Detachable finned tube heat exchanger

Abstract

The invention discloses a detachable finned tube heat exchanger, and belongs to the field of heat exchangers. The tail structure of the shell can adopt a blind flange, an end socket or a flat cover, the blind flange is connected with the shell through bolts to realize fixed sealing, and the end socket and the flat cover are welded with the shell. The core assembly is supported and placed on a slide way in the shell through the idler wheels installed on the lower sealing plate, the bottom of the movable pipe plate can be lengthened till the inner surface of the shell so that the core assembly can be supported, and the detachable function of the core assembly is achieved. And elastic sealing strips are mounted on the upper and lower sealing plates of the core group and the return water cover, and cling to the surfaces of the L-shaped wind shields and the slideways in the shell or the inner surface of the shell. And the fins are combined type enhanced heat transfer fins with slots, grooves or longitudinal vortex generators, so that the heat exchange performance of the heat exchanger is further improved. The detachable finned tube heat exchanger and the sealing mode thereof have the advantages of being compact in structure, large in heat exchange area, high in heat transfer efficiency, convenient to disassemble, replace and wash and convenient for large-scale production.

Description

technical field [0001] The invention belongs to the field of heat exchangers, and in particular relates to a detachable finned tube heat exchanger, which can be used for waste heat recovery, and is especially suitable for compressed air waste heat recovery, and belongs to the technical field of heat exchange equipment. Background technique [0002] As a research hotspot in recent years, low-grade waste heat recovery has become more and more important under the background of "carbon peaking and carbon neutralization". In the industrial field, my country has achieved remarkable results in the recovery and utilization of high- and medium-temperature waste heat, but compared with developed countries, there is still a certain gap in the recovery and utilization of low-grade waste heat in my country. Gas waste heat resources mainly come from flue gas, compressed air, etc. [0003] The difficulty of low-grade waste heat recovery is that the temperature difference is small. For com...
