Therefore, gas-water separation is generally performed first during exhaust, and then silencing is performed. Since a cyclone gas-water separator is used for gas-water separation, a lot of noise is generated during the water separation process, resulting in an unsatisfactory overall silencing effect.

[0022] When the water vapor separation silencer is used, water vapor enters from the air intake pipe body 110, and the water vapor is initially separated by the multiple holes on the air intake pipe body 110, so that the heavier water is directly discharged through the drain pipe 102, and the water vapor rises and first passes through the first-level condensation coil 103 for cooling, so that the water in the air flow is condensed for the first time, and a part of the condensed water droplets will adhere to the inner surface wall of the inner cylinder 108 and the lower end of the second supporting fixing plate 113, and then flow along the inner surface wall of the inner cylinder 108 to the base 101, the airflow after the first cooling flows through the shrink tube body 112, the expanded airflow is compressed, the flow rate will increase to a certain extent, and the airflow temperature will be further reduced, and the airflow after passing through the shrink tube body 112 passes through the secondary condensing coil 104 for secondary cooling, further accelerating the condensation of gaseous water carried by the airflow, and the condensed water droplets here will adhere to the inner surface wall of the inner cylinder 108 and the lower end of the third supporting fixed plate 116, and then flow to the upper end of the second supporting fixed plate 113 to gather, and the gathered liquid water will be The air flows through the first water pipe 114 to the base 101 for drainage.
