Abstract

The invention provides a high-voltage pulse power supply for an electrostatic dust collector, the power supply supplies power to an electrostatic dust collection load body, charges a capacitor after voltage regulation, boosting and rectification of a three-phase power supply, generates resonance with the primary side of a transformer through the capacitor, and generates high-voltage pulse under the control of an electronic switch IGBT. According to the invention, the problem of back corona easily caused by low peak power of a power supply in the prior art is solved, the peak power of the dustremover is improved, the dust driving speed is increased, the phenomenon of partial back discharge of a dust layer is eliminated, the back corona is avoided, the purposes of saving energy and improving the dust removal efficiency are achieved, and high social and economic values are realized.

Description

technical field [0001] The invention belongs to the technical field of power supplies, and in particular relates to a high-voltage pulse power supply for electrostatic precipitators, which is suitable for electrostatic precipitators in the fields of energy and chemical industry. Background technique [0002] The electrostatic precipitator uses the strong electric field applied in the body to ionize the gas, that is, to generate corona discharge, and then charge the dust particles, and under the action of the electric field force, the dust particles are separated from the gas and captured Dust removal device. The dust removal efficiency of the electrostatic precipitator depends on the driving speed of the dust, and the driving speed of the dust is proportional to the peak corona power. It can be seen that to improve the dust removal efficiency, the corona peak power of the dust collector should be increased as much as possible. The charged dust in the electrostatic precipita...
