中文摘要
本文利用微波热处理法, 分别在大气和氮气气氛两种情况下快速再生了已经充分吸附SO2的颗粒状活性炭. 微波热处理过程中, 应用红外热成像技术, 采集了样品的一系列热图像, 直观显示了温度分布, 表明热处理的最高温度仅为300℃. 将再生产物用于模拟烟气脱硫实验, 结果表明大气气氛下, 微波再生活性炭的脱硫性能还不及原炭的一半; 换以氮气气氛隔绝空气后, 其脱硫性能提升到原炭的97%. 隔绝空气条件下的微波热处理再生法比传统热再生方法, 降低了处理温度、极大缩短了再生时间, 体现了高效、低能耗两大优势.
英文摘要
In this paper a typical commercial granular activated carbon which is fully SO2 adsorbed is regenerated by microwave heating under ambient atmosphere condition and nitrogen gas atmosphere condition, respectively. A series of thermal images of the sample are captured during the microwave heating with infrared thermography technology. It showed temperature distribution visually and the highest temperature is only 300℃. The product is used to simulate flue gas desulfurization(FGD) experiments. The results indicated that the desulfurization performance of the product under ambient atmosphere condition is less than half of the virgin activated carbon. While isolated from the air using nitrogen gas flow, it rises to 97% of the virgin activated carbon. Compared to conventional thermal regeneration, microwave thermal regeneration reduced the processing temperature and time. These revealed two significant advantages of the microwave thermal regeneration: high efficiency and low energy consuming.
