Problems solved by technology

[0002] At present, the acid waste gas treatment device in the pickling equipment in the metallurgical industry is the waste gas tower, which sucks the acid waste gas generated in the pickling process into the purification tower with a fan, and directly discharges it into the atmosphere after being sprayed with lye in the purification tower. The treatment process not only needs to consume a large amount of alkaline resources, but also cannot guarantee the compliance rate of waste gas, which still pollutes the environment

Abstract

The invention provides an improved device for recovering, processing and recycling acidic waste gas, which can recover and process the acidic gas to enable the acidic gas to be continuously recycled in a pickling line to ensure that the waste gas can not be discharged into the atmosphere, thereby achieving the purpose of zero draining of the waste gas. The improved device for recovering, processing and recycling acidic waste gas comprises a blower and a waste gas absorber, wherein the waste gas absorber comprises a waste gas absorbing tower and a recovering tank, wherein a gas transmission pipeline of the blower is connected with the waste gas absorbing tower; the recovering tank is connected with a pipeline at the lower part of the waste gas absorbing tower and is connected with a pipeline of a mixing device; and the mixing device is connected with the pickling line.

Description

(1) Technical field [0001] The invention relates to the field of waste gas treatment equipment, in particular to an improved recovery and treatment cycle device for acid waste gas. (2) Background technology [0002] At present, the acid waste gas treatment device in the pickling equipment in the metallurgical industry is the waste gas tower, which sucks the acid waste gas generated in the pickling process into the purification tower with a fan, and directly discharges it into the atmosphere after being sprayed with lye in the purification tower. The treatment process not only needs to consume a large amount of alkaline resources, but also cannot guarantee the compliance rate of waste gas, which still pollutes the environment. (3) Contents of the invention [0003] In view of the above problems, the present invention provides an improved acid waste gas recovery treatment cycle device, which can continue to recycle the acid gas into the pickling production line after recover...
