Description

Residual heat of electric power plant utilizes heating system combination technique device
Technical field
The utility model relates to a kind of heating system device, is specially a kind of utilization " residual heat of electric power plant utilizes heating system combination technique device ".
Background technology
Steam turbine generator is the heat energy of high pressure-temperature (or medium temperature and medium pressure) steam that boiler is produced, is converted into the electric energy of mechanical energy and generator through rotor, after high pressure-temperature (or medium temperature and medium pressure) steam is finished mechanical power; Become waste vapour and enter the condenser heat release, by the cooling water heat absorption that water circulating pump provides, water circulating pump links to each other with cooling tower; Perhaps steam discharge gets into the aerial cooler heat release; In this process, steam discharge gets into condenser or aerial cooler heat release, and waste vapour becomes condensate and discharges great amount of heat; Deliver in the cooling tower or steam discharge dispels the heat in aerial cooler by recirculated cooling water; Heat constantly distributes and loses then, and the boiler design smog discharge temperature is about 135 ℃ simultaneously, also causes a large amount of loss of fume waste heat and waste.No matter be boiler exhaust gas; Still turbine discharge in fact all is the waste and the loss of heat, and the utility model technology is through the art designs of reasonable combination; Turbine discharge waste heat and fume afterheat are recycled effectively, significantly increased concentrated supply of heating in the city.
Summary of the invention
The utility model combination technique has solved the used heat of electricity (or thermoelectric) factory steam turbine discharge and the flue gas heat of boiler emission fully utilizes; Central heating provides heat supply to the city; Its principle is to coagulate water-circulating pump to pass through a pipe network recirculated water through condenser, absorption heat pump, heat pipe flue gas water-to-water heat exchanger, vapor-water heat exchanger, a pipe network recirculated water heating, again through water water-to-water heat exchanger and absorption heat pump; The hot user's circulation water for heating heating of secondary net, realize concentrated supply of heating in the city.
A kind of residual heat of electric power plant utilizes heating system combination technique device, is applicable to air cooling, clammy unit, it is characterized in that: condenser (4) is connected with absorption heat pump (7); Absorption heat pump (7) is connected with condensed water circulating pump (8); Condensed water circulating pump (8) is connected with condenser (4); Filter (20) with once net water circulating pump (21) and be connected; Once netting water circulating pump (21) is connected with absorption heat pump (7); Absorption heat pump (7) is connected with heat pipe flue gas water-to-water heat exchanger (11); Heat pipe flue gas water-to-water heat exchanger (11) is connected with vapor-water heat exchanger (13); Vapor-water heat exchanger (13) is connected with absorption heat pump (15); Absorption heat pump (15) is connected with water water-to-water heat exchanger (16); Secondary net water circulating pump (23) is connected with absorption heat pump (15), water water-to-water heat exchanger (16) respectively through hot user's return pipe.
The beneficial effect of the utility model is: effectively utilized waste heat and fume afterheat that steam turbine is discharged, realized the heat supply of winter to hot user, in energy savings, reduced environmental pollution and improve urban environment, improved the quality of residents'life level.
This utility model " residual heat of electric power plant utilizes heating system combination technique device ", and have the low advantage of operation cost, so popularizing application prospect is very extensively.
