The return pipe 441 is connected to the rear side of the transmission runner 42. The rear side of the return pipe 441 is rotatably connected to the rear side inside the gas collecting cylinder 411. The circulation rod 442 is fixedly connected to the inside of the return pipe 441. The circulation spiral plate 443 is fixedly connected to the surface of the circulation rod 442. By providing the circulation pipe 44, the return pipe 441 can convey the coolant to the condensing pipe 45, and provide an auxiliary pushing force for the coolant along the rotation of the transmission runner 42 through the circulation rod 442 and the circulation spiral plate 443 to convey the coolant to the condensing pipe 45, so as to improve the efficiency of circulating and conveying the coolant.

[0058] Among them, the top of the rear side of the return pipe 441 is communicated with the rear side of the condensing pipe 45, and the surface of the return pipe 441 is in contact with the inner side of the condensing pipe 45. By setting the surface of the return pipe 441 to be in contact with the inner side of the condensing pipe 45, the return pipe 441 can support the condensing pipe 45, increasing the stability of the condensing pipe 45 during rotation. By communicating the top of the rear side of the return pipe 441 with the rear side of the condensing pipe 45, the coolant can flow gradually forward along the condensing pipe 45 from the rear side of the return pipe 441, and then flow back to the rear side of the condensing pipe 45 from the front side of the return pipe 441, forming a one-way circulating flow, improving the stability of the coolant during circulating flow.

[0059] Among them, the condensing pipe 45 includes a spiral condensate pipe 451, a closed-loop pipe 452 and a spiral scraper 453. The spiral condensate pipe 451 is communicated with the front side of the return pipe 441, the closed-loop pipe 452 is communicated with the front side of the spiral condensate pipe 451, and the front side of the closed-loop pipe 452 is communicated with the rear side of the transmission runner 42. By setting the condensing pipe 45, the spiral condensate pipe 451 can increase the contact range with the waste gas through its own spiral shape, thereby further improving the efficiency of condensing the waste gas. The closed-loop pipe 452 can convey the coolant conveyed by the spiral condensate pipe 451 to the transmission runner 42, and can limit the spiral condensate pipe 451 and the transmission runner 42, increasing the stability of the spiral condensate pipe 451 during rotation with the transmission runner 42.

[0060] Among them, the spiral scraper 453 is fixedly connected to the surface of the spiral condensate pipe 451, and the surface of the spiral scraper 453 is in contact with the inner side of the air collecting cylinder 411. By setting the spiral scraper 453, it can rotate together with the spiral condensate pipe 451 inside the air collecting cylinder 411 during rotation, and push the liquid remaining in the air collecting cylinder 411 to the liquid extraction pump 412 gradually during rotation, improving the efficiency of the liquid extraction pump 412 for waste liquid recovery.

[0061] The working principle of this embodiment: First, the waste gas will rise to the air collecting cylinder 411 along with the heat. Then, the transmission belt 3 will drive the transmission runner 42 to rotate synchronously with the rotation of the drying mechanism 2. The transmission runner 42 will drive the circulation pipe 44 and the condensing pipe 45 to rotate. The circulation rod 442 will drive the circulation spiral plate 443 to convey the coolant in the return pipe 441 into the spiral condensate pipe 451 during rotation and form a one-way circulating flow. When the waste gas contacts the spiral condensate pipe 451, it will condense into waste liquid with the low temperature of the coolant and drip into the recovery cylinder 41. After that, the waste liquid will move towards the liquid extraction pump 412 with the movement of the spiral scraper 453. The liquid extraction pump 412 will convey the waste liquid to the storage tank 413 for storage. The cooling pipe 431 will disperse the heat of the flowing coolant to the surroundings through the heat dissipation fins 433, thereby cooling the coolant until the impurities in the waste gas are completely recovered.
