Description

本発明は、複数の凝縮ユニットを連結し、構成を簡潔化し部品点数を低減して小形軽量化と製作の容易化並びに低廉化を図るとともに、凝縮ユニットによる凝縮作用と断熱膨張作用を向上し得るようにした、圧縮空気の凝縮装置に関する。 INDUSTRIAL APPLICABILITY The present invention connects a plurality of condensing units, simplifies the configuration, reduces the number of parts, reduces the size and weight, facilitates manufacture, and lowers the cost. It relates to a condensing device for compressed air.

エアーコンプレッサから吐出された圧縮空気には凝縮水や油分が混在し、この圧縮空気をエアードライバーやインパクトレンチ等のエアーツールへ供給すると、空気導管の内部が錆び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、圧縮空気の供給管路にエアードライヤを取付けて水分を除去し、除湿・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。 Compressed air discharged from an air compressor contains condensed water and oil, and if this compressed air is supplied to an air tool such as an air driver or impact wrench, the inside of the air conduit will rust and the components inside the air tool will rust. Therefore, an air dryer is attached to the compressed air supply line to remove moisture, and dehumidified and dried compressed air is supplied to the air tool.

例えば、中空円筒体の上部に上カバーを取付け、また前記中空円筒体の内部に中空円筒状の仕切り管を取付け、該仕切り管の内側に略円錐状の複数の仕切り構造を上下に積み重ね、これを長尺のボルトを介してエアー案内子に連結するとともに、各仕切り構造内の上部に凹み空間と透孔を形成し、上カバーから中空円筒体内に圧縮空気を導入し、これを下方の仕切り構造から上方の仕切り構造へ移動し、透孔から上部の凹み空間へ噴出して、圧縮空気を断熱膨張し水分を除去するようにしたものがある（例えば、特許文献１参照）。 For example, an upper cover is attached to the upper part of the hollow cylindrical body, a hollow cylindrical partition pipe is attached inside the hollow cylindrical body, and a plurality of substantially conical partition structures are vertically stacked inside the partition pipe. is connected to the air guide via a long bolt, and a recessed space and a through hole are formed in the upper part of each partition structure, and compressed air is introduced from the upper cover into the hollow cylindrical body, which is used as the lower partition There is one that moves from the structure to an upper partition structure, ejects from a through hole into an upper recessed space, adiabatically expands compressed air, and removes moisture (see, for example, Patent Document 1).

しかし、前記装置は中空円筒体の内側に仕切管を配置し、この仕切管内に複数の異形の仕切り構造を積み重ねて配置し、各仕切り構造に小孔状の透孔を形成しているため、部品点数が多く、また仕切り構造に凹み空間と小孔状の透孔の形成を要して製作が複雑で難しく、更に中空円筒体に圧縮空気を導入後、仕切管内や仕切り構造内に移動させているため、中空円筒体や仕切管が大径になって大形化し、しかも仕切り構造を通しボルトで固定しているため、仕切り構造の数が通しボルトの長さで制約され、圧縮空気の凝縮能力が制限されて水分を充分に除去することができないという問題があった。 However, in the above device, a partition tube is arranged inside the hollow cylindrical body, a plurality of odd-shaped partition structures are stacked inside the partition tube, and a small through hole is formed in each partition structure. The number of parts is large, and it is complicated and difficult to manufacture because it requires the formation of recessed spaces and small through holes in the partition structure. As a result, the diameter of the hollow cylinder and the partition pipe become large, and the partition structure is fixed with through-bolts. There was a problem that the condensing capacity was limited and the moisture could not be sufficiently removed.

このような問題を解決するものとして、圧縮空気の供給管路に介挿した気液分離装置に、蓋体に連結した筒状容器を設け、該筒状容器内に筒状仕切り体と、該仕切り体内に配置した胴体部を設け、該胴体部の周面に複数の鍔部を設けるとともに、その一の鍔部に負圧用中空室に連通する気体流量制御小孔部を設け、胴体部に導入した圧縮空気を前記制御小孔部から負圧用中空室へ移動させて気液分離させるようにしたものがある（例えば、特許文献２参照）。 In order to solve such a problem, a gas-liquid separation device inserted in a compressed air supply line is provided with a cylindrical container connected to a lid, and a cylindrical partition and a cylindrical partition are provided in the cylindrical container. A body is provided inside the partition, a plurality of flanges are provided on the peripheral surface of the body, and one of the flanges is provided with a gas flow rate control small hole communicating with the negative pressure hollow chamber, There is a device in which introduced compressed air is moved from the small control hole to a negative pressure hollow chamber to separate gas and liquid (see, for example, Patent Document 2).

しかし、前記気液分離装置は構造が複雑で製作が難しく、しかも単一または複数の制御小孔部では気液の分離能率が低く、圧縮空気を十分に除湿し乾燥させることができなかった。 However, the gas-liquid separation device has a complicated structure and is difficult to manufacture, and the gas-liquid separation efficiency is low with a single or a plurality of control holes, and it is not possible to sufficiently dehumidify and dry the compressed air.

そこで、出願人は、圧縮空気の移動路に一または複数の凝縮ユニットを配置し、該凝縮ユニットは内部に圧縮空気を衝突させる衝突板と、圧縮空気を噴出させる狭小通路と、凝縮管内に噴出した圧縮空気を閉塞した圧縮通路に押し込み、押し戻された圧縮空気を衝突板の他側面に衝突させ、前記衝突板と狭小通路と圧縮通路と衝突板の他側面とで圧縮空気を繰り返し凝縮し断熱膨張させ、気液分離後、出口管へ移動して隣接する下流側の凝縮ユニットへ導入し、圧縮空気を能率良く除湿し乾燥させるようにした圧縮空気の凝縮装置を開発し、これを既に提案している（例えば、特許文献３参照）。 Therefore, the applicant has arranged one or more condensing units in the compressed air movement path, and the condensing unit has an impingement plate for colliding the compressed air inside, a narrow passage for ejecting the compressed air, and a condensing pipe. The compressed air is pushed into the closed compression passage, and the pushed back compressed air collides with the other side of the impingement plate, and the compressed air is repeatedly condensed on the impingement plate, the narrow passage, the compression passage, and the other side of the impingement plate to insulate. We developed a compressed air condensing device that efficiently dehumidifies and dries compressed air by expanding it, separating it from gas and liquid, moving it to an outlet pipe, introducing it into an adjacent downstream condensing unit, and already proposed this. (See Patent Document 3, for example).

しかし、この既に提案した圧縮空気の凝縮装置は、圧縮空気の導入時に衝突板に衝突させた後、その外周の環状通路に移動させて凝縮管内に噴出していたため、衝突による圧縮空気の凝縮に十分な効果を得られず、しかも押し戻された圧縮空気を衝突板の他側面に衝突させる際の圧縮空気の凝縮も所期の効果を得られず、十分な気液分離効果を得られないという問題があった。 However, in this already proposed condensing device for compressed air, when the compressed air is introduced, it collides with the impingement plate, moves to the annular passage on the outer circumference, and jets out into the condensing pipe. It is said that a sufficient effect cannot be obtained, and the desired effect cannot be obtained from the condensation of the compressed air when the pushed back compressed air collides with the other side surface of the impingement plate, and a sufficient gas-liquid separation effect cannot be obtained. I had a problem.

この問題を解決するため、出願人は更に改良を重ね、凝縮管を構成する各凝縮ユニット内の上流側に多数の通気孔を形成した通気板と衝突板を近接して配置し、通気板に圧縮空気を衝突して凝縮させた後、多数の通気孔から噴出させて精密に断熱膨張させ、圧縮空気の除湿ないし乾燥効果を向上するようにした圧縮空気の凝縮装置を開発し、これを既に提案している。 In order to solve this problem, the applicant made further improvements by arranging a ventilation plate with a large number of ventilation holes and a collision plate close to each other on the upstream side of each condensation unit that constitutes the condensation tube. We have developed a compressed air condensing device that improves the dehumidification or drying effect of compressed air by colliding and condensing the compressed air, then ejecting it from a number of ventilation holes for precise adiabatic expansion. is suggesting.

しかし、この既に提案した圧縮空気の凝縮装置は、凝縮管と各凝縮ユニット内の構成が複雑な上に、通気板と衝突板の配置が複雑になって製作が難しく、高価になるという問題があった。 However, this already-proposed compressed air condensing device has the problem that the condensing pipes and the configuration inside each condensing unit are complicated, and the arrangement of the ventilation plates and the impingement plates is complicated, making it difficult to manufacture and expensive. there were.

以下、本発明を図示の第１の実施形態について説明すると、図１乃至図７において１は工場に設置したエアーコンプレッサで、生成した高温高圧の圧縮空気を空気導管３からジョイント４へ送り出し、その出口管４ａから凝縮管５へ送出可能にしている。 The first embodiment of the present invention will be described below. In FIGS. 1 to 7, reference numeral 1 denotes an air compressor installed in a factory. It is made possible to deliver from the outlet pipe 4 a to the condensation pipe 5 .

前記凝縮管５は、複数の凝縮ユニット６、実施形態では５個の凝縮ユニット６を垂直方向に連結して配置され、該凝縮ユニット６の縦断面は中空楕円体に形成され、これは一組の凝縮ハウジング７，８と、その長軸側の両側に連結した一組の連結管９，１０、とから構成されている。
前記凝縮ハウジング７，８は肉厚の例えばステンレス鋼板またはアルミニウム板等の金属板を略椀形に成形し、その大径側の開口縁を向き合わせて接合し、その接合部を例えばＴＩＧ溶接等で溶接して連結している。図中、６ａは開口縁の溶接部である。 The condensing pipe 5 is arranged by vertically connecting a plurality of condensing units 6, in this embodiment, five condensing units 6, and the longitudinal section of the condensing units 6 is formed into a hollow ellipsoid, which is a set of and a pair of connecting tubes 9, 10 connected to both longitudinal sides thereof.
The condensation housings 7 and 8 are formed by forming a thick metal plate such as a stainless steel plate or an aluminum plate into a substantially bowl shape, and joining the large-diameter side opening edges thereof to face each other and joining the joints by TIG welding or the like. are welded and connected. In the figure, 6a is a welded portion at the edge of the opening.

前記凝縮ハウジング７，８の椀底部に大小異径の連結孔１１，１２が形成され、大径側の連結孔１１に連結管９の一端が挿入され、小径側の連結孔１２に連結管１０の一端が挿入され、それらの挿入部の内外位置が例えばＴＩＧ溶接等で溶接されている。図中、９ａ，９ｂおよび１０ａ，１０ｂはそれらの内外位置の溶接部である。 Connecting holes 11 and 12 having different diameters are formed in the bowl bottoms of the condensation housings 7 and 8. One end of a connecting pipe 9 is inserted into the connecting hole 11 on the large diameter side, and a connecting pipe 10 is inserted into the connecting hole 12 on the small diameter side. are inserted, and the inner and outer positions of the insertion portions are welded by, for example, TIG welding. In the figure, 9a, 9b and 10a, 10b are welds at their inner and outer positions.

前記連結管９，１０は大小異径の例えばステンレス鋼管またはアルミニウム管等の金属管を所定長さに切断し、このうち連結管９の長さを連結管１０よりも若干短く形成している。
前記連結管９の内面に雌ネジ部１３が形成され、最上位置の凝縮ユニット６に接続した連結管９の雌ネジ部１３に、ジョイント４の出口管４ａが螺着されている。
前記連結管１０の先端部外周にテーパネジ部１４が形成され、該テーパネジ部１４を直下位置の凝縮ユニット６に接続した連結管９の雌ネジ部１３に螺着している。 The connecting pipes 9 and 10 are formed by cutting metal pipes having different diameters, such as stainless steel pipes or aluminum pipes, into predetermined lengths.
A female threaded portion 13 is formed on the inner surface of the connecting pipe 9, and the outlet pipe 4a of the joint 4 is screwed into the female threaded portion 13 of the connecting pipe 9 connected to the condensing unit 6 at the uppermost position.
A tapered threaded portion 14 is formed on the outer circumference of the distal end portion of the connecting pipe 10, and the tapered threaded portion 14 is screwed into the female threaded portion 13 of the connecting pipe 9 connected to the condensing unit 6 directly below.

前記凝縮ハウジング７，８の開口側に一対の衝突板１５，１６が対向して配置され、該衝突板１５，１６に多数の同径の通気孔１７，１８が環状に配置されている。
前記衝突板１５，１６は肉厚の例えばステンレス鋼板またはアルミニウム板等の金属板によって同径の円板形に形成され、その外周部を凝縮ハウジング７，８の内面に例えばＴＩＧ溶接等で溶接して固定している。１５ａ，１６ａはその溶接部である。 A pair of impingement plates 15 and 16 are arranged facing each other on the opening sides of the condensation housings 7 and 8, and a large number of vent holes 17 and 18 of the same diameter are arranged in the impingement plates 15 and 16 in an annular shape.
The impingement plates 15 and 16 are made of a thick metal plate such as a stainless steel plate or an aluminum plate and are formed in the shape of discs having the same diameter. fixed. 15a and 16a are the welded portions.

この場合、通気孔１７，１８を対向して衝突板１５，１６を配置する代わりに、何れか一方の衝突板１５，１６を一定角度回動して配置し、通気孔１７，１８の取付け位置（位相）をずらせて配置し、例えば衝突板１５の通気孔１７から噴出した圧縮空気を衝突板１６の通気孔１８，１８の間に衝突させて、圧縮空気の衝突確度とその凝縮効果を向上させることが望ましい。 In this case, instead of arranging the collision plates 15 and 16 with the ventilation holes 17 and 18 facing each other, one of the collision plates 15 and 16 is rotated by a certain angle, and the mounting position of the ventilation holes 17 and 18 is changed. For example, the compressed air ejected from the air hole 17 of the collision plate 15 collides between the air holes 18, 18 of the collision plate 16 to improve the collision accuracy of the compressed air and its condensation effect. It is desirable to

その際、各凝縮ユニット６内の上側の連結管９に導入された圧縮空気は、凝縮ハウジング７内の凹状曲面に導かれて内部へ移動し、移動方向正面に配置した衝突板１５に衝突して凝縮され、その一部が液化するとともに、この前後に通気孔１７に押し込まれて通気板１５の他側面に噴出し、断熱膨張して一部を液化するようにされている。
この場合、液化された液摘は、圧縮空気に交じって吹き飛ばされ、下方へ移動するようにしている。 At that time, the compressed air introduced into the upper connecting pipe 9 in each condensation unit 6 moves inside by being guided by the concave curved surface in the condensation housing 7, and collides with the impact plate 15 arranged in front in the movement direction. It is condensed and partly liquefied, and is pushed into the ventilation hole 17 before and after this, is ejected to the other side of the ventilation plate 15, and adiabatically expands to partly liquefy.
In this case, the liquefied liquid is blown away by the compressed air and moves downward.

そして、通気板１５の他側面に噴出した圧縮空気は、相対する通気板１６に衝突して凝縮され、その一部が液化するとともに、この前後に通気孔１８に押し込まれて通気板１６の他側面に噴出し、断熱膨張して一部が液化するようにされている。その際、液化された液摘は、圧縮空気に交じって吹き飛ばされ、下方へ移動するようにしている。 The compressed air jetted to the other side of the ventilation plate 15 collides with the opposing ventilation plate 16 and is condensed. It blows out to the side, expands adiabatically, and partially liquefies. At that time, the liquefied liquid is blown away by the compressed air and moves downward.

こうして、通気孔１８から噴出された圧縮空気は、凝縮ハウジング８内の凹状曲面に導かれて連結管１０へ送り出され、直下の凝縮ユニット６内へ導入可能にされている。
この場合、連結管１０のテーパネジ部１４は、直下の凝縮ユニット６に接続した連結管９の雌ネジ部１３にねじ込まれているから、連結管９，１０の管径の差が縮小され、それらの内側を移動する圧縮空気の変動を抑制し、圧力損失を抑制して安定した移動を図るようにしている。 In this way, the compressed air ejected from the ventilation hole 18 is guided by the concave curved surface in the condensation housing 8, sent to the connecting pipe 10, and can be introduced into the condensation unit 6 immediately below.
In this case, since the tapered threaded portion 14 of the connecting pipe 10 is screwed into the female threaded portion 13 of the connecting pipe 9 connected to the condensation unit 6 immediately below, the difference in pipe diameter between the connecting pipes 9 and 10 is reduced. It suppresses the fluctuation of the compressed air moving inside the , and suppresses the pressure loss to achieve stable movement.

前記凝縮管５の外側に大径かつ長尺の冷却管を兼ねる保護筒１９が立設され、その下端部に支持筒２０が取付けられ、その下端のフランジ２０ａを不動の基板２１に固定している。
前記保護筒１９は、複数の凝縮ユニット６を収容可能な長さ約８０ｃｍ、内径約１０ｃｍの例えばステンレス鋼管またはアルミニウム管等の金属管で構成され、その下部を支持筒２０で堅固に支持し、その上端部をジョイント４の直下に開口して配置している。 A large-diameter and long protective tube 19 serving as a cooling tube is erected outside the condenser tube 5, and a support tube 20 is attached to the lower end thereof. there is
The protection cylinder 19 is composed of a metal tube such as a stainless steel tube or an aluminum tube having a length of about 80 cm and an inner diameter of about 10 cm that can accommodate a plurality of condensation units 6, and its lower part is firmly supported by a support cylinder 20, Its upper end is opened directly below the joint 4 .

前記基板２１の中央に大径の空気取入孔２２が形成され、該空気取入孔２２は基板２１の下部周辺の空気と連通可能にされ、この空気を保護筒１９のいわゆる煙突効果によって基板２１の下方から取り入れ、これを保護筒１９内に導入して上動させ、内側に配置した凝縮管５を冷却可能にしている。 A large-diameter air intake hole 22 is formed in the center of the substrate 21, and the air intake hole 22 can communicate with the air around the lower part of the substrate 21, and this air passes through the substrate by the so-called chimney effect of the protective cylinder 19. 21, introduced into the protective cylinder 19 and moved upward to cool the condensing tube 5 disposed inside.

前記凝縮管５の最下位置の凝縮ユニット６の連結管１０は、空気取入孔２２内の直上に配置され、該連結管１０のテーパネジ部１４を空気導管２３の上端部に螺着している。そして、空気導管２３を空気取入孔２２の下方に配管し、その適所を工場で使用するエアードライバー、インパクトレンチ等のエアーツール２４の供給管（図示略）に接続している The connecting pipe 10 of the condensing unit 6 at the lowest position of the condensing pipe 5 is arranged directly above the air intake hole 22, and the tapered threaded portion 14 of the connecting pipe 10 is screwed to the upper end of the air conduit 23. there is An air conduit 23 is laid below the air intake hole 22 and connected to a supply pipe (not shown) for an air tool 24 such as an air driver or an impact wrench used in the factory.

このように構成した圧縮空気の凝縮装置は、凝縮管５と保護筒１９の製作とそれらの組み立てを要する。このうち、凝縮管５の製作は、除湿ないし乾燥する圧縮空気の流量に応じて、１または複数の凝縮ユニット６の製作を要する。 A condensing device for compressed air constructed in this manner requires the manufacture and assembly of the condensing pipe 5 and the protective cylinder 19 . Among these, the production of the condensation pipe 5 requires the production of one or a plurality of condensation units 6 according to the flow rate of the compressed air to be dehumidified or dried.

前記凝縮ユニット６は、１組の凝縮ハウジング７，８を備え、これは肉厚（実施形態では３ｍｍ）のステンレス鋼板を、例えばプレス加工またはへら絞り加工によって略椀形に成形し、その椀底部に大小異径の連結孔１１，１２を形成する。 Said condensing unit 6 comprises a pair of condensing housings 7, 8, which are formed from a thick (3 mm in the embodiment) stainless steel plate into a generally bowl shape, for example by pressing or spinning, the bottom of which is , connecting holes 11 and 12 having different diameters are formed.

このように凝縮ユニット６の中間部の縦断面を略中空楕円体に形成することで、直管状の凝縮ユニット６に比べ管内断面積を拡径し、内部に配置する衝突板１５，１６の面積増と通気孔１７，１８の数量増を図って、圧縮空気の衝突効果と通気孔の噴出による断熱膨張効果を向上し、圧縮空気の除湿ないし乾燥を促進し得る。また、外側の表面積の増加を図って、保護筒１９内における凝縮ユニット６の空気との接触増を図って冷却を促し、凝縮管５による圧縮空気の除湿ないし乾燥を増進するようにしている。 By forming the vertical cross-section of the intermediate portion of the condensation unit 6 into a substantially hollow ellipsoid in this way, the internal cross-sectional area of the tube is enlarged compared to the straight-tube-shaped condensation unit 6, and the area of the impingement plates 15 and 16 disposed inside is increased. By increasing the number of ventilation holes 17 and 18, the impact effect of the compressed air and the adiabatic expansion effect due to the ejection of the ventilation holes can be improved, and the dehumidification or drying of the compressed air can be promoted. Further, by increasing the outer surface area, the contact between the condenser unit 6 and the air inside the protective tube 19 is increased to promote cooling, and the dehumidification or drying of the compressed air by the condenser tube 5 is promoted.

一方、連結管９，１０は大小異径の例えばステンレス鋼管またはアルミニウム管等の金属管を所定長さに切断し、連結管９の長さを連結管１０よりも若干短く形成し、連結管９の内面に雌ネジ部１３を形成し、連結管１０の先端部の外周にテーパネジ部１４を形成する。 On the other hand, the connecting pipes 9 and 10 are formed by cutting metal pipes having different diameters, such as stainless steel pipes or aluminum pipes, into predetermined lengths, forming the length of the connecting pipe 9 slightly shorter than that of the connecting pipe 10. A female screw portion 13 is formed on the inner surface of the connecting pipe 10 , and a taper screw portion 14 is formed on the outer circumference of the distal end portion of the connecting pipe 10 .

また、凝縮ユニット６内に配置する衝突板１５，１６は、肉厚（実施形態では３ｍｍ）の例えばステンレス鋼板またはアルミニウム板等の金属板を、例えばプレス加工によって同径の円板状に打ち抜き、その板面に複数の通気孔１７，１８を環状に配置する。
そして、凝縮ハウジング７，８の大径の開口側の内面に、通気孔１７，１８を形成した衝突板１５，１６を配置し、その接合部周面を例えばＴＩＧ溶接等で溶接１５ａ，１６ａする。 The impingement plates 15 and 16 arranged in the condensation unit 6 are formed by punching a metal plate such as a stainless steel plate or an aluminum plate having a thickness (3 mm in the embodiment) into a disk shape of the same diameter by, for example, pressing. A plurality of ventilation holes 17 and 18 are arranged in a ring on the plate surface.
Collision plates 15 and 16 having ventilation holes 17 and 18 are placed on the inner surfaces of the large-diameter openings of the condensation housings 7 and 8, and the peripheral surfaces of the joints are welded 15a and 16a by TIG welding or the like. .

この後、凝縮ハウジング７の連結孔１１に連結管９の一端を挿入し、その接合部の内外位置を例えばＴＩＧ溶接等で溶接９ａ，９ｂして連結する。
また、凝縮ハウジング８の連結孔１２に連結管１０の一端を挿入し、その接合部の内外位置を例えばＴＩＧ溶接等で溶接１０ａ，１０ｂして連結する。 After that, one end of the connecting pipe 9 is inserted into the connecting hole 11 of the condensation housing 7, and the inner and outer positions of the joint are welded 9a, 9b by TIG welding or the like.
Also, one end of the connecting pipe 10 is inserted into the connecting hole 12 of the condensation housing 8, and the inner and outer positions of the joint are welded 10a, 10b by TIG welding or the like.

こうして、衝突板１５を溶接し、連結管９を連結した凝縮ハウジング７の大径側の開口端部と、衝突板１６を溶接し、連結管１０を連結した凝縮ハウジング８の大径側の開口端部とを向き合わせて接合し、その接合部を例えばＴＩＧ溶接等で溶接６ａして連結する。
このようにして一の凝縮ユニット６を製作後、別の凝縮ユニット６を同様な要領で製作し、複数の凝縮ユニット６を製作する。 Thus, the collision plate 15 is welded to the large-diameter side opening of the condensation housing 7 to which the connection pipe 9 is connected, and the collision plate 16 is welded to the large-diameter side opening of the condensation housing 8 to which the connection pipe 10 is connected. The ends are joined face to face, and the joints are joined by welding 6a by TIG welding or the like, for example.
After manufacturing one condensing unit 6 in this way, another condensing unit 6 is manufactured in a similar manner, and a plurality of condensing units 6 are manufactured.

次に、前記製作した凝縮ユニット６を除湿ないし乾燥する圧縮空気の流量に応じて所要個数用意し、これらを組み立てる。この組み立てに際しては、各凝縮ユニット６の連結管９と連結管１０を同様に配置し、例えば連結管９を一側に配置し、連結管１０を他側に配置する。 Next, a required number of the condensing units 6 manufactured as described above are prepared according to the flow rate of compressed air for dehumidification or drying, and these are assembled. When assembling, the connecting pipes 9 and 10 of each condensation unit 6 are arranged in the same manner, for example, the connecting pipe 9 is arranged on one side and the connecting pipe 10 is arranged on the other side.

そして、連結管１０のテーパネジ部１４を隣接する下流側の凝縮ユニット６の連結管９の雌ネジ部１３にねじ込み、この二つの凝縮ユニット６，６を連結する。
同様な要領で、凝縮ユニット６の連結管１０のテーパネジ部１４を、隣接する下流側の凝縮ユニット６の連結管９の雌ネジ部１３にねじ込んで、凝縮ユニット６を次々に連結する。
実施形態では、５個の凝縮ユニット６を連結したところで、凝縮管５の組み立てを完了する。 Then, the tapered threaded portion 14 of the connecting pipe 10 is screwed into the female threaded portion 13 of the connecting pipe 9 of the condensing unit 6 on the adjacent downstream side to connect the two condensing units 6 , 6 .
In a similar manner, the tapered threaded portion 14 of the connecting pipe 10 of the condensing unit 6 is screwed into the female threaded portion 13 of the connecting pipe 9 of the adjacent downstream condensing unit 6 to connect the condensing units 6 one after another.
In the embodiment, the assembly of the condensation tube 5 is completed when the five condensation units 6 are connected.

このように本発明の凝縮装置は、凝縮ハウジング７，８の成形と連結孔１１，１２の形成、連結管９，１０の所定長の切断とネジ部１３，１４の形成、衝突板１５，１６の打ち抜きと通気孔１７，１８の形成、およびそれらの溶接による組み立てによって行なえ、従来のような衝突板の製作と取付け、複雑な仕切壁の成形と出口管との組み立てを要しないから、部品点数が少なく凝縮ユニット６内の構造が簡単で、その製作や組み立てを容易に行なえ、これを安価に製作し得る。 As described above, the condensing device of the present invention is formed by molding the condensing housings 7 and 8, forming the connecting holes 11 and 12, cutting the connecting pipes 9 and 10 to predetermined lengths, forming the screw portions 13 and 14, and forming the impingement plates 15 and 16. , forming the ventilation holes 17 and 18, and assembling them by welding. The condensing unit 6 has a simple structure and can be easily manufactured and assembled at a low cost.

こうして凝縮管５を組み立て後、所定長さの直管状の保護筒１９を用意し、該保護筒１９をジョイント４の直下に立設する。その際、保護筒１９の下端部に支持筒２０を取付け、支持筒２０の下端のフランジ２０ａを不動の基板２１に固定して、保護筒１９を支持する。
次に、基板２１の空気取入孔２２から凝縮管５を挿入し、これを上方へ移動して凝縮管５の最上位置の凝縮ユニット６に接続した連結管９の雌ネジ部１３を、ジョイント４の出口管４ａにねじ込んで連結する。 After assembling the condenser tube 5 in this manner, a straight pipe-shaped protective cylinder 19 having a predetermined length is prepared and erected immediately below the joint 4 . At that time, the support tube 20 is attached to the lower end of the protective tube 19, and the flange 20a at the lower end of the support tube 20 is fixed to the stationary substrate 21 to support the protective tube 19. As shown in FIG.
Next, the condenser tube 5 is inserted from the air intake hole 22 of the substrate 21, moved upward, and the female threaded portion 13 of the connecting tube 9 connected to the condensation unit 6 at the uppermost position of the condenser tube 5 is connected to the joint. 4 is screwed into the outlet pipe 4a and connected.

一方、空気取入孔２２の直上に位置する凝縮管５の最下位置、つまり下流側の凝縮ユニット６の連結管１０のテーパネジ部１４に、空気導管２３の上端部をねじ込んで連結する
そして、空気導管２３の下方、つまり下流部の適所に各種のエアーツール２４に対する空気供給管（図示略）を接続する。 On the other hand, the upper end of the air conduit 23 is screwed into the tapered threaded portion 14 of the connecting pipe 10 of the condensation unit 6 on the lowermost position of the condensation pipe 5 located directly above the air intake hole 22, that is, the downstream condensation unit 6. An air supply pipe (not shown) for various air tools 24 is connected to an appropriate location below the air conduit 23, ie, downstream.

この場合、凝縮管５や保護筒１９は、共に長さが約８０ｃｍで比較的コンパクトで大重量ではないから、それらの組み立てや据え付けを容易に行える。
しかも、凝縮管５と保護筒１９を垂直に配置しているから、その設置面積がコンパクトになり、工場の屋内外での設置に好適である。 In this case, the condensation tube 5 and the protective tube 19 are both about 80 cm long, relatively compact, and not heavy, so that they can be easily assembled and installed.
Moreover, since the condenser pipe 5 and the protective cylinder 19 are arranged vertically, the installation area is compact, which is suitable for installation inside and outside the factory.

こうして設置した本発明の凝縮装置は、保護筒１９の内側に凝縮管５を配置しているから、凝縮装置を屋外に設置した際に凝縮管５を風雨や日射から防護し得る。
このような凝縮装置において、エアーコンプレッサ１を駆動して生成した圧縮空気を、空気導管３からジョイント４を介して、出口管４ａから凝縮管５の上端部の連結管９へ導入する。 In the condensing device of the present invention installed in this manner, the condensing pipes 5 are arranged inside the protective cylinder 19, so that the condensing pipes 5 can be protected from wind, rain and sunlight when the condensing device is installed outdoors.
In such a condensing device, compressed air generated by driving the air compressor 1 is introduced from the air conduit 3 through the joint 4 to the connecting pipe 9 at the upper end of the condensing pipe 5 from the outlet pipe 4a.

前記圧縮空気は凝縮管５の最上位置の凝縮ユニット６へ移動し、該ユニット６の凝縮ハウジング７の湾曲面に導かれて衝突板１５に衝突して凝縮し、その一部を液化して冷却された後、通気孔１７に押し込まれて衝突板１５の他側に噴出し、断熱膨張して一部を液化し冷却される。 The compressed air moves to the condensing unit 6 at the top of the condensing tube 5, is guided by the curved surface of the condensing housing 7 of the unit 6, collides with the impingement plate 15, is condensed, and is partially liquefied and cooled. After that, it is pushed into the ventilation hole 17 and ejected to the other side of the collision plate 15, adiabatically expanded, and partially liquefied and cooled.

この後、圧縮空気は相対する衝突板１６に衝突して凝縮し、その一部を液化して冷却された後、通気孔１８に押し込まれて通気板１６の他側に噴出し、断熱膨張して一部を液化され冷却される。
この場合、通気孔１７，１８を同軸上に対向して衝突板１５，１６を配置する代わりに、何れか一方の衝突板１５，１６を一定角度回動して配置し、通気孔１７，１８の取付け位置（位相）をずらせて配置すれば、例えば衝突板１５の通気孔１７から噴出した圧縮空気を衝突板１６の通気孔１８，１８の間に確実に衝突させ、圧縮空気の衝突ないし凝縮効果を向上させることができる。 After that, the compressed air collides with the opposing impingement plates 16 to condense, and after being partially liquefied and cooled, the compressed air is pushed into the ventilation holes 18 and ejected to the other side of the ventilation plates 16, where it adiabatically expands. partly liquefied and cooled.
In this case, instead of arranging the collision plates 15 and 16 so that the ventilation holes 17 and 18 are coaxially opposed to each other, one of the collision plates 15 and 16 is rotated by a certain angle, and the ventilation holes 17 and 18 are arranged. , the compressed air ejected from the air hole 17 of the impingement plate 15 is surely impinged between the air holes 18, 18 of the impingement plate 16, and the compressed air collides or condenses. You can improve the effect.

この後、圧縮空気は凝縮ハウジング８の湾曲面に導かれて連結管１０へ移動し、該連結管１０に接続した連結管９を介して、隣接する下流側の凝縮ユニット６へ移動する。
圧縮空気は前述と同様に、凝縮ハウジング７の湾曲面に導かれて凝縮ユニット６へ移動し、衝突板１５に衝突して凝縮し、その一部を液化して冷却された後、通気孔１７に押し込まれて衝突板１５の他側に噴出し、断熱膨張して一部を液化し冷却される。 After that, the compressed air is guided by the curved surface of the condensing housing 8, moves to the connecting pipe 10, passes through the connecting pipe 9 connected to the connecting pipe 10, and moves to the condensing unit 6 on the adjacent downstream side.
As described above, the compressed air is guided by the curved surface of the condensation housing 7, moves to the condensation unit 6, collides with the impingement plate 15, is condensed, and is partially liquefied and cooled. , and ejects to the other side of the collision plate 15, adiabatically expands, and is partially liquefied and cooled.

その後、圧縮空気は相対する衝突板１６に衝突して凝縮し、その一部を液化して冷却された後、通気孔１７に押し込まれて通気板１６の他側に噴出し、断熱膨張して一部を液化し冷却される。
そして、圧縮空気は凝縮ユニット６から連結管１０へ移動し、該連結管１０に接続した連結管９を介して、隣接する下流側の凝縮ユニット６へ移動する。 After that, the compressed air collides with the opposing impingement plates 16 and condenses, and after being partially liquefied and cooled, it is pushed into the ventilation holes 17 and ejected to the other side of the ventilation plate 16, where it adiabatically expands. A portion is liquefied and cooled.
Then, the compressed air moves from the condensing unit 6 to the connecting pipe 10 and moves to the adjacent downstream condensing unit 6 via the connecting pipe 9 connected to the connecting pipe 10 .

以後、圧縮空気は下流側の凝縮ユニット６へ順次移動し、各凝縮ユニット６で凝縮と断熱膨張作用を繰り返し受けて次第に除湿ないし乾燥され、冷却される。 After that, the compressed air is sequentially moved to the downstream condensation unit 6, and repeatedly subjected to condensation and adiabatic expansion in each condensation unit 6 to be gradually dehumidified or dried and cooled.

こうして凝縮管５の最下位置の凝縮ユニット６へ移動した圧縮空気は、十分に除湿ないし乾燥されて冷却され、凝縮ユニット６の連結管１０に接続した空気導管２３へ移動し、該空気導管２３の適所に接続した各エアーツール２４に連通する空気供給管（図示略）へ供給され、エアーツール２４の機能低下や故障を防止し得る。 The compressed air thus moved to the lowermost condensing unit 6 of the condensing pipe 5 is sufficiently dehumidified or dried and cooled, and moves to the air conduit 23 connected to the connecting pipe 10 of the condensing unit 6. is supplied to an air supply pipe (not shown) that communicates with each air tool 24 that is connected to a proper place of the air tool 24, thereby preventing functional deterioration and failure of the air tool 24.

一方、圧縮空気の凝縮管５ないし凝縮ユニット６への導入と前後して、保護筒１９のトンネル効果が機能し、空気が空気取入孔２２から保護筒１９内に取入れられ、これが上動して凝縮管５ないし凝縮ユニット６と連結管９，１０の表面に接触し、それらを冷却する
したがって、凝縮管５による圧縮空気の凝縮効果と断熱膨張効果が増進される。 On the other hand, before or after the compressed air is introduced into the condenser tube 5 or the condensation unit 6, the tunnel effect of the protective cylinder 19 functions, and air is taken into the protective cylinder 19 from the air intake hole 22, and this moves upward. The condensing pipe 5 or the condensing unit 6 and the surfaces of the connecting pipes 9 and 10 are brought into contact with each other to cool them.

こうして熱交換された空気は、保護筒１９の上端部から放出される。その際、凝縮ハウジング７，８は椀形に形成され、直管に比べて接触面積を広く確保しているから、それだけ冷却効果が促進され、圧縮空気の除湿ないし乾燥が促進される。 The air heat-exchanged in this manner is discharged from the upper end of the protective cylinder 19 . At this time, the condensing housings 7 and 8 are formed in a bowl shape and ensure a larger contact area than straight pipes, so the cooling effect is promoted accordingly, and the dehumidification or drying of the compressed air is promoted.

図８乃至図２６は本発明の他の実施形態を示し、前述の実施形態と対応する構成部分に同一の符号を用いている。このうち、図８および図９は本発明の第２の実施形態を示し、この実施形態は凝縮管５を垂直に立設する代わりに、水平方向から僅かに傾斜（θ）して配置し、保護筒１９も同軸方向に配置し、つまり水平方向から僅かに傾斜（θ）して配置し、凝縮管５の設置の容易化を図るとともに、保護筒１９の煙突効果を確保して、保護筒１９による凝縮管５の冷却効果を保持するようにしている。
この実施形態における凝縮管５と凝縮ユニット６、連結管８，９の製作や配置、取付け、並びにそれらの作用効果は、前述の実施形態と実質的に同一である。 8 to 26 show another embodiment of the present invention, and the same reference numerals are used for components corresponding to those of the previous embodiment. Among them, FIGS. 8 and 9 show a second embodiment of the present invention, in which the condensation tube 5 is arranged slightly inclined (θ) from the horizontal instead of standing vertically, The protective cylinder 19 is also arranged in the coaxial direction, that is, arranged with a slight inclination (θ) from the horizontal direction to facilitate the installation of the condenser tube 5 and secure the chimney effect of the protective cylinder 19. The cooling effect of the condenser tube 5 by 19 is maintained.
The production, arrangement, and attachment of the condensation pipe 5, the condensation unit 6, and the connecting pipes 8 and 9 in this embodiment, as well as their effects, are substantially the same as in the previous embodiment.

図１０は本発明の第３の実施形態を示し、この実施形態は凝縮ハウジング７，８の間に例えばステンレス鋼管またはアルミニウム管等の金属製の継手管２５を介挿し、それらの接合部を溶接するとともに、継手管２５の内側に複数の通気板２６～２９を等間隔に配置して溶接し、これらの通気板２６～２９に通気孔１７，１８と同径の複数の通気孔３０～３３に位相をずらせて環状に配置し、凝縮ユニット６を長尺に構成している。 FIG. 10 shows a third embodiment of the invention, in which a metal fitting 25, for example a stainless steel or aluminum tube, is inserted between the condensation housings 7, 8 and the joints welded together. In addition, a plurality of ventilation plates 26 to 29 are arranged at equal intervals inside the joint pipe 25 and welded, and a plurality of ventilation holes 30 to 33 having the same diameter as the ventilation holes 17 and 18 are formed in these ventilation plates 26 to 29. The condensing unit 6 is elongated by arranging it annularly with a phase shift.

このように構成することで、椀形の凝縮ハウジング７，８に単一の通気板１５，１６を取付ける構成に比べて、継手管２５に複数の通気板２６～２９を容易に取付けられ、凝縮ユニット６を合理的かつ安価に製作することができるとともに、圧縮空気を通気板２６～２９に効率良く衝突させ、その凝縮効果を向上するとともに、通気孔３０～３３からの噴出による断熱膨張効果を向上して圧縮空気の凝縮効果を促進し、除湿乾燥効果を向上するようにしている。 By constructing in this way, compared to the structure in which a single ventilation plate 15, 16 is attached to the bowl-shaped condensation housings 7, 8, the plurality of ventilation plates 26 to 29 can be easily attached to the joint tube 25, and condensation can be achieved. The unit 6 can be manufactured rationally and inexpensively, the compressed air can be efficiently collided with the ventilation plates 26 to 29 to improve the condensation effect, and the adiabatic expansion effect by blowing from the ventilation holes 30 to 33 can be improved. It improves the condensing effect of the compressed air and improves the dehumidifying and drying effect.

この実施形態における凝縮ユニット５４は、継手管３１～３３の内側に通気孔を形成した通気板を設ける代わりに、継手管３１～３３の内側に、該継手管３１～３３の外径の略１／２弱の長尺の通気管５５を配置し、その一端を連結管９の雌ネジ部１３に螺着して取付け、他端を凝縮ハウジング８の内側に配置し、その端部に衝突板５６を取付けて閉塞し、該衝突板５６に通気管９内に送り込まれた圧縮空気を衝突させて凝縮可能にしている。 FIG. 21 shows a sixth embodiment of the present invention, which differs from the condensing unit arranged inside the condensing device 35 of the fourth and fifth embodiments.
In the condensation unit 54 in this embodiment, instead of providing ventilation plates with ventilation holes formed inside the joint pipes 31 to 33, the inside of the joint pipes 31 to 33 is provided with an outer diameter of about 1 of the outer diameter of the joint pipes 31 to 33. A long vent pipe 55 of slightly less than /2 is arranged, one end of which is screwed into the female threaded portion 13 of the connecting pipe 9, the other end is arranged inside the condensation housing 8, and an impingement plate is attached to that end. 56 is attached and closed, and the compressed air sent into the vent pipe 9 collides against the impingement plate 56 so that it can be condensed.

前記通気管５５の外周面の複数個所に噴気部５７～５９を設け、該噴気部５７～５９に多数の通気孔６０を形成し、該通気孔６０から圧縮空気を通気管５５の外側へ噴出して断熱膨張可能にしている。
図中、６１，６２は通気管５０を継手管３１，３２に支持する通気可能な保持板である Blowing portions 57 to 59 are provided at a plurality of locations on the outer peripheral surface of the vent pipe 55, and a large number of vent holes 60 are formed in the blow portions 57 to 59, and compressed air is jetted out of the vent pipe 55 from the vent holes 60. It is insulated and inflatable.

その際、噴気部５７～５９を通気管５５の外周面の複数個所に限定して通気孔６０を形成しているから、通気孔６０からの圧縮空気の噴出速度を一定に保持させて、所期の断熱膨張効果を得られる。 In the condensation unit 54 of this embodiment, the vent pipe 55 is formed to have a smaller diameter than the joint pipes 31 to 33, and the compressed air introduced into the vent pipe 55 collides with the impingement plate 56 to be condensed. The compressed air is blown out and adiabatically expanded to improve the condensation effect of the compressed air and enhance the dehumidification effect. Therefore, the jet speed of the compressed air from the ventilation hole 60 can be kept constant, and the desired adiabatic expansion effect can be obtained.

こうして冷却され除湿された圧縮空気は、継手管３１～３３と通気管５５の間を移動し、連結管１０に送り出される。
したがって、この実施形態の凝縮ユニット５４を第４および第５の実施形態と同様に凝縮装置３５内に組み込めば、除湿ないし冷却効果が一層向上する。 The cooled and dehumidified compressed air moves between the joint pipes 31 to 33 and the ventilation pipe 55 and is sent to the connecting pipe 10 .
Therefore, if the condensing unit 54 of this embodiment is incorporated in the condensing device 35 as in the fourth and fifth embodiments, the dehumidifying or cooling effect is further improved.

図２２および図２３は前述した第６の実施形態の応用形態を示し、この応用形態は、通気管５５の噴気部５７～５９の下流側に衝突板６３を設け、該衝突板６３に複数の噴口６４を形成している。
そして、通気管５５内を移動する圧縮空気を各衝突板６３に衝突して凝縮可能にし、また各通気孔６０から圧縮空気を噴出して断熱膨張可能にしている。 22 and 23 show an application form of the sixth embodiment described above. In this application form, a collision plate 63 is provided on the downstream side of the blowing portions 57 to 59 of the vent pipe 55, and the collision plate 63 is provided with a plurality of Forms an injection port 64 .
Compressed air moving in the ventilation pipe 55 collides with each collision plate 63 to be condensed, and the compressed air is ejected from each ventilation hole 60 to be adiabatically expanded.

すなわち、この応用形態は第６の実施形態と同様に各衝突板に圧縮空気を衝突させて凝縮させる一方、圧縮空気を通気孔から噴出して断熱膨張させ、通気管５５の内外で圧縮空気の除湿と冷却を増進するようにしている。 That is, in this application mode, as in the sixth embodiment, the compressed air collides with the collision plates to be condensed, and the compressed air is jetted out from the ventilation holes to be adiabatically expanded. It is designed to increase dehumidification and cooling.

図２４乃至図２６は本発明の第７の実施形態を示している。この実施形態は、第３実施形態のように凝縮ハウジング７，８の間に例えばステンレス鋼管またはアルミニウム管等の金属製の単一の継手管２５を配置し、該継手管２５に通気孔３０～３３を形成した複数の通気板２６～２９をＴＩＧ溶接して取付ける代わりに、図２４および図２５のように、凝縮ハウジング７，８の間にアルミニウム管製の複数の継手管２５ａ～２５ｍを配置し、これらを各管端部に形成したフランジｆ1～ｆ13を向き合わせ、そのボルト孔またはビス孔（図示略）にボルト６３またはビスを挿入し、これにナット６４をねじ込んで緊締し連結している。 24 to 26 show a seventh embodiment of the invention. In this embodiment, a single joint pipe 25 made of metal such as a stainless steel pipe or an aluminum pipe is arranged between the condensation housings 7 and 8 as in the third embodiment, and the joint pipe 25 is provided with vent holes 30 to Instead of attaching a plurality of vent plates 26-29 forming 33 by TIG welding, a plurality of joint tubes 25a-25m made of aluminum tubing are arranged between the condensing housings 7, 8 as shown in FIGS. 24 and 25. Then, the flanges f 1 to f 13 formed at each pipe end face each other, a bolt 63 or a screw is inserted into the bolt hole or screw hole (not shown), and a nut 64 is screwed into it to tighten and connect. is doing.

前記継手管２５ａ～２５ｍは長さが短くコンパクトであり、その中間部に、通気孔３０～３３…を形成したアルミニウム板製の通気板２６～２９…を接着剤で接着６５して固定し、個々に通気板２６～２９を取付けた継手管２５ａ～２５ｍを個別に連結している。
通気板２６～２９は例えばアルミニウム板をプレス成形して打ち抜き、それらに通気孔３０～３３…をプレスで打ち抜き、通気板２６～２９の周面に接着剤を塗布して継手管２５ａ～２５ｍに接着６５している。 The joint pipes 25a to 25m are short and compact, and are fixed by bonding 65 with an adhesive 65 to ventilation plates 26 to 29 made of aluminum plates having ventilation holes 30 to 33 formed in their intermediate portions, The joint pipes 25a to 25m to which the ventilation plates 26 to 29 are individually attached are individually connected.
The ventilation plates 26 to 29 are formed by press-molding and punching, for example, an aluminum plate, punching out ventilation holes 30 to 33, etc., and applying an adhesive to the peripheral surfaces of the ventilation plates 26 to 29 to attach them to the joint pipes 25a to 25m. It is glued 65 .

前記継手管２５ａ～２５ｍはアルミニウム管で構成しているから、ステンレス鋼管に比べて軽量で安価であり、その製作も容易である。また、通気板２６～２９はアルミニウム板で構成しているから、ステンレス鋼板に比べて軽量で安価であり、その通気孔３０～３３の形成や継手管２５ａ～２５ｍへの取付けも、特殊溶接の代わりに簡単な接着６５によって行えるから、手間が少なく容易かつ安価に行える。 Since the joint pipes 25a to 25m are made of aluminum pipes, they are lighter and less expensive than stainless steel pipes, and are easy to manufacture. In addition, since the ventilation plates 26-29 are made of aluminum plates, they are lighter and less expensive than stainless steel plates. Instead, it can be done by simple adhesion 65, so that it can be done easily and inexpensively with less labor.

なお、前述の応用形態として、図２４のように各継手管２５ａ～２５ｍに単一の通気板を取付け、個々に継手管２５ａ～２５ｍを連結する代わりに、例えば図２６のように１の継手管に複数の継手管２５ａ～２５ｄを連結して継手管を構成すれば、継手管２５ａ～２５ｄの連結個数が低減し、フランジの形成を省略して構成が簡潔になり、またその連結の手間を節減して凝縮ユニット６を合理的に構成し、これを容易かつ安価に製作し得る。 As an application form described above, instead of attaching a single ventilation plate to each of the joint pipes 25a to 25m as shown in FIG. If a plurality of joint pipes 25a to 25d are connected to a pipe to form a joint pipe, the number of joint pipes 25a to 25d connected can be reduced, the formation of flanges can be omitted, and the structure can be simplified. can be rationally constructed and manufactured easily and inexpensively.

その際、各凝縮ユニット６内の上側の連結管９に導入された圧縮空気は、凝縮ハウジング７内の凹状曲面に導かれて内部へ移動し、移動方向正面に配置した衝突板１５に衝突して凝縮され、その一部が液化するとともに、この前後に通気孔１７に押し込まれて衝突板１５の他側面に噴出し、断熱膨張して一部を液化するようにされている。
この場合、液化された液摘は、圧縮空気に交じって吹き飛ばされ、下方へ移動するようにしている。 At that time, the compressed air introduced into the upper connecting pipe 9 in each condensation unit 6 moves inside by being guided by the concave curved surface in the condensation housing 7, and collides with the impact plate 15 arranged in front in the movement direction. It is condensed and partly liquefied, and is pushed into the ventilation hole 17 before and after this and is ejected to the other side surface of the impingement plate 15, adiabatically expands, and partly liquefied.
In this case, the liquefied liquid is blown away by the compressed air and moves downward.

It blows out to the side, expands adiabatically, and partially liquefies. At that time, the liquefied liquid is blown away by the compressed air and moves downward.

その後、圧縮空気は相対する衝突板１６に衝突して凝縮し、その一部を液化して冷却された後、通気孔１７に押し込まれて衝突板１６の他側に噴出し、断熱膨張して一部を液化し冷却される。
そして、圧縮空気は凝縮ユニット６から連結管１０へ移動し、該連結管１０に接続した連結管９を介して、隣接する下流側の凝縮ユニット６へ移動する。 After that, the compressed air collides with the opposing impingement plates 16 and condenses, and after being partially liquefied and cooled, it is pushed into the ventilation hole 17 and ejected to the other side of the impingement plate 16, where it adiabatically expands. A portion is liquefied and cooled.
Then, the compressed air moves from the condensing unit 6 to the connecting pipe 10 and moves to the adjacent downstream condensing unit 6 via the connecting pipe 9 connected to the connecting pipe 10 .

このように構成することで、椀形の凝縮ハウジング７，８に単一の衝突板１５，１６を取付ける構成に比べて、継手管２５に複数の通気板２６～２９を容易に取付けられ、凝縮ユニット６を合理的かつ安価に製作することができるとともに、圧縮空気を通気板２６～２９に効率良く衝突させ、その凝縮効果を向上するとともに、通気孔３０～３３からの噴出による断熱膨張効果を向上して圧縮空気の凝縮効果を促進し、除湿乾燥効果を向上するようにしている。 By constructing in this way, compared to the structure in which a single impingement plate 15, 16 is mounted on the bowl-shaped condensation housings 7, 8, the plurality of ventilation plates 26 to 29 can be easily mounted on the joint pipe 25, and condensation can be achieved. The unit 6 can be manufactured rationally and inexpensively, the compressed air can be efficiently collided with the ventilation plates 26 to 29 to improve the condensation effect, and the adiabatic expansion effect by blowing from the ventilation holes 30 to 33 can be improved. It improves the condensing effect of the compressed air and improves the dehumidifying and drying effect.
