Description
Technical field
The utility model belongs to Turbine Cold Junction efficiency enhancing techniques field, relates to a kind of water chiller exhaust steam shunting spike cooling system.
Background technique
Along with global warming, thermal power plant generation load is affected by environment increasing, in the season that temperature is higher, the cooling tower that cooling tower poor effect, the particularly time limit is longer, because filler is aging, distribution pipe fouling, recycle pump undercapacity etc. cause cooling effectiveness to reduce, and unit back pressuce raises, and reduce unit generation efficiency, even summer peak of power consumption can not completely send out, considerably increase gross coal consumption rate.Coal, as non-renewable resources, with regard to national conditions, although CHINESE COAL reserves enrich, has one day that is finished sooner or later.Therefore be the strategy of sustainable development of response country, power industry need be sparing in the use of coal, and to respond national policy, exchanges a large amount of non-renewable resources for a small amount of renewable resources.And the circulating water in power plant can quote municipal middle water, industrial wastewater carries out secondary utilization.As can be seen here, gross coal consumption rate is reduced imperative.
Model utility content
The utility model, in order to solve the problems of the technologies described above, provide a kind of water chiller exhaust steam shunting spike cooling system, improves cooling effectiveness and generating efficiency, reduce unit back pressuce, thus reduce gross coal consumption rate.
The utility model is achieved through the following technical solutions:
A kind of water chiller exhaust steam shunting spike cooling system, comprise steam turbine, the exhaust steam outlet point two-way of described steam turbine, two-way is connected with the exhaust steam entrance of the second vapour condenser with the first vapour condenser respectively, an outlet of the first vapour condenser is connected with the entrance of mechanical force cooling column, the outlet of mechanical force cooling column is connected with the cooling entrance of the first vapour condenser after circulating water pump, an outlet of the second vapour condenser is connected with the entrance of cooling tower, the outlet of cooling tower is connected with the cooling entrance of the second vapour condenser after circulating water pump, the water of condensation outlet of the first vapour condenser and the second vapour condenser is after the condensation pump on respective pipeline, merge into water of condensation to flow out from condensation jellyfish pipe.
The exhaust steam outlet point two-way of described steam turbine, two-way exhaust steam flows into the exhaust steam entrance of the first vapour condenser and the second vapour condenser respectively through the extraction line be connected with steam turbine.
Compared with prior art, the utility model has following useful technique effect:
The water chiller exhaust steam shunting spike cooling system that the utility model provides, by extracting a part of exhaust steam out in turbine discharge outlet, after exhaust steam shunting, vapour condenser is entered by extraction line, after heat exchange in vapour condenser cools, be condensed into water of condensation through circulating water, water of condensation enters condensation jellyfish pipe by condensate pump.Circulating water after heat exchange enters vapour condenser heat exchange through circulating water pump again after being dispelled the heat by mechanical force cooling column.Like this, by extracting a part of exhaust steam out in turbine discharge outlet, neither affecting the normal operation of original system, only reducing the heat exchange load of former cooling tower, realized the shunting cooling condensation of exhaust steam in steam turbine by this cooling system.
Meanwhile, original cooling-tower circulating water amount is constant, but heat exchange amount reduces, and circulating water temperature reduces, and the temperature that circulating water enters vapour condenser also can reduce, and the heat transfer effect of circulating water in vapour condenser strengthens, and turbine back pressure reduces, and reduces gross coal consumption rate.
The utility model, for the high problem of domestic thermal power generation unit coal consumption, for cost-saving, reduces coal resources waste, increase economic efficiency, realizing the shunting cooling condensation of exhaust steam in steam turbine by increasing mechanical force cooling column, reducing the heat exchange load of original cooling tower, not affecting on the basis of original system, greatly improve unit cooling effectiveness, reduce unit back pressuce, final realization reduces gross coal consumption rate, cost-saving, reduce airborne release, reach the two receipts of ecnomics and enviroment benefit.
