ABSTRACT:
An electrostatic precipitator which operates on the principle of mutual repulsion of charged particles to a grounded wall. The solid particle laden gas stream enters a collecting section where additional particles in the form of droplets, normally water, are injected in the form of a fine spray into the solid particle laden gas stream. The solid particles and the additional particles are electrostatically charged either by conventional corona or by injecting the droplets from a charged nozzle and as the charged particles pass through the grounded section of the precipitator, a fraction of the water particles and solids are forced to the grounded wall by electric fields created by the space charge. Precipitated solid particles are entrained in the coalesced water which runs down the walls and is drained from the precipitator. Several stages of precipitation may be used or alternatively, methods such as continuously injecting additional particles into the collector along its length.
