摘要:: 本文旨在开发一种新型磷酸反应器──具有类似太极图曲线形隔板的单槽双区四桨反应器（ＲＴＣＢ反应器）。首先以自来水和磷石膏为搅拌介质进行冷模实验，冷模实验结果表明，ＲＴＣＢ反应器具有功耗低、悬浮、混合效果好、停留时间分布合理等优点。然后，采用同样的二水物流程工艺条件，选取道尔槽作参照物进行热模实验，热模实验结果表明，相同条件下与道尔槽相比，ＲＴＣＢ槽具有省功、磷石膏结晶环境优越、磷石膏洗涤率稍高等优点，但磷矿萃取率稍低，可望用于湿法磷酸的工业化生产。本文的研究工作将为该反应器的进一步开发应用提供依据。

Abstract:: This article aims to develop a new type of phosphate reactor -a single groove and double -zone four paddle reactor (RTCB reactor) with a curve similar to the Taiji graphic curve. First, use tap water and phosphide to perform cold mold experiments for the mixing medium. The results of the cold mold experiment show that the RTCB reactor has the advantages of low power consumption, suspension, good mixed effects, and reasonable residence time distribution. Then, the same two -water process process conditions were adopted, and the Douer trough was used for reference to perform the heat model experiments. The results of the heat model showed that compared with the Douer groove, the RTCB groove has the advantages of saving power, superior phosphide crystalline environment, and slightly high phosphide washing rate. The research work in this article will provide a basis for the further development and application of the reactor.
