[0002] Many production enterprises need to use water cooling process in production, such as chemical enterprises, mining enterprises and metal smelting enterprises.

[0003] In the water cooling process, most of the energy existing in the form of heat is lost, which not only causes serious energy waste, but also has certain impact on the environment.

[0004] In the water cooling process of high-temperature materials, steam is often generated. However, the generated steam has low quality, slow airflow and low temperature, which is difficult to drive power generation equipment, so it cannot be used for power generation. If the water cooling pool is to generate steam of sufficient quality, the cooling pool of the water cooling process needs to be sealed and pressurized.

[0005] However, if the cooling pool of the water cooling process is pressurized, it is difficult to ensure the internal pressure of the cooling pool when the materials are put into the cooling pool. SUMMARY
