Abstract
The utility model provides a take aluminium oxide trompil ball of recess, it includes aluminium oxide trompil ball body (1), the surface of aluminium oxide trompil ball body (1) is equipped with recess (2), recess (2) are the toper structure that outer imperial palace is little, the cross section of recess (2) is triangle -shaped or the quadrangle is oval or quincunx, the bottom of recess is equipped with through -hole (3), the cross section of through -hole is circular. Aluminium oxide trompil ball is the spheroid, and spheroidal arbitrary cross section no. 1 is decided to be circular, adjacent aluminium oxide trompil ball when stopping up the through -hole, and the cross section of opening face of recess be non -circular this moment, because non -circular breach can not be stopped up totally to the circular shape plug, so can not stop up the through -hole totally to circulate in the clearance of the through -hole that the material still can never be stopped up.
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 with groove.
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.
Summary of the invention
The purpose of this utility model is to provide a kind of aluminium oxide perforate ball, can improve permeability, reduce the flow resistance to logistics.
The scheme that the utility model adopts is:
A kind of aluminium oxide perforate ball with groove, the surface that it comprises aluminium oxide perforate ball body described in aluminium oxide perforate ball body is provided with groove, described groove is the pyramidal structure that outer imperial palace is little, the cross section of described groove is that triangle or quadrangle are oval or quincunx, the bottom of described groove is provided with through hole, and the cross section of described through hole is circular.
Aluminium oxide perforate ball is spheroid, the arbitrary cross section one of spheroid is decided to be circle, when through hole blocked by adjacent aluminium oxide perforate ball, now the cross section of the opening surface of groove is non-circular, because the tamper of circle can not block non-circular breach completely, therefore can not block through hole completely, thus circulate in the gap of through hole that still can never block of material.
As preferably, described through hole is 2, and described through hole is parallel to each other.
As preferably, described two groups of through holes are interconnected, in " Z " type or " H type ".
Two groups of through holes are interconnected, and when wherein one group of through hole is by Partial Blocking, can circulate from other through holes.
The beneficial effects of the utility model are:
1, aluminium oxide perforate ball is spheroid, the arbitrary cross section one of spheroid is decided to be circle, when through hole blocked by adjacent aluminium oxide perforate ball, now the cross section of the opening surface of groove is non-circular, because the tamper of circle can not block non-circular breach completely, therefore can not block through hole completely, thus circulate in the gap of through hole that still can never block of material.
2, two groups of through holes are interconnected, and in " Z " type or " H type ", when wherein one group of through hole is by Partial Blocking, can circulate from other through holes.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Embodiment 1
As shown in Figure 1, Figure 3, a kind of aluminium oxide perforate ball with groove, it comprises aluminium oxide perforate ball body 1, described aluminium oxide perforate ball body 1 is provided with 2 through holes, and the cross section of described through hole is circular, and described two through holes are parallel to each other, described two groups of through holes are interconnected, in " Z " type.The top of each through hole of described aluminium oxide perforate ball body 1 is respectively provided with the little conical socket 2 of an outer imperial palace, and amount to 4 grooves (wherein two grooves 2 do not manifest in the drawings), the cross section of described 4 grooves 2 is triangle.
Embodiment 2
As shown in Figure 2, Figure 4 shows, a kind of aluminium oxide perforate ball with groove, it comprises aluminium oxide perforate ball body 1, described aluminium oxide perforate ball body 1 is provided with 2 through holes, and the cross section of described through hole is circular, and described two through holes are parallel to each other, described two groups of through holes are interconnected, in " H " type.The top of each through hole of described aluminium oxide perforate ball body 1 is respectively provided with the little conical socket 2 of an outer imperial palace, amount to 4 conical sockets (wherein two grooves 2 do not manifest in the drawings), wherein the cross section of 2 grooves 2 is triangle, and the cross section of other 2 grooves 2 is quadrangle.
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.
