Definitions

  • ABSTRACT A process for quenching coke from coke ovens by independent spray pipes arranged parallel to each other to extend along the length of a coke transfer car while located beneath the chimney of a quenching tower.
  • the coke transfer car has an inclined support floor to provide a progressively decreasing depth of coke transverse to the car The water discharged by each [5!] Int.
  • This invention relates to a process for quenching hot coke that has been spread out on a quenching car after discharge from a coke oven. More particularly. the present invention relates to quenching the hot coke through the controlled use of a water sprinkler system installed beneath the chimney of a quenching tower.
  • the steam produced during quenching ofcoke has an extremely powerful draft or uplift which is magnified further by the chimney effect of a quenching tower.
  • the quenching steam emerges from the upper end of the quenching tower. it takes the form of a large white cloud which then becomes identifiable and associated with the coke quenching process.
  • the cloud of quenching steam is visible from great distances and it is symbolic of the presence of a battery of coke ovens.
  • the quenching steam manifests itself as a white steam cloud. it does nevertheless. contain a great number of solid particles which have been carried in the cloud upwardly from the coke. In addition to the solid particles. the cloud includes poisonous components which. among other origins. stem from the sulfur content of the coke.
  • the invention achieves a lowering of the draft inherently associated with the quenching steam and. therefore, it is easier to bind or restrain the solid materials contained in the quenching steam to prevent their discharge into the atmosphere.
  • This binding or restraining of the solid material in the quenching steam is carried out by way of the use ofa water sprinkling system and. ifappropriate. by way of installations used to cause the sudden expansion of the steam.
  • a process for quenching hot coke from coke ovens by a water sprinkling system arranged above a container bearing hot coke while located beneath the chimney of a quenching tower includes the steps of sprinkling the hot coke at a first preselected water dis charge rate throughout an initial time segment which is a fractional part of the time duration of a quenching process. and thereafter sprinkling the hot coke throughout the remaining time for the quenching process at a final water discharge rate which is essentially and materially greater than the first preselected water discharge rate.
  • the invention is based upon the following consider ations and assumptions. About 25 percent of the total amount of water introduced in connection with the quenching of coke will vaporize whereas the remaining 75 percent of this water will run off. The run-off portion of water is conducted to a settling or clearing tank. The quenching process takes place over an extended period of time. During the first few seconds of time. almost all of the quenching water will vaporize. The vaporization of water then diminishes rapidly and during the last phases of the quenching process. the water serves only as a coolant for the partially cooled coke.
  • the present invention takes advantage of the foregoing considerations and phenomena by providing that the amount of water added per unit oftime consists of only a fraction of the amount of water that is customarily added at the start of the quenching process.
  • the invention provides that thereafter an additional amount of water per unit of time is gradually increased up to the usual water discharge rate which remains unchanged until the end ofthe quenching process.
  • the amount of quenching water that vaporizes is considerably lessened during the initial portion of the quenching process.
  • only jets or impulses of steam occur at greatly decreased velocity and it is thereby possible to control the steam by way of sprinkling and deflector members mounted in the quenching tower. thus rendering it essentially easier and more effective to remove the harmful materials entrained in the quenching steam. This will practically eliminate burdens inflicted by the quenching steam upon the areas surrounding a quenching tower.
  • the coke is spread out on an inclined surface which may typically take the form of an inclined floor of a quenching car.
  • the invention contemplates the use of a suitable water system in which the discharge of coolant water is effected by way of a plurality of pipes arranged in a parallel. spaced-apart location so as to extend along the length of the quenching car. In this form of the process.
  • the water discharge pipe below which the greatest depth of coal is located is open first to discharge water onto the underlying coke and then successively one pipe after another is controlled to discharge water onto the hot coke underlying these pipes so that the successive application of water occurs in the direction of a decreasing coke bed height.
  • FIG. 1 illustrates a vertical section through a quenching installation and includes the lower portion of a quenching tower
  • FIG. 2 is a sectional view taken along line lI-II of FIG. I and illustrates in greater detail one form of water distribution system to carry out the process of the present invention
  • FIG. 3 is a composite graph illustrating the features and advantages of the present invention.
  • FIG. I there is illustrated a quenching tower having vertical walls It].
  • Rails ll carry a wheeled-support frame 12 ofa quenching car for movement into and out of the quenching tower.
  • the quenching car has an inclined floor 13 for supporting hot coke 14 at a non uniform depth transversely of the car.
  • the coke has a maximum depth while at its opposite longitudinal side.
  • the coke has a minimum depth.
  • Elongated water pipes 15, l6, l7 and 18 are arranged in a parallel, spaced-apart relation at a location above the quenching car and extend along the length of the car. These horizontal pipes are connected by way ofshut-off valves 19a. 19b. 19c. and 19d. respectively.
  • sprinkling nozzles 22 are provided along the length of each horizontal pipe l5. 16, I7 and 18.
  • Reference numeral 23 identifies the space above the pipes forming the water sprinkling system as just decribed.
  • Components 24 are located within the upper portion of the quenching tower and may take the form of closure or deflector plates arranged in such a manner to deflect and partially obstruct the rising currents of air and steam in the tower. The components 24 may be made adjustable to control the passage of the rising currents of steam and air. Above the components 24. there is located a spray pipe 241: for directing a plurality of water sprays onto the components 24.
  • Gutters 25 collect the water that drains off in the tower after sprinkling.
  • valve 19a is opened. thus feeding water to pipe for spraying the coke lying thereunder.
  • valve I9u Approximately ten seconds after valve I9u is opened.
  • valve [9b is opened. thus feeding water to pipe 16 to spray the coke thereunder.
  • valve 19c is opened to feed water to pipe 17 for spraying the coke located thereunder.
  • valve 19:! is opened to feed water to pipe I8 to spray the coke thereunder.
  • valves I'M-I911 are opened in succession at ten-second intervals, whereby at the end of a thirty-second time lapse. All of the valves will be open and spraying water through their associated pipes onto the coke.
  • the valves may be opened manually. however solenoid-operated valves may be employed for operation in the above-described manner from a re- LII mote position. Timed operation of these valves may be further enhanced by providing a controller to sequentially open the valves in an automatic manner.
  • FIG. 3 illustrates the timing ofthe quenching process.
  • the abscissa of the graph shown in FIG. 3 represents time marked off in seconds and the ordinate 0f the graph in FIG. 3 represents kilograms of quenching water discharged per second per ton of coal.
  • the final water discharge rate per ton of coal is assumed to be 20 kilograms.
  • the process according to the present invention provides that initially the quenching of coke is effected with only one-fourth of the amount of water heretofore employed at the start of the quenching process.
  • the water discharge rate is then increased in increments at IO-second intervals by 5 kilograms until the full water discharge rate has been reached requiring a total period of 30 seconds to achieve such a full discharge rate.
  • reference numerals l-4 indicate water discharge levels that increase after successive time inter vals.
  • curve A relates to the heretofore customary process for quenching coke.
  • Curve A divides the rectangular space of the graph into two parts of which the portion above the graph line corresponds to the portion of quenching water that is re turned for collection by the gutters 25 (FIG. 1).
  • the area in the graph lying below curve A represents the amount of water that is vaporized according to the known quenching process. It is, therefore. evident that a substantial vaporization of water occurs within the first few seconds of quenching time but that the vaporization process diminishes very rapidly thereafter.
  • the draft which occurs with a great uplifting force in the quenching tower is generated initially within the rising quenching steam and therefore it is very difficult to effect cleaning of the quenching steam to remove harmful materials by using apparatus located in the upper portion of the quenching tower.
  • the graph of FIG. 3 further includes curve B in the form of a broken line which also separates the graph into two areas.
  • the area below the curve B represents the vaporized portion of the quenching water.
  • the return portion of the water is delineated by the area above graph line B which lies to the right of the dotdash line identified by reference numerals 1-4. From the representations of FIG. 3, it is obvious that the greatest amount of steam produced in regard to curve B is considerably lower than that amount of steam which is produced as represented by curve A at the same time interval.
  • the input of jets or bursts of steam into the quenching tower has been moderated.
  • the spray pipe 24a and closure or deflector plates 24 are far more effective to remove pollutants from the rising current oi steam in the quenching tower.
