【摘要】 把氟利昂(以CFC-12为研究对象)、液化石油气(LPG)、空气和水蒸汽混合后燃烧,氟利昂被分解成HF,HC l和CO2等,用NaOH溶液对其分解产物进行吸收,初步实现了氟利昂的无害化处理.结果表明过剩空气系数为1.2,一次空气量占空气总供给量的30%为最佳燃烧条件.水蒸汽和高温是氟利昂分解的重要条件,选择水蒸汽通入量为氟利昂通量入量的3倍,氟利昂的分解率随反应温度的升高而增大.更多还原

【Abstract】 By combusting the premix of CFCs(CFC-12),LPG,air and water vapour,CFC-12 is decomposed to HF,HCl and CO2.With these decomposition products being absorbed by sodium hydroxide solution,CFC-12 is thus harmlessly treated.It is also shown through the results that the best combustion condition is that coefficient of surplus air is 1.2 and that the rate of once air is 30%.High temperature and oversupply of water vapour are key factors.The best rate of water vapour to CFC-12 is 3∶1.The decomposition efficiency increases along with combustion temperature.更多还原
