1 is a flowchart of a fugitive dust removal method according to an embodiment of the present invention.

Referring to FIG. 1, the method for removing scattered dust according to an embodiment of the present invention may include a step of providing an injector connected to a water pipe and an air pipe. Water is supplied through the water pipe, and compressed air can be supplied to the injector through the air pipe. Accordingly, water and compressed air in the injector can be mixed and sprayed with water vapor.

First, water is supplied to the sprayer through a water pipe, and compressed air is supplied through the air pipe. Thereafter, the injector mixes the water and the compressed air, and can inject it to the outside. In the injector, the mixed water and compressed air can be turned into water vapor as they are injected outside. For example, a jetting port is formed in the jetting device, and the jetting port may be formed in a nozzle shape. A mixture of compressed air and water can be discharged from the jetting nozzle very quickly to the outside. Since the amount of compressed air discharged is larger than that of water, the mixture is discharged as water vapor, and the water vapor can be discharged further by the spraying force of compressed air. As the pressure increases as the pressure increases, the steam can be discharged more quickly through a larger pressure drop.

The water vapor injected to the outside can be transferred to a desired region by a blower installed adjacent to the injector. For example, water vapor can be transported to areas where dust or fog dust is generated at a construction site. That is, the water vapor can be transferred through the first blower to excavation work, trench construction work, or demolition work where many scattered dusts are generated, so that scattered dust can be adsorbed on water vapor. The water vapor adsorbed by the scattered dust is collected and treated. Specifically, a water vapor dome is formed on an excavator or an upper part of the construction site, thereby preventing scattered dust from being scattered to the outside of the construction site. Accordingly, it is possible to prevent fugitive dust more easily by preventing the human being from sprinkling water in the vicinity of the excavator, thereby preventing human accidents, and adsorbing the dust scattered on the excavator to water vapor. Particularly, by collecting the water vapor absorbed by the scattered dust, the water vapor is converted into the water again, and it is flowed to the surrounding sewage etc., so that the scattered dust in the construction site can be treated more easily.

The water supplied to the injector may further include a heating step and a compression step. When the water is heated and sprayed with water vapor, a more enhanced ascending air stream can be formed. In particular, the heated water can be pressurized again to suppress the water vapor that may be generated upon heating, thereby supplying heated water to the sprayer. This makes it possible to reliably supply warm water to the sprayer in the water pipe.

And an ascending step of supplying air to the steam transferred by the first blower to lift the air from the ground. For example, a second blower installed apart from the first blower and capable of directing water vapor and capable of supplying air can be provided. By means of the second blower the water vapor can carry water vapor above the area intended to form the water vapor dome. That is, the steam discharged from the injector is conveyed by the first blower, and the upward airflow is generated by the second blower to form the steam dome. Further, since the water is heated in the water pipe and supplied to the injector to be discharged, the temperature of the water vapor can be made higher than the ambient temperature, so that the upward flow can be formed more easily.

The water vapor adsorbed by the scattered dust can be sucked through the collecting part spaced from the ground. The collecting part can suck the surrounding air. Particularly, the water vapor adsorbed by the scattered dust is moved to the ground by gravity, and can be sucked into the trapping portion due to the negative pressure formed in the trapping portion during the movement. In the collecting part, a lot of water vapor collects again and the water phase changes, and the scattering dust can be discharged to the outside through the discharge pipe connected to the collecting part.

A magnetic field can be formed around the collecting portion. For example, the magnetic force portion can be provided around the collecting portion. The coils may be located within the magnetic portion, and may include supplying current to the coils and forming a magnetic force around the coils. Thereafter, it may include the step of inducing water vapor through the magnetic force to float the water suspended in the air. That is, the scattered dust is electrically zero, but the water vapor becomes conductive, so that the water vapor can be induced in the direction in which the magnetic force is generated by the magnetic force. The coil may be formed around the collecting part, and the water vapor, which is not sucked into some collecting part, may be brought into contact with the dust net and reduced to water by installing a dust net around the collecting part. Through this process, the steam dome is formed, and then the water vapor is inhaled and the dust is contacted with the dust, and then the water is reduced to water, thereby removing scattered dust generated in the construction site.

2 is a schematic diagram of a fugitive dust removal system in accordance with an embodiment of the present invention.

2, the fugitive dust removal system 100 may include an injector 10, a first blower 21, and a second blower 22.

A plurality of the injectors 10 are formed, and each of the injectors 10 is connected to the water pipe 111 and the air pipe 121. The injector (10) and the first blower (21) may be connected to the moving means (130). For example, the injector 10 and the first blower 21 are installed in a vehicle luggage compartment and can set the injection area through movement of the vehicle.

Water is supplied to the injector 10 through the water pipe 111 and compressed air can be supplied to the injector 10 through the air pipe 121. Water and compressed air are mixed in the injector 10, and steam can be discharged to the injection port 133 formed in the injector 10. Water vapor can float in the air and adsorb it with fine dust. This can eliminate fugitive dust from the construction site.

The first blower 21 may be installed adjacent to the injector 10. The first blower 21 can rapidly transfer the water vapor to the required area while radiating the water vapor injected from the injector 10 into the air. The injector 10 can be installed around the first blower 21. For example, the injectors 10 may be spaced apart from the first blower 21 at regular intervals. In particular, the discharge direction of the injector 10 may be inclined toward the first blower 21. For example, the water vapor discharged from the injector 10 is a mixture of compressed air and water, passes through the injection port 133 of the injector 10, generates a pressure drop, speed energy is increased by a pressure drop, The steam can be supplied through the blower 21 to a region where stable and accurate formation of the steam dome is required. This has the advantage that water vapor dome is formed at the upper part of the work site, water is saved rather than water is sprinkled directly on the work area, watering by manpower is not necessary, and human accidents can be prevented.

The second blower 22 may be installed apart from the first blower 21. The second blower 22 is installed lower than the first blower 21 and can supply air so as to form an upward flow in the steam. For example, air can be supplied to the water vapor fed through the first blower 21 in a direction perpendicular to the paper surface. The water vapor can be injected into the air with a change in velocity energy due to the pressure of the compressed air and the pressure drop, and can be transported at a very high speed. Through the air supplied from the second blower 22, the water vapor being conveyed can be moved in the vertical direction. As a result, the water vapor moves to the upper part of the building site, the slowed water vapor floats in the air, and a steam dome can be formed on the upper part of the construction site.

 The collecting section 30 may be installed apart from the ground. For example, the collecting section 30 can be installed at the upper end of the post 32 installed on the ground. As another example, the collecting part 30 may be installed at the upper end of the vertical column of the fence 110 installed around the building site.

A plurality of collecting units 30 are installed along the construction site fences 110, and each collecting unit 30 can be connected to the discharge pipe 33. The collecting section 30 can suck air. For example, water vapor is transferred to a region where scattering dust is generated to form a steam dome. At this time, the scattered dust is adsorbed by the water vapor and is floating in the air. At this time, the collecting section 30 can suck up the water vapor before the water vapor adsorbed by the scattering dust falls on the ground. The large amount of water vapor collected by the collecting section 30 can be reduced to water. More specifically, the collecting section 30 can be operated according to the set construction area.

For example, in the construction site, it is common that construction is carried out by setting a certain area in consideration of the movement route of the equipment and the movement of materials and people. Therefore, it is possible to operate scattering unit 30 adjacent to the construction site to manage scattering dust. Specifically, when civil engineering work is performed through an excavator, a steam dome is formed on the excavator, adsorbed on the steam by the scattered dust generated by the excavator, and then the collecting part (30) It can float in the air of the zone and concentrate the scattered dust and the water vapor adsorbed. At this time, the operation of the collecting part 30 is stopped by the distance from the work area, so that the energy saving is possible and the suction pressure of the operated collecting part 30 is made stronger so that the scattered dust collected through the steam dome It can be more completely inhaled.

The collecting section 30 can be connected to the discharge pipe. The discharge pipe may be connected to a suction motor. For example, the discharge pipe can be connected to each collecting part, and the water vapor adsorbed by the scattering dust introduced into the collecting part can be collected into the discharge pipe and discharged to the water. The water vapor attracted toward the collecting unit 30 may collide with the dust net 120 of the fence 110 and may flow into the ground along the fence 110 with water droplets. Through the water vapor induction of the collecting section 30, the scattering dust can be discharged to the water.

3 is a perspective view according to another embodiment of the collecting part.

Referring to FIG. 3, the attracting portion 34 may be formed around the collecting portion 30. An inclined surface is formed inside the collecting portion, and the inclined surface is inclined toward the inner suction port connected to the discharge pipe (33) from the outside of the collecting portion. Air can be introduced into the discharge pipe (33) through the suction port. Accordingly, the air can be sucked into the discharge pipe 33 more quickly by the shape of the collecting part 30, and the attracting part 34 is formed around the collecting part 30, So that the water vapor suspended in the air can be attracted toward the collecting part 30. For example, the attracting section 34 may include a power supply section 34a and a coil section 34b. The coil portion 34b is connected to the power source portion 34a and a magnetic force can be formed around the collecting portion 30 by the movement of current according to the power supply. Accordingly, the water vapor suspended in air and adsorbed by the scattered dust can be directed toward the trapping portion 30, and the scattered dust can be removed by collecting the steam more efficiently.

FIG. 4 is a conceptual diagram of the injector shown in FIG. 1, FIG. 5 is a cross-sectional view of a compression pipe at a portion to which the connector shown in FIG. 4 is connected, and FIG. 6 is a view illustrating movement of the third chamber shown in FIG.

4 to 6, the injector 10 may include a first chamber 11, a second chamber 12, and a third chamber 13. The first chamber 11 is connected to the water pipe 111, and water supplied from the water pipe 111 can be received. The second chamber 12 is connected to the air pipe 121, and compressed air supplied from the air pipe 121 can be received.

The first chamber 11 and the second chamber 12 are respectively connected to the third chamber 13 and supply the water and the compressed air to the third chamber 13. A check valve 112 may be provided between the first chamber 11 and the third chamber 13. Thus, the water supplied from the first chamber 11 by the compressed air can be prevented from flowing backward.

A regulating valve 122 may be provided between the second chamber 12 and the third chamber 13. The flow rate of the compressed air can be adjusted through the regulating valve 122. Through this, the particle size of water vapor droplets can be controlled. For example, when the inflow amount of the compressed air is increased, the droplet size of the water vapor can be made smaller. In this case, the water vapor can float more stably in the air.

The third chamber 13 may be formed of a first part 131 and a second part 132. The first part 131 may be connected to the first chamber 11 and the second part 132 may be connected to the second chamber 12. That is, water may flow into the first chamber 11, and compressed air may flow into the second part 132. The second part 132 is connected to the first part 131 and can be moved in the first part 131. For example, in the first part 131, a plate surface 131b may be formed between the second parts 132. A plurality of flow paths are formed on the plate surface, and the compressed air introduced into the second part 132 may be introduced into the first part 131 and mixed. A tail portion 132b may be formed at the end of the second part 132. [ When the second part 132 is moved by the connector 19, the tee part 132b closes the flow path formed on the plate surface 131b of the first part 131. [

The inclined surfaces 131a and 132a are formed at the ends of the first part 131 and the second part 132 and the injection port 133 is formed by the combination of the first part 131 and the second part 132 . For example, while the second part 132 is being moved from the first part 131, the inclined surface 132a of the second part 132 may protrude from the inclined surface 131a of the first part 131. Accordingly, the ejected water vapor is changed in spray angle by the changed contact length due to the drawn second part 132. Specifically, if the contact length is long, the frictional force is improved, so that the water vapor can be bent toward the second part 132. Accordingly, it is possible to change the spray angle of the steam discharged through the change in the protrusion length of the second part 132.

A rotation part 17 may be formed between the control valve 122 and the third chamber 13. The rotary part 17 may be formed in a rectangular shape and a connector 19 connecting the second part 132 and the rotary part 17 is connected to one side of the rotary part 17, And the third chamber 13, as shown in FIG. 5A.

The resistance portion 16 is inclined according to the inflow amount of the compressed air, so that the rotation portion 17 connected to the resistance portion 16 can be inclined. The inclination of the second part 132 connected to the connector 19 is adjusted according to the rotation of the rotary part 17 so that the spray angle of the discharged steam can be adjusted. For example, as the inflow amount of the compressed air is larger, the resistance portion 16 can be inclined in parallel with the longitudinal direction of the connection pipe 123. That is, the resistance portion 16 can be positioned horizontally. The rotary part 17 connected to the resistance part 16 is positioned horizontally and the second part 132 can be protruded from the first part 131 through the connector 19. [

The other end of the resistance portion 16 may be connected via a spring and a stationary device 18 may be connected. For example, when the supply of compressed air is controlled by the control valve 122, the resistance portion 16 can be angularly adjusted in a direction perpendicular to the longitudinal direction of the connection pipe 123. In this case, the rotary part 17 is positioned in a direction perpendicular to the longitudinal direction of the connection pipe 123 in accordance with the rotation of the resistance part 16, and is connected to the end of the injection port 133 by changing the position of the connector 19 The nozzle can be positioned toward the front direction by rotating the angle adjusting unit (not shown). That is, the spraying angle of the water vapor discharged in accordance with the rotation of the resistance portion 16 can be adjusted. Specifically, when a large amount of compressed air is introduced, the particle size of the water vapor droplet is very small and can float more smoothly in the air. Accordingly, the discharged steam can be vertically positioned from the injector 10 to radiate water vapor into the air, and a steam dome can be formed by the first blower 21 and the second blower 22 to remove scattered dust. For example, if civil works are being carried out extensively in a construction site, a steam dome must be formed throughout the construction site. In this case, the particles of water droplets are made smaller and an ascending air flow is formed to form a steam dome. Accordingly, the amount of compressed air is maximized, the second part 132 is protruded to increase the frictional force, So that water vapor is radiated into the air.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
