Particle distribution analysis along the collection electrode of a 'wire-to-cylinder' electrostatic precipitator

摘要

This study determined the value distribution of the 'charge/mass' ratio of the particles charged by corona along a 'wire-cylinder' electrostatic precipitator (ESP). These particles are absorbed by suction from the openings on the collection electrode. The results enabled the analysis of the particle movement in the ESP. For moderate voltage values (8-12 kV), the constant ratio along the ESP suggests that the product is uniformly collected when the particles acquire a sufficient electric charge during their progression. Conversely, for higher voltages (14-16 kV), massive deposition occurs at the inlet as soon as the particles are sufficiently charged.
