In a stirred tank chemical reactor the mean age of the reactor contents affects a number of properties of the product, including for example the homogeneity of the product. The mean average age of the reactor contents can be determined by constructing a transparent model of the reactor and filling it with a fluid containing a fluorescent dye and having flow properties comparable to those of the reactor in use. A light is shone on the fluid as it is stirred under reaction conditions and a clear fluid flow into the model. Pictures are taken of the reactor contents and the mean fluid age of the contents of the model are determined relative to the exit age of the contents. This approach can be applied to determine for example which reactor ports to use, what agitator to use, what flow rates to use to improve reactor function.
在搅拌罐
化学反应器中,反应器内容物的平均年龄会影响产品的一系列特性,例如包括产品的均匀性。要确定反应器内装物的平均平均年龄,可以建造一个透明的反应器模型,并在其中注入含有荧光
染料且流动特性与使用中的反应器相当的流体。在反应条件下搅拌流体时,用灯光照射流体,透明的流体流入模型中。拍摄反应器内容物的照片,确定模型内容物的平均流体龄与内容物出口龄的关系。这种方法可用于确定使用哪种反应器端口、使用哪种搅拌器、使用哪种流速来改善反应器功能等。
