摘要： The specification discloses a film-shaped dust collecting electrode and an electric dust collecting apparatus having a stack of the electrodes. The electrode includes a conductive film painted onto a central area of a surface of a rectangular insulative film. A terminal base and a terminal conductor of a tongue shape extend from one shorter edge of the insulative film. A plurality of spacer protrusions are provided at spaced intervals along the opposite longer edges of the insulative film. The spacer protrusions along the opposite longer edges are staggered from one another with the conductive film intervening therebetween. Hollow frustoconical coupling protrusions are disposed symmetrically about the intersection of the two diagonal lines of the insulative film. The height of the coupling protrusions is higher than that of the spacer protrusions. In the dust-collecting apparatus, a plurality of the electrodes is stacked with the direction of terminal conductors alternately reversed. The coupling protrusions prevent relative displacement between adjacent electrodes.

摘要： A particle charging apparatus (Boxer-Charger) is constructed by disposing electrode assemblies each consisting of corona discharge electrodes and excitation electrodes, in parallel to each other with a charging space interposed therebetween. An a.c. voltage is applied between the corona discharge electrodes in the respective assemblies to establish a main electric field in the charging space. When the a.c. main voltage has entered a half cycle of particular polarity such as, for example, negative polarity, an excitation high frequency voltage including fast-rising pulses having a pulse duration time of 1 ns-1 ms is applied between the corona discharge electrodes and the excitation electrodes in the assembly to generate a creeping streamer on the corona electrode surface and thereby form a two-dimensional plasma source. Only negative ions are drawn out from this ion source by the action of the main electric field, and these negative ions will travel through the charging space towards the assembly on the opposite side. In the next half cycle, the assembly on the opposite side emits negative ions in the opposite direction. Accordingly, dust particles passing through the charging space are charged as they are bombarded by the negative ions alternately from the opposite directions. If the phases of the main voltage and the excitation voltage are shifted by one-half cycle relative to each other, then charging by positive ions can be achieved.

摘要： An improved pulse-charging type electric dust collecting apparatus is described herein, which comprises dust collecting electrodes and high corona-starting-voltage discharge electrodes disposed in opposed relationship to the dust collecting electrodes, both electrodes being arranged within a main body casing having a gas inlet, gas outlet and a dust exhaust port. An adjustable D.C. high voltage power source establishes a principal electric field between the electrodes, and an adjustable varying voltage power source having an adjustable magnitude, waveform width and repetition period is connected in series to the adjustable D.C. high voltage power source. After having intensely charged dust particles floating in a dust-containing gas introduced between the respective electrodes through the gas inlet by bombardment with the ion current under the high principal electric field, the dust particles are subjected to strong Coulomb's forces to be effectively adhered onto the dust collecting electrodes. Collected dust is exhausted to the exterior, while cleaned gas is discharged through the gas outlet. By adjusting the average value of the ion current independently of the principal electric field to inhibit inverse ionization by controlling the magnitude, waveform width and repetition period of the adjustable varying voltage, dust can be efficiently collected without inverse ionization even when it has an extremely high resistance.
