带钢酸洗液净化絮凝剂添加量对压滤的影响OA

In the process of strip pickling,some insoluble substances will fall off into the pickling solution along with the oxide scale of the strip steel.At present,most of them are removed by flocculation precipitation method,and the flocculation products can be separated by plate and frame filter press.The removal efficiency of insoluble matter and the operation effect of filter press are closely related to the amount of flocculant added.The process adjustment is carried out directly in the production line,which has the problems of long effective time and great effects on production.Through the laboratory test,this paper investigates the effect of the amount of flocculant on the removal efficiency and filtration time of insoluble matter.Based on the actual production operation parameters,it is determined that there is a certain relationship between the filtration time and the time required for the filter press to reach the maximum working pressure and the water content of the mud cake.This study can be used as a reference for the adjustment of actual production process parameters through laboratory tests.
