[0024] Specifically, a water pump is connected to one end of the feed pipe 7 and the water inlet pipe 3, and the cooling water is transported to the inside of the U-shaped water pipe 5 through the water inlet pipe 3. At the same time, the process fluid flows into the inside of the exchange tube 11 through the feed pipe 7. The exchange tube 11 is wrapped around the outer wall of the U-shaped water pipe 5 to achieve evaporative cooling of the process fluid. At the same time, when the cooling water flows in the U-shaped water pipe 5, the turbine 2 can be driven to rotate by the flow of cooling water, and then the rotating shaft 12 is driven to scrape the scale on the inner wall of the U-shaped water pipe 5 to avoid poor cooling efficiency due to the accumulation of scale. At the same time, the sleeve 6 can be removed by opening the card plate 14, and the turbine 2 or the rotating shaft 12 inside the U-shaped water pipe 5 can be damaged, repaired or replaced. At the same time, after the process fluid is cooled, it flows into the inside of the receiving barrel 9 through the discharge pipe 8 to collect the treated receiving barrel 9.

[0029] Working principle: cooling water is transported to the inside of the U-shaped water pipe 5 through the water inlet pipe 3, and the process fluid flows into the inside of the exchange tube 11 through the feed pipe 7. The exchange tube 11 is wrapped around the outer wall of the U-shaped water pipe 5 to realize evaporative cooling of the process fluid. At the same time, when the cooling water flows into the inside of the U-shaped water pipe 5 through the water inlet pipe 3, the turbine 2 is driven to rotate by the flow of cooling water, and the rotating shaft 12 and the scraper 13 are driven to rotate around the left side of the fixed frame 17, so that the scraper 13 is abutted against the inner wall of the U-shaped water pipe 5 to scrape off the scale on the inner wall of the U-shaped water pipe 5, so as to avoid poor cooling efficiency caused by the accumulation of scale. At the same time, the card plate 14 can be opened to disengage the card plate 14 and the lock shaft 15, so as to facilitate the removal of the sleeve 6 from the left end of the U-shaped water pipe 5, and facilitate the staff to take out the fixed frame 17 and the rotating shaft 12 for easy maintenance and replacement of the damaged ones. At the same time, when the process fluid is cooled, it flows into the inside of the receiving barrel 9 through the discharge pipe 8 to realize the collection of the treated receiving barrel 9.
