A high-frequency pulse power supply for electric dust removal

Abstract

The invention relates to a high frequency pulse power supply for electric dedusting. A three-phase alternating-current power supply is supplied to a deduster electric field after passing through the high frequency pulse power supply for electric dedusting. The high frequency pulse power supply for electric dedusting includes a main loop switch, a pulse power generator, a high frequency fundamental wave circuit, a DSP controller, a detection circuit, and a coupling circuit. The pulse power generator and the high frequency fundamental wave circuit are connected between the main loop switch and the coupling circuit in parallel.

Description

technical field [0001] The invention relates to a high-voltage pulse power supply, in particular to a high-frequency pulse power supply for electric dust removal. Background technique [0002] In recent years, as the country strengthens the control of air pollution, the environmental protection emission standards of enterprises are also improving. Many industrial flue gas purification equipment cannot meet the new standards and are facing the situation of secondary transformation. At present, the main flue gas purification equipment in the market is the electrostatic precipitator. As one of the key components of the electrostatic precipitator, the power supply of the electrostatic precipitator has an important impact on the dust removal effect, energy consumption, working stability and safety. At present, the main power sources in the market are three-phase power sources and high-frequency power sources. [0003] The electrostatic precipitator is a device that uses a high-...

Problems solved by technology

In the case of no serious flashover, the above method has a better absorption effect on dust with low specific resistance, the dust absorption effect of medium specific resistance is average, and the dust absorption effect of high specific resistance is poor

Therefore, the dust removal effect of the dust collector cannot be better improved; or the dust removal energy consumption is greatly increased to improve the dust removal effect, and even the life of the dust collector is shortened.

[0005] On the other hand, from the perspective of energy consumption, in the process of electrostatic precipitation, most of the electric energy consumed by the dust removal electric field does not participate in charging the dust, but moves directly from the cathode plate to the anode plate in the form of electrons, which is equivalent to a large amount of electricity. A large amount of energy is wasted in the electric field, resulting in a low utilization rate of electric energy
