The present invention relates to a kind of sewage disposal device accessory, particularly a kind of jet aerator.
Background technology
Early 1980s, biotechnology (being immobilized microorganism technique) starts to be applied to biochemical processing procedure of sewage, along with the development of biologic treating technique, the typical process of biological wastewater treatment---aerobic treatment technique is widely used in waste water treatment engineering.As crucial oxygen replenishing equipment---the aerator in aerobic treatment technique, its Biochemical Treatment to waste water plays vital effect.There is the defects such as air demand is little, coefficient of oxygen utilization is low, and maintenance management difficulty is large, maintenance rate is high in the aerator of at present domestic production (diaphragm type aerator, tube aerator, revolve mixed aerator, boring aeration device etc.).These traditional aerators are in being applied to not high, the small-sized sewage treatment project of processing requirements, its treatment effect taste can, but for big-and-middle-sized sewage treatment project, its treatment effect is just obviously not enough, and maintenance rate is too high, does not reach the technical requirements in technological design.
Summary of the invention
Goal of the invention: for the deficiencies in the prior art, the invention discloses a kind of air demand large, the simple jet aerator of utilization ratio high maintenance.
Technical scheme: the invention discloses a kind of jet aerator, comprise outer chamber, and outer chamber coaxial be arranged on the inner chamber body in outer chamber; Described outer chamber upper end is provided with inlet mouth, and inner chamber body lower end is provided with water-in, and described water-in stretches out outer chamber lower end; Described inner chamber body surrounding is provided with one group of inner nozzle, and outer chamber surrounding is provided with one group of outer nozzle.
Wherein, described one group of inner nozzle is at least ten, and described outer nozzle is at least 10, the quantity one of described inner nozzle and outer nozzle to.
Wherein, the corresponding supporting setting of described inner nozzle and outer nozzle, corresponding inner nozzle and the cavity between outer nozzle are hybrid chamber.
Wherein, described inner chamber body is for being formed by laterally zygomorphic two dish-shaped housing bondings; Described outer chamber is for being formed by laterally zygomorphic two dish-shaped housing bondings.
Jet aerator of the present invention, interior outer chamber is the involutory bonding cavity forming of upper and lower two butterfly housings, interior outer chamber coaxial sleeve closes, and fluid inlet is connected respectively inner chamber and exocoel with inlet mouth along axis direction, and inner and outer nozzles is uniform with one heart along inside and outside cavity side face respectively.Inner chamber is working medium chamber, and exocoel is injection medium suction chamber, is hybrid chamber between inner and outer nozzles.Aerator self is not containing any electromechanical component and drive disk assembly.
For making aerator have the powerful oxygen ability of rushing, the present invention has adopted 10 double-deck nozzles.Consider reciprocal influence between each nozzle, the distribution of nozzle adopts radially equal angles radial arrangement of circle.This layout can be avoided the phase mutual interference between jet to greatest extent, reduces bubble poly-phenomenon, is conducive to improve coefficient of oxygen utilization.
Obvious feature of the present invention is that hybrid chamber (outer nozzle) is nozzle-like, has formed one group of dual nozzle with working medium nozzle (inner nozzle).The major cause that hybrid chamber is designed to nozzle-like has four: the one, because this structure can meet the requirement that coefficient of oxygen utilization improves.Reducing to clash into lose needs the velocity contrast between gas-liquid as far as possible little, but velocity contrast is less, and liquid is just more weak to the cutting action of gas, and coefficient of oxygen utilization is just lower.When hybrid chamber becomes nozzle-like, inlet area is larger, and the flow velocity of air is just low, and just large with the velocity contrast of liquid, cutting action is just strong; Hybrid chamber outlet is less, and the flow velocity of air is just high, just little with the velocity contrast of liquid, and shock loss is just little.The 2nd, because this structure utilizes the kinetic energy of mixed solution to realize second spraying, put forward high-octane service efficiency.There is larger velocity contrast in the liquid outside mixed solution and nozzle, can produce strong secondary cut effect.The 3rd, because this structure is conducive to the formation of liquid turbulent flow in pond, the utilization ratio of oxygen is further improved.The liquid Divergent Phenomenon of contraction-like nozzle ejection is obvious compared with straight tube nozzle, and the ability of carrying (being involved in) surrounding liquid is also strong, produces turbulent scope also large.The 4th, because this structure can reduce bubble diameter, increase the solubleness of water oxygen, improve the transmission speed of oxygen.The liquid of converging nozzle is dispersed flow velocity is reduced rapidly, and the kinetic energy of mixed solution transfers pressure energy to, and gas is compressed, diameter reduces gradually, the solubleness of water oxygen also increases, and the oxygen of air can be dissolved in gas-liquid mixed stream quickly and go, thereby improve the transmission speed of oxygen.
In equipment, the working medium of certain pressure (being generally the mixed solution of waste water or waste water and active sludge) ejects with very high speed through inner nozzle, forms the symmetrical jet beam of one high speed shaft.This strand of jet beam through induction chamber by the laggard hybrid chamber that enters ejector of certain stream distance.During this period, near working medium jet flow boundary and have the discontinuous gradually section of speed around between stationary fluid (air), gradually section is subject to high-speed jet bundle and inevitably disturbs, lose and stablize and generation vortex, entrainment ambient air and enter jet beam, constantly move simultaneously, be out of shape, divide, produce turbulent fluctuation, its impact is gradually to the development of inside and outside both sides, to jet beam center, spread on the one hand, also still air spreads towards periphery simultaneously, forms the mixolimnion of inside and outside two free turbulent fluctuations.The material on working medium border is accelerated, and air enters in jet, and in the jet expanding, be absorbed, acceleration, fusion and in the jet increasing.Therefore the air, contacting with this strand of high speed turbulent jet bundle is carried into mixing section by working medium.At this moment induction chamber is vacuum state, and outside air supplements into immediately endlessly.Entrainment the air entering and obtain momentum and travel forward in company with original fluid, fluid originally loses momentum and flow velocity reduction, has certain current gradient in mixolimnion, thereby forms the very strong shear force that subtracts.These shearing forces can be cut borderline eddy current, cause again fierce turbulent fluctuation simultaneously.This additional turbulent flow can promote the sufficient fluid mixing effect of very high oxygen transfer rate.Entrainment the result with blending effect, jet flow section is continuous, and flow velocity constantly reduces, and flow is but along Cheng Zengjia.The pressure energy of working medium changes kinetic energy at nozzle place, and a part of kinetic energy changes pressure energy in induction chamber, to supply with the use of injection air.Enter after mixing section, a part of kinetic energy of working medium passes to injection air again; In addition, the flow process of mixed stream in mixing section is due to violent turbulent fluctuation stirring and hydraulic shear, the speed that mass exchange between liquid and gas and transmission ofenergy effect make mixed stream is tending towards balanced gradually, and the kinetic energy that mixed stream occurs simultaneously changes pressure energy on the contrary into.
Air-flow mixed flow is sprayed and enters waste water with a higher speed by mixing section nozzle, owing to having larger velocity contrast with surrounding liquid, so still there is larger secondary cut effect, in addition, jet beam diffusion and flow velocity reduces rapidly, kinetic energy changes pressure energy into, cause pressure raw high, energy by liquid transfer to gas, liquid does work to gas compression, bubble diameter reduces gradually, and the increase of the solubility with pressure of oxygen and improving, and makes the oxygen of injection air can top speed and dissolve in to greatest extent in gas-liquid mixed stream and go.
In activated sludge process aeration tank bottom, from the bubble discharging to nozzle in jet aerator, finally at the water surface, vanish whole during have four mass transfer stages: in nozzle, form bubble; In level, to inertia, flow; Upwelling is moving in the vertical direction; The secondary turbulent flow being formed by hydraulic mixing mode.
Working medium forms a kind of milky air-water mixture with the very little bubble being sheared in hybrid chamber, through hybrid chamber nozzle ejection to time in aeration tank, can see that the strong thing of plumage of tiny bubble in, to all directions diffusion of aeration tank, now plays the oxygenation of general blast aeration.The mixture of the liquids and gases of here, discharging can be supplied with maximum oxygenation and turbulent stirring action.
From mass transfer process, the present invention is significantly more complex than blast aeration and mechanical aeration, is also more complex than negative pressure air feeding type jet aerator, and the approach that oxygen transmits is many, and therefore coefficient of oxygen utilization of the present invention is very high, and this is that other aerator is incomparable.
During aeration, strong gas stripping makes liquid circulation rolling in pond, completes oxygenation rapidly, mixing and stirring simultaneously.When stopping forced air supply, the logical inner nozzle of circulation fluid sprays at a high speed, around low speed liquid is strongly involved in and is carried out momentum exchange, be involved in part and add again injection main flow, go round and begin again, finally realize the mix and blend effect to liquid, now because no oxygen participates in making dish formula jet aerator have anaerobic agitating function.
Because the present invention is installed on the bottom of activated sludge tank, therefore no matter aerobic or anaerobic operation, all can reach good mix and blend effect, guarantees that active sludge is all the time in suspended state.
Beneficial effect: jet aerator disclosed by the invention, adopt unique interior exocoel second spraying technology, make gas-vapor mix more even; Equipment has enough large capacity, and the direct access arrangement inner chamber of air water ejects, and air demand is large; Due to useless water and air by nozzle ejection out, can make active sludge in aeration tank all the time in suspended state, guarantee that waste water fully mixes and contacts with active sludge, greatly improved the treatment effect of waste water; Adopt unique interior exocoel second spraying technology, make air water fully contact mixing, the utilization ratio of oxygen is provided greatly; Adopting high strength SS304 stainless steel is material, and antiseptic property is superior, and intensity is large, and easily moulding adopts welding manufacture, is convenient to realize batch production; Maintenance maintenance rate is low, almost nil maintenance, long service life.
