Abstract RU 2682558 C1

FIELD: technological processes.

SUBSTANCE: invention relates to self-cleaning filters of continuous action and can be used in power engineering and other industries for filtration of water and other liquids. Self-cleaning filter comprises vertically mounted cylindrical housing with lower bottom and flange joint at its top. Cylindrical filter element with blind lower bottom and top bottom communicated with filtered fluid discharge branch pipe is arranged concentric with said casing. In space between filter housing and filtering element along longitudinal axis of filter there is a dead partition separating said space into two cavities. Each cavity is connected to its inlet branch pipe for liquid to be filtered, and to discharge the liquid in countercurrent washing of the filter element.

EFFECT: compact design of the filter without electric and other drives, without rotating or moving parts, capable of operating at the required pressure of the filtered liquid.
