Description

本発明は、水蒸気や油の蒸気、あるいはアルコール等の溶剤の蒸気が発生する作業を行うに際し、周囲に蒸気を拡散させることなく排出することができる蒸気排出装置に関し、詳しくはその蒸気発生作業が連続する場合にも1基ないし少ない基数で対処可能とした蒸気排出装置に関する。   The present invention relates to a steam discharge device that can discharge steam without diffusing steam in the surroundings when performing an operation that generates steam of steam, oil, or a solvent such as alcohol. The present invention relates to a steam discharge device that can cope with one or a small number even in a continuous case.

食品工場、例えば弁当製造工場では、米やおかずの煮炊きの工程あるいは揚げ物の調理工程で、水や油の蒸気が発生する。従来、炊飯や煮物に伴って発生する水蒸気は、工場の建屋の天井や壁に設けられた換気扇によって外部に排出し、揚げ物に伴って発生する油の蒸気は、揚げ物製造器(フライヤー)の油槽の上方にフードを設置して、フードの裏面に取り付けられた排気ファンによって吸引し、油の蒸気をフードに取り付けられた専用のダクトにより建屋の外に導いて排出するのが一般的である。   In a food factory, for example, a lunch box manufacturing factory, steam of water or oil is generated in the cooking process of rice or side dishes or the cooking process of fried food. Conventionally, steam generated with cooked rice and boiled food is discharged to the outside by a ventilation fan installed on the ceiling or wall of the factory building, and the oil vapor generated with fried food is the oil tank of a fried food maker. In general, a hood is installed above the hood, sucked by an exhaust fan attached to the back surface of the hood, and oil vapor is guided out of the building by a dedicated duct attached to the hood and discharged.

ところで、溶接等の作業を行う空間を囲むようにして複数本の空気吹き出しパイプを平行に配置して、各パイプから隣接する一方のパイプ方向にほぼ向けて空気を吹き出すと共に、排気手段により空間の上方から空気を強制排気することにより、空間内に吸気口に至る速度分布がシャープな竜巻気流を形成して、溶接等の作業に伴って発生する有害ガス等を、周囲に拡散させずに竜巻気流に随伴させて空間から移送し、排気手段のダクトにより外部に排出するようにした有害ガス等拡散防止装置が提案されている(例えば特許文献1を参照)。   By the way, a plurality of air blowing pipes are arranged in parallel so as to surround a space for performing an operation such as welding, and air is blown out from each pipe toward one of the adjacent pipes, and from above the space by the exhaust means. By forcibly exhausting air, a tornado airflow with a sharp velocity distribution leading to the intake port is formed in the space, and harmful gases generated during work such as welding are not diffused to the tornado airflow. There has been proposed a diffusion preventing apparatus for harmful gases, etc., which is transferred from the space in association with the exhaust and discharged to the outside by a duct of an exhaust means (see, for example, Patent Document 1).

この提案によれば、蒸気の発生が伴う作業を行う空間、例えば揚げ物器を含む周囲の空間を空気吹き出しパイプで囲んで蒸気排出装置を構築することにより、揚げ物に伴う油の蒸気を周囲に拡散させずに効率よく移送して、工場の建屋の外部に排出することができる。   According to this proposal, a steam discharge device is constructed by enclosing a space in which work involving the generation of steam, for example, a surrounding space including a frying device, is surrounded by an air blowing pipe, thereby diffusing oil vapor accompanying the fried food to the surroundings. It can be transferred efficiently and discharged outside the factory building.

しかしながら、この提案による排出装置は、基本的に、蒸気発生作業工程ごとに設置しなければならず、対象物に対し蒸気発生作業を例えば2工程連続して行う場合に、それらの蒸気の排出に1基の排出装置で対処して省力化するようにはできなかった。
特公平4−11769号
However, the discharge device according to this proposal must basically be installed for each steam generation work process. For example, when performing steam generation work on an object in two consecutive steps, the discharge of those steam is performed. It was not possible to save labor by dealing with one discharge device.
JP 4-117769

したがって、本発明の課題は、水蒸気や油の蒸気、あるいはアルコール等の溶剤の蒸気が発生する作業を、対象物に対し例えば2工程連続して行う場合にも対処して、その蒸気を周囲に拡散させることなく排出することができ、装置を省力化することができる蒸気排出装置を提供することである。   Accordingly, an object of the present invention is to cope with the case where the operation of generating vapor of water vapor, oil vapor, or solvent such as alcohol is performed continuously on an object, for example, in two steps, and the vapor is introduced to the surroundings. It is an object of the present invention to provide a vapor discharge device that can be discharged without being diffused and can save the device.

上記課題を達成するために、本発明の蒸気排出装置は、各パイプが隣接する一方のパイプにほぼ向いた方向に空気を吹き出す、4本の空気吹き出しパイプと、前記空気吹き出しパイプを四隅に配置することによって内側に区画された長方形の水平断面を有する空間に上方から吸気口を臨ませた排気手段と、前記空間に存在する蒸気の凝縮液を捕捉する、前記吸気口の下方に配置されたドレンパンとを備え、前記ドレンパンは、前記空気吹き出しパイプ同士を結ぶ仮想の長方形の長手方向の中央であって上方の高さ位置に配置され、前記空気吹き出しパイプから空気を吹き出すと共に、前記吹き出した空気を、前記排気手段により前記空間の上方から強制排気することによって、前記空間内に前記吸気口に至る前記空間の長方形の長手方向を二分した部分にそれぞれ竜巻気流を形成し、前記空間に存在する蒸気を前記竜巻気流に随伴して排出させるようにしたことを特徴とする。 To achieve the above object, the steam discharge apparatus of the present invention, each pipe blowing air in the direction facing substantially in one of the pipe adjacent, four and air blowoff pipe, the air blowout pipe four corners an exhaust means to face the air inlet from above the space having a rectangular horizontal cross section is divided into inside by placing, capturing the condensate of the vapor existing in the space, it is disposed below the air inlet The drain pan is disposed at the upper center position in the longitudinal direction of the virtual rectangle connecting the air blowing pipes, and blows air from the air blowing pipe and blows out the air. the air, by forcibly exhausted from above the space by the front Symbol exhaust means, a rectangular longitudinal direction of the space leading to the air inlet in the space two And portions respectively form a tornado airflow was characterized by the vapor present in the space and so as to be discharged to accompany the tornado flow.

本発明者等は、対象物に対し蒸気の発生が伴う作業が複数工程連続する場合にも、1基の蒸気排出装置で対処可能とするべく鋭意研究を重ねたところ、次のことを知見した。即ち、蒸気が発生する作業を行う場合、発生した蒸気を凝縮して捕捉するために、蒸気発生作業を行う空間の上方にドレンパンを配置し、複数本の空気吹き出しパイプから隣接する一方のパイプ方向に空気を吹き出すと共に、吹き出した空気を空間の上方から強制排気し、吸気口の下方に前記ドレンパンを位置して、蒸気排出装置を運転する際、ドレンパンの空間的影響の存在下に空気を排気すると、空間内に吸気口に至る竜巻気流が複数形成されることを見出した。   The inventors of the present invention have made extensive studies to make it possible to deal with a single object with a single steam discharge device even when a plurality of processes involving generation of steam are continuously performed on the object. . That is, when performing work that generates steam, in order to condense and capture the generated steam, a drain pan is disposed above the space where the steam generation work is performed, and the direction of one adjacent pipe from a plurality of air blowing pipes The air is blown out from the top of the space, and the drain pan is positioned below the intake port, and when the steam discharge device is operated, the air is exhausted in the presence of the spatial influence of the drain pan. As a result, it was found that a plurality of tornado airflows reaching the air inlets were formed in the space.

本発明は、上記知見に基づいて得られたものである。空気吹き出しパイプで囲まれた空間内に発生する竜巻気流は、気流の中心の速度が周囲に比べて非常に速いシャープな速度分布を有しているので、排気手段を強力にしないでも、空間に存在する蒸気を巻き込んで、周囲に拡散させることなく吸気口に効率的に移送でき、蒸気を排気手段のダクト等を介して外部の適当な場所に排出することができる。その竜巻気流が、空気吹き出しパイプで囲まれた空間内に複数形成されるので、対象物に対し蒸気発生作業が連続して複数工程続く場合にも、1基の蒸気排出装置で対処することも可能になり、装置を省力化することができる。   The present invention has been obtained based on the above findings. The tornado airflow generated in the space surrounded by the air outlet pipe has a sharp velocity distribution in which the velocity of the center of the airflow is very fast compared to the surroundings. The existing steam can be efficiently transferred to the intake port without being diffused to the surroundings, and the steam can be discharged to an appropriate external location through a duct or the like of the exhaust means. A plurality of the tornado airflows are formed in the space surrounded by the air blowing pipes, so even if the steam generation operation continues for a plurality of processes on the target object, it is possible to deal with one steam discharge device. This makes it possible to save the apparatus.

この竜巻気流の発生個数および発生位置は、空気吹き出しパイプが囲む空間の大きさ、パイプの本数、各パイプは隣接するパイプのうちの一方のパイプの方向に空気を吹き出すが、そのいずれのパイプ方向に吹き出すかの空気の吹き出し方向、吹き出す空気の流量および流速、ドレンパンの設置位置等の蒸気排出装置の構成要素の条件および装置の運転条件によって変わるので、対象物に対する蒸気が発生する作業の連続工程数等を具体的に考慮して、必要な竜巻気流の発生個数および適当な発生位置が得られるように、これらの条件を実験的に決定する。そして求められた条件に基づいて、蒸気が発生する作業を行う開放されたブースに蒸気排出装置を構築し、空気吹き出しパイプで囲まれた空間内の竜巻気流が発生する個々の場所を、連続した複数工程の蒸気発生作業の個々の工程の作業場所と定めて、求めた条件で蒸気排出装置を運転し、個々の作業場所に対象物を順次移動させながら、対象物に対し各工程の蒸気発生作業を行うことになる。   The number and location of the tornado airflow are as follows: the size of the space enclosed by the air blowing pipe, the number of pipes, and each pipe blows air in the direction of one of the adjacent pipes. The process of generating steam for the target object varies depending on the conditions of the components of the steam discharge device and the operating conditions of the device, such as the air blowing direction, the flow rate and flow rate of the blown air, the installation position of the drain pan, etc. These conditions are experimentally determined so that the necessary number of generated tornado airflows and appropriate generation positions can be obtained by specifically considering the number and the like. Based on the required conditions, a steam discharge device was constructed in an open booth where the work of generating steam was performed, and individual locations where tornado airflow was generated in the space surrounded by the air blowing pipes By defining the work place of each process of the multi-stage steam generation work, operating the steam discharge device under the obtained conditions, moving the object sequentially to each work place, generating steam for each process on the object Will work.

本発明によれば、対象物に対し蒸気が発生する作業を複数工程連続して行う場合に、その各工程で生じる蒸気を周囲に拡散させることなく排出できるために、1基ないし少ない基数の蒸気排出装置で対処することが可能になり、蒸気排出装置を省力化することができる。   According to the present invention, when the operation of generating steam for an object is continuously performed for a plurality of processes, the steam generated in each process can be discharged without diffusing to the surroundings. It becomes possible to deal with the discharge device, and the steam discharge device can be saved.

図1は、本発明の蒸気排出装置の一実施例を示す一部切欠き平面図、図2は、同装置の一部切欠き正面図、図3は、同装置の一部切欠き側面図、図4は、本装置で発生する竜巻気流を模式的に示す平面図である。   FIG. 1 is a partially cutaway plan view showing an embodiment of the steam discharge device of the present invention, FIG. 2 is a partially cutaway front view of the device, and FIG. 3 is a partially cutaway side view of the device. FIG. 4 is a plan view schematically showing a tornado airflow generated in the present apparatus.

図において、符号8は湯せん浴、1は湯せん浴8上に設置された蒸気排出装置を示す。湯せん浴8は内側の下部に図示しないプラグヒータを備え、湯せん浴8内に張った水をプラグヒータで例えば約80℃の湯に加熱して、湯の熱で図示しない容器に入れた例えば原色塗料を加熱しながら、着色剤による塗料の調色を2工程で行うのに使用される。そのために、湯せん浴8の長手方向を2等分する各領域で、連続して塗料の調色を行えるように、横に長く形成している。蒸気排出装置1は、それぞれの調色工程で発生した溶剤蒸気を排出するのに使用される。   In the figure, reference numeral 8 denotes a hot water bath, and 1 denotes a steam discharge device installed on the hot water bath 8. The hot water bath 8 is provided with a plug heater (not shown) at the inner lower part, and the water stretched in the hot water bath 8 is heated to hot water of, for example, about 80 ° C. with the plug heater, and is placed in a container (not shown) with the heat of the hot water, for example It is used for toning the paint with a colorant in two steps while heating the paint. Therefore, the hot water bath 8 is formed to be long in the side so that the color of the paint can be continuously adjusted in each region that bisects the longitudinal direction of the hot water bath 8. The vapor discharge device 1 is used to discharge the solvent vapor generated in each color matching process.

本実施例の蒸気排出装置1は、湯せん浴8の四隅に4本の空気吹き出しパイプP1〜P4を立設し、パイプP(P1〜P4)にフード3を被せて該パイプPの上端部を貫通させるとともに、フード3の上端中央の吸気用の開口3aに図示しない強制排気手段に接続されたダクト4の吸気口を臨ませ、ダクト4の下方にドレンパン5を配置してなっている。   In the steam discharge device 1 of this embodiment, four air blowing pipes P1 to P4 are erected at the four corners of the hot water bath 8, and the pipe P (P1 to P4) is covered with the hood 3 so that the upper end of the pipe P is covered. In addition to passing through, an intake port of a duct 4 connected to a forced exhaust means (not shown) faces an intake opening 3 a in the center of the upper end of the hood 3, and a drain pan 5 is disposed below the duct 4.

湯せん浴8の四隅には、パイプPよりも短い縦方向のアングル2が取り付けられ、この各アングル2の内側に各パイプPを支持させることによって、パイプPは湯せん浴8の四隅に立設されている。4本のアングル2の上端には長方形の細い支持枠6を設け、支持枠6上にフード3を載置して取り付けている。また前後のアングル2同士の間には側板7を取り付けている。この側板7は、アングル2と支持枠6とで組立てられた4本のパイプPとフード3とからなる構造体の補強のために設けており、構造体の組立て強度が十分ならば側板7は不要である。   The vertical angles 2 shorter than the pipes P are attached to the four corners of the hot water bath 8, and the pipes P are erected at the four corners of the hot water bath 8 by supporting the pipes P inside the angles 2. ing. A rectangular thin support frame 6 is provided at the upper ends of the four angles 2, and the hood 3 is mounted on the support frame 6. A side plate 7 is attached between the front and rear angles 2. The side plate 7 is provided to reinforce the structure composed of the four pipes P and the hood 3 assembled by the angle 2 and the support frame 6. If the assembly strength of the structure is sufficient, the side plate 7 It is unnecessary.

フード3は、傾斜角度が例えば30°の台形状の屋根部3bの下端に長方形のスカート部3cを接続した形状をしている。本発明では、パイプPから吹き出した空気によって竜巻気流を形成させて、空気を竜巻気流の形で排気させるから、排気手段による排気効率はフード3を設けなくても高い。したがって、フード3は必ずしも必要ではないが、フード3があれば、その分だけ排気効率が高くなる。   The hood 3 has a shape in which a rectangular skirt portion 3c is connected to the lower end of a trapezoidal roof portion 3b having an inclination angle of, for example, 30 °. In the present invention, the tornado airflow is formed by the air blown out from the pipe P, and the air is exhausted in the form of the tornado airflow. Therefore, the exhaust efficiency by the exhaust means is high without providing the hood 3. Therefore, the hood 3 is not always necessary, but if the hood 3 is present, the exhaust efficiency is increased accordingly.

パイプPの先端部は、フード3のスカート部3cを貫通して上方に延出され、各パイプPの延出された先端部には、空気圧送手段からの空気送りパイプ(共に図示せず)が接続されている。湯せん浴8とフード3との間には、4本のパイプPによって囲まれる空間Hが区画されている。各パイプPには、空間Hに位置する部分、即ち湯せん浴8の上面よりわずかに上の位置から支持枠6までの部分に、1.5mm径の空気吹き出し孔h(図4)が100mmピッチで1列に設けられている。各パイプPの吹き出し孔hは、水平方向に吹き出し空気が空間Hを囲むように、隣接する一方のパイプ方向に向けられるが、多少内側に傾斜させると竜巻気流が形成しやすくなる。本実施例では、各パイプPからの空気吹き出し方向は、P1→P2およびP4→P3、P4→P3およびP3→P2とし、それぞれ内側に30°傾斜させた。なお、パイプPは呼び径100mmの塩ビパイプで、全長が800mm、パイプPの下端から支持枠6までの長さが1400mm、フード3からの突出長が300mmである。   The tip of the pipe P passes through the skirt 3c of the hood 3 and extends upward, and the extended tip of each pipe P has an air feed pipe from the pneumatic feed means (both not shown). Is connected. A space H surrounded by four pipes P is defined between the hot water bath 8 and the hood 3. Each pipe P has air blow holes h (FIG. 4) having a diameter of 1.5 mm at a pitch of 100 mm in a portion located in the space H, that is, a portion from a position slightly above the upper surface of the hot water bath 8 to the support frame 6. In one row. The blowing hole h of each pipe P is directed in the direction of one adjacent pipe so that the blowing air surrounds the space H in the horizontal direction. In this embodiment, the air blowing directions from the pipes P were P1 → P2 and P4 → P3, P4 → P3 and P3 → P2, respectively, and were inclined 30 ° inward. The pipe P is a polyvinyl chloride pipe having a nominal diameter of 100 mm, the total length is 800 mm, the length from the lower end of the pipe P to the support frame 6 is 1400 mm, and the protruding length from the hood 3 is 300 mm.

ドレンパン5は、フード3の屋根部3bの裏面にロッド5aで吊り下げて、フード3内で開口3aの下方に位置されている。本実施例では、ドレンパン5は、1辺が440mm、深さが40mmの角皿状とし、開口3aからの距離を250mmとした。このドレンパン5は、湯せん浴8で蒸気の発生が伴う作業を行う場合に、発生した蒸気が凝縮したものを捕捉する役目があり、一つにはそのために設けるが、パイプPから吹き出した空気により空間Hに2つの渦巻気流を形成させる重要な役目もあり、そのためにも設ける。この後者の作用は、パイプPから吹き出した空気を空間Hの上方から強制排気したときに、その空間Hの上方近くにドレンパン5が存在すると、ドレンパン5が空間H内の空気の流れに対し空間的な影響を及ぼし、2つの渦巻気流を形成させるように働くものと思われる。したがって、本発明では、「ドレンパン」の語は、作業に伴って発生した蒸気を空間Hの上方で凝縮、捕捉させるためのものに限定されず、空間H内の空気の流れに対し空間的影響を及ぼす構造物をも包含する。   The drain pan 5 is hung on the back surface of the roof portion 3 b of the hood 3 by a rod 5 a and is positioned below the opening 3 a in the hood 3. In this embodiment, the drain pan 5 has a square plate shape with one side of 440 mm and a depth of 40 mm, and the distance from the opening 3 a is 250 mm. This drain pan 5 has a role of capturing the condensed steam generated when steam is generated in the hot water bath 8, and is provided for this purpose. There is also an important role of forming two spiral airflows in the space H, and it is also provided for this purpose. The latter action is that when the air blown out from the pipe P is forcibly exhausted from above the space H and the drain pan 5 is present near the upper portion of the space H, the drain pan 5 is in space against the air flow in the space H. It seems that it works to form two spiral airflows. Therefore, in the present invention, the term “drain pan” is not limited to condensing and trapping the vapor generated during the work above the space H, but has a spatial effect on the air flow in the space H. It also includes structures that affect

なお、湯せん浴8はステンレス製で、長さが1900mm、幅が800mm、高さが500mmである。浴8の一方の側壁には排水用タッピング8aが取り付けられている。フード3は高さが500mmで、上端の開口3aは1辺が350mmの角形であり、これにダクト4の先端の吸気口が接続具を介して取り付けられている。蒸気排出装置1は、パイプPからの空気吹き出し流量を例えば720〜880m3/hour、排気手段による空気排気流量を例えば2100〜2500m3/hourで運転する。 The hot water bath 8 is made of stainless steel, has a length of 1900 mm, a width of 800 mm, and a height of 500 mm. A drain tapping 8 a is attached to one side wall of the bath 8. The hood 3 has a height of 500 mm, and the opening 3 a at the upper end has a square shape with a side of 350 mm, and the air inlet at the tip of the duct 4 is attached to this via a connector. The steam discharge device 1 operates at an air blowing flow rate from the pipe P of, for example, 720 to 880 m 3 / hour, and an air exhaust flow rate of the exhaust means of, for example, 2100 to 2500 m 3 / hour.

本実施例では、蒸気排出装置1を上記諸元および条件で構築して運転した。これにより、パイプPから空間H内へ空気を吹き出し、吹き出した空気を空間Hの上方から強制排気すると、ドレンパン5の空間的影響により、空間H内には、その長方形の長手方向を2等分した領域に、パイプP1、P2から吹き出した空気による竜巻気流Q1と、パイプP3、P4から吹き出した空気による竜巻気流Q2の2つが発生し、湯せん浴8の上面をほぼ半分ずつ覆うように形成された。これらの竜巻気流は、空間H内を旋回しながら上昇するに連れて半径が急激に縮小し、気流中心の速度が急速に増した気流になっており、空間Hからフード3の開口3aに至る。   In this example, the steam discharge device 1 was constructed and operated with the above specifications and conditions. Thereby, when air is blown out from the pipe P into the space H and the blown-out air is forcibly exhausted from above the space H, the longitudinal direction of the rectangle is divided into two equal parts in the space H due to the spatial effect of the drain pan 5. The tornado airflow Q1 caused by the air blown from the pipes P1 and P2 and the tornado airflow Q2 caused by the air blown from the pipes P3 and P4 are generated in the region, and are formed so as to cover almost half of the upper surface of the hot water bath 8. It was. These tornado airflows are airflows in which the radius rapidly decreases as they rise while turning in the space H, and the velocity at the center of the airflow increases rapidly. From the space H to the opening 3 a of the hood 3. .

このような竜巻気流によれば、排気手段を強力にしないでも、空間H内に存在する蒸気を巻き込んで、空間Hから周囲に拡散させることなく効率よくフード3の開口3aに移送することができる。したがって、湯せん浴8の長手方向を2分した2つの領域で、連続して塗料の調色を行い、その各調色作業で塗料から溶剤が蒸発して空間H内に移行すると、空間H内には湯せん8の各領域上に竜巻気流Q1、Q2が発生しているので、溶剤の蒸気は竜巻気流によって空間Hから移送され、フード3の開口3aからダクト4を通って外部のガス処理装置などの適当な場所に排出され、空間Hから周囲に拡散することがない。   According to such a tornado airflow, the steam existing in the space H can be entrained and efficiently transferred from the space H to the opening 3a of the hood 3 without enlarging the exhaust means. . Therefore, in the two areas obtained by dividing the longitudinal direction of the hot water bath 8 into two, the paint is continuously toned, and when the solvent evaporates from the paint and moves into the space H in each of the toning operations, Since the tornado airflows Q1 and Q2 are generated on each area of the hot water bath 8, the solvent vapor is transferred from the space H by the tornado airflow, and passes through the duct 4 from the opening 3a of the hood 3 to the external gas processing device. It is discharged to an appropriate place such as, and does not diffuse from the space H to the surroundings.

以上のように、本実施例によれば、湯せん浴を2等分した2つの領域での溶剤の蒸気の発生を伴う2工程の作業に、1基の蒸気排出装置で対処して、各工程で発生した溶剤の蒸気を周囲に拡散させることなく排出することができ、蒸気排出装置を省力化することができる。   As described above, according to this embodiment, a single steam exhausting device copes with a two-step operation involving generation of a solvent vapor in two regions obtained by dividing a hot water bath into two equal parts. It is possible to discharge the solvent vapor generated in step 1 without diffusing to the surroundings, and to save labor in the vapor discharge device.
