Abstract

The invention discloses an inner diversion type self-tightening hanging part of a heat exchange tube, mainly comprising a hollow shaft, a connecting rod, a support table and an extension end, wherein the hollow shaft, the support table and the extension end are respectively a concentric cylindrical body with an inner hole, the diameter of the inner hole of the hollow shaft is a little bigger than the diameter of a rotary shaft, the hollow shaft and the support table are fixedly connected through the connecting rod, the outer diameter of the extension end is a little bigger than the inner diameter of the heat exchange tube, the diameter of the support table is equal to the diameter of the extension end, the outer diameter of the support table is bigger than the outer diameter of the heat exchange tube and smaller than the center distance of two nearest heat exchange tubes in a heat exchanger, the support table is fixedly connected with the extension end, a section of notch is respectively arranged at the middle position of two adjacent connecting rods on the support table and the extension end, the notches of the support table and the extension end are beneficial to the stretching of the extension end in the radial direction and are beneficial to the installation of the hanging part and the tightening in the heat exchange tube, the notch of the extension end is beneficial to reducing the resistance to a fluid and saving the cost, and a diversion surface of the support table and a spiral groove structure have certain effects of heat transfer enhancement and scale control and removal.

Description

technical field

[0001] The invention relates to a support element for an interpolation element used in heat exchange tubes for strengthening heat transfer and antifouling and decontamination in shell-and-tube heat exchangers, heat exchange reactors and other equipment. Background technique

[0002] With the continuous progress of society in the 21st century, energy saving and emission reduction in today's society is a key technology that the whole world attaches great importance to, especially in many fields such as petroleum, chemical industry, thermal power, nuclear power, metallurgy, light industry, aviation devices and ship vehicles. It has to be applied to many heat exchangers, the most widely used is the shell and tube heat exchanger, but in these heat exchange tubes, there are generally layered dirt on the inner wall, which leads to an increase in the resistance of the fluid in the pipeline, and in severe cases, it will be blocked. At the same time, the heat transfer ...
