Abstract
The utility model relates to a perforated alumina ball, which comprises a sphere and a through hole. The diameter of the sphere 1 is 6 mm to 50 mm, and one to nine straight through holes are homogeneously distributed on the sphere. The hole diameter of the straight through hole is 1.8 mm to 8 mm. Transverse through holes which are perpendicular to the straight through holes can also be arranged, the pore diameter of the transverse through holes is 1 mm to 5 mm, and the number of the transverse through holes is one to nine. The bulk density of the utility model can be lowered by 20 % to 50 % compared with a solid ball, and the external surface of the utility model can be increased by 20% to 70% compared with the solid ball. The aspects of the porosity of the heat transfer property and bed resistance can be obviously improvement. Because each direction of openings are uniform, stress concentration problem can be avoided, and stable strength in operation process can be realized.
Description
The utility model relates to a kind of filler that is used for petrochemical industry, particularly a kind of perforate alumina balls.
Alumina balls are rebasing, supporting, the interlayer fillers in the equipment such as conversion, reaction, absorption that is applied in the petrochemical industry industry, the employed alumina balls proportion of above-mentioned each equipment is more than every liter of 1.5-2.5 kilogram at present, be that a kind of bulk density is big, the low filler than showing, and owing to be solid sphere, cause SR big, increase energy consumption.
The purpose of this utility model is to provide a kind of particle regular, the perforate alumina balls that bulk density is low.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is: comprise spheroid 1 and through hole 2; Described spheroid 1 diameter is the 6-50 millimeter, 1-9 the clear opening 2 that on this spheroid 1, distributing, and described clear opening 2 apertures are the 1.8-8 millimeter; Can also be provided with the aperture and be 1-5 millimeter, number and be the perpendicular horizontal through hole 3 of 1-9 and described clear opening 2.
Owing to have clear opening and horizontal through hole on the spheroid of perforate alumina balls of the present utility model, make original solid sphere become the porous spheroid, its bulk density reduces by 20～50%, outer surface increases 20-70%, to the conductivity of heat voidage, the bed resistance aspect can be significantly improved and since in perforate each to evenly, unstressed concentration problem, in use intensity stabilization.
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is the utility model profile schematic diagram;
Fig. 2 is that A-A is to cutaway view.
As shown in the figure, comprise spheroid 1 and through hole 2; Described spheroid 1 diameter is 35 millimeters, is uniform-distribution with 7 clear openings 2 on this spheroid 1, and described clear opening 2 apertures are 5 millimeters; Also be provided with 3 apertures and be 4 millimeters, with the perpendicular horizontal through hole 3 of described clear opening 2.
Another embodiment of the present utility model is: described spheroid 1 is replaced by cylinder, simultaneously be uniform-distribution with the clear opening 2 that diameter is the 1.8-8 millimeter, can also be provided with the aperture and be 1-5 millimeter, number and be the perpendicular horizontal through hole 3 of 1-9 and described clear opening 2 at this cylinder upper edge axis.
Claims (3)
1, a kind of aluminium oxide perforate ball comprises spheroid (1) and through hole (2); It is characterized in that described spheroid (1) diameter is the 6-50 millimeter, 1-9 the clear opening (2) that on this spheroid (1), distributing, described clear opening (2) aperture is the 1.8-8 millimeter.
2, aluminium oxide perforate ball as claimed in claim 1, it is characterized in that also being provided with the aperture and be 1-5 millimeter, number and be 1-9 with the perpendicular horizontal through hole (3) of described clear opening (2).
