Description
Technical field
This practicality newly relates to sewage Environmental-protecting treater, is specifically related to a kind of for trade effluent and the dirty Novel jet aerator processed of municipal administration.
Background technology
Jet-flow aeration is a kind of aeration mode of current biochemical wastewater treatment application.Jet aerator, neither a kind of mechanical aeration equipment neither a kind of bubble diffusing apparatus, but a kind of aerator between both, utilizes bubble to spread and these two effects of hydraulic shear reach the object of aeration and mixing.It has good oxygen transfer: coefficient of oxygen utilization is up to 15% ~ 30%; Effective gas dispersion and higher mass transfer coefficient, dissolved oxygen and bubble distribution evenly, effectively reduce dead band; Manufacture simple, easy to maintenance, appropriately combined being convenient to regulates.
But the main drawback of the jet aerator of prior art comprises:
(1) produce larger shearing stress, be unsuitable for the use in stress sensitive environment;
(2) structure is comparatively complicated, easily blocks;
These shortcomings can cause the decline of aeration tank biological treatment effect, and oxygen-transfer efficiency declines, thus increase the increase of blast volume, and running cost increases severely.
Utility model content
For above-mentioned defect, the utility model object be to provide a kind of structure simple, blocking is less likely to occur, the jet aerator of the shearing stress that jet produces can be reduced.
In order to achieve the above object, the utility model adopts following technical scheme:
Novel jet aerator, comprise ejector fixed installation body, be respectively arranged with inlet mouth and water-in at the two ends of described ejector fixed installation body, in described ejector fixed installation, body is tilted is provided with multiple ejector open holes, and tube-type fluidic device is installed in described ejector open holes; In the fixed installation of described ejector, body is tilted is provided with retaining wall, air intake passage is formed between the upper surface of described retaining wall and inlet mouth, described air intake passage is connected with tube-type fluidic device inlet mouth, form water inlet passageway between the lower surface of retaining wall and water-in, described water inlet passageway is connected with tube-type fluidic device water-in.
One as the utility model Novel jet aerator is improved, and the same level in described ejector fixed installation body is evenly also provided with multiple ejector open holes obliquely, and tube-type fluidic device is installed in described ejector open holes.Such tube-type fluidic device just can spray by 360 ° of omnibearing stereos, guarantees without dead angle in aeration tank, improves the dissolved oxygen efficiency of 20% than conventional fluidic aerator.
Another kind as the utility model Novel jet aerator improves, and be provided with nozzle in the water-in of described tube-type fluidic device, the diameter of described nozzle from large to small; Thus liquid in nozzle with high speed from nozzle ejection out, to ensure the mixed effect of liquid and air.
As another improvement of the utility model Novel jet aerator, in the nozzle of described tube-type fluidic device, anti-clogging plug spiral is installed.By being provided with anti-clogging plug spiral in nozzle, being namely adopt clog-free structure, being specially adapted to calcium ions more, easily causing the trade effluent (as paper waste) of fouling and clogging to process.
From the above, the utility model compared with prior art, has following beneficial effect:
Novel jet aerator of the present utility model compares traditional jet aerator, reduces jet and produces larger shearing stress, dissolve in more air, produce more small bubbles; Tube-type fluidic device adopts and tilts to install, and makes full use of fluid gravity effect, reduces drag losses; 360 ° of omnibearing stereos spray, and guarantee without dead angle in aeration tank, improve the dissolved oxygen efficiency of 20% than conventional fluidic aerator; Adopt clog-free structure, be specially adapted to calcium ions more, easily cause the trade effluent (as paper waste) of fouling and clogging to process.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of Novel jet aerator of the utility model;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the structural representation of tube-type fluidic device;
In figure: 1 ejector fixed installation body, 2 inlet mouths, 3 water-ins, 4 tube-type fluidic devices, 5 retaining walls, 6 air intake passages, 7 water inlet passageway, 40 tube-type fluidic device inlet mouths, 41 tube-type fluidic device water-ins, 42 nozzles, 43 anti-clogging plug spirals, 44 tube-type fluidic device mixing sections.
Embodiment
Accompanying drawing, only for exemplary illustration, can not be interpreted as the restriction to this patent.
To those skilled in the art, in accompanying drawing, some known features and explanation thereof may be omitted is understandable.
Below in conjunction with the Figure of description in the utility model, be clearly and completely described the technical scheme in utility model, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1-2, for the structural representation of the Novel jet aerator of the utility model preferred embodiment, comprise ejector fixed installation body 1, inlet mouth 2 and water-in 3 is respectively arranged with at the two ends of this ejector fixed installation body 1, during use, inlet mouth 2 and water-in 3 are connected compressed air pipe (not shown) and circulating jet pipe (not shown) respectively; Same level in this ejector fixed installation body 1 is evenly also provided with multiple ejector open holes obliquely, and tube-type fluidic device 4 is installed in this ejector open holes; Wherein, this ejector fixed installation body 1 tilted be provided with retaining wall 5, form air intake passage 6 between the upper surface of this retaining wall 5 and inlet mouth 2, as shown in figs. 1 and 3, this air intake passage 6 is connected with tube-type fluidic device inlet mouth 40; Form water inlet passageway 7 between the lower surface of retaining wall 5 and water-in 3, this water inlet passageway 7 is connected with tube-type fluidic device water-in 41.
