| 中文摘要 |
| 以低浓度、大风量、含无机物、尘粒和油分等成分的复杂工业有机废气为对象,进行复合吸收净化技术的研究,从吸收机制初步探索,对净化设备、工艺流程及工程应用分别进行了探讨.分别以3种不同的表面活性剂溶液为复合吸收剂,考察其处理含甲苯和醋酸丁酯废气的净化效果,结果表明降低复合吸收剂的表面张力,有利于甲苯和醋酸丁酯的去除率.针对复杂工业有机废气,开发高效吸收设备,集合了水膜、旋流板和填料3种吸收净化装置的优点于一体,具有结构简单、体积小、防堵塞及多级高效吸收传质的优势.工艺流程以吸收技术为主,整合了加热吹脱、燃烧和厌氧等工艺,最终使废气和吸收尾液达标排放.该技术已在制造、喷涂等多家企业的工程上应用. |
| 英文摘要 |
| Complicated industrial organic waste gas with the characteristics of low concentration,high wind volume containing inorganic dust and oil was employed the research object by complex absorption. Complex absorption mechanism, process flow, purification equipment and engineering application were studied. Three different surfactants were prepared for the composite absorbent to purify exhaust gas loaded with toluene and butyl acetate, respectively. Results show that the low surface tension of the composite absorbent can improve the removal efficiency of toluene and butyl acetate. With the advantages of the water film, swirl plate and fill absorption device, efficient absorption equipment was developed for the treatment of complicated industrial organic waste gas. It is with superiorities of simple structure, small size, anti-jam and high mass transfer. Based on absorption technology, waste gas treatment process integrated with heating stripping, burning and anaerobic and other processes, so that emissions of waste gas and absorption solution could meet the discharge standards. The technology has been put into practice, such as manufacturing and spraying enterprises. |
