Detailed description of the invention
Further describe the technical solution of the utility model below, but described in claimed scope is not limited to.
A kind of melting smoke eliminator as depicted in figs. 1 and 2, comprise collecting hood 1, front carrier pipe 3, insulation cover 4, rear carrier pipe 5, control of dust gather smoke-box 11 and fountain dust falling device 16, described collecting hood 1 is installed on the top of the outlet flue of smelting furnace 2; Described collecting hood 1 is tightly connected with the input port of the front end of insulation cover 4 by front carrier pipe 3, and the air inlet that the delivery outlet of described insulation cover 4 rear end gathers smoke-box 11 by rear carrier pipe 5 and control of dust is connected, and described insulation cover 4 is installed on aluminium liquid delivery chute 8; Described control of dust is gathered smoke-box 11 and is connected by the air inlet of tube connector 15 with fountain dust falling device 16, the top of described fountain dust falling device 16 is provided with exhaust outlet 21, bottom is provided with scavenge port 19, and inside is provided with wind isolation board 20, moisture film purification plate 17 and spray equipment 18.Utilize the waste heat of gas melting furnace flue further, flue gas is heated to insulation cover by the inner chamber of the insulation cover 4 of hollow, and then the temperature of the aluminium liquid 9 ensured in aluminium liquid delivery chute can not reduce, and both ensure that the crudy of product, has not needed again to increase input.
The inside that described control of dust gathers smoke-box 11 is provided with perforated baffle 12, the madial wall that upper end and the control of dust of described perforated baffle 12 gather smoke-box 11 is fixedly connected with, the bottom that described control of dust gathers smoke-box 11 is provided with fish belly plate 13, and the minimum point of described fish belly plate 13 is provided with dust-exhausting port 14.When flue dust enters after control of dust gathers smoke-box 11, flue dust obtains abundant reduction of speed, big dust particle can natural subsidence in fish belly plate 13; Perforated baffle 12 plays interference flue dust and flows to, and reduces the effect of flue dust flow velocity, is convenient to improve granule dust collection, effect of settling to greatest extent; Fish belly plate 13 minimum point is provided with dust-exhausting port 14, is convenient to regularly or quantitatively remove.
The below of described scavenge port 19 is also provided with sedimentation basin 22, and the side of described sedimentation basin 22 is connected with purified solution storage pool 23 by being separated wall, and described sedimentation basin 22 arranges the height of side lower than other positions of separation wall.When fume gases to enter from lower end fountain dust falling device 16 rise gradually time, through the moisture film purification plate 17 containing alkaline moisture film, dust granules is captured, and flows through scavenge port 19 enter sedimentation basin 22 after moistening weightening finish along wind isolation board 20; Acidic flue gas and alkaline moisture film purification plate cross, and enter sedimentation basin 22 after acid-base neutralization through scavenge port 19; Clean gas after depositing dust, disacidify, discharges from the exhaust outlet 21 at fountain dust falling device 16 top; The effect of wind isolation board 20 stops that the flue dust entering fountain dust falling device 16 is directly discharged from scavenge port 19.Dust-laden liquid precipitates after flowing into sedimentation basin 22, and sediment sinks at the bottom of pond, and the aqueous solution covers separation coping and enters purified solution storage pool 23, completes dirt, water is separated.
The length of described insulation cover 4 is less than or equal to the length of aluminium liquid delivery chute 8.Insulation cover 4 can reduce the heat dissipation capacity of aluminium liquid in course of conveying, heated to the aluminium liquid in delivery chute by flue gas simultaneously, effectively prevent temperature in the process of aluminium liquid conveying from reducing and occurring that low melting point composition shifts to an earlier date crystallization, forming element Fu Ji district, cause component segregation, and in blank, form crystallographic differences layer, in the production of follow-up sheet material, easily crack defect and performance difference.
At least one inside in described front carrier pipe 3 and rear carrier pipe 5 is provided with blower fan 10.Ensure that the flue gas circulation in pipeline is smooth and easy, ensure the heat insulation effect of insulation cover 4.The utility model structure is simple, solves the problem of insulation cover insulating power deficiency and the problem of flue gas environmental pollution.
