以节能降耗为目的,在多级喷动流态化烟气脱硫技术示范工程上,对其系统流动和阻力特性进行了优化研究.结果表明:入口均流装置采用布置1块竖直导流板具有明显优越性;多级喷动塔体结构,可明显降低塔体高度,使其系统负荷适应性达到40%-100%;脱硫塔一级塔体呈现中心流速高边壁流速低的规律,中心气速约10 m/s,边壁气速约6 m/s,二级塔体上部区域流速峰值明显向脱硫塔出口侧倾斜;新型全骨栈桥快速分离装置阻力损失较小,约占系统阻力损失的23.7%;入口段阻力损失所占份额最大,约为51%,为降低能耗还需对其作进一步优化研究.%Multistage spouted fluidized flue gas desulfurization (FGD) technique is a new style technique. Experimental and numerical researches about the flow and resistance characteristics of the system were carried out for energy conservation. The results indicate that the performance of the rectifying plates has prominent influence on the system. Using one vertical plate can adjust the flow field effectively. The multistage spouted adopter can lower the height of the tower obviously. The adaptability of the load can reach 40%-100%. In the first stage tower, the gas velocity is about 10 m/s in the center and 6 m/s near the wall. In the upper area of the tower, the peak values of the velocity appeared deflectively. The resistance loss of the new rapid separator is smaller, which takes about 23.7% of the total resistance loss. The resistance loss of inlet is the greatest, which takes about 51%. So it needs further optimization studies for energy conservation.
