Embodiment:
A preparation method for micro-nano air-bubble, is characterized in that comprising and carries out following steps successively:
(1) apply pressure to gas-liquid mixture fluid, make its high speed rotating, imported by gas-liquid mixture fluid in elliptical vessel, gas-liquid mixture fluid forms negative pressure axle at the middle part of elliptical vessel;

(3) jet orifice of the gas-liquid mixture fluid of high speed rotating from elliptical vessel two ends is sprayed, namely produce micro-nano bubble.
The principle of work of preparation method provided by the invention is: when the gas-liquid mixture fluid of high speed rotating sprays from the jet orifice at elliptical vessel two ends, gas-liquid mixture fluid has the effect that is multiplied on the speed of rotation of superelevation and the mechanics of gas-liquid density ratio (1: 1000), shearing powerful at a high speed and high-frequency pressure variation is produced between gas-to-liquid contact interface, form artificial extreme condition, generate a large amount of micron under these conditions, have while nano grade air bubbles and smash polymerizable molecular group, form the effect of subset active water, and the ionization of small portion water molecules can be decomposed, active oxygen can be produced in micro-nano bubble space, oxonium ion, the radical ion such as hydrogen ion and hydroxide ion, especially hydroxyl free radical has the reduction potential of superelevation, there is the pollutent that superpower oxidation effectiveness also can be difficult under normal condition in water of decomposition decompose, realize the purification of water quality.The dissolution rate that micro-nano gas ducks in drink is more than 85%, dissolved oxygen concentration can reach capacity more than concentration, and micro-nano bubble remains in water in the mode of bubble long-time (lift velocity 6cm/ minute), constantly active oxygen can be supplemented in water along with the consumption of dissolved oxygen, for the microorganism of disposing of sewage provides sufficient active oxygen, strong oxidizing property ionic group, and ensure that the reaction times of active oxygen abundance, by the detergent power of micro-nano bubble treated water far away higher than the self-purification capacity under natural condition.
The characteristic of micro-nano bubble, comprises following aspect:
1. specific surface area is large
The volume of bubble and the relation of surface-area can pass through formulate.The cubature formula of bubble is V=4 π/3r3, and the surface-area formula of bubble is A=4 π r2, and two formula merge can obtain A=3V/r, namely V total=nA=3V is total/r.That is, when cumulative volume constant (V is constant), the diameter of the surface-area that bubble is total and single isolated bubbles is inversely proportional to.According to formula, the bubble of 10 microns compares with the bubble phase of 1 millimeter, and under certain volume, the former specific surface area is 100 times of the latter in theory.The contact area of empty G&W just adds 100 times, and various speed of response too increases 100 times.
2. lift velocity is slow
According to Stokes'theorem, square being directly proportional of the lift velocity that gas ducks in drink and bubble diameter.The lift velocity of the less then bubble of bubble diameter is slower.From the graph of a relation of bobble rise velocity and bubble diameter, the gas of the bubble diameter 1mm speed risen of ducking in drink is 6m/min, and the lift velocity that the gas of diameter 10 μm ducks in drink is 3mm/min, and the latter is the former 1/2000.If consider the increase of specific surface area, the dissolving power of micro-nano bubble increases by 200,000 times than general air.
3. self supercharging is dissolved
Bubble surrounding in water has liquid-gas interface, and the existence of liquid-gas interface makes bubble can be subject to the capillary effect of water.For the bubble with globular interface, the gas in surface-tension energy compressed bubble, thus make gas dissolving in more bubble in water.According to Young-Laplace equation, the numerical value that Δ P=2 σ/r, Δ P representative pressure rises, σ represents surface tension, and r represents bubble radius.Diameter can be ignored the bubble pressure of more than 0.1mm is very little, and the micro-bubble of diameter 10 μm can be subject to 0.3 atmospheric pressure, and the bubble of diameter 1 μm can by up to 3 atmospheric pressure.The dissolving that micro-nano gas ducks in drink is a diminishing process of bubble, the rising of pressure can increase the dissolution rate of gas, along with the increase of specific surface area, it is more and more faster that the speed that bubble reduces can become, thus be finally dissolved in water, bubble is about to pressure when disappearing in theory is infinitely great.
4. surface charging
H+ and OH-that pure water solution is generated by water molecules and a small amount of ionization forms, the gas liquid-gas interface formed that ducks in drink has the feature of acceptant H+ and OH-, and cation ratio negatively charged ion more easily leaves liquid-gas interface usually, and make interface often with negative charge.Band powers on the gegenion, the particularly gegenion of high price that the surface of lotus is generally tended in adsorption medium, thus forms stable electrostatic double layer.The potential difference that the surface charge of microbubble produces often utilizes zeta-potential to characterize, and zeta-potential is the important factor determining bubble interfacial adsorption performance.When micro-nano gas ducks in drink contraction, charge ion obtains rapid concentration enrichment on very narrow and small bubble interface, shows as the remarkable increase of zeta-potential, before bubbles burst, can form very high zeta-potential value in interface.
5. produce a large amount of free radical
Microbubbles rupture moment, due to the acute variation that liquid-gas interface disappears, the chemical energy of savings discharges by the high concentration ion that interface is gathered quickly, now can excite and produce a large amount of hydroxyl radical free radicals.Hydroxyl radical free radical has the redox potential of superelevation, is difficult to the pollutent of oxygenolysis as phenol etc., realizes the cleaning action to water quality in its superpower oxygenizement degradable water produced under normal condition.
6. mass-transfer efficiency is high
Gas-liquid mass transfer is the rate-limiting step of many chemistry and biochemical process.Research shows, gas-liquid mass transfer speed and efficiency and bubble diameter are inversely proportional to, and microbubble diameter is minimum, in mass transfer process, have clear superiority than traditional bubble.When bubble diameter is less, the impact of surface tension on Bubble Characteristics of microbubble interface shows comparatively remarkable.At this moment surface tension creates compressive action to internal gas, makes microbubble constantly shrink and show self pressurized effect in uphill process.See theoretically, along with infinitely reducing of bubble diameter, the specific surface area at bubble interface also infinitely increases thereupon, finally because self pressurized effect can cause air pressure inside to increase to infinity.Therefore, microbubble is in its volumetric shrinkage process, because specific surface area and air pressure inside ground constantly increase, more gas is made to be dissolved in water through bubble interface, and along with the capillary action effect of reduction of bubble diameter also more and more obvious, final internal pressure reaches certain ultimate value and causes bubble interfacial rupture to disappear.Therefore, this self supercharging performance of microbubble in contraction process, liquid-gas interface place mass-transfer efficiency can be made to obtain strengthen continuously, even and if this characteristic makes microbubble when gas content reaches supersaturated condition in water body, the mass transfer process of gas still can be proceeded and keeps efficient mass-transfer efficiency.
7. gas dissolving rate is high
Micro-nano bubble has the advantages that lift velocity is slow, self supercharging is dissolved, micro-nano bubble is made progressively to dwindle into nano level in uphill process slowly, finally cut down to bury in oblivion and dissolve in water, thus greatly can improve gas (air, oxygen, ozone, the carbonic acid gas etc.) solubleness in water.For common blister, often there is saturation solubility by the impact of environmental stress and restriction in the solubleness of gas.Under standard environment, the solubleness of gas is difficult to reach capacity more than solubleness.And micro-nano bubble is because the pressure of its inside is higher than environmental stress, make to be that the dissolved gas supersaturation dissolution conditions that assumed conditions calculates is broken with normal atmosphere.
