Description of the Invention: [Technical Field] The present invention relates to a method for repairing a coke oven in which a furnace wall brick including a combustion chamber of a carbonization chamber of a coke oven is repaired and repaired (a method for Repairing a coke oven), in which the combustion chamber and the carbonization chamber are alternately arranged. [Prior Art] The coke oven is arranged along the width direction of the furnace to alternately arrange the carbonization chamber and the combustion chamber for supplying thermal energy to the carbonization chamber, and pass through the furnace wall of the carbonization chamber (to separate the carbonization chamber and the combustion chamber). Heat is supplied from the combustion chamber to the carbonization chamber. Further, the combustion chamber is zoned at a predetermined interval along the length of the furnace to form a plurality of flues. The coal carbon charged in the carbonization chamber is dry-distilled into char, and then pushed out from an oven opening of the carbonization chamber, through which the furnace wall of the carbonization chamber undergoes intense thermal cycling. In addition, when the coke oven is started to operate at a high temperature, the bricks will suddenly change in volume if cooled to normal temperature. Normally, the coke oven is continuously used until the end of its life. Therefore, it is necessary to periodically check whether the wall bricks are cracked, notched, etc., or repaired by spraying, or by partial hot-replacement of the furnace wall tiles. By the partial repair method of the hot refresh, for example, the operation of the carbonization chamber to be subjected to the hot update is stopped, and after the heat treatment is performed in the range in which the refresh operation is to be performed, the repair of the wall brick of the repaired portion is performed. Update 'General 201200586 is to disassemble the brick wall to be repaired'. The new furnace wall brick is stacked and reassembled in the same manner as before the disassembly, and then the temperature is increased to make the carbonization chamber in use become usable. . In the following Patent Document 1, the joint between the wall portion of the unremoved non-repaired portion and the wall portion after the repair of the repaired portion is formed so as to be continuous with the upper and lower joints (gap), and the temperature of the furnace is increased after the update. After the temperature rise, the gap between the furnace wall brick of the repaired portion and the boundary portion of the non-repaired portion of the furnace wall brick is sprayed using the molten material, thereby suppressing the difference in thermal expansion coefficient between the two wall bricks at the time of temperature rise. The boundary is caused to bulge. The furnace wall brick of the combustion chamber can of course also serve as the furnace wall of the carbonization chamber. [Patent Document 1] Japanese Laid-Open Patent Publication No. 2008- 1 693 1 5 SUMMARY OF THE INVENTION However, when the repair range of the furnace wall brick becomes large, that is, since the combustion chamber extends along the length of the furnace, it should be repaired. In the case where the length of the combustion chamber is long, the furnace wall bricks are stacked in a mesh shape as described above. Therefore, it is necessary to stack the entire length of the repairing area, especially in the portion far from the kiln opening. The stacking is carried out because the working space (that is, the width of the carbonization chamber) is narrow, and there is a problem of poor workability. SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object thereof is to provide a method for repairing a coke oven which has good workability in the case where the length of the combustion chamber to which the repairer wall brick is to be renewed is long. In order to solve the above problems, the repairing method of the coke oven of the present invention is to repair the furnace wall brick of the combustion chamber including the carbonization chamber wall of the coke oven.

The room is insulated; (e) The furnace wall of the combustion chamber in the disintegrated area of the inner side wall brick is disassembled in a heat-insulated state. In the coke oven repairing method of the present embodiment, when the kiln opening 1 side is forward and the opposite direction is the inner side, the furnace wall brick renewal repair range of the combustion chamber 22 is divided into: front side furnace wall brick repairing repair area 2 and The side wall bricks are updated to repair area 3. In the present embodiment, the furnace wall of the combustion chamber 22 is divided into two parts: a front side wall brick repair repair area 2 and a back side wall brick repair repair area 3, but the front side wall brick is updated. The repaired area is further divided into: the repairing area of the inner side wall brick and the repairing area of the front side wall brick. That is, the furnace wall bricks of the combustion chamber 22 are stacked in a mesh shape as will be described later, and the repaired area may be divided into a length of a repairing area suitable for performing a series of stacking. After the furnace wall brick of the combustion chamber 22 is divided into the repairing range, the carbonization chamber 2 1 which is a non-repairing portion, that is, the inner side brick wall repairing and repairing area 3 is separated by the heat insulating material 4 heat. In the present embodiment, -9 - 201200586 is a lattice brick 5 assembled on the front side of the heat insulating material 4 of the carbonization chamber 2 1 in the non-repaired portion of the inside to prevent deformation of the combustion chamber 22 of the heat insulating portion. The checker brick 5 is configured, for example, by assembling a rectangular parallelepiped refractory brick into a well shape. The checker brick 5 is characterized in that, for example, the heat insulating material 4 is easily pushed down from the front side. Further, the furnace wall of the carbonization chamber 21 on both sides of the furnace wall repairing and repairing range is also covered with a sheet-shaped heat insulating material 6. After the preparation for the repair work is completed in this manner, as shown in Fig. 1b, the furnace wall bricks 7 of the combustion chamber 22 of the inner wall brick repairing and repairing area 3 are piled up. The stacking of the furnace wall bricks 7 of the actual combustion chamber 22 is to construct a plurality of flue ducts. The flue is constructed by partitioning the inside of the furnace wall of the combustion chamber 22 by a partition at regular intervals. The partition wall of the flue is, for example, described in the aforementioned Patent Document 1, in which the protruding portions called the boring head are alternately inserted into the furnace wall, or as shown in Fig. 2, the partition walls of different lengths are alternately assembled by the furnace wall bricks 7, Thereby, the whole is stacked in a mesh form. Further, the furnace wall brick 7 for the furnace wall is also, for example, protruded downwardly from the boring head 23, and the tamper 23 is fitted into the groove 24 to be mesh-shaped. The furnace wall bricks 7 are stacked in a mesh-like manner in such a manner as to prevent the collapse of the combustion chamber 22 in order to resist the side pressure at the time of coal charging. In this way, in the inner side wall brick update repair area 3, the furnace wall brick 7 of the combustion chamber 22 is stacked in a mesh-like manner as a whole, as shown in the figure lc, the inner side wall brick repairing and repairing area The flue end surface of the front side wall brick of the combustion chamber 22 of the third combustion chamber 22 is flat in the vertical direction and the furnace width direction. Preferably, the partition bricks of the flue are constructed to overlap longitudinal joints (vertical seams). In this way, as will be described later, it can be absorbed:

After the completion of the renewal of the furnace wall brick 7 of the combustion chamber 22 of the inner side wall brick repairing and repairing area 3, for example, the heat insulating material 4 is removed, and as shown in the figure Id, the sheet-shaped heat insulating material 6 is covered (covered) The furnace wall of the carbonization chamber 21 on both sides is shortened toward the front side wall brick repair repair area 2 side, and the front side furnace wall brick renewal repair area 2 side of the carbonization chamber 2 1 on both sides of the rear side wall brick repair repair area 3 is renewed After the end portion is insulated by the heat insulating material 4, the front side wall brick is stacked to renew the furnace wall brick 7 of the combustion chamber 22 of the repairing area 2. In order to prevent deformation during temperature rise after repair, the checker brick 5 is retained. During the stacking process of the furnace wall bricks 7 of the combustion chamber 22 of the front side wall brick renewal repair area 2, the temperature rise of the inner side wall brick renewal repair area 3 is performed. The most important of the temperature rise of the furnace wall bricks is the temperature rise process of about 200 ° C to 300 ° C. The 20 (TC~3 00 °C is a temperature region where the linear expansion rate is significantly increased. If the temperature rise rate of the temperature region is large, the updated furnace wall brick will be cracked and deformed, and a serious situation will break the balance and cause The furnace wall itself collapses. That is, the temperature rise process of the updated furnace wall brick must pass an appropriate time. Thus, in the present embodiment, the furnace wall brick 7 of the combustion chamber 22 of the front side wall brick renewal repair area 2 is In the stacking process, the furnace wall brick 7 of the updated rear side wall brick repairing and repairing area 3 is heated to 200. (: The following can shorten the time required for the heating process and improve the heating efficiency. As shown in Fig. 1 e, if the wall bricks 7 of the combustion chamber 22 of the front side wall brick repair and repair area 2 are piled up, all the heat insulating materials and the front bricks of the front -11 - 201200586 are removed, and The temperature rise of the front side wall brick repair and repair area 2 is started, and the further heating of the inner side wall brick repair and repair area 3 is continued. Thus, the coke oven repairing method according to the embodiment is to repair the repair of the furnace wall brick 7. The area is divided into the inner side and Side; heat-insulating the carbonization chamber 2 1 in the inner side of the brick wall repairing and repairing area 3, and in this state, stacking the inner wall brick of the repairing area 3 to repair the furnace wall brick 7 of the combustion chamber 22 After the stacking of the furnace wall bricks 7 of the combustion chamber 22 of the inner side wall brick repairing repairing area 3 is completed, the carbonizing chamber 2 1 of the inner side wall brick updating and repairing area 3 is insulated, and in this state, the inner wall is insulated. The side wall brick renewal repair area 3 is heated up, and the front side wall brick is piled up to repair the furnace wall brick 7 of the combustion chamber 22 of the repair area 2; therefore, even if the length of the combustion chamber 22 of the repair furnace wall brick 7 is to be updated is long In other cases, the series of lengths of the combustion chamber 22 of the wall brick 7 can be shortened, and the working property of the carbonization chamber 21 is excellent even if the width of the carbonization chamber 21 is narrow. After the stacking of the furnace wall bricks 7 is completed, the front side wall brick repairing and repairing area 2 is heated up, so that the heating efficiency of the furnace wall brick repairing area is good. Further, the inner side furnace wall is in front of the combustion chamber 22 of the repairing repairing area 3. The flue end face of the side wall brick update repair area 2 is on the upper and lower sides The direction and the width direction of the furnace are both flat, so that it can be absorbed: the furnace wall brick 7 of the combustion chamber 22 of the repairing area 3 of the inner wall brick of the temperature rising first, and the combustion chamber of the repairing area 2 of the side wall brick of the front side of the heating layer 2 Differences in thermal expansion characteristics between two wall bricks 7
