Then, at least two partition plates 20, a first cover plate 111 and a second cover plate 112 are welded to the connecting body 113, and then the sound-proof sleeve 50 is sleeved outside the connecting body 113. And finally, welding an air inlet pipe 63 and an air outlet pipe 61, arranging a third cover plate 62 in the air outlet pipe 61, communicating the booster pump 74 with the water inlet pipe 71, and sequentially communicating the drain hole 23, the cooling tower 73 and the booster pump 74 through water pipes.
When the silencer provided by the embodiment of the disclosure works, the booster pump 74 is started first, then the generator is started, the gas enters the cavity 12 and collides with the partition plate 20 to change the direction, and the gas flow is impacted reversely, so that the gas flow speed is reduced and the noise is counteracted. The gas again changes direction and diffuses into the isolation chamber 120 as it passes through the muffler 30, reducing velocity and noise. Meanwhile, water sprayed by the spray header 72 is mixed with the gas to generate steam, so that the gas flow is cooled and washed. In addition, the sound-deadening sleeve 40 and the soundproof sleeve 50 can absorb noise and also can reduce the transmission of noise.
The above description is intended to be exemplary only and not to limit the present disclosure, and any modification, equivalent replacement, or improvement made without departing from the spirit and scope of the present disclosure is to be considered as the same as the present disclosure.
