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 that uses 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, so the whole world all replaces the earliest flat flow sedimentation with this sedimentation widely, and it applied in production practices.
swash plate (pipe) sedimentation flows to divide to be divided into anisotropic flow (to the upper reaches) from muddy water, vertical current (lateral flow), concurrent (to dirty), three kinds flow in sedimentation that to count again the effect that concurrent swash plates (pipe) precipitate best, concurrent swash plate (pipe) precipitation is because mudflow in precipitation process is identical with water (flow) direction, help like this downslide of mud, can be as anisotropic flow swash plate (pipe) in case precipitation, flow velocity is crossed conference and is caused the muddy water disturbance, therefore concurrent swash plate (pipe) precipitation can improve surface loading greatly, its surface loading is higher 3～5 times than anisotropic flow swash plate (pipe) precipitation.In swash plate (pipe) group of concurrent swash plate (pipe) precipitation, water velocity is higher, can also overcome the inner deposition problem that exists of anisotropic flow swash plate (pipe) precipitation group.In addition, smaller due to swash plate in same flow oblique board sedimentation (pipe) inclination angle, 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.
Under silent this University Engineering of Sweden Charlie in 1967 institute and Axel Heiberg Johnson industrial research institute cooperate, created " Lan Meila " separator (being the concurrent swash plate), and March next year to the U. S. application patent.Rose in 1973, China begins to have carried out the Test And Research Work of same flow oblique board sedimentation.But because there is following shortcoming in this sedimentation, cause this efficient sedimentation to be difficult to use in production practices:
1, the captation structure is very complicated, and the same flow oblique board sedimentation device need to arrange braiding channel at the precipitation end and collect clear water, and discharge collected clear water by return duct because mudflow in precipitation process is identical with water (flow) direction.The existing captation of existing various shapes, as cutter type, overall drag type, trapezoidal etc., but structure is all very complicated, is not easy to the construction assembling, and involves great expense.
2, due to need to arrange between two swash plates captation collect heavy after water, cause the spacing between two swash plates can not be too little, thereby make desilting area be subject to certain limitation.But also increase by one section slip plate at the precipitation end, increased cost and installation difficulty.
3, the captation eyelet easily stops up, and the captation aperture is all generally Φ 4～Φ 10mm scope, device through operation a period of time after local eyelet very easily stop up, cisco unity malfunction has a strong impact on the deposition efficiency of device.
4, the same flow oblique board sedimentation basin body is joined and is catchmented inhomogeneously, and the swash plate liquid level is similar in appearance to a rectangular sedimentation tank body that spill along the overfall weir is arranged, and floccule body enters swash plate along journey, the end is advanced manyly, the rear portion is advanced less, causes the end sludge concentration far away higher than the rear portion, deposition phenomenon on the swash plate of end can occur.
Summary of the invention
For the prior art above shortcomings, the present invention proposes a kind of same flow oblique board sedimentation device, adopt circular configuration, reach the simple structure of catchmenting, be easy to the collecting precipitation water outlet, be easy to mud-water separation, join catchment even, the good purpose of the high sedimentation effect of space availability ratio, and the reduction installation difficulty, reduce cost.
