摘　　要：采用蜂窝板式反应器与管状式反应器考察了氧化铝负载高锰酸钾(简写PM球)在模拟空间内氧化气态甲醛的效果,研究PM球降解甲醛的动力学规律。结果表明:PM球对甲醛的氧化反应过程符合一级反应动力学方程;当风量相同且PM球用量在1.25kg以上时,管状式反应器结构有利于氧化反应的进行。经处理后,模拟空间中的甲醛含量最快30min可以降至国家标准(0.1mg/m^3)以下。通过分析可知反应器的净化效果除了取决于氧化剂之外还与风机的风压有关。In this paper,two kinds of reactors,namely honeycomb plate reactor and tubular reactor respectively,in a simulated space with alumina-supported potassium permanganate(PM balls)were investigated,in order to evaluate their effects on oxidation of gaseous formaldehyde and the kinetics of how the PM balls can degrade formaldehyde.The experimental results showed that the oxidation reaction of formaldehyde with PM balls followed the first-order reaction kinetics equation.When the air volume was the same and the amount of PM balls was more than 1.25 kg,the tubular reactor structure facilitated the oxidation reaction.The formaldehyde content of the simulated environment could be reduced to 0.1mg/m^3 in the fastest 30 minutes after the reaction.It could be found with the analysis that the purification effect of the reactor was related to the wind pressure of the fan in addition to the catalyst.
