Description

technical field

[0001] The invention relates to the field of air purification, in particular to a dust removal device, a dust removal system and a dust removal method using a triboelectric field. Background technique

[0002] At present, a large amount of dust is produced in various industrial processes, such as in factory workshops, combustion exhaust gas, etc.; in daily life, a large amount of exhaust gas, smog caused by mineral oil combustion, etc. These particles are suspended in the air and have a serious impact on human health, life and production.

[0003] At present, industrial dust removal methods mainly include electrostatic dust removal, particle bed filter dust removal, filter bag dust removal and so on. However, various dust removal methods have a series of problems, such as complex and expensive electrostatic dust removal equipment, high back pressure of particle bed filters, and troublesome dust removal during filter bag dust removal.
