[0024] In this embodiment, the high-temperature steam coming out of the heat exchange unit 11 and the cold water flowing out of the water storage tank 1 can be uniformly gathered into the heat exchange tank 4 under the mutual cooperation of the steam heat pipe 6 and the cold water pipe 2. The high-temperature steam can exchange heat with the cold water, realizing the waste heat recovery of the steam, which is beneficial to improving the profit effect of equipment production.

[0026] In this embodiment, the heat exchange component 8 in the heat exchange tank 4 is mainly composed of an outer coil 9 and an inner vertical pipe 10. The outer coil 9 and the inner vertical pipe 10 increase the heat exchange area, which is beneficial to improving the actual conversion rate of thermal energy and reducing the waste of thermal energy.

[0033] Working principle: The high-temperature steam coming out of the heat exchange unit 11 will be transported to the heat exchange tank 4 through the steam heat pipe 6. At the same time, the cold water flowing out of the water storage tank 1 will be transported to the heat exchange tank 4 through the cold water pipe 2. The high-temperature steam will transfer heat energy to the cold water in the heat exchange component 8, thereby realizing heat exchange between the high-temperature steam and the cold water.
