Abstract
The utility model relates to a water-jet steam extraction cooling system for a steam turbine, which comprises a circulating water pond, a condenser, a water-jet pump, a water-jet steam extraction device, a water-jet box and a heat exchanger, wherein the water inlet/outlet pipe of the condenser is communicated with the circulating water pond; the water inlet/outlet pipe of the water-jet pump is communicated with the water-jet box; the water outlet of the water-jet pump and the extraction pipeline of the condenser are communicated with the inlet of the water-jet steam extraction device; the heat exchanger is arranged in the water-jet box; and the inlet/outlet of the heat exchanger is communicated with an external cooling medium pipeline. As the water-jet steam extraction device utilizes an external cooling medium, the water temperature of the water-jet box is reduced, the efficiency of the steam extraction device is greatly improved, the steam extraction effect is very obvious, the operating vacuity of the machine set is improved, and meanwhile the water replenishing quantity of the water-jet box and the power generation cost are reduced.
Description
Technical field
The utility model belongs to the steam turbine technology field, especially a kind of jetting of steam turbine cooling system that draws gas.
Background technique
Traditional steam turbine jetting vapor extractor system uses industry water or softened water, and the rate of water make-up specific consumption is bigger; And, influence jetting vapor extractor effect because water temperature than higher, operates between 50-60 ℃ at ordinary times; Condenser vacuum is low when causing unit operation, and unit efficiency descends, and this situation is especially particularly outstanding under continuous high load running; Therefore designing a kind of jetting vapor extractor cooling system, is the problem that needs solution at present.
The model utility content
The purpose of the utility model is to overcome the shortcoming of above-mentioned existing technology, and a kind of jetting of the steam turbine cooling system that draws gas is provided, and this system utilizes cooling medium to reduce jetting case water temperature, and unit efficiency is risen.
The purpose of the utility model solves through following technological scheme:
The jetting of this steam turbine cooling system that draws gas comprises circulating water pool, vapour condenser, water-jet pump, jetting formula vapor extractor, jetting case and heat exchanger, and the turnover water pipe of said vapour condenser is communicated with circulating water pool, and the turnover water pipe of said water-jet pump is communicated with the jetting case; The water outlet of said water-jet pump and the pump-line of vapour condenser are communicated with the import of jetting formula vapor extractor, and said heat exchanger is arranged in the jetting case, the import and export of heat exchanger and extraneous cooling medium pipeline UNICOM.
Further, jetting case moisturizing valve is set on the moisturizing pipeline of jetting case.
Further, on the pipeline between circulating water pool and the vapour condenser, valve is set.
Compared with prior art, the utlity model has following beneficial effect:
The utility model jetting vapor extractor uses extraneous cooling medium, has reduced jetting case water temperature, and vapor extractor efficient is greatly improved; The effect of bleeding is very obvious; Improve the degree of vacuum of unit operation, jetting case rate of water make-up is reduced, practiced thrift cost of electricity-generating.
Description of drawings
Fig. 1 is the device connection diagram of the utility model.
Wherein: 1 is circulating water pool; 2 is vapour condenser; 3 is jetting formula vapor extractor; 4 is the jetting case; 5 is heat exchanger; 6 is water-jet pump; 7 is valve.
Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:
Referring to Fig. 1, the jetting of the utility model steam turbine cooling system that draws gas comprises circulating water pool 1, vapour condenser 2, water-jet pump 6, jetting formula vapor extractor 3, jetting case 4 and heat exchanger 5.Wherein the turnover water pipe of vapour condenser 2 is communicated with circulating water pool 1, and the turnover water pipe of water-jet pump 6 is communicated with jetting case 4; The pump-line of the water outlet of water-jet pump 6 and vapour condenser 2 is communicated with the import of jetting formula vapor extractor 3, and heat exchanger 5 is arranged in the jetting case 4, and the import and export of heat exchanger 5 are communicated with extraneous cooling medium pipeline.Water in the jetting case 4 can fully obtain cooling like this, and it is lower that water temperature keeps always.In addition, jetting case moisturizing valve also is set on jetting case 4 moisturizing pipelines.Jetting case moisturizing valve is set on the moisturizing pipeline of jetting case 4, on the pipeline between circulating water pool 1 and the vapour condenser 2, valve 7 is set.
