1. Fixed shell and tube heat exchanger
The fixed shell and tube heat exchanger is a whole welded together by the tube sheet and the shell, and the pipe cannot be freely expanded or contracted. This type of heat exchanger is suitable for heat exchange under harsh conditions such as high pressure, high temperature and corrosion. The fixed shell and tube heat exchanger has the characteristics of simple structure, large heat exchange capacity and not easy to be blocked. It is often used in the processes of chemical, electric power, petroleum and other industries.
2. Floating shell and tube heat exchanger
The floating shell and tube heat exchanger uses special supports to allow the pipe to expand and contract freely within the verification range. This type of heat exchanger is suitable for occasions where the heat exchange temperature changes greatly, the flow rate is unstable or frequent cleaning and maintenance are required. The floating shell and tube heat exchanger has the characteristics of high heat exchange efficiency and good self-cleaning performance, and is often used in the processes of seawater desalination, chemical, food and other industries.
3. Spiral shell and tube heat exchanger
The spiral shell and tube heat exchanger is a process of winding a long spiral coil around the inside of the shell and guiding the fluid in it into the spiral coil to complete the heat exchange process. This type of heat exchanger is suitable for higher flow and temperature difference, and has the characteristics of high heat exchange efficiency, compact structure, and not easy to clog. It is often used in the processes of food, chemical, petrochemical and other industries.
4. Disc-type shell and tube heat exchanger
The disc-type shell and tube heat exchanger combines multiple concentric disc-shaped tube sheets together, and the fluid flows in the edge area of the concentric disc to complete the heat exchange process. This type of heat exchanger is suitable for occasions with unstable flow and easy clogging. It has the advantages of high heat exchange efficiency, compact structure, and easy maintenance. It is often used in chemical, pharmaceutical, food and other industries.
