摘要
在特制的多层立式振动流化床干燥器上,研究了停留时间、加热温度、加热气量、振动频率和振幅等因素对尿素氰酸缩聚反应生产三聚氰酸的影响。结果表明:当加热温度大于220℃时,停留时间是影响反应的主要因素,此时尿素转化率的变化与传统的干燥速率曲线类似。根据实验结果得出相应的经验公式,可用于反应器的设计计算。
The process for the synthesis of cyanuric acid from urea cyanurate was studied in a special multilayer vibration fluidized bed.The effects of residence time,temperature,fluidizing velocity,vibrational frequency and vibration amplitude on the conversion of urea to cyanuric acid were investigated.The residence time was found to be the main factor affecting the reaction.The instantaneous decomposition rate curve of urea was similar to that of the drying process.Based on the experimental data,an empirical equation was developed for designing the reactor.
