[0018] The preferred embodiments of the present application will be described in detail in conjunction with the accompanying drawings.

[0019] A rotary valve for air intake and water discharge is connected to a box body, as shown in Figures 1 to 4 , comprising a rotary inner sleeve 1 and a water discharge outer sleeve 2.

[0020] The rotary inner sleeve 1 is provided with a water return inner hole 101, a water outlet inner hole 102 and a steam inlet hole 103. The water return inner hole 101 is arranged on the end face of the rotary inner sleeve 1, the water outlet inner hole 102 is arranged on the side face of the rotary inner sleeve 1, the water return inner hole 101 and the water outlet inner hole 102 are communicated, the rotary inner sleeve 1 is fixedly connected with the box body, and the water return inner hole 101 and the steam inlet hole 103 of the rotary inner sleeve 1 are respectively communicated with the inner cavity of the box body. The steam inlet hole 103 is communicated with the air inlet hole of the box body, the water return inner hole 101 is communicated with the water outlet hole of the box body, and after high-temperature steam enters the box body, its heat is absorbed and then discharged from the water outlet hole of the box body.

[0021] The drain jacket 2 is arranged outside the rotating inner jacket 1, and the drain jacket 2 and the rotating inner jacket 1 are arranged in rotation, and the drain jacket 2 and the rotating inner jacket 1 form an annular inner cavity 12, the water outlet inner hole 102 is communicated with the annular inner cavity 12, and the side surface of the drain jacket 2 is provided with a drain outer hole 201 communicated with the annular inner cavity 12. Regarding the shape of the annular inner cavity 12, two ways are provided in the application. One is that the inner side surface of the drain jacket 2 is provided with an annular inner groove; the other is that the outer side surface of the rotating inner jacket 1 is provided with an annular inner groove. The drain outer hole 201 is communicated with the annular inner cavity 12, and the drain outer hole 201 is circumscribed by a drain pipeline. In order to facilitate the discharge of the condensed water flowing out of the drain outer hole 201, the drain outer hole 201 is vertically downward. The drain jacket 2 is fixedly arranged on the ground, and the rotating inner jacket 1 is arranged in rotation with the drain jacket 2. In order to ensure the sealing performance of the drain jacket 2 and the rotating inner jacket 1, a sealing ring 3 is arranged at the joint of the rotating inner jacket 1 and the drain jacket 2.

[0022] In use, the condensed water drainage system is installed on the box body, as shown in Figure 5 and Figure 6 , high-temperature steam enters the box body through the steam inlet hole 103, and when the steam heat is dissipated, it becomes condensed water, enters the rotating inner jacket 1 from the water return inner hole 101, and then flows out through the water outlet inner hole 102. Under the action of the annular inner cavity 12, the condensed water flows out of the drain outer hole 201.
