摘要：在液体燃料合成浆态搅拌反应器中设置了以金属烧结板为过滤介质的内过滤器,实现固液分离。研究了压降、温度、搅拌转速、固含率、过滤介质孔径及颗粒粒径对过滤速率的影响。实验结果表明:在浆态反应器中进行内过滤可以得到澄清稳定的滤液;随着操作进行,滤饼厚度达到动态平衡,过滤速率最终趋于稳定;过滤速率随着压降、温度、过滤介质孔径、颗粒粒径的增大及搅拌转速、固含率的减小而增大。应用因次分析法建立过滤模型,通过麦夸特算法对实验数据进行最优拟合得到模型的参数值,统计检验以及模型计算值与实验值的比较表明该模型可靠。
The internal filter made of sintered metal plate as filter media was installed to achieve solid-liquid separation in the stirred tank slurry reactor. The influences of pressure drop, temperature, rotational speed, solid content, filter media pore size, and particle diameter on filtration rate were investigated. The results show that clarified and stable filtrate is gained through internal filtration in the slurry reactor, and the cake thickness reaches dynamic balance and the filtration rate tends to stabilize with the operation carrying out. The filtration rate increases with the increase of pressure drop, temperature, filter media pore diameter, particle diameter and the decrease of rotational speed, solid content. The present investigation is useful to practical production. Filtration model is established through dimensional analysis, and values of parameter are gained by using Michael Marquardt algorithm. The statistical test and the comparison between calculated data and experimental data reveal that the model is reliable.
