摘要

为探究以海水作为脱硫剂在喷射鼓泡塔上的脱硫特性

通过改变废气流量、海水温度、浸液深度、SO2进口浓度和O2浓度等操作参数

在自主设计和搭建的喷射鼓泡塔实验平台上进行了船舶模拟废气的脱硫实验。实验结果表明:在喷射鼓泡塔上

海水对SO2的吸收容量为3.682 mmol·L-1

约是去离子水的3.92倍;脱硫效率随废气流量、海水温度和SO2进口浓度的升高而降低

随浸液深度和O2浓度的升高而升高

与脱硫时间呈线性下降关系。液相总传质系数随废气流量和海水温度的增加而增加

其中废气流量的影响幅度较小

仅为3.16%。增加O2浓度可显著提高海水对SO2的吸收容量

O2浓度从0%增至12%时

海水的吸收容量从3.682 mmol·L-1增至7.463 mmol·L-1。

Abstract

In order to study the desulphurization properties of seawater with jet bubbling reactor

experimental researches on SO2 removal from simulated marine waste gas were investigated in a self-designed jet bubbling reactor. The parameters influencing desulphurization efficiency

such as waste gas flow

seawater temperature

immersion depth

inlet concentration of SO2 and O2

were examined. Results showed that the absorption capacity of seawater scrubbing SO2 was up to 3.682 mmol·L-1 about 3.92 times that of deionized water. The desulphurization efficiency decreased with the increase in waste gas flow

seawater temperature and inlet SO2 concentration while it increased with increasing immersion depth and inlet O2 concentration. Desulphurization efficiency reduced linearly over desulphurization time. Increasing waste gas flow can increase total liquid phase mass transfer coefficient by 3.16%

which was less than that of seawater temperature. The absorption capacity increased significantly with increasing inlet O2 concentration. It increased from 3.682 mmol·L-1 to 7.463 mmol·L-1 as the inlet O2 concentration increased from 0% to 12%.
