作者简介

  Mooson Kwauk graduated from University of Shanghai in1 943 and researched in fluidization under the late ProfessorRichard Wilhelm at Princeton University from 1 945 to1947.He has continued working in this field both in theUnited States and in China,and iS now Professor andDirector Emeritus of the Institute of Process Engineering ofthe Chinese Academy of Sciences,to which he was electedMember in 1980.In 1989 he received an InternationalFluidization Award of Achievement at the Sixth International Fluidization Conference held in Banff,Canada.The author postulates an idealized system of completehomogeneity that can be used in the analysis of many engineering problems,e.g.,·generalized fluidization with both solids and fluid in flow·fluidized leaching and washing·solids mixing and segregation·operation of conical fluidized bedsThese problems arise in hydraulic classification according to particle size anddensity,sedimentation and classification,continuous ion exchange or adsorption,watertreatment,fluid-bed e...

内容简介

When fluidization was first employed industrially,e.g., in the Winkler gasifier, we had only the bubblingfluidized bed as shown in the middle diagram of thefigure, in which gas bypasses as bubbles, thus leadingto poor solid-gas contact and incurring large pressuredrop. What is ideal is the high dispersion of solidsshown asthe background of the book jacket. Short ofsuch an ideal state, we may resort to suppressing bubblesby the use of shallow fluidized bed as shown on thelefthand side diagram achieved through reducing thesolid content of the fluidized bed. or the fast fluidizedbed with continuous recycfing of solids to the bottomof the bed, as shown on the righthand side diagram. Allthese diagrams of fluidization were generated throughcomputer modeling by Professor Wei Ge, and fromhosts of these diagrams, four were selected by Xue Bai,Jianxing Lu and Ying Ren to portray the principal thesisof this book.
