The specific embodiment
1-8 in conjunction with the accompanying drawings, the present invention can get the best understanding, and parts same among each figure use same label.
Fig. 1,1a show the local flow chart and the partial sectional view of one of first embodiment device 10, and it can be with one or two gases or fluent material (below be referred to as " injection material ") diffusion or emulsification in another gas or fluent material (below be referred to as " material of main part ").Material of main part can be the solid material under the normal condition, and it is heated or processed into the state of a kind of liquid or gas in diffusion/emulsion process.
A rotor 12 comprises the hollow cylinder of a general closed at both ends.Axle 14 and import 16 are connected to the end of rotor 12.First injection material can enter into the inside of rotor 12 by import 16.Axle 14 is connected on the motor 18 the speed rotary rotor of motor to require.Rotor 12 has a plurality of systems through hole 22 thereon, with bigger detailed view this through hole has been shown out in Fig. 1 a.In a preferred embodiment, each through hole 22 has the bigger perforate 26 of a narrow aperture 24 and.The sidewall 28 of perforate 26 can adopt different shape, comprises linear (as shown in Figure 4), bending shape (as shown in Figure 1) or shaped form.
When operation, diffuser is accepted material of main part by import 37.In a preferred embodiment, the material of main part of pump 42 inspiration pump suction sides is so that material of main part is by being in the passage under the low pressure.Be introduced on the material of main part by through hole 22, the first and second injection materials.Place, source at injection material can be with its pressurization to prevent that material of main part from passing through through hole 22.
Import is divided into import 16 and 36 among the embodiment shown in Fig. 1 for diffusion material.This layout makes two kinds of different injection materials be introduced in the material of main part.Also can select a kind of injection material is incorporated in two imports.
In test, the embodiment shown in Fig. 1 has shown the high level diffusion that enters the injection material in the material of main part.As the test of injection material, water, reached the level of 400% dissolved oxygen in water with oxygen as material of main part, and the sustainable a few days of level of the oxygen that increases.
The reason of efficient and lasting diffusion is considered to describe microbubble because microbubble is arranged below in conjunction with Fig. 2 a-2c.
When a material flows through a smooth surface, be equivalent to set up a laminar flow, the thin boundary layer of this laminar flow is static or flows very slowly, because between fluid that flows and static surface surface tension is arranged.Yet through hole 22 has destroyed this laminar flow, and makes this material be compressed and reduce pressure.If the pressure in decompression process is enough low, in this material, will form bubble (cavitation bubbles).Cavitation bubbles forms a kind of rotational flow mode 46, as same cyclone, because the low pressure of regional area is inhaled into material of main part and injection material, shown in Fig. 2 a.When the cavitation bubbles explosion time, extra high pressure has appearred.When the through hole of two alignment communicates mutually, exciting (shock wave) appears, produce very big energy.The energy relevant with bubble and exciting mixes injection material and material of main part on extra high degree, perhaps on molecular level.
The number of openings that the tangent line speed of rotor 12 and every circle meet has determined the frequency of device work.Have been found that under ultrasonic frequency, to be operated in many purposes and possess beneficial effect.It is believed that this device is operated under hyperacoustic frequency range, maximum exciting impact energy be provided, change fluid molecule in conjunction with the angle, this just make fluid can carry increase, irretentive injection material generally speaking.The frequency of diffuser work has obviously influenced the level of diffusion, has caused injection material last much longer in material of main part.
In some purposes, for example may wish under the situation that water purifies that a specific frequency or a plurality of frequency decompose certain complicated molecule.Under this purposes, can be with a plurality of excited frequencies with labyrinth, for example VOC (VOC, volatile organiccompounds) is broken into little minor structure.Ozone can be used as a kind of of injection material, with this kernel texture of efficient oxidation.
Fig. 3 shows the rotor 12 of this diffuser and the decomposition view of stator 30, can obtain a plurality of frequencies under a velocity of rotation.In Fig. 3, on the circumference of rotor 12, be provided with the through hole 50 (being expressed as 50a, 50b and 50c) of three row's circumferencial directions of through hole 22.Have varying number, even through hole on circumference at interval on each ring.In the same way, stator 30 will be provided with the through hole 52 (being expressed as 52a, 52b and 52c) of three row's circumferencial directions.In order to ensure have only a pair of through hole to overlap on corresponding row at every turn, the quantity of through hole 22 among certain row 52 on stator 30 can more than the quantity of through hole 22 among the row 50 corresponding on the rotor 12 (perhaps few).For example, if a row 50a has 20 the evenly through holes 20 of interval around rotor 12 circumference, a row 52 may have 21 evenly at interval at stator 30 circumference through hole on every side so.
When 12 relative stator 30 of the rotor among Fig. 3 are rotated, each row will form the exciting of different frequency.By the different frequency of suitable selection,, form a wide frequency spectrum with superposition and different interference modes occurring.In many purposes, wherein unknown impurity need be decomposed and oxidation in bulk liquid, and this frequency spectrum has beneficial effect.
Fig. 4 shows the cross sectional side view of an embodiment of stator 30.For undersized stator, perhaps form perforate 26 and have any problem in the inboard of stator 30.An inner sleeve 54 and an outer tube 56 have been used among the embodiment of Fig. 4.Can bore perforate 26 from the outside of inner sleeve 54.To each perforate 26 of inner sleeve 54, on outer tube 56, get out the aperture 24 of corresponding alignment.Then inner sleeve 54 is placed and is fixed in the outer tube 56, to form stator 30.Also can use other method, for example stator 30 is made in casting.

Fig. 5 a shows the cross sectional side view of an embodiment, and its rotor 12 and stator 30 are plate-likes.Fig. 5 b shows the top view of disc-like rotor 12.Stator is fabricated in the above and below of rotor 12.The through hole that stator 12 and rotor 30 have a plurality of the sort of forms described in conjunction with Figure 1, they meet when rotor 12 is driven by motor.As before, for every row 52, in order to prevent to be excited at the same time on two through holes in a row, stator 30 is Duoed or few one than the quantity of through hole among the row 50 corresponding on the rotor 12.Through hole 22 can be a shape same as shown in Figure 1.A hollow shaft is as the import 16 that first injection material is led to disc-like rotor inside.Equally, second injection material is accepted in the zone between stator 30 and shell 34 35.When material of main part flow in the passage 32 between rotor 12 and stator 30, it was subjected to the effect that through hole 22 places generate eddy current, makes first and second materials spread material of main part.The material of main part that is injected into leads to outlet 40.
Fig. 5 b shows the top view of rotor 12.As can be seen, a plurality of through holes constitute the concentric arrays of openings on the rotor 12.If desired, each row can produce exciting under different frequencies.In a preferred embodiment, through hole 22 will be formed on the top and the bottom of rotor 12.On stator 30, will form corresponding through hole in the above and below of these through holes.
Fig. 6 shows the profile of one embodiment of the present of invention, and its rotor 12 has taper shape.Stator 12 and rotor 30 are provided with a plurality of through holes of the sort of form described in conjunction with Figure 1, and these through holes meet when rotor 12 is driven by motor.Except the through hole around rotor 12 circumference, also can be provided with through hole in conical bottom, in the bottom of a part of stator 30, be provided with corresponding through hole.As before, for each row, in order to prevent to be excited at the same time on two through holes 22 in a row, stator 30 is Duoed than the through hole on the rotor 12 or few one.A hollow shaft is as the import 16 that first injection material is led to the disc-like rotor inboard.Equally, second injection material is accepted in the zone between stator 30 and shell 34 35.When material of main part flowed between rotor 12 and stator 30, it was subjected to the effect that through hole 22 places generate eddy current, makes first and second materials spread material of main part.The material of main part that is injected into leads to outlet 40.
In the embodiment of Fig. 5 a-b and 6, because the arrangement of through hole 22 can be formed on the diameter that increases gradually, so generate a plurality of frequencies easily.Should be noted that, can adopt many shapes, comprise with hemispherical and sphere and realize rotor 12 and stator 30.
Diffuser described herein can be used in many purposes.Best bore size (aperture 24 and perforate 26), width, rotating speed and the rotor/stator diameter of passage 32 depend on the purposes of this device.
As mentioned above, diffuser can be as oxygenation in water.In this embodiment, air or oxygen are as first and second injection materials.Air/oxygen is diffused in the sort of waste water described in conjunction with Figure 1 (perhaps other needs the water of oxidation).Have been found that diffuser can make oxygen be increased to about 400% dissolved oxygen, can produce bigger concentration when to the parameter optimization under this purposes.In test, municipal sewage under the environment temperature of about 20 five gallon bottles (reading of initial dissolution oxygen is 84.4%) is passed through this device, obtain 390% dissolved oxygen content after five minutes, it is four hours that the oxygen concentration levels that increases is maintained at more than 300% dissolved oxygen, and the dissolved oxygen more than 200% is a nineteen hour.After three days, the concentration of dissolved oxygen maintains more than 134%.In these trials, adopt the frequency of 169kHz.The size of through hole, aperture 24 are 0.030 inch, and perforate is 0.25 inch (epitrochanterian perforate 26 has hypotenuse).Cold temperature can obviously increase the level and the continuation of oxygen.
Remain wastewater treatment, or in the bioremediation to other toxic material, oxygen can be used as a kind of injection material, ozone can be used as another injection material.In this case, ozone will be used for the oxidation of structure harmful in the material of main part, for example VOC and detrimental microorganisms.Also have, as mentioned above, use a cover frequency (arrangement by through hole in rotor 12 and the stator 30 decides) that a kind of mode of destroying interference is provided, many labyrinths are resolved into little minor structure.If this processing method is used for the oxidation of a kind of single, known harmful substance, may use a kind of single frequency, and this frequency is known to successfully decomposing this structure.Otherwise, also can use a cover frequency, this frequency causes a kind of structure conflicting mode, and two kinds or more compound are aggregated into a kind of more complicated and material of macrostructure more.
In order to produce drinking water, ozone is used as first and second injection materials and decomposes and oxidize contaminants.
In conjunction with a large amount of purposes, for example municipal wastewater is corrected, and the operation of this diffuser has been discussed, but it can also be used for domestic use, for example purifying of drinking water machine, swimming pool and crawl.
This diffuser can also be used for other purposes, and the diffusion in other liquid of one of them gas or liquid changes the characteristic of material of main part.The example of this purposes comprises, makes milk evenly or make oil evenly.Other purposes is included in fuel combination and raise the efficiency the gas/liquid aspect, realizes higher fuel economy.
Fig. 7 a-b shows a plurality of optional embodiments of rotor 12 and stator 30.In Fig. 7 a, " stator " 30 also rotates; In this case, excited frequency will depend on the speed that relatively rotates between rotor 12 and the stator 30.In Fig. 7 b, in rotor 12 and the stator 30 one does not allow injection material pass through this device (in Fig. 7 b, having only rotor to pass through an injection material); This device that does not allow injection material pass through has the cavity 58 that replaces through hole 22, produces turbulent flow.Cavity 58 is made to be similar to is not with the perforate 26 of aperture 24 together.
In Fig. 7 c, the aperture 24 of that injection material passes through, rotor 12 or stator 30 is set near the perforate 26, rather than as the embodiment of front, is located in the perforate 26.Should be noted that the main purpose of perforate 26 is to disturb along rotor 12 and stator laminar flow 30 surfaces, material of main part.The compression of material of main part and thin (decompression) cause that microbubble, microbubble provide the high diffusion that is caused by this device.In the process of decompression, in material of main part, form bubble (cavitation bubbles).Cavitation bubbles is grown up and shrink (perhaps blast) under the contention effect that excited frequency applies.When material of main part flows through passage 32, cavitation bubbles blast produce power, this energy helps injection material is highly diffused in the material of main part.Therefore, reach a bit as long as injection material and material of main part mix, wherein bubble occurs with the shock wave that causes, above-described diffusion will produce.
Fig. 7 d shows an embodiment, and wherein tentatively being blended in outside the passage 32 between material of main part and the one or more injection material carried out.In this embodiment, adopt Mazzie diffuser 60 (perhaps other device) to realize the initial mixing of injection material and material of main part.Mixture is imported in the passage 32 between rotor 12 and the stator 30, stands compression/rarefaction cycles discussed above here, cause occurring bubble in the mixture, and mixture is subjected to a shock wave frequency role.
Also have, can realize the generation of bubble and shock wave with the structure that is different from the perforate 26 shown in the top embodiment.As noted above, perforate 26 is for surface disturbance, and it hinders the laminar flow of material of main part along passage 32 walls.In Fig. 7 e, a projection, for example projection 62 can replace perforate 26 or cooperate surface disturbance of formation with perforate 26.Can also use the shape outside the circle.Shown in Fig. 7 f, can in rotor 12 and/or stator 30, form groove (perhaps projection) 64, to produce bubble and shock wave.
As noted above, not all purposes all needs to generate a shock wave under the CF, perhaps therefrom obtains beneficial effect.Therefore, rotor 12 and stator 30 can be provided with a plurality of perforates 26 (perhaps other surface disturbance) that white noise rather than some CFs can occur.The structure that is used for forming bubble does not need unification; On rotor 12 and stator 30, form an abundant coarse surface and also will cause bubble.In addition, shown in Fig. 7 g, need on the surface of rotor 12 and stator 30, all not form bubble; Yet in most of the cases, if all be used on two surfaces, the operation of device 10 will be more effective.
Fig. 7 h shows an embodiment, causes that wherein the mobile of bubble is to be provided by material of main part (also can select the injection material of being pulled into for use), rather than provide by the relative motion of rotor 12 and stator 30.In the embodiment of Fig. 7 h, between two static mutually walls 66, form passage 32, one or two walls have towards the surface disturbance of passage 32.Make material of main part under high speed, be driven through this passage with a pump or other device, to form high velocity stream.By aperture 24 or by material of main part and injection material are mixed outside passage, one or more injection materials are injected in the passage.The relative wall 66 of material of main part causes above-mentioned microbubble and exciting at a high speed.
As an example, one or more walls 66 can be fine mesh, and injection material flow in the material of main part in the passage 32 by this mesh and mixes with it.When the material of main part high velocity stream is crossed this mesh, the surface disturbance in the mesh will cause microbubble and exciting.Excited frequency will depend on the closeness of mesh and the speed of material of main part.Equally, at the microbubble place, injection material will be diffused in the material of main part on molecular level.
Fig. 8 a, 8b show an alternative embodiment of the invention, and wherein rotatable parts 70 are arranged in the conduit 70, and are rotated by motor 73.Adopt Mazzie diffuser 74 or other device, in the upstream conduit 72 of rotatable parts 70, material of main part and injection material are mixed.On the surface of rotatable parts 70, be provided with one or more surface disturbance, like this, the rotation of rotatable parts 70 produces microbubble discussed above, thereby causes high diffusion in material.For above-mentioned purpose, the mode of the shape of impeller blade and surface disturbance 76 can form microbubble and exciting under the frequency of hope.In addition, the shape of tumbler can make material be inhaled into to pass through conduit.
Compared with prior art, the invention provides many tangible beneficial effects.The first, the microbubble that this device produces makes and diffuses out on the present molecular level, thus increased the quantity of the injection material that will keep by material of main part, and prolonged lasting diffusion.The second, microbubble and shock wave can produce by fairly simple mechanical device.The 3rd, the impact wave frequency or a plurality of frequency that are produced by this device can be used for many purposes, perhaps decompose labyrinth or help composite structure.The 4th, bubble and shock wave can evenly produce in whole material so that continue diffusion.
Although detailed description of the present invention is carried out according to illustrative embodiment, those skilled in the art can do various modifications to these embodiment and other available embodiment.Present invention resides in any modification and interchangeable embodiment in the desired scope.
