The steam ejector is communicated with a unit turbine or a steam source pipeline of a system where the condenser is placed. The condenser vacuum sucking device has the advantages of being stable and reliable to operate, efficient in energy saving and good in sucking effect.
Description
Technical field
The utility model relates to condenser, relates in particular to a kind of condenser vacuum aspirator.
Background technology
The condenser of generating set inside in running need remain vacuum state, but so condenser vacuum system cannot seal completely and must have a small amount of air to enter condenser inside, cause condenser inside to accumulate a certain amount of incondensable gas, the existence of incondensable gas will cause the cooling heat transmission situation of steam in condenser to worsen, be that recirculated cooling water significantly reduces the heat exchanger effectiveness of steam, the vacuum in condenser declines.
Incondensable gas in condenser is extracted out and is discharged in atmosphere and realizes by the equipment of drawing gas again, and the equipment of drawing gas extensively adopting is at present water-ring vacuum pump.
The working water of water-ring vacuum pump is normally come cooling with recirculated water or opened water, the temperature of working water is subject to directly affecting of environment temperature, work water temperature is larger to the influence on system operation of vavuum pump, practice shows, when the work water temperature of water-ring vacuum pump surpasses 30 ℃, the suction capactity of vavuum pump starts to occur decline in various degree, main cause is that the pressure of vavuum pump internal suction mouth is lower than 30 ℃ of corresponding saturation pressures, the local appearance vaporization of working water of pump inside, causes the suction capactity of pump to decline.Summer environment temperature higher while causing vavuum pump water temperature higher, need to start a vavuum pump operation more, or carry out the transformation of vavuum pump cooling water, meet the needs that improve condenser vacuum in real time execution; In addition, working water vaporization also can make the service condition of vavuum pump inside worsen, and cavitation in various degree occurs impeller, causes the faults such as crackle of impeller when serious.
Utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, provides that a kind of working stability is reliable, efficient energy-saving and the good condenser vacuum aspirator of suction effect.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of condenser vacuum aspirator, comprise the water-ring vacuum pump being communicated with described condenser, described condenser vacuum aspirator also comprises and is arranged between described condenser and described water-ring vacuum pump and the steam jet ejector being communicated with described condenser and water-ring vacuum pump respectively, and described steam jet ejector is communicated with power generator turbine or the steam source pipe road of described condenser place system.
Described condenser vacuum aspirator also comprises injector Control Component.
Described steam jet ejector exit is provided with cooler.
Compared with prior art, the utility model has the advantage of:
Condenser vacuum aspirator of the present utility model, comprise the water-ring vacuum pump being communicated with condenser, condenser vacuum aspirator also comprises and is arranged between condenser and water-ring vacuum pump and the steam jet ejector being communicated with condenser and water-ring vacuum pump respectively, steam jet ejector is communicated with power generator turbine or the steam source pipe road of condenser place system, condenser vacuum aspirator of the present utility model utilizes the advantage that the steam jet ejector amount of drawing gas is large, poor in condenser tightness, or the higher inner vaporization that exists of water-ring vacuum pump work water temperature, when cavitation phenomenons and suction capactity are not enough, improve the pump gas ablity of whole system, keep and improve the vacuum of condenser, incondensable gas in assurance condenser is discharged in time, improve the heat-transfer effect of condenser inside, to reach the object that improves unit overall thermal economy, working stability is reliable, efficient energy-saving and suction effect are good, adopt steam jet ejector, can improve the inlet pressure of water-ring vacuum pump, improve the service condition of water-ring vacuum pump, the cavitation phenomenons existing while avoiding water-ring vacuum pump isolated operation, reduce vibration and the noise of water-ring vacuum pump, extend the service life of water-ring vacuum pump, reduce Maintenance and Repair expense.
