Description
Technical field
The present invention relates to purifier for treating water, specifically refer to the same flow oblique board sedimentation device in a kind of water supply draining.
Background technology
In water treatment field, rectangular sedimentation tank is the sedimentation used the earliest, but the floor space of this sedimentation basin is very large.And swash plate (pipe) sedimentation not only sedimentation effect is good, but also can make up the large shortcoming of flat flow sedimentation floor space, therefore the whole world is all widely with the flat flow sedimentation that this sedimentation replaces the earliest, and is applied in production practices.
Swash plate (pipe) sedimentation flows to divide to be divided into anisotropic flow (to upper reaches) from muddy water, vertical current (lateral flow), concurrent (to dirty), three kinds to flow in sedimentation that to count again the effect that concurrent swash plate (pipe) precipitates best, concurrent swash plate (pipe) precipitates because mudflow in precipitation process is identical with water (flow) direction, contribute to the downslide of mud like this, can not once flow velocity crosses conference cause muddy water disturbance as anisotropic flow swash plate (pipe) precipitation, therefore concurrent swash plate (pipe) precipitation can improve surface loading greatly, its surface loading precipitates high 3 ~ 5 times than anisotropic flow swash plate (pipe).In swash plate (pipe) group that concurrent swash plate (pipe) precipitates, water velocity is higher, can also overcome the deposition problem that anisotropic flow swash plate (pipe) precipitation group inside exists.In addition, because swash plate in same flow oblique board sedimentation (pipe) inclination angle is smaller, effective desilting area of its swash plate (pipe) is large, and sedimentation effect is good.Therefore, concurrent swash plate (pipe) sedimentation is a kind of High-rate sedimentation technology.
Write from memory under this University Engineering Department cooperates with Axel Heiberg Johnson industrial research institute Sweden Charlie in 1967, create " Lan Meila " separator (i.e. concurrent swash plate), and March next year to U.S. Patent.Within 1973, rise, China starts to have carried out the Test And Research Work of same flow oblique board sedimentation.But because this sedimentation exists following shortcoming, cause this efficient sedimentation to be difficult to use in production practices:
1, captation structure is very complicated, and same flow oblique board sedimentation device is identical with water (flow) direction due to mudflow in precipitation process, needs to arrange braiding channel collect clear water at precipitation end, and the clear water collected by return duct is discharged.The now captation of existing various shape, as blade type, overall drag type, trapezoidal etc., but structure is all very complicated, is not easy to construction assembling, and involves great expense.
2, due to need between two swash plates to arrange captation collect heavy after water, cause the spacing between two swash plates can not be too little, thus make desilting area be subject to certain limitation.But also increase by one section of slip plate at precipitation end, add cost and installation difficulty.
3, captation eyelet easily blocks, and captation aperture is all generally Φ 4 ~ Φ 10mm scope, and device local eyelet after running a period of time very easily blocks, and cisco unity malfunction, has a strong impact on the deposition efficiency of device.
4, same flow oblique board sedimentation basin body is joined and is catchmented uneven, and swash plate liquid level has the rectangular sedimentation tank body of spill along the overfall weir similar in appearance to one, and floccule body enters swash plate along journey, end is entered many, rear portion is entered few, causes end sludge concentration far away higher than rear portion, there will be deposition phenomenon on the swash plate of end.
Summary of the invention
For prior art above shortcomings, the present invention proposes a kind of same flow oblique board sedimentation device, adopt circular configuration, reach simple structure of catchmenting, be easy to collecting precipitation water outlet, be easy to mud-water separation, join the object even, space availability ratio height sedimentation effect is good of catchmenting, and reduce installation difficulty, reduce cost.
