Definitions

  • a movable smoke hood is arranged above a coke receiving car and extends along the front of a battery of coke ovens.
  • a tubular coke guide forms a passageway for a coke mass ejected from a coke oven chamber. This guide is connected in a smoke-tight manner to a central upstanding portion of a smoke hood used to envelop the fall space wherein the coke mass passes into the coke receiving car.
  • the smoke hood is further made up of hood portions at each side of the central hood portion.
  • the hood has a roof connected to side walls which extend downwardly below upstanding side walls of the coke receiving car. End walls on the car project upwardly into a closely-spaced relation with the underside of the roof at each side of the central portion for minimizing infiltration of air into the smoke hood.
  • This invention relates to a smoke hood apparatus for connection in a smoke-tight manner to a guide grating receiving a coke mass ejected from a coke oven chamher.
  • the smoke hood is arranged for alignment with each coke chamber forming a battery of coke ovens for which purpose the hood is movably supported above a coke receiving car in front of the coke ovens.
  • Smoke hoods are movable either on a coke car or on a special track above the coke car. These hoods were constructed to span the discharge area and, in other instances, they were designed to include a closure for the area above coke quenching equipment. Usually, these hoods were provided with exhaust treating equipment in the form of gas scrubbing devices for the smoke developed upon the discharge of the coke mass from the oven. In another form, the exhaust equipment was connected to a col lector duct that extended along the battery of coke ovens to receive the smoke developed at different loca tions along the ovens.
  • a smoke hood apparatus comprising an upstanding central hood portion and having at each of two sides additional hood portions attached thereto, the upstanding central hood portion is designed to envelop a fall space wherein a coke mass passes from a coke guide into a coke receiving car, the hood portions at each side of the central portion having a length approximately equal to the length of the coke receiving car, and end walls on the car project upwardly into a closely-spaced relation with the underside of the roof for the hood side portions.
  • the present invention additionally provides a downwardly sloping coke transfer chute on the coke car for receiving coke passing through the fall space in the smoke hood.
  • the side walls for the coke receiving car project above the coke transfer of the chute and side walls of the smoke hood project downwardly below to the upper surface of the side walls of the coke car.
  • a coke discharge opening is formed in the side wall of the hood adjacent the coke oven to further define the fall space for coke passing into the coke car.
  • the ends of the smoke hood are open for the passage of the coke car from beneath the smoke hood.
  • the smoke hood according to the present invention is particularly characterized by the formation of small gaps between the hood and the coke receiving car such that very small amounts of infiltrating air pass into the space enveloped by the hood whereby the volume of gas to undergo dust removal and scrubbing is kept within reasonable limits.

  • a platform 24 extends along the discharge side of the coke ovens (FIG. 1) where it is supported below the oven chambers by supports 25.
  • the platform carries spaced-apart parallel rails 25A for wheels 26 which support a guide grating 27 for coke mass as it is displaced horizontally upon ejection from one of the coke oven chambers.
  • the guide grating actually consists of two parts 28A and 28B which can be moved with respect to each other in the longitudinal direction of the oven chamber.
  • Each coke receiving car 30 has a downwardly inclined chute 32 with a coke receiving surface 32A for the transfer of glowing coke into the coke receiving cars 30 from where, after quenching, the coke is discharged upon a ramp 18.
  • the coke receiving car includes a side wall 33 extending above the upper end of the chute 32 which is adjacent the coke oven and a side wall 34 at the opposite side of the car. These walls are joined at the ends of the coke receiving car by end walls 35 and 36 which extend in a vertical direction beyond the height of the side walls 33 and 34.
  • FIGS. 1-3 illustrate a smoke hood apparatus in the form of a unitary structure consisting of an upstanding central hood portion 37 and side hood portions 38 and 39 connected at opposite sides to the portion 37 so as to define a smoke hood 40 extending in a horizontal direction along a number of coke oven chambers.
  • the upstanding central hood portion 37 projects above the coke guide grating 27 and this hood portion is somewhat wider than the coke mass guide grating so that it can be connected in a smoke-tight manner by a detachable coupling ll3.
  • the smoke hood is supported at spaced locations along its length by wheels 41A and 418.
  • the wheels 41A engage rails carried by the platform 24 and the wheels 41B engage rails 42 which are carried by supports 17 arranged at the side of the smoke hood opposite the platform 24. As shown in FIG. 1, the supports 17 also carry a collector duct R for the exhaust of smoke from the smoke hood 40.
  • the portions 37, 38 and 39 of the smoke hood each include a roof plate 52 defining the upper surface of the hood which is joined to a side wall 43 facing the coke oven.
  • the wall 43 passes downwardly to enclose the upper edge of wall 33.
  • the hood is designed to conform to the profile of the coke receiving car as best shown in FIG. 4.
  • the wall 43 lies above the chute 32 and is bent to extend in a horizontal direction toward the coke oven.
  • a vertical wall 44 extends in a closely-spaced relation with and below the side wall 33 of the coke receiving car.
  • the walls 43 and 44 extend along the entire length of the hood with the exception that at the central portion of the hood, the walls 43 and 44 define an opening 12 to the fall space enclosed by the hood for the passage of coke into the coke receiving car.
  • a side wall 45 forms the side of the hood remote to the coke ovens.
  • the wall 43 extends downwardly beyond and encloses the top surface of the wall 34 of the coke car.
  • the upstanding central portion 37 of the smoke hood is attached to a pipe 14 for the delivery of smoke and fume collected within the hood to the collector duct and connected thereto by means of an intermediate connection piece 16 (FIG. 1).
  • FIG. 3 illustrates the position of thecoke receiving car for the initial loading of coke into the car.
  • the coke As the coke is ejected from the coke chamber, it passes through the guide grating and thence into the smoke hood where it passes through the entrance opening 12 to the fall space that is specifically enveloped by the hood portion 37.
  • the coke passes into the coke receiving car while it is moved in the direction of the arrow 11. It will thus be observed that the end wall 36 of the coke car is placed nearest the point where the upstanding central portion 37 joins the hood portion 39.
