Preferred embodiment of the present utility model is, described rotary compression chamber 2 is round table-like, and air-bubble outlet 5 is arranged on the roundlet of round platform, and this is optimal way, is not limited to this mode.
Operation principle of the present utility model is as follows:
As shown in the figure, gas-liquid mixed liquid with pressure enters with tangent line from the air water import with pressure of high-pressure air-water mixing chamber, do circumference along high-pressure air-water mixing chamber inwall and rotate into the rotary compression chamber, after the rotary compression cavity wall is realized accelerating and is pressurizeed, after rotating to the summit with the high speed vorticity, spray with the high speed vortex from the air-bubble outlet on summit, high-voltage high-speed vortex gas-liquid mixed liquid is ejected in the environment of outside liquid, outside liquid is produced ionization, the effects such as dissolving, in the vortex process, the bubble that mixes in the liquid is accelerated, and the propelling along with accelerator, liquid internal pressure increases gradually, and bubble is compressed by the limit, forms the charged boundary of high energy and sees the size micro-bubble.

After adopting the utility model, gas-liquid mixed liquid is input in the high-pressure air-water mixing chamber with certain pressure and flow, enter again the rotary compression chamber, liquid is done eddying motion along the rotary compression cavity wall under guide functions, export from the air-bubble outlet in rotary compression chamber at last, under the condition that keeps constant pressure and flow, because rotary compression chamber diameter progressively dwindles, the liquid vortex rotating speed progressively increases, liquid internal pressure increases along with the liquid rotating speed and progressively strengthens, the linear velocity of liquid motion also increases thereupon, when arriving the air-bubble outlet, the rotating speed of liquid, it is maximum that pressure and linear velocity reach, and the high-voltage high-speed that has formed liquid at many magnetic field of revolution cavity delivery outlet sprays.
The utility model also has ionization: be provided with the magnetic sheet layer on the rotary compression cavity wall, form many magnetic fields, because the bubble in the gas-liquid mixed liquid is through too much magnetic field, the bubble that therefore forms makes bubble form the ion air mass with the ion that ionization produces.After these ion air mass are ejected in the liquid with higher linear velocity, liquid strong machine cuts ionization and ionic discharge ionisation effect have been produced, make and produced a large amount of negative ions in the liquid and surrounded bubble, under the effect of these ions, bubble surface tension force progressively increases, make the diameter of bubble more and more less, and progressively be dissolved in the water along with the dissolving of ion, and this ionization power and surface tension be all or part of to have resisted the buoyancy of liquid to Bubble formation, making bubble no longer is that straight line rises in liquid, but stops for a long time or thoroughly be dissolved in the liquid.
The utility model also has the intermolecular energy effect: all have intermolecular active force between any molecule, be called intermolecular energy.Contain before the alveolate aqueous solution injection, bubble is compressed to minimum because of the effect of pressure, bubble diameter is compressed to micron or Nano grade, intermolecular energy is accumulated and is reached the highest, after bubble broke or dissolves, the motion of gas molecule Free Thermal strengthened, and can join at any time in the hydrone covalent bond becomes dissolved oxygen, the covalent bond that other materials and hydrone form that also can rupture at any time, its material of redox.
The utility model produces Explosive Energy because of the effect of damaging by pressure: in water body, because micro-nano bubble is subject to the physics (compression and expansion that the flow process of water produces of water, bumpy flow etc.) after the effect, can because of moment adiabatic compression produce the limit reacting field of hyperpressure hyperthermal, this limit Reaction field energy and on every side water effect generate the free radical of efficient OH etc., and the free radical molecule is very unsettled active material, in order to capture electronics in the hope of the ionization equilibrium of self from other molecule, extremely strong oxidability can be given play to, the harmful chemical of solving problem and decomposing can be divided.
After oxygen bubbles enters in the water, because of the bubble internal pressure higher, cause walls to have higher tension force, bumping or other conditions cause bubble to break or when dissolving, the tension force effect of walls will discharge huge explosion energy---ultrasonic energy, this ultrasonic wave has very strong bactericidal action, can produce a large amount of anions, simultaneously can impel oxygen molecule to be dissolved in water, destroying pollutant is connected with the covalent bond of water, the chemical bond that also can destroy pollutant inside connects, and finishes the oxidative degradation pollutant.
The sterilization process of micro-nano oxygen big gun comprises attraction and kills two processes, the bacterium and virus of this charged bubble in can adsorbed water body, along with breaking of bubble, the superhigh-temperature and-pressure that excites a large amount of free radicals and break and produce kills the bacterial virus of absorption.This process has more practical meaning in field of environmental decontamination.
Microbubble self has stronger surface tension, under the effect of peripheral hydraulic pressure, further constantly compressed again when injecting in the water at a high speed, and the larger superfine bubble of formation gas-liquid critical table area, being retracted at last to a certain degree then disappears is dissolved in the water body, and this is that it has powerful deliquescent reason place.And in the process of shrinking, along with dwindling of bubble, the air pressure in the bubble is inversely rapidly raising, makes the interior gas of bubble be in the super-pressure state, and this super-pressure state is combined with the superhigh temperature effect, is the major reason place that microbubble produces the ultrasonic wave proterties.
