MEMBRANE DEVICE FOR WATER TREATMENT PLANT Russian patent published in 2012 - IPC B01D35/12 B82B1/00 

FIELD: process engineering.

SUBSTANCE: invention relates to membrane fluid treatment device to be used in power engineering, petrochemical industry, etc. It comprises casing 5, filtration elements, tube plate, hydraulic accumulator, feed branch pipe 11, lower and lateral discharge branch pipes 10 and 1, valves 8, 6 and 7, and insert. Filtration elements are mounted inside casing 5 parallel with its lengthwise axis on said tube plate with the help of unions. Cavities of said unions are communicated with inner spaces of hydraulic accumulators and those of filtration elements. Lower discharge branch pipe 10 is arranged at casing bottom. Said hydraulic accumulator is made up of container arranged above said casing 5. Lateral discharge branch pipes 1 is communicated with hydraulic accumulator chamber bottom. Tube plate is attached to hydraulic accumulator from below. Filtration elements consist of cylindrical porous substrate and nanostructured membrane arranged on outer lateral surface of the latter. Filtrations elements are confined by bottoms 4 and unions 15 at top and bottom sections. Feed branch pipes 11 is arranged at casing bottom lateral section.

EFFECT: increased depth of fluid cleaning, longer life of membrane module.
