Research on Converter Gas Recovery and Dedusting Process
Converter gas recovery has always been a focus of energy recycling in the steelmaking system of iron and steel enterprises.Due to the imperfection of the current gas recovery process,there is a certain degree of volatility in the recovery rate,which leads to the waste of derived resources.Factors affecting the efficiency of gas recovery mainly in-clude the raw material conditions of the converter,oxygen supply conditions,time of gas re-covery,valve action time,and the amount of air intake at the mouth of the furnace,etc.Aiming at those factors,combining with the actual situation of Tangshan Steel,optimization measures are proposed in four aspects,namely,improving the dropping rate of converter hood,adjusting the fan speed,optimizing the hydraulic system,and interlocking the flue gas analyzer and the fan,so as to maximize the recovery of the converter gas and improve the purity of its recovery.
