Abstract

1280516 Decontaminating fluids RESOURCE CONTROL INC 8 Oct 1969 [8 Oct 1968] 49418/69 Heading B2J [Also in Division F1] The combustion products of engines, incinerators, industrial furnaces &c are treated to remove both gaseous and particulate contaminants by subjection to electromagnetic radiation from a light source as at 30 having an output in the spectral range of from 1500Š to 7200Š the light source 30 being disposed in the area of a high voltage field from spaced anode-cathode electrodes 24, 20 which are connected to a high voltage source which produces a dark current flow or glow discharge condition between the electrodes and is controlled to prevent disruptive corona discharge and arc-over between the electrodes. Gaseous contaminants such as the oxides of N, S or C are removed as a result of photoionisation caused by UV light. The applied voltage may be controlled in a closed loop system according to the measured conductivity or resistivity of the incoming gas. Effluent of substantially constant contaminant content may be produced. A grid 40 may carry a negative potential for control purposes. The anode 24 is of open wire mesh or grid construction and is preferably grounded. The cathode 20 may comprise metal plates 50 (Fig. 5) supported on a tubular post 56 inside which is mounted an electrostatic generator which employs a belt 62 driven by a motor 66, a charging screen being positioned adjacent the belt surface. The cathode surfaces may be enclosed in a flexible plastic bag 74 which can be temporarily inflated to effect dislodgement of the collected particles. Alternatively, deposited particles may be removed by wiping or brushing (by hand in small installations), or by vibrations preferably at the resonant frequency of the cathode.
