Prevent dust collector of jam
The invention relates to the technical field of dust removal, in particular to an anti-blocking dust removal device.
In recent years, with rapid development of economy, metallurgical steelmaking electric furnaces and raw coal-fueled boilers have increased, and air pollutants discharged from these furnaces pose great harm to the surrounding environment, so that a technology for removing particles from dust-containing gas to reduce the emission thereof to the atmosphere has become important, and dust-containing industrial waste gas or gas is generated from mechanical processes such as pulverization, screening, transportation, blasting, etc. of solid substances, or from processes such as combustion, high-temperature melting, and chemical reactions. The former contains dust with large particle size and chemical composition the same as the original solid matter, and the latter contains dust with small particle size and chemical property different from that of the substance to be generated. Improvements in production processes and combustion techniques can reduce particulate generation. Dust collectors are widely used to control dust and fumes that have been generated; in the dust removal process, the filter cover is easy to block, so that the normal flow of waste gas is influenced, and the dust removal efficiency is reduced.
