Description
Technical field
The present invention relates to silica micropowder purifying machine, especially relate to adjustable super-high pressure pulse static silica micropowder purifying machine.
Background technology
After silicon powder was produced in industry, because the influence of silicon powder self character, silicon powder could be in industrial use after generally all will purifying through machinery.Continuous development along with science and technology, the silicon powder technical requirements that is used for new high-tech industries such as high-grade paint, senior filler, insulating material, electronic package material and aerospace is also more and more higher, higher to the purity requirement of silicon powder especially, silicon powder purity is high more, the flowability that has is good more, dispersiveness is high more, thermal conductivity is more little, electric conductivity is low more and corrosion resistance nature is strong more, while is along with the raising of silicon powder purity, its market sale price is also more and more higher, and economic benefit of enterprises also just improves.But along with the raising of silicon powder purity, the technical difficulty that its silicon powder is purified is also just increasing.At present, being used for silicon powder machinery purifying plant mainly adopts big whirly combined type, ladder cyclone type and common static to combine to purify, but the silicon powder purity after purifying generally all can only reach 92%, the market sale price is about 1100 yuan/ton, even the silicon powder purification purity that has is below 90%, and the market sale price is about 800 yuan/ton.Therefore not only purification purity is not quite high for the silicon powder of existing machinery purifying plant purification, can not be suitable for the technical requirements of new high-tech industry to silicon powder, and influence economic benefit of enterprises.
Summary of the invention
Problem at silicon powder machinery purifying plant in the above-mentioned prior art exists the invention provides a kind of not only compact construction, easy for installation, and purification purity reaches the adjustable super-high pressure pulse static silica micropowder purifying machine more than 96%.
The technical scheme that the technical problem to be solved in the present invention is taked is: described adjustable super-high pressure pulse static silica micropowder purifying machine comprises by outer straight tube, interior straight tube, conically shaped, flue-dust retainer and ash-valve are formed roughly selects the whirlwind tube, in select whirlwind tube and selected whirlwind tube, straight tube is arranged in the outer straight tube in described, conically shaped is positioned at outer straight tube below and is connected with outer straight tube, described flue-dust retainer and ash-valve are arranged on the conically shaped lower end, the outer straight tube sidewall of roughly selecting the whirlwind tube is provided with blast inlet, outer straight tube upper end at selected whirlwind tube is provided with tornado dust collector, roughly select the whirlwind tube with in select in the outer straight tube of whirlwind tube and be provided with the static electric field that links to each other with the ultra-high voltage electrostatic power unit, the described whirlwind tube of roughly selecting, in select the whirlwind tube to link to each other successively and be formed with along the ventilation opening of air-flow rolling tangential direction at connecting place with selected whirlwind tube, be provided with the wind speed adjustable plate in ventilation opening, selected whirlwind tube is provided with the setting device that can adjust the interior straight tube height location in the selected whirlwind tube.
Principle of work of the present invention is: the flue gas that produces when hot stove of silicon mine is produced sucks roughly selecting in the whirlwind tube in the purifying machine by the blower fan in the system, the centrifugal principle that utilizes tornado dust collector with the meal dirt in the flue gas (as carbon granule, ore particle, ashes) separate, and to being blended in ultra micro footpath impurity in the silicon powder (as iron, calcium, aluminium, magnesium, potassium, sodium etc.) metal oxide, adopt super-high pressure pulse static to its electric charge ionization, make the metal oxide cohesion of ultra micro particle diameter increase thick, under centrifugal action, it is separated, and smart silicon powder is discharged collection from selected whirlwind tube air outlet, coarse particles and impurity are discharged from the impeller ash-valve, air-flow is taken over motion by zigzag, when roughly selecting the not separated grit of whirlwind tube and from ventilation opening enters, select the whirlwind tube, from the center the centrifugal grit that comes out more close barrel, form the sepn process of stripping layer, improved the separating effect of whirlwind tube, crude particle dust is separated fully, in the thick silicon powder of ultra micro, contain iron, calcium, aluminium, magnesium, potassium, during metal oxides such as sodium, because the ratio resistance of these metal oxides is higher, and the ratio resistance of dust has a significant impact the efficient of electric precipitator, when the ratio resistance of dust is unfavorable for that electric precipitator is caught dirt, need take measures to regulate the ratio resistance of dust, it is in be fit to the scope that static captures.Because the ratio resistance of metal oxide mostly more than 5 * 1010 Ω cm, therefore should not adopt above-mentioned static to capture dust and carry out the silicon powder purification in the silicon powder.The present invention adopts ultra-high voltage (more than the 150KV) pulse static to carry out the purification of silicon powder, improves the pole span distance, reduces the obstacle in the flow field, makes the gas stream field energy fill smooth performance of performance and centrifugal force.
The present invention utilizes the wind speed adjustable plate to regulate the ventilation opening wind speed, guarantee that fluctuate the in working order wind speed of backspin air duct ventilation opening of flue gas remains in the setting range, so that select wind speed to reach best centrifugal effect, the present invention also adjusts interior straight tube height location in the selected whirlwind tube by setting device, control the separation resistance in the selected whirlwind tube, when interior straight tube descends, separating resistance increases, the separation efficiency height, good separating effect, thereby can isolate the silicon powder of different purification purity, to satisfy the market technical requirements different by adjusting the interior straight tube height location in the selected whirlwind tube on this same device to silicon powder.
The present invention can separate the granule dusts such as metal oxide in the silicon powder effectively, can improve the purity of silicon powder greatly, the silicon powder purification purity reaches more than 96%, can satisfy the silicon powder technical requirements that is used for new high-tech industries such as high-grade paint, senior filler, insulating material, electronic package material and aerospace, improve the added value of silicon powder greatly.
