FIELD: devices for fine purification of liquids and/or gasses. ^ SUBSTANCE: the invention is dealt with the devices for fine purification of liquids and/or gasses from suspensions, bacteria, viruses and chemical compounds dissolved in water and may be used both for individual consumers and for the industrial purposes. A filter for fine purification of liquids contains a body, a branch-pipe for a filtrate withdrawal, a filtering element made in the form of diaphragms made out off a microcapillary film creating a closed volume, in which a collector is formed. The body is made out of polymers and has a plane wavy surface. The filtering element is made out of a polymeric tracking diaphragm of = 10-50 microns thick and with open cylindrical through pores of a clear dimension from 0.01 microns up to 0.40 microns, or out of a polymeric tracking diaphragm of 20-30 microns thick with open conical through pores of a diameter equal to 0.2-0.3 microns and the number of pores about 5x108 per 1 cm2. The diaphragm is fixed by means of thermal soldering, the collector is formed by the surface of the body and diaphragms and filled in with a porous material with open pores of the size of 0.5-0.6 microns and with porosity of Pc Pd , and rigidity of the material of the filler of the collector Rcf Psp , where Pc is open porosity of the material of the collector, 10n/cm2; Pd - porosity of diaphragms of the filtering element, 10n/cm2; Rsp c - specific rigidity of the material of the collector, MPa; Prsp d f - specific pressure on the filter element diaphragm, MPa. The filter is a multi-unit one with a serial or in parallel connection of units. The technical result is increased reliability and the service life of the device at operation under excessive pressure of a liquid and-or a gas. ^ EFFECT: the invention allows to increase reliability and the service life of the device at operation under excessive pressure of a liquid and-or a gas. ^ 3 cl, 4 dwg |
