A purification canister for a gas mask and a gas mask including peroxy radical reaction tube for removing pollutant

摘要

A gas mask and a gas mask for gas masks having a photocatalyst coated UVLED reaction tube for removing harmful pollutants are disclosed. Gas purifying container according to the present invention, the physical filter including a filter paper (filter paper) to remove by filtering harmful pollutants; A chemical filter comprising activated carbon for chemically removing the harmful pollutants; And a photochemical reactor for generating peroxyl radicals by irradiating ultraviolet rays to the photocatalyst and removing the harmful pollutants by using the generated peroxy radicals. The photochemical reactor includes a reaction tube having an inner wall coated with a photocatalyst and removed by the peroxy radicals while the harmful pollutants flow through the inside; And at least one ultraviolet lamp (UV LED) for irradiating the ultraviolet rays to the inner wall of the reaction tube. The reaction tube may be bent at one or more places. The reaction tube may be bent in a "c" shape.
