Sound wave agglomeration dust removal system

Abstract

A sound wave agglomeration dust removal system comprises acoustic wave dust removers and a demister, and the acoustic wave dust removers are symmetrically arranged on two sides of a flue gas channel of a desulfurization tower, the demister is arranged in a matrix arrangement manner and connected with the flue gas outlet of the flue gas channel of the desulfurization tower. The small-particle fluedust is discharged into the flue gas channel through the desulfurization tower, and then high-sound-pressure-level low-frequency sound waves are emitted into the flue gas channel through the acousticwave dust removers, so that the large vibration of the small-particle flue dust in the flue gas channel is caused and mutual friction collide between the small particle flue dust can be formed, and because the humidity of the flue gas is large, the small-particle flue dust generates an agglomeration effect in the mutual friction collision process, and the small-particle flue dust rapidly grows into large-particle flue dust under the effect. Then, the large-particle flue dust is adsorbed by the demister and washed away and discharged into the atmosphere, furthermore the small-particle dust canbe effectively removed, the content of PM2.5 dust particles in the flue gas can be reduced, and the atmospheric pollution can be reduced.

Description

technical field [0001] The invention relates to the technical field of pollution control equipment manufacturing, in particular to an acoustic wave agglomeration dust removal system. Background technique [0002] With the progress of the society and the development of the economy, the pollutant discharge in the flue gas of coal-fired boilers in thermal power plants, iron and steel, coal chemical industry, building materials and other related fields, and the pollution of the atmospheric environment have been widely concerned by people, so the pollution can be effectively reduced It is a severe challenge for the sustainable development of my country's energy sector to improve its impact on the environment. [0003] At present, electrostatic precipitators are generally used in the industry to deal with exhaust smoke, but electrostatic precipitators can only adsorb large particles of smoke, but the removal efficiency of micron and submicron particles is very low, especially for P...

Problems solved by technology

[0003] At present, electrostatic precipitators are generally used in the industry to deal with exhaust smoke, but electrostatic precipitators can only adsorb large particles of smoke, but the removal efficiency of micron and submicron particles is very low, especially for PM2.5 The adsorption of particulate dust is not strong, resulting in a high content of PM2.5 dust particles in the chimney exhaust of industrial production, which is discharged into the atmosphere and causes pollution
