小型二次发射电子枪气体处理系统的研制
Development of compact gas treatment system using secondary emission electron gun
摘要：
利用放电或电子束的低温等离子体技术是去除环境污染物的有效方法。特别是电子束可以有效地去除污染物，因为高能电子可以容易地产生许多对去除污染物有用的自由基。我们已经开发了一个紧凑的100千伏二次发射电子枪应用于氮氧化物的去除。该器件具有体积小、束宽均匀等优点。此外，与辉光放电或场发射控制阴极枪相比，该装置具有良好的高重复频率脉冲工作能力，且易于控制。在本研究中，氮氧化物的去除特性进行了研究下增加枪电压，不同的脉冲电子束参数，如电流密度和脉冲宽度以及气体流量。实验结果表明，与其他高能电子束和放电处理相比，该方法具有更好的NOx去除效率。
英文摘要：
It is well known that the non-thermal plasma processes using electrical discharge or electron beam are effective for the environmental pollutant removal. Especially, the electron beam can efficiently remove pollutant, because a lot of radicals which are useful to remove pollutant can be easily produced by high-energy electrons. We have developed a compact 100kV secondary emission electron gun to apply NOX removal. The device offers several inherent advantages such as compact in size, wide and uniform electron beam. Besides, the device offers good capability in high repetition rate pulsed operation with easy control compared with glow discharge or field emission control cathode guns. In present study, the NOX removal characteristics have been studied under the increased gun voltage, varied pulsed electron beam parameters such as current density and pulse width as well as gas flow rate. The experimental results indicate a better NOX removal efficiency comparing to other high-energy electron beam and electrical discharge processing.
