Description
Technical Field
The utility model relates to a multifunctional integrated tower for blast furnace gas.
Background
The sulfur in blast furnace gas of iron and steel enterprises mainly comprises H2S and COS, wherein H2S accounts for about 30%, and COS accounts for about 70%. H2The removal of S is relatively easy, and the key point and difficulty of the fine desulfurization of blast furnace gas lies in the removal of COS. The removal of COS can adopt an adsorption method or a hydrolysis conversion method, wherein the hydrolysis conversion method is to convert COS into H by a hydrolysis catalyst2S, then H is removed2And S. The blast furnace gas has complex components and contains dust, chloride ions and the like, which influence the service life of the hydrolysis catalyst. Therefore, in industrial applications, facilities such as a pretreatment column are added before the hydrolysis column. The tower body is more, the occupied area is large, and the investment is large.
