Detailed Description
Referring to fig. 2A and 2B, fig. 2A is a perspective view of a superfine bubble generating device 10 according to a first embodiment of the present invention, and fig. 2B is a cross-sectional view of a box cover 12, a bubble generating medium 15 and a box 14. The ultra-fine bubble generating device 10 includes a lid 12, a compressed gas source 13, a box 14, a bubble generating medium 15 and a jet 16. The cover 12 is assembled above the case 14, and a jet channel 14P is formed between the case 14 and the cover 12.
Further, the bubble generation medium 15 is located in the jet passage 14P, and the bubble generation medium 15 in this embodiment has a rectangular plate shape. The bubble generation medium 15 is a porous material, such as artificial Graphite (Graphite), silicon carbide, or silicon nitride. It should be noted that the bubble generating medium 15 is connected to the lid 12, and the bubble generating medium 15 and the lid 12 are perpendicular to each other (see fig. 2C, fig. 2C is a schematic diagram of the bubble generating medium 15 connected to the lid 12 according to the first embodiment of the present invention). In this embodiment, there is only one bubble generating medium 15 in the jet passage 14P. However, in other embodiments, a plurality of bubble generation media 15 may be present in the jet passage 14P at the same time, and the bubble generation media 15 are arranged in parallel with each other.
In addition, the average grain size of the bubble generation medium 15 was 10 μm, and the bulk density of the bubble generation medium 15 was 1.80cm3～1.92g/cm3These characteristics help the bubble generation medium 15 to generate dense and fine micro bubbles, for the reasons described in the following paragraphs.
Referring to fig. 2B again, the box cover 12 includes at least one air inlet channel 12P, and the bubble generating medium 15 includes a conducting channel 15P. Further, the conductive path 15P includes a plurality of V-shaped paths 151. The conduction path 15P is in communication with the gas inlet path 12P.
Referring to fig. 2A again, the compressed gas source 13 is used for delivering a compressed gas, such as oxygen, into the gas inlet passage 12P. Thereafter, the compressed gas is introduced into the bubble generation medium 15 through the conduction path 15P to generate ultra fine bubbles on the outer surface of the bubble generation medium 15. Also, since the V-shaped channels 151 are almost filled with the bubble generation medium 15, the compressed gas can be conducted to each region of the bubble generation medium 15 through the V-shaped channels 151.
In addition, the jet 16 is connected to the box portion 14, and the jet 16 is used for injecting a water flow into the jet channel 14P. Specifically, the water jet 16 is jetted into the jet flow path 14P through a water flow having a constant velocity, so that the water flow collides with the outer surface of the bubble generation medium 15, and the ultrafine bubbles just emerging from the outer surface are flushed into the water. This prevents the formation of large bubbles on the surface of the bubble generation medium 15, thereby increasing the probability of the bubbles dissolving in water. In addition, since the bubbles generated by the ultra-fine bubble generator 10 are rapidly dissolved in the water, the aquatic organisms have sufficient oxygen content to maintain normal physiological activities.
Referring to fig. 2D, fig. 2D is a schematic view illustrating the box portion 14 having a plurality of magnetic strips 14M. The inner surface of the case portion 14 is provided with a plurality of magnetic strips 14M parallel to each other, and the magnets 14M are made of permanent magnets. The magnetic strips 14M extend in a direction perpendicular to the direction of the water stream ejected by the jet 16. Thus, the water flow passing through the magnetic strips 14M is converted into magnetized water, and the principle of the magnetized water is briefly described as follows:
magnetic flux rate Φ according to Faraday's law (as described in the following equation (1))BThe change of (a) generates an induced electromotive force epsilon, and since water is a polar molecule, the induced electromotive force epsilon changes the arrangement of water molecules, thereby affecting the properties of water. In this case, the magnets 14M are arranged in a grid, and the extending direction thereof is perpendicular to the direction of the water flowTherefore, the magnetic flux sensed by the water flow passing through the magnetic stripe 14M is continuously changed, thereby generating an induced electromotive force e and further changing the properties of the water.
Referring to fig. 2E, fig. 2E is a schematic diagram of another embodiment of the microbubble generator 10'. The difference between the microbubble generator 10' and the microbubble generator 10 is that: the ultrafine bubble generating apparatus 10' includes two lid units 12, two compressed gas sources 13, two casing units 14, and two bubble generating media 15. In this case, the two casing parts 14 can be connected in series, so that the water jet ejected from the water jet 16 can impact the outer surfaces of the two bubble generation media 15 at a time, so that more ultra-fine bubbles are flushed into the water.
Referring to fig. 3, fig. 3 shows the analysis result of the microbubble particle size test conducted in the laboratory for the bubble generating medium 15 and the control group according to the present invention. Among them, the porous material having the designation "17-600-19" corresponds to the bubble generation medium 15 of the present embodiment. That is, name unit
The porous material of 17-600-19 has a volume density of cm31.80～1.92g/cm3. In addition, the porous material with the designation "17-600-p" belongs to the control group of the bubble generation medium 15, and the volume density of the control group is less than 1.80g/cm3。
From the analysis result of the microbubble particle size test in FIG. 3, it can be seen that the number of microbubble particles generated by the porous material with the name unit 17-600-19 is greater than that of the control group in the case of three stages with different time lengths. And the number of the first and second electrodes,
the porous material of 17-600-19 is 1.0Kg/cm2Can form nine thousand eight million bubbles, far exceeding the number of bubbles formed by the control group (three thousand three million bubbles). Therefore, the analysis result of the microbubble particle size test of fig. 3 has confirmed that the microbubbles generated by the bubble generating medium 15 of the present case are, in addition to being finer,the number of microbubbles can be excellent, which is not achieved by other porous materials with different densities.
Further, the outer surface of the bubble generation medium 15 in the above may also be treated by way of ultra-high density polishing. According to the experimental results, it is also possible to help the bubble generation medium 15 to generate finer microbubbles.
Referring to fig. 4A and 4B, fig. 4A is a perspective view of a superfine bubble generating device 20 according to a second embodiment of the present invention, and fig. 4B is a cross-sectional view of a main body 24 and a bubble generating medium 25. The ultrafine bubble generating apparatus 20 includes a main body 24, a compressed gas source 13, two bubble generating media 25, and a jet 16. The bubble generating medium 25 is a tubular body, and two bubble generating media 25 are serially connected in the main body 24, and the bubble generating medium 25 is made of porous material. It should be noted that an annular space 25S is formed between the main body 24 and the bubble generating medium 25. In addition, the main body 24 includes at least one air inlet channel 24P, and the air inlet channel 24P and the annular space are communicated with each other.
In addition, the compressed gas source 13 is used for delivering a compressed gas to the gas inlet channel 24P. Thereafter, the compressed gas is introduced into the bubble generation medium 25 through the annular space 25S, so that ultrafine bubbles are generated on the inner surface of the bubble generation medium 25. In other words, the ultra fine bubbles are formed in the inner space of the tubular body.
In addition, the water jet 16 is connected to the main body 24, and the water jet 16 is used to jet a water flow to the inner space of the tubular body, so that the water flow will impact the inner surface of the bubble generating medium 25 to flush the just-emerged ultra-fine bubbles into the water. Thus, the ultra-fine bubble generator 20 can prevent the formation of large bubbles on the surface of the bubble generation medium 25, thereby increasing the probability of the bubbles dissolving in water. In addition, compared to the rectangular plate-shaped bubble generation medium 15, the inner water flow of the tubular bubble generation medium 25 is stable (the rectangular plate-shaped bubble generation medium 15 splits the water flow), and no turbulent flow is generated, so that large bubbles are not easily formed.
Referring to fig. 5A and 5B, fig. 5A is a perspective view of a superfine bubble generating device 30 according to a third embodiment of the present invention, and fig. 5B is a cross-sectional view of a main body 34 and a bubble generating medium 35. Fig. 5B is a sectional view showing the main body portion 34, the rotating mechanism 36, and the bubble generation medium 35. The ultra-fine bubble generating device 30 includes a compressed gas source 13, a main body 34, a rotating mechanism 36 and a plurality of bubble generating media 35. The main body portion 34 includes an air inlet region 341, a central axis region 342, a rotation region 343, and an air separation region 344, the air inlet region 341 is connected to the central axis region 342, the air inlet region 341 includes an air inlet passage 341P, the central axis region 342 includes a first central passage 342P, and the first central passage 342P and the air inlet passage 341P are communicated with each other.
In addition, the rotating area 343 is connected to the middle shaft 342 and the rotating mechanism 36, and the rotating area 343 includes a second middle channel 343P, and the second middle channel 343P is in communication with the first middle channel 342P. In addition, the gas distribution section 344 is connected to the rotating section 343, the gas distribution section 344 includes a main channel 344A and a plurality of branch channels 344B, the main channel 344A is communicated with the second middle channel 343P, and the branch channels 344B are communicated with the main channel 344A. In addition, the outer surface of the air distribution region 344 is provided with a plurality of parallel magnetic strips 344M, and the magnetic strips 344M are also made of permanent magnets.
Referring to fig. 5B again, each bubble generating medium 35 is connected to the sub-air region 344 of the main body 34, the bubble generating medium 35 is made of a porous material, and the bubble generating medium 35 is located under the water surface. It is noted that each of the branch channels 344B corresponds to a respective one of the bubble generating mediums 35.
The compressed gas source 13 is configured to deliver a compressed gas into the gas inlet 341P. Thereafter, the compressed gas is sequentially introduced into the first intermediate passage 342P, the second intermediate passage 343P, the main passage 344A, and all the branch passages 344B. Thereafter, the compressed gas is introduced into the bubble generation medium 35 through all the branch passages 344B, so that ultrafine bubbles are generated on the outer surface of the bubble generation medium 35.
In addition, the rotating mechanism 36 is used to rotate the air distribution area 344. In detail, when the rotating mechanism 36 rotates rapidly, the rotating mechanism 36 drives the rotating area 343 and the air separation area 344 to rotate simultaneously. Therefore, the bubble generation medium 35 located below the divided region 344 also moves. Thus, the outer surface of the bubble generation medium 35 is also impacted by the water flow, and the generated ultra fine bubbles are washed out in the water.
In addition, when the air distribution section 344 rotates, the extension direction of the magnetic strip 344M is perpendicular to the water flow direction. Thus, the water passively passing through the magnetic strips 344 is also converted into magnetized water.
In the above, the compressed gas is oxygen as an example. However, in other embodiments, the compressed gas may be ozone to increase the concentration of ozone in the water.
In summary, the ultra-fine bubble generating device of the present embodiment can reduce the formation of larger bubbles on the surface of the bubble generating medium, so as to increase the probability of the bubbles dissolving in water. In addition, it can generate dense and fine ultra-fine bubbles, which is helpful to maintain the oxygen content in water.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and any equivalent replacement and modification made by those skilled in the art without departing from the spirit and scope of the present invention are deemed to fall within the protection scope of the present invention.
