Description

A kind of absorption heat pump feedwater heat exchange cycle system
Technical field
The utility model belongs to a kind of absorption heat pump feedwater heat exchange cycle system, can improve feed temperature to the circulating water heat recovery, belongs to the generating energy technical field.
Background technique
The generating plant circulation-water UTILIZATION OF VESIDUAL HEAT IN has material impact to the Economy and the energy-saving and emission-reduction of unit, therefore is necessary circulating water waste heat system is studied.Existing circulating water bootstrap system, it mainly is that recirculated cooling water with low temperature extracts its Lowlevel thermal energy with heat pump techniques, by electric energy or thermal power transfer, phase transformation etc. heat energy is promoted to can be used for the clean energy resource of the demand of heating.This system is with vapour condenser circulating water (generally high about 10 ℃ than ambient temperature), promotes by heat pump techniques, and heated feed water improves feed temperature.
Summary of the invention
A kind of absorption heat pump feedwater heat exchange cycle system comprises absorption heat pump (1), recirculated cooling water (2), high temperature heat source (3), low-temperature condensate (4) composition, it is characterized in that: recirculated cooling water (2) and high temperature heat source (3) feed respectively in the absorption heat pump (1) and circulate, the output of acting back, low-temperature condensate (4) also feeds in the absorption heat pump (1), absorbs the heat output afterwards of recirculated cooling water (2) output.Present technique is used to improve existing residual heat heating this purpose, based on a kind of absorption heat pump heat exchange cycle system, provide a kind of new circulating water UTILIZATION OF VESIDUAL HEAT IN mode promptly to improve power plant's feed temperature, and then can reach the purpose that effectively utilizes the energy, thereby realize obvious energy-saving effect.
The utility model is realized by following technology:
A kind of absorption heat pump heat exchange cycle system, it mainly is made up of absorption heat pump, high temperature heat source, recirculated cooling water, low-temperature condensate.Native system is with high temperature heat source, and recirculated cooling water feeds absorption heat pump respectively and circulates, and acting back output is given the feedwater of condensing with the thermal energy transfer of the recirculated cooling water of low temperature, and feed temperature is promoted.
Above-mentioned absorption heat pump heat exchange cycle system, described absorption heat pump is made up of generator, condenser, vaporizer, cryogenic fluid pump, throttle valve, solution pump, adsorber, solution heat exchanger.
Above-mentioned absorption heat pump heat exchange cycle system, described high temperature driven thermal source is from the 5th section high-temperature steam that is extracted in the steam turbine set thermodynamic system.
Above-mentioned absorption heat pump heat exchange cycle system, described recirculated cooling water are the vapour condenser recirculated cooling waters.
Above-mentioned absorption heat pump heat exchange cycle system, described low-temperature condensate are the formed saturation waters of cooling under the turbine discharge level pressure.
Description of drawings
Fig. 1 is a system of the present utility model operational flow diagram; Fig. 2 is the heat flow diagrams of certain type steam turbine set.
Among Fig. 1,1 is absorption heat pump, and 2 is recirculated cooling water, and 3 is high temperature heat source, and 4 is low-temperature condensate.
Embodiment
High temperature heat source is from institute of power plant extracting high-temperature steam.Generator is driving heat source with steam, and adsorber and condenser series connection constitute the heating agent loop, and vaporizer absorbs heat to low level heat energy by the waste heat loop.Solution pump is discharged and is entered adsorber after dilute solution heats up through solution heat exchanger during operation, spray is in tube surface, absorbing becomes dilute solution behind the refrigerant vapour of from evaporator drier, and heating agent enters behind the adsorber and heats up for the first time behind the draw solution absorption process liberated heat.From the condensation on condenser bundles of generator refrigerant vapour, discharge condensation latent heat simultaneously and make that heating agent is heated once more and heats up in the pipe.Improve the water of condensation feed temperature by this process.
