Abstract

A heat exchanger includes a first heat exchange tube module, a second heat exchange tube module and a corrugated compensator. The heat exchanger has the beneficial effects that one end of the first heat exchange tube module is connected with one end of the second heat exchange tube module through the corrugated compensator; due to the reasons of expansion with heat and contraction with cold and the like, the size of the corrugated compensator is changeable, and the corrugated compensator is used for adjusting the size change, and thus, service life of the heat exchange tube is prolonged; a port of a first heat exchange tube flanges and is connected with a first tube sheet through nuts, a port of a second heat exchange tube flanges and is connected with a second tube sheet through nuts, and consequently, the connection of the heat exchange tubes and the tube sheets is firm, and the heat exchange tubes are well sealed; and the first heat exchange tubes refer to the heat exchange tubes of glass fiber reinforced PTFE (polytetrafluoroethylene) tube sheets, and the second heat exchange tubes refer to the heat exchange tubes of glass fiber reinforced PTFE (polytetrafluoroethylene) tube sheets, and consequently the heat exchange tubes has fine performance of heat expansion and cold contraction and is hard to be damaged.

Description

technical field [0001] The invention relates to a heat exchanger, in particular to a heat exchanger in the field of chemical equipment. Background technique [0002] The heat exchanger has the advantages of high pressure resistance and high heat exchange efficiency. With the development of large-scale equipment, the thermal expansion of heat exchange tubes and tube sheets of heat exchangers at high temperatures also increases. The heat exchange tube is easy to bend, the weld seam cracks, and even the tube wall is torn. The connection between the heat exchange tube and the tube sheet is not strong enough. Contents of the invention [0003] In order to solve the above problems, the present invention aims at inventing a heat exchanger with strong connection and long service life of the heat exchanger. [0004] A heat exchanger includes a first heat exchange tube module, a second heat exchange tube module and a corrugated compensator, the first heat exchange tube module...
