The disclosure relates to a base for supporting hollow cylindrical and circular in cross section collector electrodes for an electrostatic precipitator. The base comprises a central portion and is generally circular; a plurality of arcuate venturi and collector trough assemblies which are generally circular and which intersect radially disposed drain troughs; said venturi and collector trough assemblies being concentric with said center portion of said base and drain troughs extending radially outward from said center portion; a circular wall structure secured to outer ends of said drain troughs; fixture means for securing said collector electrodes on said drain troughs; uppermost portions of said drain troughs and said venturi and collector troughs being substantially flush with each other and said venturi and collector trough assemblies disposed on a common plane to provide for uniform laminar flow relative to the collector electrodes.

Electrode supporting base for electrostatic precipitators

The disclosure relates to collector electrodes for electrostatic precipitators and particularly to generally annular in cross section hollow cylindrical collector electrodes having a pair of spaced concentric wall structures with a filler means disposed therebetween, the filler means being a lightweight filler means and hermetically sealed in and between said wall structures. The disclosure also relates to fixture means in the lower ends of the hollow cylindrical collector electrodes, the fixture means comprising internally screw threaded openings in blocks secured or fixed to the lower ends of the collector electrode so as to provide for the use of screw threaded bolts for securing the lower ends of the collector electrode structures in juxtaposition. The disclosure also relates to modifications and/or various species of the lightweight filler means between the inner and outer walls of the collector electrode.

Collector electrodes for electrostatic precipitators

A flow preconditioner for an electrostatic precipitator which removes particulate matter from a stream of polluted gas immediately after it passes through a tangential inlet at the lower end of a vertical cylindrical housing and straightens and divides the stream into laminations parallel to the axis of the housing. It comprises an annular ledge or choke ring extending inwardly from said housing above the inlet and an assembly of vanes above said ledge extending radially from the axis of the housing and angularly spaced apart. Each of said vanes has a flow receiving edge directed toward said inlet, a curved portion extending upwardly and away from said inlet, and a flat portion extending upwardly from said curved portion in a plane parallel to the housing axis. The curved portion of each vane defines a trough having a camber which gradually decreases along its span from the outer end of the vane towards the axis of the housing, together with means to vary the centrifugal flow distribution relative to the housing to render the preconditioner adjustable for various flow capacities.

Flow preconditioner for electrostatic precipitator

The disclosure relates to a method for producing hollow cylindrical structures, and more particularly for producing hollow cylindrical structures which may serve as collector electrodes for electrostatic precipitators; the method comprising the forming of a first resin and fiberous structural layer on a rotating mandrel, then applying a foam structure forming resin on the first structural layer, then permitting the foam structure to cure into a structural condition, then lathe turning the periphery of the foam structure to a uniform annular cylindrical surface, then applying a second layer of resin and fiberous material to form an external structural layer and then finishing the exterior of the last mentioned structural layer to a uniform annular shaped surface, and finally coating the last mentioned surface with a water resistent resinous material and then removing the glossy surface from said last mentioned material to prevent surface tension of water from separating flow on said last mentioned surface; the disclosure also relating to detailed instruction of the aforementioned fiberous structural layers.

Method for producing hollow cylindrical structures

The disclosure relates to an insulator means for electrostatic precipitators wherein a column is centrally supported on a base structure above which a plurality of concentric generally cylindrical and circular in cross section discharge electrodes are electrically coupled to and suspended from radially disposed arms supported on said column; said discharge electrodes being adapted to operate between respectively circular in cross section collector electrodes; said arms being supported on said column by means of a hollow insulator having a bore therethrough and a high voltage conductor extends upwardly through said bore of said hollow insulator; said conductor being electrically coupled with said arms; and grease like dielectric material packed in said bore of said insulator and surrounding said conductor therein; and a sheath surrounding said conductor and disposed between said conductor and said grease like dielectric material; the disclosure also relating to means for mechanically coupling said insulator to said arms and said column. The disclosure also relates to novel means for providing an aerodynamic protective curtain around the insulator means so as to prevent the collection of conductive material thereon.

The disclosure also relating to fixture means in the lower ends of the hollow cylindrical collector electrodes, the fixture means comprising internally screw threaded openings in blocks secured or fixed to the lower ends of the collector electrode so as to provide for the use of screw threaded bolts for securing the lower ends of the collector electrode structures in juxtaposition. The disclosure also relating to modifications and/or various species of the lightweight filler means between the inner and outer walls of the collector electrode. Additionally, the disclosure relating to a novel water distributor means carried at the upper edge of the collector electrode for distributing water uniformly over the inner and outer walls of the collector electrode. The collector electrode being formed in a plurality of arcuate sections and secured to shoulder structure of the collector electrode body by means of screw threaded bolts. The disclosure also relating to a method for producing collector electrodes for electrostatic precipitators.
