Abstract
The utility model provides a kind of evaporation-cooled device of stator of steam turbine generator, and its main points are: condenser is placed on above airtight evaporative cooling chamber; Said condenser is that cooling water pipe passes condensation chamber, forms heat exchanger; Stator heat generating components is immersed in the liquid cooling medium of evaporative cooling chamber, and the ullage of liquid cooling medium is evaporating space; Fill unidirectional valve group between bottom evaporating space and condensation chamber, the direction of unidirectional valve group only allows the steam of evaporating space to enter in condensation chamber through unidirectional valve group; Between condensation chamber and evaporative cooling chamber, establish fluid infusion case, arrange communicating pipe between two adjacent settings, what be wherein arranged on condensation chamber is arranged on condensation chamber sidewall bottom communicating pipe.Good effect of the present utility model is: because it have employed vapor cooling system, considerably improve cooling-down effect.
Description
Technical field
The utility model relates to a kind of evaporation-cooled device of stator of steam turbine generator.
Background technology
The cooling device of current stator of steam turbine generator is water-cooling cooling device, this water cooling plant is from becoming an independently closed cycle system, water in water tank is extracted out by water pump, feeding water cooler is lowered the temperature, then through filter except the mechanical impurities in anhydrating, by entering respectively after air deflector in hollow conductor in steam turbine stator bar and lead-in wire stator outlet casing tube.After cooling water is lowered the temperature to stator in hollow conductor, high-temperature water by non-return valve reflow tank, realizes whole cooling procedure again.Water cooling plant cooling effectiveness is low.
Summary of the invention
For solving the low problem of water cooling plant cooling effectiveness, the purpose of this utility model is to provide a kind of evaporation-cooled device of stator of steam turbine generator.
The purpose of this utility model is achieved in that it comprises generator unit stator heat generating components, it is characterized in that: condenser is placed on above airtight evaporative cooling chamber; Said condenser is that cooling water pipe passes condensation chamber, forms heat exchanger; Stator heat generating components is immersed in the liquid cooling medium of evaporative cooling chamber, and the ullage of liquid cooling medium is evaporating space; Fill unidirectional valve group between bottom evaporating space and condensation chamber, the direction of unidirectional valve group only allows the steam of evaporating space to enter in condensation chamber through unidirectional valve group; Between condensation chamber and evaporative cooling chamber, establish fluid infusion case, arrange communicating pipe between two adjacent settings, what be wherein arranged on condensation chamber is arranged on condensation chamber sidewall bottom communicating pipe.
Logical cooling water in cooling water pipe.Stator heat generating components generates heat, and the liquid cooling medium of evaporative cooling chamber is heated vaporization, and its density is less than pure liquid medium, density contrast under acceleration of gravity effect, generation flow head.Steam rises to above evaporative cooling chamber, condenser is entered through unidirectional valve group, condensation after exchanging with cooling water pipe, condensation chamber bottom is fallen to the form of drop, liquefy coolant, communicating pipe returning evaporative cooling chamber through two sections successively again, is the cooling of stator heat generating components, the process of the formation evaporative cooling self-loopa that so goes round and begins again.
Compared with prior art, good effect of the present utility model is: because it have employed vapor cooling system, considerably improve cooling-down effect.
Accompanying drawing explanation
The utility model is further illustrated below in conjunction with accompanying drawing.
Fig. 1 is schematic diagram of the present utility model.
Embodiment
