The effect of empty tower used in wet-process phosphoric acid production is better by comparison with filled tower. 通过空塔与填料塔在湿法磷酸过程中的应用情况对比,说明空塔用于湿法磷酸生产运行效果良好。
Reason of filled of tower that absorb the remnant air and Its Preventions 尾气吸收塔满塔原因及预防措施
The applications and developments of CFD in chemical engineering field which included filled tower, cyclone separator, biochemical reactor, exsiccator, fluidized bed, heat exchanger are reviewed. 本文主要综述了CFD技术在化工领域内的填料塔、旋流分离器、生化反应器、干燥器、流化床、换热器方面的应用。
Under the conditions of 1 ∶ 10 of phase volume ratio, about 60 ℃ of temperature and pH6~ 8 in a filled tower, the recovery rate of anthraquinone compounds is over 98%. 用填料塔在相比(体积比)1∶10、温度60℃左右、pH6~8条件下,回收率达98%以上。
In recent years, concrete filled steel tube has been applied to the construction of cable tower. Combining with the advantages of steel tower and concrete tower, steel tube concrete tower section is less than reinforced concrete tower. 近几年,钢管混凝土也应用到了斜拉桥索塔的工程中,结合了钢塔与混凝土塔的优点,钢管混凝土塔截面小于钢筋混凝土塔。
