脉冲流光放电臭氧高效发生过程中能量高效转换与传热机理

Excessive energy consumption of ozonizer restricts the application of multi-pollutants simultaneous removal techonology from flue gas by combined ozone oxidation and chemical scrubbing, and industrialization of ozone oxidation technology is also confined. In order to increase the ozone production efficiency and decrease the power consumption, several research teams wordwide, including project applicants, have explored plused streamer discharge. Their research results show that ozone could be generated efficiently by plused streamer discharge. However, these investigations just base on superficial phenomenon study. This project, basing on the two core of electric energy conversion and heat transfer in process of ozone generation, will discover the electric energy conversion characteristics and heat transfer characteristics of ozone generation via plused streamer discharge through the method of numerical calculation, numerical simulation combing with experiment. And then, the energy conversion and transfer mechanism of ozone generation via plused streamer discharge will be revealed from these. The key factors and optimum conditions will be confirmed also. At the same time, the basic study of this project provides new research approach for the research of energy conversion and heat transfer characteristics of ozone generation in low temperature plasma. These will have vital meaning to increasing the ozone production efficiency and promoting the industrialization of ozone oxidation technology.
