The Principles of the Layout and Evaluation of Systems for Protection from Dust Pollution of the Air

The technical condition of vehicles directly depends on the condition of highways. Maintaining the quality of the pavement will ensure the reduction of overhauls. The use of dust collection systems in the technological process for laying the asphalt concrete pavement and other layers of the pavement construction will provide protection against dust pollution of atmospheric air. A significant part of modern technological processes are associated with the manufacture, processing, transportation and use of powdered materials, and is accompanied by intensive release into the atmospheric air of significant amounts of dust. In the current environmental situation, even at relatively low initial concentrations, it increases the technogenic impact on the surrounding environment, and also entails the loss of valuable components and the increased costs of air treatment in ventilation and air conditioning systems. In the prevailing practice of design and operation, multistage plants for cleaning industrial emissions from suspended solids have become the most widespread. The article provides a systematization of the basic principles of the layout of such systems, as well as a calculation for a preliminary evaluation of their effectiveness using the example of a dust collection system proposed for the production of aerated concrete.
