Description
Technical Field
The utility model belongs to the technical field of steam turbine condenser water jet bleeds, especially, relate to a penetrate water tank overflow water circulating system.
Background
The condenser of the turbo generator set runs in a vacuum state, air leaking from a vacuum system is not tight, and condensation heat exchange in the condenser can be seriously influenced. In order to maintain reasonable vacuum inside the condenser, non-condensed gas in the condenser needs to be continuously pumped out. The gas pumped out from the condenser is mixed with the working water and then is injected into the water injection tank to release heat, and the water temperature of the water injection tank is continuously increased due to the heat generated by the operation of the water injection system. The performance of the water jet air extractor is greatly influenced by the temperature of working water, and the main reason is that after the temperature of the working water rises to a certain degree, the working water is vaporized at the throat part of a high-vacuum air extractor spray pipe, the volume is expanded, and the suction capacity of the air extractor is reduced. Practice shows that when the temperature of the water injection tank is higher than 26 ℃, the working efficiency of the water injection air extractor can be obviously reduced.
Therefore, in order to improve the efficiency of the water jet air ejector and ensure the vacuum of the condenser, the heat is taken away by the continuous water supplement and overflow mode of the water jet tank in the actual production process, and the water temperature of the water jet tank is controlled. The method can cause waste of water resources, is not environment-friendly and has low system operation efficiency.
