FIELD: process engineering.
SUBSTANCE: invention relates to photocatalytic air cleaning and may be used at chemical enterprises and in clearing effects of acts of terrorism. Air is cleaned and decontaminated by oxidation with the help of titanium dioxide-based catalyst UV radiation source. Aerosol cloud 10 of titanium dioxide nanopowder 3 is used as said catalyst and aerated and sprayed from container 1 prefilled with combustion products of gas generator 4 with a charge of low-temperature solid propellant 5. Radiation sources 6 and 7 are arranged regularly along periphery of said cloud 10.
EFFECT: efficient in-situ cleaning and decontamination.
