Abstract
A two-stage electrostatic separator for separating particles from a particle laden gas stream includes a pre-charging section and spaced-apart gas-permeable grounded and discharge electrodes charged at opposite polarities and defining a separating section between them, the grounded electrode being positioned upstream from the discharge electrode. The particles in the particle laden gas stream are pre-charged to a certain charge in the pre-charging section and penetrate through the grounded electrode into the separating section, where the particles are separated from the particle laden gas stream. As a result, a clean gas stream exits from the separating section through the discharge electrode, and the particles separated from the particle laden gas stream are partially collected on the grounded electrode, and partially are removed with a bleed flow which is recirculated. The electrodes may be of linear or cylindrical shape, and linear electrodes may be arranged in a 'zig-zag' order.
