Efficient module type heat exchanger

Abstract

The invention discloses an efficient module type heat exchanger which comprises a heat exchange body. One or more layers of heat exchange units are arranged in the heat exchange body. A plurality of layers of heat exchange pipes are horizontally and evenly arranged in each layer of heat exchange unit. The heat exchange pipes in each layer of heat exchange unit are in the consistent left-right direction and used for allowing high-temperature fluid to pass. The heat exchange units are sequentially communicated from top to bottom end to end, and an S-shaped high-temperature fluid circulating channel is formed from top to bottom. Shell sides of the heat exchange pipes in each layer of heat exchange unit are used for allowing low-temperature fluid to pass. The direction of the low-temperature fluid is perpendicular to that of the high-temperature fluid. In the same heat exchange unit, the low-temperature fluid flows from one end to the other end in the horizontal plane in an S-shaped manner. The side ends of the heat exchange units are sequentially communicated from top to bottom end to end, and an S-shaped low-temperature fluid circulating channel is formed from top to bottom. The efficient module type heat exchanger is high in heat efficiency and can be conveniently and flexibly combined.

Description

technical field [0001] The invention belongs to the technical field of heat exchangers, in particular to high-efficiency modular heat exchangers. Background technique [0002] As an advanced heat exchanger, the heat exchanger is mainly used in the transfer of heat exchange between liquid-liquid and vapor-liquid, so that heat can be transferred from a fluid with a higher temperature to a fluid with a lower temperature or a fluid with a lower temperature The fluid absorbs heat to increase its temperature, so as to achieve the purpose of rapid heat exchange, and is widely used in petrochemical, biopharmaceutical, food processing, shipbuilding and other fields. Examples include heat recovery, cooling, condensation and reboiling in amine systems. For example, heat recovery, heating and cooling in crude oil desalination and dehydration systems. Examples include condensation, heating and cooling, heat recovery and reboiling of olefins, aromatics, aldehydes, acids, ethers, esters,...

AI Technical Summary

Problems solved by technology

However, due to its large volume, low heat transfer efficiency and poor energy saving effect, it is not enough to meet the working conditions of various industries.

Taking the national standard GB151-1999 shell-and-tube heat exchanger as an example, the traditional shell-and-tube heat exchanger has a circular cylinder shape, and its structure consists of a head, a cylinder, a heat transfer tube, a baffle, and a saddle support. , connecting pipes, etc. and the heat transfer tube is a straight tube with a wall thickness of more than 2mm. And the heat transfer effect is low

Its structure is not easy to disassemble, resulting in difficult cleaning after fouling

In addition, the structure is not compact, the floor area is large, and the requirements for equipment and building layout are relatively high.
