Description
Technical field
The utility model relates to a kind of absorption type heat pump heating apparatus, particularly reclaims the absorption type heat pump heating apparatus of the fume afterheat of combustion and steam cycling hot power plant.
Background technology
Because natural gas, coal gas or wet goods gas, liquid fuel can produce a large amount of water in burning, so, a large amount of water vapours contained in the waste heat boiler discharged flue gas of gas-steam combined cycling hot power plant.Have a kind of condenser boiler that utilizes the vapour latent heat that waste heat boiler discharges at present, it is by a condensing heat exchanger, by the cold working medium of outside need heating with the water vapour condensation in the flue gas.Therefore the use of this condensing boiler need temperature enough low be heated cold working medium, make flue-gas temperature reach the condensation temperature of steam.But the waste heat boiler of gas power device, the condensation temperature of steam is very low in the flue gas, therefore, for reaching the purpose that reclaims vapour latent heat in the flue gas, needs the lower cold working medium that is heated of temperature that flue gas is cooled off.And in field of heating,, often can't make flue gas reach due condensation temperature because the heating return water temperature is higher generally speaking.So this condenser boiler is difficult in the field of heating to be promoted the use of.
Summary of the invention
At problems of the prior art, the utility model provides a kind of absorption type heat pump heating apparatus that reclaims gas-steam combined circulating thermoelectric plant smoke residual heat, can provide temperature enough low cooling working medium for the waste heat boiler of gas-steam combined cycling hot power plant, can recycle the condensation heat of steam again.
A kind of absorption type heat pump heating apparatus that reclaims the fume afterheat of combustion and steam cycling hot power plant, comprise absorption heat pump, heat exchanger, waste heat boiler, gas power device, condenser, steam turbine and tube connector, described absorption heat pump comprises generator, solution heat exchanger, absorber, pump, evaporimeter, condenser; Its characteristics are that described evaporimeter places in the boiler, the parallel smoke pipe bundle that is provided with in the evaporimeter, and the steam turbine blast pipe passes through generator.
According to technique scheme, to be arranged on the part in the generator be the snake type to the steam turbine blast pipe in the described device.
The utility model is with the boiler combination of absorption heat pump and gas-steam combined cycling hot power plant, make full use of the vapour latent heat in the exhaust-heat boiler flue gas, promptly solved the required low-temperature heat source of absorption type heat pump operation in the prior art, the efficient of gas-steam combined cycling hot power plant is greatly improved on original basis.Owing to had the low-temperature heat source of higher temperature, promptly make the absorption heat pump operating efficiency be improved significantly, energy consumption reduces greatly; And water has also absorbed pernicious gases such as the part NOx in the flue gas, SOx with fixed attention, and the discharge of harmful gases amount is reduced significantly, helps environmental protection.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, absorption heat pump comprises generator 1, solution heat exchanger 2, absorber 3, pump 4, evaporimeter 5, condenser 7 and tube connector.Absorber 3 and condenser 5 polyphones or formation hot-water return in parallel heat supply.Working media also has the absorbent that absorbs, resolves cold-producing medium except that the cold-producing medium of producing cold, it is right that the two forms working medium.Working medium parses refrigerant vapour-vaporized refrigerant to being heated by the high temperature heat medium in generator 1, and the condensation in condenser 7 tube bank of this refrigerant vapour discharges condensation latent heat simultaneously and the hot water in the pipe is heated.Condensed cold-producing medium evaporates in evaporimeter 5 and absorbs heat to low-temperature heat source.High concentration absorbent process solution heat exchanger 2 continuous refrigerant vapour that absorbs from absorber 3 in absorber 3 from generator 1, absorbent is emitted heat and is heated the hot water of the evaporimeter 5 of flowing through in absorbing the refrigerant vapour process, absorbent is got back to generator 1 through pump 4 and solution heat exchanger 2 then.Be heated the heat that hot water absorbs and equal generator 1 high temperature heat source liberated heat and evaporimeter 5 low-temperature heat source liberated heat sums in absorber 3 and condenser 7.
Combustion gas, fuel oil work by combustion in gas power device 12 is also generated electricity by generator 11-1, described evaporimeter 5 places in the boiler 8, flue gas in the boiler 8 is the heat-transfer surface-smoke pipe bundle 6 by arranging in the evaporimeter 5 directly, flue gas flows through in smoke pipe bundle 6, evaporation working medium flows through in the flue outside, obtains the heat that flue gas spreads out of and evaporates.Steam does work in heat supply steam turbine 10 and by generator 11-2 generating after the heating in the boiler 8, steam turbine 10 draw gas or the back pressure steam discharge is used for the heat supply of generator 1.Wherein, described steam turbine 10 draw gas or part that the blast pipe of back pressure steam discharge is arranged in the generator 1 is shapes such as snakelike or annular.
Gas power device 12 wherein can be gas turbine, internal combustion engine etc.
