DETAILED DESCRIPTION
[0013] See also Figure 2 In the original water jet tank overflow water drainage system, the overflow is discharged to the rainwater drainage pipe naturally. In order to reduce the waste of water resources and reduce the operating cost, this embodiment improves this and recycles the overflow water. Figure 1 As shown, it includes a first pipe 2 connected to the water shooting box 1, and the first pipe 2 is connected to the external rain drainage pipe through the second valve 9 and the fourth pipe 10, so as to naturally discharge a part of the overflow water of the water shooting box. A recovery water tank 3 is connected to the end of the first pipe 2 away from the water shooting box 1, and at the same time, a first valve 8 for opening and closing the pipe to the overflow water of the recovery water tank 3 is arranged on the first pipe 2. The first water pump 5 and the second water pump 13 are connected in the recovery water tank 3 through the second pipe 4, and the water outlet ends of the first water pump 5 and the second water pump 13 are respectively connected to the third pipe 6, and the two third pipes 6 converge into the cooling tower water tank, and the two third pipes 6 are provided with a check valve 12 and a stop valve 11.
[0014] Specifically, a liquid level controller 14 is also installed in the recovery pool 3 in this embodiment. The liquid level controller 14 is connected to the water pump control box 7. The liquid level controller 14 is used to sense the water level in the recovery pool 3, thereby controlling one or both of the first water pump 5 and the second water pump 13 to start. When the liquid level is low, one water pump is turned on, and when the liquid level is high, both water pumps are turned on.
[0015] It should be noted that the first water pump 5 and the second water pump 13 described in this embodiment are specifically suction-type water pumps or self-priming water pumps. The water pumps themselves are not immersed in water, but are connected to a water source through a pipe to absorb water. At the same time, the specifications of the water pumps can be selected according to the hourly flow rate of overflow water.
[0016] Based on the above, this embodiment adds two valves to the overflow water pipe of the existing water injection tank according to the operating conditions of the water injection tank of the saturated steam power generation system. One valve can realize the function of natural discharge, and the other valve is connected to the recovery pool 3. A pipe is led from the other valve to the pool for storage, and then a water pump is used to pump the water in the pool into the cooling tower pool of the saturated steam power generation for recycling, and the number of water pumps opened can be controlled according to the flow rate of the overflow water.
[0017] In addition to the above embodiments, the present invention may also have other implementation modes; any technical solutions formed by equivalent replacement or equivalent transformation shall fall within the protection scope required by the present invention.
