摘　　要：为研究脱硫塔内的气液分布情况对脱硫效率的影响,选用FLUENT作为计算工具,以烧结烟气氨法脱硫塔作为研究对象,对塔内气相湍流采用Euler方法描述,对喷淋液滴采用Lagrange颗粒轨道模型描述,研究烟气入口倾角和入口距离浆液池液面高度对脱硫塔内气液两相流场分布的影响,并对脱硫塔的关键参数取值给出建议.To study the effect of gas-liquid distribution in desulfurization tower on the desulfurization efficiency, FLUENT is chosen as the calculation tool and a desulfurization tower of sintering flue gas ammonia process is taken as the research object. The Euler method is used to describe the gas-phase turbulence, and the Lagrange particle trajectory model is used to describe the Spray droplets. The effect of gas inlet angle and height from inlet to liquid surface of slurry pool on the gas-liquid two-phase flow in desulfurization tower is analyzed, and the Values of key parameters of desulfurization tower are suggested.
