Description
Technical field
The utility model relates to a kind of efflux aerator.
Background technology
Aeration refers to and amasss with to the method such as Aeration in the water or mechanical agitation increase water and air contact surfaces, is the middle process of waste water aerobiont process.
Generally adopt micro-pore aeration method on the market now, and As time goes on the shortcoming of micro-pore aeration method is exactly, oxygen-transfer efficiency can be more and more lower, and overhaul inconvenience later.
Jet-flow aeration method refers to that the mixed solution of sewage and mud composition passes through ejector, produce negative pressure due to high-speed jet, thus have a large amount of air intakes, air fully contacts with mixed solution, improve the oxygen inhalation rate of sewage, thus the sewage efficiency of process is improved.The performance that the efflux aerator of recent development demonstrates in oxygen transfer, dissolved oxygen speed, utilising efficiency etc., but the stability of its oxygen-transfer efficiency and long-play state needs to improve further.
Utility model content
In order to overcome the deficiency that prior art exists, the utility model provides that a kind of oxygen-transfer efficiency is high, the efflux aerator of good stability.
A kind of efflux aerator, comprise ejector and jet-pump, described ejector comprises water inlet pipe, inlet pipe, mixing wastewater with air room and diffuser tube, passes through pipeline communication between ejector and jet-pump, described mixing wastewater with air chamber interior walls is provided with some flow-disturbing grooves, and the exit of diffuser tube is provided with wire netting.
As preferably, a jet-pump is connected with two ejectors respectively.An ejector different from the past needs a corresponding jet-pump, and ejector can carry out flexible according to on-site actual situations, can adopt a pond one or more jet-pump corresponding, can also adopt one or more jet-pump in multiple pond; And jet-pump adopts a corresponding ejector or multiple stage ejector; The adjustment that the synergistic nozzle quantity that ejector is corresponding also can be carried out according to on-site actual situations or increase or subtract.
As preferably, the mesh size of described wire netting is 6mm.The bubble ejected is carried out secondary cut, and bubble is less, increases gas-water contact area, and therefore, its oxidation effect is improved; Prove through test, under the same conditions, mesh size is set to 6mm, its oxidation effect can reach best.
As preferably, described diffuser tube is tapered tube, and its tapering is 30 °.The tapering of diffuser tube also can produce material impact for oxidation effect.
This utility structure is simple, reasonable in design, the design of flow-disturbing groove, when mixing wastewater with air liquid flows through herein, can produce high-speed eddy at this, blending, air is divided into countless micro-bubbles and pressurized water sprays in the lump, the micro-bubble of such generation just improves the contact area of gas-liquid two-phase, reaches the object of highly effective oxygen dissolving; The design of wire netting, bubble can be divided into small bubbles further, and expand the contact area of water and gas, thus oxidation effect improves further; The utility model has that ejector inhalation flow is large, oxygen transfer efficiency is high, long-time running good stability, take up an area less, the advantage such as cost is low, long service life.

Principle of work of the present utility model is: the water sprayed through water inlet pipe 3 mixes in mixing wastewater with air room 5 with the air of coming in from inlet pipe 4, inwall due to mixing wastewater with air room 5 is provided with flow-disturbing groove 7, when mixing wastewater with air liquid flows through herein, high-speed eddy can be produced, blending, air is divided into countless micro-bubbles and pressurized water sprays in the lump, and the micro-bubble produced so just improves the contact area of gas-liquid two-phase, reaches the object of highly effective oxygen dissolving; The bubble produced after mixing wastewater with air room 5 mixes and water slow down step-down in diffuser tube 6, and when by wire netting 8, bubble is cut into small bubbles further, expand the contact area of water and gas, oxidation effect is improved further.
Embodiment 2
With reference to Fig. 2, a kind of efflux aerator, comprise ejector 1 and jet-pump 2, described ejector comprises water inlet pipe 3, inlet pipe 4, mixing wastewater with air room 5 and diffuser tube 6, pipeline communication is passed through between ejector 1 and jet-pump 2, described mixing wastewater with air room 5 inwall is provided with some flow-disturbing grooves 7, the exit of diffuser tube 6 is provided with wire netting 8, the mesh size of described wire netting is 6mm, the bubble ejected can be carried out secondary cut, bubble is less, increases gas-water contact area, therefore, its oxidation effect is improved; In order to improve oxidation effect further, described diffuser tube is tapered tube, and its tapering is 30 °.
A jet-pump is connected with two ejectors respectively.An ejector different from the past needs a corresponding jet-pump, and ejector can carry out flexible according to on-site actual situations, can adopt a pond one or more jet-pump corresponding, can also adopt one or more jet-pump in multiple pond; And jet-pump adopts a corresponding ejector or multiple stage ejector; The adjustment that the synergistic nozzle quantity that ejector is corresponding also can be carried out according to on-site actual situations or increase or subtract.
