STREAMLINE MEMBRANE FILTER Russian patent published in 2004 - IPC

FIELD: fine purification and a mechanical decontamination of drinking water; concentrating medicinal preparations. SUBSTANCE: the invention presents a streamline membrane filter, that may be used for fine purification and a mechanical decontamination of drinking water; concentrating medicinal preparations, etc. Technical substance: the streamline membrane filter, contains a body with installed inside demountable filtering elements in the form of the porous tubes, a lid and the bottom with branch-pipes for the processed medium feeding in and taking out and a branch-pipe for the purified medium taking out. At that the filtering elements are mounted concentrically and sizes of pores of each of them are smaller than sizes of pores of the previous one in a radial direction from the axis of the filter, and the lid is supplied with a bush and a pipe stub located in the branch-pipe of the being processed medium taking out, in which one side ends of the filtering elements are hermetically fixed. The length of the bush is in ratio of no less than 1/10 of length of the body; at that on the bottom of the body there is a hermetically fixed T-branch with a pipe stub for the purified medium taking out and a pipe stub mounted in a branch-pipe for the processed medium feeding, in which the other ends of the filtering elements are hermetically fixed. EFFECT: the invention ensures increase of efficiency of streamline membrane filter operation due to its compactness, that is improvement of its mass-dimensions parameters. 12 cl, 3 dwg
