Research of the Chlorine Sorption Processes when its Deposition by Water Aerosol

Modified stepwise model of gas sorption process with finely dispersed water flow. The sorption model allows forecasting the intensity of hazardous gases deposition with adequate for the emergency recovery conditions accuracy using minimum input parameters. This allows using the sorption model under the conditions of emergency and increasing the forecasting promptness. Use of chemical neutralizer is proposed to increase the effectiveness of chlorine hazardous gas deposition. Use of sodium hydroxide is proposed as the chlorine chemical neutralizer, which is easily dissolved in water, non-toxic and easy to store. An experimental laboratory facility was developed and created with the purpose of experimental verification of the sorption processes, which allows researching the sorption processes by liquid aerosols within a wide range of dispersity. Adequacy of the existing models as well as the modified one was verified experimentally. The verification results showed a 5% indicator of the theoretical and experimental results compliance.

Metastable States of Water Aerosols: Comparison by Experiment

Free energy of water aerosol plasma was calculated using the Debye–Hückel method. It was established that free energies of droplets, ions and simultaneously of all charged particles had local minima (metastable states) at certain concentrations and charges of particles. The calculation results were confirmed by experimental data taken from the literature on a droplet cluster in water vapor and droplet structures in water fog. The possible connection of metastable states with the phenomenon of drop coalescence and rain formation in real clouds, as well as with the generation of stable spatially arranged drop structures, has been indicated.

GENERATING FIRE-PROOF CURTAINS BY EXPLOSION-PRODUCTION OF WATER AEROSOL AS AN ELEMENT OF FIRE-SAFETY ENGINEERING

Parameters of a fire-quenching system based on explosive water-aerosol production and spreading are presented. Such a system with correctly tailored amounts of the water and the explosive material produces water-aerosol with high fire-quenching efficiency due to the small radii of the droplets and at the same time secures that shock-wave pressures are safe for the human body at distances exceeding 30 m from the explosion axis.
