Abstract
The utility model provides a high-efficiency cyclone separator which has the advantages of small internal pressure drop and high separation efficiency. The high-efficiency cyclone separator comprises an upper cylinder and a barrel arranged in the inner cavity of the upper half part of the upper cylinder, wherein the barrel extends out of a cover plate which is arranged at the upper end of the upper cylinder, the barrel is hollow in the up-down direction, the upper part of the barrel is a fume outlet, the lower part of the barrel is an outlet of particles and a part of gas, and a fume inlet is formed at the upper end of the upper cylinder. The high-efficiency cyclone separator is characterized in that the lower end of the barrel is shaped into a taper of which the upper part is larger than the lower part, and a flow guide groove is formed on the inner wall of the lower end of the tapered barrel.
Description
Technical field
The utility model relates to and is used for petrochemical industry with desulfurizer use Cyclonic separating apparatus technical field, is specially efficient cyclone separator.
Background technology
In the oil refining apparatus, emission gases need reach environmental requirement, so need carry out desulfurization to discharge tail gas now; And in the desulfurizer, desulphurization catalyst normally through reducing/regenerating, recycle, and desulphurization catalyst is to collect through cyclone separator; Get back to then in the system, reuse.Existing cyclone separator; Its structure is seen Fig. 1, and it inner chamber that comprises the first half of upper shell 1, upper shell 1 is equipped with cylinder 2, and cylinder 2 passes from the upper end cover plate of upper shell 1; Cylinder 2 is a hollow up and down; Its top is the outlet 3 of flue gas, and the bottom is the outlet of particle and portion gas, and the upper end of upper shell 1 is provided with the import 4 of flue gas.The shortcoming of this separator is exactly: the void space between upper shell 1 and the cylinder 2 is big, enter so separator flue gas in rotation at a high speed down, the heavier particle in the flue gas under the gravity effect along the wall downslide of upper shell 1; Because void space is big, so comparatively speaking, the space in the cylinder is less; Cause the pressure drop in the space big like this, and pressure drop is big, the pressure of inner core top outlet is just very little; Even there is not pressure; The mobilization dynamic of air weakens significantly like this, causes separative efficiency to reduce significantly, and the particle in the flue gas can be discharged along with gas together; And the space of inner core is big, and reduce in the space between upper shell and the cylinder like this, and the space of inner core is big, and its internal drop is little, but the void space between upper shell and the cylinder is little, and pressure drop is big, causes the velocity of rotation of flue gas to reduce, and cyclonic separation efficient is low.
Summary of the invention
To the problems referred to above, the utility model provides a kind of efficient cyclone separator, and its internal pressure drops is little, and separative efficiency is high.
Its technical scheme is such: it inner chamber that comprises the first half of upper shell, said upper shell is equipped with cylinder; Said cylinder passes from the upper end cover plate of said upper shell; Described cylinder is a hollow up and down; Its top is the outlet of flue gas, and the bottom is the outlet of particle and portion gas, and the upper end of said upper shell is provided with the import of flue gas; It is characterized in that: big above the lower end of said cylinder is, below little cone shape, the inwall of the lower end of the cylinder of this cone shape is provided with guiding gutter.
It is further characterized in that: said guiding gutter is on the inwall that divergent shape is distributed in said cylinder lower end.
In the said structure of the utility model, cone shape is arranged in the lower end of inner core, and the mezzanine space between inner core and the upper shell strengthens like this; Like this, the pressure drop ratio in the interlayer is less, and the cone inwall is provided with guiding gutter; Offset the tapered lower portion space like this and reduced part, same, the pressure drop ratio of inner core inside is less; Like this, guaranteed the separating effect of whole cyclone separator.

Fig. 2 is the structural representation of the utility model.
The specific embodiment
See Fig. 2; The utility model comprises that the inner chamber of the first half of upper shell 1, upper shell 1 is equipped with cylinder 2, and cylinder 2 passes from the upper end cover plate of upper shell 1, and cylinder 2 is a hollow up and down; Its top is the outlet 3 of flue gas; The bottom is the outlet 4 of particle and portion gas, and the upper end of upper shell 1 is provided with the import 5 of flue gas, big above the lower end 6 of cylinder 2 is, below little cone shape; The inwall of the lower end of the cylinder of this cone shape 6 is provided with guiding gutter 7, and guiding gutter 7 is on the inwall of cylinder lower end that divergent shape is distributed in cone shape 6.
Claims (2)
1. efficient cyclone separator, it inner chamber that comprises the first half of upper shell, said upper shell is equipped with cylinder, and said cylinder passes from the upper end cover plate of said upper shell; Described cylinder is a hollow up and down; Its top is the outlet of flue gas, and the bottom is the outlet of particle and portion gas, and the upper end of said upper shell is provided with the import of flue gas; It is characterized in that: big above the lower end of said cylinder is, below little cone shape, the inwall of the lower end of the cylinder of this cone shape is provided with guiding gutter.
2. efficient cyclone separator according to claim 1 is characterized in that: said guiding gutter is on the inwall that divergent shape is distributed in said cylinder lower end.
