Device for utilizing electric heating tantalum expansion-prevention pin for sintering fluorine plastic pipe heat exchanger pipe plate

Abstract

The invention discloses a device for utilizing an electric heating tantalum expansion-prevention pin for sintering a fluorine plastic pipe heat exchanger pipe plate. The device comprises a circuit board device, cables, metal pressing plates, locking devices, movable chopping boards, fluorine plastic pipe bundles, electric heating tantalum pipes and the fluorine plastic pipe plate. The pair of metal pressing plates are connected with the pair of movable chopping boards below the metal pressing plates through the locking devices respectively, and the two ends of the fluorine plastic pipe plate are fixedly arranged between the metal pressing plates and the movable chopping boards; the fluorine plastic pipe plate is locked by the locking devices connected to the metal pressing plates and the movable chopping boards; the electric heating tantalum pipes are inserted into the fluorine plastic pipe bundles, and the fluorine plastic pipe bundles are inserted into fixed holes in the fluorine plastic pipe plate to be fixed; and each electric heating tantalum pipe comprises a cable, a tantalum cover, an expansion-prevention tantalum pipe, magnesium powder and an electric heating wire. The technical aims that tantalum pipe heat sintering and the expansion-prevention pin can be multiply utilized, a traditional PTFE heat exchanger pipe plate sintering complex technology process is simplified, and the sintering efficiency is improved are achieved.

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.
