Problems solved by technology

The disadvantage is that the fixing part of the heat exchange tube and the tube sheet is easy to loosen and produce a small gap, which will leak the liquid in the heat exchanger cylinder.
Its disadvantage is that it is affected by stress, and it is easy to crack at the weld, causing the liquid in the heat exchanger cylinder to leak

Embodiment Construction

[0021] like figure 1 , figure 2 As shown in the figure, a method for heat exchange tubes of a tube-plate heat exchanger is to first open two or three grooves 4 in the inner wall of the hole 2 of the tube plate 1; then insert the heat exchange tube 3 into the hole 2 of the tube plate 1. Then, insert a tube expander to expand the heat exchange tube 3 at the hole 2, and then fasten it to the tube sheet 1 and insert the heat exchange tube 3 at the corresponding position into the groove 4.

[0022] The number of grooves 4 is set according to the thickness of the tube sheet. The thicker the tube sheet 1 is, the more grooves 4 are opened. The groove 4 is processed into a cross-sectional shape such as image 3 The one or more circumferential grooves of the "C" shape, or the "V" shape or the "" shape shown are the preferred technical solutions of the present invention. Of course, it can also be processed into one or more grooves with other regular or irregular cross-sectional shap...

Abstract

The invention relates to a method for fastening a heat exchange tube of a tube sheet heat exchanger. The method is characterized by comprising the following steps that (a) one or more grooves are formed in the hole inner wall of a tube sheet; (b) the heat exchange tube is inserted into a hole; and (c) a tube expander is inserted into the heat exchange tube, and the heat exchange tube located in the hole position of the tube sheet is expanded through the tube expander and then is fastened with the tube sheet to be embedded into the corresponding grooves. The sealing property of a combination position of the heat exchange tube and the tube sheet is effectively guaranteed, and using is more lasting and safer.

Description

technical field [0001] The invention relates to a heat exchanger in the printing and dyeing industry, in particular to a method for fastening heat exchange tubes of a tube-plate heat exchanger. Background technique [0002] Tube plate heat exchanger is a commonly used heat exchange equipment in the printing and dyeing industry. Including a cylinder, the upper and lower ends of the cylinder shell are respectively provided with a heat source inlet and a heat source outlet, which are respectively placed at the two ends of the cylinder and have a number of holes. The holes in the tube plate, the heated liquid flows in the heat exchange tube. Its working principle is: after the heat source enters the cylinder from the heat source inlet, it fills the cylinder, and finally exits from the heat source outlet. During this process, the heated liquid in the heat exchange tube is directly heated by the heat source. [0003] At present, most of the methods used to fasten the heat excha...
