow.When water and saualane introducing blender 1, their flow into and pass tangential hole 15 and form eddy current for the first time in hollow member 13, and this is to form with above-mentioned same mode.And then water and saualane tangentially flow into container 9 by tipping tube.

Water and saualane oil static in container 9 begin rotation and form eddy current for the second time.For the state that reaches in road, eddy current stage casing needs a period of time (about 1～2 minute).The about 50r.p.m. of rotational speed of eddy current at topmost and maximum gauge place.Basically press index law rising rotating speed downwards.Like this, water and saualane circulate in closed system and stop up to pump 2.Mixture flow stop after, open cock, from porus excretorius 8 discharge waters/saualane oil mixture.

Referring now to Fig. 5 Fig. 6 third party's case of the present invention is described.Represent the part identical with identical code name with first scheme.Third party's case and the main difference of first scheme are that a jet pump 50 that is connected blender 1 is set in closed system.

In this scheme, container 30 comprises a lid, pipe 31 and 32, and initial material injects container 30.Its corresponding pipe 6 by being positioned at position, its underpart ', outlet 8 and pipe 7 are connected with pump 2.Effuser 4 is connected in the outlet of jet pump 50, and the internal structure of jet pump 50 as shown in Figure 6.Jet pump inlet tube 54 is connected with container 30 by pipe 51, the function of jet pump is the mixing that promotes different liquids, and jet pump 50 has as shown in Figure 5 a hollow Cylinder shell, the interior space that nozzle 53 inserts housings 52, near the formation garden cylindrical space nozzle 53 top tube connectors 4, nozzle tip.Inlet tube 54 inserts in the wall of housing 52, and inlet tube 54 hollow lumen are connected with the garden cylindrical space near nozzle tip.In this example, adopt water stream injection pump.But also available in the method arm replaces water stream injection pump, and this pipe outlet side is connected to the import example of blender 1.

Describe now and how need not add emulsifying agent introducing hydrophobic liquid and enter and prepare stable hydrophilic liquid/hydrophobic liquid mixture in the hydrophilic liquid with Fig. 5 device shown in Figure 6.

At first, 9.5l ethanol is injected in the cock of tube used for bottom pouring 31 in container 30, and the then cock of tube used for bottom pouring 32 will be injected container 30 as the 0.5l saualane of initial oil.Blanked-off pipe 31 and 32 cock.After pump was opened, the rich saualane fluid in the container 30 was sprayed into pump 2, and by managing 4, jet pump 50, blender 1 and pipe 5 cause to the container 30 mobile, thereby form a closed system.In addition, the rich ethanol liquid in container 30 is injectedly gone into jet pump 50 by managing 51.In this closed system, ethanol and saualane mix by circulation.In the method, form ethanol and saualane oil mixture.

From as can be seen above-mentioned,, can mix multiple material and do not consider its component as adopting blender 1.

In addition, as adopting blender 1, can stablize and mix at least two kinds of liquid equably.

The similar device shown in Figure 4 of device shown in Figure 7.Pump 2 and blender 1 once were used in first scheme, and container 9 once was used in the alternative plan, and also having used oxygen supply source of the gas 60 and injector 61(here is not spicule).Source of the gas 60, injector 61 and pipe 97 are connected to the pipe 68(68a that has glass cock 62,63 and 64 respectively, 68b, 68c) on.Pipe 95 is connected with pipe 65, manages the insertion of 65 ends and is equipped with in the gatherer 66 of water.Gatherer 66 connects a glass cock 67.

At first tube used for bottom pouring 96, inject hydrophobic liquid octane 10l in container 9, blanked-off pipe 96.

Open glass cock 62 and 64, by injector 61 starting pressure elements (piston) 61a within it; Open glass cock 63 and enter the air that the inside is discharged in the peripheral passage with spray oxygen; It is 200ml that the pressure elements of adjustment injector 61 makes measurement category.After closing glass cock 63, the water level in the gatherer 66 is the same with the water level in the pipe 65.Close glass cock 67.Pump 2 starts, and pressure reduces in the container 9, and the pressure in the pipe 65 also reduces, and makes water level in the pipe be higher than water level in the gatherer 66.Pump was stopped twice in one day.Oxygen in injector 61 is pressed into the peripheral passage by pressure elements 61a, thereby makes water level in the gatherer 66 equal to manage water level in 65 again.Oxygen uses up in injector 61, by above-mentioned same quadrat method, opens cock 63, and source of the gas 60 is connected on the injector, and oxygen spray is gone into injector 61.Carry out a series of experiment in a manner described.Move 28 days and absorb 7440ml/10l(21 ℃ of oxygen).This value is equivalent to 2.4 times of saturation solubilities.

After experiment stops, stop pump 2.Keep system's original state.Stopping pump after 12 hours, measurement collection device 66 water levels are not observed not variation.Therefore, can think that the above-mentioned octane that contains excessive oxygen is stable.

Making hydrophilic liquid with 100ml methyl alcohol replaces octane similarly to test.

Move 28 hours and absorb 6640ml/10l(21 ℃ of oxygen), this value is equivalent to 2.8 times saturation solubility.

After finishing experiment, close pump, keep system's original state.Stopping pump after 12 hours, measurement collection device 66 water levels are not observed not variation.Therefore, the methyl alcohol that contains excessive oxygen is seldom.In this example, container 9 is used for forming eddy current for the second time, available any unit feeding liquid and make gas enter blender 1.

Be used for measuring device example such as Fig. 8 of the stability of the mixture that contains gas or hydrophobic liquid or hydrophilic liquid.

Conical flask 76 is mounted with the octane that 100ml contains excessive oxygen, and air is injected into upper space.Conical flask is arranged on the test stand 77, heats with burner 78 in its underpart.Conical flask 76 tops are connected with hose type cooling tube 74 with joint glass.This cooling tube is used the water quench (not shown) always.Seal with stopper 73 on hose type cooling tube top, and be connected on the jet pump 70 by glass tube 72 and siloxanes pipe 71.At first adjust piston to 0 position, the gas detector (being supplied with by Gastec company) that is used for surveying oxygen temperature is measured open-air oxygen concentration, finds that its concentration is 20.8%.Then loading contains the octane of excessive oxygen and boils with burner in conical flask, and by boiling, the pressure elements of compression injection device is pushed back.Start injector 70, the oxygen concentration of measuring in the injector 70 is 22.1%.Boil same sample with 2 hours, measure with above-mentioned same method, oxygen concentration is 22.1%.So, above-mentioned in over-saturation state (about 2.3 times) octane oxygen content be stable.Press said process, use same measuring instrument, the methyl alcohol that contains excessive oxygen is carried out similar stability measurement test.Middle in the open oxygen concentration is 20.8%.Oxygen concentration after boiling in 1 hour is 21.9%.Like this, boiled at 2 hours the position concentration also be 21.9%.Therefore, above-mentioned oxygen content in over-saturation state (about 2.7 times) methyl alcohol is to be in the stable state.

Replace oxygen methyl alcohol to be tested equally the about 1.8 times of saturation solubilities of carbon dioxide content in the methyl alcohol with carbon dioxide.In stability test, at about 1.35 times of saturation solubility steady concentration states.Thereby can think that if use the blender of this example a kind of gas can mix with another kind of gas is stable under the over-saturation state.

Water/oleovitamin A the drop that obtains according to first scheme is to collect from the upper and lower of container 30 and drip into preparation with syringe.The mixture of the water/oleovitamin A that is used to prepare, the Nicon that provides with Nippon Kogakusha is F.2 in ASA(American Standard Association) take pictures (magnifying power 600) under 1000 the speed, this machine is connected a light microscope (the M-862 type that Carton company provides).Confirmed that the plain A oil of little life disperses equably with the droplet of about 500nm size.In order to keep the stability of water/oleovitamin A mixture, mixture is stored in the insulating box that keeps 50 ℃ 13 days with sealing state, and as above-mentioned same method observe mixture with microphotograph.Find the same basically with firm mixed state.After, about 4ml water and vitamin mixtures are positioned in the cube shaped cell, after adjusting slit (wide=0.1mm), laser beam facing to being sent by laser beam source device (as the GL-803N that is made by NaKamura Rika Ko O K.K.) shines cell with laser beam.The result has confirmed Tyndall phenomenon.Then cell is placed on microscopically (by the BH-2 of Olympus Optional CO.Ltd. manufacturing) and above-mentioned laser beam device and constitutes ultramicroscope together.The laser beam that passes through above-mentioned slit that produces with laser beam device shines cell.The result has confirmed the existence of oil droplet, and Brownian movement has appearred in same confirmation.Sample as a comparison places container with the mixture of the water of 10ml oleovitamin A and 90ml, with ultrasonic washer (as " the SONO CLEANER " that make by Kaijyo Denki K.K. (CA-2480) the long-time stirring.The mixture that generates left standstill in room temperature under the tight seal state one day, and the result confirms that the water in container has separated with oleovitamin A, and the water of bottom is transparent and haze-free.When each droplet of the water of oleovitamin A that places the top on the single preparation with above-mentioned observation by light microscope and bottom, water droplet and oil droplet are not the mixtures of water and oil.Do not observe oil-containing and moisture in oil droplet in water droplet with above-mentioned ultramicroscope yet.

The same confirmation is long by circulation timei of the scheme of Fig. 1, and drop is very thin.Water/oleovitamin A mixture to the water that adds the hotwork preparation evaporates, and oleaginous material is to the adherence of preparation really.When water/saualane oil mixture is similarly tested, can obtain same as mentioned above result.

Same check the invention described above the first, the second, the water that makes with 1l water and 9l gasoline (as hydrophobic oil) in third party's case and the physical state of gasoline mixture.Confirmed that by light microscope drop size is the same basically, its size is about 500nm, and is dispersed in the oil.In addition, with above-mentioned similar, Tyndall phenomenon has taken place; Confirm the existence of water droplet with supermicroscope, and confirm the Brownian movement of water droplet.And then, when mixture is left standstill a segment length after the time, observe the oil-in-water part on top, the Water-In-Oil part in the bottom with colloid shape stable existence.In addition, when the mixture that generates with the 3000rpm centrifugation in the time of 5 minutes, confirm in the centrifugation product with above-mentioned light microscope, though not observing water droplet exists but Tyndall phenomenon occurred, and, observe the centrifugation part with ultramicroscope, Brownian movement also takes place in the alleged occurrence water droplet.Water droplet size is estimated as about 100nm.

In addition, prepare mixture with above-mentioned excusing from death ripple washer, at room temperature, allow the mixture that makes leave standstill 1 hour after, become water and gasoline, lower aqueous is transparent.

When the hydrophilic liquid for preparing by first scheme/when hydrophobic liquid mixture ethanol/oleovitamin A was taken pictures with said method with microscope, affirmation plain A fluid of little life in ethanol dripped the about 500nm of size.With compare after the firm mixing, mixture be placed in 50 ℃ of insulating boxs preserve 20 days after, the distribution of ethanol and the plain A oil of little life does not change basically.Heating to boil off moisture, confirms the viscosity of oil substances to preparation as the ethanol/oleovitamin A of preparation.

When ethanol/when the saualane mixture is similarly tested, can obtain result same as described above.

According to this programme, can obtain the mixing of a kind of liquid and a kind of gas equally.Yet this programme is not limited to the mixing of this mixing and the whole a kind of gas of several liquid or several liquid and several gases.
