Abstract
The invention provides a silicon micropowder recycling system, which comprises a silicon melting furnace, a furnace gas pipe and a bag dust removing device, wherein a feed opening is formed in the silicon melting furnace; the silicon melting furnace is connected with the bag dust removing device through the furnace gas pipe; the bag dust removing device comprises a bag, a vibrating motor, a gas outlet and a dust outlet; a powder flow division device is arranged below the dust outlet; a partition plate is arranged on the middle part of the bottom surface of the powder flow division device; a handle is arranged on the partition plate; two powder outlets are formed in the powder flow division device; one powder outlet is connected with a stirring device, and a water pipe and a reducing agent inlet are arranged on the stirring device; the other powder outlet is connected with a sealing device, and a high-pressure gas pipe is arranged on the sealing device. According to the silicon micropowder recycling system, the powder flow division device is arranged below the dust outlet, and is connected with the stirring device and the sealing device to classify powder, so that the silicon micropowder recycling system is environment-friendly, and the cost is lowered.
Description
Technical field
The present invention relates to silicon technical field of processing equipment, specifically relate to a kind of silicon powder recycling system.
Background technology
Molten silicon stove is the common equipment in silicon processing, waste gas can be produced in molten silicon process, wherein containing flue dust and pernicious gas, containing a large amount of silicon powders in flue dust, the existing cleaning equipment to molten silicon furnace exhaust gas, generally just purifies pernicious gas wherein, the indices of the gas entered in air is made to reach standard, but the flue dust of some recoverables is not recycled, not only contaminated environment, also wastes resource.
Summary of the invention
The object of the invention is the shortcoming for above-mentioned prior art, a kind of silicon powder recycling system is provided.
Its technical scheme is:
A kind of silicon powder recycling system, comprise molten silicon stove, furnace gas pipe and bag-type dust collector, described molten silicon stove is provided with charging aperture, described molten silicon stove is connected by furnace gas pipe with between bag-type dust collector, bag-type dust collector comprises cloth bag, vibrating motor, gas outlet and ash hole, powder part flow arrangement is provided with below described ash hole, the middle of described powder part flow arrangement bottom surface is provided with dividing plate, described dividing plate is provided with handle, described powder part flow arrangement is provided with two dust outlets, a dust outlet is connected with agitating device, described agitating device is provided with water pipe and reducing agent import, another dust outlet is connected with encryption device, described encryption device is provided with high-pressure gas pipe.
Because the middle of powder part flow arrangement bottom surface is provided with dividing plate, dividing plate is provided with handle, powder part flow arrangement is provided with two dust outlets, a dust outlet is connected with agitating device, another dust outlet is connected with encryption device, when powder is entered in powder part flow arrangement by ash hole, pull handle, baffle plate is made to block the dust outlet connecting encryption device, powder is flowed in agitating device, in agitating device, adds water and some reducing agents, stir, make powder agglomeration become block, the product obtained again is put into molten silicon stove and is smelted; All right, pull handle, powder is flowed in encryption device, utilize the pressure of gases at high pressure to improve the density of silicon powder, be convenient to packaging, after being encrypted by powder, be used as construction material.
