Description
Technical field
A kind of big tripe circular settling tank and its solid-liquid separating method, belong to solid-liquid separation technique field.
Background technology
At present, solid-liquid separation is the necessary process in water treatment procedure, and is early stage process, and the effect of solid-liquid separation is straight
Connect and have influence on later stage process.There are multiple sedimentation tanks in solid-liquid separation technique field, for example, vertical sedimentation tank, radial-flow sedimentation tank, advection
Sedimentation tank, mechanical accelerating purifying pool, potassium permanganate composites etc..Vertical sedimentation tank is suitable for the little occasion of the water yield, goes out aqueous suspension dense
Degree is of a relatively high, and radial-flow sedimentation tank and horizontal sedimentation tank are suitable for into aqueous suspension in certain limit, mechanical accelerating purifying pool and height
Density sedimentation tank complex structure, cost is high.Processing, the water yield is little, and water inlet concentration of suspension is high and changes repeatedly it is desirable to underflow is solid
Containing high occasion, lack a kind of means of effective solid-liquid separation.
Content of the invention
This utility model provides a kind of big tripe circular settling tank, and its energy effectively solving process water yield is little, enters aqueous suspension dense
Degree is high, the problem of solid-liquid separation effect difference, improves separating effect, it is high that underflow contains concentration admittedly.
The technical solution of the utility model is realized in
This utility model provides a kind of big tripe circular settling tank, is divided into upper area 1, upper transitional region from top to bottom
2nd, central region 3, lower transitional region 4, lower area 5；Central region 3 diameter is maximum, and upper area 1 diameter is slightly smaller, lower region
Domain 5 diameter is minimum；The upper end of upper area 1 is provided with annular collecting vat 7；It is upper transition region between upper area 1 and central region 3
Domain 2, connects in cone, pushes up one layer of horizontal stainless (steel) wire of each installation of going to the bottom, be provided between two layers of mesh in upper transitional region 2
Filler, mesh aperture is less than filler external diameter；It is connected in inverted cone between central region 3 and lower area 5；From upper area 1
Center extends downward central region 3 center You Yige center water inlet pipe 6；From the bottom of lower area 5 be connected with discharge pipeline 8,
Return mud pipe 9；Return mud pipe 9 to be connected with center water inlet pipe 6 by circulating pump 10, circulating line 11.
Above-mentioned big tripe circular settling tank is it is characterised in that sedimentation tank total height is between 5m-14m；Central region 3 straight
Footpath is 1: 0.7-0.9 with the diameter ratio of upper area 1；The diameter of central region 3 is 1 with the diameter ratio of lower area 5:
0.4-0.6.
The application also provides a kind of solid-liquid separating method, and it utilizes above-mentioned big tripe circular settling tank separation solidliquid mixture,
First solidliquid mixture is entered central region 3 by center water inlet pipe 6, open the circulation pump 10 simultaneously, by lower area 5
Partly precipitated thing enters center water inlet pipe 6 by returning mud pipe 9, circulating pump 10 and circulating line 11, mixes with the new solid-liquid entering
Compound mixes, and big tripe circular settling tank is full of solidliquid mixture, in diameter maximum central region 3, coagulation, shape occurs
Become flco, solid-liquid initial gross separation completed by the effect of gravity, current rise, by upper transitional region 2, then collide with filler,
Tiny flco is intercepted further, forms clear water in upper area 1, by annular collecting vat 7 row of upper area 1 upper end
Go out, lower area 5 forms precipitate, is discharged by discharge pipeline 8.
According to above-mentioned solid-liquid separating method it is characterised in that sedimentation tank total height is between 5m-14m；Central region 3
The diameter ratio of diameter and upper area 1 be 1: 0.7-0.9；The diameter of central region 3 and the diameter ratio of lower area 5
For 1: 0.4-0.6.
If solidliquid mixture is mud slurry, upper area is clear water zone, and zone line is body refuse flocculation zone, bottom
Region is body refuse enrichment region；The body refuse circulating pump of lower area bottom is recycled to center water inlet pipe, and the dirt entering central canal
After material-mud mixing, central region is entered by center water inlet pipe, after central region completes coagulation, clear water mud, slag wadding upwards
Solidifying body sinks, and completes solid-liquid separation.
In central region, due to sludge circulation be increased by circulating pump, mix float in later mud slurry dense
Degree is high, and between mud granule, collision probability is big, quickly completes initial stage coagulation, flocculation process, and the batting-unit structure due to being formed is close
Real, ratio is great, easily precipitates, and enters the lower transitional region of cone, occur further in lower transitional region after separating with water
Crowded precipitation, flocculation bulk concentration improves further, finally enters lower area：Body refuse enrichment region, in body refuse enrichment region, floccule body
Concentration improves constantly, and floccule body is agglomerating, and proportion is bigger, compresses further, becomes body refuse, opens mud valve and discharges from discharge pipeline.
In central region, some tiny floccule body not flocculated, rise such as current, in upper transitional region
Push up one layer of horizontal stainless (steel) wire of each installation of going to the bottom, filler is installed between two layers of mesh, mesh aperture is less than filler external diameter, is equivalent to
Increase mud granule concentration in mud slurry, increase the collision probability of floccule body and filler, filler is equivalent to filter medium simultaneously,
Also there is adsorption on filler surface to floccule body, can effectively intercept tiny floccule body, purify water further.By adjusting filler
Highly (thickness), form of bio-carrier, the flow of adjustment sludge circulation pump, it is adapted to the change of water quality treatment it is ensured that separating effect.
On filler, the sludge solid of attachment is come off by downward current scour during lower area spoil disposal, enters middle region
Domain：Sludge suspension layer；Finally, the clear water after separating is concentrated by the annular collecting vat of upper area upper end and is discharged.
This utility model, according to the requirement processing the water yield, Inlet and outlet water concentration of suspension, bottom sediment, can design each
Plant parameter：The diameter (clear water zone diameter) of ￠ 1- upper area 1, the diameter (sludge suspension layer) of ￠ 2- central region 3, under ￠ 3-
The diameter (body refuse enrichment region) in portion region 5, the height (body refuse enrichment region) of H5- lower area 5, the height of transitional region 4 under H4-
(body refuse transition region), the height (sludge suspension layer) of H3- central region 3, the height (separating transition region) of the upper transitional region of H2- 2,
The height (clear water zone) of H1- upper area 1.Typically above-mentioned ginseng is determined by MaterialBalance Computation, structure design and model test
Number.
By above-mentioned big this design concept of tripe circular settling tank, the effect reaching is that the effectively solving process water yield is little, outstanding
Float concentration is high, the problem of solid-liquid separation effect difference, improves separating effect, it is high that underflow contains concentration admittedly.
