摘要/Abstract

摘要： 利用自制的实验室小型鼓泡床反应器探究了ClO₂溶液的挥发特性；考察了温度、鼓泡气量和ClO₂质量浓度对ClO₂溶液挥发速率的影响。实验表明，ClO₂质量浓度、鼓泡气量、温度越高，ClO₂的挥发越大，鼓泡气量对挥发速率的影响大于温度；但在溶液中，ClO₂质量浓度很低的情况下，温度对挥发速率的影响较少；ClO₂的挥发速率与溶液的ClO₂质量浓度基本呈线性关系。结合实验数据，构建了鼓泡条件下ClO₂溶液质量浓度随时间衰减的关联模型c=c₀e^-kt，并得出了ClO₂溶液挥发速率系数的关联式：k=2.152 5×10^-5θ+3.427 6×10^-4Q-7.599 7×10^-4，模型计算值与实验值吻合较好，可用于鼓泡床中ClO₂溶液挥发速率的分析计算。

Abstract: The volatilization characteristics of ClO₂ solution were investigated using a self-made laboratory bubbling reactor. The effects of temperature, bubbling flow and concentration of ClO₂ solution on the volatilization rate of ClO₂ solution were studied. The results show that ClO'₂s volatilization is enhanced with increasing of ClO₂ solution concentration, bubbling flow and temperature. However, when the mass concentration of ClO₂ in solution is very low, the temperature has little effect on the evaporation rate. The relationship between volatilization and concentration of ClO₂solution is linear. Based on the experiments, the correlation model of the concentration of ClO₂ solution attenuation with time is established: c=c₀e^-kt, the correlation of the volatilization rate coefficient of ClO₂ solution is also obtained: k=2.152 5×10^-5θ+3.427 6×10^-4Q-7.599 7×10^-4. The model calculation is in good agreement with the experiment results, and can be used to calculate the volatilization rate of ClO₂ solution in the bubble reactor.
