Abstract

The invention discloses a waste gas treatment device of a pre-roll-coating aluminum roll production line. The waste gas treatment device of the pre-roll-coating aluminum roll production line comprises a combustion system, a heat exchange system and a spray drying system. The spray drying system comprises a spray drying tank, a clean air outlet, an induced draft fan and an exhaust flue. The heat exchange system is arranged on one side of the spray drying system and comprises a heat accumulation chamber, a primary heat exchanger and a secondary heat exchanger. The combustion system is arranged on one side of the heat accumulation chamber and comprises a combustion engine, a mixer, a combustor and a fireproof plate. By adoption of the primary heat exchanger and the secondary heat exchanger, waste heat generated after combustion of waste gas is reused, on the one hand, preheating is conducted before combustion of the waste gas, so that the combustion efficiency of the waste gas is improved, and on the other hand, heat is provided for the spray drying tank, consumption of energy is reduced, the utilization rate of energy is improved, and protection on the environment is achieved.
