The collection box 8 is connected to the heat exchange tube 3 end to end by a bolt assembly, and the collection box 8 is in communication with the heat exchange tube 3. A support tube 1 is fixedly installed at the end of the heat exchange tube 3 by a bolt assembly. A fixing plate 12 is fixedly installed at the end of the heat exchange tube 3 by a bolt assembly. The end of the fixing plate 12 is fixedly connected to the end of the heat exchange rod 14 by a bolt assembly.

[0023] The inlet 2 and outlet 5 are fixedly installed on the outer side wall of the heat exchange tube 3 by bolt assemblies, and the cooling interface 4 and cooling outlet 6 are fixedly installed on the outer side wall of the heat exchange tube 3 by bolt assemblies, which facilitates the heat exchange treatment of high-salt wastewater by operators.

[0024] Multiple heat exchange rods 14 are linearly arranged inside the heat exchange tube 3. The fixing plate 12 is fixedly installed at the end of the heat exchange tube 3 by bolt assembly. The end of the fixing plate 12 is fixedly connected to the end of the multiple heat exchange rods 14 by bolt assembly, thus providing support for the heat exchange rods 14.

[0025] The heat exchange tube 3 is also provided with a scraper 13. The scraper 13 has a plurality of first movable holes adapted to the heat exchange rod 14. The scraper 13 is set on the outer side wall of the heat exchange rod 14 through the plurality of first movable holes. The electric push rod 9 is fixedly set on the inner side wall of the support tube 1 by bolt assembly. The output end of the electric push rod 9 is provided with a support assembly, and the support assembly is connected to the scraper 13. The support assembly includes a support plate 10 and a plurality of first connecting rods 11. The support plate 10 is fixedly set on the output end of the electric push rod 9 by bolt assembly. This arrangement enables the electric push rod 9 to drive the support plate 10 to move, providing driving force for the scraper 13.

[0026] Multiple first connecting rods 11 are circumferentially fixed at the end of the support plate 10 by bolt assemblies. The other end of the first connecting rod 11 is fixedly connected to the end of the scraper 13 by bolt assemblies. Multiple second movable holes adapted to the first connecting rods 11 are opened on the support plate 10. The first connecting rods 11 are slidably inserted into the support plate 10. This arrangement causes the electric push rod 9 to drive the multiple first connecting rods 11 to move. The multiple first connecting rods 11 drive the scraper 13 to scrape off the dirt on the outer wall of the heat exchange rod 14. At the same time, the scraper 13 scrapes off the dirt on the inner wall of the heat exchange tube 3. Since high-salt wastewater contains a variety of substances, dirt is easily generated inside the heat exchange tube 3. Excessive dirt will reduce the treatment efficiency of high-salt wastewater.

[0027] The heat exchange tube 3 has a movable cavity, a spring 21 is installed in the movable cavity, a sliding groove 20 is installed in the movable cavity, and a T-shaped slider 23 is installed in the sliding groove 20.

The connecting plate 16 has symmetrical third movable holes on both sides, and the connecting plate 16 slides on the support rod 17 through the third movable holes. The servo motor 7 drives the lead screw 18 to rotate, and the lead screw 18 drives the connecting plate 16 to move. The connecting plate 16 drives the arc plate 19 to clean the dirt on the baffle 15, thereby improving the cleaning efficiency of the dirt.

[0032] The aforementioned bolt assembly and rotating assembly are both existing technologies. The bolt assembly includes a bolt and a threaded hole for threading two components together. The rotating assembly includes a rotating groove, an annular block, and an annular groove. The annular groove is formed on the inner wall of the rotating groove, and the annular block rotates within the annular groove.

[0033] The functional principle of this utility model can be explained through the following operation methods:

[0034] High-salt wastewater is injected into heat exchange tube 3 through inlet 2 for heat exchange treatment. Substances in the high-salt wastewater adhere to the outer wall of heat exchange rod 14.
