Description

technical field [0001] The invention relates to a dust removal system, more specifically, it relates to an electric dust removal pulse power supply. Background technique [0002] With the development of modern industry, people pay more and more attention to environmental issues, such as air pollution, water pollution, and noise pollution, especially air pollution. The dust and smog in industrial production are the chief culprits of air pollution. In order to reduce their emissions, various dust removal measures must be taken to control them. [0003] Commonly used industrial dust removal equipment is electrostatic precipitator. The electrostatic precipitator is composed of a dust removal body and a high-voltage source, and the high-voltage power supply is the focus and core of the entire electrostatic precipitator. The high-voltage power supply provides high-voltage negative electricity for the electric field of the dust collector. The gas in the electric field is ionized ...

AI Technical Summary

Problems solved by technology

However, there are many defects in the power frequency power supply: low power supply efficiency, low dust removal efficiency, spark discharge, large volume, high cost, etc.

[0006] With the improvement of national environmental protection requirements, it is more and more difficult for the power frequency power supply of electrostatic precipitator to meet the new environmental protection standards, and to completely replace the original power frequency power supply of electrostatic precipitator will cause a lot of waste of manpower and material resources
