Model range of neutralizing aerosol sprayers using HEMs
Currently, the danger of environmental and terrorist threats associated with aerosol emissions of hazardous substances, as well as the spread of biological aerosols carrying bacteria and viruses, is growing. Therefore, it is necessary to develop new methods and devices to quickly neutralize such emissions. Spraying a neutralizing aerosol using HEM energy has a number of advantages associated with a high rate of aerosol generation and a high dispersion of neutralizing particles. The high dispersion of the particles provides them with a large specific surface, which increases the efficiency of their interaction with harmful substances in the air. The paper proposes a number of atomizers based on HEM. Some of them allow you to spray powders for adsorption or catalytic neutralization of harmful substances. Others create a cloud of liquid droplet neutralizing aerosols (such as disinfectants to kill viruses and bacteria). The third approach is the development of special nanothermic mixtures containing a disinfectant. When such thermite burns in the air, a cloud of disinfectant vapors is formed. The results of experiments on the spraying of nanostructured titanium oxide, a disinfectant liquid, are presented. In the experiment, the concentration and particle size of the sprayed aerosol were determined in real time. It has been experimentally and theoretically shown that the sprayed particles have a mass-average diameter of less than 1 pm and remain in the air for at least 10 minutes. A series of experiments was carried out to create an iodine vapor cloud using iodine-containing nanothermites. It has been shown that the use of iodine-containing nanothermites can significantly reduce the microbicidal activity of lactobacilli.Further work will be related to improving the efficiency of the proposed devices. For this, mathematical models will be developed that describe the interaction of titanium oxide particles with harmful substances, and describe the death of microorganisms under the action of disinfectant vapors. The most effective iodine-containing nanothermic compositions for the disinfection of indoor space will be developed. The authors declare no conflicts of interests.
