Research on agglomeration combustion of dust hoppers in electrostatic precipitators based on the theory of sintering machine head dust characteristics
The ash hopper of the electrostatic precipitator at the sintering machine head of a certain steel plant experienced agglomeration and combustion,which affected the operation of the electrostatic precipitator at the machine head.This article focuses on the dust characteristics of the dust removed by the electrostatic precipitator at the sintering machine head.By detecting and analyzing the moisture content,composition,carbon content,and particle size distribution of the dust,the reasons for the agglomeration and combustion of the ash hopper in the sintering machine head electrostatic precipitator are clarified.Based on the theory of dust characteristics at the sintering machine head,solutions for the agglomeration and combustion of the ash hopper in the electrostatic precipitator are proposed.Research has shown that the proportion of water carbon,alkali metal oxides,and fine dust in the dust of the dust collector hopper is high,and the content of the first to third electric fields shows an increasing trend,leading to the occurrence of agglomeration combustion in the dust collector hopper.Therefore,it is proposed to control the humidity between 6%and 8%for sintering ingredients and to add a sonic blower to the ash hopper of the electrostatic precipitator to solve the problem of agglomeration combustion,which can provide reference for the treatment of agglomeration combustion in the dust hopper of the machine head electrostatic precipitator.
