Title: Contrast Experiment of the Spray Characteristics of Four Atomizing Nozzle
Abstract: A series of atomization experiments is done for four commonly used atomizing nozzles in wet flue gas desulfurization.A high speed digital camera is used to take the atomization photos under different hydraulic pressure and the photos are analysised with ImageJ.Then get the spray particle,distribution of the spray particle and the spray angle.The results of the experiments show that the pray particles of four kinds of nozzle become smaller with the increase of the hydraulic pressure.The pray particle of spiral nozzle is smallest and that of fan-shaped nozzle is largest.The spray angles of spiral nozzle,fan-shaped nozzle and hollow cone nozzle are relatively stable with the increase of the hydraulic pressure.And that of Solid cone nozzle becomes larger with the increase of the hydraulic pressure.The spray angles of Spiral nozzle and Fan-shaped nozzle are relatively larger and the spray angle of Hollow cone nozzle is smallest.The spray particles of all the four kinds of nozzle are unevenly distributed under 0.2MPa and are relatively evenly distributed above 0.2MPa.Comprehensively considering the structural characteristics and atomization characteristics,spiral nozzle is more suitable for wet flue gas desulfurization system in thermal power plant.
