Therefore, for example, Patent Literature 1 discloses an air purification device aimed at preventing such microorganisms from entering and propagating into the device.

  In Patent Document 1, a hydrophilic cloth and a stainless steel wire mesh are integrated by sewing and a corrugated filler is provided in a cleaning part of an air purification device. The structure which improved the contact efficiency with contaminated air is disclosed.

JP 2004-305919 A

However, the filler provided in the conventional air purification apparatus has the following problems.
That is, in patent document 1, since the filler manufactured from a stainless steel mesh and cloth is sewing, there existed a problem that the operation | work took time.
In addition, the stainless steel wire mesh member is expensive, and since it is made of stainless steel, the weight of the filler itself is large, and it is necessary to firmly manufacture a container for holding the filler, which increases the cost. there were.

  The present invention has been made in view of the above-described problems, and includes a filler, a filler manufacturing apparatus, and a filler manufacturing method that can be manufactured by a simple and labor-saving operation and that can reduce costs. The purpose is to provide.

  In order to achieve the above object, in the filler according to the present invention, the filler is disposed in a state of being laminated on the cleaning unit of the air purification device, and is in a state of being overlaid on the surface of the fabric having hydrophilic properties. It is characterized in that it is formed of a plastic mesh that is integrally fused with the cloth, and the cloth and the plastic mesh are bent and formed into a corrugated shape.

  Further, in the filler manufacturing apparatus according to the present invention, the filler manufacturing apparatus is arranged in a state of being laminated on the cleaning unit of the air purification apparatus, and includes a hydrophilic cloth and a plastic mesh, and is provided on the peripheral surface. Waveforms are formed along the circumferential direction, each of which is provided so as to be rotatable about the central axis, and a pair of wave rolls meshing each other's waveforms and a pair of wave rolls. It is characterized in that the crimping portion to be engaged is provided with a feeding portion that feeds the fabric and the plastic mesh in a superimposed state, and a heater for heating the pair of wave rolls.

  Further, in the method for producing a filler according to the present invention, the filler is disposed in a state of being laminated on the cleaning unit of the air purification device, and is a method for producing a filler comprising a hydrophilic fabric and a plastic mesh, the fabric and It is characterized by having a fusion process in which the plastic meshes are integrated by fusing in an overlaid state, and a bending process step in which the fused fabric and the plastic mesh are bent into a corrugated shape.

  In the present invention, a filler unit having a large specific surface area can be formed by stacking the surfaces of fillers on which corrugations are formed. By providing this filler unit in the cleaning unit of the air purification device, water or chemical liquid sprayed in the cleaning unit adheres to form a water film on the surface, and the contaminated air passing through the filler in this water film is efficient. Since the gas-liquid contact often occurs, the pollutant in the polluted air can be transferred into the water film and removed. And since the filling material uses the plastic mesh for the cloth, the plastic mesh can be heated and integrated with the cloth by fusion, and can be easily manufactured as compared with the filling material by sewing. it can.

  Moreover, in the filler manufacturing apparatus which concerns on this invention, it is preferable to provide the 1st cooling part which cools the plastic mesh fuse | melted to the fabric in the downstream position of the crimping | compression-bonding part of the delivery direction of a fabric and a plastic mesh.

  In this case, since the heated plastic mesh immediately after being fused to the fabric is cooled and begins to harden, it can be prevented from further melting, so that it is possible to prevent the problem that the plastic mesh adheres to the corrugated roll. .

  Moreover, in the filler manufacturing apparatus which concerns on this invention, you may provide the 2nd cooling part which cools the wave roll on the side which contact | connects a plastic mesh.

  In this case, the corrugated roll on the side in contact with the plastic mesh is cooled and lower than the heating temperature of the corrugated roll on the side in contact with the cloth, so that the heated plastic mesh immediately after fusing to the fabric becomes the corrugated roll. Problems such as adhesion can be prevented.

  Moreover, in the filler manufacturing apparatus which concerns on this invention, the temperature controller which adjusts the temperature of a pair of wave roll may be provided.

  In the present invention, the temperature of the wave roll can be arbitrarily adjusted according to the melting temperature of the plastic mesh material.

  Further, in the filler manufacturing apparatus according to the present invention, the temperature of the wave roll on the side in contact with the fabric is higher than the melting temperature of the plastic mesh and higher than the temperature of the wave roll on the side in contact with the plastic mesh in the crimping part. It is preferable that it is set.

  In the present invention, heat is transmitted from the wave roll on the side in contact with the fabric through the fabric, and the plastic mesh is melted and fused to the fabric. At this time, since the temperature of the corrugated roll on the side in contact with the plastic mesh is lower than the heating temperature of the plastic mesh, the problem that the heated plastic mesh immediately after fusing to the fabric adheres to the corrugated roll is prevented. be able to.

  According to the filler, the filler manufacturing apparatus, and the filler manufacturing method of the present invention, the filler can be formed by fusing the plastic mesh to the fabric by fusion, and filling by conventional sewing is possible. It can be manufactured by a simple operation that is less time-consuming than the material. In addition, since the mesh material is plastic, the material cost can be reduced, and for example, it is lighter than when a stainless steel mesh is used, so a filler unit in which a plurality of fillers are laminated. The support structure can be simplified, and the cost of the support structure can be suppressed.

It is a perspective view of the filler by embodiment of this invention. It is a sectional side view which shows the fusion | melting state of the filler shown in FIG. It is the figure which looked at the filler from the cloth side, Comprising: (a) is a figure which shows a vertical corrugated filler, (b) is a figure which shows a diagonal corrugated filler. It is a perspective view which shows the assembly state of the 1st filler unit which accommodates a vertical corrugated filler. It is a perspective view which shows the assembly state of the 2nd filler unit which accommodates a diagonal corrugated filler. It is a figure which shows the structure of the bending apparatus for manufacturing the filler of FIG. It is a figure which shows the structure of the air purification apparatus provided with the filler unit.

  Hereinafter, a filler, a filler manufacturing apparatus, and a filler manufacturing method according to embodiments of the present invention will be described with reference to FIGS. 1 to 7.

  A filler 1 shown in FIG. 1 is used in an air purification device 3 (see FIG. 7) used in a clean room or the like, for example, and water or chemicals and contamination are caused by the filler 1 for removing contaminants in the contaminated air taken in. It is for improving the contact efficiency with air. And the filler 1 is manufactured by the bending apparatus 2 (filler manufacturing apparatus) shown in FIG. 6 mentioned later, and is unitized (filler unit 10 of FIG. 3 mentioned later) in the said air purification apparatus 3 in the unit state. It has been incorporated.

  As shown in FIGS. 1 and 2, the filler 1 is formed into a waveform as shown in FIG. 3 by integrating a hydrophilic fabric 11 and a plastic mesh 12 serving as a support material of the fabric 11 by fusion. Has been. Specifically, the cloth 11 and the plastic mesh 12 are integrated by a method of adhering to the cloth 11 by melting the surface of the plastic mesh 12. 1 and 2 show a state in which the waveform is not formed.

  As a material used for the fabric 11, polyester, vinylon, cotton, polypropylene, or the like that can be easily fused to the plastic mesh 12 by heating can be used. In addition, the selection conditions of the fabric 11 are hydrophilic as described above, and can be selected based on chemical resistance, cost, and the like with respect to an object to be removed and a drug. As for the chemical resistance of the fabric 11, polyester and polypropylene are good for removing acidic substances, polyester and polypropylene are good for oxidizing substances, and polyester, polypropylene for organic substances such as solvents. Vinylon, cotton and polypropylene are preferred.

  As the plastic mesh 12 constituting the support material, a material in which the intersections of the fibers are fused is preferably a material that has a small height difference in cross-sectional view and good adhesion to the fabric 11 and does not fray. For example, polypropylene (PP) or the like is employed. The plastic mesh 12 has strength as a face and needs to be easily folded. For example, the plastic mesh 12 is preferably about 10 mesh and the fiber diameter is preferably about 0.3 to 1 mm.

  Here, the one where the temperature difference between the melting points of the fabric 11 and the plastic mesh 12 is larger is easier to integrate, and the one where the melting point of the plastic mesh 12 is lower is preferable from the viewpoint of ease of manufacture (details will be described later). That is, in general, polyethylene has a lower melting point than polypropylene (PP). However, when fusion is performed by actually placing the fabric 11 on the plastic mesh 12 and heating from above with an iron or the like, polyethylene is obtained. In the case of a mesh, polypropylene is suitable as the plastic mesh 12 because the adhesion to the fabric 11 is poor and integration is difficult even if the mesh surface melts.

  As shown in FIGS. 3A and 3B, the corrugated filler 1 after molding has a substantially rectangular shape in plan view (as viewed from the cloth surface). And as the filler 1, with respect to the vertical corrugated filler 1A (first filler) shown in FIG. 3A in which the waveform is formed in the up-down direction or the left-right direction when viewed from the surface, and the up-down direction (left-right direction) Thus, the oblique corrugated filler 1B (second filler) shown in FIG. 3B in which the corrugation is formed in an oblique direction (an inclination direction of about 45 °) is manufactured.

  As shown in FIG. 4 and FIG. 5, the filler unit 10 is formed in a frame shape by laminating the plurality of fillers 1, 1,... The unit case 13 is accommodated. Here, in the filler unit 10, the short side direction of the filler 1 orthogonal to the direction in which the plurality of fillers 1, 1,. The unit case 13 is a frame-like body having four side surfaces whose upper and lower surfaces are open, and a lid portion 13a that forms one side surface of the unit case 13 is attachable and detachable. The plurality of superimposed fillers 1, 1,... Can be taken in and out.

In this embodiment, the filler unit 10 is formed by filling the first filler unit 10A shown in FIG. 4 filled with the vertical corrugated filler 1A and the oblique corrugated filler 1B. Two types of the second filler unit 10B shown in FIG. 5 can be employed.
In the first filler unit 10A shown in FIG. 4, a flat cloth 1C is interposed between the overlapping vertical corrugated fillers 1A and 1A. That is, by using the flat cloth 1C, the corrugated peaks and ridges of the vertical corrugated filler 1A or the valleys and valleys are not in contact with each other with no gap, and the filler unit formed by the corrugations A large number of gaps (air flow paths) communicating in the thickness direction of 10 are secured, and the specific surface area is increased.
As shown in FIG. 5, the second filler unit 10B is arranged such that the directions of the waveforms of the overlapping oblique waveform fillers 1B and 1B are staggered without arranging the flat cloth 1C. Yes. Also in the second filler unit 10B, since the corrugated peaks and peaks or the valleys and valleys do not contact each other with no gaps, a large number of gaps communicating in the thickness direction are secured, and the specific surface area increases. It has been configured.

The filler unit 10 configured as described above is detachably attached so as to block the air passage in the cleaning unit 31 of the air purification device 3 shown in FIG. It is used for the purpose of improving the contact efficiency with air. The air purifying device 3 may be only the first filler unit 10A, only the second filler unit 10B, or a combination of the first filler unit 10A and the second filler unit 10B.
When the height of the waveform of the filler 1 is 6 mm, the specific surface area is about 720 m ² / m ^{3 in} the case of the first filler unit 10A, and the specific surface area is 500 m ^{2 in} the case of the second filler unit 10B. / M ³ or so.

Next, the bending apparatus 2 for manufacturing the filler 1 will be described with reference to the drawings.
As shown in FIG. 6, the bending device 2 has a circumferential surface formed in a waveform along the circumferential direction, and is provided so as to be rotatable about a central axis with a slight gap in the vertical direction. A pair of wave rolls 21, 22, a feed unit (not shown) that feeds the cloth 11 and the plastic mesh 12 between the wave rolls 21, 22, and a heater provided in each wave roll 21, 22 23, 24, the first cooling nozzle 25 (first cooling unit) for cooling the filler 1 delivered between the pair of wave rolls 21, 22, and the peripheral surface of the upper wave roll 21. And a second cooling nozzle 26 (second cooling section) for the purpose.

  The upper corrugated roll 21 and the lower corrugated roll 22 have different rotation directions, and the corrugated portions 21a and 22a formed in a gear shape on the respective peripheral surfaces by the rotation are the contact portions (hereinafter referred to as a crimping portion). P) and mesh with a gear. The distance between the upper wave roll 21 and the lower wave roll 22 is adjusted so that the filler 1 is appropriately formed according to the thickness of the fabric 11 and the plastic mesh 12. Thereby, a waveform is formed in the state in which the fabric 11 and the plastic mesh 12 fed between the two wave rolls 21 and 22 are overlapped.

  The upper wave roll 21 and the lower wave roll 22 are provided with temperature sensors 27 at appropriate positions. The heaters 23 and 24 are for heating the peripheral surfaces of the wave rolls 21 and 22, and a plurality of the wave rolls 21 and 22 are equally arranged. The heaters 23 and 24 and the temperature sensor 27 are respectively connected to the temperature controller 28, that is, the upper wave roll 21 is adjusted to an arbitrary temperature by the temperature controller 28 according to the melting temperature of the material of the plastic mesh 12. It is possible.

  The 1st cooling nozzle 25 cools with respect to the plastic mesh 12 of the filler 1 immediately after a waveform was formed and sent out from a pair of wave rolls 21 and 22 (downstream side with respect to a roll). The second cooling nozzle 26 cools the peripheral surface 21 a of the upper wave roll 21. These first and second cooling nozzles 25, 26 include slit-shaped air outlets 25 a, 26 a that extend along the axial direction of the first and second wave rolls 21, 22.

Next, the manufacturing method of the filler 1 using the bending apparatus 2 is demonstrated.
As shown in FIG. 6, a filler 1 in which a hydrophilic fabric 11 and a plastic mesh 12 are overlapped includes a fusing step of fusing the fabric 11 and the plastic mesh 12 by fusing, and a fused filler. 1 is manufactured by a bending process for forming a waveform.
That is, in a state where the fabric 11 is overlapped on the plastic mesh 12, the fabric 11 is rotated in the reverse direction and fed to the crimping portion P between the pair of wave rolls 21 and 22 heated to a predetermined temperature by the heaters 23 and 24. Then, the fabric 11 and the plastic mesh 12 are fused together while forming a waveform by meshing the corrugated portions 21a and 22a of the wave rolls 21 and 22, respectively.

  The lower wave roll 22 in contact with the fabric 11 side is set to a temperature higher than the melting point of the plastic mesh 12, and the upper wave roll 21 in contact with the plastic mesh 12 side is set to a temperature lower than the melting point. As a result, the plastic mesh 12 comes into contact with the fabric 11, and the surface of the plastic mesh 12 on the fabric 11 side becomes hot and melts, and at the same time, the plastic mesh 12 is pressed against the fabric 11 and formed into a waveform. Further, immediately after the filler 1 in which the fabric 11 and the plastic mesh 12 are fused and integrated moves to the downstream position of the crimping portion P in the delivery direction, the upper surface of the plastic mesh 12 is cooled by the first cooling nozzle 25. The At this time, the plastic mesh 12 that has reached the melting point starts to harden by cooling and is prevented from being melted further. Therefore, the plastic mesh 12 does not adhere to the upper wave roll 21 and is continuously filled. The material 1 can be manufactured.

  In addition, if it manufactures continuously for a long time, the high temperature heat of the lower wave roll 22 will be transmitted to the upper wave roll 21, and the temperature of the upper wave roll 21 will become gradually higher than preset temperature. In order to prevent this, the upper wave roll 21 is cooled from the second cooling nozzle 26, and the temperature of the upper wave roll 21 is adjusted by heating with the temperature controller 28. Thereby, the upper side wave roll 21 can be maintained at a set temperature for a long time, and can be manufactured smoothly.

As shown in FIG. 7, the air purification device 3 takes in the polluted air E1 sucked from a blower fan (not shown) through the duct 31 and removes the pollutant contained in the polluted air E1 using the liquid T. A cleaning unit 4 according to the wet cleaning method is provided. The purified air E2 cleaned by the cleaning unit 4 is exhausted by an exhaust fan 32 provided on the downstream side of the cleaning unit 4.
The cleaning unit 4 is covered with a cylindrical tower-shaped outer shell 41 similar to that generally used, and contaminated air E1 taken from below the outer shell 41 is removed from the outer shell 41. It is made to pass toward the opening 41a at the top end. The opening 41a communicates with the exhaust fan 32 that discharges the purified air E2 purified by the cleaning unit 4 to the clean room.

The cleaning unit 4 is disposed horizontally above the middle part of the outer shell 41 so that the demister 42 closes the flow path. The demister 42, the water spray nozzle 43, and the three-stage filling material unit 10. (101, 102, 103) and the filler support material 44 are disposed in that order downward, and a liquid tank 45 is provided on the bottom 41b of the outer shell 41.
The demister 42 is generally used as a member for removing droplets in a processing gas that accompanies the generation of fine droplets. For example, the demister 42 overlaps a stainless fiber, a glass fiber, or the like in a mesh, or filters a polypropylene fiber or the like. It is formed by processing such as weaving into a shape.

  The watering nozzle 43 sprays the liquid agent T that absorbs the pollutant contained in the contaminated air E1 to the inside of the outer shell 41, and the sprayed liquid agent T is the pollutant contained in the polluted air E1. Depending on the type, water, an alkaline solution, an acidic solution or the like is used. These liquid agents T are mixed with water by a pump 46 connected to a watering nozzle 43, and then supplied to the outer shell body 41 through a flow meter 47.

  The liquid tank 45 absorbs the pollutant contained in the polluted air E1, and uses the liquid agent T that has flowed down along the front and back surfaces of the plurality of fillers 1, 1,. Primary storage. The liquid tank 45 is provided with a drain pipe 45a for draining the stored liquid agent, and the drained stored liquid agent is processed in an organic waste water treatment tank (not shown).

  The filler units 101, 102, and 103 are arranged so as to horizontally block the inside of the outer shell body 41, and are attached to and detached from the outer shell body 41 so that washing and sterilization can be performed when microorganisms propagate. It is attached as possible.

  In the air purification apparatus 3 configured as described above, as shown in FIG. 7, the contaminated air E1 is taken into the outer shell body 41 of the cleaning unit 4 from the duct 31, and the three-stage filler unit 10 (101, 102). , 103). At this time, on the surface of each filler 1 in each filler unit 10, the granular liquid agent T sprayed from the watering nozzle 43 adheres to form a water film on the surface, and the contaminated air passing through the filler 1 E1 efficiently makes gas-liquid contact with this water film, and the pollutant in the contaminated air E1 moves to the liquid agent T forming the water film. Furthermore, the contaminated air E1 that has passed through the three-stage filler units 101, 102, and 103 in order from the bottom to the top is directly in gas-liquid contact with the granular liquid T sprayed from the sprinkling nozzle 43 again. Contaminants remaining in the air E1 migrate and the contaminated air E1 is purified.

  Next, the purified air E <b> 2 purified through these steps collects droplets of the liquid T by the demister 42 and is exhausted outward from the opening 41 a of the outer shell body 41 by the exhaust fan 32. Then, the sprayed medicine T flows down not only the inner wall of the outer shell body 41 but also the demister 42, the watering nozzle 43, and the filler 1, is primarily stored in the liquid tank 45, and is drained through the drain pipe 45a. .

  Thus, in this Embodiment, the filler unit 10 with a large specific surface area can be formed by laminating | stacking the surface of the filler 1 in which the waveform was formed. Then, by providing the filler unit 10 in the cleaning unit of the air purification device 3, the medicine T sprayed in the cleaning unit 4 adheres to form a water film on the surface, and the filler 1 is applied to the water film. Since the polluted air E1 passing through is efficiently in gas-liquid contact, the pollutant in the polluted air E1 can be transferred into the water film and removed. And since the filler 1 uses the plastic mesh 12 for the cloth 11, it can be united by fusing with the cloth 11 by heating the plastic mesh 12, and it is easy compared with the filler by sewing. Can be manufactured.

As described above, in the filler, the filler manufacturing apparatus, and the filler manufacturing method according to the present embodiment, the filler 1 can be formed by fusing the plastic mesh 12 to the fabric 11 by fusing. It can be manufactured by a simple operation that is less time-consuming than a conventional filler by sewing.
In addition, since the mesh material is plastic, the material cost can be reduced and the weight can be reduced as compared with, for example, the case where a stainless steel mesh is used. Therefore, a plurality of fillers 1, 1,. The support structure (namely, unit case 13) of the made filler unit 10 made simple can be simplified, and the cost of the support structure can be held down.

  Next, test examples supporting the effects of the filler, the filler manufacturing apparatus, and the filler manufacturing method according to the above-described embodiment will be described below.

Example 1
Polyester cloth (fabric) and polypropylene mesh (plastic mesh) are fused to produce a vertical corrugated filler, and a large number of these fillers are stacked to form a filler unit. The air purification shown in FIG. An example in which acetic acid, which is a malodorous substance, is removed using an apparatus is shown.

First, the manufacture of the vertical corrugated filler will be described.
Using the bending apparatus shown in FIG. 5, both ends of a polyester cloth and a polypropylene mesh (hereinafter referred to as PP mesh) are fused with an iron, and the fused ends are an upper wave roll and a lower wave roll. It sent out toward the crimping | compression-bonding part which meshes. As a result, only the front side is aligned in the sending direction of the polyester cloth and PP mesh, and even if the polyester cloth and PP mesh with different materials and different thermal expansion coefficients are fused and bent, the downstream side of the crimping part is Since the polyester cloth and the PP mesh are not bonded, a corrugation that deeply curves in accordance with the corrugations of both rolls could be formed. That is, it was confirmed that the PP mesh contracts due to the fusion at the crimping part, but can be continuously bent with a deep waveform without being affected by it.

  In addition, the polyester cloth with the end fused is set on a table, the temperature of the upper wave roll is set to 80 ° C., and the temperature of the lower wave roll is set to 170 ° C. By rotating both rolls while inserting, a uniform filler with a corrugated height of 5 to 6 mm can be produced, and the fused state (adhered state) between the polyester cloth and the PP mesh was also good. . From this, it turns out that the bending apparatus by rotation is suitable.

Next, the manufactured filler was provided in an air purification device, and the effect of removing contaminants was confirmed.
The produced filler is approximately 300 mm square, and a filler unit is created by inserting a flat cloth between the fillers as shown in FIG. 4, and this unit is stacked in three stages as shown in FIG. As shown, the upper and lower adjacent filler units are arranged by shifting the installation angle by 90 degrees in plan view.
The operating conditions of the cleaning unit of the air purification apparatus shown in FIG. 7 are as follows: the inner diameter of the outer shell is 300 mm square, the amount of exhaust gas is 6.3 to 7.8 m ³ / min, and the wind speed in the tower (outer shell) is 1. 2 to 1.5 m / sec, the amount of water sprayed to the drug was 1 to 4 liters / minute, and the liquid gas ratio was 0.1 to 0.5 liters / m ³ . In addition, the sprinkling sprinkles clean tap water in the whole amount corresponding to the liquid gas ratio, and does not sprinkle circulating water. The inlet concentration of acetic acid was 10 to 500 mg / m ³ .
The acetic acid removal rate under these conditions was 90% or more, and when the liquid gas ratio was 0.3 liter / m ³ or more, it was 99% or more, and it was confirmed that the odor of the outlet air was almost eliminated. The pressure loss of the packing material was 100 Pa at the tower inner wind speed of 1.2 m / sec, and 200 Pa at 1.5 m / sec.

Further, as a comparative example, a commercially available polypropylene net ring (N-1, manufactured by Dainippon Plastics Co., Ltd.) is provided at 900 mm, which is the same height as the three-stage filler unit, and the wind speed in the tower is 1.2. The removal experiment was performed under the conditions of ˜1.5 m / sec and the liquid gas ratio of 0.57 to 0.67 liter / m ³ . As a result, the acetic acid removal rate was about 90%, and the pressure loss was 100 to 200 Pa, which was equivalent to that of the example.
That is, it was found that the filler of the example can obtain a high removal rate even though the liquid gas ratio is smaller than that of the filler of the comparative example. The specific surface area of the filler of the example was 720 m <2> / m < ³ >, thereby increasing the gas-liquid contact efficiency and reducing air resistance and low pressure loss. In the normal cleaning section, the liquid gas ratio is operated at 2 liter / m ³ or more, but in the cleaning section according to the present embodiment, the liquid gas ratio is 0.5 liter / m ^3, which is about 1/4. It was confirmed that a high removal rate was obtained with the pump power.

(Example 2)
Next, Example 2 shows an example in which vinylon is adopted as the material of the fabric.
A filler in which the vinylon cloth and the PP mesh were integrated by fusion was manufactured under the same conditions (upper wave roll temperature 80 ° C., lower wave roll temperature 170 ° C.) as in Example 1 described above.
This cleaning material is filled in the cleaning section shown in FIG. 5 only to a filling height of 300 mm, the exhaust gas amount is 6.3 to 9.5 m ³ / min, the tower wind speed is 1.2 to 1.9 m / second, and the water spray amount is 1. A removal experiment was performed under the conditions of 4 to 4 liters / minute, a liquid gas ratio of 0.4 to 0.5 liters / m ³ , and an acetic acid inlet concentration of 10 to 20 mg / m ³ . As a result, the acetic acid removal rate was 91 to 93%.

Next, as a comparative example, the same polypropylene net ring (N-1, manufactured by Dainippon Plastics Co., Ltd.) as in Example 1 was set to 900 mm, which is three times as high as the Example, and the wind speed in the tower was 1 The acetic acid removal rate was 90% under the conditions of 2 to 1.5 m / sec and the liquid gas ratio of 0.57 to 0.67 liter / m ³ .
Thereby, in Example 2, since it can be confirmed that the height of the filler has reached the same removal rate while being approximately 1/3 of the comparative example, the thickness of the filler can be reduced, The cost of the member can be reduced.

The embodiments of the filler, the filler manufacturing apparatus, and the filler manufacturing method according to the present invention have been described above. However, the present invention is not limited to the above-described embodiments, and does not depart from the spirit of the present invention. It can be changed as appropriate.
For example, the material of the fabric 11 and the plastic mesh 12 is not particularly limited as long as the conditions of the above-described embodiment are satisfied. In addition, when the fabric 11 and the plastic mesh 12 are made of polypropylene (PP) and are made of the same material, the expansion coefficient and the melting point are the same, so that it is difficult to perform the fusion using the folding device. In this case, for example, a PP cloth is placed on a PP mesh, a point cloth is fused with a soldering iron at an interval of, for example, 30 mm, and an integrated flat cloth is created in advance, and the flat cloth is folded without being heated by a bending device. By bending, a filler having a sufficient depth can be produced.

Further, the temperature control in the upper wave roll 21 and the lower wave roll 22 of the bending device 2 is not limited to the above-described embodiment. For example, the numbers and positions of the heaters 23 and 24 and the cooling nozzles 25 and 26 provided on the wave rolls 21 and 22 can be changed or omitted.
Furthermore, by connecting a motor for automatic rotation to one side of the upper wave roll 21 or the lower wave roll 22 via a gear, the bending process can be automated.
