This partial fume directly discharges, and the present invention passes through blast pipe by being reused to the residual temperature energy of this partial fume
The setting of pipe is changed with air inlet pendulum so that flue gas in blast pipe is before discharge and enters the surrounding air that air inlet pendulum is changed in pipe and enters
Row heat exchange, so as on the one hand lift the air themperature of surrounding air, reduce the air humidity of surrounding air, so as to being lifted
The air themperature of the generating intracavitary of gas electricity generator, reduce gas electricity generator generating intracavitary air humidity, add
The oxygen content of air, so as to which burning situation of the gas electricity generator for natural gas be greatly optimized, improve the utilization of natural gas
Rate, saved substantial amounts of natural gas, another aspect flue gas after heat exchange again, temperature can be reduced to 50 DEG C~60 DEG C it
Between, so that last fume emission possesses the more preferable feature of environmental protection.
Natural gas enters the generating intracavitary of gas electricity generator, is the combustion that generating intracavitary is lifted by the natural gas that burns first
Temperature is burnt, generated electricity by the natural gas that burns again, general 1 cube of air, which often raises 1 degree, to be needed to consume 260 card energy
Amount, the present invention change the ingenious structure design of pipe by blast pipe and air inlet pendulum, it is possible to increase the ring entered in gas electricity generator
Border temperature, so as to reduce the dosage of the natural gas to be heated up for the generating chamber to gas electricity generator, so as to improve day
The utilization rate of right gas.
Further, it is provided with return pipe between the heat exchanger and user.
Further, the blast pipe and air inlet pendulum change the junction of pipe and are provided with seal washer, so that blast pipe
The junction for changing pipe with air inlet pendulum possesses high sealing performance, it is therefore prevented that the air inlet surrounding air that changes in pipe of pendulum is from blast pipe and air inlet
The junction that pendulum changes pipe is largely lost in.
Further, the blast pipe is changed outside the mouth of pipe of pipe towards air inlet pendulum and extended obliquely out, so that surrounding air
The emission direction of airintake direction and flue gas is interleaved next, will not influence each other.
Further, the sealing gasket is FFKM seal washer, and FFKM possesses good resistance to elevated temperatures, made
Obtaining the performance of glue seal washer will not be influenceed by blast pipe high temperature.
Beneficial effect：The present invention compared with prior art, possesses following advantage：
1st, using flue gas and enter air inlet pendulum and change surrounding air in pipe and carry out heat exchange, so as to improve surrounding air
Temperature, ambient air humidity is reduced, after surrounding air enters gas electricity generator generating intracavitary, reduce gas electricity generator hair
The air humidity of electric intracavitary, the air themperature for improving generating intracavitary, the oxygen content for adding air, so as to which combustion be greatly optimized
Gas generator improves the utilization rate of natural gas, has saved substantial amounts of natural gas, distributed energy for the burning situation of natural gas
The operating cost of source system is greatly reduced；
2nd, after heat exchange again, temperature can be reduced between 50 DEG C~60 DEG C flue gas, so that last cigarette
Gas discharge possesses the more preferable feature of environmental protection；
3rd, because the utilization rate of natural gas has obtained significantly being lifted, substantial amounts of natural gas, therefore the row of flue gas have been saved
It high-volume there has also been and be greatly reduced, so as to reduce the carbon emission in outwardly environment, improve cold, heat and electricity triple supply distribution energy
The environmental-protecting performance of source system.
