Description Apparatus and method for ultrafine powder fluidization

The present invention relates to an apparatus and a method for miniaturizing a flowable object (hereinafter also referred to as “powder fluid”) that cannot maintain a certain shape such as a liquid, a fluid, a powder, and a granule. . Background art

The inventor of the present invention disclosed in Japanese Patent Application Nos. 08-22026 and 8-2997129 that, for example, when cooling the inside of a greenhouse, water was used as much as possible. It was suggested that atomization in the form of fine mist is effective for promoting vaporization.

Also, Japanese Patent Application No. 9-5099-16 proposed a technique for producing salt by spraying seawater to vaporize water and crystallize salt. It is important to make the size as small as possible in order to increase manufacturing efficiency.

In Japanese Patent Application No. 9-111103, two or more workpieces, such as powders, granules, gas bodies, and liquids, are sucked to be fined and mixed, and then mixed to form a liquid. It was suggested to take in. In this way, not only liquids but also fluids, powders, granules, and the like can be mixed with two or more powdered fluids, or mixed with a powdered fluid and a gaseous body. Techniques for miniaturization are required as much as possible, especially for ultra-miniaturization.

However, in the above-mentioned proposed technology, It was impossible to reduce the size to the limit, and as a result, it was impossible to achieve the intended purpose sufficiently.

The technical problem of the present invention is to pay attention to such a problem and to make it possible to make the powder fluid finer to the utmost by relatively simple technology. Disclosure of the invention

The technical problem of the present invention is solved by the following means. Item 1 is a rotating disk formed by connecting a plurality of impellers extending from the center to an outer peripheral direction between opposing disks arranged opposite to each other to a rotary drive shaft. The present invention is directed to a device having an opening for supplying an object to be processed. A pole is provided on the outer periphery of the rotating disk with a plurality of rigid bodies disposed at a slight gap from the outer end of the blade to cut an object to be processed slightly projecting from the outer end of the blade. It is a miniaturization device. Each blade and the opposing disk may be connected by a caulking structure as shown in FIG. 1, or may be an integrally molded structure as shown in FIG.

As described above, a structure is provided in which a plurality of rigid bodies are provided on the outer periphery of the rotating disk with a slight gap from the outer end of the blade to cut a workpiece slightly projecting from the outer end of the blade. Therefore, the object to be processed before being shaken off by the centrifugal force by each blade is cut by colliding with the rigid body, and is further subdivided and miniaturized. As a result, the vaporization of water from the object to be processed and the mixing and compounding of two or more types of object to be processed are performed extremely smoothly, thereby improving the processing efficiency.

The second term includes a rotating disk formed by connecting an impeller, which is arranged with a plurality of blades extending in the outer peripheral direction from the center between opposed disks arranged to face each other, to a rotary drive shaft, In the center, an opening for supplying the workpiece is formed In a device that has been configured, a compressed air flow is injected in the direction tangential to the rotating disk in a direction opposite to the rotating direction of the rotating disk, at a slight distance from the outer circumference of the rotating disk, and at an angle to the surface of the rotating disk. And a compressed air flow jet nozzle for cutting the object to be processed, which slightly protrudes from the outer end of the blade, using a compressed air flow.

In this way, the compressed air flow is injected in the tangential direction of the rotating disk in the direction opposite to the rotating direction of the rotating disk, and the workpiece slightly projecting from the outer end of the blade is cut by the compressed air flow. , Can be further subdivided and miniaturized. As a result, vaporization of water from the object to be processed and mixing and compounding of two or more types of the object to be processed are performed extremely smoothly, thereby improving the processing efficiency.

In particular, because the compressed air flow is injected obliquely to the surface of the rotating disk, the fine <: cut ultra-fine particles hit the nozzle, disturbing the nozzle, and There is no danger that the fine particles will recombine and return to larger particles.

In addition, the ultra-fine particles are deflected from the rotating disk, and the ultra-fine particles are scattered and dispersed by the compressed air flow, so that they are not concentrated in one place, and are not concentrated. Processing efficiency is further improved. Also, more nozzles can be arranged.

The third term relates to a rotating disk formed by connecting a rotating drive shaft to an impeller arranged with a plurality of blades extending from the center in an outer peripheral direction between opposed disks arranged to face each other,

An opening for supplying the object to be processed is formed in the center,

The rotational speed of the rotating disk is V so that an air wall is generated around the rotating disk.

ν = / P / P In order to be able to ascend to high speed, drive the rotating disk through a speed increasing means such as a pulley and a belt or a gear mechanism to achieve high-speed rotation, or use a high-speed motor with an inverter to achieve high-speed rotation. This is an ultra-miniaturized device that has been realized.

In this way, by using a speed-increasing means and a high-speed motor with an inverter, the peripheral speed of the rotating disk is extremely increased to form an air wall, and the same function as a rigid body or compressed air flow can be obtained. The processing efficiency is greatly improved.

In a fourth aspect, a collision wall surrounding the rotating disk is provided outside the rotating disk according to the first, second, or third item, and the ultrafine body cut by the cutting means collides with the rotating disk. This is a microminiaturization device with a possible structure.

As described above, since the collision wall surrounding the rotating disk is provided, the ultrafine body cut by the cutting means is confined and floated in the collision wall, so that the opportunity of contact between the ultrafine particles increases. . In addition, since the ultrafine particles which have collided and bounced off the collision wall come into contact with the next arriving ultrafine particles or floating ultrafine particles, the chances of contact between the ultrafine particles further increase. Therefore, it is suitable for mixing or combining two or more kinds of objects to be treated.

Item 5 is that an object to be processed is provided at the center of a rotating disk formed by connecting an impeller, which is arranged with a plurality of blades extending in a peripheral direction from the center between opposing disks arranged to face each other, to a rotary drive shaft. When ultra-fine processing is performed using a device provided with an impact wall surrounding the rotating disk outside the rotating disk, an aqueous solution in which calcium is dissolved and at least carbon dioxide are provided. Is supplied simultaneously from the supply port of the rotating disk into the rotating disk, and the calcium water cut by the cutting means is An ultrafine method characterized in that a gas containing a solution and carbon dioxide collides with the collision wall and is repelled, thereby significantly increasing the chance of calcium and carbon dioxide contacting and combining. .

In this way, using a device having a collision wall surrounding the rotating disk as described in Section 4, an aqueous solution containing calcium dissolved therein and a gas containing carbon dioxide are supplied from the supply port of the rotating disk to produce ultrafine particles. According to the method in which calcium and carbon dioxide are repelled and bounced off the collision wall, the number of opportunities for calcium and carbon dioxide to come into contact with each other is significantly increased, so that calcium carbonate can be efficiently generated and CO ₂ can be effectively reduced.

Item 6 is that an object to be processed is provided at the center of a rotating disk formed by connecting an impeller arranged with a plurality of blades extending from the center in the outer peripheral direction between opposed disks arranged to face each other to a rotary drive shaft. Using a rotating disk having an opening for supplying the same, seawater or a liquid to be treated in which any substance is dissolved is supplied from the center opening of the rotating disk, and a slight distance from the outer end of the blade is supplied. By providing cutting means such as a rigid body, a compressed air flow, or an air wall, the liquid to be processed slightly protruding from the outer end of the blade is cut to be extremely fine, and at the same time, the dispersion is enlarged as in a blower or the like. This is an ultrafine method characterized by accelerating the vaporization of a liquid using a means and separating the liquid into a dissolved substance of seawater or liquid and water or liquid.

In this way, by miniaturizing the object to be processed by using the cutting means, and by accelerating the vaporization of the water or liquid by using a dispersion-enlarging means such as a blower, the dissolved substance of the seawater or liquid and the water or The process of separating from the liquid is performed efficiently.

Clause 7 is to connect an impeller, which is arranged with a plurality of blades extending from the center in the outer peripheral direction between opposing disks arranged to face each other, to a rotary drive shaft. A rotating disk having an opening for supplying an object to be processed in the center thereof, and having a plurality of air suction holes formed in at least one of the opposed disks. The above cutting means is not always necessary o

As described above, since a plurality of air suction holes are formed in at least one of the opposed disks of the rotating disk, the flow of the object to be processed in the rotating disk is caused by the airflow flowing from the air suction holes. Finer fog is generated more smoothly because it flows while diffusing into the entire space inside the rotating disk. In addition, when a cutting means such as a rigid body, a compressed air flow, or an air wall is used in combination, a more uniform and stable ultrafine-graining action can be obtained.

Next, an embodiment will be described as to how the apparatus and method for miniaturizing a powder fluid according to the present invention are actually embodied. FIGS. 1 to 3 show a rotary disk for atomization proposed by the inventor of the present invention in Japanese Patent Application No. Hei 8-27971.

Fig. 1 shows a single type, in which a plurality of blades 3 extending from the center in the outer peripheral direction are sandwiched and fixed in a space 6 between opposed disks 1 and 2 arranged opposite to each other, and fixed. 4 is configured. That is, the protruding pieces on both sides of each blade 3 are protruded from the holes of the opposed disks 1 and 2, and are caulked and fixed like the caulking portion 9.

The output shaft of the motor M, that is, the drive shaft A is fixed at the center of one of the opposed disks 1. The center of the other opposed disk 2 is provided with an opening 5 for water supply. Accordingly, when water is supplied with the water pipe end 8 directed toward the opening 5, the water is radially blown off from the space 6 between the adjacent blades 3 by centrifugal force. At this time, when the rotation speed of the impeller 4 is a high-speed rotation such as, for example, 10,000 rotations or more, a fine mist is formed.

That is, when the impeller 4 rotates at a high speed in the direction of the arrow a1 (left rotation in the figure), the water sucked from the openings 5 moves outward by centrifugal force along the front face 3a of each impeller 3, and finally ends. Arrow 2 from the outer end of the blade 3 by centrifugal force She is swung away. Such a movement is performed at a high speed, and becomes mist when scattered in the direction of the arrow 2.

Also, the fog scattered in the direction of arrow a2 is blown away by centrifugal force, so that the reaching distance becomes longer.

FIG. 2 shows an embodiment in which the impeller 4 of FIG. 1 is integrated back to back, and the center of the intermediate disk 1 is fixed to the output shaft A of the motor M. In the center of the intermediate disk 1, a window 7 is opened between the connecting portion 1 a to the motor shaft, and about half of the water supplied from the water supply pipe tip 8 is on the left side of the window 7. impeller 4 enters into _a of, the other half into the right side of the impeller 4 b. The motor shaft A can be fixed to the center of the left disk 2a, and the center of the intermediate disk 1 can be a circular opening.

In FIG. 1 (2), the blades 3 are arc-shaped, but the shape is not limited as long as it can be atomized efficiently by centrifugal force. The distance between the disk 1 and the disks 2, 2a, and 2b is large at the center and narrow at the outer periphery to increase the atomization efficiency, but is not limited to this structure. Therefore, it is possible to increase the distance B between the two opposed disks 1 and 2 (2a, 2b) to a size approximately equal to or larger than the radius of the impeller 4, and to keep the distance B constant. Then, both opposed disks 1 and 2 (2 a, 2 b) can be made parallel to each other.

1 and 2, the disks 1, 2, 2a, 2b and the blade 3 are made as separate parts, and a means such as a force crimping section 9 shown in FIG. 1 is used. It can be manufactured by combining them later. Alternatively, as shown in Fig. 3, one disk 1 and each blade 3 are molded integrally with a resin, and the other disk 2 in Fig. 1 is fixed to the blade 3 by screwing or bonding. It is also possible. That is, the production method does not matter.

Also, as shown in Fig. 1 (2), the distance between the blades 3 is wider toward the outer periphery, but by adding another blade between the blades 3, As in the case of Fig. 3, it is possible to prevent the outer circumference from becoming too wide.

In the above description, water is supplied from the opening 5, but liquid, fluid, powder, granules, and the like other than water can also be supplied.

The present invention has the following improvements in order to miniaturize liquids, fluids, powders, granules, and the like using such a rotating disk having an impeller structure.

As shown in FIGS. 1 and 2, in a rotating disk 4 having a plurality of blades 3 sandwiched between opposed disks 1 and 2, as shown in FIG. At intervals G, a plurality of rigid bodies 10 for cutting the atomized mist are arranged at intervals. The small gap G is preferably as small as possible as long as the rotating disk 4 does not touch the rigid body 10.

In this way, if the rigid body 10 is arranged outside the rotating disk 4 with a small gap G, the atomized mist is instantaneously moved to the rigid body 10 before being shaken off at the outer end of each blade 3. Is cut off. As a result, a single mist of water droplets is divided into a plurality of extremely fine water particles, resulting in an extremely fine mist, which facilitates vaporization of water.

As the number of rigid bodies 10 increases, the efficiency of ultrafineness becomes higher.However, if the distance between the rigid bodies 10 is too small, there is a risk that extremely finely divided fog may be confined. Some space is required between each rigid body 10 · 10 so that can flow out. It is also effective to use a compressed air flow as a means having the same function as the rigid body 10. That is, as shown in FIG. 5, a plurality of compressed air nozzles 12 are arranged at the outer peripheral position of the rotating disk 4 so that the compressed air flow 11 can be jetted in a tangential direction of the rotating disk 4. The direction of the nozzle 12 is oriented such that the direction of jet of the compressed air flow 11 is opposite to the direction of rotation of the rotating disk 4. Also, as in the case of the rigid body 10 described above, the blades 3 are arranged so that the compressed air flow 11 is generated at a position of a slight distance G from the outer end.

In this way, when the compressed air flow 11 is generated in a direction opposite to the rotation direction of the rotating disk 4 and tangentially at a position of a small gap G from the outer end of each blade 3. A dense air wall can be formed by the compressed air flow 11. As a result, the atomized mist before being shaken off by the outer ends of the blades 3 is instantaneously hit by the compressed air flow 11 and is cut off to be extremely fine.

The ultrafine mist cut in this manner is blown off by the compressed air flow 11. Therefore, as shown in FIG. 4, unlike the case where the rigid body 10 actually exists, the rigid body 10 does not cause the extremely fine mist to be trapped, and can smoothly spray the mist.

Compressed air flow 1 1 Force As shown by the arrow 11a in Fig. 5 (2), if it is in the direction parallel to the surface of the rotating disk 4 (in the direction perpendicular to the drive shaft A), the extremely fine mist is generated by the nozzle. Nozzle 1 2 is in the way because it hits 1 2. Further, when the mist hits the nozzle 12, there is a risk that the extremely fine mist will recombine and return to large particles.

However, as shown in Fig. 5 (2), by arranging the nozzle 12 at an angle of 0 with respect to the surface of the rotating disk 4, the nozzle 12 can be compressed from an oblique direction. It has a structure to blow out the airflow 11. Therefore, there is no risk that the nozzles 12 will be in the way or that extremely fine particles will recombine. Moreover, the ultrafine particles are deflected from the rotating disk 4 by the compressed air flow 11 and are scattered by being scattered far away, so that they are not concentrated in one place, and the processing efficiency such as vaporization is improved. Further improve. Further, more nozzles 12 can be arranged. Compressed air flow 1 1 Jet angle »Free

As described above, it is effective to provide the rigid body 10 or to generate the compressed air flow 11, but the rigidization by the rigid body 10 and the compressed air flow 11 is not effective. This is made possible by the high relative speed between the velocity and the rigid body 10 or the compressed air flow 11.

Therefore, if the peripheral speed of the rotating disk 4 can be made much higher than in the case of FIGS. 4 and 5, even if the rigid body 10 and the compressed air flow 11 are not present, the rigid body 10 An ultra-miniaturization effect similar to the case where the compressed air flow 11 exists can be expected.

That is, in order to enable the generation of an air wall similar to that of the compressed air flow 11 or the like, as shown in FIG. 6, the peripheral speed V at the outer end of the blades 3... It is necessary to raise it. Such high-speed rotation can be realized by using a speed increasing means such as a pulley and a belt or a gear mechanism, or by using a high-speed motor with an inverter.

Next, the reason will be described. Now, when the peripheral speed V at the outer end of the rotating disk 4 is relatively small, the resistance between the rotating disk 4 and the surrounding air is Caused by the viscosity of the force F. Is given by F 0 =-a V-(1)

Is proportional to the speed.

As the speed of the rotating disk 4 increases, the rotating disk 4 generates turbulence in the fluid, so that the resistance increases in proportion to the square of the speed. In general, the resistance F _Q is

Fo = a V + b V ² … (2)

The coefficient a and b have a term proportional to the velocity and a term proportional to the square of the velocity. The coefficients a and b are determined by the shape of the rotating disk 4 and the type of fluid around it.

When considering the motion of the rotating disk 4 in the air, the term proportional to the square of the velocity becomes important, and the resistance coefficient C. Using,

F _D = —— C _D Αν ² … (3)

It is said to be 2.

P: Fluid density

A: Effective sectional area of the workpiece

C _D : Dimensionless drag coefficient determined by the shape of the rotating disk 4

When the in gas rotating disc 4 rotates, the dynamic pressure ^1/2 p V 2 is small such fast compared to pressure P of the gas can also be treated takes as a liquid which does not shrink the gas. However, the peripheral speed V of the rotating disk 4 is',

v = V P / P '(4)

In this case, the effect of gas compression becomes significant and the effect of the inertial resistance increases, and the flow state and the resistance become very different from those at low speed. In other words, the compression resistance of air must be considered completely as a physical force. Considering the inertial resistance of this rotating disk, the end speed of the rotating disk 4 (the peripheral speed of the outer end of the blades 3 ...) V

v = 7 P /… (4)

In the state close to, the rigid body 10 and the compressed air flow 11 1 as shown in Fig. 4 and Fig. 5 naturally generate air walls having the same function as the rigid body 10 and the compressed air flow 1 1. Becomes unnecessary.

Since ν = Γ ω, to increase V, the radius r may be increased or the angular velocity ω may be increased. Therefore,

R and ω are adjusted so that

Of course, when the peripheral speed V of the rotating disk 4 is small, the rigid body 10 in FIG. 4 and the compressed air flow 11 in FIG. 5 are also very effective.

In FIG. 7, a dynamic summary of the radius r and the peripheral speed V of the rotating disk 4 is given.

r: radius of rotating disk 4

ω: angular velocity of rotating disk 4

V: Speed around the outer circumference of the rotating disk 4

η: Number of rotations per unit time

V = r ω

ω = 2 π n

ν = 2 π τ n

Next, the relationship between the peripheral speed V of the rotating disk 4 and the radius r will be considered.

Now, the sound velocity V at t ° C is

v = 3 31.5 + 0.6 t (mZs ec) Given by Assuming t = 40 ° C,

v = 3 31.5 + 24 (m / sec) = 35.5.5 m / sec When converted to minute speed,

v = 3 5 5.5 X 6 0 = 2 1 3 3 0 m / m i n

Since v = 2 7 n r n (n = r pm)

If r = 0.20 m,

2 1 3 3 0 = 2 X 3.14 X 0.2 x n

2 1 3 3 0

n = = 1 6 9 8 2 r pm

If r = 0.25 m,

2 1 3 3 0 = 2 X 3.14 X 0.25 X n

n = = 1 3 5 8 5 r pm

After all, if the radius r of the rotating disk 4 is 20 cm, high-speed rotation of 16982 rpm or more is required, and if the radius r is 25 cm, 1358 5 rpm is sufficient. become. If these conditions can be satisfied, the rigid body 10 in FIG. 4 and the compressed air flow 11 in FIG. 5 become unnecessary.

If a large-power motor is used to drive a large rotating disk 4 with a radius r larger than 25 cm, the number of rotations can be further reduced.

If seawater is made extremely fine as an object to be treated using the above-described apparatus or method, the seawater becomes extremely fine mist, so the water content in the salt production method of Japanese Patent Application No. 9-509916 is filed. Evaporation is very efficient, salt mass production is easier and salt crystals are finer.

In addition, when various solutions are miniaturized to promote vaporization of water, It is also easy to separate the disassembly from water or liquid.

Furthermore, when the finely divided fine fog is blown away further and dispersed and expanded using a blower, vaporization of water and liquid is further promoted. At this time, it is needless to say that using hot air or hot air is more effective.

As disclosed in Japanese Patent Application No. 9-111173, the apparatus or method of the present invention simultaneously sucks powder and granules or gas and liquid into a rotating disk 4 to make it extremely fine. It is extremely effective when mixed and taken into a liquid. In other words, as shown in Fig. 4, the rigid body 10 and the compressed air flow 11 in Fig. 5, and as shown in Fig. 6, the peripheral Collisions can be made one after another to promote mixing or compounding, and bonding or compounding is promoted by increasing the chances of contact between different types of substances.

As illustrated in FIG. 4, a collision wall 13 surrounding the rotating disk 4 is provided outside the rotating disk 4 so that the microfine body cut by the cutting means as described above is confined. It is. When the distance R between the outer periphery of the rotating disk 4 and the collision wall 13 is small, the ultrafine particles collide with the collision wall 13 and rebound.

As a result, the microfine particles are trapped and drifted, increasing the chance of contact between the ultrafine particles. Further, the ultrafine particles colliding with and bounced off from the collision wall 13 come into contact with the next arriving ultrafine particles or floating ultrafine particles, and the chances of the ultrafine particles contacting each other are further increased. Therefore, it is suitable for a case where two or more kinds of objects to be treated are mixed or combined.

The radius r of the rotating disk 4 is about 0.05 m to 1.0 m depending on the application. Dimensions are possible. Further, the distance R between the outer periphery of the rotating disk 4 and the collision wall 13 may be about 0.01 m to about L 0 m.

In this case, the calcium hydroxide is dissolved in the aqueous solution supplied to the rotating disk 4 from the supply port 5, and the gas containing carbon dioxide is simultaneously sucked into the rotating disk 4 from the same supply port 5. The ultrafine particles that have been cut by the cutting means are bounced off the collision wall 13, thereby significantly increasing the opportunity for the calcium and carbon dioxide to come into contact with each other and to be combined, thereby efficiently generating calcium carbonate. Is done. As a result, CO ₂ reduction can be realized effectively.

FIG. 8 shows an embodiment for smoothing the flow of the object to be processed in the rotating disk 4. The opposed disks 1 and 2 have a large number of holes 14 for air suction. Note that the air suction hole 14 may be opened in only one of the opposed disks 1 and 2.

As indicated by the arrow in Fig. 8 (1), the outside air is sucked into the rotating disc 4 from the hole 14, so that the sucked air causes air to flow between the opposed discs 1 and 2 and the workpiece. By the formation of the flow, the flow of the object to be processed in the rotating disk 4 is smoothed, and the flow in the direction of the outer periphery in the rotating disk 4 and the speed of scattering in the form of mist increase.

In addition, due to the interaction between the air flow sucked through the holes 14 and the object sucked through the openings 5, the outer disks move in the outer circumferential direction without any three-dimensional wavy movement between the opposing disks 1 and 2. As a result, the object to be processed is three-dimensionally spread in close contact with the inner surfaces of the opposed disks 1 and 2, and further miniaturization is promoted.

As described above, the action of the air suction hole 14 occurs before reaching the cutting means as described above. It works extremely effectively even in a structure that does not use cutting means as shown in FIGS. 4 to 7, such as the rotating disk proposed by the inventor.

The rotating disk 4 according to the present invention can be used in an upright state or in a horizontal state. Alternatively, it may be inclined. Therefore, the position and orientation of the rotating disk 4 are not restricted at all. In addition, the rotary disk 4 itself can be rocked or swung with each drive source. Industrial applicability

According to the first aspect, a plurality of rigid bodies are provided on the outer periphery of the rotating disk with a slight gap from the outer end of the blade to cut a workpiece slightly projecting from the outer end of the blade. Due to its structure, the object to be processed before it is shaken off by the centrifugal force by each blade is cut by colliding with the rigid body, and is further subdivided and miniaturized. As a result, vaporization of water from the object to be processed and mixing and combining of two or more types of the object to be processed are performed extremely smoothly, thereby improving the processing efficiency.

According to the second term, a compressed air flow is injected in a direction tangential to the rotating disk in a direction opposite to the rotating direction of the rotating disk, and the workpiece slightly projecting from the outer end of the blade is cut by the compressed air flow. It can be further subdivided and miniaturized. As a result, vaporization of water from the object to be processed and mixing and compounding of two or more types of the object to be processed are performed extremely smoothly, thereby improving the processing efficiency.

In particular, the compressed air flow has a structure that is injected obliquely to the surface of the rotating disk, so the finely cut fine particles hit the nozzles, hinder the nozzles, or become extremely fine. There is no danger that they will recombine and return to a large particle. In addition, the ultrafine particles are deflected from the rotating disk, and the ultrafine particles are scattered and dispersed by the compressed air flow, so that they are not concentrated in one place. Processing efficiency such as vaporization is further improved. Also, more nozzles can be arranged.

According to paragraph 3, by using a speed-increasing means or a high-speed motor with an inverter, the peripheral speed of the rotating disk is extremely increased to form an air wall, so that a function similar to that of a rigid body or compressed air flow can be obtained. As a result, the processing efficiency is significantly improved.

According to the fourth aspect, since the collision wall surrounding the rotating disk is provided, the ultrafine bodies cut by the cutting means collide with the collision wall and bounce off, so that the ultrafine bodies contact each other. More opportunities. Therefore, it is suitable when mixing or combining two or more kinds of objects to be treated. As described in paragraph 5, using a device having a collision wall as described in paragraph 4, an aqueous solution containing dissolved calcium and a gas containing carbon dioxide are supplied from the supply port of the rotating disk to produce extremely fine particles. According to the method in which calcium and carbon dioxide are repelled by the collision wall, the number of opportunities for calcium and carbon dioxide to come into contact with each other is remarkably increased, so that calcium carbonate can be efficiently generated and CO ₂ can be effectively reduced.

According to paragraph 6, seawater or liquid dissolved matter and water are used to minimize the size of the object to be processed by using cutting means and to accelerate vaporization of water or liquid by using dispersion expansion means such as a blower. Alternatively, the process of separating the liquid from the liquid is performed efficiently.

According to paragraph 7, since a plurality of air suction holes are formed in at least one of the opposed disks of the rotating disk, the flow of the object to be processed in the rotating disk is further increased by the airflow flowing from the air suction holes. It will be smooth Since it flows while diffusing into the entire space inside the rotating disk, fine fog is generated smoothly. In addition, when cutting means such as a rigid body, a compressed air flow, and an air wall are used together, a more uniform and stable micronizing action can be obtained.
