Abstract
The utility model relates to a high efficiency whirlwind type gas-solid separator, the inner wall surface of the separator rough aerodynamics, the rough inner wall surface enhances the turbulent intensity near to the wall surface, increases the collision opportunities among the solid phase particles and the collision opportunities between the solid phase particles and the wall surface, and thereby, improves the separation efficiency of the separator. The high efficiency whirlwind type gas-solid separator can be useful for the reclamation and dust removal of the solid phase particles.
Description
The gas-solid separator of a kind of cyclone type efficiently.
The gas-solid separator of cyclone type is to utilize gas-solid phase particles mixed airflow to enter from axial symmetry cylinder upper tangential, and rotatablely moving of formation under centrifugal action, got rid of solid phase particles to wall, falls with the wall collision; Gas is then borrowed the effect of interior vortex, by upwards discharging in the axial symmetry cylinder, reaches the purpose of gas-solid separation.
At present, the gas-solid separator kind of cyclone type that is used for the recovery of dedusting and solid phase particles is a lot, as CLT type, D type, Type B, bypass type, diffusion type, long cone, multitube, cyclone cyclone separator, twin-stage spiral separator etc.But the gas-solid separator of all so far cyclone types has a common feature, be exactly inner wall surface thereof all be the aerodynamics shiny surface.
We know from hydrodynamics knowledge, flow through the high velocity air of aerodynamics shiny surface.In zone near wall.Exist a laminar flow sublayer.In this layer, turbulence intensity is very weak, and viscosity plays a leading role.It is relative seldom with the chance of wall collision to be thrown near the solid phase particles of wall.Therefore, in general, the gas-solid separator separative efficiency of the cyclone type of aerodynamics shiny surface inwall is relatively very low.
The performance quality of the gas-solid separator of cyclone type has two important index: the one, and separative efficiency; The 2nd, the size of the pressure loss.Under the condition that does not increase the pressure loss, improve separative efficiency, the air dynamic behaviour of internal face that can be by changing separator reaches.
The purpose of this utility model is to provide a kind of cyclone type efficiently gas-solid separator, its inwall is made the aerodynamics matsurface, thereby changed near the air dynamic behaviour the separator internal face, made this separator under the condition that does not increase the pressure loss, improved separative efficiency.
Fig. 1 is principle of the present utility model and implements illustration.
Fig. 2 is an axial symmetry inboard wall of cylinder face diagrammatic sketch.
Fig. 3 is an axial symmetry inboard wall of cylinder face diagrammatic sketch.
Fig. 4 is an axial symmetry inboard wall of cylinder face diagrammatic sketch.
Fig. 5 is an axial symmetry inboard wall of cylinder face diagrammatic sketch.
The utility model is made up of tangential inlet shown in Figure 1 (1), axial symmetry cylinder (2), aerodynamics internal face (3), solid phase particles outlet (4) and gas vent (5).After gas-solid phase particles mixed airflow entered axial symmetry cylinder (2) by tangential inlet (1), generation rotatablely moved.During the gas-solid mixed airflow process coarse internal face of aerodynamics (3), turbulent flow shear stress increases near the wall, and turbulence intensity increases, and has aggravated to reach between the solid phase particles collision of solid phase particles and wall.Thereby improved separative efficiency.The solid phase particles that collision is fallen is discharged by solid phase particles outlet (4); Gas is then upwards discharged from gas vent (5) by axial symmetry cylinder center.
In the utility model, the roughness element height Z of the coarse inwall of aerodynamics
0Should satisfy Z
0〉=C (v)/(u
*) (V is a kinematic viscosity coefficient in the formula, u
*Be friction velocity, C ≈ 70 is a constant) so that roughness element exceeds laminar flow sublayer thickness.
Embodiment: the gas-solid separator of cyclone type as shown in Figure 1, inner wall surface thereof roughness element can be made as Fig. 2, Fig. 3, Fig. 4, shape shown in Figure 5, also can make other aerodynamics matsurface shape.After gas-solid phase particles mixed airflow entered axial symmetry cylinder (2) by separator tangential inlet (1), formation rotatablely moved.Because inwall is that aerodynamics is coarse, when gas-solid mixed airflow through out-of-date, near the turbulent flow shear stress the wall increases, turbulence intensity increases, the collision opportunity that reaches solid phase particles and wall between the solid phase particles increases, and the deposition of solid phase particles increases, and separative efficiency obviously improves.Solid phase particles and gas are discharged by solid phase particles outlet (4) and gas vent (5) respectively.
The utility model is applicable to the gas-solid separator of the cyclone type of any type. Existing cyclone separator is reequiped also very convenient.
