摘　　要：工业尾气中含有二氧化硫和大量的粉尘颗粒物,采用喷射吸收旋风分离器处理烟气,吸收二氧化硫的同时进行粉尘脱除。通过研究压降、脱硫效率和除尘效率的变化规律,得到最优工艺参数的实际工况条件。结果表明:压降随进气速度和吸收液喷射速度的增加而增加;在吸收液喷射速度为2.8m^(3)/h,进气速度分别为60、45m^(3)/h时,脱硫效率、除尘效率达到最大。SO2 and amounts of dust particles can be found in industrial tail gas and generally employing jet absorption cyclone to remove them was implemented,including investigation of changes in pressure drop,desulfurization efficiency and separation efficiency so as to obtain actual working conditions of the cyclone separator which boasting of optimal technological parameters.Results showed that,the pressure drop increases with the increase of both air-intake speed and absorption liquid’s jet velocity;when the absorption liquid’s injection velocity stays at 2.8m^(3)/h and the air intake speed at 60m^(3)/h and 45m^(3)/h respectively,both desulphurization and dust collection efficiency can reach the maximum value.
