Abstract
The invention discloses a high-energy device for extracting lithium and silicon materials and relates to a method for extracting lithium and silicon materials. The device mainly consists of an electric furnace, a silicon extraction facility and a lithium extraction system. The work scheme is that: after the lithium and silicon-containing raw material is melted in the electric furnace, a mixed fuel jet nozzle is started and the liquid raw material is atomized; air flow enters a high-energy electromagnetic chamber; electrons are separated under the acceleration of Lorentz force generated by the magnetic field; positive silicon ions are absorbed by an electric silicon target; other non-absorbed charged particles are still controlled by the intermediate-frequency electromagnetic field to fly over a magnetohydrodynamic generator and then subjected to residual heat conversion or power generation by a steam generator, and the lithium material is recycled from the tail gas. The conventional industrial extraction of lithium material is mostly realized by a sintering method, and polysilicon is prepared by a chemical method; the invention not only overcomes the shortcomings of heavy pollution and high energy consumption of the sintering method and the chemical method, but also can extract the lithium and silicon materials at the same time, while reducing the cost by combining magnetic fluid and residual heat conversion generation effect.
Description
Technical field:
The present invention relates to a kind of method of extracting lithium and silicon materials, particularly relate to a kind of high-energy rig that extracts lithium and silicon materials.
Background technology:
Industry is at present extracted lithium material and is used sintering process more, preparation polysilicon chemical method commonly used; The present invention overcomes aforesaid method to pollute the weakness big, that energy consumption is high, designs a kind of high-energy rig that extracts lithium and silicon materials, can extract lithium and element silicon material simultaneously, and combines magnetic fluid and waste heat conversion power generation system to reduce the product cost.
Summary of the invention:
The method that the present invention extracts lithium and silicon materials is to adopt a kind of high-energy rig that extracts lithium and silicon materials; This device is made up by three parts.
First part is the raw-material electric furnace of fusing (mainly being burner hearth, three-phase electrode, mixed fuel gas injection mouth).
Second section is to carry silicon facility (mainly being single-phase electric arc groove, high energy solenoid chamber, high voltage electric silicon target, magnetic control coil).
Third part is to extract lithium material system (mainly being passage, Magnetohydrodynamic(MHD) generator, vapour generator, elemental lithium pond for recovering).
Programme of work is: the starting material that at first will contain lithium and element silicon are poured the electric furnace thorax into, the three-phase electrode switch that closes, fusing starting material.Then open the tracheae valve and will mix combustion gas and import spray jet, bright eruption impacts the starting material that melted and swashs and spatters atomizing then.The accent of mist vapour through furnace bosh turns to the high energy solenoid chamber after entering single-phase electric arc groove gasification; Because of sharply drawing high temperature, electric arc makes monad in the air-flow (raw material contains) ionization rapidly; Again because the quality of ion and electronics is huge poor; The Lorentz force that moving charge in the air-flow produces by the magnetic field of high energy solenoid chamber is quickened to separate, and the silicon ion of positively charged is received by negative polarity high voltage direct current silicon target; But other can not or fail then still to be moved ahead along the passage of middle frequency electromagnetic field control by the charged particle that electric silicon target receives in the air-flow; And very fast through being carried out waste heat conversion or generating by vapour generator again behind the Magnetohydrodynamic(MHD) generator; Tail gas is then introduced the elemental lithium pond for recovering, the emptying of cleaning residual air.
Description of drawings:
Below in conjunction with accompanying drawing and embodiment, the present invention is further specified; Fig. 1 is to use organigram of the present invention.Among Fig. 1: 1, spray jet 2, electric furnace thorax 3, three-phase electrode 4, single-phase electric arc groove 5, high energy solenoid chamber 6, magnetic control coil 7, electric silicon target 8, Magnetohydrodynamic(MHD) generator 9, vapour generator 10, elemental lithium pond for recovering
Present embodiment is by 1 among Fig. 1---10 facility assemblies.
Embodiment:
In Fig. 1, after the raw material lithionite in the electric furnace thorax (2) is become liquid by the arc light heating and melting of three-phase electrode (3), Open valve will mix combustion gas (methane and air) and import spray jet (1), and bright eruption swashs and spatters the starting material that melted and make it atomizing then.Mist vapour by the furnace bosh accent get into single-phase electric arc groove (4) by electric arc hurriedly draw high temperature surpass 5000 the degree directive high energy solenoid chambers (5); Because the quality of ion and electronics is huge poor, the Lorentz force that the moving charge in the air-flow produces by high energy solenoid chamber 20,000 gauss magnetic fields is separated rapidly, and the silicon ion of positively charged is received (collection silicon) by negative polarity high pressure (10000V) direct current silicon target (7); But other can not or fail to be moved ahead by the EM field passage that the charged particle that electric silicon target receives is then still deployed to ensure effective monitoring and control of illegal activities along intermediate frequency magnetic control coil (6) in the air-flow; And, carry out the conversion of magnetohydrodynamic generator and waste heat very fast through the passage that links of Magnetohydrodynamic(MHD) generator (8) and vapour generator (9); At last, tail gas is introduced elemental lithium pond for recovering (10), and the elemental lithium material is collected; The emptying of cleaning residual air.
Claims (1)
1. high-energy rig that extracts lithium and silicon materials, its primary structure characteristic is: spray jet (1) is arranged at electric furnace thorax (2) top, and burner hearth bottom is established three-phase electrode (3), and burner hearth waist accent is communicated with single-phase electric arc groove (4) and produces the high energy solenoid chamber (5) of 20,000 gauss magnetic fields; Intermediate frequency magnetic control coil (6) and electric silicon target (7) at the locular wall assembly, the indoor channel tail joins Magnetohydrodynamic(MHD) generator (8) and vapour generator (9) and elemental lithium pond for recovering (10).
