Connection, receive by accelerate swirl-flow premixed mechanism 1 and Lai fluid-mixing.First axis exports the 212, second axial outlet 213
Cross section is circle, for being connected with diffusion eddy flow mixed organization 3.Accelerate the center of the incoming import 111 of swirl-flow premixed mechanism 1
Line is by turning to the right in the axle center 216 of chamber 21, the left side in axle center 216 or axle center 216.
Diffusion eddy flow mixed organization 3 has two, the both sides for turning to eddy flow mixed organization 2 is separately positioned on, for convection current
Body carries out axial-flow type expansion diffusion, and each diffusion eddy flow mixed organization 3 includes diffusion chamber 31, cylindrical, diffusion chamber 31
With the axial outlet 312 of axial inlet 311 and the 3rd.Any axial cross section of diffusion chamber 31 is circular, diffusion chamber 31
Axial cross section axial inlet 311 nearby along the 3rd it is axial export 312 directions have it is continuous or discrete gradual
Expand, the axial cross section of diffusion chamber 31 is axially exported near 312 vertically until the 3rd axial outlet 312 has the 3rd
Continuous or discrete gradual contraction.
The diffusion chamber 31 of above-mentioned this structure, can to by steering chamber 21 and Lai high speed rotating fluid carry out axis stream
The rotary diffusing deceleration shock mixing of formula and turbulent shear, are sheared by manufacturing the alternate strong turbulence of gas-liquid two-phase, reach generation
The purpose of bubble.Due to the change of flow channel cross-section product, after the incoming of axial-rotation enters diffusion chamber 31, speed will drop suddenly
It is low, and pressure then significantly raises；Simultaneously as relatively large space and the relatively small discharge area of diffusion chamber 31,
Cause the flow velocity on 312 sections of the 3rd axial outlet very high, but in the later half of the diffusion chamber 31 close to the 3rd axial outlet 312
Part, outlet is small, resistance is big, and sluggish and sedimentation is produced to above incoming, rotates incoming from the high speed for turning to chamber 21
Rotary impact will be produced to the latter half of fluid of diffusion chamber 31 that is deposited in of relative low speeds, its speed will significantly reduce and will
Strong rotary impact immixture and the alternate strong turbulence shearing of gas-liquid two-phase are produced, and then causes a large amount of bubbles bursts, and
The unexpected rise of pressure then will accelerate and strengthen this bubbles burst process.
The cross section of axial inlet 311 is circle, and two axial inlets 311 of two diffusion eddy flow mixed organizations 3 are distinguished
It is connected with the 212, the second axial outlet 213 of first axis outlet for turning to eddy flow mixed organization 2, each axial inlet 311

312 cross section is circle, for being connected with bubble emitting mechanism 4.
Bubble emitting mechanism 4 has two, is connected respectively with each diffusion eddy flow mixed organization 3.In the present embodiment,
Bubble emitting mechanism 4 uses throttle nozzle, it is preferred that sprays machine for daraf(reciprocal of farad) that formula, venturi type or straight pipe nozzle, bubble
Structure 4 has jet expansion 41, and the exit orifice of one or more than one is offered on the cross section of jet expansion 41.
In order to further strengthen the strong turbulence shearing to gas-liquid two-phase fluid gas part, can be mixed turning to eddy flow
Between the bubble emitting mechanism 4 for closing mechanism 2 and every side, more than one diffusion eddy flow mixed organization 3, previous diffusion are set
311 phase of axial inlet of the 312 diffusion eddy flow mixed organizations 3 adjacent with the latter of the axial outlet of the 3rd of eddy flow mixed organization 3
Connection.
Above-mentioned micro bubble generation device the gas-liquid mixture fluid of inflow is carried out successively spiral rotating accelerate mixing, to
Core type runoff axis rheology is to spinning up the multistages such as mixing, axial-flow type expansion diffusion rotary impact mixing and throttling jet mixing
Multiple dimensioned strong eddy flow turbulent shear is with mixing.In above-mentioned whole flow process, using the huge poor properties between gas-liquid two-phase away from：It is close
Degree difference and viscosity are poor, and unexpected acceleration, spiral rotating are employed to two-phase fluid, turns to rotation, rotary impact, is slowed down suddenly (prominent
So slow down the same with accelerating suddenly, be provided to the alternate strong turbulence shearing of manufacture gas-liquid two-phase, reach the mesh for generating bubble
), suddenly pressurize and outlet throttling accelerate decompression etc. physical process, purpose be provided to manufacturing speed alternate in gas-liquid two-phase
Difference and strong turbulence shearing, and then cause the multistage multiple dimensioned rupture of bubble, a large amount of required micro-nano bubbles of manufacture production.
