Abstract

A DC composite pulse high voltage power supply for an electrostatic precipitator comprises a pulse high voltage power supply, a DC high voltage power supply and a composite circuit. Output of the pulse high voltage power supply is coupled with the composite circuit; output of the DC high voltage power supply is coupled with the composite circuit; and output of the composite circuit is connected with the electrostatic precipitator. The pulse high voltage power supply provided by the invention is treated with voltage regulation, voltage boost and rectification by a three-phase power supply; andthe high voltage pulse is generated under the control of an electronic switch through the primary resonance of capacitor and transformer. The invention solves the problem that low peak voltage and average value voltage of the precipitator easily lead to back corona in the prior power supply technology. According to the invention, the DC high voltage and pulse high voltage are combined together toform the composite pulse voltage, so as to increase the peak voltage of the precipitator, accelerate the driving velocity of dust, prevent the occurrence of back corona, realize energy saving and improve dust collection efficiency; besides, the invention has good social and economic benefits.

Description

technical field [0001] The invention relates to a DC composite pulse high-voltage power supply for electrostatic dust removal, which is a special DC composite pulse high-voltage power supply for electrostatic dust removal of chemical environmental protection equipment in the field of 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 average value of the corona current, and also proportional to the peak value and the average value of the secondary voltage. It can be seen that to improve the dust removal efficiency shou...
