Abstract

Toxics in alcohol have been strongly negative affected to human life in large area, especially the alcohol with the huge poison inside like methanol, aldehyde, furfural, acidity$\dots$ It killed a thousand people, in developing countries particular and in the world general. The disadvantages of the currently state are the using treatment systems with low treatment efficiency, costly and unstable due to using microbiological, biochemistries, combining physical chemistry method. In this study, the treatment alcohol from laboratory using dielectric barrier discharge (DBD) at low temperature and at atmospheric pressure was designed and developed to solve the above disadvantages. An 800ml/h treatment system was completed and assembled. In order to prove the stability of the processing system, before and after treating, alcohol samples were collected and measured with methanol, aldehyde, furfural, acidity by the Quality Assurance and Testing Center. The treating duration and applied voltage were studied. The results show that with high discharge density, the toxics in alcohol rapidly increased due to oxidation reaction. However, at high applied voltage and long treating duration the treatment efficiency increased. The results also showed that treatment efficiency reached to 60-80% and match The Vietnamese Standard 7043: 2013 prepared by the TCVN/TC/F9 TCVN National Standardization Technical Committee, the Directorate for Standards and Quality, Ministry of Science and Technology
常压介质阻挡放电(DBD)陈酒模型的建立
酒精中的有毒物质已经在很大范围内对人类的生活产生了强烈的负面影响,特别是含有巨大毒性的酒精,如甲醇、醛、糠醛、酸度$\dots$,在发展中国家和世界范围内,它杀死了成千上万的人。目前的缺点是由于采用微生物、生物化学、物理化学相结合的方法,使用的处理系统处理效率低、成本高、不稳定。本研究针对上述缺点,设计开发了低温常压介质阻挡放电(DBD)处理实验室酒精的工艺。完成并组装800ml/h处理系统。为了证明处理系统的稳定性,在处理前后,由质量保证与检测中心采集酒精样品,测定甲醇、醛、糠醛、酸度。对处理时间和施加电压进行了研究。结果表明,在放电密度较大的情况下,由于氧化反应,乙醇中的毒性物质迅速增加。在高外加电压和长处理时间下,处理效率提高。结果表明,处理效率达到60-80%,符合国家科技部标准与质量局TCVN/TC/F9 TCVN国家标准化技术委员会制定的越南标准7043:2013
