The heat exchanger which takes the small-diameter polytetrafluoroethylene hose as the heat transfer component is also called as a flexible pipe heat exchanger. The tetrafluoro heat exchanger is mainly used for heat exchange of various strong corrosive media, such as cooling or heating of sulfuric acid, chloride solution with strong corrosivity, acetic acid and caustic media.
The structure of the tetrafluoro heat exchanger includes a shell-and-tube heat exchanger and an immersion heat exchanger. Their main part is a tube bundle consisting of a number of small-diameter thin-walled polytetrafluoroethylene heat transfer hoses. The common pipe specifications are diversified, and the outer diameter multiplied by the wall thickness is respectively 3-25 mm multiplied by 0.3-0.1 mm. The tube bundle comprises 60-5000 tubes, and the two ends are separated from each other by a polytetrafluoroethylene tape. The tube bundle is inserted in a ring and welded into an integral honeycomb tube sheet. The other parts of the tetrafluoro heat exchanger are slightly the same as those of the common shell-and-tube heat exchanger and submerged heat exchanger which use metal tubes as heat transfer components.
The chemical properties of polytetrafluoroethylene are extremely stable and the corrosion resistance is particularly good. The polytetrafluoroethylene tube wall surface is smooth and moderately flexible, and micro-vibration during use provides a molding benefit. The heat transfer area in unit volume of the equipment is more than 4 times of that of a shell-and-tube heat exchanger with a metal tube, the heat exchange efficiency of the existing tetrafluoro heat exchanger is not high enough, and in the process of heat exchange work, abnormal sound or noise can be caused by the occurrence of torrent inside the tetrafluoro heat exchanger.
