Corbel structure of coke dry quenching furnace

Abstract

The invention relates toa corbel structure of acoke dry quenching furnace. The corbel structure comprises a corbel column formed by masonry in a ramp area of the coke dry quenching furnace, wherein the masonry comprises corbel support bricks and head-on bricks; each head-on brick is of a T-shaped structure and the head-on bricks are laid at intervals with the corbel support bricks on corresponding sides; bulging wings of the T-shaped head-on bricks are connected sequentially and cover the outer sides of the corbel support bricks to form an integral protective layer. With adoption of the head-on bricks withthe T-shaped structure, the two bugling wings of each T-shaped head-on brick can cover and shield mortar joints of the masonry, loss of refractory mortar in the mortar joint on one side of each head-on brick due to scour of high-temperature recycle gas is avoided, the problems of cracking, collapse and the like of the head-on bricks under the action of shear force are solved, and the service life of the corbel of the coke dry quenching furnace is prolonged effectively.

Description

technical field [0001] The invention relates to the technical field of coking, in particular to a corbel structure of a dry quenching coke oven. Background technique [0002] Compared with traditional wet coke quenching, dry coke quenching has the functions of saving energy, reducing consumption, protecting the environment, and improving the quality of coke, so it is more and more widely used. [0003] As the key equipment in dry coke quenching technology, CDQ oven includes pre-storage area, circular air duct area, inclined air duct area and cooling area from top to bottom. An important device of the ring wall. During the operation of the CDQ oven, the corbel is easy to wear and crack due to the heavy load of the corbel, frequent fluctuations in operating temperature, and long-term erosion by high-temperature coke in the CDQ oven and high-temperature circulating air containing coke powder. , or even collapse. Therefore, the corbel is the life bottleneck of CDQ coke oven r...

AI Technical Summary

Problems solved by technology

When there is a gap 11 between the facing brick layers of the corbel, the facing brick 10 above the gap 11 will generate shear stress at the groove tongue 12, and the shear resistance of the refractory brick is relatively poor, and the facing brick 10 is subjected to shear force The weak point, that is, the groove tongue 12, is prone to breakage, and the broken facing brick 10 will cause the gap 11 between the facing brick 10 of the previous layer to increase, resulting in a chain effect, causing the facing brick above it to break. In severe cases, the entire corbel facing bricks and even the inner ring wall will collapse
