摘　　要：阐述烟气粉尘脱硫治理和喷射系统的结构。计算治理塔内液膜的层流底层和湍流层的速度、液膜的总流量及雾化旋动流体的附加流量。分析了治理塔内旋动气———固微粒流的分离性能 ,通过实验求得塔内旋流的准自由涡区的速度分布 ,计算分离的最小粒子直径。文中研究脱硫剂的动态喷雾与烟气含硫化合物的化学反应过程 ,讨论影响脱硫除尘治理效果的主要因素和喷射器的作用。最后介绍在工业炉窑烟气脱硫 (SO2 或硫化物 )The structures of system for separating sulfur from flue gas and dust and jet system are described The velocities of turbulent flow and laminar flow inside the tower,the total flow of liquid membrane,and the additional flow of rotation spraying fluid are calculated The separating characteristic of notation ari_solid is analyzed on the tower The velocity distribution in quasi_free vortex area is obtained from experiment The minimum separated particle diameter is computed The chemical reactions of flue gas contained sulfide with the dynamic spraying separating sulfur agent are studied The main factors related to the effect of separating sulfur and dust and function of air ejector are discussed At last,the applications of separating sulfur in industry stove and collecting dust in environmental engineering are introduced
