With the development of the coke oven to the large-scale direction, the heating capacity of the coke oven is larger and larger, the heat storage area of the heat storage chamber is required to be larger and larger, and in order to put more checker bricks, the size of the heat storage chamber of the coke oven is longer and longer in the machine side-coke side direction, and the height is also higher and higher. The increase of the height of the regenerator not only increases the consumption of refractory materials, but also increases the elevation of all matched equipment, and finally increases the construction cost of the coke oven. And from the current condition of production operation, even if the regenerator is heightened, the condition that the temperature of the waste gas is higher still occurs in some large coke ovens.
The regenerator of the prior large coke oven generally adopts a grid structure, each grid regenerator corresponds to two vertical flame paths, the top of each grid regenerator is correspondingly provided with two inclined paths, and the inclined paths are respectively connected with two adjacent combustion chamber vertical flame paths above the regenerator. The width of the lower part of the chute along the machine side-coke side direction is generally 80-110mm, the length of the conventional large-sized coke oven single-lattice regenerator is about 1000mm, when the coke oven is produced, descending air flow is rapidly sprayed into the regenerator with the length of 1000mm from two long and narrow channels with the width of about 80-110mm, and the distance between the top of the lattice brick and the outlet of the lower part of the chute is generally relatively close, so that almost no air flow passes through the holes of the top-layer lattice brick far from the outlet of the chute, and a large amount of heat exchange area is wasted. The top of the regenerator is an air flow high temperature area, which is the area with highest heat exchange efficiency, but because the utilization efficiency of the checker bricks at the top of the regenerator is reduced, the height of the regenerator is wasted, and the temperature of waste gas is possibly too high, so that the coking heat consumption is increased.

Further, the blocking piece is a horizontal baffle plate 5, a triangular prism baffle plate 7 or an inclined baffle plate 8.
Further, the horizontal baffle plate 5 is arranged at the top of the uppermost layer of checker bricks of the regenerator 1, and the horizontal baffle plate 5 consists of a baffle plate body 52 and supporting legs 51; at least 3 supporting legs 51 are uniformly arranged at the bottom of the baffle body 52 along the circumferential direction, and the heights of the supporting legs 51 are not less than 20mm; the diameter of the end of the leg 51 in contact with the checker brick 4 is larger than the maximum width or diameter of the checker brick hole; the top of the uppermost layer of lattice bricks is provided with a groove, and the supporting legs 51 are embedded in the groove to fix the horizontal baffle plate 5; the distance between the active surface of the horizontal baffle 5 and the lower edge of the chute exhaust gas outlet is at least 50mm.
Further, the axis of the triangular prism stop block 7 is horizontally arranged at the top of the uppermost layer of checker bricks of the regenerator 1, 2 inclined planes are respectively vertical to the corresponding side chute waste gas outlets, and the distance between the inclined planes and the end face of the corresponding chute waste gas outlet is not less than 50mm; the triangular prism stop 7 consists of a stop body and supporting legs; at least 3 supporting legs are uniformly arranged at the bottom of the stop block body along the circumferential direction, and the heights of the supporting legs are not less than 20mm; the top of the uppermost layer of lattice bricks is provided with a groove, and the supporting legs are embedded in the groove to fix the triangular prism stop block 7.

The baffle body 52 of the horizontal baffle 5 has a flat plate structure, and as shown in fig. 1-3, the thickness of the baffle body 52 is at least 30mm, so that the baffle body is ensured to have enough strength when impacted by air flow.

The blocking member can also be suspended in the regenerator headspace 9, as shown in fig. 5, with the upper end of the inclined baffle 8 fixedly connected with the chute zone 2 masonry.
