CN2317936Y - Ball-shaped filler with multiple parallel channels - Google Patents

Abstract

The utility model relates to ball-shaped filler with multiple parallel channels. The utility model is composed of a filler granule solid and cylindrical hole channels which are arranged on the surface of the granule solid and are respectively provided with two openings. The number of the hole channel is two at least, and the hole channels are parallel. The shape of the hole channel forms a cylinder shape. The utility model has the advantages of light weight, good permeation performance, etc. The utility model is used for the filler for petrochemical industry reaction towers.

Description

A kind of Ball-type packing with a plurality of parallel ducts

The utility model relates to a kind of solid packing in oil, chemical industry and the coal refining reaction tower.This filler is seated in bottom and the top in the reaction tower, and what loaded at the middle part is catalyst.At present, employed filler is generally sial porcelain ball in the industrial reaction tower.Owing to be a kind of solid, the intergranular space rate is little, causes transparent performance poor, thereby makes institute's process streams flow resistance increase, and causes the logistics back-mixing easily, consequently promotes coking and filling batch pressure reduction to increase, and influences the reactor normal running.

Chinese patent (utility model) ZL94217136.5 discloses a kind of porous ball cylindricality filler, and this filler is made up of porcelain body and porcelain hole, promptly offers the hole (as shown in Figure 1) of certain pore size at porcelain ball or porcelain knob center.

This filler is compared with the solid filler with identical particle shape and volume and same material, and weight reduces, and transparent performance is good, and what have improved the serviceability of solid filler.

But, filler particles in putting into the reaction tower process in reaction tower the present position be at random, when the aperture of Ball-type packing particle contacts with the surface of another particle, the effect in duct will weaken greatly, act on as the duct of the bead above Fig. 1 and have a greatly reduced quality.

The purpose of this utility model is the shortcoming at above-mentioned single Pored ceramic ball, provides a kind of transparent performance good, the Ball-type packing little to the Flow of Goods and Materials resistance.

Main points of the present utility model are to offer the duct of a plurality of two ends at the particle surface opening on the particle of Ball-type packing, and these a plurality of ducts are parallel to each other.The duct shape is preferably cylindricality, is more preferably cylindrical.The pore size in filler particle size, duct and duct number are determined by the instructions for use of filler.The pore size in a plurality of ducts is not wait.Aperture, the duct maximum at particle center, and more little the closer to the grain edges aperture.This is because particle central duct length is longer, so increase its aperture to reduce its flow resistance.The filler material is a heat-resistant inorganic oxide, can be various natural claies, also can be artificial synthetic aluminium oxide, or contains the aluminium oxide of other inorganic elements.

It is simple that advantage of the present utility model is that (1) makes, and promptly can be made into as long as change mould structure; (2) voidage height, transparent performance is good; (3) owing to offer a plurality of parallel ducts, can only be stopped up by other particle surfaces in spheric granules is piled up in an aperture at most, permeation still can be brought into play in other ducts, as shown in Figure 2.(4) owing to little to the stream flow resistance, in the high-temperature hydrogenation reaction tower, can highly suppress the coking reaction, improve the catalytic effect of catalyst.

Claims (3)

1. perforate Ball-type packing is made up of filler particles entity and the duct that has two openings on the particle solid object surface, it is characterized in that at least two in described duct and parallel to each other.

2. according to the described filler of claim 1, it is characterized in that described duct is cylindrical.

3. according to claim 1 or 2 described fillers, it is characterized in that the pore size in described a plurality of ducts does not wait, aperture, the duct maximum at particle center is more little by the grain edges aperture more.
