Abstract
The utility model discloses a system capable of improving the generating efficiency of a power plant through an absorption heat pump. The system is characterized in that the low-temperature vapour discharged by a steam turbine after power generation enters an evaporator of the absorption heat pump, and the evaporator replaces part of the function of a cooling tower and condenses the low-temperature vapour into water; and the low-temperature vapour enters an absorber and a condenser of the absorption heat pump simultaneously to raise the temperature of the low-temperature vapour, then high-temperature vapour pumped out through the steam turbine is used to raise the temperature of the low-temperature vapour, and when the low-temperature vapour reaches the standard water temperature and water pressure for entering a steam boiler, the low-temperature vapour enters the steam boiler in a circular manner. The system has the advantages that through the high efficiency work of the absorption heat pump, part of the function of the cooling tower is replaced, and through the process of condensing the low-temperature vapour into water, the residual heat of the cooling tower is recycled, the need for vapour of the heating water temperature section of the absorption heat pump is reduced, and the generating efficiency is indirectly improved.
Description
Technical field
The utility model belongs to the Turbo-generator Set field, the Low Temperature Steam that refers more particularly to the steam turbine generator boiler circuit pressurization link of heating.
Background technique
The thermal power plant along with the minimizing of fossil class A fuel A reserves, causes energy prices to rise steadily take fire coal as main.Under the prerequisite of the existing energy, how to improve generating efficiency, be the key point that can the thermal power plant be survived.Country encourages the dynamics of new energy development constantly to strengthen, and causes various energy-conserving products to emerge in an endless stream, and various energy-saving and water-saving products arise at the historic moment, and heat pump techniques is the new energy technology that receives much attention in the whole world in recent years." heat pump " is a kind ofly can obtain low grade heat energy from natural air, water or soil, through the electric power acting, providing can be by the device of the used high-grade heat energy of people, its Energy Efficiency Ratio is much larger than 1, the heat that namely provides heat that a fuel produces will produce much larger than direct burning by acting.
In the technological process of steam turbine generator boiler circuit, water flashes to steam after heating in boiler, through continuing the heating pressurization, forms the superheated vapor with certain pressure and temperature, then enters steam turbine through piping.In steam turbine, the steam expansion flow at high speed, the thermal power transfer that the drive steam turbine rotates hot steam becomes mechanical energy, and the drive generator generating coaxial with steam turbine.In inflation process, the pressure and temperature of steam constantly reduces, and enters cooling tower from the steam turbine discharge after the acting, and cooling tower condenses into synthermal water by the cooling water effect with low temperature and low pressure steam.Water of condensation extracts the pressurization of steam Multi-stage heating by steam turbine, returns boiler, finishes the power generation cycle of water-steam-water.
In this circulation, water of condensation realizes that by the steam that extracts in the steam turbine technique of heating pressurization has a lot of deficiencies.Other extracts steam turbine also affects generating efficiency to some extent for the steam that generates electricity, and therefore is condensed into water of condensation and the link of the pressurization of heating at Low Temperature Steam, quotes sorption type heat pump and makes suitable modification.
Summary of the invention
In order to improve the power station generating efficiency, the utility model provides a kind of system that improves the power station generating efficiency by absorption heat pump: go out steam port at steam turbine absorption (lithium bromide) heat pump is installed, replace the cooling Low Temperature Steam devices such as original condensate pump and vapour condenser cooling tower.The absorption heat pump end connects secondary heating pressurizer again.
The utility model by the concrete technological scheme that absorption heat pump improves the system of power station generating efficiency is: the generating of steam boiler driving steam turbine, Low Temperature Steam access heat exchanger after the generating, steam part after the heat exchanger heat exchange is linked into the evaporator end of absorption heat pump, again gets back in the heat exchanger through the steam behind the vaporizer displacement heat; Water vapor access adsorber in the vaporizer, adsorber connects the LiBr solution heat exchanger, the LiBr solution heat exchanger is connected to generator, the steam that generator is extracted by steam turbine is as high temperature heat source, the high-pressure water vapor that generator produces is linked in the condenser, another part Low Temperature Steam after the heat exchanger heat exchange is linked into the adsorber end of absorption heat pump simultaneously, heat after the adsorber heat release directly is linked in the condenser, last condenser will reach in the water vapor access steam boiler of standard water warm water pressure, finish circulation.
The beneficial effects of the utility model are: by the efficiency operation of absorption heat pump, improved water of condensation and realized the technique that heating is pressurizeed by the steam that extracts in the steam turbine, reduced the loss that is used for the steam of generating, improved the efficient of generating.
