Zhao Fei，Sun Guogang，Peng Renjie, Liu Jianxin
The volatilization characteristics of ClO
2 solution were investigated using a self-made laboratory bubbling reactor. The effects of temperature, bubbling flow and concentration of ClO
2 solution on the volatilization rate of ClO
2 solution were studied. The results show that ClO'
2s volatilization is enhanced with increasing of ClO
2 solution concentration, bubbling flow and temperature. However, when the mass concentration of ClO
2 in solution is very low, the temperature has little effect on the evaporation rate. The relationship between volatilization and concentration of ClO
2 solution is linear. Based on the experiments, the correlation model of the concentration of ClO
2 solution attenuation with time is established: c=c
0e
-kt, the correlation of the volatilization rate coefficient of ClO
2 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 ClO
2 solution in the bubble reactor.
