The condensing structure 210 is typically sprayed with flowing cold water to exchange heat between the hot and humid air in the condensing duct 220 and the condensing structure 210, so that moisture in the hot and humid air is condensed on the condensing structure 210, and the hot and humid air is converted into dry and cold air.

Because the volute 112 and the condensing structure 210 are arranged at intervals, the first flange 114 is formed by extending towards the barrel 200 at the edge of the second air inlet 113, so that the first flange 114 is arranged in the first air inlet 230 in a penetrating manner, air in the condensing air duct can flow into the volute air cavity 10b through a channel formed by encircling the first flange, and air leakage can be effectively avoided by arranging the second sealing piece 40 between the first flange 114 and the first air inlet 230.
