METHOD OF PURIFYING AIR MIXTURE IN SURGERY AND MATERNITY BLOCKS FROM PATHOGENIC MICROFLORA, HIGHLY VOLATILE ORGANIC AND CARCINOGENIC SUBSTANCES AND RECOVERING OXYGEN IN CLOSED ROOMS Russian patent published in 2014 - IPC B01D53/84 

FIELD: chemistry.

SUBSTANCE: air mixture is forced into a purification system and purified step by step: first, the air mixture passes through carbon-fabric filter, then through a carbon filter and a chemisorptive filter; further, the mixture is fed into a cavity adapted to create turbulent air flow, which is fitted with monochromatic emitters in the ultraviolet and blue regions; after light exposure, the mixture is purified by passing through a calcium peroxide filter while entering the next cavity which is adapted to create turbulent air flow, and then purified by a carbon-chemisorptive filter and a cotton-fabric filter.

EFFECT: multi-step purification.
