Dust collection device, system and method of frictional electricity

Abstract

The invention discloses a dust collection device and method of frictional electricity. According to the dust collection device, an outer layer shell body and an inner layer shell body of a suit layer structure are adopted, wherein the outer layer shell body is of leakproof structure, multiple gas ports are formed in the inner layer shell body, and the inner wall of the inner layer shell body is provided with electrodes; the rotation of the inner layer shell body makes multiple dust collection units and the electrodes, which are arranged in the inner layer shell body, collide with one another, gases entering through an air inlet pass through the dust collection units, a gap between the inner layer shell body and the outer layer shell body, the dust collection units and an air outlet sequentially, and under the roles of electrostatic adsorption and physical filtration of the dust collection units, effective filtration of particulate matter in the air is achieved. Through the arrangement of the inner layer shell body and the outer layer shell body, the gases are capable of passing through the dust collection device more smoothly, and airflow resistance is reduced. The dust collection device can conduct effective and fast filtration on the particulate matter with grades of micron, sub-micron, nanometer and the like.

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.
