Dividing wall structure of coke oven regenerator

Technical Field

Background

The modern coke oven mainly comprises five parts, namely a regenerator, a chute, a carbonization chamber, a combustion chamber and an oven top area; the heat accumulating chamber is arranged at the lower part of the furnace body, and a flue and a foundation are arranged below the heat accumulating chamber. The coking chambers and the combustion chambers are arranged above the regenerative chambers at intervals, and the inclined passages are positioned between the regenerative chambers and the combustion chambers and are communicated with the combustion chambers through the inclined passages; a furnace top area is arranged above the carbonization chamber and the combustion chamber.

For a large coke oven, in order to better adjust the temperature and the combustion condition in the coke oven, a lower adjusting mode is mostly adopted, the key structure of the lower adjusting mode is a cellular heat storage chamber, namely, cellular walls are arranged in the heat storage chamber from the machine side to the coke side, the space between the cellular walls is the width of two vertical flame paths, and lattice bricks are filled between the cellular walls for heat exchange. The stable regenerator box wall structure is favorable to heat recovery, and is concerned with the accuracy of tolerance regulation, if the box wall collapses or collapses, causes the gas blowby easily, leads to the lower part regulation mode to become invalid when serious. Therefore, a good grid wall structure has stability and air tightness, and long-term stable operation and accurate adjustment of the coke oven are ensured.

The method changes the adjustment form of the air or the lean gas of the traditional tamping coke oven, realizes the adjustment of the air or the lean gas of the single vertical flue of the combustion chamber of the tamping coke oven, and ensures the full combustion of the gas of each vertical flue.

The Chinese utility model patent with the granted publication number of CN216106768U discloses a distribution and adjustment structure for the air input of a small flue of a coke oven, wherein a regenerative chamber of the coke oven is a cellular regenerative chamber; the adjusting structure comprises a grate plate adjusting structure and a grate brick adjusting structure which are arranged in the same coke oven; the grate plate adjusting structure is arranged at one end or two ends of the regenerator corresponding to the machine side and the coke side, and the grate brick adjusting structure is arranged at the rest parts of the regenerator. The adjustment mode combining the downward adjustment mode and the side adjustment mode is adopted, the distribution amount of coal gas and/or air entering each cellular regenerator can be conveniently, quickly, accurately and effectively adjusted, the heating system of the coke oven is more perfect, the uniform maturity of the coke along the length direction of the coke oven and the service life of the coke oven are improved, and the purpose of saving energy is achieved at the same time.
