Predicting Vibration Performance of Collecting plates of Electrostatic Precipitators

Electrostatic Precipitator is the device used for controlling air pollution. This is used for cleaning of boiler process gases. Process gases contain suspended dust particles. These dust particles are collected on collecting electrodes. The effectiveness of Electrostatic Precipitators is affected by various factors. Periodic cleaning of collecting system plays a major role. Dust gets deposited on collecting electrodes and dislodged by means of vibrations of collecting electrodes. For huge volume of process gas the size of Electrostatic Precipitator will also be large. Since space is major constraints the ultimate solution will to go vertically i.e. increase the height and accordingly the collection area. Since the height is increased old methods of rapping will be ineffective and hence the new methods introduced to increase the vibration. On the basis of vibrations and forces on the collecting plate, the vibration performance of collecting plate of Electrostatic Precipitator will be estimated by using finite element analysis (FEA). The current study focuses on definite amount of vibrations in the collecting plate of Electrostatic Precipitator. The effect of producing vibrations in the collecting plate was studied at different height of Rapping Hammer. A finite element method based on the software ANSYS used to simulate the vibrations produced in the collecting plate. In order to validate result of Finite Element Software Experimental testing is required .The overall objective of this project is to produce definite amount of vibrations in the collecting plate of Electrostatic Precipitator for different height of collecting plate. This study will be helpful in understanding the Dynamic performance of Electrostatic Precipitator in the Environmental engineering.
