CARTRIDGE OF THE FILTERS-SEPARATORS FOR PURIFICATION OF FUELS Russian patent published in 2004 - IPC

FIELD: petroleum refining industry. SUBSTANCE: the invention presents a cartridge of filters-separator for purification of fuels, that may be used in petroleum refining industry, aircraft and automobile, etc. industries for hydrocarbonaceous fuels purification from free water and mechanical impurities. The cartridge of the filters -separators for purification of fuels contains located along the flow of the being purified fuels the first and second filtering coagulating layers, a layer for integration of free water made in the form of a cotton tube and a water-repellent layer. The filtering layer is made of two layers of paper with reduction of the sizes of pores in direction of the fuel downstream. The first coagulating layer has the form of a mat made out of glass-fibers with a fiber diameter of 1.5-2 microns and is pressed out by a glass-fibers grid with a mesh width of 1.6x2.5 mm. The second coagulating layer is made out of the needle punched felt "Rudfil" with the surface density of 270-285 g / m sq. The cotton tube is stretched on the cylindrical surface of the cartridge with the effort ensuring an increase of the size of its cells up to 1.2-1.5 against the initial size. Technical result is improvement of quality of purification of the hydrocarbonaceous fuels from mechanical impurities and free water with simultaneous increase of speed of the fuel pumping over. EFFECT: the invention allows to improve quality of the hydrocarbonaceous fuels purification from mechanical impurities and free water with simultaneous increase of speed of the fuel pumping over. 2 tbl, 1 dwg
