It will be appreciated that during operation of the circulating water condensing system, water or water vapor may be lost due to leakage or the like. In order to replenish water to the circulating water condensation system, as shown in fig. 1, in this embodiment, the circulating water condensation system further includes a communicating pipe 8, a water replenishing tank 9, and a second controller 10. Wherein the communication pipe 8 has a first end and a second end connected to the bottom of the water collection tank 6.

Thus, when the amount of water in the water collecting tank 6 is too small, based on the principle of communicating vessels, the liquid level in the water replenishing tank 9 should be low, and at this time, the second controller 10 controls the second valve 93 to open, so that water flows into the water replenishing tank 9 through the water replenishing hole 92, and water replenishing to the water replenishing tank 9 and the water collecting tank 6 is realized.
Further, in order to avoid excessive water (e.g. exceeding the maximum water level) in the water replenishing tank 9 and the water collecting tank 6, in this embodiment, the second controller 10 is further configured to control the second valve 93 to close when the liquid level detected by the second liquid level sensor 91 is not lower than a preset second liquid level.
Understandably, the steam in the heating pipe 1 may be a small amount of steam and enter the water collecting tank 6 through the condensate pipe 2, therefore, if the second liquid level sensor 91 is installed in the water collecting tank 6, the second liquid level sensor 91 is easy to break down due to high temperature on the one hand, and on the other hand, the second liquid level sensor 91 is not favorable for overhauling the second liquid level sensor 91 due to the fact that the staff needs to wait for the water collecting tank 6 to be cooled and then enter the water collecting tank 6. Therefore, in the embodiment, the second liquid level sensor 91 is installed on the water replenishing tank 9, so that the second liquid level sensor 91 can be prevented from being subjected to high temperature, and the second liquid level sensor 91 is favorable for maintenance.
