Acoustic agglomeration system and method based on multi-stage reflective focused acoustic waveguide array structure

Abstract

The invention discloses an acoustic wave agglomeration system and an acoustic wave agglomeration method based on a multi-stage reflective focusing acoustic waveguide array structure. The system comprises an air flow sound source, a horn, reflective focusing acoustic waveguide arrays, a smoke dust pipeline and the like, wherein reflective focusing acoustic waveguides form a certain quantity of arrays; the arrays are connected and communicated with the air flow sound source, the horn and a dust-containing smoke pipeline, so that the sound pressure level of the reflective focusing acoustic waveguide arrays and an acoustic wave action chamber reaches a certain intensity level (larger than 155dB); an excited flow is vibrated by suspended particles of the reflective focusing acoustic waveguide arrays and the acoustic wave action chamber to generate a relative speed so as to mutual impact to agglomerate aggregates which are relatively large in particle size or large particles; the suspended large particles are removed by adopting a general dust removal technique so as to realize the aim of controlling emission of PM2.5. The system disclosed by the invention has the advantages of being simple in structure and capable of effectively removing the suspended particles.

Description

technical field [0001] The invention relates to the technical field of dust removal, in particular to an acoustic wave agglomeration system based on a multi-stage reflective focused acoustic waveguide array structure. Background technique [0002] With the rapid development of my country's national economy and the massive consumption of fossil fuels, PM2.5 has become the main pollutant that pollutes the air environment in my country's urban areas, which has aroused close attention and deep concern. Suspended fine particles are rich in a variety of toxic trace substances, and they are transported in the atmosphere for a long distance and for a long time, which is likely to have a serious impact on the human body and the environment. [0003] At present, dry dust removal technology is widely used in industry, such as conventional removal technology such as cyclone separation. Although the removal efficiency of these conventional dust removal technologies for removing suspended...

Suspended fine particles are rich in a variety of toxic trace substances and are transported in the atmosphere for a long distance and for a long time, which is likely to have a serious impact on the human body and the environment

[0003] At present, dry dust removal technology is widely used in industry, such as conventional removal technology such as cyclone separation. Although the removal efficiency of these conventional dust removal technologies for removing suspended coarse particles (>10 μm) is very high, but for suspended fine particles (<2.5 μm) The removal efficiency is very low
