Description

Method for producing nanoparticles using bidirectional pulse continuous collision method and apparatus

The present invention relates to a method for producing nanoparticles and a device using a bidirectional pulse continuous collision method that can produce raw materials such as metal, ceramics, organic polymers, etc. used in the industry as high quality nanoparticles. The raw material particles that can be miniaturized are ejected with acceleration from both sides to be manufactured into nano-sized fine particles by a mutual pulse collision method.

In general, in the case of nanotechnology in which micronized raw material particles (metals, ceramics, organic polymers, etc.) are micronized (1 nano = 1 × 10 -9 m), the size of the raw material particles is 1 to 100 nm. It is used in the relevant fields that need to be manufactured.

These fields of application of nanotechnology are widely applied to all fields of human survival, such as biochemistry, microorganisms, textiles, medical, military science, semiconductors, energy, etc., and are required to further expand.

For example, in the case of the life science field, nano-technical sensors can accurately measure biochemical phenomena in the body in a very short time. Also, when electronic devices using nanoparticles are developed, the computational speed becomes very fast. Industrial application will result.

Also, in the field of information and communication, if the communication speed due to nano technology is increased, various applications are possible, such as video conference with people around the world in real time. Moreover, if nano technology is applied to fuel cell devices, small fuel cells can be It will be widely used to solve energy problems while minimizing pollution.

As described above, a nanotechnology for converting raw material particles into nanoparticles has been proposed.

The typical methods for producing metal nanoparticles include various methods such as gas phase method of colliding vapor of metal evaporated at high temperature with gas molecules and quenching it to make fine particles, liquid phase method of adding fine particles by adding reducing agent to solution in which metal ions are dissolved, and solid phase method. The method is being used.

In addition to the above-described method, there is a pulverization method that collides the particles with each other, and the wet pulverization method of the above pulverization method is a method of making a fine particle through the impact by spraying the slurry containing a solid in the solution, and dry and dry grinding method Is a method of injecting solid particles and colliding with the gas stream being accelerated to produce microparticles.

However, the gas phase method, the liquid phase method, and the solid phase method may cause structural deformation or change of physical properties of pure materials due to the input of expensive relative materials. Moreover, the use of catalysts and dispersants may cause damage to the natural environment or pollution. It also created a problem.

In addition, in the case of the wet and dry grinding method, the smaller the solid particles, the more difficult the stable acceleration is, and thus there is a limit and difficulty in producing powders in the unit of nanoparticles. There is a great difficulty in terms of cost due to the wear problem of the nozzle, and there is also a difficulty in producing large-scale fine particles.

Particularly, since conventional metal nanoparticles are manufactured using a metal aqueous solution, a specific oxidizing agent or a metal salt must be used. Also, in the case of making nanoparticles through deposition and separation of a substrate, due to the catalyst used in the manufacturing process, Pollution problems must be solved.

Thus, many studies have been conducted on the removal of oxidants after use and the removal of pollutants using reducing agents.

Therefore, researches to find a way to simplify the manufacturing process through the improvement of the manufacturing process, or research on the physical manufacturing process of miniaturizing by colliding particles rather than chemical methods are in progress.

However, the reality of mass production of high-purity nanomaterials through this process is still in a state of stalemate.

Recently, as shown in 'Bio templated inorganic materials' (see patent US 8431506 B2), researches such as attempting to manufacture nanoparticles using microorganisms have been conducted. There is still a problem, it does not deviate significantly from the conventional manufacturing method.

In addition, recent studies on nanoparticle production using collision methods (Japan P 2003358557) require frontal collisions to increase the efficiency of collisions.

This method is inevitably used to solve the deceleration of the collision object due to the expansion of the material and the increase of pressure due to the high pressure and high pressure in the narrow reaction space, and also to use the simultaneous injection of compressed gas to solve these problems. Adopted the way.

However, this method also had a structural problem as well as pollution, environment, etc. using the compressed gas, there was a limit to the mass production of nanoparticles in this way.

The present invention has been proposed in order to solve the various problems of the prior art as described above, the object of which is to use nano-sized microparticles through direct collision of the same material without using a catalyst, plasma, electrical shock, etc. The present invention provides a method for manufacturing nanoparticles and a device using a bidirectional pulse continuous collision method for manufacturing.

It is another object of the present invention to produce pure and homogeneous nanoparticles without the structural change of the manufactured microparticles and retaining the physical or chemical properties of the elemental materials, while allowing mass production at a low equipment cost. The present invention provides a method for manufacturing nanoparticles and a device using a bidirectional pulse continuous collision method.

The present invention for solving the above problems is characterized by a method for producing nano-sized fine particles by the mutual pulse collision method by mixing the raw material particles that can be miniaturized with a medium of water, and then artificially accelerated from both sides It is done.

The manufacturing apparatus according to this method includes a raw material supply part supplied with a raw material mixture in a state where raw material particles and water are mixed, a raw material accelerating part that can increase the speed of collision, and a collision that makes the raw material collide with each other to produce fine particles. It characterized by comprising a manufacturing unit.

In particular, the present invention was able to solve the problem of the decompression deceleration caused by the collision process by using a cylinder device and a nozzle that can always maintain the situation that the high-pressure or high-speed moving material may collide with the front face, thus It was possible to propose a method and a device that can perform a frontal collision work with high efficiency in miniaturization of particles.

In addition, in the present invention, the supply and collision process of the raw material is designed to work in conjunction so that the operator can perform a continuous repetition process until the desired particle size to enable the production of large-scale nano-size microparticles It is to be done.

As described above, the present invention is very pure and pure by being able to manufacture the raw particles by mixing with water and spraying at high pressure and high speed through the repeated process of mutual frontal collision by the pulse collision method. It has the effect of producing a large number of homogeneous nano-sized microparticles.

In other words, according to the manufacturing process, high purity nanomaterials can be produced economically and in large quantities by using water as a medium, without requiring the use of pollutants generated in the existing fine particle manufacturing process. It will have the effect of not polluting.

In particular, the present invention can be produced by the production of all the raw material particles, such as metal, ceramics, organic polymers to the size of the nano will also have the effect that can be widely used in various industrial fields.

Hereinafter, described in detail by the accompanying drawings for carrying out the present invention in detail.

The present invention provides a method for producing nanoparticles using a continuous pulse bi-directional pulse method in which a raw material supply step of supplying water (H) and raw material particles (P), a raw material mixing step of efficiently and evenly mixing the supplied raw material mixture solution, and a raw material mixture solution Raw material acceleration step to pressurize and spray at high speed, pulse generation step to spray the sprayed raw material mixture with a constant pulse, raw material collision manufacturing step to make the raw material sprayed by the pulse to the front to produce fine particles, nano size It consists of a raw material separation step to separate the water and the fine particles produced by the fine particles.

This will be described in more detail as follows.

Raw material supply stage

The raw material supplying step has a raw material supplying step of supplying raw material particles (P) such as metal, ceramic, organic polymer, etc. for manufacturing to a nano size and water (H) for performing a medium role at an appropriate ratio.

* The raw material particles (P) is a raw material for producing nano-sized fine particles, the size can be varied according to the type of raw material to be prepared, such raw material particles (P) can be sufficiently mixed in water Each is supplied in the ratio of degree, and water (H) uses water as usual.

[Mixing raw materials]

Injecting the raw material particles (P) supplied by the raw material supply step into the tank forcibly mixed evenly through the stirring blade rotated by the driving force of the motor.

In this step, since the raw material particles mixed in the water are made of metal, ceramic, organic polymer, etc., since the specific gravity is higher than that of the medium, the raw material particles are prevented from sinking to the bottom of the water, and the raw material particles are evenly mixed in the water. This is to send the mixed solution as it is to the next step.

[Raw Material Acceleration Step]

The raw material mixture mixed evenly with water is pressurized by the piston moving back and forth in the cylinder and accelerated to high temperature and high pressure, and then sent to the next step, and the raw material acceleration step presses the supplied raw material mixture to high temperature and high pressure to the next step. To send to.

[Pulse generation stage]

It is to improve the grinding efficiency due to mutual frontal collision by repeating the acceleration and deceleration of the raw material mixture discharged by pressing at regular intervals, and by converting the rotational force of the motor into a straight line and compressing and expanding the piston that moves forward and backward. The raw material mixture passing through the rapid acceleration is made at regular intervals to improve the impact force by the pulse.

In other words, if the raw material mixture supplied in the accelerated state by the raw material acceleration step is supplied at the same speed, the efficiency of the mutual collision may be reduced in the next step, the raw material collision manufacturing step, thereby increasing the mutual collision force by repeating the strength and weakness. Let's go.

[Material Collision Manufacturing Step]

The raw material mixture solution, which is pressurized in the above-described raw material acceleration step and supplied at a high speed and at a constant pulse, has a step of being frontally collided with each other by a pair of injection nozzles having different diameters to produce fine particles.

The raw material mixture sprayed from the spray nozzle having a small aperture penetrates into the raw material mixture sprayed from the spray nozzle having a large aperture, and each raw material particle is frontally collided to produce fine particles.

At this time, each injection nozzle facing each other is composed of different diameters, while the injection nozzle of the large diameter is configured to have a size 1.5-2 times that of the injection nozzle of the small diameter, the raw material in the raw material mixture sprayed from each injection nozzle When the particles collide at the front, the grinding efficiency is improved.

This series of steps is carried out continuously and repeatedly until the size of the desired microparticles.

Raw material separation step

After successively repeating a series of manufacturing steps as described above, after the production is made in the size of the desired microparticles, there is a step of recovering to the recovery tank to separate the water and nano-sized microparticles.

The separation step is to separate the nano-sized microparticles and water using a variety of known separation devices, and the separated microparticles are used in the industry as needed, and water is recovered and used.

Therefore, the raw material particles are sequentially manufactured by nano-sized microparticles by going through the manufacturing method as described above, and the microparticles thus prepared are separated from water so that the microparticles can be utilized by industries that require fine grains. Water is used for many other purposes to prevent environmental pollution.

The manufacturing apparatus according to the manufacturing method as described above is shown in detail in Figure 2 below of the accompanying drawings, the present invention is largely divided into the raw material supply unit 100, the raw material mixing unit 200, the raw material acceleration unit 300 as shown in the drawings ), A pulse generator 400, a material collision manufacturing unit 500, and a material separation unit 600.

The raw material supply unit 100 is for supplying the raw material particles (P), such as metal, ceramics, organic polymers, etc. for manufacturing to a nano size with water (H), as shown in Figures 2 and 3 of the accompanying drawings Through the feed hopper 110, the raw material particles and water are mixed and supplied at an appropriate ratio, or the raw material particles and water are separately supplied.

The raw material mixing unit 200 is for mixing the raw material particles and water to be supplied is configured with a cylindrical tank 210, the upper side of the tank 210, the injection hole 211 is supplied with the raw material and water It is connected to the supply hopper 110 is controlled by the valve 212, the reverse side is provided with a recovery port 213 for recycling.

In addition, the motor 220 is installed at the upper center of the tank 210, and the raw material supplied with a plurality of stirring blades 221, which are connected to the rotating shaft of the motor 220 and driven to rotate, are installed inside the tank 210. Stir evenly to mix.

In addition, the lower center of the tank 210 is provided with a discharge port 230 for discharging the raw material mixture sufficiently mixed in the tank 210 to the next step is also controlled by the valve 231.

On the other hand, the outside of the tank 210 may be further provided with a heat exchanger 240 connected to a separate cooling and heating device, the heat exchanger 240 is to maintain a constant temperature in the tank 210 at all times It is to minimize the conversion of the raw material mixture contained therein is oxidized or physical and chemical changes by the temperature change.

Accordingly, the raw material supply unit 100 supplies water and raw material particles at an appropriate ratio through the feed hopper 110, and the raw material mixing unit 200 mixes the raw material particles and water supplied as described above evenly.

That is, when the raw material particles are supplied to the inside of the tank 210 together with water through the inlet 211 of the raw material mixing unit 200, the stirring blade 221 is rotated while the motor 220 is driven, and thus the tank Raw material particles supplied into the 210 are mixed evenly with water to form a raw material mixture.

Mixing the raw material mixture as described above is a raw material particles, such as metal, ceramics, organic polymers, etc. for manufacturing to a nano size has a higher specific gravity than water so as to be evenly mixed with water while preventing precipitation in the tank 210 To do this.

The raw material mixture liquid evenly mixed as described above is distributed and supplied to the raw material acceleration part 300 provided in two through the discharge port 230 at the lower portion thereof.

The raw material accelerating unit 300 is shown in more detail in Figure 4 of the accompanying drawings, which is provided with a pair of left and right identical structures facing each other to produce a raw material mixture solution supplied from the raw material mixing unit 200 It is to provide a function to spray each of the unit 500.

The raw material accelerator 300 has only the same structure as each other provided in a pair will be described only one.

The raw material acceleration part 300 includes a cylinder 310 having a long cylindrical shape, and a motor for moving the piston 320 and the piston 320 to compress the raw material mixture to move in and out of the cylinder 310. 330, the inlet 340 is connected to the one side of the front of the cylinder 310, the discharge port 350 is discharged at a high speed to discharge the raw material mixture pressurized in the cylinder 310 at the front end pipe 351 is provided with a connection.

At this time, the check valve 360 is provided on the inlet 340 and the discharge port 350 so as to smoothly compress the raw material mixture to be introduced and discharged.

The cylinder 310 is a raw material mixture is introduced to provide a function that is compressed by the piston 320, the piston 320 is a rotary motion of the motor 330 is converted into a linear motion through the crankshaft to move forward and backward cylinder It is compressed within 310.

That is, when the piston 320 is moved forward by the rotational force of the motor 330, the raw material mixture flowing through the inlet 340 is strongly compressed and discharged through the discharge port 350 of the front end, on the contrary, the reverse operation When the discharge port 350 is closed by the check valve 360, the raw material mixture is repeatedly injected into the inlet 340 to discharge the raw material mixture at high pressure and high speed.

In addition, a separate pulse generating unit 400 is installed as a pipe 351 at the front end of the discharge port 350, the pulse generating unit 400 is shown in more detail in Figure 5 of the accompanying drawings.

This is the motor 410 for generating the rotational power, the rotating body 420 is rotated by receiving the power of the motor 410 to the pulley and the like, the shaft is coupled to the rotating body 420 to convert the rotational power into linear motion It consists of a crank shaft 430 and a piston 450 that is moved back and forth in the cylinder 440 by the power of the crank shaft 430, the cylinder 440 is provided in communication with the pipe 351.

Therefore, the rotational power generated by the motor 410 is converted into a linear motion by the rotor 420 and the crankshaft 430 is transmitted to the piston 450 in the pulse generator cylinder 440 to repeat the compression and expansion. .

That is, by increasing or decreasing the discharge pressure of the raw material mixture passed into the pipe 351 as the piston 450 moves forward and backward, acceleration and deceleration are repeated with a constant pulse, thereby improving efficiency due to mutual collision.

The raw material collision manufacturing unit 500 is formed with a manufacturing cylinder 510 having a manufacturing space sealed inside the cylindrical shape as shown in Figures 6 and 7 of the drawings, on both sides of the manufacturing cylinder 510 A pair of

injection nozzles

520 and 530 having different apertures are installed to face each other in a straight line, and a discharge port 540 through which the raw material mixture made of fine particles is discharged from the lower part of the manufacturing container 510. Is installed.

In addition, the discharge port 540 is connected to the recovery pipe 542 which is controlled by the valve 541 and the raw material mixture is recovered back to the raw material mixing unit 200, and at the same time the raw material mixture is completed, the raw material separating unit A discharge pipe 543 for sending to 600 is provided with a connection.

The manufacturing container 510 is configured to have a substantially cylindrical structure and has a sealed structure, and a discharge port 540 is installed at the bottom thereof, and at the same time, two

injection nozzles

520 and 530 face each other. Has a structure to be installed.

The injection nozzles 520 and 530 have different apertures and are connected to the outlets 350 of the two raw material acceleration units 300 as pipes, respectively, and the injection nozzles 520 having a large aperture have a diameter. It is preferable to have a size of 1.5-2 times that of the small jet nozzle 530.

* If the two

injection nozzles

520 and 530 have the same aperture, if the two injection nozzles eject the same amount at the time when the raw material mixture is ejected at a high pressure, the acceleration of each other may be canceled at the collision point. Therefore, to prevent this, the diameters of the

injection nozzles

520 and 530 are different from each other.

Therefore, as shown in FIGS. 8 and 9 of the accompanying drawings, the droplet mixture jetted from the small-bore injection nozzle 530 collides while passing through a large space of the droplet mixture jetted from the large-bore injection nozzle 520. However, since the droplets of the raw material mixture sprayed from the large injection nozzle 520 wrap around the raw material droplets injected from the small injection nozzle 530, the collision may be more ideal.

In addition, the holes of the

injection nozzles

520 and 530 are provided in a straight line so that the raw material mixture sprayed at high speed can be sprayed in a straight line without being diffused.

Most nozzle types used for high-speed collisions induce jet expansion by making the inlet wider and the outlet narrower than the inlet, but this method has a rapid expansion effect, but the straightness is significantly reduced, resulting in penetration of solution droplets of different sizes. It can weaken the collision effect.

Therefore, in the present invention, in order to maximize the effect of the collision, the raw material mixtures sprayed at both sides of the

spray nozzles

520 and 530 simultaneously collide with each other precisely at the intermediate point of the

spray nozzles

520 and 530. The holes are provided in a straight line.

In this case, in order to prevent the collision speed from dropping by the pressure prevailing in the manufacturing vessel 510 through the operation in the collision device, the interlocking control method that allows the optimum collision to occur by interlocking the injection and discharge of the raw material mixture at the time of collision. Designed to be a continuous circulation reaction will be performed automatically.

On the other hand, the outer surface of the

injection nozzle

520, 530 is provided with a cooling means 550, heating means 560, adjusting means 570 as shown in FIG.

The cooling means 550 is a general known configuration, but is not shown in detail in the drawings, but when the temperature rises excessively by the raw material mixture injected through the injection nozzle, the cooling water is circulated to cool the tubular body of the injection nozzle to a predetermined temperature. One configuration.

In addition, the heating means 560 is a concept opposite to the above-described cooling means 550 is configured to maintain a proper temperature at all times by heating the heater in connection with the electrical device when the temperature is too low.

The cooling means 550 and the heating means 560 may use the same method as usual, for example, the cooling means 550 may circulate the cooling water or use a refrigerant cycle, the heating means 560 is also As usual, by heating the heater wires therein, the proper temperature may be maintained at all times.

And, the adjusting means 570 is to adjust the position adjustment using the laser and the distance of the injection nozzles (520, 530), which also has a conventional structure as shown in Figure 9 of the drawing four front The sensor 571 may be provided to adjust the distance between the two

injection nozzles

520 and 530.

The raw material separating part 600 receives the raw material mixture prepared by the collision method from the raw material collision producing part 500 to separate the raw material particles prepared in water and nano size.

The raw material separator 600 may use a separator having a suitable structure such as a centrifugal separator or a filter separator as usual, and since the raw material particles to be separated are used in industry, and water is not contaminated. It can be used in many other ways.

Therefore, when looking at the operating state of the present invention configured as described above, if you want to produce a raw material particles, such as metal, ceramic, organic polymers of a certain size of particles to the nano-size microparticles, mixing the raw material particles according to the water To the feed hopper 110 of the raw material supply unit 100.

In this case, the raw material particles are generally in a powder state and are supplied at a ratio that can be sufficiently mixed in the water in consideration of their type and size, and the water and raw material particles may be separately added or mixed as separate containers first. Can be.

The water and the raw material particles supplied to the raw material supply unit 100 are introduced into the tank 210 through the inlet 211 of the raw material mixing unit 200, and at the same time, the stirring blade 221 while the motor 220 is operated. As) rotates, water and raw particles are evenly mixed.

When the mixing is made properly, the valve 231 of the outlet 230 is opened and the raw material mixture is sent to the next step, the raw material accelerator 300.

The raw material accelerating unit 300 is distributed to both sides through the discharge port 230 to form a pair of the same two, the raw material accelerating unit 300 through the inlet 340 as shown in the accompanying drawings When the raw material mixture is introduced, the piston 320 moves forward and backward as the motor 330 operates to pressurize the raw material mixture injected into the cylinder 310. Accordingly, the raw material mixture pressurized at high pressure causes the front discharge port 350 to be pressed. Is discharged to the next stage.

When the piston 320 is backward, the discharge port 350 is closed by the check valve 360 and at the same time the check valve 360 of the inlet 340 is opened, the raw material mixture is introduced into the cylinder 310, On the contrary, when the piston 320 is advanced, the inlet 340 is closed and the discharge port 350 is opened, so that the pressurized raw material mixture is discharged to the pulse generator 400 through the pipe 351 through the discharge port 350.

In the pulse generator 400, the rotational power of the motor 410 is converted into linear power via the rotor 420 and the crankshaft 430 to advance and retract the piston 450 in the cylinder 440. Acceleration and deceleration of the raw material mixture passing through the pipe 351 through the discharge port 350 are repeated.

That is, when the piston 450 moves forward, the piston 450 is added as much as the capacity in the cylinder 440 pushed by the piston 450 rather than the pressure of the raw material mixture passing through the pipe 351, thereby causing a sudden compression phenomenon. The raw material mixture liquid that is forcibly progressed through the pipe 351 by the accelerator 300 generates instantaneous thrust (pik) according to rapid acceleration.

On the contrary, when the piston 450 is retracted, the raw material mixture that has passed through the pipe 351 is sucked into the cylinder 440 instantaneously, and thus a deceleration loss phenomenon occurs as much as the amount of water sucked in. The inside of the 351 is periodically a process of compression and expansion occurs to cause a collision by the pulses in the injection nozzles (520, 530) of both sides of the raw material collision manufacturing unit 500, which is the next step.

Subsequently, the raw material mixture passing through the pipe 351 is sprayed into the manufacturing cylinder 510 through both

injection nozzles

520 and 530 of the raw material collision manufacturing unit 500 which is the next step, and both

injection nozzles

520 and 530. ), The raw material mixture is injected at high pressure and high speed and with a constant pulse to the front in the center.

That is, the raw material mixtures A sprayed through the

respective injection nozzles

520 and 530 having different apertures collide with each other in front, and the raw material mixtures A thus collided are shown in FIGS. 8 and FIG. As shown in FIG. 9, a frontal collision occurs and pulverizes as the raw material mixture A injected into the small injection nozzle 530 is injected into the raw material mixture A injected through the large injection nozzle 520.

As described above, the raw material mixture (A) in which water (H) and raw material particles (P) are mixed is strongly frontally collided with the raw material particles (P) by frontal collision with each other, and is pulverized into fine particles. Discharged through the discharge port 540 in the barrel 510, the discharged fine particles are selected and discharged to the recovery pipe 542 or discharge pipe 543 by the operation of the valve 541.

That is, if the production is not made of the fine particles of the desired size by the primary manufacturing process, it is recovered to the recovery pipe 542 and circulated to the recovery port 213 of the raw material mixing unit 200 to undergo a repeated manufacturing process do.

As described above, the work according to the present invention can be completed by continuously performing a batch-type operation continuously until a desired nano-size microparticle is obtained. By the operation of the valve 541 is sent to the raw material separator 600, which is the next process through the discharge pipe (543).

The raw material separation unit 600 separates the raw material particles (P) of water (H) and fine particles in a number of ways as usual, and the separated raw material particles (P) are utilized as desired and water (H). ) Can be used in many other ways.

On the other hand, the present invention as described above, as the raw material mixture is injected in a constant pulse through the injection nozzle in a pressurized state at high pressure, depending on the raw material particles to be produced, the temperature change may be severely generated by cooling means for controlling this 550, the heating means 560 may be installed and used, and various adjustment means 570 of a known configuration may also be used to adjust the spacing or position of both injection nozzles.
