When the motor 14 is started, the threaded rod 16 is driven to rotate, and the support plate 17 is driven to move along the threaded rod 16, so that the brush 19 can move along the heat exchange tube 12.

[0024] In the embodiments of the present invention, please refer to Figure 3 A plurality of support columns 18 are fixedly connected to the bottom of the condenser body 1, and a support plate 17 is slidably connected to the support columns 18, so that the support plate 17 can move stably through the support columns 18.

[0025] In the embodiments of the present invention, please refer to Figure 1 and Figure 2 The right side of the bottom of the circulating water outlet tank 2 is fixedly connected with an outlet pipe 8, which is used for recycling cooling water. The middle of the bottom of the circulating water outlet tank 2 is fixedly connected with a drain pipe 7, which is convenient for discharging the pickling liquid inside the circulating water inlet tank 3.

[0026] In the embodiments of the present invention, please refer to Figure 1 and Figure 2 A drain pipe 6 is fixedly connected to the right side of the bottom of the circulating water inlet tank 3. The drain pipe 6 discharges the pickling liquid inside the circulating water outlet tank 2. A condensate outlet pipe 10 is fixedly connected to the middle of the bottom of the condenser body 1.

[0029] The working principle of the heat exchange tube cleaning device for the compressor surface cooler provided by the present invention is as follows: when working, first close the sewage pipe 6, the drain pipe 7 and the pickling liquid inlet pipe 13, and the cooling water enters the circulating water inlet tank 3 through the water inlet pipe 5, and sends the cooling water to the heat exchange tube 12. The cooling water will not flow back through the one-way valve 9, thereby increasing the flow rate and improving the heat exchange efficiency of the condenser. At this time, the steam from the turbine enters the condenser body 1 through the steam turbine steam outlet pipe 4, and the steam is heat exchanged through the heat exchange tube 12. The condensed water generated is discharged through the condensate outlet pipe 10 for subsequent recycling. The cooling water after heat exchange enters the circulating water outlet tank 2 and is discharged through the outlet pipe 8. When used for a long time, By starting the motor 14, the threaded rod 16 is driven to rotate, and the support plate 17 is driven to move along the threaded rod 16, so that the brush 19 moves along the heat exchange tube 12 to remove the scale on the surface of the heat exchange tube 12 and increase the heat exchange efficiency. Then the drain pipe 7 and the outlet pipe 8 are closed, and the pickling liquid is added from the pickling liquid inlet pipe 13 to fully react the scale inside the heat exchange tube 12 to prevent the scaling from affecting the subsequent heat exchange efficiency. After the pickling is completed, the drain pipe 7 and the sewage pipe 6 are opened to discharge the pickling liquid inside the circulating water outlet tank 2 and the circulating water inlet tank 3, and then the circulating water side is backwashed through the outlet pipe 8, and the heat exchange tube 12 is repeatedly rinsed with clean water to ensure that the pickling liquid is completely removed to avoid damage to the equipment by residues. Finally, the flushing liquid is discharged through the sewage pipe 6.
