Based on the analysis of the ventilation resistance of the dust removal system by ventilation with long forcing duct and short exhaust duct and combined with the performance test of the dust removal system, the cause of small exhaust air quantity of the dust removal system in its site application was found out. Through analyzing the ventilation resistance of the dust removal system and by combining with its performance test, a resistance reduction scheme by changing the water spraying frame and the number of the filter layers of the original dust removal system was put forward. This scheme was applied at the site, the ventilation resistance of the dust removal system was successfully reduced, the air volume increased by 120 m3/min, and good dust removal effect was achieved.
