Problems solved by technology

On the other hand, in CN201210115860.0, sound waves in the ultrasonic frequency band are used for dust removal. In industrial application environments, the propagation attenuation of ultrasonic waves is relatively significant, and the intensity and effect of sound waves in the action space cannot be guaranteed.
[0004] Therefore, none of the above patents can effectively solve the problems of limited field space and economical use in industrial application scenarios at the same time

Abstract

The invention provides an acoustic wave emission reducing device for PM2.5 particulate matters in industrial flue gas. Cross section of an acoustic wave agglomeration chamber is partitioned to form clustered flue gas pipelines in annular arrangement through radial central partitions. Through acoustic conduction structure between the central partitions and the inner wall of the acoustic wave agglomeration chamber, one or multiple strong acoustic wave excitation is applied in the middle of each clustered flue gas pipeline, and excitation direction is perpendicular to flowing direction of the flue gas in the corresponding pipeline. By adding smoke-incoming acoustic blocking structure and gas-blocking acoustic penetrating structure at inlets, outlets and acoustic transmission positions of the clustered flue gas pipelines and matching with axial size of the flue gas pipelines in integer multiples of half wavelength, sufficient action of high-intensity acoustic waves at specific frequency and particulate matters in the flue gas is completed in each pipeline. The acoustic wave emission reducing device is compact in structure and realizes acoustic wave agglomeration of fine particulate matters for emission reducing with high efficiency and low energy consumption.

Description

technical field [0001] The invention relates to the technical field of acoustic dust removal, in particular to an acoustic agglomeration chamber for PM2.5 particles in industrial flue gas and an emission reduction device thereof. Background technique [0002] Fine particulate matter, mainly PM2.5, has become the main pollutant in my country's urban air environment. Acoustic agglomeration and emission reduction refers to the interaction between strong sound waves and particulate matter in flue gas to increase the particle size of fine particles in flue gas, thereby significantly enhancing the removal efficiency of conventional dust removal equipment for fine particles. As a non-contact emission reduction method, the acoustic agglomeration method has short action time, significant effect, economical and easy to use, and can adapt to high temperature, high pressure and corrosive environments. It is a special technology for reducing fine particulate matter from pollution sources...
