Apparatus and system for smoke plume removal synergistic ultrafine flue dust removal of flue gas

Abstract

The invention discloses an apparatus for smoke plume removal synergistic ultrafine flue dust removal of flue gas. The apparatus comprises a smoke plume removal unit and a sound wave generating unit coupled to the smoke plume removal unit, wherein the sound wave generating unit is arranged in the flue gas phase change zone in the smoke plume removal unit. The traditional dust removal technology cannot effectively control the emission of submicron flue dust, the sound wave can effectively promote the agglomeration of the submicron soot so as to increase the size, and then the effective removal can be achieved through defogging or dust removal; and the agglomeration by the single use of sound wave has disadvantages of high energy consumption and high sound wave noise, and the single use of phase change agglomeration removal has disadvantages of high engineering construction cost and low flue dust removal efficiency. According to the present invention, the problems in the prior art can bewell solved by using the smoke plume removal synergistic ultrafine flue dust agglomeration removal apparatus and the smoke plume removal synergistic ultrafine flue dust agglomeration removal system soas to effectively remove submicron ultrafine flue dust.

Description

technical field [0001] The invention relates to the technical field of environmental protection treatment of boiler flue gas, and more specifically, relates to a device and system for flue gas dewhitening and superfine soot removal. Background technique [0002] For the control technology of particulate matter emission in thermal power plants, electrostatic precipitators are still the main technology at present, and wet flue gas desulfurization devices are installed downstream of them. Coal-fired power plants with high-efficiency electrostatic precipitators (ESP) or bag filters can control the particle size of the emitted particles well within PM10. Wet flue gas desulfurization (WFGD) scrubbers can also capture particulate matter (about 75% dust removal efficiency), which can control the particle size to within PM3.5, most of which are PM1. Combined use of ESP and WFGD can make the dust removal rate reach 99.99%. Whether it is a dust collector or a WFGD system, it has a hi...

Problems solved by technology

However, the net flue gas after wet desulfurization has low temperature and high humidity, and it is easy to produce "white smoke" when discharged into the atmosphere through the chimney. The high-humidity flue gas hinders the diffusion of flue gas in the atmosphere, and the high-humidity flue gas The moisture in the water combines with the primary pollutants around the power plant and converts them into secondary pollutants, which aggravates the environmental pollution around the power plant
