In the conventional emulsification apparatus described above, the atomization process is advanced by converting the liquid to be treated at a high pressure into a high-speed flow and changing or colliding the flow path of the high-speed flow. However, since the collision flow path for obtaining the atomization effect is constituted by a narrow passage, there is a problem that the pressure loss is large, that is, the flow rate is small and the high-speed flow is attenuated. This means that the energy of the high-speed flow given to the fluid in order to advance the atomization process is changed to heat energy in the middle of the flow path and lost.

  Moreover, the pressure loss cannot be reduced structurally with the nozzle in the conventional emulsification apparatus. According to the conventional nozzle structure, the amount of heat generation is very large, and heat that generates burns when directly touching the human body is generated. As a result, a large amount of power is required, leading to an increase in product cost and energy cost. Furthermore, since the flow path has a complicated shape, there is also a problem that the solid component is difficult to clean when solidified therein.

Also, the pressure is instantaneously reduced in the mixed liquid filled in the large-diameter cavity, and atomization is performed by mutual interference between the cavitation induced thereby and the high-speed swirling flow.

  Cavitation is a so-called cavity phenomenon in which bubbles are generated when the pressure in the flow of liquid suddenly decreases and the liquid evaporates or gas is generated by liberation of dissolved gas.

In the present invention, the fluid atomizing subject refers laden liquid fluid substances consisting of liquid or powder, if you select the liquid and liquid as substance emulsification is performed, and selects the solid and liquid as substance In some cases, dispersion, crushing, or crushing is performed. When used for intermediate purposes, stirring and uniform mixing are performed.

Dispersion refers to pulverization of fine-particle metal oxides, organic substances, and other inorganic aggregates, and pulverization refers to the refinement of organic or inorganic single particles in a liquid.

  In order to achieve the above object, the atomization apparatus of the present invention is an atomization apparatus for atomizing a substance composed of a liquid or a powder contained in a mixed solution, and is opened at one end of a sealed case. , An introduction port for introducing a high-pressure mixed liquid in which the mixed solution is pressurized, an introduction channel extending linearly from the introduction port into the sealed case, the introduction channel is branched, and the introduction channel A plurality of branch passages arranged in parallel with each other, each of the plurality of branch passages being squeezed with a microhole, a plurality of injection ports for injecting the high-pressure mixed liquid from the other end of the sealed case, And an atomization promoting chamber which is communicated with the mouth and is filled with the mixed liquid in a cavity having a diameter larger than the inner diameter of the branch flow path.

And a storage tank for storing the liquid to be processed after the atomization process discharged from the atomization apparatus.

In the present invention, in order for the liquid mixture injected from the injection nozzle to form a high-speed swirl flow, the discharge introduction pressure of the liquid mixture introduced into the atomization apparatus is set to an ultrahigh pressure of about 1 MPa to 300 MPa using a pressure pump.

FIG. 5 is a schematic diagram showing another shape of the injection port in the injection nozzle, FIG. 6 is a diagram showing the fluid flow in the atomization apparatus, and FIG. 7 is a diagram showing the atomization apparatus. It is a general view which shows the used atomization system.

First, the structure of the atomization apparatus will be described.

The atomization apparatus 10 shown in FIG. 1 is an apparatus for atomizing fine particles or the like mixed in a liquid using the atomization method of the present invention. This apparatus comprises a nozzle assembly 11 including an injection nozzle 50 according to the present invention, a high pressure pipe 12 connected to one end of the nozzle assembly 11, and a low pressure pipe 13 connected to the other end.

  The nozzle assembly 11 has an injection nozzle 50 accommodated in a sealed case composed of a cylindrical flange 21 and a case 22. The sealed case is integrated by abutting the end surfaces of the flange 21 and the case 22 and fastening the bolt 31 inserted from the flange 21 to the case 22. In the present embodiment, as shown in FIG. 2, six notches are formed at equal intervals on the peripheral edge of the flange 21, and bolts 31 are fastened in the axial direction from these notches.

  An inlet 23 is opened at the axial center of the flange 21. The diameter of the introduction port 23 can be increased within a range that does not affect the processing amount. In addition, a linearly extending introduction channel 24 communicates with the introduction port 23, and the downstream side of the introduction channel 24 is further branched into two channels, and a branch channel 25 parallel to the introduction channel 24, 25 is provided. The branch flow paths 25 are arranged so as to be parallel to each other at a target position with the introduction flow path 24 as the center. In the present embodiment, the number of the branch flow paths 25 is two. However, the present invention is not limited to this. For example, three or more branch paths 25 may be provided around the axis of the flange 21 at equal intervals.

  The flange 21 is provided with a hole orthogonal to the introduction flow path 24, and this hole is a processing hole 26 formed when the introduction flow path 24 and the branch flow path 25 are communicated. Accordingly, in order to close the processing hole 26, a female screw 32 is formed at the opening end of the processing hole 26, and a blind plug 33 is screwed and fixed to the female screw 32 by a ground nut 34.

  The nozzle assembly 11 having the above structure has a high-pressure pipe 12 connected to the upstream side thereof. The connection structure is such that a female screw 35 is also formed at the center of the end face of the flange 21, and one end of the high-pressure pipe 12 is screwed and fixed to the female screw 35 with a ground nut 36.

  A taper seal structure is adopted for the joint surface between the high-pressure pipe 12 and the introduction port 23. That is, the end surface of the high-pressure pipe 12 has a tapered shape that becomes narrower toward the tip, and the opening peripheral edge of the introduction port 23 has a slightly wider taper angle. Therefore, when both are fitted, the corner portion at the tip of the high-pressure pipe 12 is brought into close contact with each other, so that the gap is surely closed and the airtightness is maintained.

In this way, the open end of the high-pressure pipe 12 communicates with the introduction port 23, and the high-pressure fluid to be atomized is introduced into the introduction flow path 24 from the high-pressure pipe 12 through the introduction port 23. ing.

  Here, the structure of the injection nozzle will be described.

  As shown in an enlarged view in FIG. 3, the injection nozzle 50 includes a seal member provided on the end surface of the flange 21 and an adapter provided on the opposite surface of the case 22 because the sealed case has a coupling structure of the flange 21 and the case 22. It is comprised by couple | bonding a member. The following seal member and adapter member have a common structure for all branch flow paths 25.

  The seal member includes an annular gasket 51 and a seal 52 having the same diameter. Both are fitted in a recess formed on the end face of the flange 21. On the other hand, the adapter member includes a nozzle body 53 and a nozzle adapter 54. Both are fitted into a recess formed on the opposing surface of the case 22, and a flow path composed of pores 55 is formed at the center thereof.

  A taper seal structure is also employed on the joint surface between the seal 52 and the nozzle adapter 54. That is, the end surface of the nozzle adapter 54 has a tapered shape that becomes narrower toward the tip, and the opening periphery of the seal 52 has a slightly wider taper angle. Therefore, when both are fitted, the corner portion of the tip of the nozzle adapter 54 is brought into close contact with each other, so that the gap is surely closed and the sealing performance is maintained.

  An orifice 56 having a minute hole is provided in the tube of the nozzle body 53, and the flow path of the pore 55 is further restricted. Therefore, the fluid passing through the injection port 57 from the pore 55 has an increased flow velocity, and is converted from the injection port 57 at the tip of the nozzle into a high-speed fluid and is injected. The diameter of the orifice 56 is preferably about 0.1 to 2 mm and the length is about 0.5 to 1 mm. The tip of the nozzle body 53 is tapered so as to reduce the resistance to the high speed fluid. The orifice 56 is preferably made of a superhard material such as ceramics, cemented carbide, diamond or the like so as to have wear resistance with a high-speed fluid.

  A low pressure pipe 13 is connected to the downstream side of the injection nozzle 50. As shown in FIG. 1, the connection structure is such that an opening 27 having a very large diameter is formed on the end face of the case 22 as compared with the branch flow path 25, and one end of the low-pressure pipe 13 is fitted into the opening 27. .

  In this way, the open end of the low-pressure pipe 13 communicates with the injection port 57, and the high-speed fluid injected from the injection port 57 is discharged into the low-pressure pipe 13.

Inside the low-pressure pipe 13, an atomization promoting chamber 41 composed of a hollow portion is provided. Since the atomization promoting chamber 41 is at atmospheric pressure, the pressure of the high-speed fluid ejected from the ejection port 57 drops instantaneously. At this time, if the atomization promoting chamber 41 is filled with fluid, a jet flow and a swirl flow are generated by a plurality of high-speed fluids as shown in FIG. In addition, the high-speed fluid is instantaneously decompressed and cavitation occurs.

Therefore, in the atomization promoting chamber 41, a large shearing force is generated due to the mutual interference between the cavitation induced by the plurality of high-speed flows and the swirling flow, thereby promoting the fluid atomization process. In addition, in order to give a pressure drop efficiently at once, the larger the size ratio between the atomization promoting chamber 41 and the branch flow path 25, the better. As the reference, it is preferable that the inner diameter R1 of the atomization promoting chamber 41 shown in FIG.

  Further, in order to generate a reliable swirl flow in the fluid ejected from the ejection nozzle 50, the ejection port 57 may be inclined at a predetermined angle with respect to the axis of the branch flow path 25. FIG. 5 shows an example in which the angle of the injection port 57 is set so that the high-speed fluid is injected with an inclination of 5 ° with respect to the axis of the branch flow path 25. Of course, the inclination angle of the injection port 57 is not limited to 5 °. For example, the angle may be set so that the high-speed fluid ejected from the ejection port 57 does not collide with the case 22 or the inner wall surface of the low-pressure pipe 13, and the inclination angle can be changed as appropriate. Further, the direction of the inclination may be the outside or the inside.

Further, in the present embodiment, a discharge port 42 is formed at the other end of the low-pressure pipe 13. The discharge port 42 can have a diameter corresponding to the processing amount. Thus, internally atomized treated fluid atomization promoting chamber 41 is discharged to the discharge pipe via the discharge port 42 (not shown).

As described above, in the atomization apparatus 10 of the present embodiment, in particular, the injection nozzle 50 is constituted by two members, that is, a seal member and an adapter member, and the flange 21 and the case 22 that couple them are fastened by the bolt 31. Adopted. For this reason, assembly and disassembly of the apparatus are simple, and exchanging of consumable parts can be easily performed, so that the maintenance is excellent.

Next, the operation of the atomization apparatus.

In the atomization apparatus 10 shown in FIG. 6, the high-pressure fluid containing the substance to be atomized is introduced from the high-pressure pipe 12 into the introduction flow path 24 through the introduction port 23. This is the introduction flow F1.

  Next, the introduction flow F1 is branched by the two branch flow paths 25, 25, and the branched branches F2, F3 are individually introduced into the injection nozzle 50. At this time, the branch flows F2 and F3 flowing in the branch flow path 25 remain in a high pressure state.

As described with reference to FIG. 3, the branch flows F <b> 2 and F <b> 3 flowing through the injection nozzle 50 are narrowed by the micropores when passing through the injection port 57 from the pore 55, and the flow velocity thereof increases. As a result, the fluid that has passed through the injection port 57 is converted into a high-speed flow and is injected into the atomization promoting chamber 41 inside the low-pressure pipe 13.

The atomization promoting chamber 41 is filled with fluid, and the fluid ejected from the ejection nozzle 50 is instantaneously decompressed from the high pressure state. Due to this instantaneous pressure reduction, a cavitation phenomenon occurs in the atomization promoting chamber 41. At the same time, the fluids ejected from the two ejection ports 57 and 57 merge to form a turbulent state between the jet flows F4 and F5 and the swirl flows F6 and F7. Therefore, in the atomization promoting chamber 41, a large shearing force is generated by the mutual interference between the cavitation induced from the two high-speed flows and the high-speed swirl flow, and the atomization process of the fluid proceeds efficiently.

Finally, the fluid which has been treated atomized with the atomization promoting chamber 41 is discharged to the discharge pipe via the discharge port 42 from the low-pressure pipe 13. This is the discharge flow F8.

Above is the configuration of the atomizing device, the following will be described atomization system using the atomization device.

In the atomization system 1 shown in FIG. 7, the pre-mixed liquid (fluid containing the material to be atomized ) is pumped to the atomization device 10 by the pressure pump 4, and emulsification, dispersion, and pulverization are performed in the atomization device 10. Alternatively, atomization such as sterilization is performed.

More specifically, the atomization system 1 has a container 2 for containing water, a hydrophilic fluid, and a hydrophobic fluid as a premixed liquid, and the valve 3 connected thereto is closed to enter the container 2. Add water, hydrophilic fluid, and hydrophobic fluid for storage and premixing. When the premixing in the container 2 is completed, the valve 3 is opened to adjust the flow rate, and the pumping pump 4 is started. The pressure-feed pump 4 pressurizes the premixed liquid to form a high-pressure fluid, which is transferred and introduced into the atomizer 10. The pre-mixed liquid is pressurized to an ultrahigh pressure of about 1 MPa to 300 MPa by the pressure pump 4.

A pressure gauge 5 installed between the pumping pump 4 and the atomization device 10 is for monitoring the pressure of the fluid introduced into the atomization device 10. Further, on the downstream side of the atomizing device 10 is provided with the reservoir 6, the fluid after the atomization process, which is discharged from the atomizer 10 is stored. And the valve 7 connected to the storage tank 6 is opened, the flow rate is adjusted, and the fluid after the atomization process stored in the storage tank 6 can be collected by a predetermined amount. Each part is connected by piping.

According to the atomization system 1, on the large-scale agitation equipment is not required, since the efficient atomization process can be performed in the atomization device 10, it can be realized atomization process of a small uniform particle size distribution.
