Abstract
The utility model provides an aluminium oxide trompil ball, it includes aluminium oxide trompil ball body (1), the surface of aluminium oxide trompil ball body (1) is equipped with spiral muscle (2) of radial evagination. Aluminium oxide trompil ball's surface is equipped with the spiral muscle, has increased the dynamic porosity, has reduced the bulk density, and it is effectual to distribute during the bed of reaction material process reactor layer, the increase of the reaction degree of depth, and the quality of product obtains improving.
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 processed stream flow resistance 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 logistics.
The scheme that the utility model adopts is:
A kind of aluminium oxide perforate ball, it comprises aluminium oxide perforate ball body, and the surface of described aluminium oxide perforate ball body is provided with the cambered outwards spiral bar in footpath.
As preferably, described spiral bar and aluminium oxide perforate ball body are structure as a whole.
The surface of aluminium oxide perforate ball is provided with continuous print, does not have the coiled-coil muscle of interruption, adds voidage, decreases bulk density, distribute effective when reactant flows through reactor layer bed, and reaction depth increases, and the quality of product is improved.
As preferably, the surface of described aluminium oxide perforate ball body has 1/4 to 3/4 for spiral bar.
The large percentage of spiral bar shared by alumina balls perforate ball body surface, make the surface relief of aluminium oxide perforate ball uneven, now on aluminium oxide perforate ball, offer through hole, through hole surrounding equally also can be rough and uneven in surface, when other perforate balls get lodged in through-hole surfaces, reactant fails to be convened for lack of a quorum from rough and uneven in surface and comes in and goes out, thus is not easy to cause plug-hole.
As preferably, described aluminium oxide perforate ball body is provided with at least 2 through holes.
As preferably, described aluminium oxide perforate ball body is provided with a spherical hollow space (4), the diameter of described spherical hollow space (4) be the 2-5 of through-hole diameter doubly.
The diameter of cavity is 2-5 times of through-hole diameter, and through hole consequently reduces the quality of aluminium oxide perforate ball on the one hand, and reduce accumulation quality, on the other hand, through hole adds the capacity that logistics enters through hole, reduces the flow resistance to logistics.
As preferably, described through hole is intersected in cavity.
Through hole is intersected in cavity, have in two gateways of one group of through hole one by Partial Blocking time, material can be come in and gone out from other one group of through hole by cavity.
The beneficial effects of the utility model are:
1, the surface of aluminium oxide perforate ball is provided with spiral bar, adds voidage, decreases bulk density, and reaction mass distributes effective through reactor layer bed, and reaction depth increases, and the quality of product is improved.
2, the large percentage of spiral bar shared by alumina balls perforate ball body surface, make the surface relief of aluminium oxide perforate ball uneven, now on aluminium oxide perforate ball, offer through hole, through hole surrounding equally also can be rough and uneven in surface, when other perforate balls get lodged in through-hole surfaces, reactant fails to be convened for lack of a quorum from rough and uneven in surface and comes in and goes out, thus is not easy to cause plug-hole.
3, through hole is intersected in the setting of cavity, and when having one to be blocked in two gateways of one group of through hole, material can be come in and gone out from other one group of through hole by cavity.
