本発明は、冷却塔（クーリングタワー）等において設備冷却後の循環温水を大気との熱交換で冷却するフィルムシートを組み合わせた水膜式充填材に関するものである。 The present invention relates to a water film type filler that is combined with a film sheet for cooling circulating hot water after equipment cooling in a cooling tower (cooling tower) or the like by heat exchange with the atmosphere.
冷却塔は、一般的に図４に示すように、冷却塔本体３１の内部にファン３２と、その下方に、ノズル３３と、さらにその下方に充填材ユニット３４が設置された構造となっている。そして、ノズル３３から循環温水が散水され、充填材ユニット３４中を下方に流下する間に、空気と冷却水が接触して、熱交換が行われる。 As shown in FIG. 4, the cooling tower generally has a structure in which a fan 32 is provided in the cooling tower body 31, a nozzle 33 is provided below the fan 32, and a filler unit 34 is further provided below the fan 32. . Then, while circulating hot water is sprinkled from the nozzle 33 and flows down in the filler unit 34, the air and the cooling water come into contact with each other to perform heat exchange.
このような、冷却塔の充填材ユニット３４には、近年、充填材フィルムシート１を所定間隔で複数枚積層したブロックが、多く用いられている。該充填材フィルムシート１の材質は、硬質ポリ塩化ビニルのフィルムが一般的で、該フィルムを所定の形状に真空成形して、単位充填材フィルムシート１が成形される。図２に充填材フィルムシート１を積層した状態を示す。充填材フィルムシート１には、凸部３が形成されており、この凸部３に接着材を塗布して、充填材フィルムシート１を順次接着し、積層して、略ハニカム状とし、およそ、１ｍ３ほどの立方体のユニットが形成される。そして、該ユニットが冷却塔内に設置される。 In recent years, a block in which a plurality of the filler film sheets 1 are laminated at a predetermined interval is often used for the filler unit 34 of the cooling tower. The material of the filler film sheet 1 is generally a hard polyvinyl chloride film, and the unit filler film sheet 1 is formed by vacuum forming the film into a predetermined shape. FIG. 2 shows a state where the filler film sheet 1 is laminated. The filler film sheet 1 has a convex portion 3, and an adhesive is applied to the convex portion 3. The filler film sheet 1 is sequentially adhered and laminated to form a substantially honeycomb shape. A cubic unit of about 1 m 3 is formed. And this unit is installed in a cooling tower.
充填材フィルムシート１を使った積層方法で接着材塗布以外の接合方法としては、

In Patent Document 1, a convex portion and a hole portion are provided on the plate surface of the plate-like body at intervals, the convex portion is press-fitted into the hole portion, and a locking portion provided at the tip of the convex portion is the periphery of the hole portion. A laminating technique that engages in
Patent Document 2 discloses a technique in which a PET film is formed into a waveform in which crests and troughs are alternately provided, and is fitted and laminated by fitting means provided in crests and troughs.
In Patent Document 3, a plastic filler sheet A in which a large number of protruding portions are formed is overlaid with another filler sheet B via the protruding portions, and the filler sheets are placed together using an ultrasonic oscillator.

Patent Document 4 discloses a technique for heating and pressing a small hollow convex portion for fitting when laminating a thermoplastic synthetic resin filler having a large hollow convex portion for holding a gap and a small hollow convex portion for fitting. Yes.
しかしながら、上記した積層手段は、機械的手段や超音波、加熱押圧手段により嵌合するので、充填材の製造にコストがかかり、更に積層方法も複雑である。一方、有機溶剤型接着材を用いた場合には、溶剤が揮発するので、取り扱いに注意を要し、また臭気等の作業環境が問題となる。更には、充填剤フィルムシート一枚毎に接着剤を塗布するので、接着加工作業が煩雑であり、非効率であるという問題があった。
However, the above-described laminating means is fitted by mechanical means, ultrasonic waves, or heating and pressing means, so that it is expensive to manufacture the filler and the laminating method is also complicated. On the other hand, when an organic solvent type adhesive is used, the solvent is volatilized, so that care is required for handling, and the working environment such as odor becomes a problem. Furthermore, since the adhesive is applied to each filler film sheet, there is a problem that the bonding process is complicated and inefficient.
発明者等は、上記した課題を解決するため鋭意検討を重ねて、本願発明に至ったもので、本発明の特徴は以下の通りである。 The inventors have intensively studied in order to solve the above-described problems and have arrived at the present invention. The features of the present invention are as follows.
（１）第一の発明は、複数枚の充填材フィルムシートを、各々間隔をおいて積層した冷却塔の充填材ユニットにおいて、前記充填材フィルムシートは、片面側に間隔をおいて複数の凸部と複数の貫通孔を有して積層され、連結チューブが前記貫通孔を挿通して前記充填材フィルムシートと係合されていることを特徴とする冷却塔の充填材ユニットである。 (1) A first invention is a cooling tower filler unit in which a plurality of filler film sheets are laminated at intervals, and the filler film sheet has a plurality of protrusions spaced on one side. And a plurality of through holes, and a connecting tube is inserted through the through hole and engaged with the filler film sheet.
（２）第二の発明は、連結チューブが熱可塑性樹脂からなることを特徴とする発明一に記載の冷却塔の充填材ユニットである。 (2) The second invention is the filler unit of the cooling tower according to the first invention, wherein the connecting tube is made of a thermoplastic resin.
（３）第三の発明は、片面側に一定間隔をおいて複数の凸部を有する充填材フィルムシートの４隅および中央部に貫通孔を設けた後、前記フィルムシートを貫通孔の位置を合わせて積層し、各貫通孔に連結チューブを挿通する。続いて、挿通された該連結チューブを熱風あるいは、蒸気による加熱手段により、所定の温度に保持かつ連結チューブ内側を加圧して、チューブ径を拡大した後に冷却し、前記連結チューブと前記充填材フィルムシートとの間に締付力を発生させることを特徴とする冷却塔の充填材ユニットの製造方法である。
(3) In the third invention, after the through holes are provided in the four corners and the center of the filler film sheet having a plurality of convex portions at a constant interval on one side, the position of the through holes is set on the film sheet. Laminate together and insert the connecting tube through each through hole. Subsequently, the inserted connecting tube is maintained at a predetermined temperature by hot air or steam heating means, the inside of the connecting tube is pressurized, the tube diameter is expanded and then cooled, and the connecting tube and the filler film A method for producing a filler unit for a cooling tower, wherein a clamping force is generated between the sheet and a sheet.
本発明の積層手段は、複雑な嵌合手段や接着材を使用せず、簡単確実に積層できるので、作業環境の向上、作業効率の向上が可能となる。
Since the laminating means of the present invention can be laminated easily and reliably without using complicated fitting means and adhesives, it is possible to improve the working environment and work efficiency.
本発明の冷却塔の充填材ユニット３４は、積層された充填材フィルムシート１の連結材として、熱可塑性チューブ２が、充填材フィルムシート１を均等に連結保持できるように、充填材フィルムシート１を貫通保持しているので、それぞれの充填材フィルムシート１を積層する際は、充填材フィルムシート１表面の凸部に係止機能を必要とせず、また接着材での接着も必要としない。
連結チューブ２の形状は、筒状で長手方向端部は開口しているが、片端はフランジ等で閉じられていてもよい。連結チューブ２は、熱可塑性樹脂を使用しているので、その筒状部の外径は、加熱・加圧されて拡径し、充填材フィルムシート１の貫通穴と密着して接合する。
The filler unit 34 of the cooling tower of the present invention is a filler film sheet 1 so that the thermoplastic tube 2 can evenly hold the filler film sheet 1 as a connecting material for the laminated filler film sheets 1. Therefore, when the respective filler film sheets 1 are laminated, the protrusions on the surface of the filler film sheet 1 do not require a locking function and do not require bonding with an adhesive.
The shape of the connecting tube 2 is cylindrical and the end in the longitudinal direction is open, but one end may be closed by a flange or the like. Since the connecting tube 2 uses a thermoplastic resin, the outer diameter of the cylindrical portion is heated and pressurized to expand the diameter, and is in close contact with the through hole of the filler film sheet 1 to be joined.
以下、本発明の一実施例を図面に基づいて説明する。図１―１は充填材フィルムシート１枚の連結用チューブの穴の位置の一例を示す図である。該フィルムシートの寸法は、0.4〜0.5mm厚 x 900mm幅 x 900mm長 くらいが一般的である。 Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1-1 is a diagram showing an example of the position of a hole in a connecting tube for one filler film sheet. The dimension of the film sheet is generally about 0.4 to 0.5 mm thick x 900 mm wide x 900 mm long.
連結用チューブ２を通す穴径は、３０〜５０ｍｍで充填材フィルムシートの４隅に各１個と中央部に１個加工する。穴の個数はシートのサイズにより変更し、通常５〜８個加工する。穴は、プレス加工により設けるのがよい。 The diameter of the hole through which the connecting tube 2 is passed is 30 to 50 mm, and one piece is processed at each of the four corners of the filler film sheet and one at the center. The number of holes is changed according to the size of the sheet, and usually 5 to 8 holes are processed. The holes are preferably provided by pressing.
図１―２に各充填材フィルムシート１をブロック形状に積層した側面図を示す。充填材フィルムシート１の片面側には循環温水が通過できる空間を確保するための凸部３が一定間隔で充填材フィルムシート１上に形成されている。１個の凸部の山高さは２５〜４５ｍｍ程度がよい。山高さが低すぎると充填材フィルムシートの間隔が狭くなりすぎ、循環温水がスムースに通過し難くなるからである。
１ブロックの組み立て寸法は、概ね900mm幅 x 900mm長 x 900mm高 位である。
連結チューブ２用穴は充填材フィルムシート１を積層する時の位置合わせ用としても、使用可能である。
連結チューブ２はカシメ効果を出すために、熱可塑性樹脂を使用する。熱可塑性樹脂とは、常温では変形しにくいが、適当な温度に加熱すると軟化し、粘性流動が起こるため変形しやすくなり、外力を加えて連結チューブ１のチューブ径を拡大した後、冷却し、外力を取り去っても、その外径が保持される性質を有する樹脂である。この一連の変化は可逆的であり、繰り返し行うことが可能である。また、冷却固化すれば十分な強度を有する樹脂である。
FIG. 1-2 shows a side view of the filler film sheets 1 laminated in a block shape. On one side of the filler film sheet 1, convex portions 3 are formed on the filler film sheet 1 at regular intervals to ensure a space through which the circulating hot water can pass. The peak height of one protrusion is preferably about 25 to 45 mm. This is because if the peak height is too low, the interval between the filler film sheets becomes too narrow, and the circulating hot water does not pass smoothly.
The assembly dimensions of one block are approximately 900mm wide x 900mm long x 900mm high.
The hole for the connection tube 2 can also be used for positioning when the filler film sheet 1 is laminated.
The connecting tube 2 uses a thermoplastic resin in order to produce a caulking effect. Thermoplastic resin is hard to deform at room temperature, but softens when heated to an appropriate temperature, and is easily deformed because viscous flow occurs. After applying an external force to expand the tube diameter of the connecting tube 1, it is cooled, Even if the external force is removed, the resin has a property that the outer diameter is maintained. This series of changes is reversible and can be repeated. Further, it is a resin having sufficient strength when cooled and solidified.
熱可塑性樹脂としては、ポリエチレン（PE）、ポリプロピレン（PP）、ポリ塩化ビニル（PVC）ポリスチレン（PS）、アクリロニトリル−ブタジエン−スチレン共重合樹脂（ABS）、アクリロニトリル−スチレン共重合樹脂（AS）等の汎用樹脂を使うことが出来る。 Examples of thermoplastic resins include polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC) polystyrene (PS), acrylonitrile-butadiene-styrene copolymer resin (ABS), and acrylonitrile-styrene copolymer resin (AS). General-purpose resin can be used.
図１―２に示すように充填材フィルムシート１を積層し、連結チューブ２を挿入して、１ブロックの組み立てを行った後、連結チューブ２の内面を加熱し、連結チューブ２の外径を所定寸法に膨張拡大した後冷却する。連結チューブ２は熱可塑性樹脂を使用したので膨張拡大した外径で固定されるが、充填材フィルムシート１は熱変形が少ないのでカシメ効果が生じて充填材フィルムシート１はブロックとして組み立て固定される。 As shown in FIG. 1-2, after laminating the filler film sheet 1, inserting the connecting tube 2 and assembling one block, the inner surface of the connecting tube 2 is heated, and the outer diameter of the connecting tube 2 is reduced. It cools after expanding and expanding to a predetermined dimension. Since the connecting tube 2 uses a thermoplastic resin and is fixed with an expanded and expanded outer diameter, the filler film sheet 1 is less deformed by heat, so that a caulking effect is produced and the filler film sheet 1 is assembled and fixed as a block. .
図３に連結チューブ２と充填材フィルムシート１との接合作業方法および必要器具を示す。ベース１７の上に接合する充填材フィルムシート１を１ブロック枚数分積層する。尚充填材フィルムシート１の連結チューブ２の貫通穴には連結チューブ２を挿入しておく。 FIG. 3 shows a method for joining the connecting tube 2 and the filler film sheet 1 and necessary equipment. One block of the filler film sheet 1 to be bonded is laminated on the base 17. The connecting tube 2 is inserted into the through hole of the connecting tube 2 of the filler film sheet 1.
次に、加熱ノズル４ａを連結チューブ２内に挿入する。加熱ノズル４ａには、***４ｂが多数あけてあり、ここより熱風及び冷風を供給する。加熱ノズル４ａは上蓋４ｃと一体になっており、下蓋４ｃと共に、連結チューブ２内の加圧時にカ゛ス漏れを防ぐようになっている。加熱ノズル４ａは、連結チューブ２の数（５〜８個）だけ設置しサポート板１５に固定して使用する。 Next, the heating nozzle 4 a is inserted into the connecting tube 2. The heating nozzle 4a has a large number of small holes 4b through which hot air and cold air are supplied. The heating nozzle 4a is integrated with the upper lid 4c, and together with the lower lid 4c, gas leakage is prevented when the connection tube 2 is pressurized. The heating nozzles 4a are installed by the number (5 to 8) of the connecting tubes 2 and fixed to the support plate 15 for use.
サポート板１５はサポート柱１６ａを介してベース１７と結合され、サポート柱１６ａは積層した充填材フィルムシート１の角隅部４箇所に設置する。サポート柱１６ａの上端部はネジとなっており、ナット１６ｂを締め込むことにより蓋４ｃを連結チューブに強固に押しつけることができる。 The support plate 15 is coupled to the base 17 via the support columns 16a, and the support columns 16a are installed at four corners of the laminated filler film sheet 1. The upper end portion of the support column 16a is a screw, and the lid 4c can be firmly pressed against the connecting tube by tightening the nut 16b.
上部蓋４ｃには、放風ノズル５及び放風弁６が接続されており、連結チューブ２を加熱・冷却する時に、熱風及び冷風の排出口となる。放風弁６の開度は予め熱風及び冷風通気時に連結チューブ２内の圧力を適正に保てる開度に調整しておく必要がある。尚、下部蓋４ｃは、熱風、冷風が漏れないように設置したもので、連結チューブ２の下端部をフランジ等により閉じた構造としてもよい。 An air discharge nozzle 5 and an air discharge valve 6 are connected to the upper lid 4c, and serve as an outlet for hot air and cold air when the connecting tube 2 is heated and cooled. The opening degree of the discharge valve 6 needs to be adjusted in advance to an opening degree that can keep the pressure in the connecting tube 2 properly when hot air and cold air are ventilated. The lower lid 4c is installed so that hot air and cold air do not leak, and the lower end portion of the connecting tube 2 may be closed by a flange or the like.
ブロワ１１で大気を吸込み昇圧して、熱交換器１０ａに導管１２を介して供給する。熱交換器１０ａはヒーター１０ｂ（電気式又は蒸気式）を熱限とし、熱風を供給される。熱風は、熱風自動弁７を開とすることで導管１４にて、加熱ノズル４ａに供給される。この時冷風自動弁８は閉状態とする。 The blower 11 sucks in the atmosphere and pressurizes it to supply it to the heat exchanger 10a through the conduit 12. The heat exchanger 10a has a heater 10b (electric type or steam type) as a heat limit and is supplied with hot air. Hot air is supplied to the heating nozzle 4a through the conduit 14 by opening the hot air automatic valve 7. At this time, the cold air automatic valve 8 is closed.
熱風の供給温度は熱可塑性樹脂製の連結チューブ２を軟化させる温度である６０〜１００℃とするのがよい。この温度は、加熱時に充填材フィルムシート１は熱変形せずに、連結チューブ２のみが外径が拡大して充填材フィルムシート１とカシメ効果をもたせるもので、熱可塑性樹脂としては、エンジニアリング樹脂よりもポリエチレン等の汎用樹脂が好ましい。 The supply temperature of the hot air is preferably 60 to 100 ° C., which is a temperature for softening the connecting tube 2 made of thermoplastic resin. This temperature is such that the filler film sheet 1 is not thermally deformed during heating, and only the connecting tube 2 is expanded in outer diameter to have a caulking effect with the filler film sheet 1. As a thermoplastic resin, an engineering resin is used. A general-purpose resin such as polyethylene is preferred.
熱風自動弁７及び冷風自動弁８の２次側には、減圧弁９が設置されており、加熱ノズル４ａへの供給圧力を適正に調整出来るようになっている。供給圧力は、加熱により軟化した連結チューブ２を拡径させる圧力でよく５ｋＰａ〜２０ｋＰａとするのがよい。 A pressure reducing valve 9 is installed on the secondary side of the hot air automatic valve 7 and the cold air automatic valve 8 so that the supply pressure to the heating nozzle 4a can be adjusted appropriately. The supply pressure may be a pressure for expanding the diameter of the connecting tube 2 softened by heating, and is preferably 5 kPa to 20 kPa.
加熱ノズル４ａの***４ｂより噴出した熱風は連結チューブ２を加熱軟化させる。ここで、均一に加熱軟化させるために、放出弁６を介して放出ノズル５より連続的に排風する。これにより、連結チューブ２は同時に加熱及び加圧されて、拡径し、充填材フィルムシート１と密着する。 Hot air ejected from the small hole 4b of the heating nozzle 4a softens the connecting tube 2 by heating. Here, in order to heat and soften uniformly, the air is continuously exhausted from the discharge nozzle 5 through the discharge valve 6. Thereby, the connection tube 2 is heated and pressurized simultaneously, expands in diameter, and adheres to the filler film sheet 1.
次に、熱風自動弁７を閉、冷風自動弁８を開とすることで、冷風を連結チューブ２に供給する。加圧状態のまま熱風から冷風に切替るので、連結チューブ２は拡径状態を維持したまま元の硬さに硬化し、充填材フィルムシート１の連結チューブ２用の穴とのカシメ効果で、充填材フィルムシート１と結合する。
Next, the hot air automatic valve 7 is closed and the cold air automatic valve 8 is opened, whereby the cold air is supplied to the connecting tube 2. Since switching from hot air to cold air in the pressurized state, the connection tube 2 is cured to the original hardness while maintaining the expanded diameter state, and with a caulking effect with the hole for the connection tube 2 of the filler film sheet 1, Combined with the filler film sheet 1.
