Description

Technical Field

[0001] The invention relates to the technical field of coke oven production, and in particular to a gas supply port regulating tool and a regulating method on a vertical fireway partition wall of a coke oven. Background Art

[0002] In the coke oven production process, especially in the production process of large-volume coke ovens using multi-stage heating technology, it is necessary to ensure that the coke cake matures evenly along the length of the carbonization chamber, and also requires the coke cake to mature evenly along the height of the carbonization chamber, which requires the coke oven combustion chamber to have a good horizontal temperature distribution and good high-direction heating uniformity. In actual production, when the coke cake matures unevenly in any direction, it is necessary to adjust the heating uniformity of the combustion chamber, requiring the adjustment of the vertical fire channel segmented heating, that is, adjusting the size of the air supply port on the vertical fire channel partition wall. However, the outlets of each segmented heating are located in a narrow vertical fire channel, at a certain distance from the furnace top, and the working temperature can be as high as 1300℃. It is difficult to complete its adjustment work without the help of special tools. However, if the adjustment work of the segmented heating is not completed in time, it will seriously affect the normal production of the coke oven.

[0003] The air supply port on the vertical fireway partition wall is often adjusted by adjusting bricks, and the hook head on the adjusting rod cooperates with the hook hole on the adjusting brick, that is, the hook head is hooked into the hook hole and the adjusting brick is moved through the adjusting rod. However, when using this adjustment method, not only is it difficult to align the hook head with the hook hole, but also because it is a single-point push, the adjusting brick is very easy to rotate or difficult to accurately position; therefore, each adjustment takes a long time. Since the vertical fireway is a high-temperature environment, too long an adjustment time will not only damage the adjusting rod, but also have an adverse effect on the coke oven production. Summary of the invention

[0004] The present invention provides an air supply port adjustment tool and an adjustment method on a vertical fire channel partition wall of a coke oven. The shape and size of the adjustment block used are determined according to the shape of the air supply port on the vertical fire channel partition wall and the size of the air supply port before and after adjustment. The adjustment operation can be faster and more convenient, the adjustment bricks can be accurately aligned, and the tool can be coordinated with the cooling air duct to adjust the size of the air supply port on the vertical fire channel partition wall of the combustion chamber at any time under high temperature conditions during the hot production process of the coke oven.
