Description
Technical field
The present invention relates to a kind of water distribution guiding device for water treatment deposition technique.This device is mainly used in, in water treatment tube settler water distributing area, effectively to reduce water distributing area fluidised form Froude number, weakens on the bed mud that causes because water distribution is uneven and turns over phenomenon, improve effluent quality.
Background technology
Tube settler is one of modal process structures in water treatment technology, can significantly improve deposition efficiency, save floor occupying area.A lot of water treatment building, such as potassium permanganate composites etc. are all take tube settler as the novel sedimentation basin that prototype development gets up.Desirable tube settler deposition efficiency should determine primarily of the heavy speed of particle and upflow velocity.But tube settler mud-water separation district is connected with water inlet, be easy to the impact being subject to lateral intake flow velocity.When side direction flow velocity is very little, make fluidised form be in laminar condition, then less on the flco impact of free settling.But when side direction flow velocity causes subregion flow velocity excessive due to the impact of non-uniform flow, then can improve the Reynolds number of this regional fluid, produce local turbulent.Turbulent flow can affect the flco of free settling, even destroy and flutter volume due to net and sweep group's sedimentation flco that phenomenon causes, thus cause should the little flco of sedimentation but along with ascending current floats, affect mud-water separation effect, cause on settling zone bed mud and turn over, reduce deposition efficiency and effluent quality.When flow of inlet water is close to design discharge, more easily there is this situation, thus affect the efficiency of actual of tube settler.Therefore, when flow of inlet water is certain, should ensures that fluidised form is even as far as possible, reduce the flow velocity variance of the same section of water inlet.But due to the impact of the factors such as speed difference, the temperature difference and density contrast, be difficult to during actual motion accomplish that fluidised form is even.This uneven fluidised form is the one of the main reasons causing tube settler fluctuation of service.
For head it off, prior art pays close attention to the oblique barricade of water distributing area end usually on the impact of water distribution uniformity, by changing angle, the length even flexibility of oblique barricade, analyzes water distribution uniformity.But prior art have ignored front end, water distributing area due to the higher disorderly phenomenon caused of water inlet Froude number.Find that the design of front end, water distributing area serves vital effect for water distribution uniformity by analogue simulation, but the simple water distributing area design optimization that relies on exists bottleneck, water distribution uniformity is more difficult continuation lifting after reaching a certain extreme value.The difficult point of further lifting water distribution uniformity is for the flow condition such as different flow, water temperature, adjusts accordingly.Fixing water distributing area is difficult to realize adjusting different condition, and this is also the still unsolved key problem in technology point of existing pipe chute deposition technique.
In addition, the process of tube settler water distribution is also a part for flocculation.Current tube settler in order to save floor occupying area, the usually mechanical flocculation basin of collocation.The machinery flocculation basin inner G value difference opposite sex is very large, is much easily stirred oar compared with big flocculating body and is broken into little flco.Again can assemble after these little flcos enter tube settler water distributing area, thus complete mud-water separation in settling zone.Therefore the design of tube settler water distributing area is except considering water distribution uniformity, also should consider the effect of flocculation.Traditional tube settler water distributing area does not possess special flocculation region substantially, is unfavorable for the gathering again of broken flco.One of reason causing this factor is that the inclined tube of tube settler takies a large amount of area, and water distributing area takes into account the function in overhaul of the equipments hole usually, and this region cannot be utilized to arrange flocculation measure.How giving full play to the flocculation performance of water distributing area, and do not affect tube settler general function, is that pipe chute deposition technique further develops faced new problem.
Summary of the invention
The object of the invention is to provide a kind of water distribution fairing for tube settler or its derivative structures, promote tube settler water distribution uniformity, strengthen flco and re-unite effect, promote heavy effect and effluent quality, do not affect tube settler general function simultaneously, be applicable to the newly-built or transformation project of various use pipe chute deposition technique.
To achieve these goals, technical scheme of the present invention is: a kind of tube settler water distribution guiding device, tube settler water distributing area end is provided with oblique barricade, the angle of described oblique barricade and horizontal plane is α, it is characterized in that: described guiding device comprises deflector, described deflector is divided into upper and lower two parts, and the first half is vertical baffle, the latter half is inclination deflector, and the angle of inclination deflector and horizontal plane is between α is to 90 °.Described guiding device arranges some pieces of deflectors, and described some pieces of deflectors are fixed in tube settler by retractor device, and the oblique barricade distance of distance water distributing area end is far away, then the latter half angle of inclination of deflector is larger.Described retractor device comprises the glide base be fixed in tube settler, slide block is provided with in glide base, described deflector is connected with slide block by expansion link, and described slide block is also received bar with one and is connected, and described storage bar vertically slides under storage gear-box controls.Deflector side arranges flusher, adopts side direction flushing water to rinse deflector.Described vertical baffle also arranges some diversion window.
Guiding device of the present invention can realize, to the adjustment of water distribution uniformity, strengthening flocculating effect simultaneously.Retractor device can realize storage function when overhauling, and does not affect tube settler maintenance.Flusher is convenient to the maintenance of device day-to-day operation.The magnitude setting of deflector of the present invention and angle is set should arranges according to sedimentation basin water distributing area size, its major function is under the condition ensureing normal flocculation, at utmost reduce the non-uniform phenomenon that the factor such as density current, turbulent flow causes, make full use of water distributing area dischargeable capacity and carry out flocculation, strengthen flocculating effect.By cutting down non-uniform flow phenomenon, can effectively reduce the Peak Flow Rate entering settling zone, thus realize the smooth transition of flocculation to precipitation, reduce the perturbation action of settling zone water inlet to suspension body refuse.Water distribution guiding device of the present invention can be arranged on both sides, water distributing area pool wall according to concrete pond type, strong adaptability, both can be used for newly-built pond type, can be used for again transformation pond type.
