Abstract

The invention discloses a differential electric precipitator, which comprises a shell, an ash bucket, an inlet seal head, an outlet seal head, a cathode system and an anode system. The ash bucket is connected with the shell through a bottom beam and is arranged below the shell, the inlet seal head and the outlet seal head are respectively arranged on the two sides of the shell, the cathode system and the anode system are arranged in the shell, and an auxiliary discharge system is arranged on the rear end of the inlet seal head, the anode system comprises a plurality of through type anodes for fume to transversely penetrate through, each two through type anodes form a wedge shape from the inlet seal head side to the outlet seal head side, and the contacts of the through type anodes on the inlet seal head side are connected via a V-shaped deflector; and the cathode system consists of a plurality of small cathode frameworks, and each small framework is independently hanged in an insulating way and is arranged in a triangular space between the anode system and the auxiliary anode discharge system. The invention reduces the average distance between dust and the anode plate, avoids the anti-corona scene caused by the dust with high specific resistance, improves the ash cleaning effect, and prevents the secondary dust.

Description

technical field

[0001] The invention relates to a dust control device, in particular to a differential electrostatic precipitator. Background technique

[0002] With the continuous improvement of the degree of industrialization, the environmental pollution in the world is increasing day by day, and the improvement and protection of the environment have been paid more and more attention by people from all walks of life. To this end, China has continuously improved the emission standards of smoke and dust, from the initial 80mg / m 3 Gradually drop to 30-50mg / m 3 Even below, dust removal systems in various industries such as electric power, building materials, steel, and non-ferrous smelting are facing an unprecedented test, and the following situations have occurred:

[0003] 1. Electric power industry: As coal resources decrease year by year, the quality of coal used in boilers also decreases, resulting in a large increase in smoke and dust content, and the specific resistan...
