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.

Particulate Control

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.
