Specifically, the front end face of conducting element 42 and into the radial distance between dissolved air water pipeline section 41 be 6~10mm (such as
8mm), the axial distance between the front end face of conducting element 42 and the anterior cavity wall of turbulent chamber 45 is 2~4mm (such as 3mm), out microbubble
The internal diameter of 7 rear end of aquaporin-4 is 2~4mm (such as 3mm), and the width of the outer end face of cone tank is 0.5~2.5mm (such as 1.5mm),
The cone angle of cone tank is 80~100 degree (such as 90 degree), and the cone angle of tapered surface is 10~30 degree (such as 20 degree).
The low-purity oxygen plant, the bubble diameter being precipitated can be stablized at 50 μm or so, have the advantages that
1, the residence time is long in water: it is compared with Centimeter Level bubble, it, can be quick after Centimeter Level bubble generates in water body
Rise to the water surface and rupture disappearance, the residence time in water body is too short, and dissolved oxygen effect is poor, and micro-nano bubble in water on
The speed risen is slower, and the time from generating rupture can achieve tens seconds or even a few minutes.
2, itself pressurization dissolution: there are the contact interface of gas-liquid two-phase, the presence of gas-liquid interface makes the bubble surface in water
Surface tension effects of the bubble by water are obtained, surface tension effects can compress the gas in bubble, so that gas is easier to
It is dissolved into water, the surface tension that micro-nano bubble is subject to is much larger than Centimeter Level bubble, it can be gradually reduced, final completely molten
Solution.
3, interface zeta potential is high: when micro-nano bubble is shunk in water, electrically charged ion is able to carry out on bubble interface
Enrichment method, shows as dramatically increasing for zeta potential, can produce very high zeta potential value, zeta potential value before bubbles burst
It is an important factor for influencing bubble surface absorption property, the size of value can generate the absorption property of micro-nano bubble interface
Significantly influence.
4, generate hydroxyl radical free radical: micro-nano bubble is when shrinking, since the charge density of electric double layer increases rapidly, bubble
When rupture, the acute variation that gas-liquid interface disappears discharges the energy of the negative ions savings of high concentration on interface, can swash at this time
Hair generates a large amount of hydroxyl radical free radical.
These advantages of micro-nano bubble, make it in river aeration, can effectively administer black and odorous water, purify water.
Arrow indicates aqueous vapor transmission direction in Fig. 1, and "front", "rear", " tapered " in the application, " gradually wealthy " are along water flow
The restriction that transmission direction carries out.
In conclusion low-purity oxygen plant provided by the invention, goes out microbubble technology in conjunction with molten air elutriation and bleed manufactures bubble skill
Art is intake, air inlet by water inlet air pipe before entering gas-liquid mixing pump, air water is made to be sufficiently mixed dissolution in equipment,
Dissolved air water is formed, microbubble most is precipitated through micro bubble releasing device afterwards, the device structure is simple, equipment requirement is low, solves manufacture
Process and operation are all more troublesome, require high, manufactured Air Bubble Size is uneven, cost is high to ask bubble generator
Topic, the practicality is more preferable, and the microbubble of precipitation can effectively administer black and odorous water, purify water in river aeration.
