Flue gas treatment heat exchange tube and tube plate connection system

Abstract

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.

Description

Technical field [0001] The invention relates to a system for connecting a flue gas treatment heat exchange tube and a tube sheet, which can be widely used in a flue gas treatment system, especially in a wet desulfurization white plume and waste water reduction collaborative treatment system. Background technique [0002] In the existing heat exchanger, the material of the heat exchange tube is generally a metal material, and the tube sheet is also a metal material, and the two are connected by a metal-metal welding method. At present, it is difficult to realize non-metal-metal connection by welding, and cannot be welded and cemented, and only mechanical connection can be used. Summary of the invention [0003] The purpose of the present invention is to provide a flue gas treatment heat exchange tube and tube sheet connection system with excellent mechanical properties and thermal properties, and convenient installation and disassembly. [0004] In order to achieve the above objecti...
