FILTRATION MODULE Russian patent published in 2006 - IPC B01D63/06 

FIELD: petroleum industry; other branches of industry; municipal services; separation of the heterogeneous mediums.

SUBSTANCE: the invention is pertaining to the field of separation of the heterogeneous mediums and may be used for purification of the liquids, as well as in the processes of separation of substances. The filtration module contains the mounted in the body membrane filter, which has been made out of the complete set of the rigid semi-permeable ceramic components made in the form of pipes or the channel containing rods hermetically fixed in the holes of the flanges. The membrane filter flanges are made out of the tightly sintered pyroceramics. Fixation of the ceramic components in the holes of the flanges is made using the glass-ceramic sealant with formation of the monolithic structure. Pyroceramics, the glass-ceramic sealant and the material of the ceramic components have the equal values of the thermal linear expansion coefficient. It allows to improve reliability in conditions of the prolonged multiple operation and to ensure the sterile filtering keeping the leakproofness of fixation of the filtering components in the holes of the flangesunder the aggressive conditions and at the high temperatures of the regeneration.

EFFECT: the invention ensures improved reliability of the filtration module prolonged multiple operation at the sterile filtering with keeping the leakproofness of fixation of the filtering components in the holes of the flanges in aggressive conditions and at high temperatures of regeneration.
