Definitions

  • ABSTRACT The specification discloses a mobile coke quenching apparatus accommodated to the control of air pollution.
  • the apparatus comprises two adjacent oppositely rotating hoppers between which a wedge-shaped bridge is tangentially disposed in centered alignment to an entrance doorway.
  • the end of the bridge furthest from the doorway has a nose inclined upward and flared plowlike symmetrically to both sides.
  • the entire coke oven charge being pushed is deposited on the bridge, moved toward the nose, and then forced away from the wedge-shaped bridge into the hoppers on either side by the plowlike action of the nose thereon.
  • Conjoint action of the nose and rotation of the hoppers causes pile-up of the coke charge in a circular ridge at the top surface of the coke in the hoppers sufficiently to contain the entire coke oven charge being pushed.
  • the coke oven charge is gravitationally deposited on the central area of rotary tables beneath the hoppers upon which it is quenched and across which it is impelled radially and removed at the peripheries thereof.
  • MOBILE ROTARY TYPE courruuons coke QUENCHEIR This invention relates to mobile apparatus for quenching coke and more particularly to such mobile apparatus having adjacent dual rotary hoppers into which the entire change of high temperature coke from an adjacent oven is equally distributed over a wedgeshaped bridge therebetween which is centered with respect to the entrance doorway.
  • the hoppers each deposit the coke by gravity action through a bottom outlet onto the central area of a corresponding rotary quenching table from which the coke is impelled radially outwardly and quenched and peripherally discharged.
  • I provide a mobile coke quenching apparatus of the type hereinafter referred to, having a pair of adjacent oppositely rotating hoppers separated by a wedgeshaped bridge having a plowlike nose portion by which the entering coke charge becomes substantially equally divided between the hoppers.
  • a pile-up of annular form at the top of each of the hoppers provides additional capacity to accommodate the entire oven charge being pushed.
  • a rotary quenching table beneath each hopper from which the coke is impelled radially and quenched and discharged as in prior quenching apparatus.
  • FIG. I is a longitudinal elevational view, partly in section
  • FIG. 2 is a plan view, with a fragment in section
  • FIG. 3' is a vertical sectional view, taken substantially on the line IIIlII of FIG. 2.
  • the embodiment of improved quenching apparatus there shown comprises a wheeled vehicle 10 operating on track rails 11 in parallel spaced relation to a battery of coke ovens 12 (see FIG. 3) with a wheeled coke guide 13 operating on track rails 14 interposed at an elevated position between the track rails 11 and the coke ovens 12.
  • Vehicle 10 comprises a plurality of pairs of wheeland-axle units 15 in longitudinally spaced relation supporting thereon a vertically rising structural framework 16 in which are a pair of adjacently disposed bins 17.
  • Each of the bins 17 comprises an upper essentially circular portion 18, fixedly secured to the structural framework 16 and having a closed ceiling or roof portion 19 to which ventilating ductwork such as at 20 may be connected through an opening therein.
  • a doorway structure 21 Access for entry of coke from the ovens 12 to the bins 17 on the quenching vehicle 10 is provided by a doorway structure 21, the doorway 22 of which is normally closed by a pair of oppositely swinging hinged doors 23 (see FIGS. 2 and 3) which are opened and closed by suitable power means, such as air or hydraulic operated cylinders (not shown).
  • the coke guide 13 may be provided with a suitably constructed tunnel enclosure indicated by the broken lines in FIG. 3, through which the coke charge traverses the intervening space between oven doorway 24 and doorway 22 on the quenching vehicle.
  • the smoke, fumes and particulate matter which emanates from the coke charge during the transfer to the quenching vehcile 10 may be substantially prevented from escaping to the atmosphere and be withdrawn and recovered, as through the ductwork opening out of each bin structure, by means such as a blower or fan 26 (FIG. 1) connecting with duct work 20, or other appropriate means not shown. All such apparatus for the purpose of eliminating air pollution is more fully described in the copending application of Faber et a1.
  • Each of the bins 17 further comprises, according to the invention, a lower portion or hopper 28 of essentially inverted conical shape, the circular top edge of which is supported in closely spaced relation to the bottom edge of the upper bin portion 18.
  • Each hopper 28 is supported for rotary travel on a vertical axis by means of a plurality of circumferentially spaced rollers 29 supported on the framework and which engage a horizontal circular track 30 on the outside wall of the hopper 28.
  • Each of the hoppers 28 is rotated by a motor 31, through a pinion 32 on the shaft of the motor, which pinion meshes with a circular rack 33 on the outside wall of the hopper.
  • the hoppers are rotated simultaneously at the same speed and preferably in opposite directions with respect to each other.
  • the peripheral areas of the hoppers adjacent their point of tangency move synchronously in the same direction away from doorway 22, as shown by the arrows in FIG. 2.
  • a wedge-shaped bridge member 35 is disposed tangentially between the hoppers and in substantially centered alignment to the doorway 22.
  • the bridge member 35 has a substantially uniform cross-section of inverted V-shape from a point just inside the doorway 22 to a point near the longitudinal center line of vehicle 10, after which the side surfaces flare outwardly and the apex or ridge of the member 35 rises steeply upward in a substantially straight line to form a plowlike nose 35a(FIG. 3).
  • the base of the bridge member 35 is approximately at the level of the top of the rotary hoppers 28 and the sloping side surfaces of the nose 35a and of the bridge member overhang the edge of the hoppers 28 at 50 and 51 (FIG. 2), and then merge respectively into the walls of the upper circular portion 18 of the bins 17.
  • the coke oven charge is deposited on the bridge member 35, it is pushed toward the plowlike nose 35awhich acts to force the coke to either side of the bridge member at the top surface of the coke fill in the hoppers 28.
  • the overhang of the upper edge of the hoppers 28 by the sloping side surfaces of the plowlike nose 35a and of the bridge member at 50 and 51 insures that as the coke is forced into the upper circular portion 18 of the bins, it does not contact the side walls of the circular portion.
  • coke dust and particles are directed away from the thin gap between the upper edge of the hoppers and the bottom edge of the stationary circular portions 18 to avoid their escape to the atmosphere outside the bin and the consequent pollution of the surrounding air.
  • the bridge member 35 also serves to divide the quantity of high temperature coke, which is deposited thereon through the doorway 22, in substantially equal proportions so that the two hoppers 28 are substantially equally and concurrently filled with high temperature coke.
  • a rotary table 38 Disposed in spaced relation below the outlet 36 at the bottom of each of the hoppers 28 and in substantially coaxial relation thereto is a rotary table 38.
  • Each table 38 is supported on a central bearing 39 and is driven by a motor (not shown) through a pinion meshing with a circular rack 40 on the bottom of the table.
  • a plurality of rabbles 41 are suspended over the annular peripheral area of each of the rotary tables, on a plurality of radially extending arms, the rabbles 41 being disposed at an angle to the radius and in overlapping relation whereby they effect radial movement of the coke charge toward the periphery of the table.
  • a plurality of spray nozzles 42 are arranged in circumferentially spaced ra' dial relation above the annular peripheral area of each of the rotary tables 38.
  • the nozzles 42 are connected to a manifold pipe 43 and by suitable valve control means (not shown) provide an appropriate quantity of quenching liquid, such as water, to quench the coke deposited on and progressing across the rotary table.
  • a conveyor 46 (FIG. 3) is provided adjacent the periphery of each of the rotary tables 38 onto which the rabbles 41 move the quenched coke charge via exit chutes or wharves 45, also in the manner described in US. Pat. No. 3,536,592.
  • hoods 44 communicate with ducts 20a through which the steam and pollutants are propelled by fan 26.
  • the quenching vehicle 10 is shifted on rails 11 to a position in which the entry doorway 22 thereof is in registry with the doorway 24 of the particular oven of the battery of ovens l2 desired to be discharged.
  • a conventional door opening and cleaning machine (not shown) is then moved on the tracks 14 to a position in front of the oven door 47, and, after lifting the oven door out of the oven doorway, proceeds to clean off the door flanges and doorway frame.
  • the door opening and cleaning machine is then shifted out of the way carrying the oven door with it, and the coke guide vehicle 13 is shifted thereafter to a position on tracks 14 between the oven door 47 and the doorway 22 of the quench vehicle 10. In this position, the floor surface of the coke guide vehicle 13 bridges the gap between the sill of the oven doorway 24 and the sill of the quenching vehicle doorway 22.
  • the coke guide vehicle 13 may be provided with a tunnel-like enclosure (not shown) which seals at its opposite ends on the oven wall or doorway and the doorway 22 of the quench ve hicle 10, to minimize emanation of fumes and gases from the coke charge as it is pushed, by conventional ram mechanism, from the oven chamber across the floor surface 25 of the coke guide vehicle into the doorway 22 of the quench vehicle 10. It will be understood that the doors 23 on the quench vehicle 10 are appropriately opened, as by remote control means (not shown), just prior to the operation of the ram which pushes the coke charge out of the oven compartment, across the coke guide floor 25, and into the open inlet doorway 22 of the quench vehicle.
  • the process above described of unloading an oven compartment may be repeated for successive oven compartments, after reclosing doors 23 on the quenching vehicle 10 and restoring the oven door 47 to its closed position in the oven doorway 24, by shifting the quenching vehicle 10 and coke guide 13 into corre sponding registry therewith.
