Description
Technical field
The utility model relates to Hydropower Plant Study on Cooling field, particularly relates to the economizer pressure pipeline condensing unit of a kind of power station Phase cooling.
Background technology
Hydropower Plant, in running, can give out a large amount of heats.These heats must be taken away unit, and the operation that unit could be safe and reliable, the object that machine set technology supplies water takes away these heats exactly.
Technical water supply mode conventional at present has traditional penstock water intaking, and tail water is fetched water, and fetches water in forebay, and the recirculation refrigerating technology that top cover water intaking etc. and recent two decades extensively use supplies water and plate type heat exchanger hydrotechny.
During conventional art supplies water, no matter adopt which kind of mode, its water source is all river, and water quality is uncontrollable, especially flood season, and water quality cannot meet the service requirement of unit at all.In flood season, river floating thing is many, can cause the blocking of intake, discharge reduction, and unit temperature raises, and needs maintenance down; After silt in river enters unit, can cause wearing and tearing to the copper pipe of each cooler of unit, reduce unit durability, even the worn out copper pipe of possibility, causes potential safety hazard to unit; The mud of river, dirt are attached on the inside pipe wall of unit cooler, add thermal resistance, and cooling effect is deteriorated, and area of passage also can be caused to reduce, inflow-rate of water turbine is reduced, also can block cooling tube what is more; On the runoff of glacier snow melt supply, summer, river temperature was low, larger with the temperature difference that the humidity of factory building is larger, after river enters factory's interior conduit, pipeline is condensed, causes ground in factory to bear water, cause to repair and maintenance personnel constant greatly, meanwhile, moist factory building also can bring potential safety hazard to equipment; What sand erosion caused burn, and bearing shell shuts down, lubrication oil enters korneforos polluted river, is unfavorable for environmental protection.
Because traditional technical water supply exists above variety of problems, recirculation refrigerating technology hydrotechny is arisen at the historic moment.The water source of this technology is recirculated water, and water quality can manual control, thoroughly solves quality problem.The operation principle of this system is heat exchange principle.This system is made up of circulating water pool, water circulating pump, each cooler of unit, tail water cooler, pipeline, valve and Automation Elements.Water circulating pump draws water from circulating water pool and enters tail water cooler, then to unit, cooling water gets back to circulating water pool after absorbing unit heat; Pump it to tail water cooler by water pump again, in tail water cooler, get back to unit after cooling.This technology thoroughly can solve quality problem, but needs water pump to provide power, consumes station service more.
The Two-way Cycle plate type heat exchanger of external employing, plate type heat exchanger needs to be arranged in factory building, takies hall space; Need two cover water pump systems to provide power for whole system, power consumption is large; River is taken from the cold water side water source of plate type heat exchanger, affects larger by quality of river water; The cold water side draining of plate type heat exchanger directly drains into river, also can cause certain influence to environment.
Wherein, circulating cooling device for unit of hydroelectric station of the prior art utilizes the power of loss as whole system of unit completely, does not need pond and water pump.This system is made up of each cooler of unit, cooling working medium, condenser and Automation Elements.First whole system is vacuumized, then in unit cooler, add working medium to design attitude.Start.After unit operation, the heat that working medium absorbs unit becomes gas, rises to the condenser being arranged in generator floor, and cooled water cooling becomes liquid within the condenser, gets back to each cooler of unit by deadweight.This technology thoroughly solves the quality problem that machine set technology supplies water; and utilize the heat of unit to provide power for whole system completely, without the need to water pump, farthest save and see station service; this system can not outwardly discharge any noxious material simultaneously, is a kind of technology of very environmental protection.But the condenser of this technology is arranged in factory building, temporary hall space, need to introduce clean cooling water to condenser, this all cannot realize in a lot of power station simultaneously.
In sum, present inventor, in the process realizing utility model technical scheme in the embodiment of the present application, finds that above-mentioned technology at least exists following technical problem:
In the prior art, condenser due to existing circulating cooling device for unit of hydroelectric station is arranged in factory building, take hall space, need to introduce clean cooling water to condenser simultaneously, this all cannot realize in a lot of power station, so circulating cooling device for unit of hydroelectric station existence of the prior art takes up room larger, and need to introduce clean cooling water to condenser, use inconvenient technical problem.
