Description
Technical field
The application relates to each with chemical industry, Coal Chemical Industry, chemical fertilizer industry and other various chemical equipments of petroleum refining
Kind of large-scale high-grade reactor technology field, such as, gas fluidized bed reactor, carries out the hydrogenation reaction reacted by catalyst
Device or desulfurization reactor etc., particularly relate to a kind of spill airflow-distribution board and reactor thereof.
Background technology
Chemical reactor, include include cylinder, be arranged at cylinder two ends end socket, be arranged at end socket material turnover
Mouthful, the airflow-distribution board that is arranged in cylinder and for supporting the inner supporting structure of airflow-distribution board, or cylinder inner catalyst
Supporting structure, have also includes pressure vessel inside surfacing applied corrosion resistant lining.
Developing towards the direction of scale recently as petrochemical plant, it is increasing that the volume of reactor becomes,
Not only floor space is big, and tall and big device structure brings a series of problem to design, manufacture, transportation, installation, maintenance.
Another kind of problem is that course of reaction logistics capacity is big, gas velocity causes vibration soon and easily, difficult in maintenance.
Additionally, along with social economy's demand to new grades reactor, use traditional reactor can not meet technique need
Ask.New technology is simple, operating condition is gentle, simplifies operation, and therefore, yield is high, and raw material, energy expenditure ratio are low, fluidisation
One of bed reactor then development trend representing state-of-the-art technology, its structure and the technique that it is critical only that inside reactor of technology
Edema caused by disorder of QI fabric swatch.
In fluid bed production technology, gas distribution grid is to ensure that gas-solid fluidized bed have good and stable fluidized state
Important component, directly affect the endocorpuscular flow pattern of fluid bed and fluidization uniformity, be that fluidized bed reactor designs is musted
The critical component that need to consider.Gas distribution grid determines generation frequency and the original state of gas-solid contact, the internals of bubble
Then directly affect whole fluidised form.
In prior art, the gas-solid fluidized bed distribution grid of inside reactor is circle flat structure, circular platform type distribution grid
With structures such as funnelform turbinations, more or less also exist that anti-deposit is indifferent, stability is the highest, easily by active substance
The defects such as blocking, there is also the problems such as original distributing plate structure function adaptability after reactor shell structure large-scale.
Wherein the instability problem of fluidizing gas bed can be divided into the two big classes such as primary unstability and secondary unstability.
Distribution grid is that the flat structure of circle is deposited subject matter both ways and is: one is that production capacity is restricted, be same
Design two kinds of through holes on block flat board, the air-flow under flat board through through hole toward while stablizing upstream, allow washer
Granule product is through through hole swimmingly toward dirty, and along with the lifting of production capacity, the two passes of raising and lowering can occur blocking at random；
Two is that the lateral forces relatively housing of circle flat board is poor, is easily deformed, and structure and air-flow deviate original design.But plate distribution
Plate is due to its simple in construction, easily manufactured, and is widely used.But this structure has one in fluid-bed granulation
Fixed defect, on the basis of analyzing plate distribution grid deficiency, circular platform type distribution grid and funnel conical structure are changed
Enter.The outlet that product particle collects from funnel central bottom is sent, and process gas then passes through the air-flow of circumferentially opening on distribution grid
Hole is flowed out.
Distribution grid is that funnelform turbination structure exists three aspect subject matters:
One is the three-dimensional non-equilibrium of process gas fluid bed, and process gas forms spiralling air-flow in distribution grid funnel, rotation
Stream causes circumference fluidised form and axial fluidised form the most unbalanced in ascending motion because of energy dissipation so that material from top to down exists
Reaction progressively generates granule, the peritropous shell wall of granule stream thick under the centrifugal action of eddy flow, easily causes radial flow
State is unbalanced.Second, it is the stream pressure regulation and control difficulty at distribution grid upper shed, this is due to funnelform turbination structure
Distribution grid space below is gradually expanded during rising, and the process gas below distribution grid is in the process risen
In, make the process gas total amount below distribution grid gradually decrease because part flows out from radial opening, thus air pressure substantially reduces.
3rd, it is that distribution grid funnel gos deep into being formed in low head overlapping nested relationship, the process gas come in from end socket limits because of space
Bottom strong erosion funnel, cause the strong variations of air flow press molding and the vibration of funnel, connection loosing that vibrating fatigue causes or
Cracking produces again the process gas runner that some are additional, upsets original design of Fluidized bed, enters structure and technique vicious cycle.This
Outward, distribution grid originally there is also some other problemses being not easy to mounting and adjusting.
Analyze the reason of the problems referred to above, be distributing plate structure design mainly to highlight infundibulate for collecting product particle
Function, and despised its impact on air-flow, have ignored the effect of process from the visual angle emphasizing result.Analysis is had to refer to
Going out, two dimensional fluidized bed is owing to being affected by wall effect, and its fluidal texture and three-dimensional fluidized bed exist bigger difference, and gas eddy is only
Can develop at two-dimensional space, in bed, be easier to that the flat gas eddy of large scale occurs.Therefore, in two-dimensional bed, easily form joint gush etc. no
Stabilization fluid situation, and the overall circulation of similar three-dimensional bed can not be formed.Also point out after having comprehensive study analysis, strengthen distribution
The gas speed of plate central area is crucial.
In addition to distributing plate structure, the pore on distribution grid is also the key affecting fluidized bed state.In each uneven cloth hole
In fluid bed, the gas eddy produced in big hole separation arrangement air distribution plate fluid bed is relatively small and dispersibility preferable, gas phase velocity
Vector distribution is relatively decentralized homogeneous, and fluid effect is best.
Therefore, for the problems referred to above defect, a kind of airflow-distribution board of research and development, it is possible to make process gas in barrel type reactor
Equiblibrium mass distribution flows up, and makes the grain products of generation be collected by distribution grid simultaneously and discharges from bottom, moreover it is possible to opposing logistics capacity
Greatly, gas velocity is fast and the vibrating fatigue that causes, will meet pressure drop stability and the good anti-deposit distribution grid of fluidization quality, application
In petrochemical industry reactor, steady production and economic benefit had important engineering significance.
