Description
Technical field
The present invention relates to a kind of thermoelectric combined heating system, be applicable to more energy-conservation, the safely and reliably utilization of cogeneration power plant steam turbine exhaust steam, heat network system more utilizes condensation waste heat.
Background technology
Along with the shortage of the energy and the requirement of energy-saving and emission-reduction improve day by day, the comprehensive utilization technique of the energy is in continuous lifting.North City planning cogeneration carries out central heating, to substitute original independent boiler central heating, realizes the requirement of energy-saving and emission-reduction.Take full advantage of steam power plant's used heat, to improve the heat capacity of steam power plant, realize better energy-saving and emission-reduction, guarantee again the safe and reliable operation of steam power plant and heat supply network simultaneously, various new flow processs require study.Realize the more turbine discharge used heat that reclaims in the power plant, the most important condition is with the secondary network return water temperature reduction of hot user side, adopts on this basis the source pump take electricity as power, or the absorption type heat pump assembly take the heat supply network high-temperature water as power.Carry out refrigeration cool-down by the heat supply network backwater that power plant is confessed, as the waste heat source of heat pump again for secondary network, the heat supply network return water temperature is reduced after telegram in reply factory.Power plant's heat supply network backwater is introduced into former plant condenser after entering power plant, with electric power plant circulating water be blended in the condenser heat up after, enter again absorption heat pump, send after in heat pump, heating up.In this system, the temperature that recirculated water goes out heat pump be heat supply network in the key of the many recovering condensing heats of whole Heating Season, in same outlet temperature, can reclaim more condensation waste heat, and become the another difficult problem of steam power plant's central heating technology with high-grade drawing gas less.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, a kind of condensation waste heat of realizing reclaiming more steam power plants is provided, the operational efficiency of raising heat pump and heat network system be the circulating-water tandem of reliability service more.
The object of the present invention is achieved like this: a kind of circulating-water tandem, comprise sucking condensing turbine, extracted steam from turbine pipe, water-cooled condenser, vapor-water heat exchanger and absorption heat pump, described absorption heat pump has the n platform, n is 〉=2 natural number, and high steam is extracted part steam out as the thermal source of absorption heat pump and vapor-water heat exchanger after sucking condensing turbine work done generating.Exhaust steam in steam turbine condenses into water by condenser, and condensation waste heat is recycled.Described absorption heat pump has additional subcooler, the heat supply network backwater is divided into the absorber that two tunnel: one road heat supply network backwater is introduced into the First absorption heat pump after entering power plant, enter again the absorber of second absorption heat pump ... be connected in series successively, until enter the absorber of n platform absorption heat pump, the absorber that goes out n platform absorption heat pump enters the condenser of this n platform absorption heat pump again, then from n-1, n-2 ... be connected in series successively, the condenser from the First absorption heat pump flows out at last; Another road heat supply network backwater parallel connection enters the subcooler of each absorption heat pump, and two road heat supply network backwater merge at last, directly or again send behind vapor-water heat exchanger; The cooling circulating water of water-cooled condenser goes out the evaporimeter that is introduced into n platform absorption heat pump behind the described water-cooled condenser, then return successively, enter at last the evaporimeter of second absorption heat pump, First absorption heat pump, after the evaporimeter outflow of First absorption heat pump, enter the cooling system of steam power plant.
Circulating-water tandem of the present invention, the cooling system of described steam power plant are cooling tower or a device for cooling.The cooling system of steam power plant also can be that air and water-cooled condenser water outlet indirect heat exchange enter atmosphere with heat.
Circulating-water tandem of the present invention, the subcooler of described each absorption heat pump is merged into a subcooler, subcooler after this merging of the water as refrigerant pipeline of each absorption heat pump access in parallel, subcooler and another road heat supply network backwater that the heat supply network backwater goes out after this merging merge at last.
Cold power plant between this circulating-water tandem also is applicable to.
The invention has the beneficial effects as follows:
Absorption heat pump in steam power plant has increased when subcooler is done heat supply for heat supply in winter season and has moved.Heat supply network recirculated water and power plant's cool cycles water separation isolated operation.Guaranteed the water quality of hot net water, guaranteed that all kinds of heat transmission equipments can safe and reliable energy-efficient operation.And because cooling circulating water and condensing direct heat transfer, compare with employing cellular-type heat-exchange system and can reclaim used heat more.Adopt heat supply network recirculated water directly to reclaim the COP value that the heat pump waste heat has more effectively improved heat pump.The working steam of heat pump will be saved more than 8% than original system.Because heat pump has been used high-grade energy less in reclaiming steam power plant's condensation waste heat process, so compare with former heat pump, in the situation that reclaims same condensation waste heat, the temperature that goes out heat pump is lower than originally, can guarantee that so more heat supply network recovering condensing heat amount when heating demand descends realizes maximization, is used for heating at the more exhaust steam in steam turbine of whole Heating Season utilization.On the other hand, owing to reclaim same condensation heat, the circulating water temperature that goes out heat pump is low, in same outlet temperature situation, and the recyclable more condensation waste heat of heat pump.By heat supply network recirculated water and cooling circulating water corresponding series flow in the absorber of each heat pump and condenser and evaporimeter, the performance of heat pump is better optimized.The volume of heat pump, weight indicator can descend greatly, and manufacturing cost can descend simultaneously.On the other hand, because the performance optimization of heat pump, every economic technology economic indicator of steam power plant is further enhanced.
