[0002] The tube heat exchanger is the most widely used heat exchanger in chemical and alcohol production, and is also widely used in petroleum, pharmaceutical, food and other industrial fields. The working principle of the tube heat exchanger is that the hot fluid is transmitted into the heat pipe from the inlet, exchanges heat with the cold fluid, and then is discharged through the outlet after the temperature drops. At the same time, the cold fluid is transmitted into the last heat exchanger through the inlet, exchanges heat by cross-flow, is deflected by the flow partition plate, and then sequentially passes through the subsequent heat exchangers, and finally the cold fluid with a higher temperature enters the heat requiring device.

[0003] However, when the fluid passes through the inside of the heat exchanger, the temperature change will cause the sediment to adhere to the inner wall of the heat exchanger, which will cause the heat exchange efficiency of the heat exchanger to decrease and be blocked after a long time.
