Experimental Study on Desulfurization and Denitration by Pulsed Corona Plasma

采用ns级脉冲电源对电晕反应器供电,电离烟气产生OH^(*)、H^(*)等活性自由基,可同时脱除SO_(2)、NO、Hg等污染物。该装置抽取燃煤电厂脱硫后实际烟气进行脱硫脱硝实验,并通过调整反应器极间距、极配形式、电源运行参数、装置运行工艺等手段,摸索脉冲等离子体脱硫脱硝的最佳极配形式和运行工况,提高脉冲电晕等离子体脱硫脱硝反应效率。

The corona reactor is powered by nanosecond pulse power supply,can ionize the flue gas and produce active radicals such as OH^(*) and H^(*),which could remove pollutants such as SO_(2),NO,Hg and so on at the same time.In this device,the actual flue gas after desulfurization tower from coal-fired power plants is extracted for desulfurization and denitration experiments.By the methods of adjusting electrode spacing,electrode configuration,operation parameters of the pulse power supply and the operation technology of this device,the optimal operation condition of this device is explored to improve the efficiency of desulfurization and denitration reaction by pulsed corona plasma.
