Abstract

The invention relates to a circulating frictional electrostatic precipitation device which comprises a first electrostatic precipitation chamber, a second electrostatic precipitation chamber, a frictional electrifier, a centrifugal fan, a first single-pole double-throw switch, a second single-pole double-throw switch and the like. By means of the cooperative frictional electrification of the specially designed frictional electrifier and a fan impeller, the circulating frictional electrostatic precipitation device increases the efficiency of frictional electrification; by adjusting valves, theratio of circulating gas volume to gas treatment capacity can be controlled, consequently, the residence time of dusty gas stays in the device is regulated, the intensity of electrification is regulated, and thereby the dust precipitation efficiency of the device is controlled; the continuous operation of the device is ensured by two electrostatic precipitators; compared with the energy consumption of electric field electrification, the energy consumption is low.

Description

technical field [0001] The invention relates to the field of gas dust removal, in particular to a circulating friction electrostatic dust removal device. Background technique [0002] In recent years, with the rapid development of the economy, metallurgical steelmaking electric furnaces and boilers fueled by raw coal have increased a lot. The air pollutants emitted by these furnaces have caused great harm to the surrounding environment. Therefore, removing particulate matter from the dusty gas to reduce Atmospheric particulate matter pollution has become an urgent technical problem to be solved. [0003] The capture of particulate matter in gas can be divided into mechanical dust removal, electrostatic dust removal, filter dust removal and washing dust removal according to the mechanism. Among them, the electrostatic dust removal technology has the following advantages: (1) high dust removal efficiency; (2) can purify a large amount of air; (3) the particle size range that ...
