摘要
为了提高喷雾降尘效率,并在工程应用中优选适宜的喷嘴,针对喷雾粒径影响因素进行了分析研究。通过开展实验室模拟试验,得到喷雾场喷雾粒径分布曲线,揭示了不同孔径喷嘴随喷雾压力的变化规律,并对不同类型喷嘴的性能试验结果进行了适用性归类分析,得出了喷雾粒径随距喷口距离、喷嘴孔径的减小而减小,随喷雾压力增加而减小的变化规律,总结了不同作业工序采用喷雾降尘技术时喷嘴选型的依据。模拟生产实际,分析了横向风流对喷雾粒径的影响,为喷雾降尘技术在现场应用提供了参考依据。
In order to improve the efficiency of spray dust reduction and optimize the nozzles in engineering applications,the factors affecting the spray particle size were analyzed and studied.The laboratory test carried out formed the particle size distribution curve of nozzle fogging,revealed the variation law of different aperture nozzles with pressure,and classified the applicability of the performance test results of different type nozzles.The analysis shows that the spray particle size decreases with the distance from the nozzle and narrowing nozzle diameter,and decreases with higher spray pressure.The basis of nozzle selection for different methods of spray dust reduction was summarized.The actual production was simulated and the impact of lateral wind flow on the spray particle size was analyzed,which provided a reference for the field application of spray dust reduction technology.
