Electrostatic Precipitator and Its Cleaning System for Small Scale Combustion

This paper Design and Implementation of an Electrostatic Precipitator and Its Cleaning System for Small Scale Combustion.

It is a simple wire-plate electrostatic precipitator (ESP) that was constructed in order to test the efficiency of collecting smoke particles from the combustion of rubber wood that is used as a source of biomass energy.

The ESP contains a collection cylinder electrode and 2 wire electrodes between the cylinder. The maximum input voltage of the Wheatstone bridge circuit using a high-voltage neon transformer was 10.5 kV (DC).

The gap between the cylinder and the distance between wires was adjustable. Results from the field test in a furnace indicate that the device could be used for a period of about one hour before cleaning the electrodes was required.

The collection efficiency was decreased during the course of wood-burning as the dust loading increased. Maximum efficiency was near 80% during the initial period.

The distance between the collection plate electrodes had a greater influence on efficiency than the distance between the wire electrodes.

The cleaning system used in this experiment was made from a row of PVC pipes to allow water to discharge radially to the cylinder electrodes on both sides. Efficiency was increased after 120.

This ESP is suitable for small and medium-sized enterprises (SMEs) to alleviate the release of detrimental chemicals such as PAHs into the atmosphere.
