Preparation method of flue gas bipolar heat exchanger for radiant tube burner

Abstract

The invention discloses a preparation method of a flue gas bipolar heat exchanger for a radiant tube burner, which comprises the following steps: respectively and independently assembling and welding three assemblies, namely an internal finned tube assembly, a flue gas cavity assembly and an air inlet connecting tube assembly, respectively carrying out airtight detection after welding, and then, firstly sleeving the flue gas cavity assembly into the internal finned tube assembly; and then the smoke cavity assembly is connected with the connecting flange, on the outer side of the connecting flange, the flange of the air inlet connecting pipe assembly is connected with the outer side of the connecting flange, and assembling can be completed. The manufacturing process is simple and efficient, the working procedures do not restrain each other, production is flexible, and the situation that the whole working procedure is affected due to stagnation of one working procedure is avoided; the delivery state of finished products is flexible and variable, and the finished products can be transported to an installation site after being assembled in a manufacturing factory and can also be packaged and transported in a classified mode according to assemblies and flexibly assembled on the installation site; the technical key points are clear and controllable, and the production efficiency and the product quality are greatly improved; and the productivity efficiency in the process assembling and welding process is high, and 100 machines can be achieved by 5 persons per 16 shifts.

Description

technical field [0001] The invention relates to a preparation method of a flue gas bipolar heat exchanger for a radiant tube burner, and belongs to the technical field of heat exchangers. Background technique [0002] Heat exchanger is a kind of general equipment widely used in chemical industry, oil refining, metallurgy, power, light industry, atomic energy, pharmacy, machinery and many other industrial fields. According to different industrial furnace equipment, a variety of radiant tube burners are designed. Gas bipolar waste heat exchanger. [0003] In recent years, my country and other countries in the world have continuously improved the requirements for product quality, waste heat recovery and control technology, especially environmental protection requirements such as pollutant discharge, and radiant tube heating technology has also been continuously promoted and improved; The heat exchanger manufacturing process to improve production efficiency and reduce production...

AI Technical Summary

Problems solved by technology

[0006] 1. However, there is room for research and development in the production process, and the productivity and delivery time of shift personnel still need to be improved;

[0007] 2. The delivery status of the finished product is not flexible enough, and it cannot be packaged and transported according to the assembly, and it can be assembled flexibly at the installation site;

[0008] 3. The selection of welding position is not flexible enough to meet the overall requirements of small and controllable welding deformation variables, high production efficiency and product quality
