COMBINATION OF FILTER AND ELECTROSTATIC SEPARATOR

摘要

A device and method for controlling particulate air pollutants of the presen t invention combines filtration and electrostatic collection devices. The invention includes a chamber housing a plurality of rows of filter elements (24). Between each row of filter elements (24) is a grounded plate (26). Between the grounded plates (26) and the filter elements (24) are electrode grids (28) for creating electrostatic precipitation zones between each row o f filter elements (24). In this way, when the filter elements (24) are cleaned by pulsing air in a reverse direction, the dust removed from the bags will collect in the electrostatic precipitation zone rather than on adjacent filt er elements (24).
