MEMBRANE APPARATUS Russian patent published in 1999 - IPC

FIELD: tubular membrane apparatuses for treatment of liquids, in particular, treatment of sewage of industrial enterprises, natural waters in water supply systems, treatment of lubricant-coolants in the process of recovery of waste oils and detergent solutions and for concentration of solutions of ferments, clarification of juices, etc. SUBSTANCE: the membrane apparatus has a body with branch-pipes for delivery of source liquid, discharge of treated liquid and concentrate and tube plates with tubular membrane members attached to them. One end of the tubular membrane members is closed by plugs of sealant and clamped by a bearing head with blind holes for each membrane member. The other end of the membrane members is sealed by means of two tube plates, with a layer of sealant filled up between them, and clamped by a perforated bearing disk with a diameter of holes equal to the inside diameter or smaller than the inside diameter of the tubular membrane members through the layer of sealant. EFFECT: reduced specific quantity of metal per structure and labour input in manufacture, enhanced range of temperature conditions and provision of impulse high-rate washing by return flow of treated liquid during the whole service life without replacement of separate tubular members. 1 dwg
