【摘要】 采用高频放电法对甲醛去除性能进行了研究.主要考察了甲醛去除率与电源施加电压、放电电流和电源频率之间的关系,并对无填料反应器及加有钛酸钡和亚硝酸钠填料的反应器对于甲醛的去除效率进行了对比实验,结果表明,甲醛的去除率随着电源施加电压、放电电流和电源频率的提高而提高;在相同条件下,反应器有填料比无填料对甲醛的去除率高,填加有钛酸钡填料的反应器比加有亚硝酸钠填料反应器对甲醛的去除率高.更多还原

【Abstract】 Decomposition of formaldehyde with high-frequency discharge plasma was studied in the paper. The relationships between formaldehyde removal efficiency and applied voltage,discharge current,power supply frequency were mainly investigated.The effect of non-filling,sodium nitrite filling and barium titanate filling were also compared.The experimental results showed that the removal efficiency of formaldehyde increased with increasing applied voltage,discharge current and power supply frequency.Under the same conditions,the reactor with filling had higher removal efficiency than the reactor without filling. Furthermore,the reactor with barium titanate filling had higher removal efficiency than the reactor with sodium nitrite filling.更多还原
