The invention relates to the technical field of semi-
coke wastewater treatment, in particular to an
ammonia distillation and dephenolization
coupling device for semi-
coke production
wastewater. The device comprises a heating mechanism, a
spray tower is erected above the heating mechanism, a heat exchange mechanism is installed on the side wall of the
spray tower, a preheating mechanism is arrangedon the side, away from the heat exchange mechanism, of the
spray tower, and the preheating mechanism is connected with the heating mechanism; and an air conveying mechanism is mounted on the heatingmechanism. Through the arranged heating mechanism,
water vapor containing
phenol can be combusted, then the combusted
phenol is decomposed into water and
carbon dioxide, formed
water vapor performs heat exchange in the heat exchange mechanism, the heating mechanism can further heat
phenol-containing liquid entering a heating chamber, the phenol-containing liquid is vaporized and then conveyed intoa
combustion chamber through the air conveying mechanism to be combusted, water in a water guide
pipe can be preheated through the arranged preheating mechanism, and a large amount of water can be saved.
