Description
Technical field
The utility model relates to a kind of porous plum blossom cylindricality catalyst carrier; belong to the technical field of the solid catalyst product structure of industries uses such as oil refining, chemical industry, gas treatment, belong to the protection of fixed bde catalyst in the solid catalyst product and the technical field of support product structure specifically.
Background technology
At present, the shape of the support protective medium structure of existing beds has sphere, Raschig ring, hollow impeller, porous ball and porous circular cylinder etc. in industries such as oil refining, chemical industry, gas treatment.Their major defect is: 1) side pressure strength is low, and is damaged easily; 2) voidage is low, and bed resistance is big, has greatly influenced the service efficiency of catalyst and device.Demand can realize reducing bed pressure drop, improves side pressure strength, effectively protects the catalyst protection and the support product of the life cycle of major catalyst and extension fixture.
The utility model content
The utility model provides a kind of porous plum blossom cylindricality catalyst carrier, can realize improving side pressure strength, reduces bed pressure drop, effectively protects the purpose of the life cycle of major catalyst and extension fixture.
For reaching described purpose the technical solution of the utility model be:
A kind of porous plum blossom cylindricality catalyst carrier is characterized in that, comprising: centre bore, lug boss, cylinder, leaf hole; The cylinder periphery is surrounded with at least one lug boss; Cylinder and lug boss are one-body molded; This cylinder is a solid construction, along this cylinder axis to the through hole centre bore is set; At least one lug boss is the solid construction of arc column shape, and at least one through hole leaf hole is set on this lug boss, and adjacent two lug bosses are connected to form recess.
Cylinder height is the 3-50 millimeter, and diameter is the 3-50 millimeter.
This is shaped at least one lug boss on the cylinder for to set gradually around the cylinder excircle.
It is 3-12 that this lug boss is provided with quantity.
This leaf hole around centre bore in the form of a ring or circle-shaped even setting.
The cylinder height is 15 millimeters, this center-hole diameter is 4 millimeters, the lug boss number that should set gradually around the cylinder excircle is that the leaf hole circle heart place circle diameter that is provided with on 5 and each lug boss is 12 millimeters, this lug boss arc radius separately is 4 millimeters, and the circle diameter at each lug boss projection peak place is 20 millimeters.
Adopt the technical solution of the utility model because:
1) existing support protective agent is spherical presses stressedly for point, and it all is to have only a lifting-line that cylindricality and annular are sidelong when stressed.The utility model is that support protective agent is made the similar quincuncial column of porous, makes it to be sidelong when stressed, and two above lifting-lines are arranged at bottom or top, have increased load-carrying ability, have improved side pressure strength.
2) size design of each petal of plum blossom post get identical evenly, when making the petal top of any two plum blossom cylinders contact, can both keep enough through holes with the bottom.
3) offer a manhole in the axial centre of plum blossom cylinder, also offer through hole on each petal (lug boss), to increase voidage.Adopting porous plum blossom post to reach increases the side pressure bearing capacity, has improved side pressure strength; The size design of petal and axial aperture can improve the voidage of support protective agent, reduce the effect of the pressure drop of beds.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail as follows: Fig. 1, Fig. 2 are end face structure schematic diagram of the present utility model and perspective view.The utility model porous plum blossom cylindricality catalyst carrier comprises: centre bore 1, lug boss 2, top 3, cylinder 4, recess 5, leaf hole 6 and body 10 as shown in Figure 1 and Figure 2.Described body 10 is by cylinder 4 and one-body molded around at least one lug boss 2 that is provided with; This is shaped at least one lug boss 2 on the cylinder 4 for to set gradually around cylinder 4 excircles.It is 3-12 that this lug boss 2 is provided with quantity, and lug boss 2 optimum number that should set gradually around cylinder 4 excircles are 5 (as Fig. 1).
This cylinder 4 is columned solid construction, along this cylinder 4 through hole centre bore 1 is set axially; This centre bore 1 optimum diameter is 4 millimeters.At least one lug boss 2 is a solid construction cylindric or the arc column shape, and these lug boss 2 upper edge end face axial are provided with at least one through hole leaf hole 6.Adjacent two lug bosses 2 are connected to form V-type recess 5.These body 10 thickness are the 3-50 millimeter; These cylinder 4 diameters are the 3-50 millimeter.These body 10 optimum thicknesses are 15 millimeters, and this leaf hole 6 around centre bore 1 in the form of a ring or circle-shaped even setting (as Fig. 1).And the best circle diameter in the place, 6 center of circle, leaf hole that is provided with on each lug boss 2 is 12 millimeters, and this lug boss 2 radius the best separately is 4 millimeters, and the best circle diameter at each lug boss 2 convex top 3 place is 20 millimeters.
