Description

A kind of adsorbing separation inner member and application thereof

Technical field

The present invention relates to a kind of adsorbing separation inner member and application thereof.More particularly, relate to a kind of in the container containing multiple solids bed, collect the fluid that upstream particulated bed flows down, the fluid of collection is fully mixed with the fluid introduced from the external world, and mixed fluid well-distributing is assigned to adsorbing separation inner member in device downstream particulated bed; And use this application of adsorbing separation inner member in adsorbing separation.

Background technology

In petrochemical industry, the process that the fluid carried out in containing the container of solids contacts with solids is widely used in during such as adsorbing separation, catalytic reaction etc. operate.Wherein adsorbing separation is isolation technics conventional in petrochemical industry, and the purification of the mixture close for structure, boiling-point difference is very little has extraordinary effect.Equipment for adsorbing separation has fixed bed, moving bed and simulation moving-bed, wherein the simulation moving-bed capital equipment being current adsorbing separation and adopting.In simulation moving-bed, Stationary liquid adsorbent can be envisioned for is against moving in material moving direction, certain in the middle part of mask work district of mixed material to be separated is a bit inputted continuously, the ratio of the flow velocity of selected both direction flowing, feed liquid is just divided into two parts of reverse flow from porch, take feed entrance as reference point, adsorbent seems to have adsorbed product and moves up, and is therefore called " simulation moving-bed ".Position more than feed points is higher, and product purity is higher, and byproduct is in the opposite direction enrichment.Simulation moving-bed production capacity and separative efficiency higher than fixed adsorption bed, can avoid again that moving bed adsorption weares and teares, channel between fragment or dust occluding device or pipeline and solid particle seam.

When fluid flows through simulation moving-bed, this separation of fixed bed containing solids bed or consersion unit, need to arrange one or more fluid distribution apparatus at device interior, the solid ion in equipment is divided into two or more solids bed.On the solids bed that fluid distribution apparatus is arranged on topmost and between two solids beds, fluid flowing by the cross section in this equipment can be made evenly, thus improve the efficiency of operation.Such as, fluid distribution apparatus is set and can reduces the channel even eliminated in solids bed, short circuit and flow dead, thus reduce the change of the temperature difference and fluid concentrations.

CN102451647A discloses a kind of fluid collection, mixing, distribution apparatus, and the major axes orientation along container generally includes from top to bottom with lower component: upper surface support component, fluid collection parts, fluid rectification part, lower surface fluid distrbution parts.Fluid collection parts are positioned at below upper surface support component, and each parts are arranged successively with rational interval.The fluid rectification part of this equipment uniqueness make to be obtained by the fluid of equipment evenly flowing, can mix more fully and the interference of less flow fluctuation.This equipment has multiple outer shape in addition, can adapt to the use needs of the container of various scale and installation requirement.

CN201592090U discloses a kind of liquid collection mixed allocation device.The feature of this equipment is that inside arranges some maze members for strengthening fluid mixing.

CN101056684A discloses a kind of for the blender-distributor-collector device between the solids bed in fluid-solid contacting container.This equipment comprises the top bed for keeping solids, and allows that fluid flows through the coboundary of described blender-distributor-collector device downwards; To be positioned under coboundary and fluid distributor isolated with this coboundary; Between the two above-mentioned and and both fluid deflector plates of separating respectively; Run through at least one passage of deflecting plates; Also comprise the flow controller being selected from perforated plate, silk screen, grid, porosu solid, cellular object and combination thereof; The perforated area of the large fluid distributor thereon of the perforated area on the flow controller of wherein said foot.This equipment optionally can also comprise a blending bin be connected with pipeline, the introducing of external fluid or extract fluid from container out and all undertaken by this blending bin.This equipment has good distribution effects to the fluid in container, but fluid flow path is in a device longer, there is obvious flow dead, and local can produce high-speed jet, increases fluid by pressure drop during equipment.And when the operation of the importing or extraction of carrying out fluid switches, must rinse pipeline.

CN1316917A discloses a kind of fluid and distributes and gathering system, and this equipment comprises for mixing, distributing or extract some distribution plates of fluid and some laths out.This system has two chambers, and its function class is similar to previously mentioned blending bin, and one of them chamber carries out the introducing of external fluid, and another chamber carries out the extraction of container inner fluid.In operation, when the operation of the importing or extraction of carrying out fluid switches, need not rinse pipeline.This equipment can provide reasonable fluid distribution effects, but internal structure is complicated, increases fluid by pressure drop during equipment.And the increase of chamber quantity causes the increase of number of tubes, reduce the effective volume in container.This equipment contour structures is more single, is suitable for larger container, for less container, installs this equipment more difficult.

In sum, the fluid distribution apparatus used at present also exists following problem to be needed to improve:

(1) fluid flow path is in a device longer, easily forms flow dead;

(2) fluid is in device memory in larger concentration gradient, and fluid chemical field is insufficient;

(3) pressure drop when internal structure causes fluid to flow through equipment is larger.

Therefore, need to overcome the problems referred to above, provide a kind of and improve fluid flow uniformity, fluid is fully mixed, reduce the adsorbing separation inner member of pressure drop when fluid flows through equipment.

Summary of the invention
