Description

  The present invention relates to a method and apparatus for extinguishing fog used for extinguishing fog that flows into facilities such as roads, routes, airfields, bridges, and golf courses.

  Examples of conventional defoaming methods include those described in Patent Documents 1 to 4.

  Patent Document 1 is a method of sucking a mist, heating and drying it, and then refluxing it to the atmosphere. Patent Document 2 is a method of inducing corona discharge to form a mist and capturing it, and forming an air curtain to enter the mist. Patent Document 3 is a method of irradiating fog or a net that reflects this with a far infrared ray of a specific wavelength to split the fog particles, and Patent Document 4 is a halogen lamp having a wavelength of 3 μm as a peak wavelength. This is a method of irradiation and self-division.

  However, the heating-type anti-fogging method that promotes evaporation in Patent Document 1 requires a large-scale heating device and cannot efficiently transmit heat.

  Although the method of inducing corona discharge in Patent Document 2 to capture the mist by forming water droplets or the method of forming an air curtain to prevent the mist from entering, the large discharge device or the compressor device is required. The efficiency of defrosting was low.

  In the method of directly irradiating the mist with far-infrared rays having a specific wavelength in Patent Document 3 and reflecting the same with the net, the fine water droplet particles (particle size: 10 to 30 μm) of the mist are split to a particle size of 7 μm or less by the action of infrared rays. Requires large heat and kinetic energy.

  Moreover, since a wide wavelength of about 3 μm full width at half maximum having a maximum peak in the wavelength range of 6 to 25 μm is irradiated, the full width at half maximum having maximum absorption at 3 μm, 6 μm, and 9 μm of wavelengths that resonate with the molecular vibration of water. Since the irradiation wavelength width is much wider than the absorption wavelength band of 5 μm and energy is supplied to other than the fog, the energy is dissipated to the natural world and the influence on the environment is great.

  The method of Patent Document 4 in which a halogen lamp having a wavelength of 3 μm as a peak wavelength (full width at half maximum of about 3 μm) is irradiated with fog and self-split has the same problem as Patent Document 3.

[Fog eliminating device]
FIG. 1 is a schematic perspective view of an anti-fogging device installed on a road.

  As shown in FIG. 1, the anti-fogging device 1 is provided on both sides of the road 3 that is a facility. The anti-fogging device 1 is disposed in the fog passage, operates when the fog is generated and flows into the road 3, and extinguishes. Note that the generation and flow of fog has a certain pattern depending on the area and facility. This pattern is grasped in advance, and the fog eliminating apparatus 1 is installed in the fog passage.

  The operation / non-operation determination of the anti-fog device 1 is performed using image recognition or a sensor, and the degree of operation is controlled in consideration of the fog concentration, particle size, and distribution.

As shown in FIG. 1 and FIG. 2, the fog eliminator 1 includes an aggregation network assembly 5, a plurality of irradiation lamps 7 as a light irradiation unit, a CO ₂ laser output unit 8, and a far infrared sensor 10 as a fog generation detection unit. It has.

  The aggregation network assembly 5 includes a plurality of aggregation network bodies 9 as a network aggregation medium, and each aggregation network body 9 is formed in a rectangular surface shape, and is disposed, for example, vertically long. Both side edges of each aggregated net 9 are coupled to an insulating support member 11 and can be folded in a folding screen between the columns 13 toward one of the cities 13. The folding network group 5 can be folded and unfolded by movably supporting the support members 11 on the installed rails and driving the wires connecting the support members 11 with an electric motor.

The irradiation lamps 7 are alternately arranged opposite to each other in consideration of the irradiation angle of the infrared light from both sides of the aggregation network 9 in the width direction. For example, in FIG. 2, two irradiation lamps 7 are arranged on both sides of each aggregated net 9, and the positions of the opposed irradiation lamps 7 are shifted along the support material 11, so that the entire aggregated net 9 is arranged. It is considered that infrared light is irradiated.

  The irradiation lamp 7 as a light irradiation unit is a combination of an infrared lamp 17 such as carbon or a metal heater and a bandpass filter 19 and includes a reflector 21 that obtains an irradiation angle θ.

  In consideration of the irradiation angle θ, when the outer edges of the irradiation range are alternately arranged as shown in FIG. 7, infrared light can be irradiated to almost the entire surface of the aggregation network 9 without waste.

The irradiation lamp 7 can be a light emitting diode (LED) or a laser oscillator.
[Extinction]
In the embodiment of the present invention, irradiation with infrared light from the irradiation lamp 7 causes water molecular vibrations to resonate and agglomerate, and agglomeration is promoted by forming a standing wave sound field in the aggregation network assembly 5 to promote aggregation. The assembly 5 is eliminated as a nucleus of aggregation.

(Molecular vibration)
The irradiation lamp 7 is energized and absorbed by water at a maximum wavelength of 1.5 μm, the half-value width is 0.3 μm, the maximum wavelength is 2 μm, the half-value width is 0.5 μm, the maximum wavelength is 3 μm, the half-value width is 0.7 μm, the maximum wavelength is 4.5 μm, and the half-value width is 1.5 μm. It outputs infrared light with a half-width of 1.5 μm at a wavelength of 6 μm and a half-width of 2 μm at a maximum wavelength of 10 μm.

  This output is intermittently performed like a high speed alternating current or pulse.

  FIG. 8 is a graph showing the absorption wavelength of water.

  As shown in FIG. 8, when the absorption wavelength 3 μm of the lowermost water is targeted and the emission spectrum 23 of the infrared lamp 17 is passed through the bandpass filter 19, the red emission spectrum 25 having a maximum wavelength of 3 μm and a half width of 0.7 μm is obtained. Outputs external light.

The CO ₂ laser output unit 8 outputs infrared light having an emission spectrum 30 of 10 μm, targeting an absorption wavelength of 10 μm at the lowest water.

  In the case of an LED, the emission spectrum 27 is used as it is, and in the case of a laser, the emission spectrum 29 is obtained.

  In this way, infrared light having a wavelength that is absorbed by water is intermittently applied to the mist to resonate and absorb the molecular vibrations of the water, thereby agglomerating and erasing the bonds.

(Standing wave sound field)
Furthermore, in this embodiment, the agglomerated net body 9 and the supporting material 11 and the support column 13 supporting the same are irradiated with infrared light, and the intermittent frequency of the infrared light is resonated as the frequency at which the sound field of the sound wave where the mist is agglomerated is fixed. To form a standing wave field and promote aggregation.

  By the intermittent irradiation of the infrared light by the irradiation lamp 7, each of the aggregated nets 9 or the aggregated grids 9 </ b> B absorbs the infrared light intermittently and resonates with the natural frequency to form the aggregated network set 5. A standing wave sound field is formed.

  That is, the sonic sound field in which the mist is aggregated is resonated as a frequency to be fixed, and the mist is aggregated and combined to be erased.

  In the standing wave sound field, Joule heating is performed by high-speed alternating current conduction or pulse conduction on one side 9Ba in the thickness direction of the wire 15 of each aggregated net 9, the core 15Aa of the wire 15A, and the aggregated lattice film body 9B. It can also be formed by generating sound waves during expansion.

  When the wire 15 of each aggregated net 9 or the core 15Aa of the wire 15A and the one side 9Ba in the thickness direction of the aggregated lattice film 9B are formed of a piezoelectric effect material, the fog is aggregated by applying a voltage with a high-speed intermittent frequency. A standing wave sound field can be formed by resonating the sound wave sound field to be resonated as a standing frequency. Examples of the piezoelectric effect material include a piezoelectric ceramic.

A standing wave sound field is formed by intermittently absorbing infrared light, joule heating is performed by alternating current or pulse current, and is formed by generating sound waves during thermal expansion. The case where it is formed by application is applied independently, or the case where it is formed by absorbing infrared light intermittently as in the example and Joule heating is performed by AC energization or pulse energization, and by the generation of sound waves during thermal expansion Any case of forming by any combination such as combining with the case of forming is possible.

  Therefore, in this example, the aggregation medium is the aggregation network 9 formed of a conductive material, and the monitoring control unit 31 configures an energization control unit that energizes the aggregation medium at an intermittent frequency.

  When the agglomerated medium is the agglomerated lattice film body 9B formed of a piezoelectric effect material and forms a standing wave sound field by resonating by applying a voltage at an intermittent frequency, the monitoring control unit 31 causes the piezoelectric material of the intermittent frequency to be generated on the agglomerated medium. A piezoelectric control unit that performs application is configured.

The far-infrared sensor 10 detects the generation of fog and inputs it to the monitoring control unit 31, which is the cause for the monitoring control unit 31 to operate and stop each unit. Accordingly, the far-infrared sensor 10 constitutes a fog generation detection unit.

  In step S9, a determination process of “visibility is below a certain value?” Is executed, and when it is determined by the detection signal of the far infrared sensor 10 that the visibility is below a certain value (Yes), the process proceeds to step S10. When it is determined that the visibility exceeds a certain value (No), the process proceeds to step S11.

In step S10, the process of “CO ₂ laser irradiation” is executed, and the CO ₂ laser output unit 8 is controlled by the monitoring control unit 31 to output the CO ₂ laser, thereby expanding the fog extinguishing capability.

  From step S10, the process returns to step S6, and S9 and S10 are repeated until it is determined in step S7 that the fog has disappeared. If the visibility exceeds a certain value, the process proceeds to S11.

In step 11, a “CO ₂ laser stop” process is executed, and the CO ₂ laser output unit 8 is controlled by the control of the monitoring control unit 31 to stop the CO ₂ laser output and maintain the current fogging capability.

  An agglomerated network body 9 or an agglomerated lattice film body 9B, which is formed of a piezoelectric effect material such as piezoelectric ceramic and resonates by applying a voltage at an intermittent frequency to form a standing wave sound field, is installed in a fog passage.
