Through the special studies on impacts to atomizing and humidifying effect from such factors as the firing pin type, centrifugal structure, higher spraying pressure, less aperture, initial water temperature and original state of the air, some conclusions are obtained, such as : the centrifugal nozzle with firing pin type, high pressure and little aperture has bigger air eddy and atomizing angle. the spaying liquid has high velocity. the droplet is small, and the heat and mass transfer velocity is high
通過對撞針型結構、離心式結構、較高的噴水壓力、較小的噴嘴孔徑、噴水初溫及待加濕空氣初狀態對霧化加濕效果的作用原理的重點分析,得到:撞針型高壓小孔徑離心式噴嘴具有較大的空氣渦與霧化角,噴出的液體流速高、液滴小、水與空氣傳熱傳質速率高,撞針型結構提高了霧化加濕效率,高壓小孔徑的特點為霧化加濕提供了較大的能量,而噴水初溫的升高會減小水的粘性力和表面張力,從而優化加濕效果。Experimental constants include : ambient temperature 291k ~ 301k, rh 15 % ~ 21. 2 %, wind velocity 3. 2m / s at the nozzle position and horizontal to the spray fan, others are same as the fore experiment. the tendency of the two experiments results is consistent with the tendency from simulation. that indicate the improved shield spray is better than the original shield spray in reducing spray drift, and also more better than conventional spray without shield
風洞試驗參數:噴霧藥液為含1 bsf的水溶液,風速1 . 4m s ,風向垂直於噴霧扇面,溫度281k 288k ,相對濕度rh9 20 ;室內試驗參數:噴霧藥液為含2 bsf的水溶液,噴頭處風速為3 . 2m s ,風向平行於噴霧扇面,溫度291k 301k ,相對濕度rh15 21 . 2 ;分別在噴頭下風向噴幅外的空中和地面布點收集飄失和飄移沉積的霧滴量,作為評價減少霧滴飄失效果的指標:試驗結果表明:改進后的罩蓋噴霧減少霧滴飄失的效果好於雙圓弧未開口罩蓋噴霧,常規無罩蓋噴霧的霧滴飄失量大於開口罩蓋噴霧。
