Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model preferred embodiment is described further.
As depicted in figs. 1 and 2, a kind of butterfly settling vessel, it is installed in vertical sedimentation basin 100, comprises water inlet pipe 1 and the internal layer two-phase guide shell 2 of sealed bottom set gradually from the inside to the outside and the outer two-phase guide shell 3 of bottom-open; Bottom described outer two-phase guide shell 3, protection support lattice plate 4 is installed, is fixed on protection support lattice plate 4 bottom described internal layer two-phase guide shell 2; Described water inlet pipe 1 is communicated with internal layer two-phase guide shell 2 through outer two-phase guide shell 3, and upward, its shape is up big and down small bell mouth shape to the delivery port 11 of water inlet pipe; The bottom of described internal layer two-phase guide shell 2 is provided with discharge pipeline 5, and the outer two-phase guide shell 3 of described discharge pipeline 5 pass-out is outside; Be provided with liberation port 6 below described protection support lattice plate 4, described liberation port 6 shape is up-small and down-big bell mouth shape; Described liberation port 6 is communicated with sedimentation basin 100, is provided with reflecting plate 7 below liberation port 6, and described reflecting plate 7 is fixedly connected with by gripper shoe assembly 8 with liberation port 6.
The structure of the two-phase of internal layer described in the present embodiment guide shell 2, outer two-phase guide shell 3, waffle slab 4, reflecting plate 7 is conventional structure, and therefore not to repeat here.
In embodiment, liberation port also can be directly fixed on the support in sedimentation basin, but reflecting plate is directly fixedly connected with liberation port, complete equipment is dispatched from the factory just molded, can alleviate on-site installation work amount.
During work, current are carried through water inlet pipe 1, internal layer two-phase guide shell 2 is entered again by the horn-like delivery port 11 of antigravity, this process there occurs first time hydraulics change, be specially: current to be penetrated and under discharge section area becomes suddenly large acting in conjunction at antigravity rapids of gushing, make the loss of current longitudinal velocity head serious, macroscopically show as longitudinal initial velocity to diminish, longitudinal acceleration is the deceleration ascending motion of the horizontal turbulent fluctuation of slowing down, microcosmic shows as the horizontal rotary roll of particle, collision, the deceleration ascending motion of blending, flow energy is then converted into potential energy by kinetic energy and pressure energy.This just make the suspended particulate in water body can in internal layer two-phase guide shell 2 mutual Collision coagulation slabbing floccule body, larger floccule body then can be deposited in internal layer two-phase guide shell 2 in deceleration is risen, and discharge eventually through internal layer discharge pipeline 5, this is first time precipitation.
After this current overflow into outer two-phase guide shell 3 by internal layer two-phase guide shell 2 upper opening, this process there occurs the change of second time hydraulics, be specially: when current by internal layer two-phase guide shell 2 slow down rise to have a common boundary with outer two-phase guide shell 3 time, because gravity, upper strata hydraulic pressure and discharge section area become suddenly large acting in conjunction, longitudinal rate of climb of current reduces to zero substantially; Immediately, under the acting in conjunction of gravity and upper strata hydraulic pressure, current start to do the downward accelerated motion that initial velocity is zero in the vertical, horizontal then turbulent fluctuation before continuity, and flow energy is converted into kinetic energy and pressure energy by potential energy.This process not only makes current distribute on the cross-section of river more evenly effectively, also makes little micro-suspended particulate of failing to precipitate in internal layer two-phase guide shell 2 carry out mutual Collision coagulation further, too increases hydraulic detention time simultaneously.
Then current enter liberation port 6 by outer two-phase guide shell 3 through protection support lattice plate 4, now protection support lattice plate not only plays the effect supporting internal layer two-phase guide shell, further promote the homogenizing of current, then current impact on reflecting plate 7 by liberation port 6 again, last current inject the settling zone of vertical sedimentation basin by the peripheral effluent mouth rapids between liberation port 6 and reflecting plate 7, this process there occurs third time hydraulics change, be specially: when current accelerate to flow downward to protection support lattice plate 4 position by outer two-phase guide shell 3, because the unexpected change of cross-section of river section is large, make current thus rapids inject liberation port 6, in liberation port 6, the cross-section of river is become continuously large gradually, therefore current within it remain longitudinally accelerate to flow downward, the turbulence state of laterally fierce turbulent fluctuation, when current flow near reflecting plate 7, now current longitudinal velocity be increased to maximum, potential energy is converted into kinetic energy and pressure energy reaches maximum, particle momentum reaches maximum, so can the time of water impact reflecting plate 7 be considered as instantaneous, now particle momentum changes is maximum, cause current inverse change will occur in water velocity direction after shock-wave reflection plate 7, become from original acceleration the rapid settling zone injecting sedimentation basin effectively that rises evenly that slows down downwards.
Continue to do that longitudinal deceleration is risen, the turbulent motion of laterally fierce turbulent fluctuation after current rapids injects settling zone, make little micro-suspended particulate Collision coagulation mutually again.Little micro-suspended particulate, after the Collision coagulation under continuous three different hydraulics, substantially increases it forms sheet floccule body probability in settling zone, thus substantially increases it carries out stratification precipitation probability in settling zone.This is second time precipitation.
The design of butterfly settling vessel makes current experienced by three hydraulics changes and twice precipitation, the secondary hydraulics change of more vertical two-phase water conservancy diversion separator and primary sedimentation, under equal conditions, effectively extend sedimentation basin hydraulic detention time, suspended particulate Collision coagulation more thoroughly, improve that sedimentation basin hydraulic surface loading, sludge settling are more thorough, current water outlet SS and turbidity lower; Under equal conditions, can make that pond body specification reduces further, pond body construction investment is saved further, land seizure reduces further.
The vertical sedimentation basin internal structure being provided with butterfly settling vessel is simple, operation maintenance is convenient and simple, outlet effect is good, construction investment economizes.Designer can carry out reasonable selection according to the design water yield, water quality characteristics and process water Effluent criteria, thus goes out applicable vertical sedimentation basin according to its parameter designing; Combination design can also be carried out according to actual conditions and media filtration pond.Thus, the flexibility of the butterfly settling vessel as one of vertical sedimentation basin nucleus equipment, diversity, adaptability and actual effect has been fully demonstrated.
The foregoing is only the utility model preferred embodiment; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
