The gas guiding upper partition plate 32 extends vertically downward from the top of the box 31, and the gas guiding lower partition plate 33 extends vertically upward. The gas guiding upper partition plate 32 and the gas guiding lower partition plate 33 are arranged in the box 31 by the buckle mechanism 40. The box 31 is provided with the water permeable plate 38 connected with the gas guiding lower partition plate 33 near the bottom of the box 31, and the water permeable plate 38 extends horizontally. There is a certain interval between the gas guiding upper partition plate 32 and the bottom of the box 31, and between the gas guiding lower partition plate 33 and the top of the box 31. The spray pipe 35 is two arranged side by side along the gas flow direction of the gas flow channel 36 in the box 31. The water return pipe 350 of the latter spray pipe 35 is connected with the water inlet pipe 351 of the former spray pipe 35, and the circulation pump 37 is arranged between the two. Each spray pipe 35 extends along the gas flow direction of the box, and the adjacent two spray pipes 35 are arranged in front of and behind each other, so that the whole is arranged at the entire top of the box 31. The water inlet pipe 351 of the last spray pipe 35 in the gas flow direction of the box 31 is provided with the pumping pump 39.

[0029] In specific implementation, the number of the gas guiding upper partition plate 32 and the gas guiding lower partition plate 33 is not limited by this embodiment, and they can also be multiple, as long as they can ensure that the gas entering the box 31 from the air inlet duct 10 runs up and down alternately in the box 31. The number of the spray pipe 35 is also not limited by this embodiment, and it can be two, three or more. The water return pipe 350 of the latter spray pipe 35 is connected with the water inlet pipe 351 of the former spray pipe 35 along the gas flow direction of the box 31, and the circulation pump 37 is arranged between the two. The water inlet pipe 351 of the last spray pipe 35 is provided with the pumping pump 39.

[0030] The air inlet duct 10 is also connected with the gas-water separator 50 to discharge the water vapor in the gas discharged from the heat exchange device 30, and then supply the air source heat pump 90 with the air.

[0033] As can be seen from the above, during installation, the insert 43 on one side of the upper partition 32 is inserted into the slot 42. During insertion, the locking block 46 contacts the inclined part of the wedge block 45. Through the provided return spring 47, the wedge block 45 and the sliding plate 44 can be squeezed to continuously slide inward. When it needs to be pulled out when it is inserted to the innermost side, the vertical part of the locking block 46 contacts the vertical part of the wedge block 45, thereby locking and fixing the insert 43. At the same time, the provided limiting plate 48 cooperates with it, thereby realizing the control of the air guide. The upper baffle 32 can be quickly fixed and installed. The same method can be used to quickly fix and install the upper baffle 32 and the lower baffle 33 of the air guide inside the housing 31, so that multiple serpentine gas flow channels 36 can be set as needed. When it needs to be disassembled, pull the actuating plate 491. The actuating plate 491 drives the sliding plate 44 to slide, so that the wedge 45 slides inward and separates from the locking block 46, contacting the locking and fixing of the insert 43. At this time, the upper baffle 32 of the air guide can be pulled out directly for quick disassembly.
