Fluorocarbon resin production line

Description :

　　The outdated technology of heat exchange equipment is one of the important reasons for the low efficiency of energy utilization in China's chemical comprehensive production lines. The research and development of energy-saving heat exchange equipment is an important way for engineering energy conservation today. With the increasing shortage of conventional energy, the further improvement of energy consumption requirements for modern chemical integrated production lines, and the continuous expansion of industrial reproduction scale, how to ensure the utilization of energy under the premise of safety and production has received widespread attention from countries around the world, and various related research has also become a hot topic in academia and various engineering departments.

　　The comprehensive chemical production line is divided into three types of shell and tube heat exchangers according to the flow state of the shell side fluid: transverse flow, longitudinal flow, and spiral flow. Traditional baffle heat exchangers have lateral fluid flow in the shell side, which results in strong erosion of the heat transfer tubes. However, it is prone to flow and heat transfer dead zones, and the heat transfer area cannot be fully utilized. The flow resistance is high, and scaling is easy to occur. Moreover, when the flow velocity of the shell side fluid is high, induced vibration damage is prone to occur, which limits its application; The baffle rod heat exchanger achieves longitudinal flow of shell side fluid, exhibiting better heat transfer, low flow resistance, anti vibration and anti scaling performance. However, it also has the defects of insufficient compactness and poor heat transfer effect under low heat conditions; The spiral baffle heat exchanger realizes the spiral flow of shell side fluid, with a relatively smooth change in fluid velocity, and can effectively eliminate dead zones and backmixing phenomena.
