Electric field device with automatic cleaning function

Abstract

The invention discloses an electric field device with an automatic cleaning function. The electric field device comprises a support, at least one hollow cylindrical dust collecting electrode and a corona pole, wherein the corona pole is placed on the axle wire of the hollow cylindrical dust collecting electrode, and the end part of the corona pole is fixed on the support; the dust collecting electrode is grounded, and the corona pole is connected with a power source. The electric field device further comprises a wind wheel, and an internal thread is formed on the axle hole of the wind wheel. An external thread matched with the internal thread on the wind wheel is formed on the corona pole. A dust sweeping device contacting with the inner wall of the hollow cylindrical dust collecting electrode is arranged on the periphery of the wind wheel. The electric field device does not need manual cleaning, and thus the time and cost are saved.

Description

technical field [0001] The invention relates to the technical field of an electric field device in an electrostatic precipitator, and more specifically relates to an electric field device with an automatic cleaning function. Background technique [0002] In recent years, the problem of air pollution has become more and more prominent, and the control of fine particulate matter (such as PM2.5) pollutants has attracted more and more attention. Because the electrostatic precipitator has the characteristics of high dust removal efficiency, simple structure, less consumables, and low cost, it is widely used to purify waste dust and waste gas. [0003] The working principle of the electrostatic precipitator is: when the gas containing dust particles passes through the high-voltage electric field formed between the cathode wire (corona wire) connected to the high-voltage DC power supply and the grounded anode plate (dust collector), the corona occurs due to the cathode. Discharge,...
