A new type of three-phase fluidized bed has been developed by use of a magnetic distributor plate (MDP).The bubble-supported solids operation characteristics of fluidization with the liquid velocity below the minimum fluidization velocity was investigated.The characteristics of bubbles,the distribu- tion of local holdups and liquid mixing in the MDP three-phase fluidized bed with magnetic alginate beads as the solid phase were measured by the conductive probe and the optical fiber probe.Because the distribution of magnetic field is not even,the three fluidized regions,magnetic aggregative state, chain fluidization and particulate fluidization,were investigated in the bed.The radial distribution of local holdups conform with the parabolical curve.The distribution of local gas holdups was well de- scribed by the formula. ε_(9)=(1.878-0.00368H)ε_(9)(1-Φ-)~2 Under the condition of lower gas and liquid velocity,the liquid mixing was well described by the relationship of the mixing coefficient and the modified mixing model. F(t)=1-exp,[(-t/(t(0.2852+0.0000419H~(?))Q_9~(?)] It was found that the magnetic field made particles penetrating into the bubbles and break them, and both bubble diameter and bubble velocity decreased with increase of magnetic strength.The rela- tionships of the probability of small bubbles(<2mm)and lower velocity bubbles were obtained based on the experimental results.

Intermediate state fluidization is represented by a fuzzy set. One parameter, heterogeneity, deduced from statistical characteristics of fluidization voidage spectrum and εmf,is defined as the membership function of the fuzzy set. Interpretation by fuzzy sets of gas- solid and liquid -solid fluidization experiments under various pressures,fluid viscosities and particle properties, illustrates that the configuration of two - phase structure in fluidized bed varies with operating parameters as well...

Intermediate state fluidization is represented by a fuzzy set. One parameter, heterogeneity, deduced from statistical characteristics of fluidization voidage spectrum and εmf,is defined as the membership function of the fuzzy set. Interpretation by fuzzy sets of gas- solid and liquid -solid fluidization experiments under various pressures,fluid viscosities and particle properties, illustrates that the configuration of two - phase structure in fluidized bed varies with operating parameters as well as material properties. By means of fuzzy sets,the heterogeneity,or the grade of aggregative,of a certain fluidization state can be referred to as a specific number ranging from 0 to 1.

用模糊集合描述流化床的状态,从流化床空隙率脉动谱归纳出其不均匀度作为模糊集合的隶属函数.流化床在任何状态下的不均匀度或聚式化度都可用0~l之间的1个数值表示.对液固流态化和气固流态化实验进行观测和描述说明,模糊数学方法能够反映流化床两相结构的存在、漂移和转化,也能体现密度、粘度、粒度和表面性质的因素对流态化状态的影响.
