Description
Technical Field
The utility model belongs to the technical field of tail coke recycling flue gas treatment, and particularly relates to a flue gas treatment device for coke oven tail coke recycling.
Background
In the production process of the coke oven, a small amount of red coke is scattered beside the oven door after the oven door of the coke oven is removed, and the currently common recovery and treatment mode of the part of coke is as follows: the red coke is flushed to a tail coke recovery system by utilizing high-pressure water flow, the red coke is extinguished by the water, and the extinguished coke is temporarily stored in a coke bin of the tail coke recovery system and is periodically discharged to a tail coke recovery tank. In the process, when the coke is extinguished by water, steam is generated and a large amount of smoke dust is carried and directly discharged to the atmosphere through a small chimney, the smoke gas contains a large amount of coke breeze and harmful substances, if the smoke gas is directly discharged into the atmosphere, the air can be seriously polluted, and the smoke gas does not meet the requirement of environmental protection.
Disclosure of Invention
