Developemtn of an ozonizer using a ceramic honeycomb

为了提高臭氧在电力消耗中的产出率，研究了利用金属氧化物的一些表面效应的尝试。第一次尝试是通过在细导线之间放电，将电极插入陶瓷蜂窝中，并在导线周围流动氧气。在这种情况下，由金属电极、电介质、放电间隙和金属电极组成的普通臭氧发生器的臭氧产率小于1。系统地观察了将金属氧化物放入普通型臭氧发生器放电间隙时的臭氧产率。通常情况下，实验结果会有很大的分散，有时我们得到一种金属氧化物的臭氧产率很高，而下一次我们却找不到同样材料的任何积极影响。但经过大量的实验工作，我们得出以下结论：放电间隙中某些金属氧化物对臭氧的生成有负面影响，FeO、Cuo、ZnO、V205、MoO3和WO3比没有金属氧化物的放电间隙中臭氧的生成率更高。其中，V205和MoO3的等摩尔混合物臭氧产率最高。通过求解boltzaman方程可知，在最适宜的电场强度/气体压力条件下，约85%的电子能量用于臭氧的产生。

To improve the production yield of ozone per the electric power constumption, attempts using some surface effects of metal oxides have been investigated.The first attermpt has been made by discharging between fine wires electrods which were inserted into a ceramic honeycode and flowing oexgen around the wires. In this case, the ozone yield was less than one for the ordinary ozonizer which consists of the metal electrode, dielectric, discharge gap and metal electrode. The ozone yield in the condition that the metal oxide was put into the discharge gap of the oedinary type ozonizer was obaserved systematically. Generaly, there was a large scatter of experimental results, sometimes we got very high ozone yield for a mewtal oxide, and next time we could not find any positive effiect for the same material. However after a lot of expreimental works, we have the following conclusion, some metal oxides in the discharge gap have negative effect for ozone production, and FeO , Cuo, ZnO, V205, MoO3, and WO3 inctrase the ozone yield than one for without metal oxide in the discharge gap. Especially, the equi-mol-mixture of V205 and MoO3 shows the largest ozone yield.It mas clarified by solvingBoltzaman equation that about 85% of electron enrgy is used for ozxone preduction in the most sutable condition of applied field strength/ gas pressure.
