Background technology
At present, be the cogeneration system of power with the gas internal-combustion engine, the mechanical energy that gas internal-combustion engine is exported that adopt are connected with generator more, by generator powered.The flue gas of gas internal-combustion engine is directly imported waste heat boiler, is used for heating the waste heat boiler feedwater.The exhaust gas temperature of general waste heat boiler is higher, about 150 ℃.The general direct discharge of used heat in the gas internal-combustion engine aerial cooler or be directly used in the local heat supply that needs water at low temperature in addition, but because coolant-temperature gage is lower, range of application is very limited.This shows and adopt the shortcoming of this traditional cogeneration system to be, energy is not fully utilized, and not only energy loses in vain, but also has caused certain environmental pollution.
Technology contents
At problems of the prior art, the purpose of this invention is to provide a kind of is the heat-pump-type cogeneration system of power with the internal combustion engine, and it can make the energy of the heating system of internal combustion engine be fully utilized, and reduces the pollution to environment.
In order to reach above-mentioned goal of the invention, technical scheme of the present invention realizes as follows:
A kind of is the heat-pump-type cogeneration system of power with the internal combustion engine, and it is made up of gas internal-combustion engine, absorption heat pump unit, condensing heat exchanger and generator.The mechanical energy of described gas internal-combustion engine output is connected with generator.Its design feature is: the generator of the flue gas of described gas internal-combustion engine by absorption heat pump unit be connected with set condensing heat exchanger smoke inlet and by condensing heat exchanger from the exhanst gas outlet exhaust.The water route outlet of gas internal-combustion engine aerial cooler is all joined with the evaporimeter water route import of absorption heat pump unit with the water route outlet of condensing heat exchanger.The evaporator water way outlet of absorption heat pump unit joins with the water route import of gas internal-combustion engine aerial cooler and the water route import of condensing heat exchanger respectively.The condenser of absorption heat pump unit and absorber and heating backwater polyphone/access heating water supply loop in parallel.
The cogeneration system that the above-mentioned type of attachment that the present invention adopts is formed, can effectively utilize the high temperature heat source of the higher smoke evacuation of temperature as the absorption heat pump unit generator, exhaust gas temperature is reduced greatly, realized the recovery of flue gas heat, improved the thermal efficiency of system.Utilize the low-temperature heat source of the heat of gas internal-combustion engine aerial cooler and condensing heat exchanger in addition, realized the cascade utilization of the energy as the absorption heat pump unit evaporimeter.Pollution to environment simultaneously reduces to minimum degree.
The present invention is described further below in conjunction with accompanying drawing and concrete embodiment.
Description of drawings
Accompanying drawing is an operation principle structure connection layout of the present invention.
The specific embodiment
Referring to accompanying drawing, heat-pump-type cogeneration system of the present invention, it is by gas internal-combustion engine 3, absorption heat pump unit 4, condensing heat exchanger 1 and generator 2 are formed.The mechanical energy of gas internal-combustion engine 3 outputs is connected with generator 2, and by generator 2 generatings, this is same as the prior art.Different is, about 450 ℃ flue gas that gas internal-combustion engine 3 is discharged enters the generator of absorption heat pump unit 4, and the generator by absorption heat pump unit 4 enters condensing heat exchanger 1, by exhaust again behind the condensing heat exchanger 1, and about 30 ℃ of delivery temperature at this moment.The water route outlet of gas internal-combustion engine 3 aerial coolers is all joined with the evaporimeter water route import of absorption heat pump unit 4 with the water route outlet of condensing heat exchanger 1.The evaporator water way outlet of absorption heat pump unit 4 joins with the water route import of gas internal-combustion engine 3 aerial coolers and the water route import of condensing heat exchanger 1 respectively.The condenser of absorption heat pump unit 4 and absorber are connected in series or are parallel to the heating water supply loop with the heating backwater.
In the use, natural gas is work by combustion in gas internal-combustion engine 3, and the generator and the condensing heat exchanger 1 of absorption heat pump unit 4 passed through in gas internal-combustion engine 3 smoke evacuations successively.The aerial cooler heat of condensing heat exchanger 1 and gas internal-combustion engine 3 is jointly as the low-temperature heat source of absorption heat pump unit 4 evaporimeters.Absorption heat pump unit 4 generator high temperature heat sources are provided by the high temperature smoke evacuation of gas internal-combustion engine.
