Abstract
The utility model provides a take bellied aluminium oxide trompil ball, it includes aluminium oxide trompil ball body (1), the surface of aluminium oxide trompil ball body (1) is equipped with a plurality of more than half ball -types protruding (2), more than half ball -type protruding (2) tall and big in the radius, the diameter of more than half ball -type protruding (2) equals, there is the interval between more than half ball -type protruding (2), the spaced distance is less than the diameter of more than half ball -type protruding (2). The utility model aims at providing an aluminium oxide trompil ball can improve the permeability, reduces the flow resistance to the material.
Description
Technical field
The utility model relates to the solid packing in a kind of chemical reaction tower, is specifically related to a kind of aluminium oxide perforate ball.
Background technology
Solid packing can be needed in chemical reaction tower, the voidage increasing filler is problem in the urgent need to address in industry, if voidage is little, then cause transparent performance poor, thus make the flow resistance of institute's process streams large, easily cause logistics back mixing, can promote that coking and packed bed pressure layer difference increase, affect reactor normal operating.
Usually the milder projection of spherome surface increase or the bar increased higher than spherome surface is adopted to bring increase voidage in prior art, these methods can add voidage really to a certain extent, decrease bulk density, reaction mass distributes effective through reactor bed, reaction depth increases, and the quality of product is improved.
But filler particles is in the process putting into reaction tower, and the position in reaction tower is random, and the perforate of filler is probably blocked by the surface of another filler, and the effect in such duct weakens greatly.
Utility model content
The purpose of this utility model is to provide a kind of aluminium oxide perforate ball, can improve permeability, reduce the flow resistance to material.
The scheme that the utility model adopts is:
With a protruding aluminium oxide perforate ball, it comprises aluminium oxide perforate ball body, and it is protruding that the surface of described aluminium oxide perforate ball body is provided with multiple large dome-type, described large dome-type projection tall and big in radius, the equal diameters of described large dome-type projection; Have interval between described large dome-type projection, the distance at described interval is less than the diameter of described large dome-type projection.
As preferably, described aluminium oxide perforate ball body offers some first through holes.
Large dome-type is provided with protruding on the surface of aluminium oxide perforate ball, the height of large dome-type projection is greater than its radius, interval is had between projection, the distance at described interval is less than the diameter of described large dome-type projection, distance due to interval is less than the diameter of large dome-type projection, the large dome-type that the large dome-type projection that same aluminium oxide perforate ball is adjacent can block adjacent aluminium oxide perforate ball is protruding, make it the surface not reaching aluminium oxide perforate ball, more have no chance to block through hole, add voidage, decrease bulk density, reaction mass distributes effective through reactor bed, reaction depth increases, the quality of product is improved.
The setting of large dome-type projection too increases specific area, adds voidage, decreases bulk density.
As preferably, described aluminium oxide perforate ball body and large dome-type projection are structure as a whole.
As preferably, described large dome-type projection offers some second through holes.
Dome-type projection offers through hole, increases voidage, reduces bulk density.
The beneficial effects of the utility model are:
1, large dome-type is provided with protruding on the surface of aluminium oxide perforate ball, the height of large dome-type projection is greater than its radius, interval is had between projection, the distance at described interval is less than the diameter of described large dome-type projection, distance due to interval is less than the diameter of large dome-type projection, the large dome-type that the large dome-type projection that same aluminium oxide perforate ball is adjacent can block adjacent aluminium oxide perforate ball is protruding, make it the surface not reaching aluminium oxide perforate ball, more have no chance to block through hole, add voidage, decrease bulk density, reaction mass distributes effective through reactor bed, reaction depth increases, the quality of product is improved.
2, dome-type projection offers through hole, increases voidage, reduces bulk density.
Accompanying drawing explanation
Fig. 1 is the specific embodiment sectional view of embodiment 1 of the present utility model;
Fig. 2 is the schematic diagram of embodiment 1 of the present utility model;
1, aluminium oxide perforate ball body; 2, large dome-type is protruding; 3, the first through hole; 4, the second through hole;
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, with a protruding aluminium oxide perforate ball, it comprises aluminium oxide perforate ball body 1, and the surface of described aluminium oxide perforate ball body 1 is provided with multiple large dome-type projection 2, the height of large dome-type projection is greater than its radius, the equal diameters of described large dome-type projection 2; Have interval between described large dome-type projection 2, the distance at described interval is less than the diameter of described large dome-type projection 2, described aluminium oxide perforate ball body 1 offers multiple first through hole 3, described large dome-type projection 2 offers multiple second through hole 4.
Principle illustrates: as shown in Figure 2, when the aluminium oxide perforate ball of two band projections is adjacent, distance due to the interval between large dome-type projection 2 is less than the diameter of described large dome-type projection 2, the protruding shelves of the protruding large dome-type by the aluminium oxide perforate ball of adjacent band projection of two large dome-types of the aluminium oxide perforate ball that same band is protruding are lived, make it can not with the surface contact of aluminium oxide perforate ball body, more can not block through hole.
Above-described embodiment of the present utility model can not be used for limiting the utility model to explanation of the present utility model, and any change in the implication suitable with claims of the present utility model and scope, all should think to be included in the scope of claims.
