FIELD: air cleaning.
SUBSTANCE: invention relates to technologies for the treatment of atmospheric air for cleaning it from various volatile impurities or for saturating it with various volatile substances using granular fillers impregnated with functional substances or without them, in particular, to containers and/or cartridges containing such granular fillers. The universal container includes a box-type container with a bottom, front, back and side walls and a lid with holes made in them for air passage through them. Wherein the container lid is made with the ability to access the inside of the container, holes are made only in the lid and in the bottom of the container, on one side of the container - in the lid or in the bottom - all holes are made in the form of funnels of the same shape and size, these holes are evenly distributed over the surface. In this case, these holes are oriented with a narrow part inside the container, their total number is such that their total area on the outer side of the lid or bottom would be from 15 to 35% of the total area of the lid, the largest transverse dimension of the funnel-shaped openings d1 and the smallest transverse dimension of the funnel-shaped openings d2 are related to each other in accordance with the formula d1:d2=1:0.2-0.4, wherein the largest transverse dimension of the funnels d2 is less than the average size of the filler granule, and on the other side of the container - in the lid or in the bottom - the holes are made in the form of straight cylinders of the same size and shape with the largest transverse dimension d3, less than or equal to d2, they are also distributed evenly on the surface, and their total number is not less than the number of funnel-shaped holes on the other side of the container.
EFFECT: creation of a universal reusable container for filling granular filler, which would allow intensifying the processes of purification and/or saturation of atmospheric air, for example, simultaneously reducing air humidity and purifying it from ethylene, as well as the ability to quickly assemble prefabricated cartridges with multifunctional capabilities from separate containers.
