Description

Technical Field

[0001] The utility model belongs to the technical field of coke ovens, and particularly relates to a coke oven airflow regulating device. Background Art

[0002] With the development of large-scale coke ovens, the carbonization chamber of the coke oven is getting longer and longer. How to ensure the uniformity of the temperature in the length of the coke oven is crucial. At present, the means of temperature distribution in the length of the coke oven mainly rely on the airflow distribution at the top of the small flue and the airflow distribution at the inclined channel. During the oven baking process, if other parameters are stable but the horizontal temperature of the coke oven is still not good enough, the size of the gas channel can be controlled by properly adjusting the T-shaped regulating bricks between the adjacent partition walls of the heat storage chamber in the coke oven, where the T-shaped regulating bricks are set in the T-shaped holes at the top of the small flue.

[0003] At present, the commonly used method for regulating the airflow of coke ovens is to use T-shaped regulating bricks. There are round holes on the side of the T-shaped regulating bricks, and a special hook is required to place the T-shaped regulating bricks horizontally on the top of the small flue from the hole reserved at the bottom of the furnace body. This adjustment method requires toggling the regulating bricks to change their arrangement. After repeated measurements and adjustments, the arrangement of the regulating bricks can be finally determined, which is time-consuming and laborious. For coke ovens with good furnace conditions, after the horizontal temperature is adjusted, the regulating bricks do not need to be changed. However, for coke ovens with a long furnace life, due to the increased resistance of the heat storage chamber or more dust accumulation, the dust cannot be completely removed, etc., it is difficult to adjust the horizontal temperature of the coke oven through the regulating bricks. If the regulating holes reserved at the bottom of the furnace body are blocked, the channel will not be able to adjust the size of the gas or air channel through the T-shaped regulating bricks, affecting subsequent production.

[0004] The Chinese patent with the announcement number CN214571690U discloses a coke oven and its adjustable regenerator. Through the metal adjustment plate, the flow area of ​​the gas at the top of the small flue can be changed, thereby adjusting the gas flow in and out of the single regenerator, changing the flow of the heating medium at each part of the combustion chamber corresponding to each single regenerator, and adjusting the temperature of the coke oven. Since a small flue is provided with multiple gas channels separated by partition walls, but the above technical solution puts the metal adjustment plate at the top of the small flue, the gas in the adjacent gas channels will interfere with each other, and the air and exhaust gas in the adjacent gas channels will also interfere with each other, affecting production.
