Abstract

The invention provides a rotary barrel type sewage precipitator with an inclined plate, which can be used for accelerating a precipitation process in sewage treatment, clarifying a water body and improving the sewage treatment effect. According to the rotary barrel type sewage precipitator, a movable barrel which is internally provided with overlapped and arrayed parallel arc-shaped plate sets is eccentrically and fixedly arranged on a rotary shaft; a plurality of shallow-layer precipitation tanks with great length are formed by gaps between the adjacent arc-shaped plates; the water body to be treated and deposited sediments move mutually stably and are separated in a precipitation shallow layer. When the rotary shaft rotates, the radius vectors from a rotary center to all tank walls are different and an eccentric barrel wall carries out displacement in the radial direction (the radial distance from the barrel wall to the rotary center is lengthened or shortened); the shape of the barrel wall enforces fluid to centrifugally or concentrically flow to form continuous fluid layer flow movement; retardation balance is damaged continuously and floc cores are contacted, collided, adhered and polymerized mutually to form dense floc which separated from water; raw mater is clarified and purified. The rotary barrel type sewage precipitator is rotated around the rotary shaft, and shearing flow is formed on the tank walls and has a flushing effect on sludge; the possible sludge and blocks can be cleaned very conveniently.

Description

Drum-type settlement of sewage device with swash plate
Technical field
The present invention relates to a kind of precipitation process that can accelerate in sewage disposal, clarification water body, the drum-type settlement of sewage device with swash plate of raising wastewater treatment efficiency.
Background technology
In recent years, China's rapid economic development, urban wastewater discharge continues to increase, and Urban Water Environment is subject to severe contamination, and effluent problem has been severe environmental protection of China and economic problems.Because cost of sewage disposal is high, finance drops into hard to carry on, makes wastewater treatment in China rate very low, and the cost of sewage disposal and treatment effeciency have greatly restricted the development of sewage disposal industry.Therefore, research and development cost is low, and the sewage treatment technique that speed is fast, efficiency is high, new equipment are the developing direction of sewage disposal industry.
Sedimentation basin is the processing structures that utilize gravitational settling effect that the large suspended particulate of density ratio water is removed from water, is one of most widely used processing unit in sewage disposal, for operations such as the post processing of sewage disposal, biological treatment and advanced treating.But natural sedimentation is not only chronic, conventionally also there is thick and heavy precipitation blocking zone in water body, and suspension is many, water body chaos, so static sedimentation pond has floor space large, basin's effective volume is little, spoil disposal difficulty, the shortcoming such as treatment effeciency is low.How to make full use of natural sedimentation, shorten its precipitation clarification time, improve purifying rate?
Parallel pipe or parallelpiped (sometimes can utilize honeycomb filler) that tube settler utilization is tilted are divided into a series of shallow layer precipitating layers by water body, the motion separated mutually in each precipitation shallow-layer of the heavy mud of processed water body and sedimentation.Have desilting area large, the advantage such as deposition efficiency is high, the sedimentation time is short, occupation of land is few, is a kind of High-rate sedimentation equipment, is widely used in Small Town Wastewater treatment plant.But when water body solid loading is excessive, its treatment effect less stable; The ability of anti impulsion load is also poor.Especially serious is, and its swash plate (pipe) easily occurs that mud sticks, obstruction and algae multiply phenomenon, to maintenance management work, brings difficulty, and this has limited its scope of application greatly.
The type of precipitation can be divided into four classes according to the character of deposit, flocculability, concentration.
(1) free sedimentation
Particle is discrete state in precipitation process, does not interfere with each other, and its shape, size, density etc. all do not change, and subsidence velocity is constant.
(2) flocculation sediment
In water, concentration of suspension is not high, and flocculability particle condenses mutually, and its particle diameter and quality increase with the degree of depth, and the heavy speed of particle is accelerated.
(3) stratification precipitation
Be again (crowded precipitation).The concentration of flocculability particle in water is larger, between particle, flocculates, and between particle, mutually interferes, and is netted suede body, forms the sharp interface of clear water and muddy water and moves down gradually.Settling velocity is exactly the speed that interface moves down.Settling velocity is slow.
(4) compression precipitating
When concentration of suspension is very high, particle contacts with each other, and is partly compressed thing support.In the Action of Gravity Field Xia, of upper strata particle lower floor, intergranular water is extruded, and sludge blanket is compressed.
Visible, free sedimentation, the heavy speed of flocculation sediment process is large, and deposition efficiency is high; Stratification precipitation (crowded precipitation), compression precipitating process is because of the supporting role of mutual interference and lower floor between particle, and heavy speed is low, and efficiency is low, is the bottleneck of precipitation process.If expand, extend free sedimentation, flocculation sediment process, dwindles or eliminates stratification precipitation, and compression precipitating process, must shorten the sedimentation time, improves deposition efficiency.But how expanding, extend free sedimentation, does flocculation sediment process, dwindle or eliminates stratification and precipitate, compression precipitating process?
Stratification precipitation (crowded precipitation), the maximum feature of compression precipitating process is exactly between particle, mutually interfere and have a lower layer support effect.The supporting role between breakable layer, just could dwindle or eliminate stratification precipitation, compression precipitating process if can impact with hydraulic action, destroy intergranular mutual interference effect!
Especially stratification precipitates (crowded precipitation), and because aerosol density is large, viscosity is large, and suspended particulate is interfered mutually.Suspended particulate is subject to the balanced action of gravity, buoyancy, water resistance and the mutual interference drag of network-like particle in water, is netted suede body, forms the sharp interface of clear water and muddy water, and subsidence velocity is very slow.
If produce relative sliding displacement between water layer, on the one hand, with layer floccule body along continuous straight runs, move in the same way, extruding mutually, floccule body quality, density increase with the increase of hydraulic action; On the other hand, the supporting surface slippage dislocation between levels, retardance balancing network is sheared destruction, and supporting role disappears, and balance factor changes, and system is unbalance, causes caving in of whole system.
The upper strata downward ballistic motion of floc sedimentation of caving in, micelle is enlisted the services of in winding on the way, forms larger, more real flco, the constantly quickening of heavy speed.Its process nature is exactly flocculation sediment! Cave in impact, the squeezing action of material, extrude interaction particle intermediate gap liquid, and solid particle group is concentrated.
Hence one can see that, and flocculation sediment process can be expanded, be extended to the relative sliding displacement between water layer effectively, effectively dwindles or eliminate stratification precipitation, and compression precipitating process, shortens the sedimentation time, improves deposition efficiency.
Fluid movement is divided into laminar flow and turbulent flow (turbulent flow).During Reynolds number less (Re<2320), the impact of viscous force stream field is greater than inertia force, in flow field, the disturbance meeting of flow velocity decays because of viscous force, fluid layering flows, and the momentum-exchange that adjacent fluid interlayer only has molecular thermalmotion to cause, does not mix mutually, particle is made level and smooth rectilinear motion, the track of fluid micellar does not have obvious irregular fluctuation, and fluid flows stable, is laminar flow; Otherwise, when if Reynolds number is larger, the impact of inertia force stream field is greater than viscous force, fluid flowing instability, the minor variations of flow velocity easily develops, strengthens, and forms disorderly, irregular Turbulent Flow Field: streamline is clear can distinguishing no longer, in flow field, there are many little whirlpools, laminar flow is destroyed, not only has slip between adjacent fluid layer, also has and mixes; Fluid is done irregular movement, has the component velocity perpendicular to runner direction to produce, and is turbulent flow, or turbulent flow.
Design one and turn shaft-driven eccentric rotating cylinder settling vessel, due to the eccentric setting of rotating cylinder settling vessel, the centre of gyration is all not identical to the radius vector everywhere of pool wall.When rotating cylinder rotates, eccentric barrel is radially producing displacement (barrel to the radial distance of the centre of gyration increases or shortens), and barrel shape forces the centrifugal or centripetal flow of fluid, forms continuously fluid laminar motion.
Core of the present invention is while utilizing rotating cylinder to rotate, the eccentric barrel of all directions is to the difference of the radius vector of the centre of gyration, and eccentric barrel is constantly radially producing displacement, forms desirable laminar flow and (does not produce viscous flow, backflow, shunting, discrimination stream, fluid micellar track keeps in the same way, there is no irregular fluctuation).Utilize the hydraulic action of laminar flow, eliminate precipitation blocking zone, dwindle or eliminate crowded precipitation and compression precipitating process, improve and precipitated efficiency.For guaranteeing the generation of the laminar flow of perfect condition, the present invention designs rotating cylinder bias and connects with rotating shaft, forms Plane Rotation mechanism.Eccentric cylindrical shell is center rotating around the shaft, has guaranteed that pond Ti, Chi Shui, only at the flat in-plane moving being parallel to each other, does not produce horizontal shunting.
Summary of the invention
For solving tradition precipitation construction, maintain static, can only passively realize gravitational settling, cannot eliminate precipitation blocking zone, the state of inefficiency; And spoil disposal difficulty, needing additional configuration spoil disposal special equipment, cost is high; Tube settler is not strong to water yield impact load and water temperature variation adaptive capacity; Easily there is mud and stick, stop up in tradition swash plate (pipe), affect the defect of sedimentation effect, the present invention utilizes laminar motion characteristic, and comprehensive shallow pool theory, dynamic flocculating principles and swash plate technology, be fixedly connected the activity settlement of sewage device bias with swash plate in rotating shaft.While utilizing rotating cylinder to rotate, because barrel is not identical to the radius vector of the centre of gyration everywhere, barrel is constantly radially producing displacement (barrel to the radial distance of the centre of gyration increases or shortens), and barrel periodically forces the centrifugal or centripetal flow of fluid, forms continuously fluid laminar motion.Laminar motion accelerated with layer, interlayer suspend wadding core collision, stick, crosslinked, form more big flocculating body and precipitate; Scavenger precipitation blocking zone, accelerates precipitation process, and clarification water body, improves wastewater treatment efficiency, forms laminar flow precipitation effect.。
Equidistant or displacement is arranged in parallel, the arc plate group of overlapping combination, along settlement of sewage device axis horizontally set, axis or coincidence parallel with rotating cylinder body axis, is fixed on rotating cylinder inside.Adjacent arcs plate is divided into different unit by former moisture, and between arc plate, gap forms shallow layer precipitating pond one by one, and the sediment of processed water body and sedimentation is stable motion separated mutually in precipitation shallow-layer.
The present invention has changed the actionless state of traditional swash plate (pipe).Along with the rotation of rotating shaft, reducing rotary panel is done variable motion, and the precipitation floc sedimentation on solid-liquid borderline region is had to the souring that work is very strong, can avoid sediment on swash plate, to deposit, stick.
The technical solution adopted for the present invention to solve the technical problems:

The specific embodiment
In the embodiment shown in fig. 1, drum-type settlement of sewage device (1) bias of Horizontal band swash plate of the present invention connects with rotating shaft (4), rotating cylinder (1) is shaped as circular table shape, in cylinder, connect firmly one group be parallel to each other, the circular table arc plate (2) of overlapping arrangement, arc plate group (2) axis and the parallel coincidence of rotating cylinder body (1) axis.The barrel of circular table and circular table arc plate are arranged parallel to each other, and are right low left high and are fixed in parallel to each other body inside, pond.Adjacent arcs plate and barrel and arc plate form the inclined pipe structrue of several right low left highs in the axial direction.
Former water (11) flows into from body right side, pond water inlet pipe (10), to left movement, from the delivery port (6) in left side, overflows, and enters rhone (9), is transported to subsequent processing.
Because the arc plate left end of parallel overlapping arrangement arc plate group (2) the superiors exceeds the water surface, limited flowing of upper strata water body.The sewage (11) flowing into from water inlet (10), be subject to the restriction of the parallel overlapping arrangement arc plate group (2) of the overlapping arrangement of right low left high, the inclined pipe structrue clearance space that flows to respectively right low left high between the parallel arc plate of parallel overlapping arrangement arc plate group (2), moves along arc sheet separation space divergence.When the large particle of component velocity that makes progress will move upward, limited by the lower surface of the arc plate of internal layer inclination expansion, can only move along arc wooden partition face.And the viscosity on solid-liquid border is maximum, just can exhausts energy soon and sink.To the large particle of both sides component velocity, by both sides arc plate, limited, before solid-liquid border, stop.The particle that the speed that travels forward is large be also subject to skin be inclined upwardly expansion arc plate upper surface limit, also can exhaust energy on solid-liquid border.So between the adjacent arcs plate of parallel overlapping arrangement arc plate group (2), between arc plate and barrel, form the shallow layer precipitating pond that several length are very long, the sediment (12) of processed water body (11) and sedimentation is stable motion separated mutually in precipitation shallow-layer.Solid-liquid borderline region is to accelerate the main region that precipitation forms.
Even, there is too precipitation blocking zone in shallow layer precipitating pond, just size, position and the stability of blocking zone different and.Blocking zone inner suspension thing density is large, and viscosity is large, and the mutual interference effect of suspended particulate increases, particle in water, be subject to gravity, buoyancy and water resistance, the mutual interference drag of particle balanced action, subsidence velocity is very slow.
Tradition precipitation construction fixed static is motionless, can only passively realize gravitational settling, cannot eliminate precipitation blocking zone, so inefficiency.
The present invention drives rotating cylinder to rotate by rotating shaft (4).Due to the bias design of rotating cylinder (4), barrel is not identical to the radius vector of the centre of gyration everywhere, and radius vector presents continuously variation.In half gyration period, the barrel of a side constantly approaches from the centre of gyration, and respective side barrel from the centre of gyration constantly away from; Approach side the dischargeable capacity of water body is reduced gradually, away from side, the dischargeable capacity of water body is increased gradually, approach side tube-wall and force water body to away from side flow; In revolution, enter another half gyration period, original radius vector away from side constantly shortens, and barrel is close to the centre of gyration gradually, becomes and approaches side; And original radius vector that approaches side constantly increases, barrel is gradually away from the centre of gyration, become away from side, corresponding two side tube-wall kinetic properties are changed mutually, and water body flows to original side (present away from side) side that approaches from original away from side (present approach side) again ...So the gyration that eccentric rotating cylinder (1) goes round and begins again, impels fluid constantly repeatedly from an effluent to opposite side, form the laminar motion constantly moving left and right.
Suspension wadding core between same water layer is with water sports, and because the suffered resistance of different scale particle is different, the particle between different scale produces speed difference.Fireballing wadding core is caught up with slow-footed wadding core, and the cohesion that collides with each other forms larger floccule body.
The wadding core that some movement velocitys are fast, they do not have and other wadding core contact-impact chances on the way yet, take the lead in moving near pool wall.Hindered by pool wall boundary layer fluid viscous effects and pool wall shape, near pool wall, assemble on border gradually, and wadding cuclear density improves gradually, and spacing is more and more less.Wadding core is assembled, and density improves, and spacing is dwindled, and favourable wadding is internuclear sticks, crosslinked, coalescent formation large scale, large quality, firm, closely knit big flocculating body and precipitate.
What finally arrive is large-sized wadding grain, and it has huge surface area, remaining gathering micelle net is caught, is rolled up and sweep the closely knit big flocculating body of formation, and precipitate.
There is speed difference in adjacent water layer, the particle speed of fireballing water layer is fast, and they scanned aspect, is easy to catch the slow particle of movement velocity in adjacent bed, is combined into large wadding grain.
The grain of no matter wadding a quilt with cotton is big or small, and speed, under the acting in conjunction of tangential waterpower and gravity, is assembled to the two side lower parts motions of pond body by pool center gradually.Near pool wall, borderline region is to accelerate the main region that precipitation forms.
Layer fluid interlayer relative sliding, particle is along aspect relative motion, and balancing network is sheared displacement, bearing-surface slippage dislocation, supporting role disappears, and system is unbalance, and network equalize system is caved in.The upper strata downward ballistic motion of floc sedimentation of caving in, micelle is enlisted the services of in winding on the way, forms greatlyr, and more closely knit precipitation flco is separated with water, makes former water be able to defecate and purify.
Layer fluid relative sliding constantly on left and right directions, the retardance balance of precipitation blocking zone is constantly sheared destruction, and unbalance retardance system is constantly caved in, and solid particle group is also constantly aggregated concentrated.Therefore the rotary action of eccentric rotating cylinder (1) is purified former water (11) repeatedly, sedimentation separation is thorough, and suspension reduces greatly.
There is deposition groove (13) on settling vessel right side, and parallel arc plate right low left high ground tilts to deposition groove (13), is beneficial to sediment (12) and to deposition groove (13) slippage, collects gradually.
Parallel overlapping arrangement arc plate group (2) axis is parallel with rotating cylinder body (1) axis or overlap, and reducing arc plate action principle is identical with reducing wallboard (1).
The present invention has changed the actionless state of traditional swash plate (pipe).Reducing wallboard (1), reducing arc plate rotate and do variable motion with rotating shaft (4), and the precipitation floc sedimentation on solid-liquid borderline region is had to the souring that work is very strong.Along with pond body (1) constantly rotates, under the sliding force component double action that constantly change is large of tangentially sluicing effect and precipitation flco (12) deadweight, floc sedimentation (12) slip viscous drag reduces greatly.Tangential waterpower and downslide component constantly drive flco along the downward sliding motion of cambered surface, are finally slipped to right side deposition groove (13), have avoided sediment on arc plate, to deposit, stick phenomenon.
In the embodiment shown in fig. 6, the drum-type settlement of sewage device rotating cylinder body (1) of vertical band swash plate of the present invention is by sliding bearing (17) supporting on pedestal (20), and rotating cylinder (1) bottom has rotating shaft (4) and its bias to connect; Rotating cylinder (1) is shaped as circular table shape, in cylinder, connect firmly one group be parallel to each other, circular table arc plate (2), arc plate group (2) axis and rotating cylinder body (1) dead in line of overlapping arrangement.The barrel of circular table and circular table arc plate are arranged parallel to each other, and barrel bus and circular table arc plate bus all tilt to axle center.Between the adjacent arcs plate of parallel overlapping arrangement arc plate group (2) and arc plate and rotating cylinder (1) barrel, on longitudinal cross-section, form several inclined pipe structrues.
Sewage (11) enters in pond from top to bottom by the water inlet pipe (10) that is located at center, pond, the lower umbrella-shaped baffle (18) of pipe evenly spreads sewage (11) level, then flows up into respectively the inclined pipe structrue clearance space between parallel overlapping arrangement arc plate group (2) adjacent arcs plate plate.Upwards the large particle of component velocity moves upward, and limited by the inner surface of the arc plate of outer centroclinal dip expansion, can only move along arc plate inner wall surface.And the viscosity on solid-liquid border is maximum, just can exhausts energy soon and sink; The particle that horizontal component velocity is large, is limited around arc plate by ectonexine, before solid-liquid border, stops.The shallow layer precipitating pond of inclined pipe structrue, makes sediment (12) stable motion separated mutually in precipitation shallow-layer of processed water body (11) and sedimentation.Solid-liquid borderline region is to accelerate the main region that precipitation forms.
In like manner, rotating shaft (4) drives rotating cylinder (1) to rotate.On any axis vertical plane, the barrel of eccentric design also presents that synchronism ground approaches continuously or away from the centre of gyration.Approach side the dischargeable capacity of water body is reduced gradually, away from side, the dischargeable capacity of water body is increased gradually, approach side tube-wall and force water body to away from side flow.Go round and begin again, fluid, constantly repeatedly from an effluent to opposite side, forms the laminar motion constantly moving left and right.Laminar motion not only accelerate with layer, interlayer suspend wadding core collision, stick, crosslinked, form more big flocculating body and precipitate; And can constantly destroy retardance balance, and scavenger precipitation blocking zone, accelerates precipitation process repeatedly, and clarification water body, improves wastewater treatment efficiency.
The drum-type settlement of sewage device of vertical band swash plate is to the scavenging action of precipitation blocking zone and the effect equivalence to the precipitation souring of flco and the drum-type settlement of sewage device of Horizontal band swash plate.
The bottom of the drum-type settlement of sewage device of vertical band swash plate is deposition groove (13), collecting precipitation dirt, and the mudhole (14) on deposition groove (13) is in order to discharge precipitation dirt.
No matter be horizontal, vertical, can not pass through left-right rotation rotating shaft repeatedly fast, will on arc plate face, form the shear flow of strong turbulence, can cause high speed souring to swash plate, remove possible alluvial, stop up very convenient.
