Abstract
The utility model discloses a water jet and air exhaust system of a steam turbine, which comprises a condenser, a circulating water tank, a water jet pump, a water jet type air exhauster and a water jet tank. Water inlet and outlet pipelines of the condenser are communicated to the circulating water tank circularly, a water inlet of the water jet pump is communicated with the water jet pump, a water outlet of the water jet pump and an air exhaust pipeline of the condenser are communicated to an inlet of the water jet type air exhauster, a water jet tank water refilling pipeline is mounted on one of water inlet pipelines of the condenser via a tee joint, and a water outlet pipe of the water jet type air exhauster is directly led into the circulating water tank. Compared with the prior art, the water jet and air exhaust system of a steam turbine has the advantages that gas in the condenser, which is not cooled sufficiently due to low temperature of water, can be cooled sufficiently, air exhaust effect is excellent, and vacuum degree in operation of units is increased. Simultaneously, since soft water is replaced by circulating water in use, cost for power generation is saved.
Description
Technical field
The utility model relates to a kind of steam turbine, especially a kind of jetting extract system of steam turbine.
Background technique
The jetting extract system of traditional steam turbine uses softened water, and the moisturizing specific consumption is bigger, and since water temperature than higher, running temperature is about 50 ℃～60 ℃ at ordinary times, influence the water-blaster effect of bleeding, the condenser vacuum degree is low when causing unit operation, and unit efficiency descends.This situation is especially outstanding in summer.Therefore, designing the steam turbine that a kind of jetting extract system uses circulating water, is the present technical issues that need to address.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of jetting extract system that uses circulating water.
The technical scheme in the invention for solving the technical problem is:
A kind of jetting extract system of steam turbine, comprise condenser, circulating water pool, water-jet pump, jetting formula air ejector and jetting case, the inlet and outlet pipe lines of condenser is communicated with the circulating water pool circulation, the water intake of water-jet pump is communicated with the jetting case, the water outlet of water-jet pump and the pump-line of condenser are communicated with the import of jetting formula air ejector, wherein by threeway a jetting case moisturizing pipeline is installed on an intake pipe at condenser, with original jetting case moisturizing changing condenser circulating water, the outlet pipe of jetting formula air ejector directly advances circulating water pool, jetting case water can access sufficient cooling like this, water temperature remains on reduced levels always, and is the highest 35 ℃.The outlet pipe of jetting formula air ejector is provided with jetting formula air ejector outlet pipe valve.Jetting case moisturizing pipeline is provided with jetting case water-adding pipe valve.
Compared with prior art, the utility model jetting extract system uses circulating water, because water temperature is low, the gas that does not fully cool off in the condenser is cooled off fully, and the effect of bleeding is very obvious, has improved the degree of vacuum of unit operation.Use circulating water to replace soft water simultaneously, saved cost of electricity-generating.
Description of drawings
Accompanying drawing 1 is a jetting extract system schematic diagram of the present utility model.
Embodiment
