摘要: 自行设计并制造了金字塔形微波谐振腔的炭化炉, 3个微波管从3个方向进行辐照,谐振腔内部增加了微波搅拌器,改变了微波辐照均匀性。双层微波防泄漏炉门设计,降低了微波泄漏的风险。经过应用研究表明,微波辐照功率 1 160 W,辐照时间 18 min,制得活性炭的亚甲基蓝吸附值 210 mL/g,为国家标准规定的活性炭一级品GB/T 13803.3-1999的1.75倍。在 680 W 条件下,微波辐照载苯酚废活性炭 5 min,可以获得亚甲基蓝吸附值为 110 mL/g 的再生活性炭,优于国家规定的二级品标准。

Abstract: The pyramid microwave carbonization furnace was designed and manufactured. Microwave was irradiated by three microwave tube from three directions. The furnace was equipped with a blender, which increase the uniformity in resonant cavity. The design of double microwave leakage protection furnace door reduces the risk of microwave leakage. The research results showed that under the microwave irradiation power 1 160 W and radiation time 18 min, the activated carbon has methylene blue adsorption value of 210 mL/g, which is 1.75 times higher than the specifications in the standerd of activated carbon grade A (GB/T 13803.3-1999). Under the irradiation power of 680 W and irradiation time 5 min, the methylene blue adsorption value of phenol containing waste activated carbon can reach 110 mL/g, which is better than the level two standard of China.

Key words: resonant cavity, microwave, activated carbon
