Abstract

The invention discloses a desulfurization-denitrification-dedusting integrated device of a coke oven, and relates to the technical field of the flue gas treatment. The desulfurization-denitrification-dedusting integrated device of the coke oven comprises a flue gas system, a desulfurization system, a dedusting system and a denitrification system which are successively connected. The outlet of thedenitrification system is connected with a chimney through a draught fan. The desulfurization-denitrification-dedusting integrated device of the coke oven further comprises a flue gas reheating systemand a flue gas heating device. The outlet of the flue gas heating device is connected with the denitrification system, and the inlet of the flue gas heating device is connected with the outlet of theflue gas reheating system and the outlet of the dedusting system. The inlet of the flue gas reheating system is connected with the outlet of the draught fan. The desulfurization-denitrification-dedusting integrated device of the coke oven is suitable for the flue gas treatment of the coke oven, and has the advantages of small pollution, complete purification, low cost, long service life and the like.

Description

technical field

[0001] The invention relates to the technical field of flue gas treatment, in particular to an integrated desulfurization, denitrification and dust removal device for a coke oven. Background technique

[0002] Coking is the process of mixing various raw coals in a certain proportion, heating them to 950-1050°C under air-isolated conditions, drying, melting, cracking, polycondensation, semi-coke shrinkage, and finally forming coke. Coke is the most traditional coal chemical product. It is produced by the coking process. It is a hard, silver-gray massive carbonaceous material. It can be used as a reducing agent, energy source and carbon supply agent for blast furnace ironmaking and cupola. Casting, ferroalloy smelting and non-ferrous metal smelting can also be used in calcium carbide production, gasification and synthetic chemistry and other fields. The coking industry is a heavy polluting industry with complex process and many highly polluting substances prod...
