Detailed description of the invention
Embodiment 1:
Fig. 1 is the hydrocone type separator assembly drawing of the embodiment of the present invention 1.Its hydrocone type separator 7 comprises a muddy water catch basin 9, tubule sedimentation unit 10, tank 11.Above-mentioned tubule sedimentation unit 10 is made up of thin sedimentation pipe 1, sleeve pipe 3, seal cover 4, sealing-plug 5, siphon outlet pipe 6, thin for most root sedimentation pipe 1 is made tube bank 2, tube bank 2 is closely inserted in sleeve pipe 3, with tapered lid 4, it is sealed on the top of this sleeve pipe 3; Have an aperture in the upper end of tapered lid 4, a sealing-plug 5 connecting siphon outlet pipe 6 closely clogs this aperture just.

The sedimentation principle of tubule sedimentation unit of the present invention is:
As shown in Figure 10 and Figure 11, following situation is considered: containing particle sinking speed W
0muddy water, with flow velocity U, for L, internal diameter are the sedimentation pipe of d, bottom flows into from long, and top is flowed out.As Figure 10 (a), if the inclination angle of sedimentation pipe is θ, with current at Bottomhole pressure, the rate of climb of suspension particles is
U-W
0·sinθ
In pipe, then flow into the time of staying T of outflow
1for
On the other hand, because the settling height in pipe is d/cos θ, therefore the sedimentation time T in pipe
2for
Work as T
1=T
2time, the disposal ability of this sedimentation pipe is maximum.At this moment lower relational expression can be able to
Can be obtained by (1)
Above (1) and (2-1), (2-2) is the basic formula of single tube sedimentation, because the diameter d of sedimentation pipe is very little compared with pipe range L; Even if so sinking speed W
0or the particle that particle diameter is less, due to L/d very large (as L/d=100), the suction velocity U of muddy water also can get higher value, thus realizes the high speed of micron particles sedimentation separation.
Might as well suppose sedimentation pipe range L=500mm, bore d=5mm, tiltangleθ=60 °, to be suspended in kaolin in water as particulate matter to be fractionated, its density is 2.65g/cm
3, the density of water is 1.0g/cm
3, water temperature is 20 DEG C, and the coefficient of dynamic viscosity of water is 10.1 × 10
-4n.s/m
2, acceleration of gravity gets 9.8m/s
2; So to ask the particle removed sinking speed and be greater than 0.022mm/s, by Stokes formula:
Wherein, d
1the particle diameter of-equivalent spheric granules, μm;
The coefficient of dynamic viscosity of μ-water, Ns/m
2;
W
0the sinking speed of-particle, mm/s;
The density of ρ-particle, g/cm
3;
ρ
0the density of-water, g/cm
3;
G-acceleration of gravity, gets 9.8m/s
2.
Can be calculated, the stokes particle diameter corresponding to this sinking speed is 5 microns, and now in pipe, water velocity can reach 1.129mm/s.Reynolds number computing formula by pipe stream:
Wherein, the Reynolds number of Re-pipe stream;
ρ
0the density of-water, gets 1.0 × 10
3kg/m
3;
Water velocity in U-pipe, m/s;
The internal diameter of d-sedimentation pipe, m.
Can be calculated, in tubule, Reynolds number is 5.59, therefore belongs to laminar flow domain, meets stokes formula application conditions.
The effect of concrete sedimentation unit, can with following example calculation as a reference.Suppose that section configuration is the square of length of side 5mm, long L=500mm, the sedimentation pipe of tiltangleθ=60 °, as Figure 10 (b); The sinking speed W of sedimentation separation
0the particle of=20m/d (83.3cm/h=1.389cm/min=0.0231cm/s), is had by formula (2-2)
Therefore the process flow of every this sedimentation pipe of root is
q＝1.18×0.5×0.5＝0.295cm
3/s
(＝17.7cm
3/min＝1.062L/h＝25.488L/d)
If by this sedimentation pipe 5 × 5=25 root, make sedimentation pipe unit, as Figure 10 (c), then the process flow of this module is
∑q＝25×0.295＝7.375cm
3/s(0.637m
3/d)
Namely the disposal ability of each module every day is as shown in the figure about 0.64m
3, in concrete enforcement, the module number of choice for use can be carried out according to the pending water yield; Further known cubic unit rice volume this kind of module daily handling ability is about 2038.4m
3.And for common upward flow sloping plate, inclined tube, if its spacing is 25mm, plate length or pipe range are 1000mm, under same separate and subside speed and angle of inclination, suppose that the supernatant that its sedimentation obtains all is discharged, the day process water yield of its cubic unit rice volume is also only 416.4m
3.
