Treatment tower for purifying of acid waste gas

Abstract

The invention discloses a treatment tower for purifying of acid waste gas. The treatment tower comprises an outer casing of a tower body, wherein one side of the outer casing of the tower body is connected with a gas exhaust through pipe; the gas exhaust through pipe comprises a gas exhaust through pipe body and nine branch gas exhaust through pipes; the nine branch gas exhaust through pipes are uniformly arranged at one side of the gas exhaust through pipe body; the gas exhaust through pipe body is communicated with the outer casing of the tower body; the outer casing of the tower body is fixedly connected with a cooling water tank through an inclined support frame; the cooling water tank comprises a cooling water intake pipe, a water tank body, a cooling water drain pipe and a through hole. The treatment tower has the advantages that the gas exhaust through pipe, the gas intake through pipe and the cooling water tank are arranged, the gas intake through pipe is communicated with a gas intake pipe, nine through holes are formed in the cooling water tank, the nine branch gas exhaust through pipes on the gas exhaust through pipe correspondingly penetrate through the nine through holes, and the nine branch gas exhaust through pipes are connected with the gas intake through pipe, so that when the waste gas enters the gas exhaust through pipe through the gas intake through pipe, the acid gas can be cooled by the cooling water in the cooling water tank.

Description

technical field [0001] The invention belongs to the technical field of waste gas treatment, and in particular relates to a treatment tower for purifying acid waste gas. Background technique [0002] The commonly used methods for waste gas treatment by waste gas treatment devices include adsorption method, absorption method, catalytic combustion method, thermal combustion method, etc. When selecting purification methods, the county should choose a method with low cost, less energy consumption and no secondary pollution according to the specific situation. Try to turn harm into profit, and fully recycle components and waste heat. In most cases, the petrochemical industry adopts methods such as condensation, absorption, and direct combustion due to high exhaust concentration. Paint construction, printing and other industries have low exhaust concentration. Using methods such as adsorption and catalytic combustion, these waste gases include: carbon dioxide, carbon disulfide, hyd...
