| 中文摘要: |
| 针对工业生产过程产生的有机废气，探究利用催化燃烧—等离子体降解有机废气的机理与工程应用的可行性。实验室研发了一套催化燃烧—等离子体装置，催化燃烧装置在1.5 L/min气体流量下，以纳米Fe2O3、纳米V2O5、MnO2为混合催化剂，在200~400 ℃下进行催化燃烧，停留8 s，等离子体装置在放电电压16 kV，停留10 s，该废气处理装置可使苯、甲苯和二甲苯的降解率分别达到95.1%、96.8%、97.2%，实现了废气的达标排放。 |
| 英文摘要: |
| In view of the volatile organic waste gas produced in the industrial production process, the feasibility of mechanism and engineering application is explored by using catalytic combustion-plasma to degrade organic waste gas. A catalytic combustion-plasma device has been developed in the laboratory. Under 1. 5 L/min gas flow rate, the catalytic combustion device takes the materials such as ferric oxide, manganese dioxide and vanadium pentoxide as catalysts. The catalytic combustion was performed at 200~400 ℃ temperature for 8 s. The waste gas treatment device can bring the degradation rate of benzene and xylene to 95% and 97% respectively at the discharge voltage 16 kV for 10 s. The waste gas can reach the standard of discharge. The device can be used as a new process for solving the problem of the pollution of volatile organic waste gas. |
