Localized Electrostatic Precipitation as an Alternative to Exhaust Ventilation for Controlling Airborne Dust in Textile Workplaces

Abstract

We report the results of a series of investigations to assess the possible use of localized electrostatic precipitation as a practical, cost-effective alternative to local exhaust ventilation for control of airborne dust levels in the workplace. A brief summary is given of work in the laboratory using both an experimental chamber and a dust control cabinet fitted to a textile winding rig. These studies have been extended to include a pilot trial on an open-bed spinning frame in an asbestos textile factory. A detailed account of the procedures and results of this latter study is given. The possible advantages of electrostatically based systems in terms of cost-efficiency are considered against possible disadvantages associated with operational accessibility.
