METHOD OF AIR CLEANING Russian patent published in 2015 - IPC B01D53/26 B01D53/04 

FIELD: process engineering.

SUBSTANCE: invention relates to separation of disperse particles from gas flow. Proposed process consists in forcing air to be cleaned through adsorbent fitted in two adsorbers. Note here that first adsorber operates as a drier while second one runs as a regenerator. Regeneration of the absorber is executed by portion of air dried in the other adsorber. Dry air of regeneration is fed to regenerable adsorber in counter stream relative to air fed to this adsorber at drying conditions. Shaped washer-filter is arranged on the path of regeneration airflow at adsorber housing outlet to make the condensate collection chamber. Flange inner surface with air feed union is shaped, mainly, to cone. Note here that cone vertex faces the union inlet. Note also that said surface is provided with shaped grooves composed of alternating different-diameter rings.

EFFECT: efficient cleaning, protection of adsorber against contact with drop moisture, longer life.
