Problems solved by technology
The technical scheme disclosed above shows that the effect is not ideal through simulation and semi-industrial tests. The upper part of the suspended partition device is easily damaged after a period of use; The gas distribution of the divided upper and lower airways is not uniform, the processing capacity is not increased, and it is not easy to locate and fall off when the inclined arch is built, and the structural strength is insufficient

Embodiment Construction
[0022] The specific embodiments of the present invention will be further described below in conjunction with the drawings:
[0023] Such as figure 1 , figure 2 As shown, a novel dry quenching furnace ramp structure of the present invention includes a wall 1, a corbel 2, a corbel ring beam 3, and a partition wall 4 in the ramp area. The partition wall 4 is at least arranged along the height On the 2nd floor, the chute area is divided into more than 3 parallel air flow channels; and from top to bottom, the gas flow cross-sectional area of each air flow channel gradually increases; the corbels are arranged in 2 sections, each section corresponding to a different height The thickness of the corbels 21, 22, and 23 gradually increases from top to bottom. A boss structure 5 is formed at the edges of two adjacent corbels, and the two ends of the partition wall 4 are placed on the corresponding bosses. Structure 5.
[0024] The dividing wall 4 is arranged in two layers along the height...

The invention relates to a novel dry quenching furnace ramp structure, which comprises a ramp zone inner wall, corbels, a corbel ring beam and partition walls, wherein at least two layers of the partition walls are arranged along a height direction, a ramp zone is divided into more than three parallel gas flow channels, the gas flowing cross-section areas of various gas flow channels are graduallyreduced from top to bottom, the corbels are arranged correspondingly to the partition walls one-to-one in a layered manner, the thicknesses of various layers of the corbels are gradually increased from top to bottom, a boss structure is formed at the edge positions of the two adjacent layers of the corbels, and both ends of the partition wall are overlapped on the corresponding boss structure. According to the present invention, the novel dry quenching furnace ramp structure can effectively improve the treatment capacity of the dry quenching furnace, increase the strength of the ramp zone, and achieve the positioning building of the partition wall, such that the partition wall is fixed firmly and does not easily shed.
Description
Technical field [0001] The invention relates to a dry quenching furnace body structure, in particular to a novel dry quenching furnace chute structure. Background technique [0002] Dry quenching is relative to wet quenching. It is a quenching method that uses inert gas to cool the red coke. During the CDQ process, the red coke is pushed out from the coking chamber of the coke oven and then loaded into the rotating coke tank. The coke tank truck travels to the bottom of the hoist derrick, and the coke tank is lifted by the hoist to load the red coke from the top of the CDQ. The gas is blown into the red coke layer of the dry quenching furnace by a circulating fan to absorb the sensible heat of the red coke, and the cooled coke is discharged from the bottom of the dry quenching furnace. [0003] The dry quenching coke oven usually adopts a shaft furnace structure with a circular cross section, which is divided into a pre-storage area, an annular duct area, a chute area and a coolin...
