Abstract: 1, 049, 470. Gas scrubber; electrostatic precipitators. ELECTRONATOM CORPORATION. Oct 9, 1964, No. 41372/64. Headings B1R and B2J. In apparatus for removing dust from a gas wherein a web-type electrostatic precipitator is disposed above a gas scrubber, the gas is introduced into the scrubber through a tangentially arranged inlet 27, sprayed with washing liquid therein and passed through at least two set of vanes 34 and 35 which convert the turbulent flow of the scrubbed gas into a linear flow before it enters the electrostatic precipitator. Washing liquid is sprayed into the gas through sprays 28 and at 29, a baffle 32 serving to deflect scrubbing liquid into an annular gap surrounding the baffle. The electrostatic precipatator has concentric inner and outer collector tubes (Fig. 10 not shown) defining between them an annular flow passage which contains a discharge electrode or (as shown) an array of such electrodes, the surfaces of the flow passage being irrigated with liquid from distributers at the upper ends of the concentric tubes. The discharge electrode or electrodes may be supported by insulated posts (Fig. 11 not shown) and the voltage may be applied to the electrode or electrodes through one of the posts. Openings connected to atmosphere and adjacent the posts may be provided whereby the flow of gas through the apparatus induces a flow of air through the openings for scavenging deposits from the posts. Similar air currents may be directed on to the structure supporting an annular liquid distributer for the outer concentric tube which is secured thereto.
