ABSTRACT:
Parameters for optimum operation of a pulsed multisection electrostatic precipitator are disclosed: It has been discovered that superior particulate collection can be achieved by a combination of pulse and conventional DC voltages. The pulse rise time and decay time are made short enough so that adverse sparking conditions do not develop. The base voltage (conventional DC voltage) is adjusted in coordination with the superposed pulse characteristics (pulse voltage, pulse frequency and pulse shape) to maintain an average current through the collected dust layer just below or at that value which would cause electrical breakdown of the dust layer. Base voltage may actually be below normal corona starting voltage in some cases. The pulse produces instanteously very high ion densities and electric field strengths. In one design of precipitator, alternate sections are pulsed, with the other alternate sections functioning as collecting sections and merely having DC base voltage applied thereto. In other designs, all sections including the collecting sections, may be pulsed to provide sufficient current to hold the collected particles on the collecting surfaces and to prevent reentrainment. In some designs, at least one of the sections may be a transmission line which is pulsed.
