Description

本発明は、空気増幅器を利用した圧縮空気噴射装置に関し、より詳細には、圧縮空気を供給する導管を２つの分岐管に分けてその分岐管の上部に空気増幅器を共に連結して空気増幅器で増幅された空気の圧力によって周辺装備の障害なく、より多量の周辺空気をより早い速度でバグフィルターに均一に供給して高い脱塵効果が発揮できるようにした空気増幅器を利用した圧縮空気噴射装置に関する。   The present invention relates to a compressed air injection apparatus using an air amplifier, and more specifically, a pipe for supplying compressed air is divided into two branch pipes, and an air amplifier is connected to the upper part of the branch pipe to form an air amplifier. Compressed air injection device using an air amplifier that can supply a large amount of ambient air uniformly to the bag filter at a faster speed without any obstacles to the surrounding equipment due to the amplified air pressure so that a high dust removal effect can be exhibited. About.

一般に、ほこりが多く発生する場所で室内空気中に含まれて浮遊するほこりを捕集して綺麗な空気に浄化させて外部に排出する浄化装置である集塵機にはバグフィルターを用いる。このようなバグフィルターは、空気を濾過して排出する方向とは対方である下側方向に圧縮空気を噴射してバグフィルターに捕集された汚染物を脱離させてバッグ(Ｂａｇ)の封止現象を防止している。   In general, a bag filter is used for a dust collector that is a purification device that collects floating dust contained in indoor air in a place where a lot of dust is generated, purifies it into clean air, and discharges it to the outside. Such a bag filter injects compressed air in a downward direction opposite to the direction in which air is filtered and discharged to desorb contaminants collected in the bag filter and The sealing phenomenon is prevented.

それによって、従来のバグフィルターに圧縮空気を噴射して汚染物を脱離させる圧縮空気噴射装置は、図５に示すように、噴射される空気の量と速度を増大させるために圧縮空気が供給される導管１０とバグフィルターを一定距離離隔させ、圧縮空気が供給される導管の下部には流体が湾曲面を流れる際に表面に吸着する傾向であるコアンダ効果を極大化させることができるインジェクター２０を結合して使用した。   As a result, a compressed air injection device that injects compressed air onto a conventional bag filter to desorb contaminants is supplied with compressed air to increase the amount and speed of the injected air, as shown in FIG. An injector 20 that can separate the conduit 10 and the bag filter that are spaced apart from each other by a certain distance and maximize the Coanda effect that tends to adsorb to the surface when fluid flows through the curved surface in the lower portion of the conduit to which compressed air is supplied. Used in combination.

しかし、このようにコアンダ効果を極大化するインジェクター２０を圧縮空気が供給される導管１０の下部に結合する場合には、理論上に圧縮空気の約８〜２０倍に当たる空気が周りからバグフィルターに流入されなければならないことにもかかわらず、インジェクター２０上部にある圧縮空気の導管１０が周辺空気の流れを妨げて実際には圧縮空気の約４〜８倍に当たる空気のみがバグフィルターに共に流入されて所望の脱塵効果に及ばれず、汚染物の脱離が不完全になされる問題点があった。   However, when the injector 20 that maximizes the Coanda effect is coupled to the lower part of the conduit 10 to which the compressed air is supplied, theoretically, air that is about 8 to 20 times the compressed air flows from the surroundings to the bag filter. In spite of having to be infused, the compressed air conduit 10 at the top of the injector 20 blocks the flow of ambient air, and in fact only air that is about 4-8 times the compressed air flows into the bag filter together. Thus, the desired dedusting effect is not achieved, and there is a problem that the desorption of contaminants is incomplete.

したがって、上記の問題点を解決するために、図６に示すように、上記インジェクター２０の上部にある圧縮空気の導管１０をインジェクター２０の側面部に固定させて圧縮空気が円型管３０及びスロット４０を段階的に経って、インジェクター２０に沿って排出されるようになっている。   Therefore, in order to solve the above problem, as shown in FIG. 6, the compressed air conduit 10 at the upper part of the injector 20 is fixed to the side surface of the injector 20 so that the compressed air flows into the circular tube 30 and the slot. After passing through 40, the fuel is discharged along the injector 20.

しかしながら、このような従来の圧縮空気噴射装置は、上記導管１０が一側に偏心して装着されるので、装置の均衡に問題があり、特に偏心された導管１０が外力を受ける場合、容易に破損される問題点があるだけではなく、空気がインジェクター２０の内に均一に配分されず、不完全な脱離が発生する問題点があった。   However, in such a conventional compressed air injection device, since the conduit 10 is mounted eccentrically on one side, there is a problem in the balance of the device, and particularly when the eccentric conduit 10 receives an external force, it is easily damaged. There is a problem that air is not uniformly distributed in the injector 20 and incomplete desorption occurs.

本発明は、上記のような従来の問題点を解決するためになされたものであって、その目的は、圧縮空気が供給される導管を２つに分岐して、このように分岐された分岐管の上部に圧縮空気を吸引して排出する増幅の割合が非常に高い空気増幅器を設けて、２つの分岐管の間を介して周辺空気がバグフィルターに共に供給されるようにすることで、バグフィルターに供給される空気の流れを妨げる装備を空気が流れる領域から完全に排除することからコアンダ効果を極大化して汚染物を完全に脱離する脱塵効果を著しく向上させることができる空気増幅器を利用した圧縮空気噴射装置を提供することである。   The present invention has been made in order to solve the above-described conventional problems, and its object is to divide a conduit to which compressed air is supplied into two, and the branch branched in this way. By providing an air amplifier with a very high amplification rate for sucking and discharging compressed air at the top of the tube so that ambient air is supplied to the bag filter via the two branch tubes, Air amplifier capable of maximizing the Coanda effect and removing dust completely, since the equipment that obstructs the flow of air supplied to the bag filter is completely eliminated from the air flow area. It is providing the compressed air injection device using the.

A branch pipe divided into two conduits with one end connected to the supply means, a compressed air pipe comprising a jet outlet through which the compressed air is ejected by perforating the upper surface of the branch pipe, and the two branch pipes A compressed air inlet that is formed at a position corresponding to each of the jet outlets and is coupled to the upper part of the two branch pipes by being coupled to the jet outlet, and air that is supplied to the compressed air inlet And an air amplifier comprising a compressed air discharge port for amplifying and discharging the air.

また、本発明に係る上記空気増幅器は、上記圧縮空気排出口が上記空気増幅器の内周面に沿って円型で側面に形成された第１ガイドと第２ガイドとの間の空間で構成され、上記第２ガイドから分岐管の下まで延長形成されて上記圧縮空気排出口から排出される圧縮空気の流れに沿って周辺空気を吸引してバグフィルターに伝達する誘導管からなることを特徴とする。   The air amplifier according to the present invention is configured by a space between a first guide and a second guide in which the compressed air discharge port is formed in a circular shape on a side surface along the inner peripheral surface of the air amplifier. The guide pipe is formed to extend from the second guide to the bottom of the branch pipe and sucks ambient air along the flow of compressed air discharged from the compressed air discharge port and transmits it to the bag filter. To do.

また、本発明に係る上記空気増幅器は、上記２つの分岐管に共にかけていて、上部は周辺空気を吸引するために中央部が開いているドーナツ状に形成され、その下部は上記第２ガイドから分岐管の下まで至る誘導管が管状に形成されたことを特徴とする。   In the air amplifier according to the present invention, the upper part is formed on the two branch pipes, the upper part is formed in a donut shape having an open central part for sucking ambient air, and the lower part is formed from the second guide. A guide tube extending under the branch tube is formed in a tubular shape.

また、本発明に係る上記空気増幅器に投入される圧縮空気と上記誘導管に排出する増幅された圧縮空気が垂直をなすように構成されたことを特徴とする。   Further, the present invention is characterized in that the compressed air supplied to the air amplifier according to the present invention and the amplified compressed air discharged to the guide tube are perpendicular to each other.

And the dust removal effect of contaminants attached to the bag filter can be remarkably improved.

以下、本発明の実施形態について図面に基づいて説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

本実施形態に係る空気増幅器を利用した圧縮空気噴射装置は、図１及び図２に示すように、圧縮空気の供給手段に連結されて２つの導管に分けられた圧縮空気管１００と、上記圧縮空気管１００の上部に結合して２つに分けられた圧縮空気管１００との間を介して圧縮空気と共に周辺空気を吸引して図４に示されたバグフィルター３００に供給する空気増幅器２００を含んで構成される。   As shown in FIGS. 1 and 2, the compressed air injection apparatus using the air amplifier according to the present embodiment is connected to a compressed air supply means and divided into two conduits, and the compressed air An air amplifier 200 that is coupled to the upper part of the air pipe 100 and sucks the ambient air together with the compressed air through the two compressed air pipes 100 and supplies the air to the bag filter 300 shown in FIG. Consists of including.

この時、上記バグフィルター３００(Ｂａｇ Ｆｉｌｔｅｒ)は、集塵機４００のハウジング内部に流入された空気を集塵するために複数個の複数列で設置され、不織布などからなるバッグ(Ｂａｇ)と、上記バッグの内部に備えられたバグケージ(Ｂａｇ Ｃａｇｅ)で構成される。   At this time, the bag filter 300 (Bag Filter) is installed in a plurality of rows to collect the air flowing into the housing of the dust collector 400, and is formed of a non-woven bag or the like, and the bag It is comprised by the bug cage (Bag Cage) with which it was equipped.

上記圧縮空気管１００は、従来のように上記バグフィルター３００の上側に一定距離離隔して設置され、圧縮空気供給手段に連結して圧縮された空気が供給されて伝達する管路をなす。また、上記圧縮空気供給手段も圧縮空気を蓄積する空気ヘッダー(図示せず)と、このヘッダーに結合された連結管に接続されたボール弁(図示せず)と、上記ボール弁の下側に設けられて上記圧縮空気管１００に供給される圧縮空気をパルシング(Ｐｕｌｓｉｎｇ)させるパルス弁(図示せず)を含んで構成される。   The compressed air pipe 100 is installed at a certain distance above the bag filter 300 as in the prior art, and is connected to a compressed air supply means to form a pipe line through which compressed air is supplied and transmitted. The compressed air supply means also has an air header (not shown) for storing compressed air, a ball valve (not shown) connected to a connecting pipe coupled to the header, and a lower side of the ball valve. A pulse valve (not shown) that is provided and pulsing the compressed air supplied to the compressed air pipe 100 is configured.

この時、上記圧縮空気管１００は、上記圧縮空気供給手段の連結部から２つに分岐されて２つの管路に分離した分岐管１１０で構成される。そして、上記分岐管１１０の上面には、上に穿孔されて圧縮空気が噴出される噴出口１２０が形成される。この場合、分岐管１１０の下部が密閉されることは勿論である。上記噴出口１２０は、分岐管１１０にかけて複数個が形成され、各噴出口１２０は圧縮空気管１００の中心線から垂直な方向に上記分岐管１１０にそれぞれ結合されることが望ましい。   At this time, the compressed air pipe 100 is composed of a branch pipe 110 that is branched into two from the connecting portion of the compressed air supply means and separated into two pipes. A spout 120 is formed on the upper surface of the branch pipe 110. The spout 120 is perforated upward and ejects compressed air. In this case, of course, the lower part of the branch pipe 110 is sealed. A plurality of the jet outlets 120 are formed over the branch pipe 110, and each jet outlet 120 is preferably coupled to the branch pipe 110 in a direction perpendicular to the center line of the compressed air pipe 100.

上記空気増幅器２００は、図３に示すように、上記分岐管１１０の上面に形成された噴出口１２０に結合される圧縮空気投入口２１０と、上記圧縮空気投入口２１０を介して流入された空気を一定倍率に増幅して側面に排出する圧縮空気排出口２２０が形成される。   As shown in FIG. 3, the air amplifier 200 includes a compressed air inlet 210 coupled to a jet outlet 120 formed on the upper surface of the branch pipe 110, and air that has flowed in through the compressed air inlet 210. Compressed air discharge port 220 is formed to amplify the air at a constant magnification and discharge it to the side surface.

この時、上記空気増幅器２００は、２つの分岐管１１０にかけて結合されていて、周辺空気がバグフィルター３００に吸引される通路は上記２つの分岐管１１０の間の空間内に備えられる。   At this time, the air amplifier 200 is coupled to the two branch pipes 110, and a passage through which ambient air is sucked into the bag filter 300 is provided in the space between the two branch pipes 110.

これによって、上記圧縮空気投入口２１０は、上記圧縮空気管１００の中心線から垂直な方向に２つの分岐管１１０にそれぞれ形成された噴出口１２０に結合されるように上記空気増幅器２００の底面に形成される。   Accordingly, the compressed air inlet 210 is formed on the bottom surface of the air amplifier 200 so as to be coupled to the outlets 120 formed in the two branch pipes 110 in a direction perpendicular to the center line of the compressed air pipe 100. It is formed.

また、上記圧縮空気排出口２２０は、圧縮空気管１００の内部中心線に向けるように上記２つの分岐管１１０での空気投入方向と約９０゜の角度をなして形成される。これによって、投入された空気が流れる通路をなす第１ガイド２２１と第２ガイド２２２が上記空気増幅器２００の内周面に沿って円型で側面に形成される。   The compressed air discharge port 220 is formed at an angle of about 90 ° with the air input direction in the two branch pipes 110 so as to face the inner center line of the compressed air pipe 100. Accordingly, the first guide 221 and the second guide 222 that form a passage through which the introduced air flows are formed in a circular shape on the side surface along the inner peripheral surface of the air amplifier 200.

そして、上記第２ガイド２２２から分岐管１１０の下に至るまで垂直に延長形成されて管をなす誘導管２３０がさらに形成される。それによって、上記第１ガイド２２１と第２ガイド２２２を介して排出される圧縮空気の流れに沿って上記空気増幅器２００の上部空間を満たす空気が周辺装備の邪魔にならず、バグフィルター３００の方向に共に吸引される。すなわち、上記分岐管１１０で圧縮空気投入口２１０を介して投入される空気の方向とは１８０゜対方に空気を排出してバグフィルターに付いている汚染物を脱離させるようになる。   In addition, a guide pipe 230 that extends vertically from the second guide 222 to below the branch pipe 110 to form a pipe is further formed. Accordingly, the air filling the upper space of the air amplifier 200 along the flow of compressed air discharged through the first guide 221 and the second guide 222 does not interfere with peripheral equipment, and the direction of the bag filter 300 Are sucked together. That is, air is discharged 180 degrees opposite to the direction of the air introduced through the compressed air inlet 210 in the branch pipe 110 to desorb contaminants attached to the bag filter.

上記空気増幅器２００は、２つの分岐管１１０にかけていて、中央部分は周辺空気を吸引するために穿孔されているドーナツ(ｄｏｎｕｔ)状で上部が形成され、その下部は上記第２ガイド２２２から分岐管１１０の下までに至る誘導管２３０が管状に形成される。   The air amplifier 200 extends over two branch pipes 110, and a central part is formed in a donut shape that is perforated to suck ambient air, and an upper part is formed from the second guide 222. A guide tube 230 extending down to 110 is formed in a tubular shape.

この時、上記噴出口１２０は、単純に穿孔された形状で構成され、上記圧縮空気投入口２１０が円型の管状で下部面が下に一定の長さに延長されて上記噴出口１２０の内部に挟まれた後、溶接或いはボルト結合によって堅く結合できることは勿論であり、その反対に上記噴出口１２０が分岐管１１０の上面に一定の長さに突出形成され、その噴出口１２０が単純に穿孔された上記圧縮空気投入口２１０の内部に挟まれた後、溶接或いはボルト結合によって堅く結合できることは勿論である。   At this time, the jet outlet 120 is configured to have a simple perforated shape, the compressed air inlet 210 has a circular tubular shape, and the lower surface extends downward to a certain length so that the inside of the jet outlet 120 is formed. Of course, after being sandwiched between the two pipes, it is possible to firmly connect them by welding or bolt connection. On the contrary, the jet port 120 is formed to protrude on the upper surface of the branch pipe 110 to a certain length, and the jet port 120 is simply perforated. Of course, the compressed air can be firmly connected by welding or bolting after being sandwiched inside the compressed air inlet 210.

以下、本実施形態に係る空気増幅器を利用した圧縮空気噴射装置の作用について説明する。   Hereinafter, an operation of the compressed air injection device using the air amplifier according to the present embodiment will be described.

図４に示すように、集塵機４００での集塵作用によって空気が浄化されてバグフィルター３００に汚染物が付着された後、間歇的または一定時間連続的に圧縮空気供給手段で２つに分岐された分岐管１１０を介して圧縮空気が供給される。このような圧縮空気は、上部に開放された噴出口１２０を介して供給され、このように供給される圧縮空気は、空気増幅器２００の圧縮空気投入口２１０を介して空気増幅器２００に流入される。   As shown in FIG. 4, after the air is purified by the dust collecting action of the dust collector 400 and the contaminant is attached to the bag filter 300, it is branched into two by the compressed air supply means intermittently or continuously for a certain time. Compressed air is supplied through the branch pipe 110. Such compressed air is supplied through the jet outlet 120 opened to the top, and the compressed air supplied in this way flows into the air amplifier 200 through the compressed air inlet 210 of the air amplifier 200. .

上記空気増幅器２００は、投入された圧縮空気を増幅させて上記分岐管１１０の中心線に向けて内側方向に側面に形成された圧縮空気排出口２２０を介して排出される。この時、上記空気増幅器２００の第１ガイド２２１と第２ガイド２２２を介してその排出方向が案内され、空気増幅器２００から排出される方向は図３の点線（２）のように上記圧縮空気投入口２１０を介して投入された方向の点線（１）とは異なる平面上で約９０゜の角度をなして排出される。   The air amplifier 200 amplifies the input compressed air and discharges it through a compressed air discharge port 220 formed on a side surface inwardly toward the center line of the branch pipe 110. At this time, the discharge direction is guided through the first guide 221 and the second guide 222 of the air amplifier 200, and the discharge direction from the air amplifier 200 is the input of the compressed air as shown by the dotted line (2) in FIG. It is discharged at an angle of about 90 ° on a plane different from the dotted line (1) in the direction of injection through the mouth 210.

また、排出される圧縮空気は、上記第２ガイド２２２と誘導管２３０に沿って点線（３）の方向に流れるようになり、それと共に上記空気増幅器２００の上部で制裁を受けない自由状態の周辺空気が点線（４）の方向に共に流れるようになる。   The discharged compressed air flows in the direction of the dotted line (3) along the second guide 222 and the guide tube 230, and at the same time, is free from being sanctioned at the top of the air amplifier 200. Air flows together in the direction of the dotted line (4).

すなわち、上記空気増幅器２００で増幅された圧縮空気がその上部の空気を共に吸引して誘導管２３０に沿ってバグフィルター３００の方向に供給され、上記圧縮空気供給手段から供給されたものに比べて約２０〜４０倍に至る多量の空気がバグフィルター３００に供給されて脱塵作用の効率を増加させる。この時、上記周辺空気が吸引される空気増幅器２００の上部には、他の設備がないので、周辺設備による障害を最小化して空気増幅器２００での増幅効率がそのまま示される。   That is, the compressed air amplified by the air amplifier 200 sucks together the air above it and is supplied in the direction of the bag filter 300 along the induction tube 230, compared with that supplied from the compressed air supply means. A large amount of air, approximately 20 to 40 times, is supplied to the bag filter 300 to increase the efficiency of the dust removal action. At this time, since there is no other equipment above the air amplifier 200 where the ambient air is sucked in, the amplification efficiency in the air amplifier 200 is shown as it is by minimizing the obstacles due to the peripheral equipment.

一方、圧縮空気の導管が上記誘導管２３０を中心に両側に分岐された分岐管１１０形態で均衡に形成されるので、誘導管２３０に流入される圧縮空気が均一に分配、供給されて不完全な脱離の発生を防止するようになる。   On the other hand, the compressed air conduit is formed in a balanced manner in the form of the branch pipe 110 branched on both sides around the guide pipe 230, so that the compressed air flowing into the guide pipe 230 is evenly distributed and supplied.
