氧气沿面放电臭氧合成机理

提出了一种氧气沿面放电过程中臭氧合成的"双区模型",即氧分子离解区和与之分离的臭氧形成区.臭氧的产生率由离解区氧原子的产生效率和形成区氧原子转化为臭氧的效率决定.沿面放电中臭氧的产生率低电场时随电场升高而增大,高电场时随电场增大而减小.在氧气的击穿电场附近和低温条件下可以获得较高的臭氧合成效率.

Ozone Synthesis in Oxygen in Surface Discharge

A two-region-reactor model is presented to investigate the ozone synthesis in the surface discharge in oxygen, in which the production of oxygen atom and ozone is assumed to take place in two separated regions, i.e. the dissociation and the formation regions. The calculation results show that the ozone generation is determined by the generation of the oxygen atom which is only related to the discharge process in dissociation region, and by the transformation ratio of oxygen atoms into ozone molecules which is determined by the three body reactions in the formation region. The ozone generation of the surface discharge type ozonizer increases as the reduced field increasing at lower field but decreases almost proportionally at higher field (or the applied voltage). A good efficiency of ozone formation can be obtained at moderate field and lower temperature during the surface discharge.
