团聚液雾化气泡粒径分布特性的可视化研究
Visualization study of reunion liquid atomization bubble size distribution characteristics
摘要
Abstract
Reunion foam is an effective method for removal of fine particulate matter of PM2.5. The particle sizes of the reunion liquid when atomize were studied to choose the suitable bubble size and spray conditions for the aggregation of PM2.5 solution. The foam bubble size and aggregate amount of particulate matter were estimated according to the formulas. By CCD,the finely atomized liquid foam movement from nozzles was recorded. To calculate the atomization bubble size and distribution, MATLAB was used for the image processing. Results showed that the atomized foaming agent could promote the liquid to form bubbles and increase the diameter of the atomized particles. The bubble size of PAM reunion liquid was small,and the atomized particle density was big,the mainly particle size was less than 200μm,while the XTG bubble size was large,and the CMC bubble size was in between. The 0.2% CMC liquid gave the uniform bubble size,and larger number of particles. At a distance of 20cm at the axial spout,the bubble crushing and aggregation were stabilized. When the spout diameter is 0.5mm,the mostly bubble particle sizes are in the range of 100 to 300μm,suitable to the bubble conditions for removal of PM2.5. As the solution temperature increases,the number of atomized bubble particles of 0 to 300μm is increased significantly.关键词
