Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an observation and repair facility for a coke oven combustion chamber for observing or repairing a damaged portion of an inner wall of the combustion chamber of a coke oven.
[0002]
[Prior art]
Conventionally, coke ovens are made of refractory bricks. Combustion chambers are arranged on both sides of the carbonization chamber, and the heat in the combustion chamber is indirectly transferred to the carbonization chamber through the wall, so that the coal in the carbonization chamber is dry-distilled. And coke is manufactured.
Many of these coke ovens have been used for 30 to 40 years, and since they are used under conditions with a large temperature change, the joints of the refractory bricks constituting the combustion chambers and cracks connected to the carbonization chambers are generated. As a result, black smoke is generated due to leakage of dry distillation gas from the carbonization chamber to the combustion chamber, or loss of coke oven generated gas, and further, oxidation of coal due to intrusion of combustion exhaust gas from the combustion chamber into the carbonization chamber, etc. Arise.
Moreover, if the joints and cracks of the refractory bricks are left untreated, the refractory bricks will be lost or dropped with the heat load, and the refractory bricks will deteriorate rapidly and the life of the coke oven will be greatly reduced. is there.
[0003]
As a countermeasure, as described in Japanese Examined Patent Publication No. 7-45666, it moves freely on a rail provided on the upper surface (upper part) of the coke oven in the direction perpendicular to the longitudinal direction of the carbonization chamber. A carriage is provided, and this carriage is provided with an elevating carriage and an elevating guide that run in the longitudinal direction of the carbonization chamber, and a water-cooled lance with a built-in TV camera is taken up and down into the combustion chamber via the elevating guide, and images are taken. A repairing water-cooled lance mounted on another cart that similarly travels in the upper part of the coke oven is moved up and down to perform plasma spraying from the inside of the carbonization chamber to the repair site.
Furthermore, as described in Japanese Patent Publication No. 7-45667, a water-cooled lance with a built-in furnace observation device and a refractory spraying device is inserted into the combustion chamber of the coke oven, and sprayed onto the observed damaged part. Plasma spraying is performed using a nozzle of the apparatus.
In addition, as described in JP 59-136381, JP 3-105195 A, and JP 7-126636 A, an observation apparatus or a repair apparatus such as an observation apparatus and plasma spraying is provided. The inner wall of the carbonization chamber is observed and repaired using a telescopic arm, an observation device, or a traveling carriage equipped with an observation device and a repair device such as plasma spraying.
[0004]
[Problems to be solved by the invention]
However, in the methods described in Japanese Patent Publication Nos. 7-45666 and 7-45667, the coal charging device is centered on the coal storage hopper, from the left side (A furnace group side) to the right side (B furnace). When the work of charging coal into the carbonization chambers of 100 to 120 gates is performed up to the team side), since this coal charging work is a priority work, when a combustion chamber that is to be observed and repaired is generated, Combustion chambers that cannot be observed or repaired are generated due to the work restrictions of the coal charging equipment.
In addition, when deterioration of the combustion chamber progresses and observations in a specific combustion chamber, extension of repair time, and frequency of observation and repair increase, there is a frequent difference between coal charging work and observation and repair work. Therefore, observation and repair itself become difficult, or observation and repair required by the combustion chamber cannot be performed, and the life of the coke oven is reduced.
Furthermore, there is a problem that the operating rate of the observation and repair device is lowered and it becomes difficult to observe and repair the entire combustion chamber.
Moreover, since the depth (height) of the combustion chamber of a normal coke oven is 4 to 5 m, a television camera or plasma spraying that raises and lowers the combustion chamber through a lifting guide provided on a traveling carriage for observation and repair. The stroke of the lance provided with the nozzle is at least 4 to 5 m, and the height of the observation and repair device satisfying this condition is 6 to 7 m in consideration of the configuration of members such as the lifting guide.
On the other hand, a coal storage device for supplying coal to the coal charging device is provided at the upper center of the coke oven, and the observation repair device passes because the allowable passage height of this lower portion is as low as 5 m or less. It is difficult to observe and repair the entire length of the combustion chamber (furnace length).
[0005]
Furthermore, in the methods described in Japanese Patent Publication No. 7-45666, Japanese Patent Application Laid-Open No. 59-136381, Japanese Patent Application Laid-Open No. 3-105195, Japanese Patent Application Laid-Open No. 7-126636, etc., the repair is performed from the carbonization chamber. Concavities and convexities are generated on the wall of the carbonization chamber due to repair of plasma spraying, and when the concavities and convexities are extreme, there are problems such as an increase in the extrusion resistance of coke after dry distillation and an inferior extrusion.
In this way, with conventional combustion chamber observation and repair devices, it is difficult to observe and repair the combustion chamber as needed, and it is impossible to observe and repair all combustion chambers. There was a problem that the lance stroke for observation and repair was expanded by avoiding objects, and the combustion chamber depth direction could not be observed and repaired.
[0006]
The present invention has been made in view of such circumstances, avoiding obstacles such as a coal charging device and a coal storage device on the coke oven furnace, increasing the operating rate of the observation and repair device, and improving the operation rate of the combustion chamber of the coke oven. All observations and repairs can be performed, and the lance stroke can be expanded to observe the entire wall in the depth direction of the combustion chamber with high accuracy and repair. The purpose is to provide equipment.
[0007]
[Means for Solving the Problems]

Observation and repairing devices, which are held and lifted up and down by a lifting guide and attached to the traversing cart so as to be tiltable, are provided on both sides of the coal charging device.
This makes it possible to observe or repair the entire combustion chamber arranged in the longitudinal direction of the coke oven even during the charging of coal into the carbonization chamber, and according to the deterioration state of the combustion chamber. Can observe and repair.
Moreover, since the coal storage device can be avoided by tilting the lifting guide, etc., the operating range per observation repair device can be widened, and the restrictions on observation and repair by the coal charging device are minimized. Can be.
[0008]
Here, the elevating carriage may be attached to an endless track attached in the vertical direction of the elevating guide.
As a result, the overall height of the lance can be maximized by reducing the overall height of the observation and repair device equipped with the lifting guide, etc., and the entire wall from the top to the bottom of the combustion chamber can be observed and repaired. This can extend the life of the coke oven.
[0009]
The observation and repair facility for the coke oven combustion chamber according to the second aspect of the invention is arranged on a rail of a coal charging device installed on the furnace of the coke oven, and a traveling carriage that runs on the rail is further disposed. An observation lance for observing the combustion chamber of the coke oven and / or a repair lance for repairing is mounted on the traveling carriage by placing a transverse carriage traveling in a direction intersecting the traveling direction of the traveling carriage.

Coal is supplied from the storage hopper 16 to the coal hopper 17 of the coal charging vehicle 22, and the wheels 20 and 21 provided at the lower portion of the coal charging vehicle 22 are rotated to move the coal charging vehicle 22 in the Y-axis direction of the coke oven 12. It runs on rails 18 and 19 laid on the furnace (longitudinal direction), cuts coal from coal storage hopper 17, and charges coal into charging chamber 14 from charging chute 23. Coal is cut out from the storage hopper 16 into the coal hopper 17 and charged into all the carbonization chambers 14 so that the coal charging vehicle 22 is placed on the coke oven 12 on the right side from the carbonization chamber 14 at one end of the left side (A furnace group). The range to the other carbonization chamber 14 of (B furnace group) is moved.
In addition, as the work procedure, the charging of coal into the carbonization chamber 14 is prioritized. Therefore, at the position where the coal charging vehicle 22 is moved, the inside of the combustion chamber 13 is observed from the flue hole 12a of the combustion chamber 13. Or repair may not be possible.
[0016]
Therefore, the observation repairing apparatus 10 is arranged on the A furnace group side and the observation repairing apparatus 11 is arranged on the B furnace group side with the coal charging vehicle 22 interposed therebetween.
When the coal charging vehicle 22 is in the position shown in FIG. 1, the observation repair device 10 is used to observe and repair the combustion chamber 13 located on the left side of the coal charging vehicle 22, and the right side of the coal charging vehicle 22. Observation and repair of the combustion chamber 13 located at is performed by the observation repair device 11.

Stop according to the required position of the flue hole 12a of the combustion chamber 13.
Then, by rotating the sprocket 42 attached to the lifting guide 38 by the operation of the driving device and rotating the chain 45 meshed with the sprocket 42 and the sprocket 43, guide wheels 41a, 41b, 41c provided on the lifting carriage 40, The elevator cart 40 is lowered while being guided along the groove 34 of the elevator guide 38 through 41d. At the same time, the observation lance 31 held by the lifting carriage 40 is also lowered.
When the observation lance 31 passes through the flew hole 12a and further descends, the CCD camera (not shown) built in the observation lance 31 is used to observe the presence or absence of joints in the combustion chamber 13 and the presence of a missing portion.
After the observation is finished, the driving device is operated to rotate the sprocket 42, the chain 45 is rotated to raise the elevating carriage 40, and the observation lance 31 is retracted outside the flew hole 12a.
[0017]
Next, after confirming a joint breakage or a defective portion in the combustion chamber 13, the traveling carriage 24 is finely operated, and the repair lance 32 is aligned with the position of the flue hole 12a that has been observed.

Then, after the repair is completed, the sprocket 48 is rotated by operating the drive device, and the repair lance 32 is retracted out of the flue hole 12a to complete the operation.
In addition, since the raising / lowering guide 38 and the raising / lowering guide 39 are being fixed to the tilting base 30 mounted in the traversing carriage 29, when passing under the storage hopper 16, the cylinder provided in the tilting base 30 is operated. Then, by tilting the lifting guide 38 and the lifting guide 39 by 45 to 90 ° with respect to the vertical direction, it is possible to avoid the height restriction and dive under the gantry 15.
The observation / repair device 11 can perform observation and repair in the combustion chamber 13 by the same operation as the observation / repair device 10 described above.
[0018]
Thus, since the observation repairing apparatus 10 and the observation repairing apparatus 11 are arranged across the coal charging vehicle 22, when it is necessary to perform observation or repair in a specific combustion chamber 13, go to the carbonization chamber 14. The combustion chamber 13 can be observed and repaired by using either the observation / repair device 10 or the observation / repair device 11 that is not in position with the coal charging vehicle 22 during the coal charging operation.

Then, all the combustion chambers 13 can be observed and repaired, and the highly accurate combustion chambers 13 that require time can be observed and repaired.
Further, since the observation lance 31 and the repair lance 32 are lifted and lowered in an endless manner using the chains 45 and 51, the height of the lift guides 38 and 39 can be lowered, and the stroke of the observation lance 31 and the repair lance 32 can be reduced. By enlarging, it is possible to accurately observe and repair the entire wall of the combustion chamber 13 in the depth direction.
[0019]
Next, the observation and repair equipment E2 for the coke oven combustion chamber according to the second embodiment of the present invention will be described.

When it is necessary to charge coal into an arbitrary carbonization chamber 14 on the B reactor group side, when the coal charging vehicle 22 moves to the B reactor group side, observation is performed. As a result, the repair device 10 and the coal charging vehicle 22 become incompatible with each other, and it becomes impossible to observe and repair the inside of the combustion chamber 13 on the A furnace group side of the position of the coal charging vehicle 22.
Therefore, before the coal charging vehicle 22 moves to the B furnace group side, the hooked wires 63 and 64 of the suspension devices 61 and 62 in which the observation / repair device 10 is attached to the support 65 of the storage hopper 16 via the arm 60 are provided. It is hung on the traveling carriage 24, the suspension devices 61 and 62 are operated, the observation repair device 10 is lifted, and after passing through the coal charging vehicle 22, the suspension devices 61 and 62 are operated again to lower the observation repair device 10. The collision with the coal charging vehicle 22 is prevented.
Then, it is possible to observe and repair the inside of the combustion chamber 13 in the direction of the A furnace group while avoiding the coalescence of the coal charging vehicle 22, and the inside of the combustion chamber 13 without being restricted by the coal charging vehicle 22. Thus, it is possible to reliably repair the joint breakage and the defective portion, and to extend the life of the coke oven 12.
[0021]
