The effects of the corona wire distribution with triangular collecting plates on the characteristics of electrostatic precipitators

Numerical Study of the Influence of Using Semicircular Corrugated Collecting Plate and Inverted Semicircular Corrugated on the Electrostatic Precipitator

“…In ESP, the electric field is non-uniform. It can be solved quantitatively using the Poisson equation and the charge-conservation equation, which are written in terms of electric potential and space-charge density [1][2][3][4][5][6]:…”

“…The RNG technique and the k-epsilon turbulence model are then employed to establish an incompressible, stable, and turbulent flow as Eqs. ( 7)-( 9) [1][2][3][4][5][6]. High Reynolds numbers (Re) characterize turbulent flows, which can be solved by applying the Reynolds-averaged Navier-Stokes (RANS) equations.…”

“…( 20), we find the definitions of these two classes of forces . Because of the attractive forces between charges of different poles, charged particles will rush to the collecting plates when electrical forces are present [1][2][3][4][5][6]. Until they were charged, the particles would naturally go in the direction of the gas flow.…”

“…ESPs are generally utilized in a variety of industrial applications to collect particles that shouldn't be released into the atmosphere. Although while the particle removal efficiency for small particles (approximately 0.2 μm) has been very low, ESPs can achieve above 99% efficiency and need relatively little energy to operate [1][2][3][4][5][6].…”

“…Particles are charged by the discharge electrodes and are then attracted to and collected by the collecting plates, which have the opposite charge [7]. Ionization is achieved with the use of a high-voltage power source, and the cleaning mechanism gets rid of the particles that have accumulated on the plates [1][2][3][4][5][6]. Electrostatic precipitators (ESPs) can be categorized into two types based on the number of stages and the geometric configuration of their collection plates.…”
