EXPERIMENTAL ANALYSIS FOR WIRE-CYLINDER ELECTROSTATIC PRECIPITATOR

摘要

With the development of modern industry, the separation of suspended droplets from the gaseous flow has become increasingly important. In many industrial applications it is required to control the fine liquid droplets concentration in moving gaseous media. Refrigeration and Heating Ventilation Air Conditioning (HVAC) system is one major application. Electrostatic Precipitator (ESP) can be adopted for separation of fine droplets in gases, since corona discharge could charge these droplets, then use of electrostatic force to implement separation and collection. However, separation of droplets in gaseous flow is a complex process which is combination of electrostatic and flow field. The current study investigates effects of key parameters like applied voltage, flow temperature, flow velocity and particle's size on particles separation efficiency using a wire-cylinder assembly. Mono-disperse particles are used in this study where above mentioned parameters have shown significant effect on the separation efficiency.
