Abstract
Abstract Covers an electrostatic precipitator and mechanism associated therewith for collecting dust, dirt and other particulate matter received by the electrostatic precipitator. The electrostatic precipitator may include two or more apertured plates or grids which are vertically oriented and positioned parallel to each other and arranged so that air or gas laden with the particulate matter will traverse the apertures. The alternate grids may be connected to one terminal of a high voltage source while the other or adjacent alternate grids may be connected to the other terminal of the same source of voltage and grounded. The last grid, i.e., the downstream grid of the series, may be equipped with a tray for receiving the collected dust. The collected dust will reach the tray only after it has been deposited on the grid to which the tray is attached. The collected dust is dislodged from the grid under the influence of the stroke or strokes of a rapper. The tray preferably may be inclined at a predetermined angle so that dust received in the tray may be caused to move downhill along the tray and then discharged into a hopper. A vibrator may be employed to produce repeated blows against the surface of the tray to assist in the removal of the particulate matter.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
128 words
Electrostatic precipitator apparatus comprising a substantially vertical element having a plurality of perforations through which are transmitted substantially horizontally a gaseous medium bearing particulate matter and such particulate matter may be electro-deposited on said element, the perforations being of such a size as to freely pass the particulate matter without becoming clogged thereby, a tray affixed to the downstream side of said element in a horizontal or nearly horizontal position and extending over substantially the entire width of said element so that it may receive particulate matter electro-deposited on said vertical element and thereafter released from said vertical element above the position of the tray, and a rapper positioned higher than the tray for periodically mechanically rapping the vertical element to release particulate matter from the vertical element.
Claim 2
Dependent Claim
128 words
Electrostatic precipitator apparatus comprising a substantially vertical element having a plurality of perforations through which are transmitted substantially horizontally a gaseous medium bearing particulate matter and such particulate matter may be electro-deposited on said element, the perforations being of such a size as to freely pass the particulate matter without becoming clogged thereby, a tray affixed to the downstream side of said element in a horizontal or nearly horizontal position and extending over substantially the entire width of said element so that it may receive particulate matter electro-deposited on said vertical element and thereafter released from said vertical element above the position of the tray, and a rapper positioned higher than the tray for periodically mechanically rapping the vertical element to release particulate matter from the vertical element.
Claim 3
Dependent Claim
31 words
Electrostatic precipitator apparatus according to claim 1, in which the tray is affixed to the vertical element at a small predetermined angle, such as about 10*, with respect to the ground.
Claim 4
Dependent Claim
26 words
Electrostatic precipitator apparatus according to claim 1, in which the rapper consists of a vibrator adjacent to the tray for applying mechanical vibrations to the tray.
Claim 5
Dependent Claim
144 words
Electrostatic precipitator apparatus comprising a plurality of substantially vertical plate elements which are substantially parallel to each other and electrified so that adjacent elements are oppositely polarized, each of said vertical elements having a plurality of openings through which a gaseous medium bearing particulate matter may be transmitted substantially unidirectionally and substantially horizontally through the openings of said vertical elements and, due to the electric fields between the vertical elements, such particulate matter may be deposited on said vertical elements, the openings being of such size as to freely pass the particulate matter without becoming clogged thereby, a stationary tray positioned downstream of said vertical elements and substantially horizontal, so that the tray may receive particulate matter released from said elements, and means for vibrating said tray so as to facilitate the movement along the tray of the particulate matter received by the tray.
Claim 6
Dependent Claim
144 words
Electrostatic precipitator apparatus comprising a plurality of substantially vertical plate elements which are substantially parallel to each other and electrified so that adjacent elements are oppositely polarized, each of said vertical elements having a plurality of openings through which a gaseous medium bearing particulate matter may be transmitted substantially unidirectionally and substantially horizontally through the openings of said vertical elements and, due to the electric fields between the vertical elements, such particulate matter may be deposited on said vertical elements, the openings being of such size as to freely pass the particulate matter without becoming clogged thereby, a stationary tray positioned downstream of said vertical elements and substantially horizontal, so that the tray may receive particulate matter released from said elements, and means for vibrating said tray so as to facilitate the movement along the tray of the particulate matter received by the tray.
Claim 7
Dependent Claim
22 words
Electrostatic precipitator apparatus according to claim 4, including means for vibrating said vertical plate elements so as to release particulate matter therefrom.
Claim 8
Dependent Claim
129 words
Electrostatic precipitator apparatus for removing particulate matter borne by a pressurized gaseous medium moving substantially unidirectionally, comprising a plurality of substantially vertical perforated plates which are substantially parallel to each other and subsTantially perpendicular to the path of the gaseous medium, said plates being polarized so that such particulate matter traversing the perforations of said plates may be attracted to and collected on said plates, elongated receptacle means in the form of trays affixed to said plates and positioned downstream of said plates and substantially parallel or nearly parallel to the ground for receiving particulate matter released by said plates, and rapping means for mechanically rapping each selected perforated plate, and vibrating means for mechanically vibrating each tray for facilitating the movement of particulate matter received by each tray.
Claim 9
Dependent Claim
129 words
