A triboelectric dust removal device, dust removal system and dust removal method

Abstract

The invention discloses a friction electric dust removing device and a dust removing method, the friction electric dust removing device includes an outer layer casing and an inner layer casing which are in a jacket layer structure, the outer layer casing is a sealing structure, is provided with a liquid discharge port at the bottom; the inner layer casing is provided with a plurality of gas guide holes, the inner wall of the inner layer casing is provided with electrodes, a plurality of dust collection units are arranged in the inner layer casing, surface materials of part of or all of the dust collection units are different in electronegativity from materials of the electrodes, a spray head is introduced from the outer layer casing, is controlled by a liquid inlet switch, and is used for cleaning the dust collection units or the electrodes; the inner layer casing rotates to enable the dust collection units or the electrodes to mutually collide to form an electrostatic field, a gas entering from a gas inlet in turn passes through the dust collection units, a gap between the outer layer casing and the inner layer casing, the dust collection units and a gas outlet for filtration of particles in the gas. The spray head can automatically clean the dust collection units and the electrodes in the dust removing device, and prolong the service life of the device.

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. Contents of the invent...
