Problems solved by technology

Since the water level of the deaeration water tank will fluctuate during the working process, when the detector detects the change of the water level, the frequency of change is very large, which requires the water supply motor to be turned on frequently, which increases the energy consumption

Embodiment Construction

[0008] Such as figure 1 As shown, a water level control system for a boiler deaeration water tank includes a softened water tank 1 and a boiler deaeration water tank 5 equipped with a water level sensor inside. A deaeration water pump 2 is connected, and a pressure sensor 4 is also connected to the connection between the pipeline 3 and the boiler deaeration water tank 5. The pressure sensor 4 is connected to the controller 7, and the controller 7 is also connected to the water level sensor joint on the boiler deaeration water tank 5. 6 is connected, and the controller 7 is also connected with the motor of the deaeration water pump 2. The motor of the deaeration water pump 2 is a variable frequency motor.

[0009] The softened water in the softened water tank 1 is input to the boiler deoxygenated water tank 5 through the deaeration water pump 2, and a pressure sensor 4 is arranged at the entrance of the boiler deaeration water tank 5, and the pressure sensor 4 monitors the pre...

Abstract

The invention discloses a water level control system of a boiler deoxygenation water tank, which comprises a softened water tank and a boiler deoxygenation water tank equipped with a water level sensor inside. The water pump, the connection between the pipeline and the deaeration water tank of the boiler is also connected with a pressure sensor, the pressure sensor is connected with the controller, the controller is also connected with the water level sensor joint on the deaeration water tank of the boiler, and the controller is also connected with the deaeration water pump connected to the motor. The system can adjust the water supply in time and accurately control the water level of the deaeration water tank of the boiler.

Description

technical field [0001] The invention belongs to the field of automatic control, and in particular relates to a water level control system of a boiler deaeration water tank. Background technique [0002] In the boiler feed water treatment process, oxygen removal is a very critical link. The deaerator is a thermal deaerator that works according to the law of gas dissolution. In the industrial production process, in the actual process, the use conditions of the thermal deaerator are very harsh, and the mixing temperature of the inlet water, the working temperature and the steam pressure are all important. There are relatively strict requirements, and the water level change in the deaeration water tank also greatly affects the stability of the deaeration water tank. Since the water level of the deoxygenated water tank fluctuates during the working process, when the detector detects the change of the water level, the frequency of the change is very large, which requires the wate...
