В роботі запропоновано об’єкти захисту повітряного басейну міст примагістральних територій шляхом очищення повітря з використанням озонових технологій. Наведено принципову схему установки, основа якої мокрий пиловловлювач. Введення озону в потік води споруди сприяє миттєвому доокисленню шкідливої газової складової оксиду азоту. Показана модель територіального розподілу зон дії очисної споруди і наведені основні умови роботи очисної споруди на міських територіях.

Title in English

AIR PROTECTION OBJECTS OF CITY TERRITORIES

English abstract

One of the main problems of environmental impact is air pollution by vehicle emissions. The average person consumes about 25 kg of air per day, any pollution can cause serious diseases. Previously, plants coped with a certain mass of pollutants (in the process of photosynthesis, accumulation of carbon, and other harmful elements), now the difference between pollution and purification is incomparably higher. Therefore, additional measures, such as treatment facilities, are needed to protect the air basin from anthropogenic impacts, especially along highways. The proposed object of air protection, which relates to a method of reducing dust and nitrogen oxides in polluted air and can be used to clean the polluted air of urban areas, namely near urban highways from the most dangerous solid impurities and nitrogen oxides. The basis of the proposed treatment facility is a wet dust collector, which is characterized by high cleaning efficiency from a fine dust up to 2 μm and works on the principle of deposition of dust particles on the surface of the droplets under the action of inertia or Brownian motion. The introduction of ozone into the water flow of the structure promotes instant oxidation of the harmful gaseous component of nitric oxide and reduces its content to 70%. The proposed method provides a certain effect on the purification of air on urban highways, polluted by exhaust gases of vehicles, and does not require large material costs in its implementation. The model of territorial distribution of zones of action of a treatment facility is calculated. The level of air pollution on highways, especially near regulated intersections, is one of the highest compared to the level of pollution near other sections of the road network, so there is a need to install two or more treatment facilities. The main conditions of operation of the treatment facility in urban areas are given. The main prerequisite is the excess of air pollution in the main near-highway city territories, which varies depending on traffic and weather conditions. A sufficient condition is the availability of utilities and urban indicators.
