Description

  The present invention relates to a wet fire extinguishing method and wet fire extinguishing equipment for red hot coke discharged from a coke oven.

  Coke is produced by carbonizing coal in a coke oven. At this time, in order to prevent the transportation equipment such as the belt conveyor from burning out when the coke discharged from the coke oven (red hot coke) is transported to a blast furnace, a large amount of water is sprinkled on the red hot coke. The temperature is cooled to a temperature that can be transported by a belt conveyor or the like (for example, 250 ° C. or lower). This fire extinguishing by watering is called wet fire extinguishing.

  Generally, red hot coke from a coke oven is mounted on a fire extinguisher wagon, the fire extinguisher freight car is moved to a fire extinguisher, and a large amount of water (fire extinguishing water) is added to the red hot coke installed in the fire extinguisher wagon inside the fire extinguisher. Wet fire extinguishing red hot coke by spraying water (see, for example, Patent Document 1).

Usually, a portion (range E in FIG. 2) from the lower end Q point to the height position R point of about 1/3 of the entire height is the gate 15 in the entire height of the lower end side plate 14. When the gate 15 is opened, the red hot coke 1 slides along the inclination of the bottom plate 12 and is discharged from the gate 15 to the outside.

  Here, when the red hot coke lump 1 is normally mounted on the coke mounting box 11, the red hot coke lump 1 is loaded over the entire bottom plate 12 from the inclined upper end P point to the inclined lower end Q point of the bottom plate 12. Instead, the red hot coke lump 1 is loaded up to a predetermined height position of the bottom plate 12. That is, stacking is performed so that the upper surface of the red hot coke lump 1 is positioned at a position C on the bottom plate 12 that is a predetermined distance below the inclined upper end P point of the bottom plate 12.

  On the other hand, in the fire extinguisher, in order to extinguish the red hot coke lump 1 mounted on the fire extinguishing freight car 10N, a watering device 20N is installed so as to be positioned above the fire extinguishing freight car 10N. The watering device 20N branches from the head water tank 21 in which fire extinguishing water is stored, a main watering pipe 22 extending from the head tank 21, a watering valve 23 installed in the main watering pipe 22, and the main watering pipe 22.
