摘　　要：热浸镀锌时,锌浴上方烟尘的控制和后处理是热浸镀锌领域的研究热点,目前尚未找到更有效的控制措施。针对侧吸式烟尘收集装置从设计上进行了改进,并运用FLUENT软件对15°、30°和45°吹风口结构烟尘收集的流场进行了数值模拟与分析。结果表明,射入气流角度对烟尘收集效果影响明显,其中30°入射角,烟尘收集最为理想;15°入射角时,吹风口的帽檐影响工件取出,不能有效地阻挡锌液飞入;45°入射角时,入射气流形成的气幕过窄,从而不能有效地阻挡控制烟尘气体的流向。研究结果对热浸镀锌池上方烟尘收集装置的进一步设计及优化提供了理论依据。It is the hot topic that smoke-control and post-processing in the hot-dip galvanizing, however, there is still no effective measure to control it. This paper aimed at the lateral suction style to modify the dust collection device from the beginning of design, and then numerically simulated and analyzed the airflow field of the dust collection device of three blow- back mouth structure about 15°,30° and 45° by FLUENT. The results showed that the angle of incident airflow has significant influence on efficiency in the dust collection. As the angle of incident airflow is 30°, smoke dust collection become efficiency On the contrary, the brim affect the workpiece to remove and do not effectively stop zinc flying into when 15°,and the incident of the air curtain has ineffectiveness on blocking the dust when 45°. The results also provided theory basis to the design and optimization of smoke collection devices above the pool of galvanizing.
