In addition, each time the tail gas of the diesel engine passes through the primary expansion cavity 3, the air flow with high-intensity noise is subjected to rotational flow and expansion to reduce noise. The noise-reduced air flow is compressed by the continuous high-pressure air inlet and then enters the cyclone expansion cavity of the next stage, and the noise is continuously reduced, so that the noise of the tail gas of the diesel engine is effectively reduced through multistage cyclone expansion, compression and cyclone expansion treatment.
