【 摘 要 】

The removal of industrial dust is mainly realized by various dust removal equipment. The electrostatic dust remover can remove more than 99.5% of the dust particles of various diameters, but the dust removal effect of particulate particles is not significant. Among them, for the finer particles in the dust, the dust removal effect is poor. After measurement, the efficiency of electrostatic dust removal is 80%-85% for fine particles with a particle diameter of 10-1μm [1]. With our higher demand for particulate emissions, improving the removal of industrial fine particulates is imminent. In the process of dust generation, dust particles collide or come into contact through various paths, thereby combining to generate larger particles, and this process becomes the condensation of dust. The dust agglomeration technology is generally used as a pre-treatment of the flue gas in the field of flue gas dust removal. By enriching the fine particles, the fine particles become larger, and then the dust is removed through the dust removal device.
