ROTARY FILTER FOR GAS PURIFICATION Russian patent published in 2014 - IPC B01D46/02 B01D45/12 

FIELD: machine building.

SUBSTANCE: rotary filter for gas purification comprises a vertical cylindrical housing with a conical bottom fitted by a connecting pipe to remove dust, a rotating exhaust pipe with its lower part made from porous material which is placed below the connecting pipe for the supply of dust-laden gas and serves as a filtering element, a connecting pipe to withdraw purified gas, a connecting pipe to supply the dust-laden gas to the device set tangentially to the housing, a cover with a connecting fitting, a wind wheel to rotate the exhaust pipe set at the level of the connecting pipe for the supply of dust-laden gas flow downstream the gas flow. Cross partitions are installed at the angle of 25-35° to the symmetry axes on the filter housing at the level of the porous part of the exhaust pipe, it is done so that to provide for clearance between the filtering element and the partitions ensuring the tangential motion of the dust-laden flow in respect to the filtering element with the velocity of 25-75 m/s and allowing for the continuous regeneration process.

EFFECT: invention provides for continuous regeneration of filtering surface of an exhaust pipe, higher efficiency of dust-laden gas system separation due to increased radial component of dust particle velocity, small dimensions of a device due to the usage of workspace for centrifugal purification and filtering of dust-laden gas, simple manufacturing and reliable performance, lower power consumption for filtering process.
