Abstract
An electrostatic precipitator arrangement comprises an oscillating circuit in which the precipitator is included as a capacitor, the circuit also including a storage capacitor and pulse initiating means, such as a thyristor or a spark gap, for causing the energy stored in the storage capacitor to oscillate from that capacitor to the precipitator and then through a diode or other electric valve means having the opposite direction of conduction back to the storage capacitor.
Claims7
An electrostatic precipitator circuit, comprising:
- a voltage source for generating a unidirectional voltage;
- precipitator electrodes constituting a capacitor and responsive to said inidirectional voltage;
- a pulse generator including a storage capacitor for generating pulses;
- inductance means intercoupled between said storage capacitor and said precipitator electrode capacitor for transferring said pulses to said precipitator electrodes in superimposed relationship to said unidirectional voltage;
- said storage capacitor, inductance means and said precipitator electrode capacitor forming a controllable LC oscillating circuit;
- and
- non-linear electric means for controlling said LC oscillating circuit to enable the energy stored in said precipitator electrode capacitor during each pulse transferred thereto to return to said storage capacitor for renewed storage therein.
