Preferably, on described rotary body, there is 1-10 feeding mouth.
Preferably, described feeding mouth is around the central axis of described rotary body along being circumferentially evenly distributed on described rotary body.
Preferably, between described feeding mouth bearing of trend and described rotary body central axis, be formed with angle.
Preferably, described angle is 15-90 degree.
Preferably, on described flow-guiding structure, be provided with guiding gutter, the setting position of this guiding gutter is corresponding with described feeding mouth.
Preferably, described return guide trough becomes curved surface, between described curved surface, forms fin.
Preferably, described fin converges becomes a summit.
Pass through technique scheme, the utility model utilize into protrude from described spout dorsad flow-guiding surface material is guided to the flow-guiding structure of described feeding mouth, material can be distributed equably in described rotary body, thereby make the length of the mist distance that sprayed by described particle nozzle suitable, distribution space appropriateness, thereby reach, make that produced catalyst granules does not break, do not subside, adhesion is few, and epigranular, sphericity are higher, smooth surface.
Other feature and advantage of the present utility model partly in detail are described the specific embodiment subsequently.

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is elaborated.Should be understood that, the specific embodiment described herein only, for description and interpretation the utility model, is not limited to the utility model.
In the utility model, in the situation that not doing contrary explanation, the noun of locality of use typically refers to reference to upper and lower, left and right shown in the drawings as " upper and lower, left and right "; " inside and outside " refers to inside and outside with respect to the profile of each parts itself.
The utility model provides a kind of prilling nozzle, this prilling nozzle comprises having the nozzle body of cavity and be arranged on rotary body 20 and the spout in described nozzle body, described rotary body 20 has feeding mouth 21 and flow-guiding structure 22, this flow-guiding structure 22 be formed with protrude from described spout dorsad flow-guiding surface material is guided to described feeding mouth 21, thereby can the material for the manufacture of catalyst be imported in rotary body equably, make material in nozzle, be not easy to produce flow dead, solid phase particles can be because of deposition fouling, flocculation, thereby reduce widely the possibility of local caking.
The described flow-guiding surface of described flow-guiding structure can be arranged to a plurality of, and its quantity was both set according to the quantity of described feeding mouth, also can set according to actual needs.For example, two public described flow-guiding surface of feeding mouth 21.
As a kind of specific embodiment, on described rotary body 20, there is 1-10 feeding mouth 21.Preferably with the even numbers such as 2,4,6,8, arrange, the material in rotary body 20 can be uniformly distributed relatively.Particularly be arranged to as illustrated in fig. 38 so that the structural optimization of nozzle.
As a kind of specific embodiment, described feeding mouth 21 is circumferentially evenly distributed on described rotary body 20 around the central axis edge of described rotary body 20, thereby can make further to import in rotary body equably in the material of manufacturing catalyst.
Particularly, as shown in Figure 2, between described feeding mouth 21 bearing of trends and described rotary body 20 central axis, be formed with angle.Described angle is labeled as a, and the diameter of this feeding mouth is S.Common described feeding mouth 21 is arranged on described rotary body 20 obliquely, and the surface configuration of described feeding mouth 21 forms ellipse.Thereby not only can play guide effect to entering into feeding mouth 21 Raws of described inclination, but also larger entrance can be provided, so that raw material can easily enter into described rotary body.
Preferably, described angle is 15-90 degree.That is to say, it is also corresponding formation that surface configuration forms formed angle and described angle between the major axis of oval-shaped feeding mouth and the diameter of rotary body.In addition, preferred described angle is 30 degree.
As a kind of preferred specific embodiment, on described flow-guiding structure 22, be provided with guiding gutter, the setting position of this guiding gutter is corresponding with described feeding mouth 21.That is to say, as shown in Figure 3-4, the flow-guiding surface of described flow-guiding structure forms guiding gutter, along described rotary body plane, described guiding gutter is dissectd, and described guiding gutter cross section can be various shapes, such as circular arc, triangle etc.
Preferably, described return guide trough becomes curved surface, between described curved surface, forms fin.That is to say, while dissecing like that as described above, described cross section forms curve, and the intersection point between described a plurality of curves extends becomes above-mentioned fin.Meanwhile, described fin also equates with above-mentioned angle with the formed angle of central axis of described rotary body 20.
More preferably, described fin converges and becomes a summit.That is to say, as shown in Figure 3-4, the area from described summit to the described cross section along described rotary body plane of described feeding mouth 21 changes from small to big, thereby can reliably the material for the manufacture of catalyst be imported in rotary body equably.
Known by foregoing description, the utility model imports to the material for the manufacture of catalyst in rotary body 20 equably by flow-guiding structure is set on rotary body 20, because the guiding gutter being formed with on described flow-guiding structure arranges corresponding to described feeding mouth, and between adjacent described guiding gutter, formed fin converges at a bit.That is to say, described flow-guiding structure forms roughly back taper, and is provided with groove with respect to the position of described feeding mouth, with the direction of regulation material.; when described rotary body 20 is carried out to feeding; material can be directed in described feeding mouth equably; and there will not be the very concentrated situation of material; thereby make material in nozzle, be not easy to produce flow dead; solid phase particles can be because of deposition fouling, flocculation, thereby reduces widely the possibility of local caking.
Below describe by reference to the accompanying drawings preferred embodiment of the present utility model in detail; but; the utility model is not limited to the detail in above-mentioned embodiment; within the scope of technical conceive of the present utility model; can carry out multiple simple variant to the technical solution of the utility model, these simple variant all belong to protection domain of the present utility model.
It should be noted that in addition, each concrete technical characterictic described in the above-mentioned specific embodiment, in reconcilable situation, can combine by any suitable mode, for fear of unnecessary repetition, the utility model is to the explanation no longer separately of various possible combinations.
In addition, between various embodiment of the present utility model, also can be combined, as long as it is without prejudice to thought of the present utility model, it should be considered as content disclosed in the utility model equally.
