Detailed Description
The utility model is further described below with reference to the accompanying drawings.
As shown in fig. 1-3, a constant temperature control device for a condenser comprises a primary water circulation and a secondary water circulation, wherein the primary water circulation consists of a circulation system 1, a water supplementing system 2 and a condenser 3, and the secondary water circulation consists of the condenser 3, a recovery system 4 and the water supplementing system 2.
With continued reference to fig. 2, the circulation system 1 mainly includes a water inlet pipe 11 and a water outlet pipe 12, one end of the water inlet pipe 11 is connected to a solenoid in the condenser 3, the other end is connected to a circulating water pump 14, one end of the water outlet pipe 12 is connected to the solenoid in the condenser 3, and the other end is connected to the circulating water pump 14, and water circulation is achieved through the action of the circulating water pump 14.
The water inlet pipe 11 is provided with a temperature sensor 13, the water inlet pipe 22 of the water supplementing system 2 is connected with the water outlet pipe 12, the junction is provided with a temperature control valve, the temperature control valve comprises an electric regulating valve 21 and a PID temperature controller 24, the PID temperature controller 24 is connected with the residual temperature sensor 13 through signals, and water temperature signals detected by the temperature sensor 13 are received. When the water temperature in the circulating system 1 reaches a certain value, the PID temperature controller 24 drives the electric regulating valve 21 to open, so that cold water in the water supplementing system 2 enters the circulating system 1, and the water temperature in the circulating system 1 is reduced. Specifically, when the temperature of the circulating water entering the condenser 3 reaches 65 ℃, the water supplementing system 2 operates, and cooling water is added into the primary water circulation to cool.
With continued reference to fig. 3, when the condenser is operated, a large amount of heat is generated, so that the pressure in the circulation system rises, and when the pressure reaches a certain value, the pressure is released from the pressure release pipe 31, and a part of hot water is discharged from the stop expansion relief valve 32 of the pressure release pipe 31. Since the pressure release pipe 31 is connected to the recovery system 4, the discharged hot water may enter the recovery system 4.
Hot water enters the cooling tank 41 through the pressure relief pipe 31, the cooling tank 41 is cooled, a temperature sensor is also arranged in the cooling tank and used for monitoring the water temperature in the cooling tank, and when the water temperature reaches the room temperature, the cooled water can be conveyed into the cold water tank 23 through the water pump 42. The cold water tank 23 is provided with a water inlet pipe 22 connected to the circulation system 1. The cold water tank 23 is also connected with an external water source, and the external cold water and the cooled cooling water in the cooling tank 41 are used for water circulation.
The traditional cooling water circulation structure needs to ensure that the temperature of water entering the condenser is lower than 60 ℃, a large amount of cooling water needs to be continuously injected, and a large amount of energy and water resources need to be consumed in the water injection process. After the device is adopted, water in the secondary water circulation and external cold water are used as a cooling water source together, so that the actual cold water supplementing amount of the condenser is reduced, and the water source is saved. Moreover, only the temperature rise is detected in the circulating system 1, then the temperature control valve is opened to perform water injection, so that the energy consumption can be reduced, only little cooling water is needed, and the temperature balance can be achieved through the control of the temperature control valve.
