METHOD OF THE AIR CLEANING OF CARBON DIOXIDE AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2018 - IPC A62B11/00 

FIELD: rescue service.

SUBSTANCE: group of inventions refers to the field of air purification from carbon dioxide in hermetically sealed rooms in the event of emergency situation in the absence of electricity. Method of the air cleaning of carbon dioxide in hermetically sealed rooms, according to which the carbon dioxide absorption is carried out by a chemical absorber, which is suspended in a room. According to the invention, carbon dioxide chemical absorber in the form of a sheet material is produced by the absorbent composition application onto the fibrous substrate, comprising calcium hydroxide (mass fraction is not less than 60%), potassium and / or sodium hydroxide, water and polymer binder in the form of sheet material with a thickness of no more than 2 mm, wherein the sheets are joined together by ties creating a three-dimensional structure in the suspended state. Air purifying from carbon dioxide device in hermetically sealed spaces, contains a housing, into which a container with a chemical absorber is placed. According to the invention, the container is made in the form of a gas-tight enclosure, in which the carbon dioxide chemical absorber is placed in the form of a sheet material which, for use, is unfolded into the three-dimensional structure in the form of a vertical festoon.

EFFECT: group of inventions provides a simplification of the method and improvement of the air purification from carbon dioxide efficiency, as well as an increase in the packing density and ease of the air purification from carbon dioxide device bringing into operation position.
