Abstract

The data of the given research propose a new method for smog elimination in cities with temperature inversion of ground atmospheric air. This method based on device creates forced turbulence of air atmospheric volumes with different pollution levels. The device uses a two-circuit turbojet engine that captures and passes through itself the polluted air from lower atmospheric layer. The device moves a mixture of polluted air and combustion products to a height above the inversion layer, where, due to dilution in a large volume of cleaner air, the concentration of pollutants and fuel combustion products decreases to an acceptable level. The volume of the displaced polluted air is filled with clean atmospheric air. The device relates to the field of creating forced turbulence of air flows and can be used in the absence of natural resources for self-purification of atmospheric air, in cities with temperature inversion of atmospheric air near the surface. This is important from the point of view of increasing environmental safety, especially for large megacities, where polluted air from motor vehicles and the activities of powerful enterprises, in particular municipal and thermal power plants, prevails, and the high concentration of high-rise buildings (skyscrapers) interferes with normal atmospheric flows and access to fresh air for their residents. Therefore, the developed method and the corresponding device allow for effective forced air circulation of atmospheric air in large cities with a low temperature inversion layer.
