Transport and Focus of Pulse Intense Electron Beam and its Application for Decomposition of Environmental Pollution Gas

进行基础研究，以开发一种新的干燥工艺，作为一种由脉冲密集电子束执行的气体处理装置。从纯硝基或氧混合硝基气体中提取的NO-D2 x-D2基本数据（流动气体模型）是通过使用N-D2 x-D22-O-D22-D2测量设备（NAA-7000）在1997年购买的赠款中。After generation of N radicals in pure n\gen by the injection of pulse high current electron beam （[less than or equal] 160 keV，140 A，2 A/cmイD12イD1，700 ns，12. 6 J/\）， NO was reduced to NイD22イD2 and OイD22イD2。去除无离子D2 x-D2的能量效率相当于连续电子束或2 - 3次的大值（500 - 900 nmol/J），而不是气体单元体积、初始无离子浓度和电子束功率的最佳条件。在流动气体模型中， OH radicals在400纳摩尔/J的效率下被清除为氢氧化物D2 x，当水被添加到混合气体中时。NO-D2x-D2 was also removed at higher efficiency when the inner wall of the gas cell was covered with the wet cloth. By addition of NHイD23イエD2 only， NOイD2xイエD2 was also removed。一个新的高密度电子束反应器被认为是在一个电子束被自磁场产生的大电流压缩和传输的。作为这样一个方案的初步实验，脉冲电子束被强外部磁场压缩和传输，并被注入NO（=200 ppm）/N-D22-D2气体。不，D2 x D2被删除了50%，被3次击中。这些结果建议，即脉冲密集电子束有可能成为一种新的气体治疗设备。

Fundamental research for developing a new dry process of flue gas treatment device by the pulse intense electron beam was performed. Basic data on the NOィイD2xィエD2 removal from pure nitrogen or oxygen mixed nitrogen gas (model flue gas) were experimentally obtained by using the NィイD2xィエD2-OィイD22ィエD2 measuring device (NOA-7000) that was bought by the Grant-in-Aid in 1997. After generation of N radicals in pure nitrogen by the injection of pulse high current electron beam (【less than or equal】160keV, 140A, 2A/cmィイD12ィエD1, 700ns, 12.6 J/shot), NO was reduced to NィイD22ィエD2 and OィイD22ィエD2. The energy efficiency of NOィイD2xィエD2 removal was equal to that for the continuous electron beam or 2 〜 3 times larger value (500 〜 900 nmol/J) than that at optimized conditions of the gas cell volume, initial NO concentration and electron beam power. In the model flue gas, OH radicals removed NOィイD2xィエD2 at the efficiency of 400 nmol/J when the water was added to the mixture gas. NOィイD2xィエD2 was also removed at higher efficiency when the inner wall of the gas cell was covered with the wet cloth. By addition of NHィイD23ィエD2 only, NOィイD2xィエD2 was also removed. New high current density electron beam reactor was considered in which the electron beam was compressed and transported by self magnetic field generated by its large current. As a preliminary experiment of such a scheme, the pulse electron beam was compressed and transported by strong external magnetic field and injected into NO(=200 ppm)/NィイD22ィエD2 gas. NOィイD2xィエD2 was removed as high as 50% by 3 shots. These results suggest that the pulse intense electron beam has a possibility to be a new gas treatment device.
