Definitions

  • vent means includes a stack having a gas inlet end that is enclosed within a g V V gas plenum chamber having a water sprinkling system therein for providing a curtain of water around the [56] Refierences canted inlet end for washing the gas as it enters the stack,
  • a coke oven which is part This invention relates to apparatus for discharging of a plurality of similar ovens in a battery of by-product and quenching coke from by-product coke ovens, and more particularly it pertains to a system for sprinkling water on the coke and on smoke and dust generated thereby for minimizing air pollution.
  • the apparatus includes means for minimizing the amount of smoke and dust incurred during the collapse of the coke mass as it is discharged from the oven and falls into the quench car as well as means for washing all traces of smoke, noxious fumes, and dust from the air as it is discharged from the smokeconfining hood.
  • the advantage of the apparatus of the present invention is that not only is the air cleaned to remove noxious fumes and dust before it is discharged from the hood, but the amount of dust and smoke is minimized due to themanner in which the coke is conveyed from the oven to the quench car; that is, with a minimum of precipitous collapse immediately upon discharge from the oven chamber, a more gradual breakdown of the cake-like mass of coke occurs, whereby smoke and dust are minimized.
  • FIG. I is an elevational view, partly in section, of the apparatus of the present invention.
  • FIG. 2 is a vertical sectional view taken on the line II-II of FIG. I and showing coke being discharged from an oven and into a quench car;
  • FIG. 3 is a sectional view, taken on the line III-III of FIG. 2.
  • a so-called pusher or discharge ram I2 is used for pushing a cakelike mass of coke I4 from the oven Ill through a coke guide I6 and into a quench car 16, the latter of which is enclosed within an elongated hood 20 (FIG. I) which is slightly longer than the quench car Iii.
  • the coke guide I6 is mounted on a carriage 22 which travels along a track 24 on a platform 26 in front of a battery of coke ovens 28 (FIG. I).
  • the coke guide I6 is a tubular member through which the coke I4 passes and is preferably rectangular in cross section.
  • the end of the coke guide 116 adjacent to the front wall of the battery 26 of coke ovens has suitable means for engaging the frame of the oven in a substantially air-tight manner.
  • the coke guide I6 includes a pair of telescoping tubular sections 30 and 32, the latter of which after being brought into proper alignment with the oven It) to be discharged by travel of the carriage 22 is moved to the right (as viewed in FIG. 2) and brought into substantial airtight contact with the frame of the oven.
  • the location of the telescoping section 32 in contact with the oven I0 is shown more particularly at 33 in FIG. 3.
  • the coke guide I6 may be an integral part of the hood 20 or the coke guide may be a vehicle separate therefrom.
  • the telescoping section 36 is attached to and extends outwardly from a side wall 34 of the hood in which wall an opening 36 (FIG. 2) is provided for communication between the interior of the coke guide and the hood.
  • the floor of the interior of the coke guide I6 includes a plate-type conveyor belt 38 which extends between and around driven rollers 40, the upper portion of which belt travels to the left as shown in FIG. 2 for moving the coke I4 through the sections 36 and 32 and onto the sloping bottom 42 of the quench car I8.
  • the roof of the section 36 slopes downwardly at 44 to minimize the space within the chamber formed by the coke guide I6.
  • a pendulum flap 46 suspends from the top of the opening 36.
  • the coke I4 collapses from its higher level within the oven Id due to the action of the plate conveyor belt 36.
  • the flap 46 serves as a baffle for the coke and limits the smoke, steam, and dust which develop within the hood 20 from flowing into the chamber of the coke guide.
  • the quench car I8 having wheels 48 is mounted on tracks 50 which tracks are parallel to the battery of ovens 28 and which are located at a level below that of the tracks 24. Accordingly, as it is discharged by the pusher or ram I2 the coke I4 is moved through the coke guide I6 and on the plate conveyor belt 33% into the quench car I8, where a water 52 is sprayed from nozzles 54.
  • the hood 26 includes spaced vertical side walls 56 and 34 as well as a top wall 66 with sloping end portions 62 and 64 as well as opposite end walls 66 and 66.
  • the walls 34, 56, -66 form a hood chamber III in which smoke, fumes, dust and steam, arising from the sprayed coke I4, is confined and prevented from escaping into the surrounding atmosphere until after it has been cleaned.
  • the lower edge of the side wall 56 is supported on spaced wheels '72 which travel on a rail 74 which is mounted on a wall 76.
  • the side wall 34 is supported in one of two ways.
  • the coke guide 16 may be an integral part of the hood 20 in which case the telescoping section 30 is attached to the side wall 34 around the opening 36, and the right side of the hood 20 (FIG. 2) is attached to the carriage 22 by spaced connecting members, such as reinforcing I-beams 78, in which case a portion of the weight of the hood is borne by the carriage 22 which has wheels 80 which are supported by the tracks 24.
  • the coke guide 16 is a vehicle separate from the hood, alternate support means are required.
  • the right side wall 34 is supported on wheels 80 that travel on a track 82 in a manner similar to the wheels 72 and track 74 at the lower end of the left side wall 56.
  • the wheels 80, the track 82 and a support wall 84 are shown in broken lines as alternative support means for the hood.
  • the telescoping section 30 of the coke guide 16 is separate from the side wall 34, but is sufficiently proximate thereto as to provide a snug, substantially air-tight connection between the interior of the coke guide section 30 and, the opening 36 in the side wall.
  • vent means are provided for the gases within the hood chamber 70 which means include a stack 86, a centrifugal separator or fan 88, a boxlike plenum chamber 90, and sprinkling means 92 within the chamber for spraying a water curtain 94 for washing the gas before it enters the stack 86.
  • the lower open end 96 of the stack 86 is disposed within the plenum chamber 90 and spaced above a bottom wall 98, the periphery of which includes a trough 100 for gathering water from the water curtain 94 during operation of the flue.
  • two perforated partitions 102 are provided to facilitate the filtering of dust from the gases in the hood which gases enter the plenum chamber 90.
  • a suction created in the plenum chamber 90 by the fan 88 pulls the smoke-filled air through the water curtain 94 and the air is cleaned before it enters the stack 86.
  • a drain 104 extends from the trough 100 to a trough 106 at the lower end of the support wall 76 which trough 106 extends continuously along the path of travel of the hood 20.
  • Means for supplying water to the sprinkling means 92 as well as the nozzles 54 include supply pipes 108 and 110, as well as a pump 112 and the lower end of the conduit 108 extends into a water trough 114 which is likewise coextensive with the path of travel of the hood 20.
  • the smoke and dust problem which is ordinarily a concomitant part of the coke discharge and quenching operation is substantially eliminated.
  • the extent of sprinkling of the coke onto the hood is usually sufficient only to the point at which no smoke forms and no violent combustion occurs, sufficient quenching may occur to completely quench the mass of coke under the hood.
  • the total time for quenching one discharge of coke from an oven is usually three minutes. However, intermittent or partial quenching may be used where more accurate dosing of the total water quantity is used.
  • the device provides a conveyor belt by which the cake-like mass of coke as it issues from the oven is not only conveyed more expediently to the quench car but is broken up into smaller pieces more rapidly due to its greater speed of movement, such as three or four times that of the pusher or ram 12, and thereby induces a collapse of the coke within the coke guide as it falls into the quench car.
  • the coke drops over a more gradual slope into the quench car and thereby creates less smoke and dust.
  • the combustion of the coke is minimal and theres a corresponding reduction in smoke and noxious fumes.
  • the resulting smoke and fumes are washed from the air as it passes through the water curtain and flue.
  • Apparatus for preventing air pollution during discharge of coke from coke ovens disposed side-by-side in a row comprising a carriage movable along the row of ovens, a quench car movable along a path of travel parallel to and on the side of the carriage opposite that of the row of ovens and on a level below that of the carriage, tubular guide means on the carriage and alignable selectively with each oven for receiving coke from an oven and guiding the coke to the quench car, conveyor belt means in the bottom wall of said tubular guide means for moving coke through the guide means, a hood above the quench car and having a side wall on opposite sides and a top wall above the quench car, track means on opposite sides of the quench car on which the hood is rollably mounted parallel to the path of travel of the quench car, the side wall facing the ovens having an opening communicative with the tubular guide means, means within the hood for spraying water onto the coke in the quench car, and flue means on the top wall for venting
  • the flue'means includes a stack, and means for providing a curtain of water around the inlet end of the stack for washing smoke-laden air leaving the interior of the hood through the stack.
  • gas suction means are in the stack for pulling air out of the hood.
