Description
Technical field
The utility model relates to a kind of two circulating phase-change cooling systems that are used for Hydropower Plant.
Background technology
Power station hydraulic generator unit is in running, not only the guide bearing of the top guide bearing of generator, thrust bearing and lower guide bearing and the hydraulic turbine can produce a large amount of heats, temperature raises, also can produce a large amount of heats between generator amature and the stator, and the heat that produces than the bearing place is more.The temperature at each bearing place of hydraulic generator unit raises, and the performance of bearing oil is reduced greatly, and the operational environment of bearing worsens, and the operate as normal of hydraulic generator will be affected.For bearing is worked under a home, need cool off bearing, the heat of generation in service is in time removed.Generator amature and stator should in time be removed the heat of generation in service too.The cooling of generator amature and stator is to be cooled off by the air that the circulation of the gap between generator amature and stator is passed, and air by the cooling of generator aerial cooler, is taken away heat again.To the conventional method that bearing and aerial cooler cool off, be that water or the cleaner water that attracted by spiral case or downstream tail water cool off before the dam of directly using through tentatively cleaning, after cooling water cooled off, directly discharging did not recycle.The place that this conventional method is the most not enough is, because cooling water constantly drains, be difficult to accomplish that the harmful substances such as aquatic organism in cooling water is softening, neutralization, the removing cooling water are handled, therefore, after operation a period of time, the cooling surface of bearing and air cooler can produce incrustation scale, assembles silt and multiplies aquatic organism, need often remove, could guarantee bearing and aerial cooler operate as normal, as untimely removing, can reduce cooling effect greatly, influence the operate as normal of hydraulic generator unit.For with before the not high dam of the degree of cleaning, spiral case, tail water directly cool off bearing and aerial cooler because impurity is many in the cooling water, sediment charge is big, the operate as normal of hydraulic generator unit is difficult to guarantee that operating cost is higher.
In order to overcome the deficiency of this water-cooled valve, have the Hydropower Plant cooling device that a kind of cooling water can be recycled now, cooling back installation is provided for oneself cooler, is placed the heat exchanger of tail water and pipeline to form by circulating water pool, circulating water pump, unit.This technology adopts the softening soft water of handling to make cooling water, the water fouling, the silt that have solved the heat generating components water cooling face of traditional water cooling means existence are assembled and problems such as aquatic organism multiplies, improved the unit operation reliability, significantly reduce operating cost, promoted the progress of Hydropower Plant cooling technology.But this Hydropower Plant circulating water cooling device also comes with some shortcomings.One, circulating water cooling system must dispose the circulating water pump that circulation power is provided, and operation consumes a large amount of electric energy; Its two, circulation is not a closed system, the material harmful to unit operation also might be entered in the recirculated cooling water by circulating water pool, the operation of harm cooling back installation, reliability is not high enough; Its three because the heat transfer efficiency of water is not very high, need to be equipped with the enough big heat exchanger of heat exchange area, the volume ratio of cooling device is huger.
Above-mentioned bearing and aerial cooler are carried out in the water-cooled prior art, the cooling water that is used for the aerial cooler cooling accounts for 80% of whole cooling water inflows, solve the cooling problem of aerial cooler, promptly solved the cooling operating cost problem of hydraulic generator unit substantially.Therefore, the cooling problem of solution generator aerial cooler is a matter of utmost importance.

By cooling water inlet and coolant outlet cooling water is imported to heat pipe condenser inside, cooling water cools off the steam state working medium that flows into condenser by the working substance steam riser, thereby steam state working medium generation condensation becomes liquid refrigerant mutually, reach cooling effect with this, and form an external refrigeration circulatory system.
When the circulating cooling system cooling that relies on Working fluid phase changing heat absorption and heat radiation is also adopted in the bearing cooling of hydraulic generator, the working substance steam riser of each heat pipe evaporator of cooling different heat parts, be connected with heat pipe condenser again after can adopting evaporator working substance steam riser with at least two places to converge, be connected with heat pipe condenser again after preferentially selecting whole evaporator working substance steam risers met at a working substance steam riser.Equally, the working medium condensate descending that connects each heat pipe evaporator, can adopt to be connected with heat pipe condenser again after the evaporator working medium condensate descending at least two places converged, be connected with heat pipe condenser again after equally also preferentially selecting whole evaporator working medium condensate descending met at a working medium condensate descending.
The utility model also comprises water cooling system.The thrust bearing water cooler that described water cooling system mainly is connected with cooling device by cooling device and by recirculated cooling water water inlet pipe and cooling water return pipe or/and the guide bearing water cooler constitute.
