JPS5929629B2 - Smokeless treatment method for fallen coke - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for smokeless treatment of fallen coke.

The fallen coke is what falls onto the service platform around the kiln mouth when the furnace lid detacher of the guide car detaches from the furnace lid of the carbonization chamber during the kiln unloading process.

Such fallen coke is scraped up and disposed of appropriately, but one way of disposing of it is to collect it in a hopper attached to a guide car and then drop it into a receiving tank on a fire extinguishing train. There are ways to deal with it.

By the way, the above method is easy to treat and is practical, but when the fallen coke is dropped onto the red-hot coke, the tar and uncarbonized coal in the fallen coke smolder and yellow smoke is generated. It has the disadvantage of causing environmental problems.

The present invention solves the above-mentioned drawbacks and provides a smokeless treatment method for fallen coke. Then, a fire extinguishing train advances toward the fire tower from the rear end of the receiving tank to extinguish the fire, and a coke guide car advances in the opposite direction to the direction of travel of the fire extinguishing train. In a coke oven where preparation work for unloading the kiln is carried out sequentially, crushed coke is collected into a hopper attached to a coke guide car, and the crushed coke accumulated in the hopper is transferred to a receiving tank of a fire extinguishing train. When introducing the drop, the hopper is placed in front of the guide grid located on the side in the direction of progress of the coke guide car's kiln discharge preparation work, of the two guide grids mounted on the coke guide car. , a method for smokeless processing of fallen coke, characterized in that the fallen coke dropped from the hopper into a receiving tank of a fire extinguishing train is covered with red-hot coke.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a schematic plan view showing the overall arrangement of the coke oven;
FIG. 2 is a schematic side view showing the positional relationship between the coke guide car and the fire extinguishing train.

The red-hot coke pushed out of the carbonization chamber 2 by the extrusion ram of the extruder 1 passes between guide grids 4 and 4' mounted on the guide car 3, and is loaded into the receiving tank 6 of the firefighting train 5.

The red hot coke is loaded uniformly over the entire receiving tank 6 by moving the fire extinguishing train 5 in accordance with the amount of red hot coke discharged from between the guide grids 4 and 4'.

Therefore, in a normal coke oven, the fire extinguishing train 5 and the coke guide car 3 are moved in the following directions,
Work is underway to receive the remains, extinguish the fire, and take out the kiln.

In other words, during wreckage work, it is necessary for the crew in the cab 7 to be able to simultaneously see the direction of movement of the fire extinguishing train 5 and the red hot coke loading status, so the fire extinguishing train 5 is equipped with red hot coke. are advanced in a direction such that they are loaded from the rear end side of the receiving tank 6 (the right end side in FIG. 1).

In addition, during fire extinguishing work, the fire extinguishing train 5 can be
is made to advance towards the fire extinguishing tower 8 on the rear end side of the receiving tank 6.

On the other hand, in the preparation work of the coke guide car 3 for unloading the kiln, if the direction of movement of the coke guide car 3 is the same as the direction of movement of the fire extinguishing train 5, the driver's cab 9 of the coke guide car 3 loads the cargo into the receiving tank 6. The coke guide car 3 is moved in the opposite direction to the direction in which the fire extinguishing train 5 travels due to problems such as a longer time for receiving high heat from the red-hot coke.

The main point of the method of the present invention is to arrange a hopper 11 for collecting crushed coke in front of the guide grid 4 located on the traveling direction side of the coke guide car 3 in the coke oven constructed as described above. That is.

The arrangement of the hopper 11 is not particularly limited as long as it is before the guide grid 4 described above, but generally,
As shown in FIG. 2, the dust collecting hood 13 is disposed outside the dust collecting hood 13 and is connected to the dust collecting hood 13 communicating with the dust collecting duct 14 via a duct 15. As shown in FIG.

The crushed coke scattered on the service platform around the kiln mouth is transported to the hopper 1 by a chain conveyor 12 attached to the side of the coke guide car 3 along the front of the coke oven.
1 and collected.

The chain conveyor 12 is constantly driven, and the fallen coke is loaded onto the chain conveyor by any suitable means.

Since it is difficult to transport and collect such fallen coke around the kiln mouth where the kiln is currently being unloaded, the fallen coke that has fallen during the relevant kiln unloading operation will be removed during the next kiln unloading operation. Sometimes they are mainly collected.

The fallen coke collected and deposited in the hopper 11 is introduced into the receiving tank 6 by opening the damper provided at the lower part when the fire extinguishing train 5 comes to the fixed position for the debris receiving work.

The opening/closing operation of the damper can be performed using, for example, a hydraulic cylinder or the like.

In the method of the present invention thus constructed, red-hot coke is loaded on the fallen coke that has been dropped into the receiving tank 6, and the fallen coke is always covered with red-hot coke.

Therefore, the cool portion of the coke debris and the uncarbonized coal are instantly and completely combusted, and as a result, no smoke is generated from the coke debris.

According to the method of the present invention explained above, smokeless processing of fallen coke can be achieved by simply arranging a hopper for collecting fallen coke at a specific position. Dogs contribute to defense.

[Brief explanation of drawings]

FIG. 1 is a schematic plan view showing the overall arrangement of the coke oven, and FIG. 2 is a schematic side view showing the positional relationship between the coke guide vehicle and the fire extinguishing vehicle. 1: extruder, 2: carbonization chamber, 3 two guide cars, 4°4' two guide grids, 5: fire extinguishing train, 8: fire extinguishing tower, 11: hopper.

Claims (1)

[Claims] 1 The fire extinguishing train was moved to receive the red hot coke from the rear end of the receiving tank, and the fire extinguishing train proceeded toward the fire tower from the rear end of the receiving tank to extinguish the fire. At the same time as the work is being carried out, a coke guide car moves in the opposite direction to the traveling direction of the fire extinguishing train, and in order to prepare for unloading from the kiln, the fallen coke is collected in a hopper attached to the coke guide car. In order to collect the fallen coke accumulated in the hopper and introduce it into the receiving tank of the fire extinguishing train, the hopper is placed between two guide grates mounted on the coke guide car. The droplet is arranged in front of a guide grid located in the direction of progress of the preparation work, so that the fallen coke falling from the hopper into the receiving tank of the fire extinguishing train is covered with red-hot coke.
