【摘要】:基于二流體超音速霧化技術原理,設計了二流體超音速霧化氣溶膠制備系統(tǒng)和膠體粒度分布分析系統(tǒng),應用該系統(tǒng)對霧化膠體粒度分布進行研究,測試了不同壓力、不同型號霧化噴嘴在不同位置的霧化粒度參數(shù)。試驗結果表明:供氣壓力為0.6MPa,水壓力分別為0.6、0.8、1.0、1.2MPa時,沿噴霧軸向距噴頭300、500、700 mm處隨著軸向距離的增加,霧化粒徑先變小后趨于穩(wěn)定;在同一大氣壓和水壓下,隨著噴嘴孔徑的變大,流量變大,霧滴平均粒徑變小;液體壓力為1.2MPa、氣壓為0.6MPa條件下MAL1130B1噴嘴霧化粒度最佳。
[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.
