It introduces.
Stream containing fog, axially into air inlet 8, enters cylinder fibre by the air inlet opened up on the second fixed disk 1-2 from pipeline
It ties up in grid frame 1, under the resistance shunting function for pressing deflection cone 2, stream containing fog is by axially varying for radially vertically into coaxial
First group in several fiber grid groups 3.Air velocity containing mist is larger at this time, while the fiber in first group of fiber grid group 2 is straight
Diameter is larger, and the drop in stream containing fog mainly traps removal by the fiber in fiber grid in the mechanism of collision, interception, string vibration, attached
Become liquid film under gravity in the drop of fiber, be finally pooled to catch basin 5.
When the continuation of stream containing fog is radially flowed, several fiber grid groups 3 are co-axially located in cylinder fiber grid frame 1,
The arranging density of several fiber grid groups 3 successively increases along the center of cylinder fiber grid frame 1 to the edge of cylinder fiber grid frame 3

Dry fibers grid group 3.And the aperture of the fiber holes of several first fiber holes groups and several second fiber holes groups is by the first fixed disk 1-1
The center of circle successively reduced to the periphery of the first fixed disk 1-1.So flow section increases with radius and is increased, foundation
Fluid mechanics principle, flow velocity reduce, and when stream containing fog reaches second group of fiber grid group, the drop in air-flow is then by intercepting, touching
It hits and spreads collective effect and trapped and removed by the fiber in second group of fiber grid group, the drop being captured is equally in the work of gravity
Catch basin 5 is pooled under.Continue with flowing, flow velocity is also smaller and smaller, and fiber alignment density also increases, in subsequent fiber grid
In group, drop is then mainly trapped by the fiber in fiber grid group in the effect of diffusion and is removed.The drop trapped by fiber is same
Catch basin 5 is pooled in gravity.Since flow velocity is square increase with radius and reduce, so, when stream containing fog
To when reaching outermost fibers grid group, speed is minimum, Chord vibration is eliminated, without water from it ensure that out stream in terms of two.Most
The liquid of catch basin 5 can be emptied periodically by drain valve 6 afterwards, can also be emptied according to the liquid level of setting by drain valve 6.
Meanwhile first fiber holes group and the second fiber holes group uniformly set around the center of circle of the first positioning disk 1-1 is equiangularly spaced
It sets, circumferentially shape coaxial multi-layer is arranged in cylinder fiber grid frame 1 several fiber grid groups, and fiber grid is by several fibrous layer structures
At the spacing between several fibrous layers is 1.2 times of fibre diameter.Three adjacent fibers in any two adjacent fibrous layers are formed
Isosceles triangle arrangement, purpose increase the touch opportunity of liquid and fiber in stream containing fog, meanwhile, reduce resistance, it is therefore an objective to
Increase the touch opportunity of the liquid and fiber in stream containing fog, meanwhile, reduce resistance.
The application constitutes coaxial fiber grid group by several fibers along the setting of different circumference, and stream containing fog is directed radially through
Coaxial several fiber grid groups increase with radius in radial direction according to fluid mechanics principle air-flow and are reduced, realize speed change demisting,
And going out stream fiber grid outermost layer, speed is minimum, reduces out stream band water.In structure, the fiber grid group of several circumference is grouped,
The diameter reduction of fiber and changing for the fiber interlamellar spacing in every group of fiber grid group of fiber grid group in different groups from inside to outside
Become, the collision, interception, string for removing big drop for realizing every group of main demisting mechanism from interior group are shaken to the diffusion for removing droplet
Variation, realize multistage demisting in the variation of this clock demisting mechanism.The application can determine unsteady flow speed circle according to use occasion
The size of the diameter of all fiber grids, changes simultaneously the number of plies；It can be mounted directly on pipeline, reduce occupied area, demisting device junction
Structure is simple, processing and fabricating is convenient, demisting efficiency is high, has very strong practicability.
Only one component of the application is constituted, simple and compact for structure, easy to process；Stream containing fog is from axially into circumference fibre
It realizes under the action of deflection cone after dimension grid group and presses, make stream containing fog perpendicular through fiber grid group；Fibre is flowed through in entire air-flow
During tieing up grid group, by the variation of the diameter and arranging density of fiber grid group, the change of purification mechanism is formed, and then formed more
Grade purification, improves efficiency；It can be transversely mounted also longitudinally mounted, also can be directly mounted on pipeline, it is practical.
It should be noted last that the above specific embodiment is only to illustrate the technical solution of the utility model rather than limits
System, although the utility model is described in detail referring to example, those skilled in the art should understand that, it can be right
