SW型脱硫剂脱硫性能的研究

Study on the Desulphurization Performance of SW Type Desulphurizer

以硫酸烧渣为主要原料制备ＳＷ型脱硫剂，并对其脱硫性能进行了研究。对半水煤气、葡萄酒厂污水处理产生的沼气和焦沪煤气、水煤气中的Ｈ２Ｓ进行了工业脱硫试验。经半年以上运行证明：可使其Ｈ２Ｓ含量从３０００－５０００ｍｇ／ｍ３降为２０ｍｇ／ｍ３以下（符合国家标准），当脱硫剂工作硫容达３０％时可返回硫酸生产中，再生周期一般为３个月，其主要性能达到国内外同类产品水平。

A SW type desulphurizer has been developed by preparing it from pyrite cinders generated from the production process of sulfuric acid and its Performance of desulphurization was studied. Its application on a full scale of industrial production demonstrates that the SW type desulphurizer has a higher removal of H2S from marsh gas or coal gas and can reduce the concentration of H2S from 3000-5000 mg/ m3 to less than 20 mg/ m3 in compliance with the national standards. The desulphurizer has a working sulfur capacity of up to 30% and the main performances which are comparable with those of similar products in home and abroad.
