TECHNICAL FIELD

[0001] The present application relates to the technical field of condensate water recovery, and more particularly to a condensate water recovery system with automatic water pump exhaust function. BACKGROUND

[0002] In a typical open condensate water recovery system, a liquid level controller is responsible for regulating the operation of the motor, thereby driving the high-temperature water pump to pressurize and deliver the water in the condensate water tank to the condensate water recovery pipeline. However, control system failure can cause the high-temperature water pump to suck in air, so that the pressure in the pump cannot reach the required level for normal operation, ultimately affecting the normal discharge of condensate water.

[0003] In the prior art, when the high-temperature water pump sucks in air, the air in the pump must be manually removed by unscrewing the exhaust hole bolt of the high-temperature water pump, which is time-consuming and labor-intensive, significantly reducing work efficiency.

It should be noted that the relative arrangement of the components and steps set forth in the examples, as well as the numerical expressions and values, are not limitations on the scope of the present application unless otherwise specifically stated.

[0025] The present application provides a condensate water recovery system with water pump automatic exhaust function, an exhaust pipeline is arranged on a high-temperature water pump on a water outlet pipeline of a condensate water recovery tank, and a controller judges whether the high-temperature water pump sucks in gas through a flow signal of a flow monitor, and automatically controls the exhaust pipeline to exhaust gas when the high-temperature water pump sucks in gas, so as to timely exhaust gas in the high-temperature water pump, and improve work efficiency.

[0026] As Figure 1 shown, the condensate water recovery system with automatic exhaust function of water pump provided by the present application comprises a condensate water recovery tank 10 and a controller (not shown in the figure).

[0027] The water inlet 11 of the condensate water recovery tank 10 is connected with the condensate water pipeline upstream, so that the condensate water flows into the condensate water recovery tank 10. The water outlet 12 of the condensate water recovery tank 10 is connected with the water outlet pipeline 20, which is provided with a stop valve and a high-temperature water pump 33. A flow monitor 32 is arranged between the water outlet 12 and the high-temperature water pump 33.

[0028] ‌The high-temperature water pump 33 is a kind of high-performance pump commonly seen in the market. By the magnetic field conduction between the outer magnet, the isolation sleeve and the inner magnet, the dynamic seal is converted into the static seal, so as to ensure the stability in the high-temperature environment. The first output end of the high-temperature water pump 33 is communicated with the condensate water recovery pipeline, and the second output end of the high-temperature water pump 33 is connected with the exhaust pipeline 40, which is provided with an electromagnetic valve 41 for exhaust.

[0029] The flow monitor 32 and the electromagnetic valve 41 are respectively connected with the controller signal. The controller is used to receive the water flow signal collected by the flow monitor 32, and then control the opening and closing of the electromagnetic valve 41 according to the water flow signal.

[0030] Preferably, as Figure 1 shown, the exhaust pipeline 40 is further provided with a first regulating valve 42 for manually adjusting the water pressure of the exhaust pipeline 40.

[0031] As an embodiment, the end of the exhaust pipeline 40 is connected with the waste water main pipe 70, and the end of the waste water main pipe 70 is provided with a floor drain 60, so that the condensate water in the exhaust pipeline 40 flows into the floor drain 60 through the waste water main pipe 70.

[0032] As an embodiment, the flow monitor 32 is an ultrasonic flow monitor.

[0033] As an embodiment, as Figure 1 shown, the flow monitor 32 and the water outlet 12 are further provided with a second regulating valve 31, and the water outlet 12 and the second regulating valve 31 are further provided with a drainage branch 80, so that the second regulating valve 31 and the pipeline downstream thereof on the water outlet pipeline 20 form a recovery branch 30, and the second regulating valve 31 is used to adjust the water pressure of the recovery branch.

[0034] As Figure 1 shown, the drainage branch 80 is provided with a stop valve and an electric valve 82 to automatically adjust the water pressure of the drainage branch 80. The end of the drainage branch 80 is connected with the waste water main pipe 70, and the condensate water in the condensate water recovery tank 10 directly flows into the floor drain 60 through the drainage branch 80 and the waste water main pipe 70.

[0035] Preferably, a third regulating valve 81 is arranged in parallel with the electric valve 82 on the drainage branch 80, for manually regulating the water pressure of the drainage branch 80.

[0036] As shown in Figure 1 The upper portion of the condensate recovery tank 10 is provided with an overflow port 13, which is connected with an overflow pipeline 50 for discharging overflow water in the condensate recovery tank 10.

[0037] As an embodiment, the end of the overflow pipeline 50 is provided with a floor drain 60.

[0038] In the present application, the flow monitor 32 monitors the water flow in the recovery branch in real time and sends it to the controller. When the controller determines that the water flow value exceeds the preset threshold range, the controller sends a control signal to the electromagnetic valve 41 to drive the electromagnetic valve 41 to open, thereby opening the exhaust pipeline 40, so that the gas in the high-temperature water pump 33 is discharged through the exhaust pipeline 40 under the driving of the condensate water. As the gas in the high-temperature water pump 33 is gradually discharged, the water flow value monitored by the flow monitor 32 gradually falls, and when the water flow value falls within the preset threshold range, the control unit controls the electromagnetic valve 41 to automatically close, thereby completing the whole process of automatic detection and exhaust of the water pump.

[0039] The present application can effectively solve the problem that the condensate water cannot be normally discharged due to the gas sucked by the high-temperature water pump. By real-time detection of the reliability of the condensate water discharge system and automatic identification and removal of hidden troubles, the need for manual intervention is significantly reduced, and the work efficiency is improved.

[0040] Although some specific embodiments of the present application have been described in detail through examples, those skilled in the art should understand that the above examples are only for illustration, but not for limiting the scope of the present application. Those skilled in the art should understand that the above embodiments can be modified without departing from the scope and spirit of the present application.
