High efficiency ozonizer for high quality water treatment

在本研究中，我们使用双放电产生的扩散辉光放电来改善臭氧制冷的效果。在这种方法中，电晕二次电荷发生在阴极和触发器之间的空隙中，触发器电极上覆盖着置于阴极凹槽中的聚四氟乙烯玻璃。实验采用空气(0_2/N_2混合气体)在常压下进行，所有实验的烟道放电校正频率均为I{HZ}。实验测得的最大臭氧浓度约为150ppm，平均臭氧产量约为400{go_y/kwh}，远高于典型臭氧产量约100{go_y/kWh}。在大容量储能条件下，电容器中的积聚能向主放电的能量转移效率约为40~50%。为了扩大臭氧的应用领域，高效的臭氧生成是首要问题。一种双次放电的方法，其中…更多的氢在大气压下产生扩散辉光放电，在本研究中使用。该方法与静默放电法、表面放电法等常规方法相比，具有较大的放电量。因此，我们期望通过其排放量获得更高的浓度和高效的臭氧生成。采用Au0_2/N_2混合物(空气)作为臭氧生成的原料气体，并将所有测量结果调整为2.0{L/分钟}。要获得扩散辉光放电，要求外加电压的快速上升时间大于0.8kV/ns，这一值与前人的研究结果吻合得很好。臭氧产生浓度随放电重复频率的增加而增加，当放电功率为1.4{W}时，产生的臭氧浓度最大可达550{ppm}。所有测量的平均臭氧产量为95-110{Go_3/kWh}。在旋转电极的情况下，由于出现了电弧，沉积功率的极限为1.2-1.4{W}。结果表明，臭氧浓度升高了约20%，旋转电极的放电起始电压值较小，旋转电极的放电条件较好。较少

In this research, a diffusc glow discharge generated by a double discharge us used to improve the etlicicucy of the ozone geueration. ln this method, corona dilischarge occuures in space between the cathode and the trigger electrnde covered with Pyrex glass tithe which is set in groove on the cathode. Much initial electrons are getuerated around the cathode.In present research, expermenuts were done using air (0_2/N_2 mixture) at atmospheric pressure and flue discharge recpctition frequency was I {Hz} for all expeariments. The maximnn ozone couicentration gencuated by that exjueriment was about 150 {ppm} The averange ozone yield was about 400{gO_y/kwh} that is much higler than the typical yield, about 100{gO_y/kWh}. The efficiecy of energy transfer from stoned energy in capacitor C_<"*"> to the main discharge was about 40 - 50 {%} at large stored energy.To expand the field of ozone application, efficient ozone generation is the most important problem. A double discharge in methed, whic … More h generates diffuse glow discharge at atmospheric pressure, is used in the present researchi. This methed has a larger discharge volume comparing with one of conventional methed, such as silent discharge, surface discharge and so on. Thus we expect that it is possible to get a higher concentration and to be efficient for ozone generation due to its discharge volume.Au 0_2/N_2 mixture (air) was employed as a raw gas for ozone gencration and adjusted at 2.0 {l/min} for all measurements. To get the diffuse glow discharge a rapid rise time over 0.8 {kV/ns} was required for the applied voltage arid this value gave good agreement with that obtained in preyious investigations. The generated ozone concentration increasad with, discharge repetition frequeucy and at 35 {Hz} where the deposited power of 1.4 {W}, the maximum generated ozone concentration of about 550 {ppm} was obtained. The mean ozone yield was 95 - 110 {gO_3/kWh} for all measurements. The limit of deposited power was 1.2 - 1.4 {W} due to the appearance of arcing.In the case of the rotating electrode. about 20% higher ozone concentration has been the outcome.The value of the discharge initiation voltage has been smaller for the rotating elect rode.Discharge conditions have been better in the case of rotating electrode.
