目前在选择离心沉降分离状态的参数时,往往要利用被分禽悬浮液和乳浊液的分散相粒度分布的数据,但在大多数情况下往分离设备中输送分散系时,由于分散相粒子的破碎和凝聚,分散相颗粒分布的分离性能往往是随颗粒尺寸变化的。此外,在生产条件下也不可能随时确定被分离系的粒度组成;因此,很少有关于对进入离心机转鼓工作区的多相系的分散相的颗粒随尺寸分布的函数的情报,这就使分离状态参数的选择工作相当地复杂。沉降式离心机分离状态的基本特征之一是生产能力Q,对已知颗粒尺寸的系统,可按下式确定~[1]:
At present, when choosing the parameters of centrifugal sedimentation, it is often necessary to make use of the data of the dispersed phase size distribution of the divided poultry suspension and emulsion. However, in most cases, when the dispersion is transported to the separation equipment, the dispersed phase particles Of the broken and condensed, dispersed phase particle distribution of the separation performance often varies with the particle size. In addition, it is not possible at any time to determine the particle size composition of the segregated system under the conditions of production; therefore, there is little information on the particle size distribution as a function of the size distribution of the heterogeneous dispersed phase entering the centrifuge drum working zone The selection of the separation state parameters is quite complicated. One of the basic features of a decanter centrifuge is the production capacity Q, for a system of known particle sizes, which can be determined as follows [1]:
