FINE FILTER Russian patent published in 2013 - IPC B01D29/66 B01D35/12 

FIELD: process engineering.

SUBSTANCE: invention relates to automated filters and may be used in power generation, transport, and other industries for fine cleaning of fuels, oils and other fluids. Fine filter comprises casing, bottom chamber, contaminated medium feed branch pipe and purified medium discharge branch pipe, blowback pipeline, cover supporting geared motor bed and filtration chambers with filtration elements. Purified medium chamber is arranged inside said casing. Said contaminated medium feed branch pipe and purified medium discharge branch pipe are arranged at one axis inside casing top part. Tubular filtration elements feature preset fineness of filtration, porous structure and are made from sintered stainless steel gauze with porosity of 30-80%. Filtration occurs from outside to inside. Air receiver is mounted on cover and communicated via compressed air feed pipeline with every filtration chamber. Shaft-manifold set composed of stepped shaft and manifold welded thereto is arranged along unit axis of symmetry. Said manifold is located in casing, under purified medium chamber. For filtration chamber regeneration, blowback pipeline positioning assembly is installed.

EFFECT: high quality filtration of larger volumes, ease of servicing.
