为了提高放电等离子体水处理技术中的能量注入及处理效果,设计出一种耦合谐振放电电路,将脉冲电源产生的脉冲波形转化为耦合谐振波形,并将其产生的耦合谐振放电等离子体用于双反应器中罗丹明B溶液的降解,为同时对双反应器中的有害物质进行高压脉冲放电等离子体降解提供了一种放电波形支持;并采用分光光度法检测罗丹明B溶液的浓度。结果表明,耦合谐振放电可显著提升罗丹明B溶液的降解效果。放电降解60 min后,双反应器中的溶液降解率在不同放电电容配比下均可达到90%以上。耦合谐振放电注入反应器中的能量至少是无耦合谐振放电的7倍,其能量注入效率更高。此外,调整放电电路中的电容值可分别改变双反应器中注入的能量,进而影响到降解效果;反应器中溶液电导率越大,放电现象越明显。
In order to improve the energy injection and treatment effect in the discharge plasma water treatment technology, a coupled resonant discharge circuit is designed to convert the pulse waveform generated by the pulse power into a coupled resonant waveform and use the coupled resonant discharge plasma generated by the coupled resonant discharge plasma The degradation of rhodamine B solution in the dual reactor provided a support for the discharge waveform for simultaneous decontamination of harmful substances in the double reactor by pulsed discharge plasma. The concentration of rhodamine B solution was measured by spectrophotometry. The results show that the coupling resonance discharge can significantly enhance the degradation of rhodamine B solution. After 60 min of discharge degradation, the solution degradation rate in double reactor can reach more than 90% under the different discharge capacity ratio. The energy injected into the reactor by the coupled resonant discharge is at least seven times that of the uncoupled resonant discharge, and its energy injection efficiency is higher. In addition, adjusting the capacitance of the discharge circuit can change the energy injected into the dual reactor, thereby affecting the degradation effect; the greater the solution conductivity of the reactor, the more obvious the discharge phenomenon.
