Abstract
The invention discloses a catalyst carrier, which belongs to the technical field of the protection and supporting product structure of a fixed bed catalyst which is a solid catalyst product used in industries of oil refining, chemicals, gas processing and the like. The catalyst carrier comprises a central hole, a convex part, a top part, a cylinder, a concave part, a groove and a body, wherein the body comprises the cylinder and at least one convex part arranged around the cylinder, which are formed in one piece; the cylinder has a cylindrical solid structure, and a through central hole is arranged along an axial direction; and the at least convex part has a blade cylinder-shaped, toothed or arch cylinder-shaped solid structure, and the protruding top part of the at least one convex part is provided with at least one groove running through the axial direction. When the technical scheme of the invention is adopted, lateral loading capacity is improved, the intensity of lateral pressure is improved, the voidage of a supporting protective agent is improved, and the pressure drop of the bed of the catalyst is reduced.
Description
Technical field
The present invention relates to a kind of catalyst carrier; belong to the technical field of the solid catalyst product structure of the industries uses such as oil refining, chemical industry, gas treatment, belong to specifically the protection of fixed bde catalyst in the solid catalyst product and the technical field of support product structure.
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 the 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 large, has greatly affected the service efficiency of catalyst and device.Demand can realize reducing bed pressure drop, improves side pressure strength, effectively protects catalyst protection and the support product of the life cycle of major catalyst and extension fixture.
Summary of the invention
The invention provides a kind of catalyst carrier, can realize improving side pressure strength, reduce bed pressure drop, effectively protect the purpose of the life cycle of major catalyst and extension fixture.
For reaching described purpose technical scheme of the present invention be:
A kind of catalyst carrier is characterized in that, comprising: centre bore, lug boss, cylinder; The cylinder periphery is surrounded with at least one lug boss; Cylinder and lug boss are one-body molded; This cylinder is columned solid construction, and the through hole centre bore is set vertically; At least one lug boss is the solid construction of dentation or arc column shape, and adjacent two lug bosses are connected to form recess; The top of described at least one lug boss projection connects vertically at least one groove is set.
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.
This lug boss magnitude setting is 3-12.
This lug boss magnitude setting is 6.
This tongue vertically cross sectional shape is arc, V-arrangement.
This lug boss is the arc convex that contains at least one circle-shaped top.
Cylinder height is 15 millimeters, this cylinder excircle diameter is 16 millimeters, this center-hole diameter is 7 millimeters, the lug boss that should set gradually around the cylinder excircle is that tooth-shape structure and number are 6, it is 2.5 millimeters circle-shaped top that this lug boss contains 2 radiuses separately, the circle diameter at each lug boss convex top place is 30 millimeters, and this tooth-shape structure lug boss facewidth is 8.5 millimeters.
Adopt technical scheme of the present invention because: 1) existing support protective agent is spherical stressed for pressing, and it all is to only have a lifting-line that cylindricality and annular are sidelong when stressed.The present invention makes support protective agent lobate, and dentation or plum blossom column make 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 lug boss of cylinder get identical evenly so that the top of any two projections (plum blossom pillar) body when contacting with the bottom, can both keep enough through holes.3) offer a manhole in the axial centre of post (plum blossom pillar) body, to increase voidage.
Adopting the present invention 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
As follows to the detailed description of the invention below in conjunction with accompanying drawing:
Fig. 1, Fig. 2 are end face structure schematic diagram of the present invention and perspective view.A kind of catalyst carrier of the present invention comprises: centre bore 1, lug boss 2, top 3, cylinder 4, recess 5, groove 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 of its setting; This cylinder 4 is columned solid construction, and through hole centre bore 1 is set vertically, and this centre bore 1 optimum diameter is 7 millimeters; At least one lug boss 2 is the leaf column, the solid construction of dentation or arc column shape, and adjacent two lug bosses 2 are connected to form V-type recess 5; The top of described at least one lug boss 2 projection connects vertically at least one groove 6 is set, and this tongue 6 vertically cross sectional shape can be arc, V-arrangement or triangle.These body 10 thickness are the 3-50 millimeter, and the best is 15 millimeters; These cylinder 4 diameters are the 3-50 millimeter, and the best is 16 millimeters.
This at least one lug boss 2 that is shaped on the cylinder 4 is evenly to arrange successively or successively around cylinder 4 excircles, and magnitude setting is 3-12, and these lug boss 2 best magnitude settings are 6 tooth-shape structures.This lug boss 2 is for containing the arc convex at least one circle-shaped top 3.As among Fig. 1 being two circumference or two circular-arc projection, this pair circumference or two circular-arc protruding sandwich groove 6, the degree of depth of groove 6 can be the 1-4 millimeter.
At least one lug boss 2 is the solid construction of dentation or arc column shape, (so-called dentation is lug boss 2 to the solid cylinder of tooth-formation of gear shape), adjacent two lug bosses 2 are connected to form V-type recess 5, the lug boss 2 that namely evenly arranges successively or successively around cylinder 4 excircles whenever in twos lug boss 2 natural junctions all can form recess 5.Recess 5 in fact also is arranged on cylinder 4 external peripheral surfaces, and is even setting, because lug boss 2 evenly arranges successively at cylinder 4 excircles, the circumference that forms along the concave bottom of cylinder 4 at least one recess 5 like this is identical with cylinder 4 excircles.As Fig. 1 for these body 10 thickness be 15 millimeters, these cylinder 4 excircle diameters are 16 millimeters, this centre bore 1 diameter is 7 millimeters, the lug boss 2 that should set gradually around cylinder 4 excircles is that tooth-shape structure and number are 6, it is 2.5 millimeters circle-shaped top 3 that this lug boss 2 contains 2 radiuses separately, the circle diameter at each lug boss 2 convex top 3 place is 30 millimeters, and these tooth-shape structure lug boss 2 facewidth are 8.5 millimeters.
Product of the present invention adopts commercial alumina, clay and other raw mineral materials is prepared burden, mixing, ball milling, refinement treatment, extrusion molding in the extruder of the mould of chi shape design on request is housed, and drying is through making greater than 1000 ℃ high-temperature calcination.
