Papermaking waste gas deodorization and waste heat recovery integrated equipment

The invention discloses papermaking waste gas deodorization and waste heat recovery integrated equipment. Comprising an exhaust fan and a waste gas treatment tower, the waste gas treatment tower comprises an integrated shell and further comprises a waste heat recovery system, a spraying system, a demisting system and a reheating system from bottom to top, the spraying system comprises a spraying pipeline, a spraying nozzle, a liquid supplementing device, a liquid collector and a spraying liquid circulating device, and the liquid collector comprises a liquid receiving disc, an air distribution pipe and a rain cap. The air distribution pipe penetrates through the bottom of the liquid receiving disc so that waste gas can enter the spraying system from the waste heat recovery system, and the rain cap is arranged above the air distribution pipe so that spraying liquid cannot enter the air distribution pipe. The waste heat utilization efficiency is high, the waste gas cooling and dehumidifying effects are good, the
