Description

Charged water particle dispersion device (1) Field of invention

The invention relates to a charged water particle dispersing device, which is used for removing dust floating in the air or suppressing the generation of dust.

Background of the invention

For example, in tunnel construction or demolition work, it is very important to suppress the generation of dust and to effectively remove the generated dust from the air. In the past, the excavation work or the demolition work was performed while sprinkling water to suppress the generation of dust, and the generated dust was removed.

On the other hand, the proposal has been put into practical use (for example, refer to Patent Document 1 and Patent Document 2), in which mist-like water is sprayed (sprayed) from a discharge nozzle, and fine water particles are attached to floating dust in the air. The dust is dropped together with the water particles, thereby being removed from the air. In this method, dust can be effectively removed with a small amount of water as compared with the case of simply sprinkling water.

In addition, a method of ejecting (spraying) charged water particles to remove dust has been proposed (see, for example, Patent Document 3 and Patent Document 4). In this method, by charging the water particles, the charged water particles can be electrically adsorbed to the dust, and the dust can be removed more efficiently.

Summary of invention

However, in the conventional method of ejecting the charged water particles and capturing the dust, the charged water particles are fine particles having a particle diameter of several tens to several hundreds of μm. Therefore, even if the water pressure is to be increased, the charged water particles are ejected from the discharge nozzle. However, due to the air resistance of the space, the air will be stalled immediately after the ejection, and it is impossible to reach the far side. For the distance to be reached, for example, the charged water particles can be dispersed only in a range of about 1 m around the discharge nozzle. Therefore, when excavating the tunnel site, etc., it is impossible to remove the dust floating in a wide range of air, or to use a source of dust generated in a distant place (a target for suppressing dust generation) to wet the charged water particles to suppress the generation of dust. Applicable questions.

Further, in the above-described conventional method, in order to charge the water particles or to ionize the air (the ions are attached to the water particles), it is extremely difficult to securely discharge the conditions by discharge, for example, for a long period of time, for example, There is a possibility of leakage, and for example, there is a problem in design that is difficult to ensure grounding, and there is also a safety problem in handling.

The present invention has in view of the above facts, and an object thereof is to provide a charged water particle dispersing device which can solve problems in design and safety. The generated charged water particles are transported in a desired direction and in a distant direction to remove a large range of dust, or to infiltrate a distant dust to suppress the generation of the dust itself.

In order to achieve the above object, the present invention provides the following means.

The charged water particle dispersing device of the present invention is configured to have an air flow generating mechanism that generates an air flow that flows in one direction, and a charged water particle generating mechanism that generates water particles and charges the water particles by induced charging to generate charged water. The particles are ejected, and the charged water particles generated by the charged water particle generating means and discharged are carried by the air flow generated by the air flow generating means, and are transported in the one direction.

In the present invention, the air flow generated by the air flow generating means can transport (transfer) the charged water particles (charged water particle group) which have been generated and ejected by the charged water particle generating means in one direction, and can take the charged water particles into the air. The flow is delivered to a distant place. Further, even when the charged water particles are transported by the air flow as described above, by generating the charged water particles of the same polarity, the charged water particles are electrically repelled and do not stick together, thereby maintaining the desired state. The charged state of the specific charge amount is far away. Further, since the water particles are charged by the induced charging method, it is safer than the conventional charging method with the discharge.

Thereby, the dust floating in the air in the desired direction can be electrically captured and removed by the flow direction of the air flow, that is, the direction in which the air flow is directed, and the charged water particles can be transferred by the air flow. Going far away, it can remove a wide range of floating dust.

Further, when the dust particles are generated in a direction toward the dust generation source and the like, and the charged water particles are transported by the air flow, the charged water particles are blown to the distant dust generation suppression target, and the dust generation suppression target is generated. Wet with charged water particles. In addition, when the air flow is blown to the dust generation suppression target, the charged water particles contained in the air flow reach the vicinity of the dust suppression target, and the back is exerted by the Coulomb force acting between the dust suppression target. The side is also pulled up and adhered to the object to suppress the dust generation, and the back side of the object to be suppressed can be generated by the dust particles that are carried by the air flow and are not easily contacted by the dust. As a result, if the air flow is directed to the dust generation target such as the dust generation source, the charged water particles can be used to suppress the generation of the dust by the wetness of the dust generation target. In addition, by the action of the Coulomb force and/or the gradient force exerted between the charged water particles and the dust (particles), the dust can be captured, and the dust generated and scattered by the dust suppression object can be greatly suppressed. .

Further, in the charged water particle dispersing device of the present invention, it is preferable that the charged water particle generating means is disposed such that a discharge central axis of the charged water particles ejected from the charged water particle generating means can be from the outer side of the air flow and the air flow The airflow center axis intersects.

The air flow flowing in one direction can be formed around the charged water particles generated and discharged by the charged water particle generating means, thereby suppressing the escape of the charged water particles and reliably carrying the charged water particles in the air flow and transporting them in one direction.

Further, in the charged water particle dispersing device of the present invention, the charged water particle generating means is preferably configured to have a discharge nozzle portion that ejects water supplied by pressurization to generate the water particles, and an induced electrode portion that is formed by applying a predetermined voltage. The predetermined electric field is such that the water particles generated by the discharge nozzle portion are charged by the electric field as the charged water particles, and the water-side electrode portion is given a reference potential of a voltage applied to the induction electrode portion.

In the present invention, the water particles generated by the discharge nozzle portion of the charged water particle generating means can be charged by the electric field formed by the induction electrode portion, whereby the charged water particles can be easily and surely generated and discharged.

In the case of the plurality of charged water particle generating means, the water-based electrode portion to which the reference potential is applied is used as a common electrode in the plurality of charged water particle generating means, but as described above, it is shared by the plurality of charged water particle generating means. In the water-side electrode portion, the specific charge of the charged water particles (charged water particle group) generated by each of the charged water particle generating means is lowered.

On the other hand, according to the present invention, when each of the charged water particle generating means is configured to have the water-side electrode portion, the charged water particles having a desired specific charge can be surely generated, whereby the air can be surely and efficiently removed.

In the present invention, the charged water particle generating means is disposed while the pressurized water is supplied and the water is split into water particles, and the charged splitting electrification part is disposed in front of the air flow discharge port of the air flow generating means. On the side (the downstream side in the flow direction of the air flow), the charged water particles charged in the split charging portion are not carried by the air flow, and for example, it is possible to prevent the air flow in the air flow generating mechanism from being electrically adsorbed. Thereby, the charged water particles generated and discharged by the charged water particle generating means can be reliably carried by the air flow and transported in a distance, and the dust floating in the air can be removed more reliably and effectively, and the generation of dust can be suppressed.

The effect of dust generation. In addition, when the particle size of the generated water particles is larger than 300 μm, the charged water particle generating means charges and generates water particles, and the number of charged water particles to be discharged is reduced, and it is a matter of course that the dust cannot be sufficiently removed to suppress the dust.

Thereby, the discharge nozzle 14 can be fixed and mounted at a predetermined position of the front end portion of the water circulation hole 16 to be detachable.

Next, the three electrode fixing portions 28 are attached to the second flow path forming member 13 . At this time, the electrode main body portion 9 of the induction electrode portion 7 in a state in which the induction electrode insertion hole 27 of the second flow path forming member 13 is inserted into the connection portion 10 is engaged with the other end of each electrode fixing portion 28.

With this, The induction electrode portion 7 is fixed and supported by the three electrode fixing portions 28, and the induction electrode portion 7 is attached as described above, and the annular electrode main portion 9 is disposed at a predetermined interval with respect to the discharge nozzle 14, and its center position is provided. It is disposed coaxially with the nozzle hole 14a of the discharge nozzle 14 and the water circulation hole 16.

Further, a pipe from a pump unit (not shown) is connected to the pipe connection portion 17 of the first flow path forming member 12. Further, the ground cable is connected to the water-side electrode portion 8 to be grounded, and the voltage application cable (voltage application wire) 32 is connected to the conductive member (electrode 7a) of the connection portion 10 of the induction electrode portion 7, and the voltage is applied. The cable 32 connects the induction electrode portion 7 to the power source 33 (see Fig. 5).

In the charged water particle generating unit 2 of the present embodiment, which is configured as described above, when the pump unit is driven, the water W2 is pressurized and supplied to the discharge nozzle unit 6 through the pipe, for example, at a pressure of about 1 MPa. The hole 16 is ejected from the nozzle hole 14a of the discharge nozzle 14.

In addition, when the water-side electrode portion 8 is grounded by the grounding cable, and a predetermined voltage of a direct current (AC or pulse) of, for example, several kV to several tens of kV is applied to the induction electrode portion 7, the electrode body portion 9 is formed. A predetermined external electric field is formed around. In addition, the water W2 ejected from the nozzle hole 14a is split and separated by the split charging unit S to generate water particles (water particle group) W1, and the water particle W1 is charged by the electric field as charged water particles (charged water particle group). W1 is ejected. Incidentally, when a direct current voltage is applied to the induction electrode portion 7, the charged charged water particles W1 are generated by the charge of either of the positive charge and the negative charge according to the polarity of the induced electrode portion 7. Further, when a voltage is applied by an alternating current or a pulse, the positive polarity can be selectively used according to the polarity of the induced electrode portion 7 that is alternately switched. Charged or negatively charged to generate charged charged water particles W1. That is, the charged water particles W1 that are positively charged and the charged water particles W1 that are negatively charged can be appropriately and selectively generated.

Further, at this time, in the charged water particle generating unit 2 of the present embodiment, the voltage applied when the charged water particles W1 are generated is in the range of -20 kV to 20 kV. The applied voltage may be a predetermined constant voltage in the range of -20 kV to 20 kV, or may be varied in the range of -20 kV to 20 kV. Further, as described above, when the applied voltage is in the range of -20 kV to 20 kV, corona discharge can be prevented, and the generation of the charged water particles W1 can be ensured.

Further, in the charged water particle generating unit 2 of the present embodiment, when the particle diameter of the water particle W1 generated by the charged water particle generating unit 2 is smaller than 100 μm, the charged water particle W1 generated by charging the water particle W1 is generated. Will become easy to evaporate. In addition, when the particle diameter of the generated water particle W1 is larger than 300 μm, the number of charged water particles W1 generated by the charged water particle generating means 2 by charging the water particle W1 and being discharged is reduced. Further, in the charged water particle generating unit 2 of the present embodiment, when the water particles W1 having a particle diameter of 100 to 300 μm are formed, and the water W2 is pressurized from the pump unit by a pressure of about 1 Mpa, Charged water particles W1 having a particle diameter of about 200 μm were produced.

Further, in the charged water particle generating unit 2 of the present embodiment, charged water particles W1 of 1 to 2 L/min are generated. Here, FIG. 6 shows the relationship between the amount of water (the amount of water supplied to the charged water particle generating means 2) of the charged water particles W1 of the charged water particle generating means 2 and the specific charge of the charged charged water particles W1. And, as shown in FIG. 6, when the amount of water to be dispersed is When it is 1 to 2 L/min, it is possible to ensure a certain amount of water to be dispersed, and further, it is confirmed that the specific charge of the generated charged water particle W1 becomes 0.1 mC/kg or more, and the larger specific charge can be used. The charged water particles W1 are surely generated.

Further, in the charged water particle generating unit 2 of the present embodiment, the induction electrode portion 7 is formed by insulatingly coating the electrode 7a with the insulating material 7b. Therefore, water does not come into contact with the induction electrode portion 7 and is short-circuited or charged. In the case of generation, safety can be ensured, and generation of charged water particles W1 can be appropriately performed.

In addition, in Table 1, the case where the discharge electrode flow rate (distributed water amount) is 1 L/min, the applied voltage applied to the induction electrode portion 7 is +5 kV, and the induction electrode portion 7 is formed without providing an insulating coating, and various insulations are used. The case where the material 7b is insulated and coated to form the induction electrode portion 7 shows the result of measuring the specific charge of the charged water particle W1. From the results, it can be confirmed that when the polyamide resin (nylon: registered trademark) or the polyethylene resin is used as the insulating material 7b, the specific charge is significantly larger than the case where the insulating coating is not provided. The ground becomes smaller.

On the other hand, it was confirmed that polyvinyl chloride resin, polyphenylene sulfide resin (PPS), urethane resin, polytetrafluoroethylene resin, polychlorotrifluoroethylene resin, aluminum ceramic, and glass crucible were used as the insulating material. When 7b is used, the charged water particles W1 are generated in the same manner as in the case where the insulating coating is not provided, or the specific charge above it. Thus, in the charged water particle generating mechanism 2 of the present embodiment, the polyvinyl chloride resin, the polyphenylene sulfide resin (PPS), the urethane resin, the polytetrafluoroethylene resin, and the polychlorotrifluorocarbon are used. At least one of vinyl, aluminum ceramic, and glass crucible The induction electrode portion 7 is formed as the insulating material 7b, whereby short-circuiting or charge neutralization can be prevented, and generation of the charged water particles W1 can be appropriately performed.

Next, as shown in Fig. 1 and Fig. 2, in the charged water particle dispersing device A of the present embodiment, the wind tunnel 3 of the blower, which is one air flow generating means 1, is configured to generate a plurality of charged water particles as described above. The mechanism 2 is mounted as a separable body using a mounting mold (mounting member) 35, respectively.

Moreover, as shown in FIG. 1, the charged water particle generating means 2 is attached to the airflow generating means 1, and the charged water particles W1 generated and discharged by the charged water particle generating means 2 are carried by the air generated by the airflow generating means 1. The flow R is (rolled in) and conveyed (transferred) in the direction of flow of the air flow R, that is, in one direction T.

Specifically, as shown in FIG. 1 and FIG. 2, in the present embodiment, the discharge center axis O4 of the charged water particles W1 ejected from each of the charged water particle generating mechanisms 2 and the flow center of the air flow R flowing in the one direction T A point P on the axis O1 intersects, and the plurality of charged water particle generating mechanisms 2 are disposed outside the air flow R. At this time, the intersection angle takes into consideration the discharge speed of the charged water particles W1, the discharge diffusion angle, the flow velocity of the air flow R, and the like, so that the charged charged water particles W1 can be satisfactorily wound into the air flow R.

Further, in the present embodiment, the plurality of charged water particle generating mechanisms 2 are arranged at equal intervals in the circumferential direction around the flow center axis O1 of the air flow generating mechanism 1. Further, the plurality of charged water particle generating mechanisms 2 are disposed on the same plane H orthogonal to the one direction T, and the split charging unit S that splits and separates the water particles W1 discharged from the nozzle holes 14a is arranged to be discharged. The air flow discharge port 3a of the air flow generation mechanism 1 of the air flow R is provided on the more front side in the direction T (the downstream side in the flow direction T of the air flow R).

In the charged water particle dispersing device A of the present embodiment, the mounting die 35 is attached to the predetermined position of the wind tunnel 3 of the airflow generating means 1, and as described above, the plurality of charged water particle generating means 2 are automatically arranged to The discharge center axis O4 of the charged water particles W1 intersects at a point on the flow center axis O1 of the air flow R, and further becomes equal intervals in the circumferential direction around the flow center axis O1 of the air flow generation mechanism 1, and further, Each of the charged water particle generating mechanisms 2 (the split charging unit S generated by the charged water particles W1) is disposed on the same plane H, and further, the split separating unit S of each charged water particle generating unit 2 is disposed in the specific air flow generating mechanism. The air flow discharge port 3a of 1 is on the front side of the direction T.

Further, in the charged water particle dispersing device A of the present embodiment, a predetermined amount of water W2 is supplied to the plurality of charged water particle generating mechanisms 2 by one pump unit. Further, as shown in FIG. 5, the plurality of charged water particle generating mechanisms 2 are configured to have a pair of water-side electrode portions 8 and an induction electrode portion 7, respectively, and connect the induction electrode portion 7 and the power source of each of the charged water particle generating mechanisms 2 Each of the voltage application cables 32 of 33 is provided with a current limiting mechanism 36.

However, the current limiting mechanism 36 is not particularly limited. For example, as shown in FIG. 5, a current limiting resistor is used, or a transistor or a current limiting circuit using a 3-terminal active device such as a MOSFET, or a current is used. The rectifier diode or the like may be appropriately configured.

As shown in Fig. 1, the charged water particle dispersing device A of the present embodiment, which is configured as described above, drives the air flow generating mechanism by directing the direction of the central axis O1 of the air flow generating means 1 in a desired direction T. The rotary drive unit rotates the rotary wing 4 in a direction T and causes the flowing air flow R to be generated. Further, by the plurality of charged water particle generating mechanisms 2 disposed, the discharge center axis O4 of the charged water particles W1 can cross the flow center axis O1 of the air flow R outside the air flow generating means 1 to generate the charged water particles W1. At the same time and make it squirt. In this manner, the charged water particles W1 generated and discharged by the charged water particle generating means 2 are transferred by the air flow R generated by the air flow generating means 1 in one direction T, and the charged water particles W1 can be transported by the air flow R. To the distance.

Thereby, the dust floating in the air in the desired direction can be captured and removed by the charged water particles W1 by directing the flow direction of the air flow R, that is, the one direction T, in a desired direction. Also, at this time, since the air flow R can be used to charge The water particles W1 are transported to a distant place, so that a large range of floating dust can be removed.

Further, for example, when the dust direction generation source (dust generation suppression target) such as the excavation surface of the tunnel excavation site is directed in one direction T, and the charged water particle W1 is transported by the air flow R, the charged water particle W1 can be blown to The source of the dust in the distance is generated, and the dust generating source is wetted by the charged water particles W1. As a result, as long as the air flow R is directed toward the dust generation source, the dust (particles) of the dust generation source can be captured by the charged water particles W1, and the generation and scattering of the dust from the dust generation source can be suppressed.

Here, it was confirmed that the air flow generation mechanism 1 was subjected to an empirical experiment using a blower having a diameter (the diameter of the air flow discharge port 3a) of 600 mm and a maximum air volume of 200 m 3 /min, and then a wind speed of about 11 m/sec was formed. The air flow R is used to transport the charged water particles W1 to a lateral direction of about 19 m. Further, it was also confirmed that the charged water particles W1 could wet the front side by about 19 m and the width of 2 m.

Therefore, in the charged water particle dispersing device A of the present embodiment, the charged water particles W1 generated by the charged water particle generating means 2 and discharged can be transported in one direction T by the air flow R generated by the air flow generating means 1. By using the air flow R, for example, the charged water particles W1 can be transported to a distance of 10 m or more from the charged water particle generating mechanism 2. Further, as described above, even when the charged water particles W1 are transported by the air flow R, the charged water particles W1 are electrically repelled without generating electrically charged water particles W1 of the same polarity. In the case of sticking together, the charged state of the desired specific charge amount can be maintained until far. Moreover, since the water particles are charged by the induced charging method, it is more complicated than the conventional charging method with the discharge. Safety.

Thereby, the dust floating in the air in the desired direction can be electrically captured and removed by the charged water particle W1 in the direction of the flow of the air flow R, that is, the one direction T, and the air flow R is utilized. By transferring the charged water particles W1 to a distant place, a large range of floating dust can be removed.

Further, when the one direction T is directed toward the dust generation suppression target or the like, and the charged water particles W1 are transported by the air flow R, the charged water particles W1 can be blown to the distant dust generation suppression target, and the object can be suppressed. The dust generation suppressing object is wetted by the charged water particles W1. In addition, when the air flow R is blown to the dust generation suppression target, the charged water particles W1 included in the air flow R reach the vicinity of the vicinity of the dust generation suppression target, and the Coulomb force acting between the dust generation suppression target is utilized. When the back side is also pulled up and attached thereto so as to be coated with dust to suppress the object, the charged water particles W1 carried by the air flow R can be used to wet the air flow R and the dust is not easily contacted. side. By this, if the air flow R is directed to the dust generation target such as the dust generation source, the charged water particles W1 can be used to suppress the generation of the dust by the wetness of the dust generation target. In addition, by the action of the Coulomb force and/or the gradient force exerted between the charged water particles W1 and the dust (particles), the dust can be captured, and the generation of dust from the object of suppression of dust generation can be greatly suppressed and scattered. situation.

Therefore, according to the charged water particle dispersing device A of the present embodiment, the generated charged water particles W1 can be transported in a desired direction and in a distant direction, and a wide range of dust can be removed, or a distant dust suppressing object can be wetted. Inhibit the generation of dust itself. Also, with the dust of the conventional sprinkling water In comparison with the policy, it is possible to use less water and effectively remove the dust and suppress the generation of dust.

Further, in the charged water particle dispersing device A of the present embodiment, the charged water particles W1 generated by the charged water particle generating unit 2 are ejected from the outside of the air flow R toward the air flow R, so that the charged water particle W1 can be surely and efficiently The charged water particles W1 are carried by the air flow R in one direction T.

Further, in the charged water particle dispersing device A of the present embodiment, the water particles W1 generated by the discharge nozzle unit 6 of the charged water particle generating unit 2 can be charged by the electric field formed by the induction electrode unit 7. The charged water particles W1 can be easily and surely generated and ejected.

In the case of the present embodiment, the plurality of charged water particle generating means 2 constitutes the charged water particle dispersing device A, and the water-based electrode portion 8 to which the reference potential is applied is used as a common one. At the time of the electrode (when the plurality of charged water particle generating mechanisms 2 share the water-side electrode portion 8), the specific electric charge of the charged water particles W1 generated by each of the charged water particle generating mechanisms 2 is lowered.

On the other hand, in the present embodiment, each of the charged water particle generating mechanisms 2 is provided with the water-side electrode portion 8. Therefore, the charged water particles W1 having a desired specific charge can be reliably generated, whereby the dust floating in the air can be reliably and efficiently removed, and the generation of dust can be suppressed.

Further, in the charged water particle dispersing device A of the present embodiment, the water W2 pressurized and supplied is split into the water particles W1, and the charged split charging portion S is disposed in the air flow discharge port 3a of the air flow generating mechanism 1. The charged water particle generating mechanism 2 is disposed on the front side in the one direction T. With this, The charged water particles W1 charged by the split charging unit S are not carried by the air flow R, and for example, can be prevented from being electrically adsorbed to the wind tunnel 3 of the air flow generating mechanism 1 or the like. Therefore, the charged water particles W1 generated and discharged by the charged water particle generating mechanism 2 can be reliably carried in the air flow R and transported in the far direction T, and the dust in the air can be removed more reliably and efficiently. To suppress the generation of dust.

Further, by separating the air flow generating means 1 from the charged water particle generating means 2, it is possible to improve the rationality of transportation or storage of the charged water particle dispersing device A. Further, any number of charged water particle generating means 2 can be attached to the air flow generating means 1, and from this point of view, the rationality of the charged water particle dispersing device A can be improved. Further, the mechanism 1 for generating the air flow R can be separated from the mechanism for the purpose of the mechanism 2 for generating the charged water particles W1, whereby the maintenance of the charged water particle dispersing device A can be improved.

Further, since the charged water particle generating means 2 is configured to generate the water particles W1 having a particle diameter of 100 to 300 μm, the charged water particles W1 after the water particles W1 are charged are transported by the air flow R, and There is a case where evaporation or the number of charged water particles W1 generated and discharged by the charged water particle generating mechanism 2 is small. Therefore, water particles W1 having a particle diameter of 100 to 300 μm are generated by the charged water particle generating mechanism 2, and then charged with a particle diameter of 300 μm or less and split into finer particle diameters by Coulomb force. The water particles W1 can remove the dust floating in the air more reliably and effectively, and suppress the generation of dust.

Further, in the charged water particle generating unit 2, the voltage applied when the charged water particle W1 is generated by the induced charging method is in the range of -20 kV to 20 kV. By this, it is possible to prevent corona discharge from occurring.

Here, when the plurality of charged water particle generating mechanisms 2 are arranged to be displaced from a position different from one direction, the induced electrode portion of the charged water particle generating mechanism 2 disposed behind the one direction T (on the upstream side in the flow direction of the air flow R) When the electric field formed by the seven electric fields interferes with the electric field formed by the induced electrode portion 7 of the charged water particle generating mechanism 2 in the front of the one direction T (the downstream side in the flow direction of the air flow T), the charged water particles W1 cannot be appropriately generated. Hey.

On the other hand, in the present embodiment, the plurality of charged water particle generating mechanisms 2 are disposed on the same plane H orthogonal to the one direction T1, in other words, by using the electric field to charge the water particles W1 as charged water. The position of the induced electrode portion 7 of each of the charged water particle generating mechanisms 2 of the particle W1 is disposed at the same position in one direction T, for example, by an electric field formed by the induced electrode portion 7 of the charged water particle generating mechanism 2 adjacent to one of them. The charged charged water particle generating means 2 prevents the charged water particle generating means 2 from being unable to appropriately generate the charged water particles W1.

Moreover, by forming the electrode 7a in an insulating coating, it is possible to prevent the electrode portion 7 from being induced by applying a high voltage to charge the water particles W1, thereby causing an electrical short circuit or discharge.

In this case, as the insulating material 7b which insulates the electrode 7a of the induction electrode portion 7 for charging the water particles W1, a vinyl chloride resin, a polyphenylene sulfide resin, a urethane resin, or a polytetrafluoroethylene is used. The resin, the polychlorotrifluoroethylene resin, the ceramic, and the crucible can generate charged water particles W1 having the same or higher specific charge with respect to the charged water particles W1 generated by the uninsulated electrode 7a.

Further, in the present embodiment, the plurality of charged water particle generating means 2 is configured to apply a charged water particle dispersing device A to the induction electrode portion 7 of the plurality of charged water particle generating means 2 by one power source 33. The current limiting mechanism 36 can be provided in each of the plurality of voltage application wires 32 that connect the induction electrode portion 7 of the plurality of charged water particle generating mechanisms 2 and the power source 33, whereby even if one of the charged water particle generating mechanisms 2 is short-circuited, It is also possible to limit the current flowing in the other charged water particle generating means 2, and to prevent a short circuit from occurring in the other charged water particle generating means 2.

In addition, by using the charged water particle generating means 2 to generate the charged water particles W1 of 1 to 2 L/min, it is possible to secure a certain amount of water supply amount (distributed water amount) of the charged water particles W1, and to stably generate 0.1 mC/ The charged water particles W1 having a high specific charge of kg or more can reliably and effectively remove the dust floating in the air and suppress the generation of dust.

In the above, the embodiment of the charged water particle dispersing device of the present invention has been described. However, the present invention is not limited to the above-described embodiment, and can be appropriately modified without departing from the scope of the invention.

For example, in the present embodiment, the use of the charged water particle dispersing device of the present invention for removing dust generated by tunnel excavation work, demolition work, and the like, and suppressing generation of dust have been described, but it is a matter of course that the charged water particles of the present invention are used. The spreading device is not limited to tunnel excavation or demolition, and can be applied to all cases where it is necessary to remove floating dust in the air and prevent dust from scattering. For example, it can be applied to excavation removal of a contaminated soil, purification work, or removal work including asbestos materials, and prevention of scattering of dust containing harmful substances. Also, substances such as asbestos needles and very high scattering properties (Dust) can be easily adsorbed to the charged water particles W1 by Coulomb force and gradient force, and a particularly remarkable effect can be obtained by being applied to the present invention.

In the present embodiment, the discharge center axis O4 of the charged water particles W1 ejected from the respective charged water particle generating means 2 intersects a point P on the central axis O1 of the air flow R flowing in one direction T, and the plural The charged water particle generating mechanism 2 is disposed outside the air flow R to constitute a charged water particle dispersing device A.

On the other hand, as shown in FIG. 7 and FIG. 8 , the charged water particle generating unit 2 can arrange the discharge central axis O4 of the charged water particles W1 ejected from the charged water particle generating unit 2 in one direction T, and further The air flow generation mechanism 1 is disposed in a plurality of places around the charged water particle generation mechanism 2 to constitute a charged water particle dispersion device B.

In this case, the plurality of airflow generating mechanisms 1 are disposed around the charged water particle generating mechanism 2 in a state in which the discharge center axis O4 is in the one direction T (the circumferential direction in which the charged water particle generating mechanism 2 is substantially centered) The air flow R flowing in one direction T is formed around the charged water particles W1 generated and discharged by the charged water particle generating mechanism 2.

Further, similarly to the present embodiment, the charged water particles W1 generated and discharged by the charged water particle generating means 2 can be transported in one direction T by the air flow R generated by the air flow generating means 1, and the air flow R can be used. The charged water particles W1 are transported to a distant place. Thereby, the flow direction of the air flow R, that is, the one direction T, is directed to the desired direction, so that the dust floating in the air in the desired direction can be electrically captured and removed by the charged water particles W1, and the air flow R is used. The charged water particles W1 are transferred to the far side, and the large range of floating powder can be used. Dust removed.

Further, when the one direction T is directed toward the dust generation target of the dust generation source or the like, and the charged water particles W1 are transported by the air flow R, the charged water particles W1 can be blown to the distant dust generation suppression target, and the object can be suppressed. The dust generation suppressing object is wetted by the charged water particles W1. Therefore, if the air flow R is directed toward the dust generation target such as the dust generation source, the charged water particles W1 can be used to wet the dust generation source to which the dust generation is suppressed, and the dust (particles) can be captured, and the dust can be suppressed. The suppression object is scattered and dust is generated.

As described above, in the charged water particle dispersing device A of the present embodiment, even when the relative position or the number of the charged water particle generating means 2 and the air flow generating means 1 is changed to constitute the charged water particle dispersing device B, The other configuration is the same as that of the present embodiment, and the effects of the configuration can be obtained in the same manner as in the present embodiment.

When the air flow generating means 1 is disposed in the vicinity of the charged water particle generating means 2 to form the charged water particle dispersing device B, the plurality of charged water particle generating means 2 may be disposed in the vicinity of the center, and the plurality of air flow generating means 1 may be disposed. It is disposed around these charged water particle generating mechanisms 2. Further, the number of the air flow generating means 1 may be two. In this case, the charged air particle generating means 2 is preferably disposed in the middle, and the two air flow generating means 1 are symmetrically arranged.

Further, as long as the charged water particle generating means 2 can generate and discharge the charged water particles W1, the air flow generating means 1 can generate the air flow R flowing in the one direction T, and the charged water particle generating means 2 and the air flow generating means 1 do not have to It is limited to being constructed as in the present embodiment.
