A
flue gas treatment heat exchange tube and tube plate connection
system is characterized by comprising a
carbon plastic heat exchange tube, a connection sleeve type tube connector with one end with atube plate stop table and the other end with an outer thread and arranged between the
carbon plastic heat exchange tube and a tube plate, an isolation sleeve abutting against the end face of the tubeplate and installed on the connection sleeve type tube connector, an isolation sleeve sealing ring installed between the isolation sleeve and the connection sleeve type tube connector, a fastening nut with the
tail end with a mounting tool embedding inlet, abutting against the end face of the isolation sleeve and installed on the connection sleeve type connector, a nut type tube hoop, and a tubehoop sealing ring installed among the nut type tube hoop, the connection sleeve type tube connector and the
carbon plastic heat exchange tube, wherein the
tail end of the nut type tube hoop is provided with a mounting tool embedding inlet, an inner hole of the nut type tube hoop is in a step type, a large hole of the nut type tube hoop is provided with an inner thread, and the nut type tube hoop is installed at the
tail end of the connection sleeve type tube connector. The
system has the good mechanical performance and heat performance, and is convenient to
mount and dismount. The
flue gas treatment heat exchange tube and tube plate connection
system can be widely applied to
flue gas treatment systems, especially wet desulphurization white plume and
wastewater reduction cooperative treatment systems.
