硫磺制酸装置中升华硫产生原因及控制

Cause analysis and control of sublimation sulfur in sulphuric acid plant

硫磺制酸生产中因硫磺氧化反应不完全极易气化变成升华硫,通过产生原因逐一分析,对应采取控制氧硫比、稳定炉温、提高自动控制水平、做好员工操作培训等措施,生产效果明显。

In sulfuric acid production,it,s easy to gasify into sublimated sulfur due to incomplete oxidation reaction of sulfur in the production of sulfuric acid. Through the analysis of the causes one by one,corresponding measures such as controlling the ratio of oxygen and sulfur,stabilizing the furnace temperature control,improving the automatic control level,and doing a good job in staff operation training have been taken. The control effect is obvious.
