FILTER Russian patent published in 2007 - IPC B01D46/02 

FIELD: filtering engineering.

SUBSTANCE: filter comprises housing provided with a lid, section for cleaned air, filtering section that receives filtering members each of which has frame and filtering element, inertia dust separator of shutter type, hopper, and inlet and outlet branch pipes. The inlet branch pipe of the filter underlies the filtering section whose hydraulic resistance is no more than 50% of the hydraulic resistance of the total filter. The inertia dust separator is mounted coaxially to the housing of the filter and underlies the baffle that separates the filtering section from the hopper. The space between the housing of the filter and dust separator is no less than one tenth of the diameter of the housing. The bottom open ends of the filtering members are secured to the rigid baffle. The section for cleaned air receives the system for regeneration of the filtering members provided with the mechanism for removing dust by vibration and unit for control of regeneration. The mechanism is mounted on the top dummy flanges of the filtering members. The unit for control of regeneration is connected with the common microprocessor that controls the process of filtering.

EFFECT: enhanced efficiency and reliability.
