内循环流化床冷渣器内颗粒混合特性试验研究的中期报告摘要：内循环流化床冷渣器是化工行业中常见的一种设备。在实际生产过程中，该设备运行中的颗粒混合情况会影响该设备的操作过程和效果。本实验以内循环流化床冷渣器为对象，研究了内部颗粒的混合特性。分别进行了不同流速、不同流化速度及不同操作时间的试验，测量颗粒的混合度指标和混合时间。实验结果表明：随着流量和流化速度的增加，颗粒的混合时间明显减小，颗粒的混合度提高。随着操作时间的增加，颗粒的混合时间和混合度均呈现出缓慢上升的趋势，并在一定的时间范围内达到平稳状态。关键词：内循环流化床冷渣器；颗粒混合；混合时间；混合度Abstract:Theinternalcirculatingfluidizedbedcoolerisacommonequipmentinthechemicalindustry.Intheactualproductionprocess,theparticlemixingsituationduringtheoperationoftheequipmentwillaffecttheoperationprocessandeffectoftheequipment.Inthisexperiment,themixingcharacteristicsofinternalparticleswerestudiedwiththeinternalcirculatingfluidizedbedcoolerastheobject.Experimentswereconductedatdifferentflowrates,differentfluidizationvelocitiesanddifferentoperatingtimes,andthemixingdegreeindexandmixingtimeofparticlesweremeasured.Theresultsshowedthatastheflowrateandfluidizationvelocityincreased,themixingtimeofparticlesdecreasedsignificantly,andthemixingdegreeofparticlesincreased.Withtheincreaseofoperatingtime,themixingtimeandmixingdegreeofparticlesshowedaslowupwardtrend,andreachedasteadystatewithinacertaintimerange.Keywords:internalcirculatingfluidizedbedcooler;particlemixing;mixingtime;mixingdegree
