转炉污泥干法脱硫新技术应用

Application of a New Dry Desulphation Method Using Converter Sludge

采用转炉污泥取代铸铁屑配制焦炉煤气脱硫剂，转炉污泥与稻壳体积配比为１：２，水分３０％～４０％，ｐＨ值８～１０。经过生产实践证明，脱硫效率达到９９．９％～９９．８％。既降低了煤气生产成本，减轻工人劳动强度，又提高了民用煤气质量，具有可观的环境效益与经济效益。

Cast iron scraps were replaced by converter sludge to make up desulphurizer for coke oven gas. Volume ratio of the converter sludge and rice husk is 1: 2 ; water content is 30%-40% and pH is 8-10. Production practice shows that desulphation efficiency reaches 99. 8%-99. 9%. It not only decreases produc- tion costs of gas and reduce workers' labour intensity but also increases civil gas quality. The mothed has significant environment benefits and economic benefits.
