Abstract

The apparatus includes a grounded fiber bed 12 of 50 to 1000 mlcron average diameter fibers packed to a bed voidage of from 90% to 98%, an electrostatic field means 8, 10 upstream of the fiber bed to place an electrical charge on the particles, and irrigation means 14 for the fiber bed and optionally for the grounded electrodes 10 of the electrostatic field means as well, to flush collected particles from the fiber bed and optionally from the grounded electrodes. The process is suitable for separation of any particles but is particularly advantageous for separation of insoluble solid particles from gas streams at high bed velocities of from 1.8 to 4.6 or more meters per second. In the process, particles are charged in the electrostatic field means and the charged particles are collected in the fiber bed where the electrical charge is dissipated through the irrigating liquid/particles mixture so that no significant space charge effect is allowed to develop in the fibers of the fiber bed and re-entrainment of particles is avoided. The discharge electrodes 8 are rods having points projecting alternately from each side, parallel to the plates 10. <IMAGE>
