Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, in particular to a polytetrafluoroethylene heat exchanger with good sealing performance. Background Art

[0002] Heat exchangers are indispensable equipment for heat exchange and transfer in the chemical production process. However, some corrosive and highly oxidizing materials are often used in heat exchange. Therefore, the materials used to manufacture heat exchangers are required to have strong corrosion resistance. Commonly used corrosion-resistant materials include non-metallic materials such as graphite, ceramics, glass, polytetrafluoroethylene, and metal materials such as stainless steel, titanium, tantalum, and zirconium. However, heat exchangers made of non-metallic materials such as graphite, ceramics, and glass have the disadvantages of being fragile, bulky, and having poor thermal conductivity. Heat exchangers made of metal materials such as titanium, tantalum, and zirconium are too expensive due to the high material cost. Stainless steel has poor corrosion resistance to some corrosive media, and its use poses a safety hazard. Polytetrafluoroethylene is a synthetic polymer material with excellent chemical stability, strong corrosion resistance, and excellent surface non-stickiness. Therefore, it is widely used in highly corrosive industrial environments. Heat exchangers made of polytetrafluoroethylene are widely used in highly corrosive chemical industries.

[0003] However, during the use of existing heat exchangers, ordinary sealing gaskets or sealing strips are used for sealing connections, and the connections are installed with bolts, which makes disassembly more troublesome, and the bottom saddle lacks vibration damping. Therefore, based on the above problems, a polytetrafluoroethylene heat exchanger with good sealing performance is introduced. Utility Model Content
