The invention provides a waste residue and waste gas recovery treatment system for an industrial deslagging roller. The recovery treatment system comprises a support mounting base plate, a support column, a waste residue recovery box, an electrical control box, a suction hood, a support cross rod, an exhaust fan, a gas guide pipe, a water storage tank, a slag charge prevention waste gas recovery screen plate structure, a waste residue crushing plate structure, a backflow dust suppression pipe structure, a waste gas treatment tank structure, a waste gas treatment spraying coil pipe structure, awaste residue filtering hopper structure, a water guide pipe and a submersible pump. The recovery treatment system is specially designed for the industrial residue discharge roller, the air suction hood is arranged on the upper portion of the industrial residue discharge roller, and the waste residue recovery box is arranged on the lower portion of the industrial residue discharge roller and usedfor conducting recovery treatment on waste residues and waste gas; in addition, waste residues of the industrial residue discharging roller can be effectively crushed, filtered and recycled, the treatment effect on the waste residues is better, and the recycling efficiency is higher; meanwhile, waste gas is subjected to spraying treatment and purification, so that practicability is high, and popularization is facilitated.
