Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a coke oven diagnosis and / or repair apparatus for hot observation and diagnosis of the damage condition of a wall refractory in a coke oven carbonization chamber, or for repairing a wall refractory based on the observation and diagnosis results. It is.
[0002]
[Prior art]
The wall of the coke oven carbonization room is covered with refractory brick. If the refractory on the wall surface is damaged such as joint breakage, crack generation, chipping of brick, etc., the generated coke oven gas flows from the carbonization chamber into the combustion chamber to cause incomplete combustion, or the furnace wall of pyrolytic carbon. Increasing the adhesion of the coke to the damaged part of the produced coke causes a problem of jamming.
[0003]
Various methods or devices have been proposed to repair damage to refractories on the wall of the carbonization chamber. Patent Literature 1 discloses that the position of the wall of the carbonization chamber to be repaired is accurately grasped and repaired, adhered carbon and degraded refractory are removed to form a sound repaired part, and the brick surface after repair is flattened. A diagnostic repair apparatus for a coke oven which can be repaired and can perform a strong and long-life repair is described.
[0004]
As shown in FIG. 1, the diagnostic repair device described in Patent Literature 1 has a carriage (insertion carriage 3) including an observation diagnosis unit 1 and a repair unit 2, and the insertion carriage 3 is driven by wheels or sleds 46 in a coke oven furnace. It can be grounded to the bottom 52 and can move forward and backward in the furnace chamber. The insertion trolley 3 provided with the diagnostic repair unit can be installed on the traveling trolley 30. The traveling carriage 30 can travel on rails 33, and thereby moves to a furnace chamber where repairs are to be performed. The insertion carriage 3 travels on a rail or a receiving roller 34 on the traveling carriage 30. The diagnostic repair device includes a carbon combustion removing device, a mechanical fray removing device 10, and a thermal spraying device.
[0005]
The insertion trolley 3 is inserted into the carbonization chamber 51 and stopped near a predetermined position to be repaired. Then, the vicinity of the position to be repaired is observed by scanning the observation and diagnosis device, and the position to be repaired is determined. The repair can be performed by the repair device 2 such as the carbon combustion removing device, the mechanical fray removing device, and the thermal spraying device while accurately determining the coordinates of the position to be repaired determined by the observation and diagnosis device. Since the mechanical fray removing device 10 can rotate the plate-like rotary blade 9 attached to the tip of the arm and remove the refractory whose brick surface has deteriorated with a mechanical frit by the tool 15 attached to the tip of the plate-like rotary blade. Then, the repair refractory layer formed by the thermal spraying performed thereafter adheres firmly to the brick, and the life of the repair refractory can be improved.
[0006]
As the observation and diagnosis unit 1, the one described in Patent Document 2 can be used. In Patent Literature 2, a camera having a line-shaped or slit-shaped field of view is stored in a camera storage case, and an image of a wall surface of a coke oven carbonization chamber reflected by a mirror tube arranged in a direction of the camera's field of view is captured. By moving the observation / diagnosis device in the carbonization chamber while performing imaging, a two-dimensional image of the wall surface of the carbonization chamber can be obtained.

[0008]
[Problems to be solved by the invention]
The diagnostic and repair device of the coke oven is inserted into a high-temperature carbonization chamber to diagnose and repair the furnace wall. Therefore, the insertion cart 3, the observation and diagnostic device, etc. are all water-cooled and protect the main body and internal equipment. I have. However, since the plate-shaped rotary blade 9 attached to the end of the arm of the mechanical fray removal device 10 cannot be housed in a water-cooled box because of the function to be performed, it is directly exposed to the high-temperature atmosphere in the furnace. For this reason, the tool 15 attached to the tip of the plate-shaped rotary blade may be worn away, resulting in reduced cutting ability or damage to the tool body. Although it is conceivable to directly inject cooling water to the plate-shaped rotary blades 9 using a cooling water nozzle that injects water, it is possible to sufficiently cool the plate-shaped rotary blades 9 by injecting water only from the arm side. In some cases, the plate-like rotary blade 9 holding the tool was deformed due to thermal strain caused by single-sided cooling. If water is to be sprayed from the opposite side of the arm 5 as well, the structure of the device around the plate-shaped rotary blade will be unnecessarily complicated, and maintenance will be inconvenient, which is not preferable as a device to be inserted into a high-temperature furnace. In addition, when the water injection amount is increased, excess water scatters on the bricks on the furnace wall and the furnace bottom, which causes damage to the furnace bottom bricks.
[0009]
The mechanical fray removing device 10 presses the arm 5 having the plate-shaped rotary blade 9 at the tip against the furnace wall surface, and removes the furnace wall surface by the pressing pressure. However, the breaking condition differs depending on the condition of the furnace wall surface, and the furnace wall surface may be excessively cut or the mechanical breaking device may generate vibration depending on the location.
[0010]
In the diagnostic / repair device to be inserted into the coking chamber, the depth of the coking chamber is about 16 m and the height is about 6 m, whereas the width of the coking chamber is about 0.4 m, which is extremely small. The width of the diagnostic / repair device is often set to be just the size of the carbonization chamber. Therefore, in the diagnosis / repair device in which the observation and diagnosis unit 1 and the repair unit 2 are installed at the tip of the insertion trolley 3, and the insertion trolley 3 is placed on the traveling trolley and inserted into the carbonization chamber, FIG. As shown in the figure, if there is a slight deviation between the height direction of the carbonization chamber 51 to be inserted and the height direction of the diagnosis / repair device, the diagnosis / repair device cannot be inserted into the carbonization chamber. On the other hand, in a coke oven that has been used for a long period of time and has been aged, the rail portion on which the traveling vehicle 30 travels may not be able to maintain horizontality due to sinking or uplift. An inclination occurs between the height direction and the height direction of the diagnostic / repair device, and the diagnostic / repair device cannot be inserted into the carbonization chamber. Also, as shown in FIG. 11B, even if a slight deviation occurs between the longitudinal direction of the carbonization chamber 51 and the insertion direction of the insertion cart 3, the diagnosis / repair device may be inserted into the carbonization chamber. Can not be done. When the traveling vehicle 30 travels on the rails and stops in front of the predetermined carbonization chamber 51, the traveling vehicle angle at the time of stoppage becomes inconsistent, and as a result, the diagnosis / repair device cannot be inserted into the carbonization chamber. Sometimes.
[0011]
When the diagnostic function and the repair function are provided on one traveling vehicle 30, it is conceivable to individually have the inserting vehicles 3. However, if a plurality of inserting vehicles 3 are individually installed on the traveling vehicle 30, The width becomes wide, and it becomes difficult to install the traveling vehicle 30 in the coke oven. Equipment costs also increase.
[0012]
A first object of the present invention is to provide a repair apparatus for a coke oven equipped with a mechanical fray removal device 10 having plate-shaped rotary blades 9 that can appropriately cool the plate-shaped rotary blades 9. And It is a second object of the present invention to provide a repairing device that enables stable mechanical fraying regardless of the condition of the furnace wall surface. Further, in the diagnostic / repair device in which the observation and diagnosis device and the repair device are installed at the tip of the insertion truck 3 and the insertion truck is placed on the traveling truck and inserted into the carbonization chamber, the inclination and angle of the traveling truck may be out of order. A third object is to provide a diagnosis / repair device which can be inserted even into a carbonization chamber. A fourth object of the present invention is to provide a diagnosis / repair device capable of performing both diagnosis and repair without increasing the width of the traveling vehicle.

[0018]
The insertion cart 3 including the observation and diagnosis unit 1 and the repair unit 2 is grounded to the coke oven bottom 52 by wheels or sleds 46, and can move forward and backward in the furnace chamber. The insertion carriage 3 is moved forward and backward by an insertion driving unit (not shown) arranged outside the coke oven furnace.

[0023]
The present invention for achieving the first object will be described.
[0024]
INDUSTRIAL APPLICABILITY The present invention can be applied to a coke oven repairing apparatus provided with a mechanical fray removal device for removing the carbonized wall surface brick surface and / or adhering carbon with a mechanical fray. It may be a dedicated repair device or a diagnostic repair device capable of performing both coke oven diagnosis and repair.
[0025]
As shown in FIG. 2, the mechanical fray removal device 10 includes a plate-like rotating blade 9 at the tip of the arm 5. Taking the diagnosis / repair device described above as an example, the drive unit 4 is vertically rotated using the first arm 6 that rotates in the furnace in the vertical direction, and the second arm is attached to the distal end of the first arm 6. 8 has a left-right rotation mechanism 7. In this case, the arm 5 to which the plate-shaped rotary blade 9 is attached is the second arm 8. By turning the second arm 8 left and right, the tool 15 attached to the outer periphery of the plate-shaped rotary blade 9 is pressed against the furnace wall surface, and the furnace wall surface can be chipped.
[0026]
The mechanical fray removal device 10 includes a cooling water nozzle 11 that injects cooling water from the arm 5 side toward the plate-shaped rotary blade 9. The plate-shaped rotary blade 9 is provided with a notch 12 or an opening 13 through which the injected cooling water passes. Thereby, the cooling water injected from the arm side can reach the side opposite to the arm 5 through the notch 12 or the opening 13. Further, a cover 14 that covers a part or most of the plate-shaped rotary blade 9 is disposed at the further tip side of the plate-shaped rotary blade 9, and the cooling water that has reached the side opposite to the arm 5 is cooled by the cover 14. The reflected light reaches the surface of the plate-shaped rotary blade 9 opposite to the arm, and this surface can be cooled.
[0027]
In the mechanical fray removal device 10 of the present invention, since the cooling water is injected only from the arm side, the cooling water nozzle 11 can be arranged on the arm side. Therefore, there is no need to dispose a cooling water nozzle that sprays from the side opposite to the arm, so there is no need to dispose a complicated cooling water pipe around the plate-shaped rotary blade. Since the cooling water is sprayed from both surfaces of the plate-shaped rotary blade 9 to be cooled uniformly, it is possible to prevent the occurrence of thermal distortion and to prevent the deformation of the tool holder.
[0028]
As the notch 12 or the opening 13 disposed on the plate-shaped rotary blade 9 and through which the injected cooling water passes, the following embodiments can be adopted.
[0029]
In the example shown in FIGS. 3A and 3B, a shape having a large number of radial branches can be adopted as the shape of the plate-shaped rotary blade 9. At the tip of each branch, a tool 15 for razor is attached. The space between the branches is the cutout 12 through which the injected cooling water passes. The cooling water jetted from the cooling water nozzle 11 toward the plate-shaped rotary blade 9 from the arm side repeatedly collides with the radial branch and passes through the cutout portion 12 as the plate-shaped rotary blade 9 rotates. When the cooling water collides with the radial branches, the arm side of the plate-shaped rotary blade 9 is cooled. When the cooling water passes through the notch 12 and collides with the cover and rebounds, the side of the plate-shaped rotary blade opposite to the arm is cooled.
[0030]
In the examples shown in FIGS. 3C and 3D, the shape of the plate-shaped rotary blade 9 can have a shape having a large number of holes. The hole formed in the plate-shaped rotary blade 9 becomes the opening 13 through which the injected cooling water passes. The cooling water nozzle 11 is disposed so as to face a hole opened in the plate-shaped rotary blade. With the rotation of the plate-shaped rotary blade 9, when the position of the hole coincides with the jetting direction of the cooling water nozzle, the cooling water passes through the hole and cools the opposite side of the plate-shaped rotary blade from the arm as in the above case. When the position of the hole is different from the jetting direction of the cooling water nozzle, the cooling water cools the arm side of the plate-shaped rotary blade.
[0031]
When sufficient cooling water is injected to cool the plate-shaped rotary blades 9, some of the cooling water is heated by the high-temperature plate-shaped rotary blades 9 and evaporates. After cooling, it falls down as it is. The cooling water dropped on the furnace bottom 52 of the coking chamber cools the furnace bottom bricks and shortens the life of the bricks. It is also conceivable to provide a container for receiving cooling water below the plate-shaped rotary blade 9. The arm 5 having the plate-shaped rotating blades is provided so as to be movable, and the container for receiving the cooling water needs to be moved together with the moving arm. Therefore, it is necessary to connect and install the arm 5 itself. Ultimately, the capacity of the container will be limited to a certain size, and during the repair in the carbonization chamber, the container will be filled with cooling water and overflow.
[0032]
In the present invention, as shown in FIG. 2, the above problem can be solved by disposing a cooling water evaporator 18 having a heat storage body 16 having a large specific surface area below the plate-shaped rotary blade 9. . The heat storage body 16 having a large specific surface area corresponds to, for example, a lump of stone or iron having a size of about several cm. The blocks of stone and iron have sufficient specific heat, and when inserted into a high-temperature carbonization chamber, the temperature of the blocks themselves rises and functions as a heat storage body. When the excess cooling water falls from above the heat storage body 16 due to the large specific surface area, the cooling water comes into contact with a sufficiently large surface of the heat storage body 16 and the cooling water is transferred to the heat storage body 16. Since the water evaporates by absorbing the stored heat, the cooling water does not further fall and reach the furnace bottom. The heat storage body 16 having a large specific surface area has a specific heat of 0.45 × 10 ^Three Any type may be used as long as it is not less than J / kg · K and the average size of each heat storage element is not more than 2 cm. Stone, various ceramics, iron blocks, iron parts such as bolts, various metal blocks, and metal wires are equivalent. Such a heat storage body 16 may have a bulk capacity of about 1000 cc or more, may be housed in a container 17 to form a cooling water evaporator 18, and may be disposed below the plate-shaped rotary blade 9.
[0033]
When the coke oven carbonization chamber is repaired using the coke oven repair apparatus of the present invention, the temperature in the carbonization chamber is not constant. While the temperature varies depending on the operation state of the carbonization chamber, the temperature may vary for each repaired part even in the same carbonization chamber. Regarding the cooling water flow rate injected to cool the plate-shaped rotary blade 9, even if the optimum cooling water flow rate is set at a specific coking chamber furnace temperature, if the coking chamber temperature is higher than the specific temperature, The cooling water is insufficient and the plate-shaped rotary blade 9 is not sufficiently cooled. If the temperature of the carbonization chamber is lower than the specific temperature, the amount of heat stored in the cooling water evaporator 18 disposed below the plate-shaped rotary blades 9 is insufficient, and the excess cooling water cannot be sufficiently evaporated. Cooling water will spill on the furnace bottom 52. On the other hand, when the carbonization chamber temperature is low, the plate-shaped rotary blade 9 can be sufficiently cooled even if the flow rate of the cooling water is reduced. That is, the optimum cooling water flow rate varies depending on the temperature in the carbonization chamber. By controlling the cooling water amount to the optimum cooling water amount for each temperature, the cooling water evaporator 18 can sufficiently cool the plate-shaped rotary blades 9 to remove excess cooling water. It becomes possible to evaporate sufficiently.
[0034]
According to the present invention, a thermometer 21 for measuring at least one of a furnace atmosphere temperature, a repair apparatus temperature, a furnace wall temperature, and a furnace bottom temperature is provided, and a flow rate of cooling water injected from the cooling water nozzle is measured by the thermometer. By determining based on the temperature results, it is possible to always maintain the optimum cooling water flow rate regardless of the temperature in the carbonization chamber, and to protect the plate-shaped rotating blades sufficiently while surplus cooling water scatters to the furnace bottom. Can be minimized. As the temperature measuring means in the carbonization chamber, a thermometer for measuring at least one of the furnace atmosphere temperature, the repair device temperature, the furnace wall temperature, and the furnace bottom temperature may be provided.
[0035]
It is preferable that the flow rate of the cooling water injected from the cooling water nozzle 11 for cooling the plate-shaped rotary blades 9 is in a range of 0.1 to 1.0 liter / minute. If the flow rate of the cooling water is less than 0.1 liter / minute, the cooling of the plate-shaped rotary blades may be insufficient even when the temperature in the carbonization chamber is lowered. Also, if the flow rate of the cooling water exceeds 1.0 liter / minute, the amount of the cooling water becomes excessive, and even if the cooling water evaporator 18 is applied, the excess cooling water may not be sufficiently evaporated.
[0036]
The present invention for achieving the second object will be described.
[0037]
In a coke oven repairing apparatus equipped with a mechanical fray removing device 10 for removing the brick surface and / or adhering carbon by mechanical filing, the mechanical fray removing device 10 moves the rotating plate-shaped rotating blades 9 to the carbonizing chamber wall surface. It is done by pressing. In a conventional mechanical fray removal device, fraying is performed with a constant pressing force against the wall of the carbonization chamber.
[0038]
The repairing apparatus of the present invention has a hardness evaluation device 26 for evaluating the hardness of the wall of the carbonization chamber. The hardness evaluation device 26 evaluates the hardness of the wall of the carbonization chamber for performing the fraying. In the pressing adjustment device 25, one or both of the rotational speed of the plate-shaped rotary blade 9 and the pressing force P against the carbonizing chamber wall surface are determined based on the evaluated hardness of the carbonizing chamber wall surface. When the hardness of the carbonization chamber wall surface where filing is performed is high, one or both of an increase in the pressing force P and an increase in the rotation speed are performed. On the other hand, when the hardness of the carbonization chamber wall surface where the fraying is performed is low, one or both of the reduction of the pressing force P and the reduction of the rotation speed are performed. Thereby, even in a place where the hardness of the carbonization chamber wall surface where filing is performed is low, occurrence of excessive shaving of the wall surface due to filing can be prevented. Further, even when the hardness of the wall surface of the carbonization chamber for performing the fraying is higher than usual, the fraying can be performed without lowering the fraying efficiency.
[0039]
If the hardness of the wall surface of the carbonization chamber is high, or if the pressing force P is excessively large even when the wall surface strength is low, smooth fraying cannot be performed and large device vibration occurs. In addition, the wall surface is locally damaged such as chipping, so that a smooth chipping surface cannot be obtained. According to the present invention, one or both of the rotation speed and the pressing force P of the plate-shaped rotary blade 9 can be controlled in accordance with the hardness of the wall surface. The device vibration can be prevented by reducing one or both of the rotation speed and the pressing force P.

It is preferable that the hardness evaluation device 26 that evaluates the hardness of the carbonization chamber wall surface obtains the hardness of the carbonization chamber wall surface based on the actual cutting allowance by the mechanical filing device 10. When a constant pressing force P and a certain number of rotations are applied by the mechanical filing device 10 to perform fuzzing, if the hardness of the wall surface is low, the cutting allowance in one filing operation increases. Conversely, the higher the hardness of the wall, the smaller the cutting allowance. Therefore, it is possible to evaluate the hardness of the wall surface by detecting the actual cutting allowance in the filing operation. This method is suitable because it is not necessary to attach a hardness tester separately from the main body of the mechanical shearing device, and the configuration of the device is not complicated.
