摘要： An electrostatic precipitator (1) has a last field (14) being provided with discharge electrodes (16), collecting electrodes (18) and a rapping device (22), which is adapted for cleaning the collecting electrodes (18) by means of rapping them. A control system (30) for controlling the dust particle emission from the electrostatic precipitator (1) comprises a control device (38), which is operative for adjusting, based on a relation between a magnitude (H) of a selected dust particle emission peak caused by a selected rapping and the time (t) between said selected rapping and its immediately preceding rapping, at least one parameter chosen from the group of: the time (t) to elapse until a rapping is to be executed in the last field (14), and the type of rapping to be executed in the last field (14).

摘要： A method for controlling an electrostatic precipitator unit, which comprises discharge electrodes and collecting electrodes. Between the electrodes a varying high voltage is maintained by a pulsating direct current supplied thereto. Dust deposited on the collecting electrodes is removed by mechanical rapping during recurrent, relatively short rapping periods separated by rapping intervals of essentially longer duration. During the rapping period, the voltage between the electrodes is reduced in relation to the voltage between the electrodes during the intervals between the rapping periods. The frequency, pulse charge and/or pulse duration of the pulsating direct current are varied, thereby obtaining a plurality of combinations of frequency, charge and duration. A combination of frequency, charge and duration which is optimal to the operation of the precipitator unit is determined. One or more of the parameters rapping frequency, rapping force, number of raps per rapping period, and current or voltage during the rapping period are adjusted in dependence on the pulse frequency of the established optimal combination of frequency, charge and duration.

摘要： A multiple rapper control (10) for an electrostatic precipitator for monitoring and individually controlling each of a plurality of rappers based on computer (12) stored rapper characteristics including the voltage type, the voltage level, the pre-set electrical input current, the minimum increment between energization cycles, and the maximum duration of energization. Each rapper is connected to a TRIAC switch device (20) linked to a computer (14) and a power control means (16) to vary the input power to each rapper supplied from a power source (18). Current detecting means (22) is bi-directionally connected to the computer (14) and is connected to the power control means (16) to sense and measure the peak electrical input current to each rapper. A preselected logic sequence stored in the computer (12) controls power to each rapper. Optional polarity reversal means (37) eliminate undesirable magnetization of rapper components.
