A magnetic fluid double-current generator mainly comprises a flow dividing tube (1), an ion current solenoid (2), a three-phase sine wave four-way throttle valve (3), an ion current coil (4), electrodes (5) and a power generation coil (6). The magnetic fluid double-current generator is characterized in that positive and negative ions of working mediums (come from plasma mixed gas or liquid of ion source) which flowed in high speed in the insulating flow dividing tube (1) are separated in a pipe constraint condition under the functions of electric field force or Lorentz force and respectively flow into the two electrodes (5) to achieve double-current power generation. The magnetic fluid double-current generator solves the problems that the existing magnetic fluid is low in converting efficiency of power generation energy, complex in structure, easy to corrode of electrodes, difficult to obtain the ultrastrong magnetic field, high in material requirements and only capable of generating electricity through direct current.

Description

The magnetic fluid double current generator

One. technical field:

The present invention relates to a kind of hydromagnetic generating device, is a kind of with the ionogenic interior device that can be converted into electric energy, even portion of energy wherein can be converted into fuel chemical energy or mechanical energy.

Two. background technology:

The principle of existing magnetohydrodynamic generation: be that plasma is ejected into a power channel the inside that is added with high-intensity magnetic field with ultraspeed, in plasma with the high-velocity particles of positive and negative electric charge, be subject to the effect of Lorentz force in magnetic field, respectively to two plate electrode skews that are arranged at perpendicular to the magnetic line of force and the high-velocity particles direction of motion, the charge generation voltage of two interpolars because gathering connects voltage just to can be used as DC generation in people's circuit or be converted to alternating current through inverter with wire and incorporates electric field into.

The simple shape of existing magnetohydrodynamic generation:

Magnetohydrodynamic generation is a kind of direct generation of electricity mode of 1950's research.Mainly be divided into open cycle and the large class of closed cycle two from duty cycle mode difference, the primary energy that uses can be fossil class A fuel A, nuclear energy or other energy.

The efficient of magnetohydrodynamic generation itself is 20% left and right only, but because its exhaust gas temperature is very high, the gas of discharging from magnetic fluid can be sent to general boiler and burn away into steam, the driving steam turbine generating, form efficient combined cycle generation, total heat efficiency can reach 50%～60%, is the highest in present efficiency power generation technology just under development.

Building up practical Large Magnetic fluid-steam power combined cycle generating unit also has following technical problem to need to solve:

A. magnetohydrodynamic generation is more much higher than general thermal power generation efficient, but its development progress is unhappy for a comparatively long period of time, and its reason is to follow its advantage and has produced a lot of technical barriers.In Magnetohydrodynamic(MHD) generator, operation be temperature at the conductor fluids of three, 4,000 degree, they are ionized gas under high temperature.For carrying out effective electrical production, therefore the gas conduction performance that has ionized, also will add the metal ions such as the potassium that is called as seed, caesium not enough therein.But when this air-flow that contains metal ion, by the power channel in high-intensity magnetic field, when reaching electrode, electrode is also corroded thereupon at a high speed.The rapid corrosion of electrode is the biggest problem that Magnetohydrodynamic(MHD) generator faces, the problems such as the seed spray that therefore causes in addition and recovery, mechanism's complexity, environmental pollution.

B. Magnetohydrodynamic(MHD) generator needs a powerful magnetic field, people all to think, really the generator for the production of scale must produce high-intensity magnetic field with superconducting magnet, and this also brings the difficult problem on technology and equipment certainly.

C. inverter.

D. high-temperature air preheater.

E. the generation of oxynitrides is controlled.

Recent years, scientist has had new progress selecting of conductor fluid, the metal (as sodium, potassium etc.) of having invented with low melting point is made conductor fluid, add volatile fluid (as toluene, ethane etc.) and promote flowing of liquid metal in liquid metal, avoided dexterously some difficult problems on engineering, also there has been new development the development aspect of making the material of electrode and fuel.But think to save money quickly and solve effortlessly that in magnetohydrodynamic generation, all difficult problems of the aspect such as technology, material are unpractical.
