Novel efficient wet type electrical precipitator based on pulse power supply

Abstract

The invention provides a novel efficient wet type electrical precipitator based on a pulse power supply. The wet type electrical precipitator comprises an orthohexagonal cellular conductive glass fiber reinforced plastics anode tube, a titanium electrode discharge wire and a high voltage pulse power supply device, wherein the output end of the high voltage pulse power supply device is connected to the titanium electrode discharge wire, the high voltage pulse power supply is input to the titanium electrode discharge wire, the high voltage pulse power supply is a high voltage power supply integrated by a base voltage overlapped pulse voltage, and the titanium electrode discharge wire is positioned in the center of the anode tube. By applying the overlapped voltage and the titanium electrode discharge wire to the wet type electrical precipitator, the dust removal efficiency is improved as a result of a reasonable structural design of the titanium electrode discharge wire and the anode tube. The wet type electrical precipitator can reduce particulate matter emission by over 95%, can reduce over 90% of SO3 emission and can remarkably reduce the turbidity of visible smoke emitted by a wet chimney, and has perspectiveness of mercury removal. The technical problem that smoke particulates are emitted by reaching the standard or are emitted in an ultralow manner is effectively solved, so that the investment cost is lowered, and the land is saved.

Description

technical field [0001] The invention relates to a wet electrostatic precipitator, specifically a new high-efficiency wet electrostatic precipitator based on pulse power supply Background technique [0002] Wet electrostatic precipitator technology is relatively mature in developed countries such as the United States, Europe, and Japan. It has nearly 30 years of application experience in coal-fired power plants, and nearly a hundred sets of different types of WESP have been successfully operated on large-scale units in power plants. [0003] Japan's wet electrostatic precipitator technology started earlier and has a history of more than 30 years of application. Mitsubishi Heavy Industries alone has 33 sets of equipment used in power plants. Since the 5 sets of wet electrostatic precipitators in Binan Power Plant in Japan have been put into operation for 20 years, the emission concentration of smoke and dust has been maintained at a level of 2-5mg / m3 for a long time, and the b...

Problems solved by technology

[0013] In order to solve the traditional high-voltage DC power supply limited by power and electric field flashover, the peak value of the electric field voltage of the electrostatic precipitator cannot meet the dust removal requirements for dust below PM2.5
