Abstract

A twin-ball column porcelain carrier is formed by combining two ball-crown bodies with the same diameter and the same column at two ends of a cylinder. A plurality of spherical bulges are uniformly distributed on the external surface of the two spherical crown bodies; a strip of through hole is provided along the direction of the two spires in the biconical porcelain carrier; thus effectively reducing the thermal capacity of the porcelain carrier, increasing the carrier specific surface, and increasing the cumulated clearance of the carrier so as to furthermore reduce the pressure losses through air or liquid flow, increasing the material migration rate and enhancing the efficiency of the catalytic reaction. As the fillings for supporting and protecting the catalyst, the utility model can be widely used for various reactors and fractionating devices in the fields of petrochemical industry, coal chemical industry and fine chemicals.

Description

Two goalpost shape ceramic carriers

Affiliated technical field

The utility model relates to a kind of catalyst carrier, especially a kind of two goalpost shape ceramic carriers that are used to support guard catalyst.

Background technology

At present; in the various reactors of petrochemical industry, Coal Chemical Industry, fine chemistry industry and fractionating device, all use the porcelain carrier; these porcelain carriers are used for supporting the catalyst of guard reactor; this just requires the porcelain carrier should have outside the high temperature resistant and higher mechanical strength, can play the effect that does not make catalyst poisoning and coking, fully filtration, dispersed gas liquid phase, covering and support catalyst simultaneously again.And the porcelain carrier that generally uses now mainly is spherical or cylindric, perhaps is exactly that outer surface spherical at these or column like catalyst carrier is opened a rule groove.These porcelain carrier processing are simple and easy, mechanical strength is also higher, add that to fill out reactor quick, but also there is obvious defects in they: the ceramic carrier thermal capacity of entity shape is big, it is long that catalyst reaches the operating temperature time, the catalyst adsorption strength is low, reaches that again temperature to be risen to after the temperature higher, thereby can reduce activity of such catalysts influence reaction; The bulk density height, the gap is little, and the pressure loss that filtration gas, liquid stream cause is big, and the material transport efficiency is low.And the porcelain carrier of other recessing of those outer surfaces, because the groove corner angle are too sharp-pointed, in filling and course of reaction, very easily cause wearing and tearing and form porcelain mud and make the effect of catalyst poisoning or reduction catalyst, facts have proved that these simple spherical or column like catalyst carrier all can cause harmful effect to catalyst or catalytic reaction.

Summary of the invention

In order to overcome the existing deficiency that porcelain carrier thermal capacity is big, bulk density is high, the gap is little and easy wearing and tearing come off, the utility model provides a kind of pair of goalpost shape ceramic carrier, not only mechanical strength is higher for it, add that to fill out reactor convenient, and specific area is big, thermal capacity is less, ventilation, the liquid phase pressure loss is little, and material mobility height helps improving catalytic reaction efficient.

The technical scheme that its technical problem that solves the utility model adopts is: the porcelain carrier is in conjunction with the formation of two diameters ball-crown body identical with cylinder diameter at cylinder two ends, on the outer surface of two ball-crown bodies, be evenly equipped with many ball bumps, in two goalpost shape ceramic carriers, have a through hole that runs through along two ball-crown body top orientation.

The utility model has following beneficial effect:

1, specific area strengthens (spherical relatively or column like catalyst carrier), and the catalyst adsorption strength improves.

2, thermal capacity reduces, and catalyst reaches the shortening of operating temperature time.

3, adopt the cambered surface transition on the carrier outer surface, antiwear property is strengthened, and can in use not form porcelain mud and damages catalyst.

4, under the identical situation of bulk density, clearance rate improves, and the pressure loss reduces during by gas, liquid stream, and the material mobility improves, and catalytic reaction efficient increases.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the two goalpost shape ceramic carrier stereograms of the utility model;

Fig. 2 is that the two ball type carrier masters of the utility model show view;

Fig. 3 is the A-A cutaway view of the two goalpost shape carriers of the utility model;

Among the figure: 1, porcelain body, 2, through hole, 3, ball bumps.

Embodiment

As shown in the figure, make two goalpost shape porcelain bodies (1) with Inorganic Non-metallic Materials, it is to constitute in conjunction with two diameter ball-crown bodies identical with cylinder at cylinder two ends, uniform many ball bumps (3) on the outer surface of two ball-crown bodies have a through hole that runs through (2) in this pair goalpost shape ceramic carrier inside along two ball-crown body top orientation.

Operation principle is as follows: annotate earlier in reaction unit and fill out the carrier layer that the different two goalpost shape carriers of size are formed, on this carrier layer, add attached catalyst layer then, on catalyst layer, cover the carrier layer that one deck is made up of two goalpost shape carriers again, add attached catalyst layer on it again, be repeated to specification requirement with this.Two like this goalpost shape ceramic carriers can be protected support catalyst, can make gas, liquid stream can conveniently pass gap between two goalpost shape carriers and through hole and the catalyst haptoreaction in the ceramic carrier again.Owing to adopted this structure, under the situation of identical bulk density, use two goalpost shape ceramic carriers than using simple spherical or cylindric carrier more can increase the carrier specific surface, reduce the thermal capacity of ceramic carrier, reduce the wearing and tearing between ventilation, liquid flowing pressure loss and carrier, improve the material transport efficiency, thereby reach the purpose that promotes that reaction is raised the efficiency.

Claims

1, a kind of pair of goalpost shape ceramic carrier, it includes two goalpost shape porcelain bodies (1) and the ball bumps on it (3), through hole (2), and it is characterized in that: two goalpost shape porcelain bodies (1) are to be made of in conjunction with two diameter ball-crown bodies identical with cylinder cylinder two ends.
