Dry type electrostatic dust collector

Abstract

The invention discloses a dry type electrostatic dust collector. The dry type electrostatic dust collector comprises a shell body, wherein the shell body is internally provided with a discharging electrode and dust collection electrodes located at the two sides of the discharging electrode; the shell body is internally provided with a discharging electrode vibration device and a dust collection electrode vibration device, and is also internally provided with a spiral conveyor located under the dust collection electrodes and the discharging electrode; an ash collection cabin communicated with the inner cavity of the shell body is arranged on the outer side wall of the shell body; the discharging electrode is composed of a carbon steel layer, a carbon fiber glass fiber reinforced plastic layer and a carbon fiber membrane; the carbon steel layer is covered by the carbon fiber glass fiber reinforced plastic layer; and the carbon fiber glass fiber reinforced plastic layer is covered by the carbon fiber membrane. According to the dry type electrostatic dust collector, the corrosion resisting performance of the discharging electrode is good and the whole service life of the dry type electrostatic dust collector is ensured.

Description

Technical field [0001] The invention relates to a dry electrostatic precipitator. Background technique [0002] The smoke and dust emitted by industrial production in modern society seriously pollutes the atmosphere and affects human health. Therefore, countries have formulated more and more stringent emission standards to protect the environment. Various dust removal equipment are also widely used in various fields of dust emission control in. The electrostatic precipitator is an efficient dust removal equipment. Its principle is to use high-voltage electricity to make the electrodes generate corona discharge, release free electrons and ions, and charge the dust particles. The charged dust is separated from the airflow under the action of the electric field. The polar plates or polar lines of opposite sex move. When the charged dust reaches the polar plates or polar lines, the electrostatic force is adsorbed on the polar plates or polar lines, and the dust falls into the ash bu...

Problems solved by technology

[0003] However, as the discharge part of the electrostatic precipitator, the quality of the cathode directly affects the dust removal effect

Due to the long-term corrosive working environment and complex working conditions, the cathode wire of the existing electrostatic precipitator is generally made of carbon steel. This material is relatively low in cost but has poor corrosion resistance. After a period of operation, the surface will corrode. , so as to break, and at the same time, the medium is easy to absorb on the surface of the cathode wire after corrosion, and is not easy to be shaken off, so that it accumulates until the cathode hypertrophy affects the discharge effect, thereby directly reducing the dust removal efficiency
