Description

INDUSTRIAL APPLICABILITY According to the present invention, it is possible to reliably remove volcanic ash, including suspended particulate matter such as volcanic ash, dust, dust and pollen from the outside air, and the durability is improved so that it can be used for a longer period of time. It is related to the volcanic ash filter device.

Conventionally, so-called large-sized air conditioners installed in office buildings and condominiums, as well as air conditioners used in ordinary households, have a normal general structure, that is, an air filter device using a resin filter. Is used. Then, the filter device in the air-conditioning equipment captures dust, dirt, pollen, etc. in the outside air in the resin filter, and the safe and comfortable operation of the air-conditioning equipment is planned.

By the way, Japan is also one of the leading volcanic countries, and so-called active volcanoes are everywhere. There are still areas where active volcanoes are erupting, and the treatment of falling volcanic ash has become an urgent issue in these areas.

Therefore, the use of air-conditioning equipment is indispensable even in such an eruptive activity area, and when using the air-conditioning equipment in the eruptive activity area, it is indispensable to use a filter device that can reliably and smoothly remove volcanic ash. Has been done.

Volcanic ash is very annoying and can get anywhere in your home or workplace. For example, it can get inside expensive equipment such as televisions, computers, and cameras, causing irreparable failures.

Moreover, unlike ordinary household dust and dirt, volcanic ash has a sharp crystalline structure, so when wiping or wiping it off, it may scratch the surface of furniture and electrical appliances and scratch it. ..

Also, as the air dries, volcanic ash is easily rolled up, diffused and moved by the wind and the passage of automobiles.

As a result, the amount of floating volcanic ash is so high that it can reach levels that adversely affect human health.

Volcanic ash moves under the influence of rain and wind, while being fixed to the soil by plants such as grass. However, for large-scale ash fall activities, the process is very slow and requires manual cleaning of volcanic ash to remove it from the residential area.

In addition, the wind can re-enter the already cleaned area, which can remain floating around you for months or even years after the eruption.

Volcanic ash has a great influence on air-conditioning equipment in particular, and it is necessary to frequently replace resin filters used in air-conditioning equipment for several months after the ash falls. For example, careful attention should be paid to the filters of air conditioners and heating equipment.

As a filter device used in a conventional office building or condominium, a pre-filter made of a non-woven fabric or synthetic fiber having a predetermined thickness is usually used.

However, in the case of a filter device composed of a pre-filter made of a non-woven fabric or synthetic fiber having a predetermined thickness, volcanic ash or the like immediately accumulates in the filter such as a non-woven fabric or synthetic fiber having a predetermined thickness. This caused the filter to become clogged and the filter effect suddenly disappeared, so it had to be replaced in a short period of time.

The volcanic ash filter device according to the present invention uses a material for a filter member that repels and drops the colliding volcanic ash due to the repulsive force of the filter member without adhering the volcanic ash, and also creates a shape of the filter member. It does not clog the filter member, does not require short-term replacement, does not need to be washed frequently for reuse, and is optimal for areas with different ash concentrations and ash particle sizes. It has the excellent effect of being able to provide a selectable volcanic ash filter device.

Hereinafter, the volcanic ash filter device 1 according to the present invention will be described with reference to the drawings.

The volcanic ash filter device 1 first has a frame body 3 having a substantially rectangular shape. Then, the frame body 3 penetrates the front and back surfaces of the frame body 3 formed by framing a pair of horizontal frame members 2a and a pair of vertical frame members 2b having a predetermined width and a predetermined length in a substantially rectangular shape. It is formed to have an opening 4 to be formed.

The materials of the horizontal frame member 2a and the vertical frame member 2b are not limited in any way. It may be made of a metal member such as an aluminum material that is light in weight and does not rust, or a recycled chip material such as PET (polyethylene terephthalate), which is a member corresponding to recycling, may be used. ..

Then, in the opening 4 of the frame body 3, the filter member holding member 5 is first attached over the entire surface of the opening 4 so as to close the opening 4.

Here, the filter member holding member 5 is formed so that the wave shape is U-shaped, and the U-shaped waves in the horizontal direction are continuous in a zigzag U-shape and an inverted U-shape. There is.

Regarding the filter member mounted in the opening 4, in recent years, for example, in order to extend the replacement time and service life of the filter member, instead of mounting a flat filter member in a plane, for example, a resin filter member is used. Is generally bent into a V shape and an inverted V shape to be continuous in a zigzag manner, and a filter member processed to expand the filter area is attached.

However, in the present invention, the filter member is formed in a U-shape and an inverted U-shape instead of being bent in a V-shape and an inverted V-shape. The reason will be described later.

Further, in order to maintain the shape of the filter member 6 for a long period of time instead of attaching only the filter member 6, a configuration is adopted in which the filter member holding member 5 is also provided on the back surface of the filter member 6.

Here, the filter member holding member 5 is configured as a metal mesh member, and a large number of openings 8 (see FIG. 7) are formed over the entire surface thereof.

When a gas such as air containing volcanic ash or the like passes through the opening 8, the volcanic ash does not pass through the filter member 6 attached to the filter member holding member 5, and only the gas such as air passes smoothly. It is configured so that it can be done.

As the filter member holding member 5, a so-called SUS mesh material is mainly used among the metal members.

In this SUS mesh material, one wave shape is formed in a U shape, and the waves forming the U shape in the horizontal direction are in a continuous wave shape in which the U shape is zigzag and the inverted U shape is continuous. Further, it is composed of a SUS mesh material having a strength capable of maintaining its continuous corrugated shape, for example, a SUS304 mesh. As the SUS304 mesh, for example, a φ0.4 × 12 mesh is used.

The filter member holding member 5 is by no means limited to the SUS304 mesh, but may be a SUS mesh material having strength capable of holding the U-shaped and inverted U-shaped and zigzag continuous continuous wave shapes. Required.

Further, the number and size of the plurality of large number of openings 8 are not limited in any way, but as a result of forming the plurality of openings 8 in a large number, the U-shape and the inverted U-shape are continuous. The shape to be used must not be maintained. To the last, it is necessary to select the number and size of the openings 8 so as to have the strength to maintain the U-shape and the shape continuous with the inverted U-shape.

Next, the filter member 6 is made of SUS316 mesh or the like. That is, it is generally composed of a SUS mesh material that can flexibly change its shape, for example, SUS316 or SUS316L.

In particular, SUS316 has φ0.05 × 200 mesh (opening 77 μm), φ0.06 × 150 mesh (opening 109 μm), φ0.1 × 100 mesh (opening 154 μm), φ0.1 × 80 mesh (opening 220 μm). ) Is an example.

FIG. 7 is an enlarged description of the mesh portion of the filter member 6 or the filter member holding member 5, and shows standards for the number of meshes, mesh pitch, opening ratio, and aperture ratio. Reference numeral 9 indicates an opening.

The SUS mesh material used for the filter member 6 has an extremely small opening 9 and is configured to be permeable to volcanic ash.

Further, since the filter member 6 is flexible, by installing it in contact with the filter member holding member 5, it can be easily formed into a continuous wave shape which is continuous in a U shape and an inverted U shape and a zigzag wave shape. It can be formed and its shape can be held for a long time by the filter member holding member 5.

As described above, both the filter member 6 and the filter member holding member 5 are made of SUS mesh material in the present invention.

The SUS mesh material is known as a metal having high resilience, and a substance that collides with the SUS mesh material, for example, volcanic ash, is repelled by the repulsive force of the SUS mesh material without adhering to the SUS mesh material, and the SUS mesh material is used. It will separate from the surface of the material and fall. Therefore, the filter member 6 does not become clogged.

The usage state of the volcanic ash filter device 1 according to the present invention will be described above.

Normally, the volcanic ash filter device 1 is installed on the upstream side of the air filter. Then, the installation surface of the filter member 6 is attached to the air inflow side so as to face the inflowing air. Then, a filter member holding member 5 is arranged on the back side of the filter member 6 to hold the filter member 6 and maintain the continuous corrugated shape of the filter member 6.

Here, the air containing volcanic ash tries to pass through the filter member 6 of the present invention. At this time, since the volcanic ash has a size that cannot pass through the opening 8 of the filter member 6, it collides with the filter member 6. As shown in FIG. 6, in particular, the bottom 7 of the U-shaped wave is hit by volcanic ash from the front at a substantially right angle to the surface of the bottom 7. Then, since the filter member 6 is a SUS member and has a large repulsive force made of metal, the volcanic ash is repelled without adhering to the filter member 6 and falls down. The volcanic ash that collided with the top of the U-shaped wave is also bounced off and falls.

As shown in FIG. 6, volcanic ash may adhere to both side surfaces of the U-shaped wave, but as described above, volcanic ash does not adhere to the bottom 7 of the U-shaped wave. No clogging of the filter member occurs.

Here, as shown in FIG. 5, the present inventors are also conducting an experiment in which the filter members 6 are arranged in a V shape to see if volcanic ash adheres. In this case, as shown in FIG. 5, a large amount of volcanic ash adhered to the V-shaped bottom, and as a result, the filter member 6 was clogged.

In addition to the U-shaped and inverted U-shaped continuous shapes, it is also conceivable to process the shapes of the filter member 6 and the filter member holding member 5 so as to collide with the volcanic ash from the front. For example, it is conceivable to make the shapes of the filter member 6 and the filter member holding member 5 continuous in a concave shape and a reverse concave shape.

In this case as well, the volcanic ash is repelled and falls on the surface where the volcanic ash collides from the front, that is, the bottom surface of the recess.

By the way, in the present invention, a plurality of types of filter members 6 made of SUS mesh material having different openings 9 are prepared. Japan is one of the leading volcanic countries and has many active volcanoes. However, the concentration of volcanic ash in the air and the size of volcanic ash are not exactly the same in each area where the volcano is held. In some areas, the concentration of volcanic ash is high, and in other areas, the particle size of volcanic ash is relatively large. Therefore, it is important to select the optimum filter member 6 for each area, that is, the filter member 6 having the optimum opening 9.

Therefore, in the area where the volcanic ash filter device 1 is planned to be used, the volcanic ash concentration (mg / m ³ ) or the particle size of the volcanic ash in the area is investigated and confirmed in advance, and the results of these investigations are followed. It is important to select and use filter members 6 with different openings 9.
