[0002] At present, domestic RTO+rotor equipment basically adopts the structure of filter box+rotor+RTO+plate heat exchanger. The exhaust gas temperature in the tire and rubber industry is high. In order to reduce the exhaust gas temperature, the front-end treatment generally adopts a surface cooler. The cooling mode of the surface cooler is cooling circulating water.
