[0023] The steam is input from the first steam condensate main pipe 14 to the air storage box 12, so that the temperature of the air storage box 12 increases, and a temperature difference occurs between the temperature inside the air storage box 12 and the temperature outside the air storage box 12. After the temperature of the air storage box 12 increases, the heating end of the semiconductor refrigeration plate 123 is heated, so that there is a temperature difference between the two ends of the semiconductor refrigeration plate 123, thereby realizing temperature difference power generation, realizing steam heat energy recovery and reuse, and cooling the steam for the first time. Then the steam enters the elbow 15 through the air storage box 12, and the water in the heat exchange box 11 absorbs the steam heat, and then condenses the steam. The liquid water produced by the condensation passes through the three-way pipe 16 and is separated into gas and liquid through the steam drain valve in the three-way pipe 16, so that the condensed water enters the water storage tank 13 from one output end, and the remaining part of the gas passes through the second steam condensate main pipe 141 at the other output end, thereby realizing the recovery and reuse of the steam condensate.

[0024] A first connecting pipe 17 is sealed and fixedly connected to the side wall of the water storage tank 13 close to the heat exchange box 11, and a water pump 171 is sealed and fixedly connected to the end of the first connecting pipe 17 away from the water storage tank 13. A second connecting pipe 172 is fixedly connected to the output end of the water pump 171, and an end of the second connecting pipe 172 away from the water pump 171 is sealed and fixedly connected to the heat exchange box 11, so as to utilize the water pump 171 to input the water with lower temperature in the water storage tank 13 into the heat exchange box 11 through the first connecting pipe 17 and the second connecting pipe 172, thereby cooling the heat exchange box 11, thereby reducing the frequency of replacing the water in the heat exchange box 11.

[0027] A fan 19 is fixedly connected to the side wall of the installation shell 2 close to the water storage tank 13, which is used to use the fan 19 to dissipate heat from the inside of the installation shell 2 and further accelerate the cooling of the water in the water storage tank 13.

[0029] Working principle: First, steam is input from the first steam condensate main pipe 14 into the air storage box 12. The temperature of the air storage box 12 rises, and a temperature difference occurs between the temperature inside the air storage box 12 and the temperature outside the air storage box 12. After the temperature of the air storage box 12 rises, the heating end of the semiconductor refrigeration plate 123 is heated. The temperature difference between the two ends of the semiconductor refrigeration plate 123 realizes temperature difference power generation, and the steam heat energy is recovered and reused. The steam is cooled for the first time, and then the steam passes through the air storage box 12 into the elbow 15, and the water in the heat exchange box 11 absorbs the heat of the steam, and then the steam is condensed. The liquid water produced by the condensation passes through the three-way pipe 16, and is separated into gas and liquid through the steam trap in the three-way pipe 16. The condensed water enters the water storage tank 13 from one output end, and the remaining part of the gas passes through the second steam condensate main pipe 141 at the other output end, thereby realizing the recovery and reuse of the steam condensate. Secondly, the water in the water storage tank 13 is cooled by the fan 19 and the heat sink 132. The temperature signals of the water in the heat exchange box 11 and the water storage tank 13 are transmitted to the controller 3 by the first temperature sensor 31 and the second temperature sensor 32. Then the controller 3 controls the water pump 171 to input the water with lower temperature in the water storage tank 13 into the heat exchange box 11 through the first connecting pipe 17 and the second connecting pipe 172, thereby cooling the heat exchange box 11, which can reduce the frequency of replacing the water in the heat exchange box 11.
