The junction for changing pipe with air inlet pendulum has high sealing performance, it is therefore prevented that air inlet pendulum changes surrounding air in pipe from exhaust pipe and air inlet
The junction that pendulum changes pipe is largely lost in.
Further, the exhaust pipe is changed outside the nozzle of pipe towards air inlet pendulum and is obliquely extended, so that surrounding air
The emission direction of airintake direction and flue gas is interleaved next, will not influence each other.
Further, the gasket is perfluoroelastomer seal washer, and perfluoroelastomer has good high temperature resistance, makes
Obtaining the performance of glue seal washer will not be influenced by exhaust pipe high temperature.
Advantageous effect：The utility model compared with prior art, has following advantage：
1st, it using flue gas and enters air inlet pendulum and changes surrounding air in pipe and carry out heat exchange, so as to improve surrounding air
Temperature reduces ambient air humidity, after surrounding air enters gas electricity generator power generation intracavitary, reduces gas electricity generator hair
The air humidity of electric intracavitary, the air themperature for improving power generation intracavitary, the oxygen content for increasing air, so as to which combustion be greatly optimized
Gas generator improves the utilization rate of natural gas, has saved a large amount 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 has the better feature of environmental protection；
3rd, since the utilization rate of natural gas has obtained significantly being promoted, a large amount of natural gas, therefore the row of flue gas have been saved
