Description
Technical field
The utility model belongs to vacuum equipment technical field, is specifically related to a kind of condenser of power station of taking out condenser vacuum system for generating set and vacuumizes and use water ring vacuum pump complexes.
Background technology
When generating set steam turbine admission warming-up, steam enters condenser, if condenser is not set up certain vacuum, steam enters condenser will make condenser form malleation, damage equipment.And condenser its inside in running is in vacuum state, due to pipeline and housing imprecision, air can leak people, thereby destroys condenser vacuum, unfavorable to Turbine Safety economical operation.Meanwhile, when air content is large, make the oxygen content of condensate water increase and aggravate equipment corrosion, two can increase heat transfer resistances, affect cooling effect for a moment.Therefore, generating set need to be set up condenser vacuum at the startup of unit initial stage, also needs to keep condenser vacuum in unit running process, guarantees the safety and economic operation of unit.At present, generating set steam turbine is vacuumized to operation and generally adopt injecting type air ejector, but conventional spray formula air ejector noise is large, the suction capactity of low vacuum is poor, can not meet the vacuum requirement of generation current unit operation.
Summary of the invention
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, provide the suction capactity of a kind of compact conformation, handling safety, low vacuum strong, the condenser of power station that operation energy consumption is low vacuumizes uses water ring vacuum pump complexes.
The utility model solves the technical scheme that its technical problem adopts: this condenser of power station vacuumizes uses water ring vacuum pump complexes, comprise water ring vacuum pump and vavuum pump drive motors, it is characterized in that: described water ring vacuum pump inlet end connects with upstream equipment suction inlet by access pipeline, exhaust end connects with gas-liquid separator, gas-liquid separator top is provided with exhaust outlet, bottom connects with the water supplement port of water ring vacuum pump by water return pipeline, and water return pipeline is provided with the heat exchanger for backwater cooling.The Compressed Gas that gas-liquid separator sucks water ring vacuum pump is discharged by exhaust outlet, the water of suction is returned and is filled in water ring vacuum pump by water return pipeline simultaneously, recycles.
Between described water return pipeline and access pipeline, be also provided with spray pipeline, spray pipeline is provided with condensation nozzle.When in access pipeline, compressed air temperature is too high, can to the suction Compressed Gas in access pipeline, lower the temperature by the condensation nozzle arranging on spray pipeline.
Described access pipeline is provided with butterfly valve and check-valves, and butterfly valve connects with control cabinet by circuit.When water ring vacuum pump system quits work, can upstream steam turbine equipment and water ring vacuum pump system be disconnected by butterfly valve and check-valves.
Described butterfly valve is Pneumatic butterfly valve or electric butterfly valve.
Condenser vacuumizes the vavuum pump configuration that adopts the using and the reserved, and while starting to vacuumize, two vavuum pumps move simultaneously;
At complete set of equipments air inlet end, pressure switch, differential pressure switch and pneumatic (or electronic) butterfly valve are housed.The effect of butterfly valve is that condenser system and pump assembly are separated.The effect of differential pressure switch is the open and close of controlling butterfly valve.When pump up moving after, before and after butterfly valve, just have pressure reduction, now generally differential pressure value is set as to 3 kPa, pressure reduction reaches after setting value, butterfly valve is opened, and directly aspirates condenser system.Pressure switch (passing through control cabinet) can control pump parking and starting, thereby realize, two pumps puts into operation and the automatic control of stand-by pump.It can be provided with 2 values of bound, by user, is set voluntarily, generally between 5--12 kPa, sets.
From heat exchanger cooling working water out, by the suction capacity of vavuum pump, Chu Yi road enters in pump, and another road water is through spray pipeline, by condensation nozzle, and can be to the steam-condensation sucking.In fact improved the exhaust capacity of pump.
Because height of liquid level in device is controlled: the liquid-level switch being bundled by liquid level gauge is controlled the switch of moisturizing magnetic valve, guarantees that liquid level is not less than low level-set point, automatic relief valve, the liquid level in assurance separator is not higher than high level-set point.
Complete set of equipments configuration control cabinet, it can by control element select vavuum pump manually, automatically, remote control puts into operation, realizes being connected of a whole set of vavuum pump unit and powerplant control room.
Compared with prior art, condenser of power station of the present utility model vacuumizes with the beneficial effect that water ring vacuum pump complexes have: 1) economical operation, under state of starting operating, the suction capactity of low vacuum, much larger than injecting type air ejector, shortens the starting time of unit greatly.Under running status, wasted work is only 23%～33% of water jet air ejector.2) loss of steam and water is less.3) pump group operation automaticity is high, handling safety, easy.4) noise is little, compact conformation, and floor space is little.
Accompanying drawing explanation
Fig. 1 is that the utility model condenser of power station vacuumizes with water ring vacuum pump complexes structural representation.
Wherein: 1, water ring vacuum pump 2, drive motors 3, gas-liquid separator 4, water return pipeline 5, heat exchanger 6, condensation nozzle 7, butterfly valve 8, access pipeline 9, check-valves 10, control cabinet 11, cooling water inlet 12, coolant outlet 13, suction inlet 14, exhaust outlet 15, working solution import 16, evacuation port.
