Description
Technical field
The present invention relates to a kind of bilayer for water treatment flocculation process incorgruous circulation machinery flocculation enhancing device.
Background technology
The optimization of water treatment flocculation process is generally for flocculating in the same way.Flocculate in the same way and mainly refer to that the flco caused by external force is assembled or fragmentation, this external force is called as G value, i.e. velocity slope.China's present stage, when carrying out the design of flocculation structures, uses the parameter such as flocculation zone head loss or mechanical output (G value) to design usually.But this G value is mean value, have ignored the otherness distribution of G value in flocculation region, it is particularly outstanding that this problem shows in mechanical flocculation basin.
Machinery flocculation basin drives stirring rake by drive unit and makes aqueous agitation to complete the structures of flocculation process.Machinery flocculation process floor space is little, and water quality and water yield strong adaptability, be used widely at water treatment field.Machinery flocculation basin generally adopts pulling flow type blade, selects individual layer or multi-layer oar blade according to the dark feature in pond.But the inner G Distribution value of mechanical flocculation basin is uneven, very easily there is the unfavorable phenomenons such as the broken or G value flco cohesion on the low side difference of the too high flco of G value.Meanwhile, in pond, fluidised form is difficult to control, and short flow phenomenon very easily occurs, and reduces effluent quality.
Traditional enhanced flocculation device increases guiding device, makes flocculation basin internal flow state stable circulation, increases flco collision efficiency.But owing to lacking the research to flocculation basin inside G Distribution value rule, machinery flocculation guiding device is generally only a straight guide shell, the short flow phenomenon that machinery flocculation exists to there is the excessive flco that causes of G value in guide shell broken, these are unfavorable for that the factor of flocculation is better solved always.The mechanical flocculation plant of current most manufacturers produce still lacks the heightened awareness to mechanical flocculating principles, fails to design with mechanical flocculation process structures to combine preferably.Therefore, the prerequisite of machinery flocculation enhancing device research and development is multianalysis flocculation basin inside flocculation reaction process, and for flocculation basin internal features, research and development can promote the mechanical flocculation plant of flocculating effect.
Summary of the invention
The present invention is to solve the flocculation plant machinery flocculation efficiency of prior art is lower, easily there is short flow phenomenon, the problem of effluent quality difference, provide a kind of double-deck incorgruous circulation machinery flocculation enhancing device.
The present invention solves the problems of the technologies described above mainly through following technical scheme:
A kind of double-deck incorgruous circulation machinery flocculation enhancing device, it comprises motor reducer, shaft coupling, drive shaft, stirring rake, guide shell and fixed support, described stirring rake comprises upper strata stirring rake and lower floor's stirring rake, described upper strata stirring rake and described lower floor stirring rake is incorgruous is installed on described drive shaft; The barrel of described guide shell is a curved surface, and described guide shell comprises upper strata guide shell and lower floor's guide shell, and guide shell correspondence in described upper strata is installed on the outside of described upper strata stirring rake, and described lower floor guide shell correspondence is installed on the outside of described lower floor stirring rake.
Preferably, the blade of described stirring rake is three pulling flow type blades.Pulling flow type stirring rake principal feature promotes current to be moved by upstream toward downstream direction.Because mechanical flocculation reaction high efficiency range is mainly positioned at stirring rake and downstream certain limit thereof.In view of the faster high efficiency range of mixing speed is wider, but flco also more breakable rule, this device adopts double-deck incorgruous stirring rake.By the incorgruous stirring of bilayer, stirring rake downstream high efficiency range can be increased when lower mixing speed, thus increase flocculation structures flocculation efficiency.Coordinate double-deck guiding device, can strengthen double-deck incorgruous agitation cycle efficiency, bilayer is circulating fluidized simultaneously in the inner upper and lower two portions flocculation zone of self-assembling formation of flocculation structures, can form barrier layer, reduces the generation of the short flow phenomenon of structures that flocculates.
Preferably, the blade width of described stirring rake is 200-1000mm, and the blade length of described stirring rake is 400-2000mm, and the blade impeller pitch angle of described stirring rake is 15-35 °.By changing the blade ratio of levels stirring rake, can form the bilayer circulation that flocculating strength is different, G Distribution value is more conducive to flocculation reaction.
Preferably, the plug-flow direction of described upper strata stirring rake upwards.When drive unit rotates forward, upper strata stirring rake promotes on current direction, and water circulates downwards after flowing to free surface thereupon, and under lower floor's stirring rake promotes current direction, current drive base sludge to cocycle, form negative pressure-pumping effect between Double-layer stirring paddle.
Preferably, the import and export of described guide shell all adopt closing in type.Wherein import is conducive to reducing stirring rake and rotates the broken region of height turbulent flow flco of bringing, and outlet is conducive to reducing downstream central low turbulent region scope, and expansion is effectively flocculated region.Curved design causes sectional area change inside and outside guide shell, have also been enlarged the inside and outside effectively flocculation zone volume of guide shell.
Preferably, described guide shell adopts permanent magnet material to make.Guide shell uses permanent magnet material, outer can form magnetic field within it, inner ion can be made after making hydro jet magnetic line of force to obtain magnetic energy and magnetic flocculation effect occurs, reduce the viscosity of water, be conducive to improving flocculation rate and subsequent filter effect, and the specific pollutants such as heavy metal ion have obvious clearance.
Preferably, the radius of described guide shell is 500-2500mm, the height of described guide shell is 1000-2000mm, and the vertical spacing between described upper strata guide shell and described lower floor guide shell is 300-1500mm, and the cylinder outer rim of described guide shell and horizontal plane angle are 45-60 °.Double-deck guide shell and Double-layer stirring paddle supporting, fluidised form feature specific design inside and outside guide shell when relative position and curved design are run according to stirring rake.
Preferably, the top of described guide shell is 500-2000mm to liquid level distance, and at the bottom of bottom to the pond of described guide shell, distance is 500-2000mm.Double-deck flocculation region, except by changing levels stirring rake and guide shell size, also can be incorporated into the final conditions such as water outlet direction, forms strong and weak two-stage flocculation region.Strong flocculation zone is near water-in, and weak flocculation zone, near water outlet, makes to form strong and weak two-stage flocculating effect in same flocculation basin, improves the service efficiency in space, also advantageously in the cohesion of flco.
Preferably, described drive shaft, fixed support all adopt stainless steel to make.Fixed support is fixedly connected with at the bottom of pond, the steady running of assurance device.
On the basis meeting this area general knowledge, above-mentioned each optimum condition, can arbitrary combination, obtains the preferred embodiments of the invention.
Positive progressive effect of the present invention is: the present invention adopts double-deck incorgruous pulling flow type stirring rake, in conjunction with double-deck curved surface guide shell, form the incorgruous circulation of Dual-layer, make full use of flocculation structures useful volume, improve mechanical flocculation process effciency of energy transfer, energy efficient, improves flocculating effect simultaneously, reduce short flow phenomenon, improve effluent quality.
