Then the upper end enclosure 1 is disassembled, the sticking and hanging condition of the attachments inside the shell 3 and on the outer wall of the heat exchange tube 4 is observed, then the shell is washed by high-pressure water, the attachments inside the shell 3 and on the outer wall of the heat exchange tube 4 are washed, and waste liquid is discharged to a waste water tank through a discharge port 202 at the bottom of the lower end enclosure 2. After the cleaning work is finished, the end socket is installed and restored, and then the end socket can be put into use again.

It should be noted that, under the guidance of the present invention, those skilled in the art can also make partial modifications to the above system. For example, a pump, a pressure sensor, a flow meter, a temperature sensor, and the like are arranged between different units or devices and equipment on a conveying pipeline inside the system, different valves are also arranged at the same time, such as a pressure relief valve, a pressure regulating valve, a safety valve, and the like which are used for regulating and stabilizing the pressure of the whole system, and the opening degree of the valves can be regulated to regulate the material flow in the pipeline, and the like. For another example, a sealing gasket is arranged at the flange joint of the end socket and the shell.

Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention, and not for limiting the same; while the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those skilled in the art that; the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
