设计了载乙醇活性炭微波解吸的实验流程。采用近似法测定载乙醇活性炭微波解吸的出口浓度曲线,对微波解吸的分离过程进行了分析。实验结果表明,中期乙醇出口浓度高于前后期;在320W微波功率下,90s即出现乙醇出口浓度的最高峰值;在680W微波功率下,60s即出现乙醇出口浓度的最高峰值;质量分数4%的低浓度乙醇水溶液经两次活性炭吸附-微波解吸循环后,乙醇出口质量分数的峰值可达94%以上。
The experimental process of carrying ethanol desorption by microwave was designed. The approximation method was used to determine the outlet concentration curve of ethanol desorption by microwave, and the separation process of microwave desorption was analyzed. The experimental results show that the medium-term ethanol export concentration is higher than the previous period; under the microwave power of 320W, the highest peak of the ethanol export concentration appears at 90s; at the microwave power of 680W, the highest peak of ethanol export concentration appears at 60s; the mass fraction of 4% Low concentration aqueous ethanol solution after two activated carbon adsorption - microwave desorption cycle, the mass fraction of ethanol export peak value of up to 94%.
