Anticorrosive gas gas heater of pipe formula fluoroplastics is arranged to U type

The utility model relates to an anticorrosive gas gas heater of pipe formula fluoroplastics is arranged to U type, the U type arranges that the anticorrosive heat exchanger of pipe formula fluoroplastics includes that anticorrosive gas gas heater shell, anticorrosive U type arrange fluoroplastics pipe group, single tube restraining mechanism, fluoroplastics heat exchanger erection bracing frame, flue gas access & exit, heat transferring medium access & exit and seal part, the U type is prepared into to the inside pipe of the anticorrosive gas gas heater of fluoroplastics, and space utilization is high, and heat transfer area increases by 10%~20%, has improved heat exchange efficiency, can effectively reduce the thermal stress simultaneously, fluoroplastics pipe group passes through single tube restraining mechanism to be fixed inside heat exchanger shell, prevents that the flue gas flow from producing the shake to fluorine plastic monotube to improve the reliability of heat exchanger. 本实用新型是种U型布置圆管式氟塑料防腐烟气换热器
