The membrane module TANGENTIAL FILTRATION

摘要

The invention relates to devices intended for separation of liquid or gaseous media (such as for water purification, air separation and plasmapheresis blood at al.) Using the membrane elements of the folded type. Tangential filtration membrane module comprises a top cover with pipes for supplying and discharging filtered medium concentrate, the bottom cover with the filtrate discharge pipe, sidewalls and folded undulating membrane. Placed between the folds of the membrane and drainage potokoraspredelitelnye device. The module comprises potokoraspredelitelnyh n and n + 1, the drainage device. The first and last folds of the membrane sealed to the inner surfaces of the side walls. The ends of the membranes together with the end faces of the top, bottom and side walls of the covers placed in the sealant layer. The space between the upper cover, potokoraspredelitelnymi devices sidewalls and tops of the folds of the membrane between the inlet and outlet of the top cover sealed. The utility model can simplify manufacturing and improve the quality of the separation medium. 6 ZP f-ly, 5 Fig.
