Abstract
The invention relates to an industrial-grade acoustic agglomeration PM2.5 emission reduction system with high efficiency and low energy consumption. The system comprises an airflow sound source, a focusing device and an agglomeration cabin connected with the focusing device. The airflow sound source converts high-pressure airflow energy to strong acoustic wave. The focusing device comprises a horn and a coupling cabin. A lens is arranged between the horn and the coupling cabin. The horn is connected to the airflow sound source. The horn radiates strong acoustic wave energy emitted from the airflow sound source; the acoustic wave energy is converged through the lens and the converged acoustic wave energy passes through the coupling cabin to form a plane standing wave field in the agglomeration cabin. Smoke flows into the agglomeration cabin through an air inlet at the front end of the agglomeration cabin, and flows out of an air outlet at the rear end of the agglomeration cabin after undergoing strong acoustic wave. Small suspended particles in the smoke are aggregated to form large-size aggregates. By the use of the industrial-grade acoustic agglomeration PM2.5 emission reduction system with high efficiency and low energy consumption, the problem that emission reduction efficiency and energy consumption cannot be both considered by an industrial-grade fine particle acoustic agglomeration emission reduction system based on an airflow sound source is solved.
