[0031] The separation cylinder 5 is detachably connected to the gas delivery pipe 2 , so that the gas entering the separation cylinder 5 can be discharged into the exhaust pipe 3 , thereby discharging the gas separated from the water vapor out of the shell 1 , and the separation cylinder 5 can be easily removed from the top cover 102 .

[0032] In this embodiment, the bottom of the separation cylinder 5 is an open structure.

[0033] The water vapor separation mechanism 6 is fixedly arranged inside the separation cylinder 5 through a fixing frame. The water vapor separation mechanism 6 includes a guide tube 601, a gas guide cover 602 and a liquid guide cover 603 fixedly arranged on the outside of the guide tube 601, and a gas flow area 604 is formed between the liquid guide cover 603 and the gas guide cover 602. In this embodiment, the gas guide cover 602 is arranged above the liquid guide cover 603. Through the water vapor separation mechanism 6, the gas entering the shell 1 can be guided, so that the gas can be better circulated in the shell 1, and it is more conducive to the gas to fully contact with the gas guide cover 602 and the liquid guide cover 603, thereby helping to increase the effect of separating water vapor in the gas.

[0034] The first exhaust groove 605 is arranged on the side wall of the guide tube 601 and is arranged corresponding to the gas circulation area 604. In the present embodiment, a plurality of first exhaust grooves 605 are arranged, and the plurality of first exhaust grooves 605 are circumferentially distributed on the side wall of the guide tube 601.
