AI Technical Summary
In existing coke oven gas recovery devices, the gas flow path is short and straight, and the washing oil spray distribution is uneven, resulting in insufficient gas-liquid contact, low benzene absorption rate, and easy local overheating, which affects the solubility of washing oil.
The system employs an inner tank, spiral cooling channels, multiple sets of guide plates, spray components, and water-cooled circulation components. The design incorporates a tortuous gas path to extend contact time, ensuring uniform spraying of the washing oil. The temperature is controlled through water-cooled circulation to prevent localized overheating.
It significantly improves the benzene absorption rate, ensures sufficient gas-liquid contact, avoids local overheating, and improves the recovery efficiency and safety of benzene series compounds in coke oven gas.
