摘要
为了提高高压窄脉冲电源／反应器系统的能量效率和能量利用率，通过消去严重的电磁干扰，精确测得电源各部分的电参数．对电源／反应器系统加以改进，有效地提高了电源效率达７０％～８０％；能量利用率也得到显著的提高．测试结果证实了该过程的可行性．对初始浓度为０．２‰的ＮＯ＿ｘ，当ＮＯ脱除率达６０％～７０％时，总输入反应器能量为３Ｗ·ｈ／ｍ￣３，对ＮＯ的能量利用率达５０～６０ｇ／（ｋＷ·ｈ）．改进后新颖电源具有许多特点：回路简单、自带基压、可调电压范围宽等．
In order to raise the power efficiency and energy yield of a narrow pulse high voltagegenerator/reactor system,the authors have removed serious electromagnetic disturbance,andobtained accurate electric parameters of all parts of the generator.On the bases,the generator/reactor system has been improved effectively so that the power efficiency is up to 70%～80%andthe energy yield is raised greatly too.The test results have confirmed the feasibility of theprocess.Under an initial concentration of 200×10￣(-6)NO_x/Nm￣3,the NO removal efficiency is of60%～70%at energy input to gas of 3 W·h/Nm￣3.The resulting energy yield for NO is up to50～60 g/(kW·h).In addition,the novel generator has many characteristics,such as asimpler circuit,a self-imposed de-bias voltage,a larger range of pulse peak voltage,etc.
