摘　　要：在自行研制的气化 焚烧装置上进行一系列的相关实验 .通过系统的实验来研究不同工况下污泥气化焚烧后烟气中SO2 和NOx 的排放特性 ,并在实验基础上结合相关理论知识对其进行分析 ,为工业化应用提供参考 .实验表明 ,焚烧后的NOx 和SO2 的排放浓度较低 .标准状况下 ,NOx 的最高排放浓度为 2 43 .75mg/m3 ,SO2 的最高排放浓度为 167.191mg/m3 ,均远低于国家规定的排放标准 ,表明气化 焚烧两段处理是一种洁净的污泥处理技术 。Gasified incineration is clean waste incineration technique. A series of experiments are taken in a self-make gasification and combustion two-stage furnace. Research has been made on the emission characteristics of SO2 and NOx of sewage sludge in the gasifier under different circumstances (such as temperatures, gasification agents) through the systematic experiments. Based on the experiments analysis has been made with combination of related theories, which provides references for industrial application. Experiment results show that after incineration the emission density of NOx and SO2 is comparatively low. Under standard condition the highest density of NOx and SO2 are 243.75 mg/m3 and 167.19 mg/m3, which are both far below the emission standard regulated by our nation. It is proved that gasification and incineration two-stage treatment is a clean sewage sludge treatment technique and has a practical value.
