Description

A kind of micro-nano bubble aeration device
Technical field
A kind of micro-nano bubble aeration device is the utility model is related to, belongs to field of environment protection equipment, specifically a kind of water Processing aerator.
Background technology
Aerator is the conventional equipment of engineering of water treatment, is mainly used to be oxygenated to aerobic biochemical pool, in general sewage Power consumption accounts for the proportion of maximum in processing engineering.The high aerator of currently used efficiency comparison is disc type micro-pore aeration and tubular type Micro-pore aeration, the bubble that they discharge is relatively small, there is 1mm or so, and the utilization rate of this device oxygen is only capable of reaching than relatively low To 20%-30%.And the fault rate of these devices is high, maintenance cost is high.
The content of the invention
The utility model provides a kind of micro-nano bubble aeration device, improves oxygen utilization rate, solves general exposure The problem of device of air fault rate is high, maintenance cost is high.
To achieve the above object, this uses following technical scheme using new:
A kind of micro-nano bubble aeration device, including water pump, ejector, dissolving, pipeline, release, aeration tank;Water pump It is connected with one end of ejector, ejector top is provided with air inlet, and the other end of ejector and one end of dissolving connect, molten gas The other end of tank is connected by pipeline with release, and release is positioned in aeration tank.
Further, described water pump is connected by pipeline with the ejector.
Further, described ejector intake method is self-priming air inlet.
Further, described self-priming gas is air or oxygen.
Further, described ejector has a check valve at air inlet.
Further, the other end of described ejector is connected by pipeline with the dissolving.
Further, there is certain pressure in described dissolving.
Further, in the dissolving under pressure effect, gas is dissolved in the water with molecular state, forms molten gas Water.
Further, described release is positioned over the bottom position of the aeration tank.
Further, described release is multiple and is in branched arrangement.
To described micro-nano bubble aeration device, including following steps:
During operation, sewage is pumped into ejector by water pump with higher speed, and negative pressure, extraneous gas are formed in ejector It is inhaled under pressure through check valve in ejector, forms water jets, then water jets enters the dissolving of certain pressure In, in dissolving in the presence of pressure, gas is dissolved in the water with molecular state, forms dissolved air water, and dissolved air water passes through pipeline The release being positioned in aeration tank is reached, dissolved air water is discharged by release decompression, and the gas molecule dissolved in water is gathered into Tens nanometers to hundreds of nanometers big micro-bubbles.The bubble of micro/nano level is compared with millimetre-sized bubble, same volume gas phase ratio, Surface area increases thousands of times, and the bubble smaller residence time in water is longer, and therefore, the utilization rate of oxygen obtains greatly Improve, utilization rate can reach 60%--90%.Used release is the various ripe releases of in the market, such as the molten gas of TJ types Release, TY types dissolved air release, TS type dissolved air releases etc., the life-span is all longer at present.
The utility model has advantages below relative to prior art:
(1) the utility model greatly improves the utilization rate of oxygen;
(2) the utility model solves the problems, such as that fault rate is high, maintenance cost is high.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, drawings in the following description are these Some embodiments of utility model, for those of ordinary skill in the art, on the premise of not paying creative work, also Other accompanying drawings can be obtained according to these accompanying drawings.
Fig. 1 is the micro-nano bubble aeration schematic device of the utility model
In figure:1st, water pump, 2, ejector, 3, check valve, 4, air entry, 5, Gas dissolving pipe, 6, pipeline, 7, release, 8, expose Gas pond
Embodiment
It is noted that described further below is all exemplary, it is intended to provides further instruction to the application.It is unless another Indicate, all technologies used herein and scientific terminology are with usual with the application person of an ordinary skill in the technical field The identical meanings of understanding.
It should be noted that term used herein above is merely to describe embodiment, and be not intended to restricted root According to the illustrative embodiments of the application.As used herein, unless the context clearly indicates otherwise, otherwise singulative It is also intended to include plural form, additionally, it should be understood that, when in this manual using term "comprising" and/or " bag Include " when, it indicates existing characteristics, step, operation, device, component and/or combinations thereof.
A kind of micro-nano bubble aeration device as shown in Figure 1, including water pump, ejector, dissolving, pipeline, release, Aeration tank;Water pump is connected by one end of pipeline and ejector, and ejector top is provided with air inlet, and intake method is from inspiration Gas.The other end of ejector is connected by one end of pipeline and dissolving, and the other end of dissolving is connected by pipeline and release Connect, release is positioned in aeration tank.
Ejector has a check valve at air inlet, to prevent gas backstreaming, ensures possess certain pressure in ejector The input jet water into dissolving.
There is certain pressure in dissolving, gas is dissolved in the water with molecular state, form dissolved air water.
Release is positioned over the bottom position of aeration tank, caused bubble is fully absorbed by aerobic microbiological.
To reach more preferable effect, system availability is improved, is placed in using multiple releases in aeration tank, and multiple releases Device is in branched arrangement.
In Fig. 1, micro-nano bubble aeration device is connected successively by water pump 1, ejector 2, dissolving 5, pipeline 6, release 7 Connect.
