Problems solved by technology

[0005] At present, large-scale coke ovens generally use prefabricated blocks of glazed castables as furnace door lining bricks, which solves the problems of tar penetration and tar removal during the production process; The loss is relatively large. In severe cases, there will be coke on the burner head, and smoke and fire will appear when pushing the coke.

Abstract

The invention relates to a coke oven door double-layer soft sealing structure. An inner ring flexible fire-resistant sealing element is arranged between an oven door lining and an oven door body along the circumferential direction of the oven door body, and an outer ring flexible fire-resistant sealing element is arranged in a knife edge box; and when the oven door of a coke oven is closed, the inner ring flexible fire-resistant sealing element and a coke oven body are compressed to realize inner-layer sealing, and the outer ring flexible fire-resistant sealing element and an oven protection iron piece are compressed to realize outer-layer sealing. Through the double-layer soft sealing structure, the sealing performance of the oven door area of the coke oven is effectively improved, raw gas overflow is inhibited, and energy conservation and consumption reduction are realized.

Description

technical field [0001] The invention relates to the technical field of coke ovens, in particular to a double-layer soft sealing structure for a coke oven door. Background technique [0002] Coke oven is the basic thermal equipment in the coking industry. It is used to provide important coke and gas for the smelting industry. It has the characteristics of high energy consumption and heavy pollution. The coke oven is a high-temperature furnace, and the large surface heat dissipation is one of the reasons for its high energy consumption. With the continuous improvement of national environmental protection requirements, the problem of energy saving and consumption reduction of coke ovens has become increasingly prominent. [0003] The coke oven is generally composed of main structures such as regenerators, ramps, combustion chambers, carbonization chambers, and furnace roofs, as well as auxiliary structures such as other civil engineering foundations and iron parts for furnace ...
