Problems solved by technology

[0002] The acidic gas or alkaline gas produced in the production process of the prior art is generally all directly passed into the alkali washing pool or the pickling pool for alkali washing or pickling, because generally all contain a certain amount of dust in these gases, if not Dust removal treatment can easily lead to dust accumulation and precipitation in the washing tank, and the washed sediment is non-neutral, and the follow-up treatment cost is high

Abstract

The invention discloses a tail gas treatment device of dust-containing gas and belongs to the technical field of tail gas treatment. The tail gas treatment device solves the problems of poor tail gastreatment effect and high cost in the prior art. The tail gas treatment device comprises an acid / alkali washing pool and a dehydrating and drying bin and also comprises a dust removal bin and a dust fan, wherein the dust removal bin is connected with the acid / alkali washing pool through a gas delivery pipeline; the dehydrating and drying bin is connected with the dust fan through an air duct; thedust removal bin is divided into a conical sedimentation pool and a dust adsorption zone by a support board; the dust adsorption zone is divided into small adsorption zones through clapboards; adsorbents are filled in the small adsorption zones; dust through holes are formed in the support board; and the dust removal bin also comprises a flue gas inlet and a dust outlet. The tail gas treatment device disclosed by the invention can be used for treating dust-containing gas.

Description

technical field [0001] The invention relates to a tail gas treatment device for dust-containing gas, belonging to the technical field of tail gas treatment. Background technique [0002] The acidic gas or alkaline gas produced in the production process of the prior art is generally all directly passed into the alkali washing pool or the pickling pool for alkali washing or pickling, because generally all contain a certain amount of dust in these gases, if not Dust removal treatment can easily lead to dust accumulation in the washing tank and sedimentation, but the washed out sediment is non-neutral, and the follow-up treatment cost is high. Contents of the invention [0003] The object of the present invention is to provide a tail gas treatment device containing dust gas, which has good tail gas treatment effect and low cost. [0004] The tail gas treatment device for dust-containing gas includes an acid / alkali washing tank and a dehydration drying bin, and also includes a...
