Description
Technical field
The present invention relates to a kind of annular spouted bed that disposes hoop multi-port air distribution mechanism, is a kind of high efficient gas-solid contact reactor, belongs to technical fields such as dry materials, living beings gasification, Activated Carbon Production, coal gasification coproduction and coal-fired flue gas desulfurization.
Background technology
Spouted bed technique is an important branch of fluidization technology, and it comes across the initial stage fifties the earliest.Spouted bed technique is mainly used in the cereal drying, granulation, grain coating etc.In addition, spouted bed is also being played the part of important role in technologies such as low-quality coal combustion and gasification, the burning of low heat value industrial waste and gas by partial oxidation of natural hydrogen manufacturing.
Traditional spouted bed structure mainly is made up of spouted gas inlet nozzle, bottom back taper and cylinder body three parts.Fluid (normally gas) is injected vertically upward via an aperture (nozzle or orifice plate) that is positioned at taper bottom centre place, form one with rate of flow of fluid increase and upwardly extending gradually fluerics.When fluid ejection rate is enough high, this fluerics will penetrate bed and produce one pass the dilute phase gas-solid flow bolt (inlet zone) that the bed center moves upward rapidly in particle layers.When these are carried secretly by fluid jet and the particle that moves upward at a high speed passes when rising to a certain height that exceeds bed face around the particle layers (annular space district) that slowly moves down around it; because the attenuating suddenly of fluid velocity, particle can form the fountain district because of gravity falls back to surface, annular space district as fountain.The particle of these fallings slowly is moved downward to the bed bottom along the annular space district, infiltrates again then that inlet zone is carried secretly up again and the interior circulation that forms the as regular as clockwork of particle.This flow phenomenon with dilute phase inlet zone, close phase annular space district, fountain district three district's fluidal textures is exactly spouted phenomenon.
Structure the having a significant impact of spouted bed to spouted phenomenon.For example, when inlet nozzle diameter and spouted column body diameter ratio just the spouted of particle can not occur during greater than a certain critical value, this moment, bed can directly change the aggregative fluidization state into by fixed bed along with the increase of flow velocity.
Traditional fluid bed is prone to layering in operating process and joint gushes, and the heat and mass between convection cell and the particle is unfavorable.Annular space district bottom dead and the reunion of easy bonded particulate in the annular space district then often appear in single spouted bed, influence particle mixing and gas-particle heat transfer and normal operation operation.
For overcoming the influence of spouted bed annulus bottom " dead band ", can feed assist gas in the annulus bottom, make annulus bottom particle layers loose, weaken or eliminate " dead band " basically.If annulus forms the moving bed state, if Here it is the spouted bed of so-called inflation. annulus forms fluidized state, is exactly spouted fluidized bed (fluid injected bed).No matter be spouted bed of inflation or fluid injected bed, its body central authorities all are the jet pipe district, claim the dilute phase delivery area again, are annulus around it, claim concentrated phase area again.The air-supply in the spouted district of the air-supply of annulus and center need could realize good working order in certain ratio range.
The spouted bed of existing many shower nozzles is in spouted bed bottom a plurality of parallel incident nozzles to be set, must distinguish control separately by the flow of each inlet nozzle, and adopt the conical section be interconnected, an easy so interior uneven air that causes, the dead band takes place in local area easily when little air quantity especially.The air quantity of a plurality of ajutages is difficult to control respectively, and practical operation is difficulty very.

Spouted fluidized principle of the present invention is:
Pressurization gas enters air distribution mechanism by the voltage stabilizing air compartment and sprays into annular space, and air distribution mechanism is made of a plurality of nozzles and V-type diversion chamber, material at annular space by spouted fluidized.When material containing amount in the annular spouted bed seldom the time, particle is substantially by the spouted V-type diversion chamber of dishing out, and does the motion of hoop cycle of oscillation in bed.With the further increase of material containing amount in the bed, vibration descends highly to some extent, reaches after certain material containing amount, begins to pile up at the spouted granule materials in air nozzle place and fills.Further increase material containing amount in the bed, the particle material stock of each air nozzle and air-supply become even gradually, the spouted fluidized phenomenon of subregion appears in particle in annular spouted bed, along height of bed direction, be divided into three visibly different spouted fluidized zones: move and the flow region of spouted stirring based on particles filled in (1) V-type diversion chamber; (2) the close mutually spouted fluidized district on V-type diversion chamber top; (3) the particle dilute phase entrainment zone of upper space.
V-type diversion chamber at nearly air nozzle place, air-supply promotes particle spouted stirring or ejection V-type diversion chamber in V-type diversion chamber.In V-type diversion chamber, particle is circulation up and down and the mixing that dominant shape becomes material to fill mobile with spouted stirring substantially; Because the sedimentation of particle is pressed close in the certain thickness scope of oblique deflector wall, particle moves with mobile form, and adjacent V-type diversion chamber is also carrying out the quick exchange of material by oblique deflector on hoop thereby cause.
The close phase of particle motor area on V-type diversion chamber top, because the continuous rising of air cavity, this part stratum granulosum is mainly based on spouted fluidized form, the particle of close phase laminar surface has sprayed fluctuation in certain altitude.Along with increasing of material containing amount, the height of emulsion zone constantly increases, and the spouted fluidized motion of particle is more violent.With the increase of bed endoparticle material containing amount, particle emulsion zone height constantly increases.Under identical particle material containing amount and spouted air quantity, spouted bed height reduces with the increase of particle diameter.
