“…The process of shielding dust particles with a foam layer is characterized by the efficiency E ef(2) -n which value depends mainly on the properties of the foam and the speed of the meeting of the dust particles with the foam bubbles. Taking into account the results of the experimental and theoretical studies presented in [14,15] with respect to the foam layer the quantity E ef(2)-dr is determined by the formula:…”

The physical essence of the reducing air pollution hydrodynamic method by means of the foamy method as the most effective dust retention technology for open long sources at construction industry enterprises is presented in the article. The mathematical description of this technology has been performed, taking into account the physical and chemical properties of the dust and foam bubble, as well as the parameters of the return of dust particles to technological raw material due to various physical mechanisms for their capture. The obtained parametric dependence of dust retention efficiency provides the possibility of its predicted calculation as a resultant parameter for the considering technology, taking into account the interaction of dust with a foam layer.

“…3010 dust particles with certain bubbles of foam layer, which could be described with the following dependence: (1) where Е eff(1)-dr -is the efficiency of capture and return of dust particles by the foam layer into the stream of technological raw material under the influence of inertia forces; Е eff(2)-dris the efficiency of elastic interaction (repulsion) of dust particles with foam bubbles; Е eff(3)-dr -is the efficiency of capture of dust particles by foam bubbles under the influence of electric forces.…”

“…Analysis of experimental data [8] allowed to obtain the dependence of efficiency of capture of dust particles under the influence of electrical forces which we use in calculation in relation to foam method in using foam layer: (3) where q 0 -is electrical mass per charge unit of foam, Kl/m. It should be noted that for artificial electrilization the value of electrical mass per charge unit q 0 depends on the method of foam recharging and potential value [1].…”

Abstract.The article provides the analysis of the physical essence and simulation of the process of dust retention with foam in the air of working zones of belt conveyors transporting sand, crushed stone, gravel, coal, grain. In accordance with the proposed physical-energy concept of simulation of the process of dust control its physical essence is in a deliberate sequential action on the dust particles with previously prepared by the parameters external (additional) dispersed systems. Use of dust retention technology foam method provides high efficiency of reducing the concentration of dust in the air of working areas of belt conveyors, which varies in the range of 85.0-99.0 %, which provides the standard level of dust contamination (MPC) in air of working areas of listed industrial sources of formation and emission of dust.

“…However, the need to solve a complex of tasks dealing with dynamics of air pollution control becomes more topical every year. This is due to the factors of material and physical pollution in the current context of urban development which are the most concentrated in the air basin of their territories [1, 2,3]. The toxic components (nitrogen oxides, carbon monoxide, sulfur oxides, benz(a)pyrene, particles of ash and sootflakes) of exhaust and effluent gases of power units of plants, as well as public and domestic power units have a particular negative effect [4].…”

The article describes the air purifying device of the “OTPO-9” type, which implements the technology of hydrodynamic purification with a foam method where foam was produced by bubbling. The article considers it as the most environmentally efficient and energy-saving device, based on the results of implementation of the methodology of technology selection for purifying exhaust and effluent gases from toxic components of industrial, public and domestic power units up to 1000 kW developed by the authors. The full-scale laboratory studies of the semi-industrial model of the developed device were carried out by the authors. These studies allowed us to define the nitrogen oxide and sulfur removal efficiency depending on the electric voltage, the shape of the device’s side wall in layout, the submersion of inlet and outlet pipe side holes, the ratio of the anode total area to the cathode one. Moreover, the authors have revealed the device scope of application and its advantages. The article states that the proposed device provides environmental safety of the implementation process in comparison with the use of chemical alkaline solutions, which are dangerous for human health and environment.
