The air duct barrel 1 guides the air inlet and outlet, and the diversion reduces the impact and friction noise on the inner wall of the air duct circulation. The air duct assembly circulation noise is small, which makes it easy to disassemble and assemble the air duct filter element 5 inside the air duct barrel 1 for cleaning or maintenance and replacement.

[0023] Specifically, the connecting mechanism includes flange No. 1 7 and flange No. 2 8. Flange No. 1 is integrally provided at one end of the air inlet 2, and flange No. 2 is integrally provided at the end of the air duct barrel 1 away from the air outlet 3. Flange No. 1 7 and flange No. 2 8 are fixed by assembly bolts, and a sealing ring is provided between flange No. 1 7 and flange No. 2 8 through a sealing groove. A threaded seat 10 is provided on the side of flange No. 1 away from the air inlet 2, and the threaded seat 10 is connected to the air inlet 2. A threaded opening 9 is provided at the open end of the air duct filter element 5, and the threaded opening 9 is threadedly connected to the threaded seat 10. The air duct filter element 5 and flange No. 1 are convenient to disassemble and assemble, and the air inlet 2 and the air duct barrel 1 are convenient to disassemble and assemble, thereby making it convenient to clean and replace the air duct filter element 5.

[0024] Furthermore, one end of the air duct cylinder 1 close to the air outlet 3 is arranged in a conical cylinder structure, the other end of the air duct cylinder 1 is arranged in a cylindrical structure, the inner wall of the air duct cylinder 1 is provided with a noise reduction lining 11, and the end of the air inlet 2 close to the No. 1 flange 7 is arranged in a conical cylinder structure, and the air intake and outlet of the air duct cylinder 1 are smooth.

[0025] Furthermore, a number of filter element skeletons 6 are provided, and the filter element skeletons 6 are distributed at equal intervals.

The air is dispersed from the inside to the outside during circulation and passes through the coarse filter screen 52, the activated carbon filter screen 53 and the fine filter screen 51 of the air duct filter element 5 for multi-stage filtration treatment. The air outlet guide ring 4 inside the air duct cylinder 1 guides and concentrates the air outlet on the edge inside the air outlet end of the air duct cylinder 1. The filtered guide air in the air duct cylinder 1 is guided and concentrated out of the air duct cylinder 1 through the air outlet guide ring 4 from the air outlet 3 to the ventilation duct of the refrigeration equipment. The air duct filter element 5 realizes the function of air circulation filtering of the refrigeration equipment. The outlet guide ring 4 and the air inlet guide ring 41 guide the air inlet and outlet of the air duct cylinder 1, and the diversion reduces the air flow in the air duct.
