Abstract

The invention discloses a casting exhaust gas acid mist purification tower, relating to the technical field of exhaust gas treatment. The casting exhaust gas acid mist purification tower comprises a vertical spray pipe, a vertical spray head, horizontal spray pipes and horizontal spray heads. When acid mist is subjected to purification, the acid mist is firstly purified through a packing layer tobasically remove large particles of impurities; after passing through the packing layer, the acid mist comes into contact with spray liquid; the spray liquid first enters a liquid inlet pipe, then enters the vertical spray pipe from the liquid inlet pipe, and is sprayed horizontally through the vertical spray head on the vertical spray pipe; at the same time, the spray liquid in the vertical spraypipe also enters into each horizontal spray pipe and is sprayed down through the horizontal spray heads on the horizontal spray pipes. Since the horizontal spray pipes are evenly arranged in the circumferential direction of a tower body, the spray liquid is evenly and fully sprayed onto the top of the packing layer, and therefore, the acid mist is more fully contacted with the spray liquid afterpassing through the packing layer.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to a casting waste gas acid mist purification tower. Background technique [0002] As we all know, a lot of smoke, dust, hot gas and other waste gases will be produced in the casting production process, especially in the equipment manufacturing industry, the relatively common resin-coated sand is currently used, and it is even more volatile and Pyrolysis of a large amount of formaldehyde, phenols, amines and other organic substances with peculiar smell. These toxic and harmful gases not only deteriorate the production environment, but also cause serious pollution to the atmosphere around the factory area. Effective treatment must be carried out to ensure that the national relevant emission standards. [0003] There will be acid gas in the waste gas of foundry, because the acid gas is very harmful to the human body and the environment, usually these harmful gases must be...
