Background technology
At present in petrochemical industry although large-scale industrial application reactor is mainly fixed bed and fluid bed, but They there is also some shortcomings.Such as, acutely, conversion ratio is low, and catalyst is easily taken out of for fluid bed axial backmixing, product and catalyst It is difficult to separate, and running cost is high.Fixed bed liquid phase diffusional resistance is big, and radial direction heat transfer efficiency is low, is also easy to produce channel, bed pressure drop High.And magnetic stablizing bed research and application cause extensive attention.
Magnetic stablizing bed be fluidization technology and electromagnetic technique perfect adaptation, it be axially, time-independent sky Between formed under uniform magnetic field, the stable bed of only faint motion.Magnetic stablizing bed have fixed bed concurrently and the many of fluid bed is excellent Point.It can be unlikely to cause too high pressure drop as fluid bed using solid small particles, and the effect of externally-applied magnetic field has Control time back-mixing to effect, uniform voidage makes to be less prone to channel inside bed again;The flowable of fine particle makes Solid must be loaded and unloaded very convenient;The solid particle often occurring in fluidized bed process not only can be avoided to run off using magnetic stablizing bed Phenomenon is it is also possible to avoid the hot localised points being likely to occur in fixed bed;Simultaneously magnetic stablizing bed can stablize in wider scope Operation, can improve interphase mass transfer with bubble crushing.Magnetic stablizing bed is a kind of new, creative bed form.
Gas-liquid-solid three-phase magnetic stablizing bed when gas speed relatively low when, starting to be passed through bed during gas during three-phase is magnetic stablizing bed has contraction Phenomenon.When gas speed is relatively low, the solid state shape during three-phase is magnetic stablizing bed and liquid consolidate magnetic stablizing bed similar, bed expansion characteristic and liquid Though magnetic stablizing bed similar, bed is solid magnetic stablizing bed stable not as liquid, and on bed, interface is unintelligible.In bed, gas flowing is divided into Bubble coalescence area and bubble dispersion area, when liquid speed is larger, magnetic field intensity is relatively low, bubble is uniformly dispersed, bubble is little, now bed Operation is in bubble dispersion area;When liquid speed is less, magnetic field intensity is higher, Air Bubble Size differs, disperses uneven, bed center Place's big rate of climb of bubble is fast, and now bed operation is in bubble coalescence area;The operating area favourable to phase reaction is bubble Dispersion area.Minimum fluidisation liquid speed reduces with fast increase of gas, and solid particle drag-out is with gas speed increase and magnetic field intensity reduction Increase.In bed, Average Air Content increases and increases with gas speed and magnetic field intensity.
For gas-liquid-solid three-phase is magnetic stablizing bed, gas-liquid distribution operates particularly significant, so needing gas for bed The perforate of liquid distribution grid designs, to meet requirement of experiment.In addition, former magnetic stablizing bed cold work die device gas is directly used Air compressor is connected to reactor air inlet, leads to admission pressure unadjustable, and has seasonal epidemic pathogens speed unstable, and then has influence on whole The stablizing of individual bed.
