Description
Technical field
The present invention relates to the solid packing in a kind of chemical reaction tower, more particularly to a kind of special aluminum oxide perforate ball.
Background technology
Solid packing is may require that in chemical reaction tower, the voidage of increase filler is in the urgent need to address in industry asks
Topic, if voidage is small, causes transparent performance poor, so that the flow resistance of institute's process streams is big, easily causes logistics anti-
It is mixed, coking and the difference increase of packed bed laminate layer can be promoted, reactor normal operating is influenceed.Spherome surface is generally used in the prior art
The shallower bar that is raised or being increased above spherome surface of increase brings increase voidage, and these methods can actually be certain
Voidage is added in degree, heap density is reduced, distributed effect is good when reaction mass passes through reactor bed, reaction depth increases
Greatly, the quality of product is improved.However, filler particles put into reaction tower during, the position in reaction tower be with
Machine, the perforate of filler is probably blocked by the surface of another filler, and the effect in such duct weakens significantly.
Accordingly, it would be desirable to seek a kind of new technical scheme to solve the above problems.
The content of the invention
The purpose of the present invention is：A kind of special aluminum oxide perforate ball is provided.
To achieve the above object, the technical solution adopted by the present invention is：
A kind of special aluminum oxide perforate ball, including aluminum oxide perforate ball body, the surface of the aluminum oxide perforate ball body
Outwardly convex spiral bar is uniformly distributed, the two ends of the aluminum oxide perforate ball body are provided with hemispherical projections, the adjacent spiral shell
Revolve and groove be provided between muscle and spiral bar and hemispherical projections, the aluminum oxide perforate ball body provided with it is multipair run through it is logical
The connection between the filler inside groove of through hole, through hole and the filler inside groove is communicated with hole, the aluminum oxide perforate ball body
Passage is trapezoidal.
In the above-mentioned technical solutions, spiral bar, hemispherical projections and groove are used cooperatively, and can increase aluminum oxide perforate
Porosity between ball body, adds permeability；And the intrinsic filler internal slot diameter of aluminum oxide perforate ball is more than through hole, and
Pass through trapezoidal interface channel between the two to connect, it is to avoid the blocking of filler.
The spiral bar and aluminum oxide perforate ball body are formed in one structure.
The hemispherical projections and aluminum oxide perforate ball body are formed in one structure.
The diameter of the groove is less than the diameter of hemispherical projections.
In the above-mentioned technical solutions, hemispherical projections can be avoided to fill to groove, reduces porosity.
The diameter of the groove is less than the width of spiral bar.
In the above-mentioned technical solutions, spiral bar can be avoided to fill to groove, reduces porosity.
Brief description of the drawings
Accompanying drawing 1 is the front view of the embodiment of the present invention one.
In the figures above：1- aluminum oxide perforate balls body, 2- spiral bars, 3- hemispherical projections, 4- grooves, 5- through holes, 6-
Filler inside groove, 7- interface channels.
Embodiment
Below in conjunction with the accompanying drawings and embodiment the invention will be further described.
Embodiment one：
As described in Figure 1, a kind of special aluminum oxide perforate ball of the invention, including aluminum oxide perforate ball body 1, the oxidation
The surface of aluminium perforate ball body 1 is uniformly distributed outwardly convex spiral bar 2, and the two ends of the aluminum oxide perforate ball body 1 are provided with
Hemispherical projections 3, are provided with groove 4 between the adjacent spiral bar 2 and spiral bar 2 and hemispherical projections 3, the aluminum oxide is opened
Hole ball body 1 is provided with the filler inside groove 6 that through hole 5 is communicated with the multipair through hole 5 run through, the aluminum oxide perforate ball body 1,
Interface channel 7 between the through hole 5 and filler inside groove 6 is trapezoidal.
In the above-mentioned technical solutions, spiral bar 2, hemispherical projections 3 and groove 4 are used cooperatively, and can increase aluminum oxide
Porosity between perforate ball body 1, adds permeability；And the diameter of filler inside groove 6 in aluminum oxide perforate ball body 1 is more than
Through hole 5, and being connected between the two by trapezoidal interface channel 7, it is to avoid the blocking of filler.
The spiral bar 2 and aluminum oxide perforate ball body 1 are formed in one structure.
The hemispherical projections 3 and aluminum oxide perforate ball body 1 are formed in one structure.
The diameter of the groove 4 is less than the diameter of hemispherical projections 3.
In the above-mentioned technical solutions, it can avoid in convex 3 filling to the grooves 4 of hemispherical, reduce porosity.
The diameter of the groove 4 is less than the width of spiral bar 2.
In the above-mentioned technical solutions, spiral bar 2 can be avoided to fill to groove 4, reduces porosity.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art
Scholar can understand present disclosure and implement according to this, and it is not intended to limit the scope of the present invention.It is all according to the present invention
The equivalent change or modification that Spirit Essence is made, should all be included within the scope of the present invention.
