FIG. 4 and FIG. 5 are schematic diagrams showing how a rare substance is separated and extracted from fine particles flowing into a pipe body.

(overall structure)
As shown in FIG. 1 and FIG. 2, the specific substance extraction device 100 includes a device main body 1 that can float on the sea, a power generation device 2 that uses natural energy installed in the device main body 1 as a power source, and in seawater. A pipe main body 20 disposed in the fluid flow path R and a branch pipe 30 extending outward from a part of a side wall 25 in the pipe main body 20 are provided. Further, in the boundary region between the branch pipe 30 and the pipe main body 20, ultrasonic vibrators 22a and 22b (concentration means) for irradiating and concentrating the fine particles with ultrasonic waves, and branching the concentrated fine particles by applying an electric field. Separation guiding means 60 for guiding to the pipe 30 side and recovery means 70 for collecting rare substances separated and guided on the downstream side of the branch pipe 30 to collect rare substances are configured.

  In addition, about the process which measures and detects the microparticles | fine-particles X with the pipe main body 20 arrange | positioned in the fluid flow path R, the technique of the microparticles | fine-particles measuring apparatus disclosed by Unexamined-Japanese-Patent No. 6-241977 (patent document 2) is employ | adopted. Therefore, the following description will be made with reference to JP-A-6-241977.

  In order to concentrate the fine particles in the fluid, the fine particle measuring apparatus concentrates the fine particles using ultrasonic waves. That is, an ultrasonic standing wave is formed in the liquid flow path, and the fine particles are concentrated at the position of the node, or a plurality of ultrasonic traveling waves are overlapped to collect the fine particles at a specific position. To separate.

  Next, a method for collecting fine particles using ultrasonic waves will be described. In the present invention, an agglomeration mechanism using standing waves or traveling waves mainly using radiation pressure is used.

When the ultrasonic wave is a standing wave, the force Fcs exerted on the fine particles by the ultrasonic wave is expressed by the following equation.

  k is the wave number in the solution, φ is (fine particle density) / (solvent density), β is the elastic modulus of the fine particle, β0 is the elastic modulus of the solution, ρ is the density of the solution, a is the diameter of the fine particle, Us is The amount to define. Us2 = (2 I / ρC) × 10 7 (cm 2 / S 2), where I is the power density (W / cm 2), C is the speed of sound in the solvent, y is the position in the direction of ultrasonic travel, and standing wave at the center of the flow cell Let y = 0 be the position of the node. The fine particles are concentrated at the position of the node (y = 0) by Fcs.

  When the ultrasonic wave is a traveling wave, the force Fct exerted on the fine particles is expressed by the following equation.

  FIG. 14 is a view showing the measurement / detection processing of the fine particles, FIG. 15 is a cross-sectional view showing the region where the fine particles are concentrated, and (a) shows a case where an ultrasonic transducer is used on the opposite side surface of the flow path. FIG. 4B is a diagram showing a case where an ultrasonic transducer is used on the four side surfaces of the flow path.

  The apparatus of the embodiment shown in FIG. 14 is composed of a part for concentrating fine particles by ultrasonic waves. In the part where the fine particles are concentrated, a pair of ultrasonic transducers 5 are attached to the outer surface of the flow cell 4 so as to face each other, and the ultrasonic transducer 5 is used to form a node at the center of the flow cell 4. Generate standing ultrasonic waves. Since the sound velocity in pure water is 1500 m / s at a water temperature of 25 degrees, the ultrasonic transducer 5 is used to generate a standing wave having one node in the flow cell 4 having a width of 1 mm. What is necessary is just to vibrate with a frequency of 750 kHz.

  By irradiating ultrasonic waves with an ultrasonic intensity of 6.0 to 9.0 mW per square centimeter, the fine particles in the flow cell 4 are caused to react with each other by mechanical action based on the sound pressure of the ultrasonic waves and the collision between the particles. It can be concentrated at the position of the node of the standing wave at a speed according to the shape of the fine particles and the acoustic impedance. It is desirable to keep the output value of the ultrasonic wave within a range where cavitation does not occur.

  In this embodiment, there is one node of the ultrasonic standing wave, but it is possible to form a standing wave having a plurality of nodes as required. In this embodiment, a pair of opposing ultrasonic transducers 5 is used on the side surface of the flow path, but the ultrasonic transducers 5 may be used on the four side surfaces of the flow path. The difference in the concentration state in these cases is as shown in FIGS. 15A and 15B, respectively, and the ultrasonic transducer 5 is provided on the opposite side surface of the flow cell 4 as shown in FIG. 15A. Instead, the concentration rate of the fine particles is higher when it is provided on the four side surfaces of the flow cell 4 as shown in FIG.

Next, the rare substance recovery process of the present invention will be described with reference to FIGS.
FIG. 3 is a flowchart illustrating each process of the specific substance extraction apparatus 100, and FIGS. 4 and 5 show changes in fine particles. Note that “rare substances” are uranium, palladium, gold, and the like in underwater water.

  As shown in these drawings, the ultrasonic transducers 22a and 22b in which the fine particles X in the pipe main body 20 are arranged to face the side wall 25 of the main body pipe 20 irradiate the fine particles X with ultrasonic waves (S101). The separation guiding means 60 applies an electric field to the fine particles X concentrated by the irradiation of ultrasonic waves (S102).

The fine particles X having a large dispersoid mass are guided to the branch pipe 30 side by the separation guiding means 60 (S103). On the other hand, the fine particles having a small dispersoid mass are not guided to the branch pipe 30 side but are directly guided to the main body pipe 20 (S104) and discharged from the opening on the downstream side of the main body pipe (S105).

  The separation induction means 60 has a function of applying an electric field to the inside of the branch pipe 30 to separate and induce the fine particles X, and includes at least an electrode connected to a DC power source, a solution containing a substance to be electrophoresed, and the power source. ing. That is, by applying a voltage perpendicular to the flow of the fine particles, the fine particles are migrated perpendicular to the flow, and the fine particles are guided to the branch pipe 30. If it does in this way, although the main body pipe 20 is the density | concentration as low as seawater, the branch pipe 30 will become a density | concentration higher than seawater.

Then, the particulate X2 guided to the branch pipe 30 side by the separation guide means 60 is collected and collected as a rare substance by the collection means 70 disposed in the branch pipe 30 (S106).
This collection means 70 is formed of a so-called semipermeable membrane. The “semipermeable membrane” is, for example, a porous membrane of regenerated cellulose (cellophane), acetylcellulose, polyacrylonitrile, Teflon (registered trademark) or polysulfone. Since the semipermeable membrane is a membrane that allows only molecules or ions having a certain size or less to permeate, the collection of the rare substance can be facilitated by forming the collection means 70 with the semipermeable membrane.

  In a system of a solute that does not permeate the semipermeable membrane and a solvent that exhibits permeability, when two concentrations of the solution are contacted via the semipermeable membrane, an osmotic pressure is generated and only the solvent permeates. In the case of an ideal semipermeable membrane, the osmotic pressure is proportional to the molar concentration of the solution, and it is possible to measure the mass of a dispersoid such as a polymer using this principle.

  Therefore, the fine particles X2 recovered by the recovery means 70 can be recovered as a desired rare substance. As a result, the target rare substance can be efficiently separated and extracted even in low-concentration water.

  The collecting means 70 can also be formed as an adsorbing substance. The “adsorbing substance” is, for example, an ion adsorbing substance that recovers uranium or the like.

Note that natural energy is used as a power source for operating the specific substance extraction apparatus. Natural energy may be any of sunlight, hydraulic power, wind power, etc., but sunlight is desirable in consideration of the place of use. In addition to natural energy, a predetermined battery can be loaded on the apparatus, and the entire apparatus can be operated as power assistance.
In particular, in the sea, since a flow of water current is generated, it is preferable to operate using tidal power.

(Second embodiment)
Next, a second embodiment of the present invention will be described with reference to FIGS. The specific substance extraction device 200 of the second embodiment is configured to increase the number of pipes that further branch from the branch pipe 30 of the first embodiment described above to separate the fine particles.

  That is, in addition to the main body pipe 20, the branch pipe 30, and the separation guiding means 60 shown in the first embodiment, the second branch pipe 40 extended outward from a part of the side wall 35 of the branch pipe 30, and its In the boundary region between the second branch pipe 40 and the branch pipe 30, ultrasonic waves 22c and 22d (second concentration means) for irradiating and concentrating the target fine particles X with ultrasonic waves, and applying an electric field, The second separation guiding means 60b for guiding the concentrated fine particles X2 to the second branch pipe 40 side, and the second separation guiding means 60b include a second collection means 70b capable of collecting rare substances. .

  As shown in FIGS. 6 to 11, the ultrasonic transducers 22a and 22b irradiate the fine particles X in the pipe body 20 with ultrasonic waves (S201). The separation inducing means 60 applies an electric field to the fine particles X concentrated by the irradiation of ultrasonic waves (S202). The fine particles X having a large dispersoid mass are guided to the branch pipe 30 side by the separation guiding means 60 (S203). On the other hand, the fine particles having a small dispersoid mass are not guided to the branch pipe 30 side but are directly guided to the main body pipe 20 (S204) and discharged from the opening on the downstream side of the main body pipe (S205).

Subsequently, as shown in FIG. 8, the fine particles X2 and the fine particles X3 guided to the branch pipe 30 side are the second ultrasonic transducers 22c and 22d disposed on the side wall 35 of the branch pipe 30. X3 is irradiated with ultrasonic waves (S206). The second separation guiding means 60b applies an electric field to the fine particles X2 and the fine particles X3 concentrated by the ultrasonic irradiation (S207).

Here too, the fine particles X3 having a large dispersoid mass are guided to the second branch pipe 40 side by the second separation guiding means 60b (S208). On the other hand, fine particles having a small dispersoid mass are guided to the branch pipe 30 (S209). Here, it discharges from the opening of the downstream side of the branch pipe 30, or collect | recovers the microparticles | fine-particles X2 as a scarce resource (S210).
Further, as shown in FIG. 11, the fine particles X3 guided to the second branch pipe 40 are collected and collected as a rare substance by the second collection means 70b (S211).

  The second separation induction unit 60b is the same as the separation induction unit 60 described above in that it includes at least a DC power source, a solution containing a substance to be electrophoresed, and an electrode connected to the power source. That is, by applying a voltage perpendicular to the flow of the fine particles, the fine particles are migrated perpendicular to the flow, and the fine particles are guided to the second branch pipe 40 side. In this way, the second branch pipe 40 has a higher concentration than the branch pipe.

  In the present embodiment, the locations where the fine particles X are separated and guided are set in two stages: the main body pipe 20 and the branch pipe 30, and the branch pipe 30 and the second branch pipe 40. In the fine particles X2 guided to the branch pipe 30, it is possible to accumulate desired rare substances such as uranium and gold, but there is a possibility that they cannot be recovered. On the other hand, in the specific substance extraction device 200, the fine particles X2 are further separated and extracted and guided to the second branch pipe 40, whereby the desired rare substance X2 is reliably collected and collected by increasing the concentration. Can do.

  In addition, as shown in FIG. 12, the 3rd branch pipe 50 further branched toward the downstream from the side wall of the 2nd branch pipe 40 can also be provided. Further, as shown in FIG. 13, a fourth branch pipe 55 that is further branched downstream from the side wall of the third branch pipe 50 can be provided. The third branch pipe 50 and the fourth branch pipe 55 are respectively provided with an ultrasonic vibrator and a separation guiding means, and the third branch pipe 50 is superposed on the fine particles guided from the second branch pipe 40. The acoustic vibrator emits ultrasonic waves, and an electric field is applied by the separation guiding means. The fine particles separated and guided to the fourth branch pipe 55 side are again irradiated with ultrasonic waves by the concentration means and applied with an electric field by the separation induction means.

  That is, the concentration of fine particles increases as the branch pipe is branched in multiple stages and branched to the lower layer pipe. Note that the number of branch pipes to be set differs depending on the dispersoid mass of the rare substance to be collected.

Although the specific substance extraction apparatus according to the present invention describes that a rare substance is separated and recovered from fine particles in seawater, it can also be applied to lake water such as a volcanic lake. Depending on the volcanic lake, it may be possible that more rare substances are contained than seawater, so that the recovery operation can be carried out efficiently.
Moreover, although this embodiment has been described for the purpose of collecting rare substances, it can also be applied to collecting harmful substances in seawater and lake water. In this case, the separation inducing means may be changed to a concentration that can induce harmful substances. If it does in this way, it will contribute to various pollution measures by purifying the water.
