Equipment for treating industrial waste gas containing hydrogen chloride gas

Abstract

The invention discloses equipment for treating industrial waste gas containing hydrogen chloride gas. The equipment comprises a hollow reaction chamber, a treatment chamber, an air inlet pipe, an airoutlet pipe, particle reactants and a drainage device, wherein an inlet part and an outlet part are respectively formed in two ends of the reaction chamber; the treatment chamber is formed in the reaction chamber, and holes for gas to flow through, an air inlet end matched with the inlet part as well as an air outlet end matched with the outlet part are respectively formed in / arranged at at leastone part of the side wall; the particle reactants are arranged in a gap between the reaction chamber and the treatment chamber; and the drainage device is arranged in the treatment chamber and is usedfor guiding and shunting partial gas entering the air inlet end to the gap between the reaction chamber and the treatment chamber for several times and then guiding and shunting partial gas into thetreatment chamber. By arranging the drainage device, gas can enter the gap between the reaction chamber and the treatment chamber for several times, reacts with the particle reactants, is absorbed andthen enters the treatment chamber, so that the gas can be well purified and absorbed in the treatment chamber, and the treatment effect is good.

Description

technical field [0001] The invention belongs to the technical field of industrial waste gas treatment, and in particular relates to a treatment device for industrial waste gas containing hydrogen chloride gas. Background technique [0002] In the industrial production process, especially in the chemical industry and other industries, corrosive gases such as hydrogen chloride are often generated, which cannot be directly discharged into the outside air. Chinese patent CN107774113A discloses "a treatment equipment for hydrogen chloride waste gas", which uses solid particulate matter to initially adsorb hydrogen chloride gas, and then absorbs hydrogen chloride gas again by spraying to avoid the problem of processing residues. However, under this structure, the gas is taken in and out from the filter barrel, and the solid particles are arranged in the interlayer between the reaction barrel and the filter barrel, and more gas will flow directly to the air outlet in the filter bar...

AI Technical Summary

Problems solved by technology

However, under this structure, the gas enters and exits from the filter barrel, while the solid particles are placed in the interlayer between the reaction barrel and the filter barrel, and more gas will directly flow in the filter barrel to the gas outlet position and be discharged outward. , only a small amount of gas will enter the interlayer to react, the absorption effect is poor, and it is difficult to achieve a good waste gas treatment effect
