。However, since coal carbonization is indirect heating through the side walls of brickwork, long-term use may cause coke to fuse with the bricks, collapse of the brickwork side walls, or damage the side walls when taken out of the kiln. Therefore, the life of a normal reactor is said to be about 20 years.

未だ開発されていない。(Problems to be Solved by the Invention) As mentioned above, the hot repair equipment for coke oven carbonization chambers that has been implemented in the past requires the operator to manually inspect an area within 1 to 2 meters from the kiln mouth with the naked eye. Most of the work is carried out by inserting the boom into the center of the furnace, confirming the location to be repaired, and then using a device that can accurately and efficiently repair a wide area, especially the functional structure of the boom body. has not yet been developed.

。"Structure of the Invention" (Means for Solving the Problems) In order to achieve the above-mentioned object, the present inventors installed water cooling pipes vertically at a predetermined interval, and installed a heat insulating material between them. It is characterized by the use of a boom that is connected by two steel plates to form an air cooling area, and has a main pipe that houses the supply pipe for materials for repairing the inside of the furnace and the cable for the camera, etc. We proposed a coke oven thermal spray repair device to Gei. By using this device, despite the long boom, it has excellent heat resistance and cooling efficiency, and can perform hot repairs over a long period of time.

収納する容積を指すものである。(Function) The feature of the thermal spray repair apparatus for a coke oven carbonization chamber of the present invention is that two water-cooled pipes are arranged vertically at a predetermined interval, and the space between them is connected by two steel plates coated with a heat insulating material. A cooling area is formed by air, and in this space, the furnace repair materials (refractory powder for thermal spraying, propane gas, oxygen, cooling water for the tip),
This is because a main pipe is provided to accommodate cables for surveillance cameras, etc., and the predetermined interval refers to the volume that accommodates this main pipe.

ことが大きくなるので、これを避けたものである。The structure has water-cooled pipes on the top and bottom, and the cross section is long in the vertical direction. This allows for sufficient cooling to the tip of the long boom, which can accommodate narrow spaces in the middle, and also ensures the necessary rigidity to support the weight of the main pipe. In addition, when forming a double tube with a cross section close to a right circle like a normal water cooling jacket,
This is to avoid the shortening of the distance to the side wall and the increased exposure to radiant heat from the side wall of the kiln.
