METHOD AND DEVICE FOR AIR PURIFICATION USING A REGENERATED CO ABSORBER Russian patent published in 2022 - IPC B01D43/00 B01D53/04 B01D53/86 A61L9/20 A62B11/00 

FIELD: air purification.

SUBSTANCE: group of inventions relates to means of purifying air and maintaining standard levels of carbon dioxide in the air for breathing in confined spaces. The purification method involves blowing air through a regenerated carbon dioxide absorber. The absorber is made in the form of activated carbon granules impregnated with an aqueous solution of diethylamine. Preferably, the absorber is placed in several layers in a cartridge with mesh walls to ensure its purging, essentially evenly by volume. The air is additionally disinfected with a UV emitter with radiation wavelengths of more than 185 nm located upstream from the absorber. After the absorber, the purified air is enriched with a complex of microelements that are part of sea or mountain salt. Regeneration and disinfection of the absorber is carried out by heating it to a temperature of at least 65°C with a stream of hot air. The concentration of CO₂ in the air of a limited space is maintained automatically in a given range. The method is carried out using an air purification device.

EFFECT: group of inventions makes it possible to expand the arsenal of means to improve the efficiency and quality of air purification.
