大型硫磺制酸装置塔前塔后设置风机的能量分析

Energy Analysis for Installation of Blower Fan Before and After the Tower in A Large-scaled Sulfur-burning Sulfuric Acid Plant

以800kt/a硫磺制酸装置为例,对风机设置在干燥塔前后两种不同位置的能量平衡进行了分析,认为设置在干燥塔后风机的热量回收利用率高。

By taking the 800 kt/a sulfur-burning sulfuric acid plant as the example,the energy balance for the blower fan installed before and after the drying tower is analyzed,and the conclusion is come to that by installing the blower fan after the drying tower,it will offer higher utilization of the recovered heat.
