The key items influent on the characteristics of spraying have been also studied in the dissertation, we can get a good spraying result by adjusting the related parameters efficiently. ( 3 ) the theoretical model of the dynamical parameters such as temperature, moisture, pressure and contour for hot medium and particle inside the drying chamber were obtained by model, utilized the computational fluid dynamics technique to solve the problem between spraying droplets medium by arranging the double grid dispersing structure and rotary outlet structure and the developed structure improved the drying efficiency and product quality
（ 3 ）採用-模型實現了壓力噴霧乾燥塔的溫度場、濕度場、流場的理論建模，利用計算流體力學（ cfd ）技術來解決噴霧乾燥過程中熱介質與霧滴間的傳熱傳質以及動量傳遞和湍流擾動等問題，避免了乾燥過程中的設計不合理狀況；通過增加雙格柵均風裝置和旋轉出風裝置，改善了乾燥塔內的熱質傳遞，提高了乾燥塔的體積蒸發強度。The dehydration time is square of the droplets diameter so the small diameters of the droplets can cut down the drying time then reduce the height of the drying chamber. to the combined spin - flow pressure spray drying, the diameters of droplets are small and the dehydration rate is higher so keeping the qualities of the dried products we can increase the speed of the inlet wind and reduce the temperature of the outlet wind thus can improve the evaporation intensity of the drying chamber and the average energy utilization of the drying equipment
因霧滴的脫水時間與其直徑的平方成正比，減小液滴直徑有利於縮短乾燥脫水時間，可有效降低乾燥塔的高度；由於旋流式組合壓力噴嘴霧化滴徑的減小，脫水速度明顯加快，在不影響乾燥物料性質的前提下，適當提高進風溫度，同時有效地降低排氣溫度，有利於提高幹燥塔的蒸發強度，也有利於提高幹燥設備的平均能源利用率。In this dissertation, the author summed up the muti - technique in fluid dynamics, heat and mass transferring, mechanical designing and computational technique and studied the conventional pressure spray dryers with different air disperse structure and outlet equipment, at last put forward the theme i. e. the study on combined spin - flow pressure spray drying technology, the main contents were as follows : ( 1 ) the combined spin - flow pressure nozzle was designed whose novel structure has no report at present, and the structural designing parameters were obtained through analyzing the physical characteristic of materials and distribution of particles
