Abstract
The utility model discloses a liquid raw oil redistributor which comprises a center layer (2), at least one interlayer (4) and an outer layer (6), wherein the center layer (2) is made of honeycomb ceramics and is arranged in a supporting grating (7); the number of center layer honeycomb holes (1), the number of interlayer honeycomb holes (3) and the number of outer layer honeycomb holes (5) in the center layer, the interlayer and the outer layer are the same; and the surfaces of the center layer honeycomb holes (1), the interlayer honeycomb holes (3) and the outer layer honeycomb holes (5) are provided with glazed layers (8). The liquid raw oil redistributor is made of ceramics with the high-density honeycomb holes of which the lowest density is more than 10 meshes, the honeycomb holes are the same from the center to the edge, and the glaze layers are arranged on the surfaces of the honeycomb holes, therefore, after liquid raw oil enters the redistributor to be redistributed, when the liquid raw oil enters a main agent layer, the parsing times of water spots of the liquid raw oil are greatly improved, the flowing distribution is more uniform and more compact, and uniform distribution of the liquid raw oil can be formed so that the reaction effect of the liquid raw oil is improved and the catalyzing efficiency of a main agent is improved.
Description
Technical field
The utility model relates to the distributor in the petrochemical industry smelting reactor, especially relates to a kind of reactor liquid material oil redistributor that is used for.
Background technology
In the petrochemical industry smelting process, liquid material oil enters back liquid expansions that fails to be convened for lack of a quorum from reactor head, so generally all is provided with distribution plate in reactor head.But existing distribution plate one is can only be liquid distribution into strips, and liquid spraying density into strips can directly have influence on the distribution character of feedstock oil, particularly metallic distribution plate is subjected to its molding mode restriction and can not forms big sprinkle density, thereby liquid material oil its water spot analysis number of times when entering the host layer can not be improved; The 2nd, existing distribution plate makes liquid material oil form the state that is reduced gradually out to the marginal flow kinetic force by the center, flow resistance increases gradually, thereby make the flow distribution of liquid material oil when entering the host layer just evenly little, can not make liquid material oil when entering the host layer, form fine and close more uniform distribution, thereby influence the reaction effect of liquid material oil, reduce the host catalytic efficiency.
The utility model content
At the problem that above-mentioned prior art exists, the utility model provides a kind of and has made liquid material oil be fine and close evenly the distribution to enter the host layer, help improving the liquid material oil redistributor of liquid material oil reaction effect and host catalytic efficiency.
The technical scheme that problem to be solved in the utility model is taked: described liquid material oil redistributor comprises with ceramic honey comb makes and is arranged on central core, at least one interlayer and skin in the supportive grid, central core honeycomb hole in described central core, interlayer and the skin, interlayer honeycomb hole are identical with outer honeycomb hole order number, are formed with uniform netted honeycomb hole in the described liquid material oil redistributor.
The utility model is owing to adopt the pottery with minimum density high density honeycomb hole more than 10 orders to make, and it is identical to edge honeycomb hole order number from the center, the honeycomb hole surface is provided with glazed layer, after liquid material enters the redistributor distribution, liquid material oil its water spot analysis number of times when entering the host layer is improved greatly, flow distribution when entering the host layer is just more even, make liquid material oil when entering the host layer, can form the more uniform distribution of densification, thereby improved the reaction effect of liquid material oil, improved the host catalytic efficiency.
Description of drawings
Fig. 1 is a plan structure schematic diagram of the present utility model,
Fig. 2 is the A-A cutaway view of Fig. 1.
Central core honeycomb hole 2, central core 3, interlayer honeycomb hole 4, interlayer 5, outer honeycomb hole 6, outer 7, supportive grid 8, glazed layer in the drawings, 1,
The specific embodiment
In Fig. 1 and Fig. 2, one deck central core 2 that described liquid material oil redistributor is made with ceramic honey comb, one layer interlayer 4 and one deck outer 6 formed, described interlayer also can be two-layer or more multi-layered, described central core, central core honeycomb hole 1 on interlayer and the skin, interlayer honeycomb hole 3 is identical with outer honeycomb hole 5 order numbers, described central core honeycomb hole 1, interlayer honeycomb hole 3 and outer honeycomb hole 5 are hexagonal hole, certainly also can be circular hole, square hole, the hole of tri-angle-holed or other shape, described central core honeycomb hole, the interlayer honeycomb hole can be identical with outer honeycomb hole shape, also can be inequality, described central core, interlayer and outer being separately positioned on the supportive grid 7 that stainless steel makes, supportive grid is that a bottom surface grid and three concentric annular grids form, fill central core respectively in three annular grids, interlayer and skin make in the liquid material oil redistributor and form uniform honeycomb hole.For preventing that better after liquid material oil redistributor from using honeycomb hole not taking place stops up, and adopts dip-coating or all honeycomb hole surfaces of spraying method to be provided with glazed layer 8, described glazed layer thickness 0.8-1.5mm.。
Claims (2)
1. liquid material oil redistributor, it is characterized in that: it comprises with ceramic honey comb makes and is arranged on the interior central core (2) of supportive grid (7), at least one interlayer (4) and outer (6), central core honeycomb hole (1) in described central core, interlayer and the skin, interlayer honeycomb hole (3) are identical with outer honeycomb hole (5) order number, are formed with uniform netted honeycomb hole in the described liquid material oil redistributor.
2. liquid material oil redistributor according to claim 1, it is characterized in that: described central core honeycomb hole (1), interlayer honeycomb hole (3) and outer honeycomb hole (5) surface are provided with glazed layer (8).
