Filtration apparatus

Abstract

Abstract PURPOSE:To obtain an apparatus having excellent removability of fine particles, filtration rate, chemical and heat resistances by using a porous membrane of polytetrafluoroethylene and a support of fluoroplastics having a specific shape, and making all parts of fluoroplastics. CONSTITUTION:A tubular filter body 8 is constituted by covering the outside of a tubular support of fluoroplastics with a tubular filtration membrane of polytetrafluoroethylene (PTFE) one end of which is closed, or inserting the filtration membrane into said support. And the tubular support 8 is arranged in a vessel of fluoroplastics which is constituted basically of outer vessels 5,6 and a supporting plate 7. A sheet-shaped porous PTFE made into a tubular form one end of which is closed is suitably used as the PTFE tubular filtration membrane. A porous molded tube obtained by sintering granular PTFE is suitable for the tubular support of fluoroplastics, since the molded tube is characteristically low in permeation resistance and difficult to deform.
