The purpose of this research was to simultaneously evaluate the removal efficiency of acid gases and PAHs from the flue gas emitted by a laboratory incinerator. This flue gas contained dust, acid gases, organics and heavy metals. A spray dryer combined with a fabric filter was used as the air pollution control device (APCD) in this study. The operating conditions investigated included different feedstock additives (polyvinyl chloride (PVC) and NaCl) and spray dryer additives (SiO2, CaCl2 and NaHCO3). The removal efficiency for SO2 could be enhanced by adding inorganic additives, such as SiO2, CaCl2 and NaHCO3. The presence of PVC in the incinerator feedstock also increased the removal efficiency of SO2in the spray dryer. The improved removal of PAHs could be attributed to the addition of feedstock additives (PVC and NaCl) and spray dryer additives (SiO2, CaCl2 and NaHCO3).
本研究的目的是同时评估实验室焚烧炉排放烟气中酸性气体和多环芳烃的去除效率。该烟气含有粉尘、酸性气体、有机物和重金属。本研究采用喷雾干燥器与织物过滤器相结合的装置作为空气污染控制设备（APCD）。所研究的运行条件包括不同的原料添加剂（聚氯乙烯（PVC）和氯化钠）和喷雾干燥器添加剂（二氧化硅、氯化钙和碳酸氢钠）。添加无机添加剂（如二氧化硅、氯化钙和碳酸氢钠）可提高二氧化硫的去除效率。焚烧炉原料中PVC的存在也提高了喷雾干燥器中二氧化硫的去除效率。多环芳烃去除率的提高可归因于原料添加剂（PVC和氯化钠）和喷雾干燥器添加剂（二氧化硅、氯化钙和碳酸氢钠）的添加。
