Description

本発明は、例えばエアコンプレッサ等から供給されたエアータンク内の圧縮空気を気液分離器へ供給する際に好適で、冷凍式エアードライヤを廃し、圧縮空気を簡単かつ安価な方法で冷却して除湿ないし乾燥状態を形成し、この乾燥空気を気液分離器へ供給して気液分離を高精度かつ能率良く行ない、これを使用するエアーツールの故障や機能低下を防止するとともに、気液分離器を屋内外の所望位置に簡便かつ安全に設置できるようにした、気液分離器用圧縮空気の冷却方法およびその冷却装置並びに気液分離器の収納装置に関する。   The present invention is suitable for supplying compressed air in an air tank supplied from, for example, an air compressor to a gas-liquid separator. The refrigeration air dryer is eliminated, and the compressed air is cooled by a simple and inexpensive method. Form a dehumidified or dry state, supply this dry air to the gas-liquid separator to perform gas-liquid separation with high accuracy and efficiency, and prevent the air tool that uses it from malfunctioning or function deterioration, and gas-liquid separation TECHNICAL FIELD The present invention relates to a method for cooling compressed air for a gas-liquid separator, a cooling device for the same, and a storage device for a gas-liquid separator, which can be easily and safely installed at desired positions indoors and outdoors.

エアコンプレッサから吐出された圧縮空気には水や油分が混在し、この圧縮空気をエアードライバーやインパクトレンチ、塗装ガン等のエアーツールへ供給すると、空気導管の内部が錆たり、エアーツール内部の構成部品が錆びて機能が低下し故障を起こす惧れがあるため、圧縮空気の吐出管路にエアードライヤである気液分離器を取付けて水分を除去し、乾燥した圧縮空気をエアーツールへ供給するようにしている。   The compressed air discharged from the air compressor contains water and oil, and if this compressed air is supplied to an air tool such as an air driver, impact wrench, or paint gun, the inside of the air conduit will rust, or the internal structure of the air tool Since parts may rust and malfunction and may cause malfunctions, a gas-liquid separator as an air dryer is attached to the compressed air discharge line to remove moisture, and dry compressed air is supplied to the air tool. I am doing so.

前記気液分離器は、例えば中空円筒体の上部に中空円筒体の内部に連通する 上カバーを取付け、該カバーの両側に設けた入口通路と出口通路に圧縮空気の管路を形成する導管をねじ込み、中空円筒体の内部に中空円筒状の仕切管を配置し、該仕切管の内部に凸部と凹み空間とこれらを貫通する透孔を形成した気液分離部材である複数の仕切り構造を積み重ねて配置している。
そして、前記入口通路から中空円筒体内に導入した圧縮空気を、複数の仕切り構造の下方に導いて透孔から噴出し、その断熱膨張により凝結した水分を中空円筒体の下端部に設けたドレン孔（図示略）から排出し、水分を除去し乾燥した空気を出口通路から排出して、エアーツール側へ供給するようにしている（例えば、特許文献１参照）。 In the gas-liquid separator, for example, an upper cover communicating with the inside of the hollow cylindrical body is attached to an upper portion of the hollow cylindrical body, and a conduit for forming a compressed air conduit is formed in an inlet passage and an outlet passage provided on both sides of the cover. A plurality of partition structures, which are gas-liquid separation members, are screwed, a hollow cylindrical partition tube is disposed inside the hollow cylindrical body, and a convex portion, a recessed space, and a through-hole penetrating these are formed inside the partition tube. They are stacked.
Then, the compressed air introduced into the hollow cylindrical body from the inlet passage is guided to the lower side of the plurality of partition structures and ejected from the through-hole, and the water condensed by the adiabatic expansion is provided at the lower end of the hollow cylindrical body. The air that has been discharged from (not shown), removed moisture, and dried is discharged from the outlet passage and supplied to the air tool (see, for example, Patent Document 1).

しかし、前記気液分離器は圧縮空気の吐出管路に介挿して使用され、その吐出管路は通常は工場等の屋内に配置されているため、気液分離器の設置位置や利用箇所が限られてしまう問題があった。
また、吐出管路の上流または中流側に気液分離器を介挿して気液分離しても、エアーツールへ供給する際は周辺の空気温度によって再度水分が凝縮して混入し、当初の気液分離状態が低下して水分が混在した圧縮空気をエアーツールへ供給してしまい、エアーツールが故障したり機能が低下し、または塗装ガンのように所期の塗装が不可能になって使用不能に陥る等の問題があった。 However, since the gas-liquid separator is used by being inserted into a discharge pipe for compressed air, and the discharge pipe is usually arranged indoors in a factory or the like, the installation position and use location of the gas-liquid separator are There was a limited problem.
In addition, even if gas-liquid separation is performed by inserting a gas-liquid separator upstream or midstream of the discharge pipe, when water is supplied to the air tool, moisture is condensed and mixed again due to the ambient air temperature. Compressed air mixed with moisture due to a decrease in liquid separation condition is supplied to the air tool, causing the air tool to fail or functioning poorly, or making it impossible to perform the desired painting like a paint gun There was a problem of falling into impossibility.

ところで、気液分離器によって圧縮空気を能率良く高精度に気液分離する場合は、冷却し乾燥した圧縮空気を気液分離器へ供給することが望しく、この要請に応ずるものとして、例えばエアコンプレッサの圧縮空気を冷凍式エアードライヤへ送り込み、該冷凍式エアードライヤは、エアードライヤ本体ケース内に、圧縮機と凝縮器と冷却器からなる冷凍回路を配置し、その冷却室に前記圧縮空気を送り込んで冷却し乾燥するようにしたものがある（例えば、特許文献２，３参照）。   By the way, when the compressed air is efficiently and accurately separated by the gas-liquid separator, it is desired to supply the cooled and dried compressed air to the gas-liquid separator. Compressed air from the compressor is sent to a refrigeration air dryer. The refrigeration air dryer has a refrigeration circuit including a compressor, a condenser, and a cooler arranged in the air dryer body case, and the compressed air is supplied to the cooling chamber. Some have been fed, cooled and dried (see, for example, Patent Documents 2 and 3).

しかし、冷凍式エアードライヤは設置に費用が掛かる上に、エアーツールの使用時は冷凍式エアードライヤを終始駆動するため、その運転費用が膨大になるという問題があった   However, the refrigeration air dryer is expensive to install, and when the air tool is used, the refrigeration air dryer is driven all the time.

そこで、前記問題を解決するものとして、エアードライヤの内部に冷凍回路を構成する第１および第２熱交換器を配置し、これらの熱交換器に冷媒を供給し、第１熱交換器に導入した冷却水を冷却して第２熱交換器へ導入し、この第２熱交換器に圧縮空気を導入し、該圧縮空気を前記冷却水で冷却するようにしたエアードライヤがある（例えば、特許文献４参照）。   In order to solve the above problem, the first and second heat exchangers constituting the refrigeration circuit are arranged inside the air dryer, the refrigerant is supplied to these heat exchangers, and the refrigerant is introduced into the first heat exchanger. There is an air dryer in which the cooled water is cooled and introduced into the second heat exchanger, compressed air is introduced into the second heat exchanger, and the compressed air is cooled with the cooling water (for example, a patent) Reference 4).

しかし、このエアードライヤは冷却水の冷却を要し、そのための第１および第２熱交換器を備えた冷凍回路の設置を要して、その設備費とその運転費用が嵩む等の問題があった   However, this air dryer requires cooling of the cooling water and requires the installation of a refrigeration circuit including the first and second heat exchangers for that purpose, resulting in problems such as increased equipment costs and operating costs. The

また、圧縮空気を水冷する他の手段として、エアコンプレッサの圧縮空気を導入する圧縮空気管を冷却水槽に配管し、該冷却水槽の底部に水冷式アフタークーラーを設け、該アフタークーラーに圧縮空気を導入して冷却し、冷却した圧縮空気を併設した冷凍式エアードライヤへ導き、その冷凍配管によって圧縮空気を更に冷却するようにしたものがある（例えば、特許文献５参照）。   As another means for cooling the compressed air with water, a compressed air pipe for introducing the compressed air of the air compressor is provided in the cooling water tank, a water-cooled aftercooler is provided at the bottom of the cooling water tank, and the compressed air is supplied to the aftercooler. There is one that is introduced and cooled, and the cooled compressed air is led to a refrigerating air dryer, and the compressed air is further cooled by the refrigerating pipe (see, for example, Patent Document 5).

しかし、この装置は水冷式アフタークーラーの他に冷凍式エアードライヤの併設を要し、それらの設備費が嵩む上にその運転費用が嵩み、しかも圧縮空気の冷却に時間が掛かる等の問題があった。   However, this device requires a refrigeration air dryer in addition to the water-cooled aftercooler, which increases the equipment costs and the operating costs, and also takes time to cool the compressed air. there were.

そして、気液分離器２９の下端部にドレン器３０の上端部をねじ込み、これらを気密に連結後、前述と同様に一対の支持金具２８の係止爪２８ｂ，２８ｂをガイドレール２６の係合縁２６ａ，２６ａに係合して、ドレン器３０を吊り下げる。
その際、気液分離器２９とドレン器３０に対する支持金具２７，２８の取付け位置を上下に調節して、気液分離器２９とドレン器３０の上下位置を調整し、また支持金具２７，２８の他端をガイドレール２５，２６に沿って摺動させて、ドライボックス６内における気液分離器２９とドレン器３０の前後位置を調整し、同時にそれらと導入管３５と排気管３７、圧力計測管３９，４０とドレン管５０との接触を防止する。 Then, after screwing the upper end portion of the drain device 30 into the lower end portion of the gas-liquid separator 29 and connecting them in an airtight manner, the engaging claws 28b, 28b of the pair of support fittings 28 are engaged with the guide rail 26 in the same manner as described above.

前記ドレン器３０の下端にドレン管５０の一端を接続し、その他端部をホースエンド５１に接続し、該ホースエンド５１にドレン溜（図示略）に連絡するドレンホース５２を接続する。
また、底面板１９の下面の四隅に脚５３の螺軸をねじ込み、前記折曲げ部１６ａ，１７ａ，１８ａ，１９ａに背面カバ−２０を重合し、これをビス止めしてドライボックス６の背面を閉塞する。 One end of a drain pipe 50 is connected to the lower end of the drain device 30, the other end is connected to a hose end 51, and a drain hose 52 connected to a drain reservoir (not shown) is connected to the hose end 51.
Further, the screw shafts of the legs 53 are screwed into the four corners of the bottom surface of the bottom plate 19, the back cover 20 is overlapped with the bent portions 16 a, 17 a, 18 a, 19 a, and this is screwed to secure the back surface of the dry box 6. Block.

こうして組み立てたドライボックス６は、内部に気液分離器２９やドレン器３０等を配置してそれらを保護しているから、例えばドライボックス６をエアータンク１から離隔した屋外に設置することも可能になり、気液分離器２９やドレン器３０等をエアーツール４９の使用環境に応じて工場の内外へ設置し得る。   Since the dry box 6 assembled in this way has a gas-liquid separator 29, a drain device 30 and the like disposed therein to protect them, for example, the dry box 6 can also be installed outdoors separated from the air tank 1. Thus, the gas-liquid separator 29, the drain device 30 and the like can be installed inside and outside the factory according to the use environment of the air tool 49.

次に、冷却槽４とドライボックス６を設置する場合は、エアータンク１の設置位置とエアーツール４９の使用位置とそれらの設置環境に応じて、屋内または屋外に設置する。
例えば前記冷却槽４をエアータンク１と離間する屋内または屋外の平坦な場所に設置し、前記冷却槽４から離間してドライボックス６を屋内または屋外の平坦な場所に設置し、該ドライボックス６から離間してエアーツール４９を配置する。
その際、冷却水を導入前の空状態の冷却槽４を、把手１４を保持して適宜位置へ持ち運び、所定の設置面７に設置する。また、把手２３を保持してドライボックス６を適宜位置へ持ち運び、所定の設置面７に設置する。 Next, when installing the cooling tank 4 and the dry box 6, it installs indoors or outdoors according to the installation position of the air tank 1, the use position of the air tool 49, and those installation environments.
For example, the cooling tank 4 is installed in an indoor or outdoor flat place away from the air tank 1, and the dry box 6 is installed in an indoor or outdoor flat place away from the cooling tank 4. The air tool 49 is disposed away from the air tool 49.
At that time, the cooling tank 4 in an empty state before introducing the cooling water is carried to an appropriate position while holding the handle 14 and installed on a predetermined installation surface 7. In addition, the handle 23 is held and the dry box 6 is carried to an appropriate position and installed on a predetermined installation surface 7.

実施形態ではドライボックス６を縦４７０〜５００ｍｍ、横３００〜３６０ｍｍ、奥行３００〜３６０ｍｍの比較的コンパクトに形成し、その重量を９〜１５ｋｇに構成しているから、人力によって容易に持ち運べ、設置の際は脚５３を回動操作して高さ調整し、設置面７に安定かつ水平に設置する。   In the embodiment, the dry box 6 is formed in a relatively compact size of 470 to 500 mm in length, 300 to 360 mm in width, and 300 to 360 mm in depth, and has a weight of 9 to 15 kg. At that time, the height of the leg 53 is adjusted by rotating the leg 53, and the leg 53 is stably and horizontally installed on the installation surface 7.

この場合、冷却槽４は内部に冷却管１３をコイル状に捲回して配置しているから、冷却管をジグザグ状に屈曲して配置する場合に比べ、冷却管１３の長尺化と冷却槽４の小形化ないし設置スペースのコンパクト化、並びに冷却能力の向上を図れる。
したがって、冷却槽４を大型化すればする程、冷却管１３の長尺化を図れ、冷却能力を向上し得るから、冷却槽４をドライボックス６とエアータンク１に近接して配置することができ、それらの設置スペースのコンパクト化を図れる。
しかも、本発明は冷却槽４の他に、冷却水の冷却装置や冷凍回路、冷凍式エアードライヤを要しないから、その分設備費の低減とその稼動費の削減を図れる。 In this case, since the cooling tank 4 is arranged by winding the cooling pipe 13 in a coil shape, the cooling pipe 13 is elongated and the cooling tank is compared with the case where the cooling pipe is bent and arranged in a zigzag shape. 4 can be downsized or the installation space can be made compact and the cooling capacity can be improved.
Therefore, the larger the cooling tank 4 is, the longer the cooling pipe 13 can be lengthened and the cooling capacity can be improved. Therefore, the cooling tank 4 can be arranged close to the dry box 6 and the air tank 1. The installation space can be made compact.
Moreover, since the present invention does not require a cooling water cooling device, a refrigeration circuit, or a refrigeration air dryer in addition to the cooling tank 4, the equipment cost and the operation cost can be reduced accordingly.

こうして、冷却槽４とドライボックス６を設置後、エアータンク１と冷却槽４とを空気導入管２を介して接続し、該導管２に調圧弁３を介挿するとともに、冷却槽４とドライボックス６とを空気導出管５を介して接続し、空気導出管５に装着したカプラ４６をインレット４２側のカプラ４４に連結し、更にアウトレット４３に装着したカプラ４５に空気供給管４７側のカプラ４８を接続し、該空気供給管４７の他端をエアーツール４９に接続し、ホースエンド５１にドレンホース５２を接続する。   Thus, after installing the cooling tank 4 and the dry box 6, the air tank 1 and the cooling tank 4 are connected via the air introduction pipe 2, the pressure regulating valve 3 is inserted into the conduit 2, and the cooling tank 4 and the dry box 6 are connected. The box 6 is connected via the air outlet pipe 5, the coupler 46 attached to the air outlet pipe 5 is connected to the coupler 44 on the inlet 42 side, and the coupler 45 attached to the outlet 43 is further connected to the coupler on the air supply pipe 47 side. 48, the other end of the air supply pipe 47 is connected to the air tool 49, and the drain hose 52 is connected to the hose end 51.

このような状況の下で開閉弁１０を開弁し開閉弁１１を閉弁して、水道水等の冷却水１２を給水管８から冷却槽４へ導いて貯留し、内部に配管した冷却管１３を冷却水１２中に没入させて冷却水１２の導入を停止後、エアータンク１内の圧縮空気を空気導入管２を介して冷却槽４へ導入する。
前記圧縮空気は、先ず冷却管１３のコイル状部１３ａに導かれて下方へループ状に移動し、冷却水１２によって冷却される。その際、コイル状部１３ａは直管状やこれを屈曲した配管に比べて長尺で、冷却水１２に対する接触面積が大きいから、圧縮空気の冷却が能率良く行なわれ、同時に圧縮空気の飽和蒸気圧が低下して除湿ないし乾燥が促される。 Under such circumstances, the on-off valve 10 is opened, the on-off valve 11 is closed, and the cooling water 12 such as tap water is led from the water supply pipe 8 to the cooling tank 4 and stored, and the cooling pipe piped inside 13 is immersed in the cooling water 12 and the introduction of the cooling water 12 is stopped, and then the compressed air in the air tank 1 is introduced into the cooling tank 4 through the air introduction pipe 2.
The compressed air is first guided to the coiled portion 13 a of the cooling pipe 13, moves downward in a loop shape, and is cooled by the cooling water 12. At that time, the coil-shaped portion 13a is longer than a straight tube or a pipe obtained by bending it, and has a large contact area with the cooling water 12. Therefore, the compressed air is efficiently cooled, and at the same time, the saturated vapor pressure of the compressed air. Lowers and promotes dehumidification or drying.

しかも、コイル状部１３ａでは圧縮空気に遠心力が働き、流速の大きい管中央部の圧縮空気に作用する遠心力は、管内壁付近の流速の小さい圧縮空気に作用する遠心力よりも大きいため、管中央部の圧縮空気は曲管部の外側へ押しやられ、管内壁付近の圧縮空気は内壁に沿って曲管部の内側に回り込む。
また、コイル状部１３ａの内壁面の圧力分布は、曲管部の外側が高く内側が低いため、管軸に垂直な断面に外側から内側へ回り込む一対の循環流が生ずる。
したがって、コイル状部１３ａを移動する圧縮空気は、遠心力による前述の作用と前記一対の循環流によって攪拌を促され、冷却温度が均一かつ一様になる。 Moreover, the centrifugal force acts on the compressed air in the coiled portion 13a, and the centrifugal force acting on the compressed air in the central portion of the pipe having a large flow velocity is larger than the centrifugal force acting on the compressed air having a small flow velocity near the inner wall of the tube. The compressed air at the center of the tube is pushed to the outside of the bent tube portion, and the compressed air near the inner wall of the tube wraps around the inner side of the bent tube portion along the inner wall.
Further, the pressure distribution on the inner wall surface of the coiled portion 13a is such that a pair of circulation flows that wrap around from the outside to the inside in a cross section perpendicular to the tube axis occurs because the outside of the curved pipe portion is high and the inside is low.
Therefore, the compressed air moving through the coiled portion 13a is urged to be stirred by the above-described action by the centrifugal force and the pair of circulation flows, and the cooling temperature becomes uniform and uniform.

こうして、コイル状部１３ａを移動する圧縮空気は、上部から下方へ移動するにつれて次第に冷却され、その最下位置から直管部１３ｂを上動する間も冷却水１２によって冷却されて空気導出管５へ送り出され、一様に冷却し乾燥した圧縮空気がドライボックス６へ導入される。この状況は図４のようである。   Thus, the compressed air that moves through the coiled portion 13a is gradually cooled as it moves downward from the upper portion, and is cooled by the cooling water 12 while moving up the straight pipe portion 13b from its lowest position, so that the air outlet pipe 5 Then, the compressed air that has been cooled and dried uniformly is introduced into the dry box 6. This situation is as shown in FIG.

すなわち、圧縮空気はインレット４２からドライボックス６に導入され、導管４１から三方ジョイント３６を経て導入管３５を移動し、上カバー３４の入口通路から気液分離器２９の内部に送り込まれて気液分離され、また気液分離前の一部の圧縮空気が圧力計測管４０に導かれて圧力計２２へ移動し、該圧力計２２によって導入空気圧が計測されて表示される。
そして、気液分離後の圧縮空気は、上カバー３４の出口通路から排気管３７へ送り出され、三方ジョイント３８から導管４１を経てアウトレット４３へ移動し、空気供給管４７に導かれてエアーツール４９へ供給される。 That is, compressed air is introduced from the inlet 42 into the dry box 6, moves from the conduit 41 through the three-way joint 36, moves through the introduction pipe 35, and is sent into the gas-liquid separator 29 from the inlet passage of the upper cover 34. Part of the compressed air that has been separated and before gas-liquid separation is guided to the pressure measuring tube 40 and moves to the pressure gauge 22, and the introduced air pressure is measured and displayed by the pressure gauge 22.
The compressed air after the gas-liquid separation is sent from the outlet passage of the upper cover 34 to the exhaust pipe 37, moves from the three-way joint 38 to the outlet 43 through the conduit 41, is guided to the air supply pipe 47, and is guided to the air tool 49. Supplied to.

その際、圧縮空気は冷却槽４で冷却され乾燥されて気液分離器２９に導入されるから、気液分離器２９における気液分離を能率良く速やかに行なえ、また水分を除去した乾燥状態の圧縮空気をエアーツール４９へ供給できるから、水分の混入によるエアーツール４９の機能低下や内部の錆の発生、故障を防止し得る。
なお、気液分離器２９で分離された油脂分、ゴミ等を含む凝縮水はドレン器３０に流下し、該ドレン器３０内のフィルタ等にろ過されてドレン管５０に導かれ、ホースエンド５１からドレンホース５２を経てドレン溜に排出される。 At that time, since the compressed air is cooled and dried in the cooling tank 4 and introduced into the gas-liquid separator 29, the gas-liquid separation in the gas-liquid separator 29 can be performed efficiently and promptly, and the dry state in which moisture is removed can be obtained. Since compressed air can be supplied to the air tool 49, it is possible to prevent deterioration of the function of the air tool 49 due to moisture mixing, generation of internal rust, and failure.
Condensed water containing fats and oils, dust and the like separated by the gas-liquid separator 29 flows down to the drain device 30, is filtered by a filter or the like in the drain device 30, is guided to the drain pipe 50, and the hose end 51. Is discharged to a drain reservoir through a drain hose 52.

一方、気液分離器２９やドレン器３０および他の構成部材が経時的に機能低下し、または故障して、それらを取替え若しくは整備点検するメンテナンス時は、ビス（図示略）を取外して背面カバー２０を取外し、ドライボックス６の背面を開放して、気液分離器２９やドレン器３０および他の構成部材を取外し新規部材と交換した後、背面カバー２０をビス止めして気液分離器２９やドレン器３０および他の構成部材の機能を復旧させる。
また、圧縮空気の気液分離後、適時、開閉弁１１を開弁して冷却槽４内の冷却水１２を排出し、冷却水１２の汚損や冷却管１３表面の異物の付着を防止し、その熱交換の低下を防止する。 On the other hand, the gas-liquid separator 29, the drain device 30 and other components are deteriorated in function over time or broken, and at the time of maintenance for replacing or servicing them, the screw (not shown) is removed and the back cover is removed. 20 is removed, the back of the dry box 6 is opened, the gas-liquid separator 29, the drain device 30 and other components are removed and replaced with new members, and the back cover 20 is screwed to fix the gas-liquid separator 29. The functions of the drain device 30 and other components are restored.
In addition, after the gas-liquid separation of the compressed air, the on-off valve 11 is opened at an appropriate time to discharge the cooling water 12 in the cooling tank 4 to prevent the cooling water 12 from being contaminated and foreign matter adhering to the surface of the cooling pipe 13. This prevents the heat exchange from decreasing.

この実施形態では、エアータンク１の圧縮空気を空気導入管２から冷却槽４の最上段のエアーチャンバ５５へ送ると、その導入部で断熱膨張して冷却され、同時にエアーチャンバ５５の内面下部に吹き付けられて圧縮空気中の水分を除去される。
この後、前記圧縮空気は噴口から分流してエアーチャンバ５５内を内周面に沿って円滑かつ速やかに移動し、前記噴口と対向する導管５６から排出されて直下のエアーチャンバ５５へ移動する。 In this embodiment, when the compressed air of the air tank 1 is sent from the air introduction pipe 2 to the uppermost air chamber 55 of the cooling tank 4, it is adiabatically expanded and cooled at the introduction portion, and at the same time, the inner surface of the air chamber 55 is The moisture in the compressed air is removed by spraying.
Thereafter, the compressed air is diverted from the nozzle and smoothly and quickly moves along the inner peripheral surface in the air chamber 55, and is discharged from the conduit 56 facing the nozzle and moves to the air chamber 55 immediately below.

前記直下のエアーチャンバ５５に導入された圧縮空気は、その導入部で断熱膨張して冷却され、同時にエアーチャンバ５５の内面下部に吹き付けられて圧縮空気中の水分を除去され、その圧縮空気が導管５６から分流してエアーチャンバ５５内を内面に沿って円滑かつ速やかに移動し、前記導管５６と対向する導管５６から排出されて直下のエアーチャンバ５５へ移動する。この状況は図９のようである。   The compressed air introduced into the air chamber 55 directly below is adiabatically expanded and cooled at the introduction portion, and at the same time, is sprayed on the lower part of the inner surface of the air chamber 55 to remove moisture in the compressed air. The air flow is diverted from 56 and smoothly and quickly moves along the inner surface in the air chamber 55, discharged from the conduit 56 facing the conduit 56, and moved to the air chamber 55 directly below.

Compressed air whose state has been improved is introduced into the dry box 6.
In this case, it is possible to add the air chamber 55 by omitting the coiled portion 13a of the cooling tank 4, and by doing so, the configuration can be simplified and the cooling capacity can be improved.

図１０および図１１は本発明の第５の実施形態を示し、この実施形態は第４の実施形態の応用形態を示している。この実施形態は第４の実施形態のエアーチャンバ５５を扁平な円筒体の代わりに、扁平な方形等の箱体に形成し、その内部の対向位置に一対の導管５６，５６を上向きまたは下向きに配置している。この場合、前述の実施形態のようにコイル状部１３ａを冷却槽４の下部または上部に配置しても良い。   10 and 11 show a fifth embodiment of the present invention, and this embodiment shows an application form of the fourth embodiment.

The compressed air is introduced into the dry box 6.

その際、エアーチャンバ５５を扁平な方形等の箱体に形成して、空気導入管２または導管５６から導入した圧縮空気の一部をエア−チャンバ５５の四隅に滞留させて、圧縮空気の移動速度を抑制し、抑制した圧縮空気をドライボックス６へ導入して気液分離器２９による気液分離作用を精密かつきめ細かに行なうようにしている。
図１１（ｂ）は図１１（ａ）の変形例で、空気導入管２と導管５６の位置をエアーチャンバ５５の対角線上に配置し、四隅部における滞留の形成を増進させて、前記抑制作用を向上させている。 At that time, the air chamber 55 is formed in a flat rectangular box or the like, and a part of the compressed air introduced from the air introduction pipe 2 or the conduit 56 is retained in the four corners of the air chamber 55 to move the compressed air. The speed is suppressed, and the suppressed compressed air is introduced into the dry box 6 so that the gas-liquid separator 29 performs the gas-liquid separation action precisely and finely.
FIG. 11 (b) is a modification of FIG. 11 (a), in which the positions of the air introduction pipe 2 and the conduit 56 are arranged on the diagonal line of the air chamber 55, and the formation of stays at the four corners is promoted, thereby suppressing the above-mentioned suppressing action. Has improved.

図１２は本発明の第６の実施形態を示し、この実施形態は冷却管１３の内径を移動域Ｚ1〜Ｚ3毎に移動方向に沿って大径管部と細径管部を交互に繰り返し、圧縮空気の断熱膨張と断熱圧縮を交互に行なって圧縮空気の冷却ないし降温と加温を交互に行ない、圧縮空気中の水蒸気の分布を粗密に調整するとともに、大径管部と細径管部を移動する圧縮空気の移動速度を減速または増速して、降温した圧縮空気中の粗状態の水蒸気をゆっくり移動させ、加温した圧縮空気中の密状態の水蒸気を速やかに移動させて、コイル状の冷却管１３による攪拌効果と相俟って、圧縮空気中の水蒸気の分布の均一化と安定化を図り、これを気液分離器２９へ送り出すようにしている。 FIG. 12 shows a sixth embodiment of the present invention. In this embodiment, the inner diameter of the cooling pipe 13 is changed between the large diameter pipe section and the small diameter pipe section along the moving direction for each of the moving zones Z 1 to Z 3. Repeatedly, adiabatic expansion and compression of compressed air are performed alternately to cool or cool and cool the compressed air alternately, and the distribution of water vapor in the compressed air is adjusted finely and the large-diameter pipe and small diameter Decrease or increase the moving speed of the compressed air moving through the pipe part, slowly move the steam in the crude state in the cooled compressed air, and quickly move the steam in the dense state in the warmed compressed air Combined with the stirring effect of the coiled cooling pipe 13, the distribution of water vapor in the compressed air is made uniform and stabilized, and this is sent to the gas-liquid separator 29.

すなわち、冷却槽４の上段の移動域Ｚ1の冷却管１３の内径Ｄ1を空気導入管２の内径よりも増径し、中段の移動域Ｚ2の冷却管１３の内径Ｄ2を空気導入管２と同径に形成し、下段の移動域Ｚ3の冷却管１３の内径Ｄ2を上段の移動域Ｚ1の内径Ｄ1と同径に形成し、直管部１３ｂの下半分を移動域Ｚ2の内径Ｄ3と同径に形成し、直管部１３ｂの上半分を移動域Ｚ1の内径Ｄ1と同径に形成し、大管部と細管部を交互に形成している。
そして、移動域Ｚ1で圧縮空気を断熱膨張させて冷却ないし降温し、水蒸気を拡散させて粗状態に分布させ、その流速を空気導入管２よりも減速させ、移動域Ｚ2で圧縮空気を断熱圧縮させて加温し、水蒸気を密集させて分布させ、その流速を増速して圧縮空気中の水蒸気の分布を均一化させる。 That is, the inner diameter D 1 of the cooling pipe 13 in the upper moving zone Z 1 of the cooling tank 4 is increased from the inner diameter of the air introducing pipe 2, and the inner diameter D 2 of the cooling pipe 13 in the middle moving zone Z 2 is set to the air introducing pipe. 2, the inner diameter D 2 of the cooling pipe 13 in the lower moving area Z 3 is formed to be the same diameter as the inner diameter D 1 of the upper moving area Z 1 , and the lower half of the straight pipe portion 13 b is in the moving area. Z 2 is formed to have the same diameter as the inner diameter D 3 , the upper half of the straight pipe portion 13 b is formed to have the same diameter as the inner diameter D 1 of the moving zone Z 1 , and the large pipe portion and the thin pipe portion are alternately formed.
Then, the compressed air is adiabatically expanded in the moving zone Z 1 to cool or cool, diffuse water vapor and distribute it in a rough state, decelerate the flow velocity from the air introduction pipe 2 , and compress the compressed air in the moving zone Z 2. Heating is performed by adiabatic compression, water vapor is concentrated and distributed, and the flow rate is increased to make the water vapor distribution in the compressed air uniform.

この後、移動域Ｚ3で圧縮空気を断熱膨張させて冷却ないし降温し、水蒸気を拡散させて粗状態に分布させ、その流速を移動域Ｚ2よりも減速させ、直管部１３ｂの下半部では圧縮空気を断熱圧縮させて加温し、水蒸気を密集させて分布しその流速を移動域Ｚ3よりも増速して、圧縮空気中の水蒸気の分布を均一化させ、直管部１３ｂの上半部で圧縮空気を断熱膨張させて冷却ないし降温し、水蒸気を拡散させて粗状態に分布させ、その流速を前記下半部よりも減速させて、水蒸気の分布を拡散させて流速を減速させ、圧縮空気中の水蒸気の分布を均一化させる。 Thereafter, the compressed air is adiabatically expanded in the moving zone Z 3 to cool or cool down, and the water vapor is diffused and distributed in a rough state, the flow velocity is decelerated from the moving zone Z 2 , and the lower half of the straight pipe portion 13b. In the section, the compressed air is adiabatically compressed and heated, the water vapor is concentrated and distributed, and the flow velocity is increased more than the moving zone Z 3 , and the distribution of the water vapor in the compressed air is made uniform, and the straight pipe section 13b. Compressed air is adiabatically expanded and cooled or cooled in the upper half of the water, and the water vapor is diffused and distributed in a rough state.The flow rate is reduced more slowly than the lower half, and the distribution of water vapor is diffused to increase the flow rate. Decelerate to make the distribution of water vapor in the compressed air uniform.

このようにこの実施形態は、圧縮空気中の水蒸気の拡散と密集を交互に繰り返し、その移動速度を加減速して水蒸気の分布の均一化を図り、一様に除湿ないし冷却し安定した圧縮空気を気液分離器２９へ送り出し、気液分離器２９の気液分離作用を安定かつ能率良く行なうようにしている。
この場合、冷却槽４のコイル状部１３ａを省略してエアーチャンバ５５を増設することも可能で、そのようにすることで構成を簡潔にし、冷却能力を向上することができる。 As described above, in this embodiment, the diffusion and concentration of water vapor in the compressed air are alternately repeated, the moving speed is accelerated and decelerated, the water vapor distribution is made uniform, and the compressed air is stably dehumidified or cooled. Is sent out to the gas-liquid separator 29 so that the gas-liquid separation action of the gas-liquid separator 29 is performed stably and efficiently.
