Shell and tube heat exchanger in air separation equipment, as an important heat exchange equipment, its structure principle is mainly based on the basic principle of heat conduction and convection, to achieve the exchange of heat between fluids. Shell and tube heat exchanger is mainly composed of shell, tube bundle, tube plate, folding plate (baffle), tube box several key components.
The working principle of shell and tube heat exchanger is to transfer heat from hot fluid to cold fluid by heat conduction and convection. Heat fluid flow: The heat source fluid flows through the tubes in the tube bundle, and because of the high temperature inside the tubes, heat is transferred outward along the tube walls. Heat transfer: The tube wall acts as a heat transfer surface and transfers heat to the shell process fluid in contact with it. Under the action of the folding plate, the shell process fluid constantly changes the flow direction, forming turbulent flow, which enhances the heat exchange with the tube wall. Cold fluid flow: The cooling fluid flows inside the shell and absorbs the heat transferred from the tube wall, thus lowering its temperature. Temperature regulation: Through the above process, the exchange of heat between the hot fluid and the cold fluid is realised, thus achieving the purpose of regulating the fluid temperature.
Shell and tube heat exchanger in air separation equipment realises efficient and stable heat exchange process through its unique structural design and working principle, which provides important support for industrial production.
