Abstract
A two stage electrostatic precipitator air cleaner having electric field induced airflow. A plurality of spaced parallel fin-like accelerator plates charged to a relatively high negative potential are positioned between the positively charged ionizer wires and the collecting stage of the air cleaner. The electric field induced between the accelerator plates and the ionizer wires induces an airflow for bringing the particles charged by the ionizer wires into proximity with the collecting stage while at the same time charging particles aspirated by the airflow.
Claims17
In an electrostatic precipitator air cleaner of the type having a plurality of spaced collecting plates for collecting charged particles, the spaces between said plates forming passageways having an inlet end and an outlet end, one or more ionizers positioned adjacent said inlet end, and means for charging said ionizers to a relatively high first electrical potential, the improvement comprising accelerator means positioned between said ionizers and said inlet end for producing a relatively strong electric field in the region between said ionizers and said inlet end tending to move air through said passageways and to charge particles aspirated by said moving air.
