Device for removing fine particles by combining acoustic agglomeration technology with turbulence coalescence technology and method thereof

Abstract

The invention discloses a device for removing fine particles by acoustic wave agglomeration combined with turbulent flow coalescing technology and a method thereof, which belong to the field of pollutant removal equipment and removal technology. Reunion chamber, compression drive sound source, turbulence cylinder, flue gas inlet pipe and flue gas outlet pipe; the flue gas inlet pipe, sound wave reunion chamber, flue gas outlet pipe and dust collector are connected in series; the outer roof of the sound wave reunion chamber There are single or multiple compression driving sound sources on the surface; a turbulence cylinder is arranged horizontally inside the sound wave reunion chamber. The turbulence cylinder is cylindrical and arranged in an array, and its function is to generate turbulent flow. The present invention adopts sound wave agglomeration combined with turbulent flow agglomeration technology to pretreat the fine particles in the dusty flue gas discharged from coal-fired power plants, etc., agglomerates the fine particles into larger particles, and combines the follow-up conventional dust collector to achieve high-efficiency removal of PM 2.5 purpose, thereby controlling the PM 2.5 emissions.

Description

technical field [0001] The invention belongs to the field of pollutant removal equipment and removal technology, and in particular relates to a device and method for removing fine particles through acoustic wave agglomeration combined with turbulent flow agglomeration technology. Background technique [0002] my country's energy structure is dominated by coal, but coal and other fossil fuels will emit a large amount of particulate matter during the combustion process, among which PM is the most harmful 2.5 . Some studies have found that PM 2.5 It is one of the main pollutants that have the greatest impact on human health, mainly causing chronic diseases, respiratory diseases, and cardiovascular and cerebrovascular diseases. [0003] At present, coal-fired power plants in my country generally use electrostatic precipitators, and their removal efficiency for large particles can reach 99.9%, but they cannot effectively remove fine particles. Therefore, coal-fired power plants...

AI Technical Summary

Problems solved by technology

[0003] At present, coal-fired power plants in my country generally use electrostatic precipitators, and their removal efficiency for large particles can reach 99.9%, but they cannot effectively remove fine particles. Therefore, coal-fired power plants are considered PM 2.5 largest source of emissions

Existing dust removal equipment, including bag filter, electrostatic precipitator, wet electrostatic precipitator, etc. 2.5 The removal efficiency is low and cannot meet the increasingly stringent environmental protection requirements

[0004] The general sonic agglomeration technology has limited agglomeration efficiency for fine particles. To further improve the agglomeration efficiency, it is necessary to increase the sound pressure level, increase energy consumption and increase noise pollution.
