超音波を用いてアルコール水溶液を霧化し,霧化液滴径分布と溶質の濃縮特性について検討した.また,濃縮機構をモデル化し,濃縮特性に及ぼす液滴径分布の影響について検討した.装置には透明塩化ビニル樹脂製の円筒(内径100mm)を用いた.底面中央に超音波振動子(周波数2.4MHz)を設置した.霧化液滴を同伴させるためにガス(空気)を流した.ガスの入口および出口の高さを150および400mmとし,塔断面積基準のガス空塔速度を変化させた.試料にはメタノール,エタノール,プロパノール水溶液を用いた.印加電力を18W,溶液温度を10℃とした.超音波照射後の溶液の体積および濃度を測定し,物質収支より同伴液中の溶質濃度,溶液平均濃度および同伴液流量を算出した.また,液滴径分布を光散乱法(日機装(株)SPR7340)により測定した.霧化液滴径分布は正規分布となり,そのメディアン径および標準偏差を超音波周波数および液物性を用いて表せた.ガス空塔速度が高いほど,同伴液流量は高くなり,同伴液中の溶質濃度は低くなった.これは,ガス空塔速度が低くなるにつれて,濃度が低い大きな液滴が装置外へ同伴されなくなるためと考えられた.同一の溶液濃度については,同伴液中の溶質濃度はメタノール,エタノール,プロパノール水溶液の順に高くなった.気化の影響を無視し,液滴表面は溶質に取り囲まれており,表面溶質量は液滴径に依存しないというモデルから表面溶質量が計算され,その結果,液滴表面における溶質の厚さはアルコールの種類に依存しなかった.また,同伴液中アルコール濃度および同伴液流量は,霧化液滴径分布と表面溶質量から推算された.

The ultrasonic wave is used to modify the aqueous solution, and the droplet diameter distribution of the chemical solution is characterized by its properties. The mechanical properties and the droplet diameter distribution are affected by the temperature, temperature and temperature. The device transparently modifies the grease tube (inner diameter 100mm) and uses it. The bottom center is equipped with ultrasonic vibrator (wavenumber 2.4MHz) setting device. Turn the droplets into the droplets, the companions, the droplets, the droplets. The entrance, exit, height, height Make sure that the solution is used in an aqueous solution. The Inca power is 18W and the solution temperature is 10 ℃. After ultrasonic irradiation, the body temperature of the solution was measured, the solubility in the peer solution, the average temperature of the solution and the flow rate of the companion solution were calculated. The diameter distribution of liquid droplets is measured by the method of light scattering (SPR7340). Chemical liquid droplet diameter distribution, regular distribution, standard deviation, ultrasonic cycle number, liquid physical properties and physical properties. The speed of the empty tower is high, the flow rate of the companion liquid is high, and the solubility of the concomitant liquid is low. The speed of the empty tower is low, and the speed of the empty tower is low. In the same solution, the solubility of the solution is different from that of the concomitant liquid. The surface of the droplet is free of attention, the surface of the droplet is clear, and the size of the droplet is dependent on the size of the droplet. The calculation of the amount of solubility on the surface of the droplet is based on the results of the calculation of the amount of solubility on the surface of the droplet. In the concomitant liquid, the temperature of the companion liquid, the flow rate of the companion liquid, the droplet diameter distribution of the chemical solution, the surface solubility of the solution, and the calculation of the amount of solubility on the surface.
