负压差移动床立管料斗中散体颗粒流动特征

当散体颗粒在负压差移动床立管下端连接的锥形料斗中流落时，对料斗上方和气室中大无畏动分别加以采集，经过快速建立傅立叶变换处理，得出：在压力和气泡控制区，料斗上方和气室中压力波动特征表现在低频区有较小的波动幅值，而在气拴控制区内，料斗上方和气室中压力波动特征不仅在低频区有较高的幅值，而且两者压力波动信号相位相差π，这些压力波动特征可以用来监测料斗中散体颗粒的流落状态。     

散体颗粒“料泛”特性测量方法

根据散体颗粒的性质，提出新的“料泛”准数关系式Ｓｇ＝ｈ１／ｈｊ．如果Ｓｇ＞１．０，则散体颗粒有“料泛”趋势，并且“料泛”趋势随Ｓｇ值增大而增强，而当Ｓｇ＝１．０时，散体颗粒没有“料泛”趋势．实验结果表明：此实验方法同Ｂｒｕｆ的方法［３］相比，具有操作简单、数据测量方便、所建立的“料泛”准数物理意义明确等特点

内下料式重力混料仓的实验研究

A novel gravity blender with an inner downcomer was experimentally studied in this work. The flow characteristics of solid through the downcomer with branch pipes and the influence of the number of intake openings and their axial position along the downcomer on blending efficiency were investigated. The results of tracer experi-ments show that better blending quality can be obtained if the intake openings along the downcomer are designated according to the equal time interval principle. More intake openings are beneficial for blending efficiency, and the solids flow rate through the branch pipes along the downcomer can be predicted by the Beverloo equation.     

30%TBP-煤油/HNO3体系在折流板脉冲萃取柱中的水力学性能

在Φ100mm折流板脉冲萃取柱中实验考察了30％TBP-煤油1mol/LHNO3体系下的萃取柱操作参数（脉冲振幅、脉冲频率、流速和流比）、结构参数（板间距）对萃取柱水力学性能（液泛通量、液泛存留分数和正常操作时分散相存留分数）的影响。实验研究结果表明：液泛通量随脉冲强度的减小而增大，与流比和板间距无关，研究给出了液泛通量与脉冲强度间的关联式；操作参数和柱结构参数对液泛存留分数的影响均可忽略；正常操作时分散相存留分数与连续相的流速、流比成正比关系，而与脉冲频率无关，并随板间距和脉冲振幅的增大而增加。 

带有文丘里反向流动转向器的紧凑型气动式脉冲射流泵(英文)

A compact pneumatic pulse-jet pump with a Venturi-like reverse flow diverter,which consists of a nozzle and diffuser,is designed for lifting and transporting a hazardous fluid through a narrow mounting hole.The pumping performance for a liquid mixture or a liquid-solid mixture is examined in terms of the effects of liquid viscosity,particle mass concentration,lifting height,and compression pressure.Results reveal that the pumping performance of the compact pneumatic pulse-jet pump is controlled by jet inertia and the flow resistance of the riser tube positioned after the diffuser.The capacity of the compact pneumatic pulse-jet pump increases with compression pressure and decreases with liquid viscosity.However,even for a liquid mixture with a high viscosity of 7.38 mPa·s,a pumping capacity of 170.7 L·h-1 was observed.For a liquid mixture,two dimensionless indices of performance were found to be the ratio of Euler numbers Euout/EuDV and the suction factor q.As the liquid-solid mixture was lifted to elevation of 6.74 m by the compact pump,the particle size distributions of the liquid-solid mixture in the tank and from the riser tube outlet were determined by a particle size analyzer and found to coincide well.
