Description
Technical Field
The utility model relates to a steam turbine condenser water jet air exhaust technical field specifically is a water conservation and energy saving type water jet air ejector 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 has shown that the suction chamber pressure of the air extractor increases by 1.96kPa for every 5 ℃ rise in the operating water temperature above 30 ℃.
In order to improve the efficiency of the water jet air ejector and ensure the vacuum of the steam engine, the heat is taken away by frequently carrying out continuous water supplement and overflow on the water jet tank in the actual production process, and the water temperature of the water jet tank is controlled. The method has high water replenishing loss and heat loss, is not environment-friendly, and has low system operation efficiency.
Disclosure of Invention
The utility model aims at providing a water conservation and energy saving type water jet air ejector system, which aims to solve the problems that the mode of controlling the temperature of a water jet tank by water replenishing and overflowing modes has higher water replenishing loss and thermal loss, is not environment-friendly and has low system operation efficiency.
The utility model has the following concrete scheme: the utility model provides a water conservation and energy saving type water jet air ejector system, includes condenser, water jet air ejector, water jet pump, jet water tank, and the condenser below is provided with the hot well that is used for adorning the condensate water, the water jet pump is connected the end of intaking of jet water tank and water jet air ejector, and the inlet end of water jet air ejector passes through the pipeline and is connected with the condenser, and the end of jetting of water jet air ejector is towards the jet water tank, the hot well is equipped with an outlet pipe, be equipped with the coil pipe in the jet water tank, the outlet pipe passes through tee junction coil pipe one end, and the jet water tank is worn to the coil pipe other end, tee bend one end is equipped with the moisturizing.
The valve is arranged on the water replenishing pipe and the water outlet pipe.
