FIELD: cleaning liquids from oil and petroleum products; chemical, petrochemical, food-processing industries; mechanical engineering. SUBSTANCE: proposed filtering plant includes housing 1, porous filtering charge 7, pressure plates 2 and hydraulic cylinder 10; filter housing 1 is made in form of parallelepiped consisting of separate sections of three types: upper section, several intermediate sections and lower section which are provided with inlet pipe unions 8 and liquid discharge pipe unions 9 and 13 and side doors 6; they are secured by means of flanges 3; lower flanges of each section form insulated chambers 4 together with pressure plates 2 interconnected by means of uprights 5; chambers 4 are used for receiving oil and petroleum products; used as filtering charge 7 are elastic perforated or screen cassettes filled with elastic porous granules or pieces of irregular shape of foam polyurethane; hydraulic cylinder 10 is located beyond housing 1 provided with gear-type oil pump 11 and buffer tank 12. EFFECT: enhanced operational reliability; increased duration of filtration cycle. 1 dwg
