Abstract
The utility model relates to a sphere-cylindrical ceramic carrier, which is a combination structure of a cylinder and spherical cap bodies. Namely, the middle part forms a cylinder shape, and both ends are spherical cap bodies. A plurality of grooves are evenly distributed on the cylindrical surface of the cylinder, and a through hole is arranged between the spherical cap bodies and penetrates through the cylinder. The utility model can effectively reduce the heat capacity of the ceramic carrier, increasing the specific surface area of the ceramic carrier, reducing the pressure loss of ventilation liquid flow, increasing the mobility of substances, and enhancing the catalytic reaction efficiency. Simultaneously, as filling material for supporting and protecting catalyst, the utility model can be widely used for various reactors and fractionation devices of the petroleum chemical industry field, the coal chemical industry field and the fine chemical industry field, and can also be used for the automobile end gas processing and environmental protection field.
Description
The utility model relates to a kind of catalyst carrier, especially a kind of porcelain carrier that is used to support guard catalyst.
At present, matching requirements such as petrochemical industry, Coal Chemical Industry, the various reactors of fine chemistry industry and fractionation use the ceramic carrier of many specifications, this ceramic carrier has high temperature resistant and high mechanical properties, play again simultaneously and do not make catalyst poisoning and sintering, filter, disperse the effect of gas-liquid, covering and support catalyst.The ceramic carrier shape of generally using mainly contains cylindric and spherical two kinds, these granular ceramic carrier handling eases, mechanical strength height now, add embankment just, but have open defect on its performance: the thermal capacity of ceramic carrier is big, and heat impact strength is relatively poor, and it is long that catalyst reaches the operating temperature time; Specific surface is little, and the catalyst adsorption strength is low; Bulk density is big, and the gap is little, and the pressure loss that aeration liquid stream causes is big, and the material transport efficiency is low.Practice shows that these cylindric, spherical ceramic carriers can influence the efficient of catalytic reaction.
The purpose of this utility model provides a kind of ceramic carrier simple in structure, and it is handling ease not only, and the mechanical strength height adds embankment just, and specific surface is big, and thermal capacity is little, the ventilation liquid flowing pressure loss is little, material mobility height.
In order to achieve the above object, ceramic carrier of the present utility model adopts the design of goalpost shape, and adds ball-crown body at the cylinder two ends, has groove on the face of cylinder of cylinder equably, opens the hole through cylinder between two ball-crown bodies.
Compared with prior art, the utility model has following characteristics:
One, specific surface is big, catalyst adsorption strength height.
Two, thermal capacity is little, heat impact strength good, and it is short that catalyst reaches the operating temperature time.
Three, under the identical situation of bulk density, the ventilation liquid flowing pressure loss is little, material transport efficiency height, catalytic reaction efficient increases.

Fig. 6 is that the utility model goalpost shape ceramic carrier groove is that the B-B of swallow-tail form cuts open figure.
Fig. 7 is the utility model goalpost shape ceramic carrier fundamental diagram.
Below in conjunction with accompanying drawing and specific implementation method the utility model is described in further detail.
Embodiment one:
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 7, the utility model includes porcelain cylinder 1 and the ball-crown body made from silica, alchlor or titanium dioxide 4, difference is to be evenly equipped with 8 square grooves 2 on the face of cylinder of cylinder 1, passes cylinder 1 and have through hole 3 between two ends ball-crown body 4.
Operation principle is as follows: annotate to fill out by size earlier in reaction unit 5 the goalpost shape ceramic carrier that varies in size is formed carrier layer 6; add catalyst layer 7 then; cover the carrier layer of forming by the different goalpost shape ceramic carrier of size 6 again; ceramic carrier can be protected a palm catalyst 7 like this; can make gas-liquid flow can conveniently pass groove 2 again; gap between through hole 3 and carrier and the carrier and catalyst reaction; owing to adopted this structure; under the situation of identical bulk density, use goalpost shape ceramic carrier than using simple cylindrical vector or ball type carrier more can increase the carrier specific surface; reduce thermal capacity; reduce the ventilation liquid flowing pressure loss and improve the material transport efficiency, thereby reach the purpose that promotes reaction.
Embodiment two
Basic structure is identical with embodiment one with operation principle, and just groove 2 is the T font as shown in Figure 4.
Embodiment three
Basic structure is identical with embodiment one with operation principle, and just groove 2 is circular arc as shown in Figure 5.
Embodiment four
Basic structure is identical with embodiment one with operation principle, and just groove 2 is swallow-tail form as shown in Figure 6.
