以江苏省如东县的危险废物焚烧处置工程为例，探讨了危险废物焚烧系统的工程原理和性能特点。结果表明：采用“回转窑+二燃室+余热锅炉+急冷塔+旋风除尘器+干式脱酸塔+布袋除尘器+湿式洗涤塔”工艺，回转窑温度控制在850℃左右，危险废物在回转窑停留的时间约60min；二燃室温度>1100℃，烟气在二燃室内的停留时间＞2s；余热锅炉出口烟气温度约为550℃；两级除尘、干法与湿法相结合的工艺，可实现危险废物的无害化、减容、减量处理，为其他工程应用提供了参考。%By taking the incineration disposal engineering of hazardous wastes in Rudong county of Jiangsu province as an example, the article probes into engineering principle and performance characteristics of hazardous waste incineration system, and provides references for the other engineering practice in the future.
