倾斜筛板多级逆流结晶器理论及实验研究的中期报告摘要：本研究旨在探究倾斜筛板多级逆流结晶器的理论性能，并分析实验结果验证理论模型的准确性。首先从固液相平衡、溶液流体力学、结晶动力学等方面建立了理论模型，并给出了数值模拟结果。接着进行了多级逆流结晶器实验，得出了生长速率、结晶器收率、晶体颗粒形态等实验数据，并与模型预测的结果进行了对比分析。结果表明，理论模型能够准确预测多级逆流结晶器的性能，并与实验数据吻合较好。关键词：倾斜筛板；多级逆流；结晶器；理论模型；实验研究Abstract:Theaimofthisstudyistoinvestigatethetheoreticalperformanceoftheinclinedscreenplatemulti-stagecounter-currentcrystallizerandanalyzetheexperimentalresultstoverifytheaccuracyofthetheoreticalmodel.Firstly,atheoreticalmodelwasestablishedfromtheaspectsofsolid-liquidphaseequilibrium,solutionfluidmechanics,andcrystallizationkinetics,andnumericalsimulationresultsweregiven.Then,multi-stagecounter-currentcrystallizerexperimentswereconductedtoobtainexperimentaldatasuchasgrowthrate,crystallizeryield,crystalparticlemorphology,andcomparisonanalysiswiththemodelpredictedresults.Theresultsshowedthatthetheoreticalmodelcouldaccuratelypredicttheperformanceofmulti-stagecounter-currentcrystallizerandmatchwellwiththeexperimentaldata.Keywords:inclinedscreenplate;multi-stagecounter-current;crystallizer;theoreticalmodel;experimentalstudy
