Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coke oven inspection / repair facility and a coke oven repair method capable of observing and repairing damaged bricks in a combustion chamber of a coke oven.

[0002]

2. Description of the Related Art A coke oven is constituted by alternately arranging a plurality of combustion chambers and carbonization chambers via partition walls. The partition walls are subjected to a rapid temperature change in the carbonization process from charging of coal. At the same time, when the kiln is discharged from the kiln, it receives mechanical shock and temperature changes due to the inflow of air due to friction with coke due to mechanical extrusion, which causes joint breakage or breakage on the partition wall and gas leakage occurs. Become. Therefore, in order to extend the life of the coke oven, repair of the partition wall is indispensable.

Therefore, the applicant of the present invention has disclosed in Japanese Patent Laid-Open No.
In Japanese Patent No. 311173, a coke oven inspection having a configuration in which a single water-cooled cylindrical body equipped with an observation device and a repair nozzle capable of thermal spraying or spraying repair at a tip thereof can be inserted into a combustion chamber through a coke oven combustion chamber inspection port.・ Repair equipment was presented. The coke oven inspection / repair method using this coke oven inspection / repair equipment will be briefly described. First, the water-cooled cylindrical body is inserted vertically through the inspection port of the coke oven combustion chamber, and observed vertically and swirled. The location of the partition wall damage is searched using the device. When the repair position is determined, thermal spraying or spray repair is performed using a repair nozzle to close cracks and the like. After the repair is completed, the state of the repair is confirmed with an observation device, and then the water-cooled cylindrical body is taken out of the furnace. By using such a coke oven inspection / repair facility, the coke oven inspection / repair operation can be performed efficiently.

[0004]

However, the coke oven inspection / repair equipment described above still has the following problems to be solved. That is, since the observation device and the repair nozzle are both formed of a single long cylinder, the diameter of the cylinder becomes large, making it difficult to insert through the flew hole, and causing damage to the tube and the flew hole during turning. In addition, since it is attached to the tip of the water-cooled cylindrical body, when a considerable amount of dust is generated in the combustion chamber during spraying or spraying repair by the repair nozzle, the dust is collected at the tip of a fiberscope as an observation device or a small TV. It adheres to the surface of a camera or the like, making subsequent monitoring substantially impossible. In addition, the work of removing dust adhering to the camera surface of the observation apparatus must be performed for each repair work, and the repair time cannot be sufficiently reduced.

[0005] The present invention has been made in view of such circumstances, and it is possible to adhere a repair material to a repaired location while clearly checking the repaired location, thereby reducing the repair time. It is an object of the present invention to provide a coke oven inspection / repair facility and a coke oven repair method capable of improving productivity as well as the coke oven.

[0006]

According to a first aspect of the present invention, there is provided a coke oven inspection / repair facility according to the first aspect of the present invention, wherein a combustion chamber and a carbonization chamber are alternately arranged via a partition wall on a ceiling wall of the coke oven. A trolley is installed so that it can run in the longitudinal direction (furnace length direction), and a traverse can be installed on the trolley so that it can run in the short direction (furnace group direction) perpendicular to the running direction of the trolley. The observation device and the repair device are mounted side by side on the trolley, and the observation device is independently inserted into the combustion chamber through a number of flue holes provided in the ceiling wall of the coke oven and can be moved back and forth. The camera lance is rotatable around, and the repair device is also provided with a repair lance which is inserted into the combustion chamber through the flew hole independently of the camera lance so as to be able to advance and retreat, and is rotatable around the axis.

[0007] In the above configuration, first, the camera lance of the observation device is inserted into the combustion chamber through the flew hole.
A repaired portion such as a crack generated in a partition wall is found, and its position information is transmitted to a control device outside the furnace through a signal line and stored. Since no dust is generated in the combustion chamber at this time, the observation device can accurately confirm the repaired portion and the damage state (the generation of flame from the brick, the size of the crack, and the like). Thereafter, the camera lance is taken out of the furnace from the combustion chamber, and the vertical trolley and the horizontal trolley are driven so that the repair lance is aligned with the flue hole of the combustion chamber, and inserted into the combustion chamber through the flue hole. After maintaining the repair lance at a predetermined position based on the information, a thermal spray material or a spray material is sprayed toward the repair location to close a crack or a joint at the repair location. Thereafter, the repair lance is taken out of the furnace, and the above repair work is performed for other combustion chambers, thereby completing the inspection and repair work of the entire coke oven. In this manner, the camera lance of the observation device and the repair lance of the repair device can be separately inserted into the combustion chamber, and the camera lance is inserted into the combustion chamber where dust is not generated, so that the repaired portion can be reliably located. After confirmation, the repair lance can be inserted into the combustion chamber to attach the repair material to the repair location.

Here, the above-described coke oven inspection / repair facility according to the present invention may have the following configuration. (1) The camera lance of the observation device and the repair lance of the repair device can be configured to be tiltable on the traversing carriage by the tilting device. Therefore, while effectively avoiding various obstacles such as the building structure located above the ceiling wall of the coke oven, the inspection and repair work of the coke oven is performed while moving the observation device and the repair lance in the longitudinal and transverse directions. It can be performed. (2) The trolley can also be connected to a coal-charged vehicle that is disposed on the ceiling wall of the coke oven so as to be able to run in the longitudinal direction. In this case, the traveling trolley can be driven by using the traveling drive source of the coal-loaded vehicle, so that there is no need to equip the traveling trolley with a dedicated traveling drive source.

(3) A repair material supply pipe is provided in the longitudinal direction along the ceiling wall of the coke oven, and a plurality of relay terminals are attached at intervals in the repair material supply pipe. In the moving position, the connecting member can be detachably connected to the repair material supply pipe using the relay terminal. Therefore, it is not necessary to attach large auxiliary equipment such as a cable carrier for supplying a repair material to the repair device. (4) The camera lance and the repair lance may each be configured to be able to turn 360 ° around the axis. Therefore, not only the repaired portion on the wall surface of the partition wall on one side of the combustion chamber but also the repaired portion on the wall surface of the partition wall on the other side and the repaired portion on the wall surface of the partition wall located on the left and right sides thereof are effective. Can be inspected and repaired.

According to a second aspect of the present invention, there is provided a method of repairing a coke oven according to a second aspect of the present invention, wherein a longitudinal carriage travels in a longitudinal direction on a ceiling wall of the coke oven in which a combustion chamber and a carbonization chamber are alternately arranged via partition walls. When repairing a partition wall with a camera lance and a repair lance mounted on a traversing carriage that is mounted on the traverse and that travels in the furnace width direction, it is equivalent to the center of the flue hole in the width direction of the coke oven. The combustion chamber is observed by a camera lance and repaired by a repair lance, and the combustion chamber corresponding to the flue hole at the end in the width direction is repaired from the carbonization chamber side to shut off the ventilation between the combustion chamber and the carbonization chamber. By doing so, it is possible to eliminate cracks and brick joints that conduct between the combustion chamber and the carbonization chamber,
Generation of black smoke can be prevented.
