The main objective of this work is to study the behavior of fine dust fractions (aerosols) of different nature in a non-uniform electric field (corona discharge) under electric, gravitational, aerodynamic and other disturbances. Determination of fundamental principles, and development of methods for controlling fine-fraction particles with predetermined physical characteristics. This article also presents the results of practical application of the developed methods.

The main fundamental objective of this work is the research of behaviour of fine dust fractions (aerosols) of various nature in non-uniform electric field (the crown category) in the conditions of action of electric, gravitational, aerodynamic and other indignations. Determination of the fundamental principles and also development of methods of management of particles of fine fraction with the set physical characteristics will allow to develop adequate mathematical behaviour models of aerosols in nonuniform electric field. In the real work mathematical modelling of electrostatic field in the device is described and the mathematical model is presented. The analysis of physical processes in the device of blocking of dust emissions – “an electrostatic lock” taking into account influence of Aerodynamic effort is carried out from such phenomenon as “Ionic wind”.

In this scientific work the new method of electroseparation by means of impact on a dust fraction of the crown charge is considered. The presented device for the electromechanical separation is the main competitor for systems of the electrostatic, crown, dielectric, triboadhesion separation widespread in the industry today. Use of the electromechanical device for crown separation allows separation of fine particles with the set dimensional and physical characteristics from the stream. The main attention in the article is paid to the research of a fine fraction behaviour in the non-uniform electric field. Mechanisms of the impact of electric, gravitational, aerodynamic and other disturbances on the dust fraction (aerosols) are considered in detail. The system of the equations describing physical processes of the movement of a dust particle in the non-uniform electric field taking into account influence of the aerodynamic effort created by the "ionic" wind is presented in this work.

The Multi Stage Collector (MSC™) concept for ultra-fine particulate control not only retains the best advantages of current state-of-the-art technology but also makes significant improvements. The new MSC™ design provides a synergistic combination of both single- and two-stage electrostatic precipitation while incorporating an additional collector-stage by filtering the gas exiting the collector through a barrier collector-zone. This arrangement ensures that essentially all dust would be detained in this final stage. The MSC™ contains multiple narrow and wide zones formed by a plurality of parallel corrugated plates. Enclosed in the narrow zones are discharge electrodes. These electrodes provide a non-uniform electric field leading to corona discharge. The corona discharge causes particulate matter in the gas flow to become charged. Wide regions contain barrier filters thus creating the two-stage precipitator with relatively uniform electric field. In these regions, particles are collected on both plates and on the porous barrier elements, which also act as the final filtering stage. Results of the applications analyses and future development work are discussed. The gas flow analyses with an aid of the CFD model are presented below.
