High-pressure electrostatic dust collection electric field device of coal-fired unit for generating ozone and simultaneously desulfurizing and denitrating

Abstract

The invention discloses a high-pressure electrostatic dust collection electric field device of a coal-fired unit for generating ozone and simultaneously desulfurizing and denitrating. The device comprises an electrostatic dust collection channel which is formed by sequentially connecting a plurality of electric fields, a neutralizing tower, a water mist spray system, a water supply device, a power control system, a spray control system and an intelligent closed-loop control system, wherein the flashover frequency of the power control system is set to be 150-10000 times / minute, the water mist spray system is arranged in the neutralizing tower, the intelligent closed-loop control system is utilized to control the power control system and the spray control system is utilized to automatically coordinated with each other, so that the high-pressure electrostatic dust collection device can be added with a denitrating function on the basis of maintaining the original electrostatic dust collecting and desulfurizing functions, and nearly no investment is required for obtaining the denitrating function. On the basis of reasonably utilizing the original equipment, the environmental protection emission requirements are satisfied, and the device has the advantages of low cost, high operation effect and obvious integral economic benefit.

Description

technical field [0001] The invention belongs to the technical field of high-voltage electrostatic dust removal, and in particular relates to a high-voltage electrostatic dust removal electric field of a coal-fired unit to generate ozone and desulfurize and denitrify simultaneously. Background technique [0002] Since a large amount of flue gas and fly ash are inevitably produced in industrial production, and the flue gas also contains a large amount of fine particle dust, if these fly ash and dust are directly discharged into the environment, it will cause serious environmental pollution, not only It will cause different degrees of damage to the ecological environment, and it will also bring harm to people's health. Therefore, governments of various countries have formulated quite strict governance standards, requiring enterprises to deal with dust. [0003] High-voltage electrostatic dust removal is a commonly used method of gas dust removal. The dust-containing gas is ele...
