Water level control system for deoxygenated water tank

Abstract

The invention discloses a water level control system for a deoxygenated water tank. The system comprises a water level detection unit for detecting a water level height in the deoxygenated water tank in real time, a water supply control valve and a water pump which are arranged on a water supply pipeline, a controller and a parameter input device, and also comprises a water supplementing device, wherein the water supplementing device comprises a water supplementing tank which automatically supplements water into the deoxygenated water tank under the action of gravity, a water supplementing pipeline connected between the water supplementing tank and the deoxygenated water tank, a water supplementing control valve arranged on the water supplementing pipeline, a water injection pipe for injecting water into the water supplementing tank under the driving action of the water pump, and a water injection control valve arranged on the water injection pipe; and the water supplementing tank is obliquely arranged above the deoxygenated water tank. The water level control system has the advantages of reasonable design, high intelligent degree and good using effect, is convenient to mount and easy to operate, and can overcome the defects that the controller frequently controls the water pump to start or stop, the power consumption is high, normal performance characteristics of the water pump and a deoxygenator are influenced, and the like in the existing water level control system for the deoxygenated water tank due to water level fluctuation in the deoxygenated water tank.

Description

technical field [0001] The invention relates to a water level control system, in particular to a water level control system for a deoxygenated water tank. Background technique [0002] The deaerator is a thermal deaerator that works according to the law of gas dissolution (namely Henry's law). The law of gas dissolution indicates that the solubility of any gas in water is related to the partial pressure of the gas on the gas-water interface and the water temperature. High, the higher the partial pressure of water vapor, the lower the partial pressure of other gases; when the water temperature rises to boiling, the partial pressure of other gases is zero, and the other gases dissolved in water are also equal to zero. Thermal deaerators are divided into two specific types: atmospheric deaerators and pressure deaerators. Thermal deaerators heat water to the boiling point, and after the water is heated to the boiling point, the solubility of oxygen in the water gradually decreas...

Problems solved by technology

However, since the liquid level in the deaeration water tank tends to fluctuate during actual use, the water level parameters in the deaeration water tank detected by the water level detection unit also fluctuate up and down, which causes the controller to frequently control the start and stop of the water pump, which not only consumes It consumes electricity and has a great impact on the performance of the water pump, so that the service life of the water pump is relatively shortened, and it will also have a great impact on the normal operation of the deaerator
