Research Summarize about Controlling Technology of Ultrafine Powder

Abstract

PM2.5 has serious harm to human health and the environment, coal-fired power plant flue gas emission is one of the important sources of PM2.5, however dust removal equipment for PM2.5 and finer particulate collection efficiency is very low.Mixed dust removal technology have various problems such as cost increasing , complex operation, the material requirements and capture efficiency of fine particle is not obvious. Coagulation as an effective method of collecting sub-micron particles, has good prospects for development.Further study of the mechanism of coagulation and coagulation technology in practical application of industrial production became focus of future research.
