Aluminum alloy die-casting waste gas treatment device

Abstract

The invention discloses an aluminum alloy die-casting waste gas treatment device which comprises a box body and a liquid supplementing box, filter plates are fixed to the inner walls of the two sidesof the box body through screws, air outlet holes distributed at equal intervals are formed in the outer walls of the tops of the filter plates, and a first round hole is formed in the outer wall of one side of the box body; and a water inlet pipe is fixed to the inner wall of the first round hole through screws, a bubble tank is inserted into the outer wall of the bottom of the water inlet pipe, and bubble holes distributed at equal intervals are formed in the outer wall of the periphery of the bubble tank. By arranging the filter plates, the atomizing nozzle, the plasma purifier and the activated carbon filter element, waste gas which does not react with reaction liquid passes through the filter plates, and the filter plates are formed by interweaving an elastic material and a related filter material so that the filter plates have elasticity and filterability and can bulge upwards, on one hand, the flow rate of the waste gas can be reduced, and thus the waste gas can react with the reaction liquid below the filter plates for sufficient time.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to an aluminum alloy die-casting waste gas treatment device. Background technique [0002] Aluminum die-casting is a pressure-casting part. It uses a pressure-casting machine die-casting machine with a casting mold installed, and pours heated liquid aluminum or aluminum alloy into the feed port of the die-casting machine, die-casts through the die-casting machine, and casts out the mold. Aluminum parts or aluminum alloy parts of limited shape and size, such parts are usually called aluminum die-casting parts, the aluminum alloy die-casting process will produce sulfur and nitrogen-containing tail gas, and will also emit a large amount of particulate matter, including dust And black smoke, aluminum alloy die-casting exhaust gas has high temperature and is corrosive. The exhaust gas dissolves in water and becomes acidic. Pollutants affect the production environment and dama...

Problems solved by technology

[0002] Aluminum die-casting is a kind of pressure-casting parts. It uses the pressure-casting machinery die-casting machine with the casting mold installed, and pours the heated liquid aluminum or aluminum alloy into the feed port of the die-casting machine. After die-casting by the die-casting machine, the mold is cast out. Aluminum parts or aluminum alloy parts of limited shape and size, such parts are usually called aluminum die castings. The aluminum alloy die casting process will produce sulfur and nitrogen-containing tail gas, and will also emit a large amount of particulate matter, including dust And black smoke, aluminum alloy die-casting waste gas has a high temperature and is corrosive. The tail gas is acidic when dissolved in water. Pollutants affect the production environment and damage the surrounding environment.

[0003] If the exhaust gas produced by general aluminum alloy die-casting leads to poor waste treatment effect, it will not be able to meet the qualified standards for exhaust gas emissions. After the exhaust gas with insufficient treatment is discharged, it will cause certain pollution to the atmosphere. An existing aluminum alloy die-casting Existing problems in the exhaust gas treatment device: the exhaust gas cannot fully contact and react with the absorption liquid
