FIELD: process engineering. ^ SUBSTANCE: invention is intended for removing mechanical impurities and water from hydrocarbon fluids. Filtration element comprises rigid permeable cylindrical carcass, for example, made up of helical wrap spring from elastic material. Said carcass supports pack of filtration sections from elastic porous material. Said pack is made up of filtration sections with trapezoidal cross-section, squeezes in crosswise direction and glued together by their side faces. Degree of squeezing increased from OD to ID to comply with required fineness of filtration. Covers are glued to filtration section end surfaces. Pack ID and OD are selected subject to required fineness of filtration. ^ EFFECT: increased dirt capacity, longer life, simplified design. ^ 2 cl, 2 dwg, 1 ex |
