| 摘 要： | 对低温等离子体烟气脱硫技术中OH自由基发生装置的电极结构及放电特性进行了研究。得到电极结构的参数对放电特性的影响规律：放电电流随针对数增加和针直径的减小而增大．得到针间距理想值与针板间距的关系式．实验表明,在一定范围内,水蒸气从针电极喷出的速度对放电电流没有明显影响．并对大气压下不饱和水蒸气电晕放电中的OH自由基进行了发射光谱诊断．

| Abstract: | The electrode structure and discharge characteristics of the apparatus producing OH radicals for desulfuration from flue gas by non-thermal plasma have been investigated. The influence of electrode structure parameters to discharge characteristics has been defined: the discharge current increases with the number of nozzle-couples increasing and decreases with the nozzle-diameters increasing. The relation between the ideal space of nozzles and the space of nozzle-plate was obtained. Results show that in a certain scale, the flux of water vapor injecting into the reactor by the nozzles electrode has no obvious influence on the discharge current. In addition, OH radical has been diagnosed in atmospheric unsaturated water vapor corona discharge by optical emission spectroscopy. |
