Description
technical field [0001] The invention relates to a heat exchanger device. Background technique [0002] Fluoroplastic heat exchanger is an important type of heat exchanger equipment, its corrosion resistance is superior to many alloys, non-metals and even precious metals. Its development, development and practical application have gone through more than 20 years of evolution, and now it has There are many fluoroplastic products with different structures, different uses and properties. Due to the poor fusion performance between PTFE, the biggest technical problem of this type of heat exchanger is the sealing process between the fluoroplastic tube bundle and the tube sheet. The fluoroplastic heat exchanger produced by the traditional process generally has a sealing of 3%. The blocking rate, but if the fluoroplastic tube heat exchanger is used in the heat exchange of highly corrosive chemical liquids, the leakage of the heat exchange medium will have serious consequences.
