[0019] Please refer to Figure 1 and Figure 2, an embodiment of the present utility model provides a multi-source surplus water recovery and utilization system, including a condensate recovery unit and a condensate recovery unit.

The filtering component 1 is connected to the cooling tower circulation component. In this embodiment, by the cooperation of the condensate recovery unit and the condensate recovery unit, the condensate and condensate generated in different scenarios can be centrally collected, with high utilization rate of surplus water resources, environmental protection, energy saving, low power consumption, and greatly reducing production costs. Specifically, the sources of condensate are such as dehumidifying air conditioners, fan coil air conditioning units, etc., and the sources of condensate are such as high-temperature condensate generated by dehumidifying air conditioners, high-temperature condensate generated by steam heat exchangers, high-temperature condensate generated by steam separators, etc. Among them, the high-temperature condensate generated by the dehumidifying air conditioner is processed by the pneumatic condensate recovery device 3 and then input into the heat preservation tank 4. The heat preservation tank 4 also has other condensate input ends 17, respectively for inputting high-temperature condensate generated by steam heat exchangers and high-temperature condensate generated by steam separators. This heat preservation tank 4 can be a closed softening heat preservation condensate water tank. After the condensate enters the recovery tank group, it is pumped by the recovery tank group to the filtering component 1 for filtering. The treated condensate is respectively input into the make-up water tank 2 and the cooling tower circulation component. The make-up water tank 2 can supply water for other links. The cooling tower circulation component adjusts the temperature of the condensate and then sends it to the refrigerant air conditioner cooling water circulation unit 20 for use, making reasonable use of the condensate. Preferably, the make-up water tank 2 is related to a water supply unit. The water supply unit can be composed of components such as a recovery tank group, a water pump, a supporting control cabinet, the make-up water tank 2, electronic liquid level gauges in each water tank, solenoid valves on the water supply side of the make-up water tank 2 and the water supply side of the high-temperature cooling tower 12, and weak current control lines, etc., and can automatically start and stop according to the liquid level conditions of each water tank. The specific start and stop rules are as follows: when the liquid level of the make-up water tank 2 is lower than the set value, a signal is transmitted to the control cabinet to start the water pump, and when the water level of the air-conditioning condensate water tank 16 is lower than the warning value, the water pump stops working, and when the make-up water tank 2 is higher than the warning value, the solenoid valve automatically closes. When the high-temperature cooling tower 12 is running, when the water level of the air-conditioning condensate water tank 16 is higher than the set value, a signal is transmitted to the control cabinet to start the water pump, and when it is lower than the set value, although a signal is received, the water pump is not started, and when the water level of the air-conditioning condensate water tank 16 is lower than the warning value, the water pump stops working. Preferably, a steam trap and a condensate pipeline are provided at the bottom of the steam separator, and are connected to the heat preservation tank 4 through the steam trap and the condensate pipeline. Preferably, the system also includes a constant pressure water supply unit, which is connected to the air-conditioning hot water heat exchange circulation pipeline of the comprehensive station building and automatically supplies water according to the network pressure situation.

The steam-water heat exchanger 6 is a prior art and will not be elaborated here. There can be two main hot water supply pipes with temperatures of about 50°C and 55°C respectively. Preferably, the condensate outlet 8 is connected to the insulation box 4 through a pneumatic pump 9.
