この発明は合成繊維の熱処理装置等のように熱媒蒸気で
被処理物を加熱する形式の加熱装置の改良に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a heating device that heats an object to be treated using heat medium vapor, such as a heat treatment device for synthetic fibers.
更に詳しくは、熱媒液容器の内側底部に熱媒液を入れ、
該熱媒液の自由表面上に熱媒蒸気室を形成した加熱装置
である。More specifically, the heating medium liquid is poured into the inner bottom of the heating medium liquid container,
This heating device has a heat medium vapor chamber formed on the free surface of the heat medium liquid.
従来からこの種装置として知られているものは、密閉容
器の上部に凝縮槽を連通し、下部に熱媒液容器を連通し
、該熱媒液容器に収納された熱媒液中に電熱ヒータを没
入させたものであった。Conventionally known devices of this type include a condensing tank connected to the upper part of a closed container, a heat medium liquid container connected to the lower part, and an electric heater in the heat medium liquid stored in the heat medium liquid container. It was an immersive experience.
しかし、このような装置は、種々の利点を有すると共に
次のような欠点を持っていた。However, while such devices have various advantages, they also have the following disadvantages.
即ち、該熱媒液は電熱ヒータによる、対流によって昇温
するのでまず多量の熱媒液を要する。That is, since the heat medium liquid is heated by convection caused by the electric heater, a large amount of heat medium liquid is first required.
更に上記のように電熱ヒータでその周囲の熱媒液を加熱
し、対流作用で熱媒液全体の温度を高め、蒸発温度に達
したとき蒸発を行うもので、そのため蒸発を行うまでに
時間を要する。Furthermore, as mentioned above, the electric heater heats the surrounding heat medium liquid, raises the temperature of the entire heat medium liquid by convection, and evaporates when it reaches the evaporation temperature, so it takes time to evaporate. It takes.
又、熱媒液の液面より下方で加熱されるから突沸現象が
生じ易く、この際の液滴が飛散して、加熱装置の熱交換
面に直接衝突し、この部分の温度を局部的に上昇させ、
温度むらを生じることがあった。In addition, since the heat transfer liquid is heated below the liquid level, bumping phenomenon tends to occur, and the droplets at this time scatter and collide directly with the heat exchange surface of the heating device, causing the temperature of this part to locally increase. let it rise;
Temperature irregularities could occur.
更にまた発生した熱媒蒸気中の低沸点物質が、前記竪長
密閉容器の上方内部に停滞し、前記凝縮槽への移行速度
が遅く、このため熱交換面において上下に温度むらを生
ずることがあった。Furthermore, the low boiling point substances in the heat medium vapor generated remain in the upper interior of the vertical closed container, and the speed of transfer to the condensing tank is slow, which may cause temperature unevenness in the upper and lower portions of the heat exchange surface. there were.
この発明は、上記の諸問題点を解決するためのものであ
る。This invention is intended to solve the above problems.
これを図について説明すると、複数の竪長密閉容器１を
等間隔に並べ、それらの各竪長密閉容器１の上部を、パ
イプ２０により、一本の横長の凝縮槽２に連通する、そ
して、該パイブ２０には狭搾部２１を形成する。To explain this with reference to the diagram, a plurality of vertical sealed containers 1 are arranged at equal intervals, and the upper part of each vertical sealed container 1 is communicated with one horizontally long condensation tank 2 through a pipe 20. A narrowed portion 21 is formed in the pipe 20.
また上記竪長密閉容器１の下部を一本の横長熱媒液容器
３に連通し、そして前記凝縮槽２と、前記横長熱媒液容
器３とを戻しパイプ２２によって連通するのである。Further, the lower part of the vertical closed container 1 is communicated with one horizontally long heat medium liquid container 3, and the condensing tank 2 and the horizontally long heat medium liquid container 3 are connected through a return pipe 22.
次に前記横長熱媒液容器３内に、熱媒液５を収納し、該
熱媒液５の自由表面に沿って横長の電熱ヒータ４を設け
、その電熱ヒータ１の下面部６を熱媒液６中に浸漬し、
上面部７を熱媒液５の自由表面８上の熱媒蒸気室９に露
出せしめ、更に前記電熱ヒータ４の外周に耐熱性多孔質
層１０を形成する。Next, a heat medium liquid 5 is stored in the horizontally long heat medium liquid container 3, and a horizontally long electric heater 4 is provided along the free surface of the heat medium liquid 5. Immerse in liquid 6,
The upper surface portion 7 is exposed to the heat medium vapor chamber 9 on the free surface 8 of the heat medium liquid 5, and a heat-resistant porous layer 10 is further formed around the outer periphery of the electric heater 4.
熱媒液５中に浸漬された電熱ヒータ４の外周と多孔質層
１０との間で形成される空間１１は、その熱媒液５で允
満され、又熱媒液５の自由表面８上に露出された電熱線
４の外面と多孔質層１０との間に形成された薄い空間に
も毛細管現象により熱媒液５で允満される。The space 11 formed between the outer periphery of the electric heater 4 immersed in the heat transfer liquid 5 and the porous layer 10 is filled with the heat transfer liquid 5, and the free surface 8 of the heat transfer liquid 5 is The thin space formed between the exposed outer surface of the heating wire 4 and the porous layer 10 is also filled with the heating medium liquid 5 due to capillarity.
斯様にして電熱ヒータ４の全外面は熱媒液５の薄層で覆
われる。In this way, the entire outer surface of the electric heater 4 is covered with a thin layer of heat transfer liquid 5.
電熱ヒータ４はその内部に電熱線１５と耐熱性電気絶縁
物１６を持っており、電熱線１５に電気を流して電熱ヒ
ータ４の温度を上昇すると、空間１２内の薄層状熱媒液
５は電熱ヒータ４に面接触した状態で加熱される。The electric heater 4 has a heating wire 15 and a heat-resistant electric insulator 16 inside thereof, and when electricity is passed through the heating wire 15 to raise the temperature of the electric heater 4, the thin layer heat medium liquid 5 in the space 12 changes. It is heated while in surface contact with the electric heater 4.
即ち、薄膜状の僅かの量の熱媒液が、電熱ヒータ４から
伝導熱によって加熱され、たちまち気化され、蒸気とな
って蒸気室９に上昇する。That is, a small amount of the heat medium liquid in the form of a thin film is heated by conduction heat from the electric heater 4, is immediately vaporized, and rises to the steam chamber 9 as vapor.
空間１２内の熱媒液５が蒸気になると同時に、この空間
１２内には熱媒液５の自由表面８より下位に存在する熱
媒液５が、毛細管現象によって補充される。At the same time that the heating medium liquid 5 in the space 12 turns into vapor, the heating medium liquid 5 present in this space 12 below the free surface 8 of the heating medium liquid 5 is replenished by capillary action.
空間１２内に於ける薄膜状熱媒液５の蒸発と、毛細管作
用による補充が同時に且つ連続的に行われ、蒸気室９内
を熱媒蒸気で允満し、更にこの蒸気室９と連通せる複数
の竪長密閉容器１内の蒸気室１４も允満する。Evaporation of the thin film heat medium liquid 5 in the space 12 and replenishment by capillary action are performed simultaneously and continuously, filling the steam chamber 9 with heat medium vapor and further communicating with the steam chamber 9. The steam chambers 14 in the plurality of vertical closed containers 1 are also filled.
この竪長密閉容器１の蒸気室１４に存在する熱媒蒸気の
熱で熱交換面１７に接している被処理物を加熱する。The object to be treated that is in contact with the heat exchange surface 17 is heated by the heat of the heat medium vapor existing in the steam chamber 14 of the vertical closed container 1 .
この際の熱交換作用によって温度の低下した熱媒蒸気は
再び液化し、容器１内を落下して熱媒容器３内に戻る。The heat medium vapor whose temperature has decreased due to the heat exchange action at this time is liquefied again, falls inside the container 1, and returns to the heat medium container 3.
従って、熱媒液５の量は変化せず電熱ヒータ４の下面６
を浸漬できる程度あれば充分であり、極めて少量で済み
経済的である。Therefore, the amount of the heat transfer liquid 5 does not change and the lower surface 6 of the electric heater 4
It is sufficient if the amount can be immersed in the water, and it is economical since only a very small amount is required.
竪長密閉容器１の熱交換面１７には必要に応じて通糸用
溝１８を形成して、被熱処理糸１９のガイドとする。A thread threading groove 18 is formed as necessary on the heat exchange surface 17 of the vertical closed container 1 to serve as a guide for the thread 19 to be heat treated.
又前記のように、各竪長密閉容器１の上部と横長凝縮槽
２とはパイプ２０で連通してある。Further, as described above, the upper part of each vertical closed container 1 and the horizontally long condensing tank 2 are communicated with each other through the pipe 20.
次に横長凝縮槽２は他の部分より保温対策を少くしてあ
るので、外部への自然放熱で温度が低下し、その凝縮槽
２内の熱媒蒸気は冷却されて凝縮し、その内部の圧力が
低下し、竪長密閉容器１内の熱媒蒸気を横長凝縮槽２内
に吸引する。Next, since the horizontally elongated condensing tank 2 has less heat insulation measures than other parts, the temperature decreases due to natural heat radiation to the outside, and the heat medium vapor in the condensing tank 2 is cooled and condensed. The pressure decreases, and the heat medium vapor in the vertical closed container 1 is sucked into the horizontal condensing tank 2.
又パイプ２０の内部に狭搾部２１が形成してあるので、
熱媒蒸気は狭搾部２１の小さな断面積の通路を通るため
、第４図に示すようにこの部分の速度がベクトルＶに示
す如く大きくなる。Also, since the narrowed portion 21 is formed inside the pipe 20,
Since the heat medium vapor passes through a passage having a small cross-sectional area in the narrowed portion 21, the velocity in this portion increases as shown by vector V as shown in FIG.
したがって竪長密閉容器１の上方の熱媒蒸気は上記の急
速な流れに誘導され、点線で示した流線Ｓに沿つて流れ
、一ヵ所に滞溜することがない。Therefore, the heat medium vapor above the vertical closed container 1 is guided by the above-mentioned rapid flow, flows along the streamline S shown by the dotted line, and does not accumulate in one place.
そのため竪長密閉容器１の内部上方に滞溜し易い低沸点
物質は横長凝縮槽２内に誘導され、低沸点物質と熱媒液
とは凝縮温度差によって分離せしめられるのである。Therefore, the low boiling point substance that tends to accumulate in the upper part of the vertical closed container 1 is guided into the horizontally long condensing tank 2, and the low boiling point substance and the heat transfer liquid are separated by the condensation temperature difference.
液化した熱媒液を該凝縮槽２と、前記熱媒液容器３とを
連通させた戻しパイプ２２で、横長熱媒液容器３内に戻
すのである。The liquefied heat medium liquid is returned into the horizontally elongated heat medium liquid container 3 through a return pipe 22 that communicates the condensation tank 2 with the heat medium liquid container 3.
なお２３は低沸点物質の不純物ガスの排出パイプであり
、常時はその先端を封断２４してある。Note that 23 is a discharge pipe for discharging impurity gas of a low boiling point substance, and its tip 24 is normally sealed off.
この発明は上記のように構成されているので前記従来技
術の問題点を解決することができる。Since the present invention is configured as described above, it is possible to solve the problems of the prior art.
即ち、電熱ヒータ４に面接触している薄膜状熱媒液５は
高い熱伝導作用で加熱され、該熱媒液５を、対流作用に
よって循環させることなく直ちに蒸発させるので、従来
の同種装置より蒸発が短時間に行われる。That is, the thin film heat medium liquid 5 that is in surface contact with the electric heater 4 is heated by a high heat conduction effect, and the heat medium liquid 5 is immediately evaporated without being circulated by convection. Evaporation takes place in a short time.
そして又、蒸発した熱媒蒸気は少量づつ直ちに蒸気室９
に移行するので、突沸現象は防止される。Then, the evaporated heat medium vapor is immediately released into the steam chamber 9 little by little.
Therefore, the bumping phenomenon is prevented.
このため突沸現象によって液滴の飛散による熱交換面の
温度ならを防止できる。Therefore, it is possible to prevent the temperature of the heat exchange surface from fluctuating due to the scattering of droplets due to the bumping phenomenon.
更に電熱ヒータ４の上部は自由表面上に露出しているの
で、熱媒容器内の熱媒液が極めて少量でよい。Furthermore, since the upper part of the electric heater 4 is exposed on the free surface, only a very small amount of heat medium liquid is required in the heat medium container.
又横長凝縮槽２の自然放熱で該槽内の熱媒蒸気は冷却さ
れて凝縮し、蒸気圧が低くなり、凝縮槽２に吸引作用を
生じせしめ、特に狭搾部２１による急速な流れによって
竪長密閉容器１内の上部に滞溜し易い低沸点物質を、横
長凝縮槽２内に誘導できるので、前記低沸点物質による
、竪長密閉容器１内の上下の温度むらはなくなるのであ
る。Also, due to the natural heat dissipation of the horizontally elongated condensing tank 2, the heat medium vapor in the tank is cooled and condensed, the vapor pressure becomes low, and a suction effect is produced in the condensing tank 2. In particular, the rapid flow from the narrowed part 21 causes the vertical Since the low boiling point substances that tend to accumulate in the upper part of the long sealed container 1 can be guided into the horizontally long condensing tank 2, the temperature unevenness in the vertical closed container 1 caused by the low boiling point substances can be eliminated.
