Description

Bag type dust removing equipment

Technical Field

The utility model relates to the technical field of dust removing equipment, in particular to bag type dust removing equipment.

Background

In recent years, with the rapid development of economy, metallurgical steelmaking electric furnaces and raw coal-fired boilers have increased a lot, and the atmospheric pollutants discharged from these furnaces are extremely harmful to the surrounding environment, so that the technology of removing particulates from dust-containing gas to reduce the discharge thereof to the atmosphere has become more and more important, and the technology of removing particulates from dust-containing gas to reduce the discharge thereof to the atmosphere has been an important measure. The dust-containing industrial waste gas is produced by mechanical processes such as crushing, sieving, conveying, blasting and the like of solid substances, or by processes such as combustion, high-temperature melting, chemical reaction and the like. The former contains dust of large particle size and the same chemical composition as the original solid material, and the latter contains dust of small particle size and of a chemical nature different from the material from which it is produced. Improved production processes and combustion techniques may reduce particulate generation. Dust collectors are widely used to control dust and fumes that have been produced.
