Tube type heat exchanger forming assembly method

Abstract

The invention relates to a tube type heat exchanger forming assembly method which uses tube type heat exchanger forming assembly equipment. The tube type heat exchanger forming assembly equipment comprises a base and an auxiliary device which is arranged on the upper surface of the base. The tube type heat exchanger forming assembly method can solve the current problems that as the shapes of a tube plate and a deflection baffle are different, but existing clamping equipment has the same clamping and fixing mode on the tube plate and the deflection baffle, it is difficult to completely clamp and fix the deflection baffle at the position where the tube plate can be clamped and fixed, the tube plate and the deflection baffle are completely fixed after one-time position calibration is performed for clamping and fixing, it is needed to open the clamping equipment again to adjust the positions of the tube plate and the deflection baffle for the problem of hole misalignment in subsequent assembly of heat exchange tubes, time and labor are wasted, and the heat exchanger production efficiency is seriously affected.

Description

technical field [0001] The invention relates to the field of heat exchanger manufacturing, in particular to a method for forming and assembling a tube-and-tube heat exchanger. Background technique [0002] Tube and tube heat exchanger is currently the most widely used heat exchanger in chemical industry and alcohol production. It is mainly composed of shell, tube sheet, heat exchange tube, head, baffle, etc. They are made of ordinary carbon steel, red copper, or stainless steel respectively. The structure of the shell and tube heat exchanger is relatively simple, compact and cheap. The outlet pipe at the other end of the head flows out, which is called the tube side; another fluid enters from the connecting pipe of the shell and flows out from the other connecting pipe on the shell, which is called the shell pass; [0003] At present, there are the following problems when assembling the formed tube sheets, heat exchange tubes and baffles of the tube-and-tube heat exchanger:...

AI Technical Summary

Problems solved by technology

[0004] 1. When the existing assembly of tube sheets, heat exchange tubes and baffles, due to the different shapes of the tube sheets and baffles, the existing clamping equipment for the tube sheets and baffles The clamping and fixing method is the same, resulting in the tube sheet can be clamped and fixed, but the baffle is difficult to be completely clamped and fixed, so that when the heat exchange tube is inserted into the hole on the tube sheet and the baffle When the baffle plate is unstable, the problem of instability of the baffle plate is likely to occur, which reduces the assembly efficiency of the tube sheet, heat exchange tubes and baffle plate;

[0005] 2. In the existing assembly of tube sheets, heat exchange tubes, and baffles, the clamping and fixing of the tube sheets and baffles is completely fixed after one-time position calibration. For subsequent assembly of heat exchange tubes, The problem of inaccurate hole alignment requires re-opening the clamping equipment to adjust the positions of the tube sheets and baffles, which is time-consuming and laborious, and seriously affects the production efficiency of the heat exchanger
