Embodiment Construction
[0008] The typical characteristics of the double-divided flue structure of conventional technology are as follows: figure 1 , figure 2 As shown: there are two separate flues 1 on both sides of the machine and coke, and an exhaust gas pan 2 is arranged on both sides of the machine coke below each combustion chamber of the coke oven. The partition wall 3 divides the small flue from the middle into two parts, the machine side and the coke side, and above the small flue are grate bricks 5 and checker bricks 6 . The air 7 enters the small flue respectively from each waste gas tray 2, passes through the grate brick 5 and enters the checker brick 6 of the regenerator. After reversing, the waste gas 8 burned in the coke oven passes through the checker brick 6 of the regenerator down through the grate brick 5 and enters the small flue, collects in the small flue and enters the two sides of the coke through the exhaust gas tray 2 at the end The sub-flue 1.

The invention relates to a branch flue structure at two branch sides at the coke side of a small flue air-flow machine for a coke furnace. That is, the invention provides a coke furnace with only one flue and only one exhaust gas disc under each charring chamber so as to simplify the foundation structure and layout of the coke furnace, reduce near 50% reversing mechanism, hence reduce the investment, simplify operation, and be economic and practical. The basic principle for the invention is: only one flue is provided for the coke furnace, and only one exhaust gas disc is provided under each charring chamber. Two small flues are provided under each heat accumulating chamber, wherein, 1# small flue is divided into two sections, 1 / 2 of which is communicated directly with the exhaust gas disc, another 1 / 2 is communicated with 2# small flue through a communicating hole in the partition wall between the two small flues, and then is also connected with the exhaust gas disc. A balancing passage that passes through the partition wall between the two small flues is provided between checkered bricks and the two small flues. The exhaust gas enters into the balancing passage through the checkered bricks, directly enters into the exhaust gas disc via grate bricks and through 1# small flue, or enters into the only sub flue through the 2# small flue by a roundabout route from the same exhaustgas disc.
Description
Technical field: [0001] The invention relates to a coke oven small flue gas flow machine coke side two-divided single-sided flue structure method. Background technique: [0002] There is a separate flue on both sides of the machine and coke in the conventional horizontal chamber coke oven, and at least two waste gas pans are arranged under each combustion chamber. The exhaust gas enters the two sub-flues on the coke side from the regenerator through the small flue through the grate bricks and the two exhaust pans at the end; Reach the regenerator. The machine and coke sides of this structure each have a set of waste gas trays and reversing devices, and the structure complexity of the coke oven foundation is increased, so the investment is increased. Invention content: [0003] The present invention is to design a coke oven with only one sub-flue, and only one exhaust gas tray under each combustion chamber, so that the basic structure and layout of the coke oven are simpl...
