Electric dust collector

Claim 2

An electrostatic precipitator overlying a vent hole within the roof of a factory building, said precipitator comprising: an open ended outer shell extending upwardly from said roof and surrounding said vent hole for effecting flow of air from said building through said shell by the thermal buoyancy of said air, a plurality of laterally spaced, vertical dust collecting electrodes within said shell, a series of vertical, discharging electrodes corresponding to said collecting electrodes arranged at regular intervals, and interleaved between said collecting electrodes and being connected to an electric power supply, said dust collecting electrodes being in planar sheet form and formed of light weight material, and sets of vertically spaced louvers positioned beneath said electrodes with said louvers being inclined outwardly and downwardly toward respective side walls of said shell relative to the center line of the precipitator in order to prevent the washing water from flowing into the work shop through the vent hole.

Claim 3

An electrostatic precipitator overlying a vent hole within the roof of a factory building, said precipitator comprising: an open ended outer shell extending upwardly from said roof and surrounding said vent hole for effecting flow of air from said building through said shell by the thermal buoyancy of Said air, a plurality of laterally spaced, vertical dust collecting electrodes within said shell, a series of vertical, discharging electrodes corresponding to said collecting electrodes arranged at regular intervals, and interleaved between said collecting electrodes and being connected to an electric power supply, said dust collecting electrodes being in planar sheet form and formed of light weight material, said collecting electrodes being formed of synthetic resin sheets having carbonaceous conductive material at least on the surfaces thereof, and sets of vertically spaced louvers beneath said electrodes to respective sides thereof, with said louvers being inclined outwardly and downwardly towards opposed sidewalls of said shell relative to the center line of said precipitator.

Claim 4

An electrostatic precipitator overlying a vent hole within the roof of a factory building, said precipitator comprising: an open ended outer shell extending upwardly from said roof and surrounding said vent hole for effecting flow of air from said building through said shell by the thermal buoyancy of Said air, a plurality of laterally spaced, vertical dust collecting electrodes within said shell, a series of vertical, discharging electrodes corresponding to said collecting electrodes arranged at regular intervals, and interleaved between said collecting electrodes and being connected to an electric power supply, said dust collecting electrodes being in planar sheet form and formed of light weight material, said collecting electrodes being formed of synthetic resin sheets having carbonaceous conductive material at least on the surfaces thereof, and sets of vertically spaced louvers beneath said electrodes to respective sides thereof, with said louvers being inclined outwardly and downwardly towards opposed sidewalls of said shell relative to the center line of said precipitator.

Claim 5

An electrostatic precipitator overlying a vent hole within the roof of a factory building, said precipitator comprising: an open ended outer shell extending upwardly from said roof and surrounding said vent hole for effecting flow of air from said building interior through said shell by the thermal buoyancy of said air, a plurality of laterally spaced, vertical dust collecting electrodes within said shell, a series of vertical, discharging electrodes corresponding to said collecting electrodes arranged at regular intervals, and interleaved between said collecting electrodes and being connected to an electric power supply, said dust collecting electrodes being in planar sheet form and formed of synthetic resin having carbonaceous conductive material at least on the surfaces thereof, a water supply positioned centrally within said shell and beneath said electrodes, and sets of vertically spaced louvers positioned within said shell beneath said water spray, with said louvers being inclined outwardly and downwardly toward opposed sidewalls of said shell, and collector means on the inner periphery of the shell bottom for removing water dripping from said louvers and the dust entrained therein.

Claim 6

An electrostatic precipitator overlying a vent hole within the roof of a factory building, said precipitator comprising: an open ended outer shell extending upwardly from said roof and surrounding said vent hole for effecting flow of air from said building interior through said shell by the thermal buoyancy of said air, a plurality of laterally spaced, vertical dust collecting electrodes within said shell, a series of vertical, discharging electrodes corresponding to said collecting electrodes arranged at regular intervals, and interleaved between said collecting electrodes and being connected to an electric power supply, said dust collecting electrodes being in planar sheet form and formed of synthetic resin having carbonaceous conductive material at least on the surfaces thereof, a water supply positioned centrally within said shell and beneath said electrodes, and sets of vertically spaced louvers positioned within said shell beneath said water spray, with said louvers being inclined outwardly and downwardly toward opposed sidewalls of said shell, and collector means on the inner periphery of the shell bottom for removing water dripping from said louvers and the dust entrained therein.
