  • Electrostatic precipitator with rapper and pneumatic flow blocking
    Patent number: 3988130
    Abstract: An electrostatic precipitator is disclosed which is provided with a plurality of gas jets which upon activation repulses the normal gas flow through the electrostatic precipitator during cleaning to create a quiescent condition to reduce further dispersion of the loosened particulate layer into the outlet stream. A control system for operating the jets and the discharge and collector plate rappers is shown.
