What are the dust removal equipment in the metallurgical plant?

　　Metallurgical manufacturing is a heavy industry in various industrial productions. It is also relatively serious against air pollution, mainly air dust pollution. The existence of these pollutions causes serious damage to our living environment and must be fundamentally controlled. Iron and steel, casting, coking, steel making, etc., which are seriously polluted by metallurgical engineering, the key technologies of pollution control mainly use the flue gas generated in the metallurgical process to be effectively reused, and the emissions are discharged after being purified by the dust removal equipment.
　　The dust removal equipment commonly used in the metallurgical industry is:
　　Dust removal equipment commonly used in dust removal equipment of metallurgical industry can be divided into three categories: coarse dust removal equipment, semi-fine dust removal equipment, and fine dust removal equipment.
　　1. Rough dust removal equipment. In the classification of industrial dust removal equipment, the particle dust removal equipment that needs to be treated with a larger particle size is called a coarse dust removal equipment. Gravity dust removal equipment and cyclone dust removal equipment are commonly used in the metallurgical industry.
　　2. Semi-fine dust removal equipment. The particle dust removal equipment with a particle size of 20-6 to be treated is called a semi-fine dust removal equipment. Commonly used dust removal equipment washing tower, first-grade venturi, one-time bag dust removal equipment.
　　3. Fine dust removal equipment. A particle dust removal device having a dust particle size of less than 20 to be treated is referred to as a fine dust removal device. Electrostatic precipitators, bag dust removal equipment, etc. are common in dust removal equipment of metallurgical industry.
