【摘要】：基于二流体超音速雾化技术原理,设计了二流体超音速雾化气溶胶制备系统和胶体粒度分布分析系统,应用该系统对雾化胶体粒度分布进行研究,测试了不同压力、不同型号雾化喷嘴在不同位置的雾化粒度参数。试验结果表明:供气压力为0.6MPa,水压力分别为0.6、0.8、1.0、1.2MPa时,沿喷雾轴向距喷头300、500、700 mm处随着轴向距离的增加,雾化粒径先变小后趋于稳定;在同一大气压和水压下,随着喷嘴孔径的变大,流量变大,雾滴平均粒径变小;液体压力为1.2MPa、气压为0.6MPa条件下MAL1130B1喷嘴雾化粒度最佳。
[Abstract]:Based on the principle of two-fluid supersonic atomization technology, a two-fluid supersonic atomization aerosol preparation system and a colloidal particle size distribution analysis system are designed. Atomizing granularity parameters of different types of atomizing nozzles at different locations. The experimental results show that when the gas supply pressure is 0.6 MPA and the water pressure is 0.6 MPA, the atomization particle size decreases first and then stabilizes with the increase of the axial distance from the nozzle to the nozzle 300500700 mm, and at the same atmospheric pressure and water pressure, the nozzle diameter increases with the increase of nozzle diameter. The average particle size of the droplet decreases with the increase of the flow rate, and the optimal atomization size of the MAL1130B1 nozzle is obtained when the pressure is 1.2 MPA and the pressure is 0.6MPa.
