Numerical Study of Half Wavy and Half W-type Collecting Plates on the Characteristics of Electrostatic Precipitators

Many industries rely heavily on ESPs (electrostatic precipitators). They exist primarily as air filters to prevent hazardous particles from entering the environment. Duct-type ESPs are widely used, have a simple design, and rely on corona wires and collecting plates as their primary arrangement. Numerous studies have been conducted to demonstrate that changing the geometrical shape can aid in improving particle collection efficiency. Wavy plates, W-types, and other designs, for example, have shown to improve particle collection efficiency in a positive degree. The goal of this study is to see what happens when two different types of collecting plates are combined and used together. The proposal is to combine half wavy and half W-type collecting plates and examine them with corona wires with circular shapes. As a result, after completing the numerical study and comparing the results, it is clear that the levels of particle collection efficiency for the various particle sizes have increased with this proposed design. Furthermore, six cases are presented with this design, and the results describe the electrical properties and their magnitude distributions. In fact, in all of the cases presented, this type of combination increased particle collection efficiency.
