In view of the poor dust removal effect of the converter flue gas purification and gas recovery system, the phenomenon that the gas fan impeller sticky ash seriously affects the fan operation, the problems existing in the second valve throat RD valve are analyzed. Based on the analysis, several modifications are made to the RD valve. For example, for the first time in China, the multi-pipe water supply to the water tank was adopted. According to the process requirements, a special-purpose nozzle for RD valve was developed, which achieved good results, restored the working performance of venturi dust removal, improved the dust removal efficiency and saved circulating water Dosage, operating conditions significantly
