The specific embodiment
Embodiment 1:
Fig. 1 is the hydrocone type separator assembly drawing of the embodiment of the 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, the thin sedimentation pipe 1 of most roots is made tube bank 2, to restrain 2 and closely insert in the sleeve pipe 3, on the top of this sleeve pipe 3 with tapered lid 4 to its sealing; Have an aperture in the upper end of tapered lid 4, a sealing-plug 5 that connects 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, consider following situation: contain particle sinking speed W
0Muddy water, with flow velocity U, from long be that the bottom of the sedimentation pipe of d flows into for L, internal diameter, flow out on top.As Figure 10 (a), the inclination angle of establishing sedimentation pipe is θ, follows current to flow in pipe, and the rate of climb of outstanding turbid particle is
U-W
0·sinθ
Then flow into the time of staying T of outflow in manage
1For
On the other hand, because the settling height in the pipe is d/cos θ, so the sedimentation time T in the pipe
2For
Work as T
1=T
2The time, the disposal ability of this sedimentation pipe is maximum.At this moment can be descended relational expression
Can obtain by (1)
Above (1) with (2-1), (2-2) be the basic formula of single tube sedimentation, because the diameter d of sedimentation pipe is compared very little with pipe range L; Even so sinking speed W
0Or the particle diameter smaller particles, because L/d very big (as L/d=100), the suction velocity U of muddy water also can get higher value, thereby realizes the high speed of micron particles sedimentation separation.
Might as well suppose sedimentation pipe range L=500mm, bore d=5mm, tiltangle=60 °, to be suspended in kaolin in the 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 ℃, the coefficient of dynamic viscosity of water is 10.1 * 10
-4Ns/m
2, acceleration of gravity is got 9.8m/s
2So if require to remove the particle of sinking speed, by the Stokes formula greater than 0.022mm/s:
Wherein, d
1-equivalent spherical particle grain size, μ m;
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 is got 9.8m/s
2
Calculating can get, and is 5 microns corresponding to the stokes particle diameter of this sinking speed, and water velocity can reach 1.129mm/s in this moment pipe.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 the U-pipe, m/s;
The internal diameter of d-sedimentation pipe, m.
Calculating can get, and Reynolds number is 5.59 in the tubule, so belong to the laminar flow scope, satisfies stokes formula application conditions.

0The particle of=20m/d (83.3cm/h=1.389cm/min=0.0231cm/s), (2-2) has by formula
Therefore the processing flow of every this sedimentation pipe is
q＝1.18×0.5×0.5＝0.295cm
3/s
(＝17.7cm
3/min＝1.062L/h＝25.488L/d)
If with this sedimentation pipe 5 * 5=25 root, make the sedimentation pipe unit, as Figure 10 (c), then the processing flow of this module is
∑q＝25×0.295＝7.375cm
3/s(0.637m
3/d)
The disposal ability that is each module every day as shown in the figure is about 0.64m
3, in concrete the enforcement, can select the module number that uses according to the pending water yield; Further this kind of unit cubic meter volume module daily handling ability is about 2038.4m as can be known
3And for common upward flow swash 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 is all discharged, it also only is 416.4m that the day of its unit cubic meter volume is handled the water yield
3
