ABSTRACT:
The invention is an electrostatic device which removes pollutants from an environment, by providing a spray of electrically charged liquid droplets. The device produces the charged droplets by directing the spray through an electrostatic charging head. The charging head includes two generally concentric rings having different resistivities. The resistivity of the outer ring is preferably at least ten times greater than that of the inner ring. The inner ring is connected to a power supply, and acts as the electrode for inductively charging the droplets. Because of its comparatively low resistivity, the inner ring can conduct some electric current, and can thus act as an electrode for inducing a charge on the droplets. The outer ring, having the higher resistivity, shields the inner ring, and reduces the risk of short circuits when the material has absorbed substantial amounts of moisture.
