Technical field
The present invention relates to technical field of sewage, more particularly to a kind of micro-nano bubble generator.
Background technology
At present, in sewage disposal, it is sometimes desirable to the behaviour such as air supporting, oxygenation or ozone oxidation is carried out to processed sewage Make.However, it is existing realize above-mentioned processing device efficiency it is not high, and generally require at multiple stations set corresponding to handle Equipment, cause sewage disposal system complicated.
Therefore, in view of the above-mentioned problems, being necessary to propose further solution.
The content of the invention
It is an object of the invention to provide a kind of micro-nano bubble generator, to overcome present in prior art not Foot.
For achieving the above object, the present invention provides a kind of micro-nano bubble generator, and it includes：Intake pump, mix Clutch, jet blower, gas-liquid mixed tank, nozzle；
The intake pump is connected by pipeline with one end of the blender, and the other end of the blender passes through pipeline and institute State jet blower to be connected, the blender is also associated with loading line, and the jet blower is stretched into the gas-liquid mixed tank, and institute The inwall for stating jet blower towards the gas-liquid mixed tank is set, and the side wall of the bottom of the gas-liquid mixed tank is provided with outlet, institute State outlet by pipeline with the nozzle to be connected, the injection direction of the internal diameter of the nozzle along the nozzle is gradually reduced.
As the improvement of the micro-nano bubble generator of the present invention, the blender is venturi mixer.
As the improvement of the micro-nano bubble generator of the present invention, gas is additionally provided with the loading line of the blender Flowmeter body.
Being conveyed as the improvement of the micro-nano bubble generator of the present invention, in the loading line has purity oxygen or sky Gas or ozone.
As the improvement of the micro-nano bubble generator of the present invention, the jet blower is towards in the gas-liquid mixed tank Roof in wall is set.
As the improvement of the micro-nano bubble generator of the present invention, the jet blower body of the jet blower including L-shaped with And it is opened in the shower nozzle of the L-shaped jet blower body end.
Compared with prior art, the beneficial effects of the invention are as follows：The micro-nano bubble generator of the present invention is vdiverse in function, Its air supporting, water body oxygenation and ozone oxidation available for the sewage that is processed, and there is higher efficiency, fully meet sewage Processing actual demand, achieve preferable environmental benefit.
Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing There is the required accompanying drawing used in technology description to be briefly described, it should be apparent that, drawings in the following description are only this Some embodiments described in invention, for those of ordinary skill in the art, on the premise of not paying creative work, Other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is the floor map of an embodiment of the micro-nano bubble generator of the present invention, wherein, each knot The corresponding relation of structure and label is：Intake pump -1, blender -2, gas flowmeter -21, jet blower -3, gas-liquid mixed tank -4, go out Mouth -41, nozzle -5.
Embodiment
The present invention is described in detail for shown each embodiment below in conjunction with the accompanying drawings, but it should explanation, these Embodiment is not limitation of the present invention, those of ordinary skill in the art according to these embodiment institute work energy, method, Or equivalent transformation or replacement in structure, belong within protection scope of the present invention.
As shown in figure 1, the micro-nano bubble generator of the present invention includes：Intake pump 1, blender 2, jet blower 3, gas-liquid Blending tank 4, nozzle 5.
The power that the intake pump 1 is used to need sewage to be processed to provide conveying, specifically, the intake pump 1 passes through Pipeline is connected with one end of the blender 2.So as to which sewage is admitted to the blender 2 under the drive of the intake pump 1 Middle carry out gas-liquid mixed.
The blender 2 is used for the mixing for realizing sewage and oxygen or ozone.The inside of the blender 2 is negative pressure ring Border.In one embodiment, the blender 2 is venturi mixer 2.
Specifically, one end of the blender 2 is connected by pipeline with the intake pump 1, the other end by pipeline with The jet blower 3 is connected.In order to realize the gas-liquid mixed, the blender 2 is also associated with loading line, the gas tube Conveying has purity oxygen either air or ozone in road.So as to which the loading line can either air or ozone be sent by purity oxygen Enter and be sufficiently mixed in the blender 2 with sewage.In addition, for the ease of to the gas being sent into the blender 2 Flow is controlled, and gas flowmeter 21 is additionally provided with the loading line of the blender 2.
The jet blower 3 is used to spray mixed gas-liquid mixture into gas-liquid mixed tank 4.Specifically, the spray Nozzle 3 includes the body of jet blower 3 of L-shaped and is opened in the shower nozzle of the body end of L-shaped jet blower 3.Wherein, the injection The shower nozzle of mouth 3 is stretched into the gas-liquid mixed tank 4, and the inwall of the jet blower 3 towards the gas-liquid mixed tank 4 is set.From And when gas-liquid mixture is spouting from the shower nozzle, its inwall with certain speed impacts to gas-liquid mixed tank 4 On, under effect of impact, gas-liquid mixture further disperses, and causes that gas-liquid mixture mixing is more uniform in dispersion process.It is excellent Selection of land, the jet blower 3 are set towards the roof in the inwall of the gas-liquid mixed tank 4.It is arranged such, is advantageous to increase gas-liquid The scattered stroke to fall of mixture.
The side wall of the bottom of the gas-liquid mixed tank 4 is provided with outlet 41, and the outlet 41 passes through pipeline and the nozzle 5 It is connected, so as to which the gas-liquid mixture after disperseing is entered in the nozzle 5 by the outflow of outlet 41.Wherein, it is described Injection direction of the internal diameter of nozzle 5 along the nozzle 5 is gradually reduced, and is arranged such, because the outlet 41 of nozzle 5 is smaller, gas-liquid When mixture sprays, pressure diminishes suddenly, and the gas being dissolved in water is discharged with micro-nano aperture, so as to be contained For the waste water of nano bubble.
In summary, micro-nano bubble generator of the invention is vdiverse in function, its can be used for be processed sewage air supporting, Water body is oxygenated and ozone oxidation, and has higher efficiency, fully meets the actual demand of the processing of sewage, achieve compared with Good environmental benefit.
It is obvious to a person skilled in the art that the invention is not restricted to the details of above-mentioned one exemplary embodiment, Er Qie In the case of without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.Therefore, no matter From the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, the scope of the present invention is by appended power Profit requires rather than described above limits, it is intended that all in the implication and scope of the equivalency of claim by falling Change is included in the present invention.Any reference in claim should not be considered as to the involved claim of limitation.
Moreover, it will be appreciated that although the present specification is described in terms of embodiments, not each embodiment is only wrapped Containing an independent technical scheme, this narrating mode of specification is only that those skilled in the art should for clarity Using specification as an entirety, the technical solutions in the various embodiments may also be suitably combined, forms those skilled in the art It is appreciated that other embodiment.
