Background technique

A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid, also known as a heat exchanger. Heat exchangers play an important role in chemical, petroleum, power, food and many other industrial productions. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators and reboilers, etc., and are widely used . For example, the PTFE heat exchanger for low temperature in power plants is a new device for waste heat recovery in power plants to reduce the exhaust gas temperature. The use of fluoroplastic heat exchangers can prevent acid corrosion and reduce the flue gas temperature to less than 100 degrees. Zhengzhou University of Technology successfully developed the PTFE tube-sheet limited-expansion pressure-heating welding process, which solved the key technology of connecting fluoroplastic tubes and tube sheets. Subsequently, various types of domestic heat exchangers were put into practical production and application and obtained good effect.

The existing tubular heat exchanger and the base are generally connected by flange connection, and the installation steps are relatively cumbersome, and the fixed flange holes need to use screws of a fixed size.
