Description
Technical field
The present invention relates to a kind of material-flow mixing and dispersing device, be applicable to that fluid is when the small bore basin enters the basin, heavy in section, impulse force is subdued in enforcement, fluid disperses and gas-liquid mixed, more particularly, relate to that the gas-liquid mixed logistics mixes the gas-liquid mixed logistics and evenly be dispersed to the equipment in whole reactor cross section in a kind of fixed bed hydrogenation reactor when entering reactor.
Background technology
In the PETROLEUM PROCESSING field, extensive use fixed bed drip-flow reactor in the hydrofinishing of fraction oil, paraffin, lubricating oil, the hydrocracking of wax oil and the most residual hydrocracking technology.In the fixed bed drip-flow reactor, the gas-liquid mixed logistics and the flow direction are reacted by beds down.Can the hydrogenation reactor inner catalyst play one's part to the full, whether product quality can reach high-quality, depends on the logistics distribution effect of reactor bed porch to a great extent.Gas-liquid mixture is by pipeline and when flowing to into the hydrogenation reactor top, and the area of section sudden enlargement that fluid is flowed through is more than 80 times, rate of flow of fluid height, easily bias current, and there is bigger thermograde in gas-liquid two-phase simultaneously.If fluid directly is sprayed onto on the distribution plate of top, can produce strong wallop, influence the logistics distribution effect of top distribution plate, and then have influence on the logistics distribution effect and the catalyst utilization of top distribution plate below beds, shorten the service life of catalyst, force reactor to be stopped work too early.Therefore, evenly spread to the entire top distribution plate as far as possible to the impact of top distribution plate and with fluid, make gas-liquid two-phase produce premixed simultaneously, generally the logistics diffuser is set at the reactor inlet place to eliminate thermograde for slowing down the reactor inlet high-velocity stream.The hydrogenation device for treatment amount constantly increases in recent years, and the scale of hydrogenation reactor is tending towards maximizing, and therefore the performance and the design thereof of logistics diffuser is had higher requirement.
The mentioned inlet diffuser of chapter 5 hydrogenation engineering of " hydroprocessing technique and engineering " (the Li Dadong chief editor published the 797th page in 2004) and equipment is the inlet diffuser that the U.S. unites oily company hydrogenation reactor.Inlet diffuser is that medium enters first parts that reactor runs into, its effect is, (1) with the Medium Diffusion that enters to the whole cross section of reactor, (2) eliminate the vertical impact of gas-liquid medium to the top distribution plate, for the steady operation of distribution plate creates conditions; (3) impel gas-liquid two-phase to mix by disturbance; This inlet diffuser is a kind of double-layer porous plate structure, and the perforate size on the two-layer orifice plate is different with density.Reaction medium is diffused on the distribution plate of top after the throttling in two-layer hole, collision after the rectification of upper taper body.Studies show that this structure liquid measure under porous plate is very concentrated, gas-liquid logistics mixed effect is limited, is applicable to small-sized hydrogenation reactor; The effect of this diffuser is good, and the hydrogenation reactor of present domestic design adopts this form mostly.Commercial Application shows and can cause bias current and cause top bed inlet radial temperature difference bigger than normal in the major diameter hydrogenation reactor.
A kind of inlet diffuser that patent US4788040 proposes has a up-small and down-big conical entrance conduit, is provided with a unsteady flow cone over against the lower end of entry conductor, is provided with a plurality of splash plate in unsteady flow cone side.After the gas-liquid two-phase medium flowed out in the entry conductor, under the acting in conjunction of unsteady flow cone and a plurality of splash plate, liquid deflected, and was assigned on the distribution plate of below.The advantage of this inlet diffuser is simple in structure, and buffering effect is also better; Shortcoming is: under the acting in conjunction of unsteady flow cone and a plurality of splash plate, the amount of liquid phase of the direction that liquid deflects and the back all directions that deflect is difficult to control, so liquid phase bias current degree is bigger, and the peak value that liquid phase is radially distributed is also higher.
A kind of inlet diffuser that patent CN 100340331C proposes is made of outer cylinder body, base plate, cover plate, interior external conical-tube, forms annular space between inner conical-tube and the external conical-tube, offers the spiral line type flow-guiding mouth on the conical shell of inner conical-tube and external conical-tube.Change and be able to the buffer fluid impulse force at the baffle plate place direction of flow that is made of cover plate and base plate, gaseous stream enters inner conical-tube and sprays to annular space by flow-guiding mouth, and liquid phase stream enters annular space and sprays in reactor by the external conical-tube flow-guiding mouth.Because of the gas-liquid shunting, there is the shortcoming of gas-liquid logistics mixed effect difference.
A kind of inlet diffuser that patent CN 201042663Y proposes, be made up of inside and outside two cylinders, have several v-notch on inner cylinder top, inner cylinder top blind flange edge is corresponding also several gap slots, one stripe shape or porous type liquid separatnig plate are arranged at the inner cylinder bottom, disperse in order to fluid.Also there is the shortcoming of gas-liquid logistics mixed effect difference in this structure.
In sum, mainly there are following two shortcomings in the inlet diffuser that uses at present: (1) gas-liquid logistics incorporation time is short, undercompounding.(2) for the bigger situation of reactor diameter, inlet diffuser is difficult to material is dispersed to the entire top distribution plate equably, and the logistics that the logistics bias current has influenced distribution plate distributes performance.
