吸收塔中亚硫酸钙氧化是石灰石/石灰湿式脱硫工艺中的一个重要化学过程。脱硫系统中氧化不充分容易导致结垢和堵塞，强制氧化对脱硫系统安全运行至关重要。针对目前强制氧化的氧化风机系统存在的问题，开展了高效低耗的射流氧化工艺研究，该工艺取消了氧化风机和吸收塔搅拌器，可大大降低脱硫装置系统投资和运行维护费用。介绍了射流氧化原理及工艺流程，设计了射流曝气器并通过CFX模拟计算确定了在实验条件下射流曝气器的最佳安装高度。

Oxidation of calcium sulfite is an important chemical processes in limestone-gypsum WFGD. Incompletely oxidization causes fouling and clogging and forced oxidation is essential for the security of WFGD. Aiming at problems of the oxidation fan system, this paper develops a new jet oxidation process, which is efficient and low consumption, abolishes the oxidation fans and absorber agitators. The new process can greatly reduce the investment, operation and maintenance costs. This paper introduces the principle and process of jet oxidation, designs Jet aerator and identifies optimal mounting height under experimental conditions by CFX model.
