The air ejection pure oxygen disperses the high efficient aeration device
Technical field
The utility model is relevant with water treating equipment, particularly a kind of aerating apparatus that is used for various dirts, waste water and aquaculture water treatment.
Background technology
Can airborne oxygen be dissolved in the water the efficient and the decontamination effect improving that how much directly affect WWT of dissolved oxygen amount through aeration.In order to increase coefficient of oxygen utilization, make bubble in small, broken bits, micro-pore aeration has obtained popularizing.The aperture of aerator is small more, and the bubble of generation is also just in small, broken bits more, contacts area between gas-liquid thereby increased, and coefficient of oxygen utilization increases; But the aperture is thin more simultaneously, and atmospheric pressure lost is also big more, is prone to stop up, and aerator is fragile, in case damage, oxygen transfer efficiency just begins quick decline.In addition, aerator is installed in the aeration tank with dot matrix, though the microbubble of generation is dissolved in the sewage as much as possible, is prone to float, and probiotics and sewage in the pond are fully mixed, thereby has influenced the effect of WWT.
The utility model content
In order to overcome above-mentioned defective and deficiency, the utility model provides a kind of aerating apparatus that oxygenation and agitating function and oxygen-transfer efficiency are high, be difficult for obstruction, long service life that integrates.
For solving the problems of the technologies described above, the utility model provides a kind of air ejection pure oxygen to disperse the high efficient aeration device, comprises aerator, the inlet pipe that is connected with aerator and leg.Said aerating apparatus comprises three legs, and wherein two is aeration tube, is respectively to promote aeration tube and oxygenic aeration pipe; Aerator and inlet pipe unite two into one, and aerator comprises that air ejection and pure oxygen disperse two cover airing systems.Wherein said air ejection airing system comprises the air ejector of ring, a vertical setting in the vertical middle tube, and said air ejector is taked straight-through air air feed, vertically places in the tube and encircles; Said pure oxygen disperses airing system to comprise eight aeration plates, the gas-filled valve that is attached thereto and vertically middle tube outer shroud, adopts the micropore pure oxygen aeration.
Wherein said aerator leg can directly link to each other with pond base plinth by stainless steel lathe dog; And it is fixing by bolt and middle tube.
Lifting aeration tube in the said leg inserts tube in the said aerator by the bottom; Oxygenic aeration pipe in the said leg is supplied with said eight aeration plate pure oxygens through the peripheral gas-filled valve of ring tube.
The vertically middle tube of said aerating apparatus is the both ends open formula, and middle 1/3 is three-dimensional column structure with top, is the annulus three-dimensional arrangement of sealing with the lower section.
Said air ejector is communicated with the lifting aeration tube, vertically places in the tube, is positioned at annulus.
Said air ejector is the inner chamber with a both ends open, uniform distribution gross blow hole on the inner chamber.
It is petal-shaped that said pure oxygen disperses eight aeration plates of airing system, and every aeration plate links to each other with a gas-filled valve respectively, uniform ring around the air ejection airing system vertically in a layout.Tube outer shroud in the common access vertically of said each gas-filled valve and oxygenic aeration pipe.
Said air ejection pure oxygen disperses the high efficient aeration device to adopt the high density polyethylene(HDPE) material.
After adopting above structure, the utility model aerating apparatus has following advantage:
Owing to be cut into micro bubbles by aeration plate in the air-flow uphill process, increased contact area with sewage; Aeration plate adopts pure oxygen aeration, has increased the oxygen impellent, has further improved oxygen-transfer efficiency; Because the source of the gas of molecular sieve oxygen generation is a screw-rod air compressor, compares with the other types blower fan, its air pressure is bigger, and air-flow is more stable, thereby can not stop up; In addition, aeration plate has also played the effect of even gas distribution.
In air ejector, compressed air stream upwards dashes the lifting aeration tube with a large amount of blast injections, can take a large amount of sewage and loosening mud out of, feasible water-bed mud and the stirring of sewage thorough mixing.Thereby the contacting of aerobic bacteria and oxygen in the increasing mud strengthens biological activity, improves sewage treatment capacity and scrubbing efficient.
Because aerator adopts the high density polyethylene(HDPE) material, thereby prolong the work-ing life of aerating apparatus, practiced thrift cost.

Embodiment
Below in conjunction with accompanying drawing the utility model is done further explanation.
As shown in Figure 1, the utility model is that a kind of air ejection pure oxygen disperses the high efficient aeration device, comprises aerator, the inlet pipe that is connected with aerator and leg.Wherein said aerator comprises that air ejection and pure oxygen disperse two cover airing systems; Tube 1 periphery during said three legs are evenly distributed on vertically, leg closely is connected with middle tube barrel through bolt 9, plays dual function fixing and gas transmission; Aeration plate 3 is connected with middle tube 1 through gas-filled valve 4, and aeration plate 3 is aggregate erection with gas-filled valve 4.
Two is inlet pipe in the said leg, is respectively to promote aeration tube 7 and oxygenic aeration pipe 8; Said lifting aeration tube 7 inserts tube 1 in the aerator by the bottom, works to promote bed mud; Said oxygenic aeration pipe 8 is supplied with aeration plate 3 pure oxygens through the peripheral gas-filled valve 4 of ring tube.
Shown in Figure 2 through section, vertically middle tube 1 is three-dimensional circular, and its outer shroud 5 is the both ends open formula, and interior ring 6 is closed.
Said air ejection aerating system comprises the vertically air ejector 2 of setting of the interior ring 6 and of a vertically middle tube.Wherein said air ejector 2 is arranged in tube ring 6, and lifting aeration tube 7 passes outer shroud 5 and directly is communicated with injector 2.Promote aeration tube 7 with compressed air delivery to air ejector 2, air dispersion is an air pocket.Under intensive impacts, can take a large amount of sewage and mud out of, make muddy water fully stir.
Said pure oxygen disperses aerating system to comprise eight aeration plates 3, the gas-filled valve 4 that is connected with aeration plate 3 and vertically middle tube outer shroud 5.The gas-filled valve 4 and the said oxygenic aeration pipe 8 that connect aeration plate 3 directly are communicated with a vertical middle tube outer shroud 5.Through the pure oxygen of oxygenic aeration pipe 8 entering outer shrouds 5, get into aeration plates 3 through each gas-filled valve 4 again, be divided into micro-bubble, increased the gas-to-liquid contact area, coefficient of oxygen utilization strengthens.Simultaneously, the impellent of pure oxygen is strong than air, and surging force is big, the generation that can reduce to stop up.
The enforcement of the utility model can improve coefficient of oxygen utilization, strengthens the stirring action between mud and the water, and mikrobe is further contacted with oxygen, strengthens its activity, obtains good wastewater treatment efficiency.
