Technical Field

[0001] The utility model relates to the technical field of dust removal devices, in particular to a chemical environmental protection dust removal device for safety engineering. Background Art

[0002] A dust collector is a device used to capture and separate dust particles suspended in the air or gas. In the production and manufacturing of metallurgy, casting, cement building materials, machinery, light industry, electricity, etc., it is necessary to eliminate dust pollution, protect the environment, and improve working conditions. In the pharmaceutical manufacturing process of pharmaceutical chemical plants, since the dust in pharmaceutical plants is usually flammable, in order to improve people's safety, dust removal is required. At the same time, dust removal can also avoid dust pollution of the surrounding environment and achieve the purpose of environmental protection. At present, the exhaust gas discharged is treated with dust collectors, and the current dust removal method of dust removal devices is relatively single, resulting in low efficiency in removing dust from the gas, and it is inconvenient to disassemble and replace the dust removal structure.
