A cell wall structure of coke oven regenerator

technical field

The invention relates to the technical field of coke ovens, in particular to a cell wall structure of a coke oven regenerator.

Background technique

Modern coke ovens are mainly composed of five parts: regenerator, chute, carbonization chamber, combustion chamber and furnace top area; the regenerator is set at the lower part of the furnace body, and the flue and foundation are below the regenerator. Above the regenerator, the carbonization chamber and the combustion chamber are arranged alternately, the ramp is located between the regenerator and the combustion chamber, and the regenerator and the combustion chamber are connected through the ramp; the top area is set above the carbonization chamber and the combustion chamber .

For large-scale coke ovens, in order to better adjust the temperature and combustion conditions inside the coke oven, the lower adjustment method is often used. The key structure of the lower adjustment method is the grid regenerator, that is, in the regenerator from the machine side to the coke side. Set up a grid wall, the grid wall spacing is two flue widths, and fill the grid bricks between the grid walls for heat exchange. The stable grid wall structure of the regenerator is conducive to heat recovery and is related to the accuracy of gas volume adjustment. If the grid wall collapses or collapses, it is easy to cause gas leakage, and in severe cases, the lower adjustment method will fail. Therefore, a good grid wall structure should have stability and airtightness to ensure the long-term stable operation and precise adjustment of the coke oven.

The Chinese utility model patent with the authorized announcement number CN202754941U discloses "a tamping coke oven with adjustable regenerator compartments", which includes a furnace roof, a carbonization chamber, a combustion chamber, a chute, a regenerator, and a small flue. The furnace top is located at the upper part of the carbonization chamber and the combustion chamber, the carbonization chamber and the combustion chamber are distributed alternately, the regenerator is located at the lower part of the carbonization chamber and the combustion chamber, and is connected with the combustion chamber through a ramp; The chamber wall, furnace roof, carbonization chamber bottom and furnace doors on both sides are enclosed and composed. There are 16 partition walls added in the length direction of the regenerator, and the width of the partition wall is 60mm. It changes the traditional adjustment form of tamping coke oven air or lean gas, and realizes the adjustment of air or lean gas in a single vertical flue of the tamping coke oven combustion chamber, ensuring that the gas in each vertical flue is fully combusted.

The Chinese utility model patent with the authorized announcement number CN216106768U discloses "a coke oven small flue air intake distribution adjustment structure". The regenerator of the coke oven is a grid regenerator; the adjustment structure includes The grate plate adjustment structure and the grate brick adjustment structure; the grate plate adjustment structure is arranged at one or both ends of the regenerator corresponding to the machine side and the coke side, and the rest of the regenerator is provided with a grate brick adjustment structure. The combination of downward adjustment and side adjustment can conveniently, quickly, accurately and effectively adjust the gas and/or air distribution into each compartment regenerator, so that the heating system of the coke oven can be improved and the coke can be improved. The uniform maturity of the coke oven length and the service life of the coke oven can also achieve the purpose of saving energy.

The regenerators in the above two patents both have a gridded regenerator structure, but the main concern is how to distribute and adjust the airflow, and the specific arrangement of the gridded walls of the regenerator is not discussed.
