FIELD: chemistry. ^ SUBSTANCE: invention can be used in closed loop life support systems, in processes for treating dry feed mixtures with ozone. A fan 2 feeds air into ozoniser 1, in which ozone forms from oxygen under the effect of electric discharge. The output of the ozoniser is connected to the inlet flange of the fan by a bypass tube 3. A diaphragm 4 and a return valve 5 are fitted in the bypass tube. If flow of the ozone and air mixture at the output of the ozoniser 1 falls due to increase of pressure inside the ozoniser, part of the mixture is fed to the input of the fan 2 of the ozoniser through the bypass tube. ^ EFFECT: easier regulation and maintenance of ozone concentration when air flow changes. ^ 3 cl, 2 dwg |
