Description

Technical Field

[0001] The utility model relates to the technical field of tubular heat exchangers, in particular to an energy-saving tubular heat exchanger. Background Art

[0002] With the development of society and the continuous progress of mankind, coupled with the influence of the social environment, the use of tubular heat exchangers has become more and more widespread. A tubular heat exchanger is a heat exchange device composed of a tube and a shell. Its working principle is based on heat conduction and fluid flow. During the operation of the tubular heat exchanger, there are two main fluid flow paths: a cold fluid path and a hot fluid path. The cold fluid enters the tubular heat exchanger from one side, passes through the tube wall, and is separated from the flow path of the hot fluid in the tube by a certain distance. The heat conduction within this distance causes heat energy to be transferred from the hot fluid to the cold fluid, causing the temperature of the hot fluid to decrease while the temperature of the cold fluid increases, completing the heat exchange operation.

[0003] When the existing tubular heat exchanger is in use, the whole is mainly composed of a shell, a tube bundle, a tube sheet and a head. The shell is mostly circular, and a parallel tube bundle is installed inside. The two ends of the tube bundle are fixed to the tube sheet. The overall energy-saving effect is poor when in use. When performing heat exchange operations, it takes a long time and the heat exchange effect is not good. At the same time, it is inconvenient to disassemble the tube sheet during use. During the transmission of hot and cold flows, some impurity particles will adhere to the tube sheet, which will affect the heat exchange efficiency of the heat exchanger and need to be disassembled and cleaned. If the tube sheet is not disassembled and cleaned in time, it will be damaged due to excessive impurities, which greatly reduces the service life of the tube sheet. Utility Model Content
