Description

Technical Field

[0001] The utility model relates to the technical field of tubular heat exchangers, in particular to a high-temperature tubular heat exchanger. Background Art

[0002] The high-temperature tubular heat exchanger is a partition-type heat exchanger that uses the wall of the tube bundle enclosed in the shell as the heat transfer surface. This type of heat exchanger has a simple structure, low cost, wide flow cross-section, and is easy to clean scale, but has a low heat transfer coefficient and occupies a large area. It can be made of various structural materials (mainly metal materials) and can be used under high temperature and high pressure. It is the most widely used type.

[0003] The existing high-temperature tube heat exchanger uses a simple multiple bolt connection to connect the shell and the head. The speed of disassembly and installation of the head connecting the shell of the high-temperature tube heat exchanger is slow, and the weight of the heat exchanger is heavy, which makes it inconvenient to move the heat exchanger during installation. Therefore, we propose a high-temperature tube heat exchanger to solve this problem. Utility Model Content
