Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, and more particularly to a shell-and-tube heat exchanger that is easy to maintain. Background Art

[0002] Shell and tube heat exchanger is a commonly used heat exchanger, usually composed of a shell, tube sheets, heat exchange tubes, baffles, etc. Due to its simple and compact structure and low cost, it is widely used in the chemical and pharmaceutical fields. Shell and tube heat exchanger can be used horizontally or vertically.

[0003] For example, a shell-and-tube heat exchanger with publication number CN219798034U, which is easy to fix, belongs to the field of heat exchanger technology. The heat exchanger includes a shell, heat exchange tubes, a first tube sheet, a second tube sheet, a first inlet pipe, and a first outlet pipe. The shell is outer-mounted with a connecting ring, which is provided with a support plate. The shell sidewall is provided with a connecting block, which is provided with a first threaded hole. The connecting ring is detachably connected to the connecting block via a first bolt. The utility model can connect the heat exchanger as a whole to an external bracket, facilitating positioning during installation of the heat exchanger, reducing the difficulty of heat exchanger installation, and improving the efficiency of heat exchanger installation. The connecting ring is detachably connected to the connecting block via a first bolt, facilitating rotation of the connecting ring, thereby facilitating adjustment of the direction of the support plate. The connecting block is provided with multiple first threaded holes, facilitating adjustment of the left and right position of the connecting ring, and the support plate has a wide range of use areas.

[0004] However, based on the working principle proposed in the above patent, the applicant believes that although the above device can facilitate the adjustment of the direction of the support plate to a certain extent, in actual use, the tubes are prone to internal blockage after being used for a long time. The above device has weak maintenance capabilities for the internal tubes and is difficult to disassemble and install, which causes certain inconveniences when used.

[0005] Therefore, in order to solve the above problems, a shell and tube heat exchanger which is easy to maintain is proposed. Utility Model Content
