Shown in profile and perspective internal view etc. described above, microvesicle generates nozzle 1 by carrying out group to two components
Close to be formed.Specifically, microvesicle generation nozzle 1 possesses：The upstream side structure as first component positioned at the upstream side of primary flow path
Part 2 and the downstream side member 3 as second component positioned at the downstream of primary flow path.Upstream side member 2 and downstream structure
Part 3 can be formed using metal as such as stainless steel, other materials.
Fig. 9 is the inside of the microvesicle generation nozzle 1 for the state after decomposing upstream side member 2 and downstream side member 3 that represents
Perspective elevation.From Fig. 9, above-mentioned profile etc.：The connecting portion of upstream side member 2 and downstream side member 3 has upstream
The internal diameter of side member 2 and the external diameter identical part of downstream side member 3, by the way that downstream side member 3 is inserted into upstream side member 2
Inside, both are connected.Specifically, the corresponding part of the internal diameter of the end of downstream side of upstream side member 2 and downstream side member 3
External diameter it is identical.
In addition, downstream side member 3 has its external diameter part smaller than the internal diameter of upstream side member 2, by upstream side member 2
In the state of being combined with downstream side member 3, gas suction chamber 4 is formed therebetween.Specifically, downstream side member 3
Upstream-side-end external diameter it is smaller than the internal diameter of the corresponding part of upstream side member 2.Gas suction chamber 4 is provided at microvesicle generation spray
The space of ring-type in mouth 1.The air attracted imports into primary flow path via gas suction chamber 4 around primary flow path.
In addition, from profilograph etc.：The size of the diameter of primary flow path changes in microvesicle generation nozzle 1.Need
It is bright, even if the size variation of diameter, the center of the axle of the flow direction of primary flow path alternatively linearly shape.
The upstream side member 2 of microvesicle generation nozzle 1 is included from the feed pipe 5 of the upstream side for being connected to primary flow path (in Fig. 1 only
Show internal diameter) it is supplied to the water route 21 of water.Water route 21 is formed as the columned space of its diameter fixation.
Then, upstream side member 2 has the reducing diameter part 22 that its diameter tapers into the downstream of water route 21.That is, contract
Footpath portion 22 turns into the space of circular cone shape.Primary flow path turns into so-called Venturi tube, in reducing diameter part 22, the water that passes through from inside
Flow velocity rise, and pressure decline.
Moreover, upstream side member 2 has the constriction of the cylindrical space minimum as internal diameter in the downstream of reducing diameter part 22
Portion 23.The size of the internal diameter of necking section 23 is 0.1~0.4 times of the internal diameter of water route 21 or so.In the downstream of necking section 23
Possesses the prominent shape pipe 24 that pipe protrudes downstream.The flow velocity of the water risen in reducing diameter part 22 becomes more in necking section 23
It hurry up.In addition, in necking section 23, pressure is decreased up to close to vacuum according to flow velocity.In addition, when pressure drop is low to less than equal to full
During with vapour pressure, using the nuclei of bubbles that is present in water as core, free by the air of dissolving produces cavitation bubble
(Cavitation bubble)。
In addition, upstream side member 2 has supply road 25 in the position connected with above-mentioned gas suction chamber 4.Air is via confession
Tracheae 6 (internal diameter is merely illustrated in Fig. 1) supply extremely supply road 25.Supply road 25 is connected via air supply pipe 6 with such as extraneous air.
In addition it is also possible to the adjustment valve 7 for being provided for adjusting the influx of extraneous air in air supply pipe 6 (shows accompanying drawing mark in Fig. 1
Note).
In addition, the end of the downstream side member 3 of microvesicle generation nozzle 1 at upstream side has suction room 31.Suck room 31
Diameter tapered into towards downstream.That is, suction room 31 could also say that the space of circular cone shape.In addition, by upstream side
In the state of component 2 and downstream side member 3 connect, the prominent shape pipe 24 of upstream side member 2 is projected in suction room 31.In addition,
Multiple air vents 32 for being used to supply air, suction room 31 and gas suction chamber 4 are provided between suction room 31 and gas suction chamber 4
Connection.In room 31 is sucked, negative pressure is produced by Venturi effect, attracts extraneous air from air vent 32.
From profilograph etc.：Air vent 32 tilts towards the downstream of primary flow path.In other words, air vent 32 from suction
31 connecting portion of entering the room is slightly tilted and extended to the upstream side of primary flow path.That is, air vent 32 towards not with the water of primary flow path
Opposite direction is flowed with primary flow path to collaborate.By the inclination, situation about vertically linking with such as primary flow path and air vent 32
Compare, can more successfully carry out the interflow of water and air.In other words, the momentum of the caused current by the supply of air can be reduced
Loss.Air vent 32 and preferably 50~80 degree or so of angle formed by the central shaft of primary flow path.In addition, the cone located at suction room 31
Degree makes the interflow of water and air become smooth, and plays the speed for maintaining the current risen in reducing diameter part 22 and necking section 23
The effect of degree.In addition, prominent shape pipe 24 is projected in suction room 31, thus, the adverse current of current can be prevented.It is excellent in order to prevent adverse current
The end of downstream side of the prominent shape pipe 24 of choosing projects to the degree for the position intersected with the extended line of air vent 32.
Figure 10 is the perspective internal view of the air vent 32 in microvesicle generation nozzle 1 from front.By Figure 10, drawing in side sectional elevation
Deng knowable to：Air vent 32 is set to the extended line in its axle center and the central shaft of primary flow path staggers.Specifically, from cross section
When, each air vent 32 is located at the position of the tangent line of the inwall nearly equivalent to primary flow path.That is, when from cross section, supply
Hole 32 is set to intersect in primary flow path, and the inwall of air vent 32 and the inwall of primary flow path almost connect.But for manufacturer
Just, air vent 32 is located at actual close to the central shaft side of primary flow path than the inwall of primary flow path.Imported when with such angle
During air, air circles round and flowed in suction room 31 in the shape of a spiral.Accompany with this, the water flowed into from upstream side member 2 also exists
Circle round and flow in the shape of a spiral in suction room 31.
In addition, downstream side member 3 has the throat for the cylindrical space fixed as internal diameter in the downstream of suction room 31
(Throat)33.In throat 33, internal pressure rises compared with suck room 31, flows through the water of primary flow path and is attracted by sucking room 31
Air mixes.In addition, downstream side member 3 has diffusion (Diffuser) portion that internal diameter becomes larger in the downstream of throat 33
34.Caused eddy flow also forms whirlpool in throat 33 and diffusion part 34 in suction room 31, produces Strong shear power.Meanwhile
Collided by the cavitation bubble generated in reducing diameter part 22 and necking section 23 with the air imported from air vent 32, bubble also can
Miniaturization.As described above, from air vent 32 suck air pulverizedization and generate microvesicle.Then, the jet flow comprising microvesicle from
Diffusion part 34 sprays.
Nozzle 1 is generated according to the microvesicle of present embodiment, can reduce and supply to the momentum (flow velocity) of the current of primary flow path
Loss, and generate the high jet flow containing microvesicle of jet power.
In microvesicle generates nozzle 1, in order to which negative pressure region is set into appropriate length, it is preferably provided with necking section 23 and expands
Portion 34 is dissipated, when being not provided with them, performance reduces.In addition, when being not provided with throat 33, adverse current is produced in diffusion part 34 sometimes
Current.By the way that the ratio of reducing diameter part 22, necking section 23, air vent 32, throat 33 and diffusion part 34 is optimized, so as to work as
When the hydraulic pressure of supply is 0.3MPa, the air of 80% capacity of the energy self-priming water of microvesicle generation nozzle 1.
<Comparative example>
Figure 11 is the curve map for the result for showing schematically the pressure simulated in device.The longitudinal axis table of Figure 11 curve map
Show pressure, transverse axis represents the distance of the upstream end of the necking section 23 in distance means.The adjustment valve 7 that solid line represents to open Fig. 1 is led
The change for the pressure for (having air mode) in the case of entering air.The adjustment valve 7 that single dotted broken line represents to close Fig. 1 does not import air
In the case of (no air mode) pressure change.It should be noted that hydraulic pressure (with air the relative pressure of the water supplied
Power) it is identical.In addition, when becoming less than equal to saturated vapour pressure (Figure 11 cavitation generates pressure), start to generate cavitation bubble.
As shown in figure 11, do not import in the case of importing air and in the case of air in the suction room 31 than being imported for extraneous air
Start the generation of cavitation bubble in forward necking section 23.Therefore, the importing of the air from air vent 32 no matter is whether there is, all may be used
To say being to form the composition for generating microvesicle.
Figure 12 is to show schematically feelings that the extended line in the axle center to being set to air vent 32 and the central shaft of primary flow path stagger
The size of the hydraulic pressure of (no spiral) is carried out in the case of (having spiral) under condition and air vent 32 being located on the central shaft of primary flow path
The curve map of the result of simulation.It should be noted that the hydraulic pressure (relative pressure with air) of the water supplied is identical.It is solid
Line is the curve map for representing to use the hydraulic pressure in the case of the air vent 32 of present embodiment as shown in Figure 10.It is in addition, thin empty
Line is to represent the curve map using the hydraulic pressure in the case of the air vent 32 for not producing spiral helicine eddy flow as shown in fig. 13 that.
In Figure 13 example, air vent is set to the extended line in its axle center and intersected with the central shaft of primary flow path.Using present embodiment
In the case of air vent 32, it is contemplated that：Hydraulic pressure in necking section 23 becomes less than the saturation water steaming equal to generation cavitation bubble
Air pressure (Figure 12 cavitation generation pressure), more generates cavitation bubble.On the other hand, using air vent as shown in fig. 13 that
In the case of 32, it is contemplated that：The growing amount of cavitation bubble tails off, and at the same time the formation efficiency of microvesicle also reduces.That is, even if
The pressure of the water supplied is identical, flow velocity and insufficient rising in the case of without spiral, and cavitation life is not reached in necking section
Into pressure.
<Effect>
Figure 14 is measuring fine particles machine (the corpuscular counter HIAC for representing the downstream by being arranged on diffusion part 34
Royco) curve map of the result of particle number generated by microvesicle generation nozzle 1 is measured.The transverse axis of Figure 14 curve map represents
Driving pressure (MPa), the longitudinal axis represent the observation quantity per 1mL.In the case of driving pressure as low as 0.05MPa or so, almost
Particulate is not observed, but as long as being the driving pressure more than that, it becomes possible to observe.It should be noted that the in view of sight of device
The situation in region is surveyed, bubble of the diameter less than 4 μm is not counted, but be contemplated that and also create so-called extra small bubble
Deng.
Figure 15 is in the case of representing to carry out rotating device using the microvesicle generation nozzle 1 of embodiment and inoperative device
In the case of dissolved oxygen content curve map.The transverse axis of Figure 15 curve map represents the ratio of dissolved oxygen content, and the longitudinal axis represents the moment.
In addition, thick line be represent by microvesicle generation nozzle 1 be connected to pump and make water circulation, generation microvesicle in the case of, dissolved oxygen

Carried out for the daytime of first day of " MB operatings ".In addition, fine rule is to represent the dissolved oxygen rate in the case where not generating microvesicle
Curve map.Oxygen solubility ratio before beginning is less than 90%, even in second day, has carried out the oxygen solubility ratio in the case of device operating
Also it is high.Because microvesicle, extra small bubble are remained in water for a long time, it is therefore envisaged that the microvesicle that remaining has generated.It is in addition, real
It is high to apply the ejection efficiency of the microvesicle generation nozzle 1 of mode, also can equably be sprayed in several meter Jian Fang pond time.This experiment is
What the early winter not reduced in comparatively speaking oxygen solubility ratio implemented, but summer further reduced because temperature such as rises at the oxygen solubility ratio,
It is therefore envisaged that the availability of the present apparatus improves.
<Variation>
In the above-described embodiment, the structure that air micro-bubbles are generated in water is illustrated, but can also be to main flow
Liquid beyond road supply water.In addition it is also possible to the gas imported from supply road 25 beyond air.Sky is being imported from supply road 25
In the case of gas beyond gas, the high-pressure gas cylinder of supply road 25 with being equipped with object gas etc. is connected, rather than empty with outside
