摘要
吸附了乙醇气体的活性炭纤维,采用微波辐照法进行解吸及再生得到高浓度乙醇,为回收利用印刷废气中的乙醇提供了一条有效途径。研究了微波功率、辐照时间、活性炭纤维量、氮气流量等对乙醇解吸的影响。结果表明,在微波功率528 W、载气流量1.4 m3/h、活性炭纤维质量3 g、辐照时间180 s的条件下,乙醇的浓度可达到95.6%。
In order to recycle the ethanol in waste gas from printing industry, the method of microwave de- sorption of ethanol under nitrogen condition. The influences of operating conditions on ethanol desorption such as the microwave power, irradiation time, activated carbon fiber dosage and nitrogen flow rate were investigated. The results show that under the conditions of microwave power 528 W, nitrogen flow rate 1.4 m3/h, irradiation time 180 s,and the outlet concentration of ethanol is 95.6% with 3 g activated carbon fiber.
