METHOD FOR AIR CLEANING, AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2015 - IPC B01D53/26 

FIELD: machine building.

SUBSTANCE: method of air cleaning involves alternate passing of air under cleaning through adsorbent located in at least two adsorbers. At that operation of one adsorber is performed in drying mode, and operation of the other adsorber is performed in regeneration mode. Regeneration mode of one of adsorbers is performed using part of air consumption dried in the other adsorber. Dry air of regeneration mode is supplied to regenerated adsorber by counter flow in relation to air flow supplied to the same adsorber in drying mode. On the way of regeneration air flow, in outlet of adsorber housing, installed is a profiled washer-filter used for formation of cavity for condensate collection. Internal surface of flange with nozzle for delivery of air under cleaning to cavity of housing with adsorbent is designed profiled, preferably conical. The top of cone is directed to nozzle inlet, and on the specified surface there made are profiled channels in the form of alternating rings of various diameters. For this method implementation proposed is a device containing at least two adsorbers with adsorbent interconnected by pipeline system. Each adsorbent includes a housing designed as a hollow cylinder, profiled flanges with nozzles installed on both ends of housing for supply and extraction of dried air, longitudinal stringers installed inside the housing, valves with control system providing switching of adsorbers from drying mode to regeneration mode, throttle with pipeline of dried air delivery under reduced pressure to regenerated adsorber and the main condensate collector with valve for moisture carrying. In pipeline system there installed is an additional condensate collector and at least in one adsorber, preferably in two ones, before the flange with nozzle for air supply to adsorber cavity there installed is a profiled washer-filter forming cavity for condensate, at that this cavity is connected to cavity of additional condensate collector. In this version internal surface of the flange with nozzle for air supply to adsorber cavity is designed profiled, preferably conical. The top of cone is directed to nozzle inlet. On the specified surface there made are profiled channels in the form of alternating rings of various diameters.

EFFECT: manufacturing drying unit with adsorber, which design allows excluding condensed moisture occurrence on adsorbent crystals.
