Description

本発明は、グラスライニング製反応缶に関し、特に、熱伝達を向上させることにより、金属製缶体内の液体との熱交換効率を向上させるための新規な改良に関する。   The present invention relates to a glass-lined reaction can, and more particularly to a novel improvement for improving heat exchange efficiency with a liquid in a metal can by improving heat transfer.

従来、用いられていたこの種のグラスライニング製反応缶としては、社内製作のみで特許出願を行っていないため、特許文献等は開示していないが、その構成を図4に開示することができる。
すなわち、図4において、符号1で示されるものは、全体が密閉型の缶状をなす金属製缶体であり、この金属製缶体1の上部にはモータ2を有する減速機架台3が設けられ、この金属製缶体1内に回転自在に設けられた攪拌羽根4の軸5は前記減速機架台3を介して前記モータ2に接続されている。
Conventionally, this kind of glass-lined reaction can, which has been used in-house, has not been applied for a patent, and thus no patent document is disclosed, but its configuration can be disclosed in FIG. .
That is, in FIG. 4, what is denoted by reference numeral 1 is a metal can body that forms a sealed can as a whole, and a reduction gear base 3 having a motor 2 is provided on the top of the metal can body 1. A shaft 5 of a stirring blade 4 provided and rotatably provided in the metal can 1 is connected to the motor 2 via the speed reducer base 3.

前記金属製缶体1の缶体外表面6には、この缶体外表面6の側部を覆うと共に所定の間隔の空洞からなるジャケット7が形成され、このジャケット7の複数個所には、このジャケット7内に冷却又は加熱用の液体又は気体等からなる媒体を供給して排出する循環用の入口8及び出口9が設けられている。   A jacket 7 is formed on the outer surface 6 of the metal can body 1 so as to cover the side of the outer surface 6 of the can body and to be formed with cavities having a predetermined interval. A circulation inlet 8 and outlet 9 for supplying and discharging a medium made of a liquid or gas for cooling or heating are provided therein.

前記金属製缶体1の上部に形成されたノズル10には、このノズル10を貫通する状態で下部に感温部11aを有するバッフル11が挿入され、このバッフル11は、前記金属製缶体1の内部に吊り下げられた状態で保持されると共に金属製缶体1内の加熱又は冷却される液体と接触することができるように構成されている。   A baffle 11 having a temperature sensing portion 11a in the lower part is inserted into the nozzle 10 formed in the upper part of the metal can body 1 so as to penetrate the nozzle 10, and the baffle 11 is connected to the metal can body 1. It is comprised so that it can be contacted with the liquid in the metal can body 1 being heated or cooled while being held in a suspended state.

前記ジャケット7には、エアー抜き12、脚13、ドレン口14、アジテーティングノズル15が設けられ、前記金属製缶体1には、覗窓16、マンホール17、フラッシュバルブ18が設けられている。   The jacket 7 is provided with an air vent 12, a leg 13, a drain port 14, and an agitating nozzle 15, and the metal can 1 is provided with a viewing window 16, a manhole 17, and a flash valve 18. .

従って、前述の構成において、前記金属製缶体1内に医薬品等の液体を供給し、前記ジャケット7内に供給する媒体と同じ媒体をバッフル11内に供給してノズル10を密閉した後に、モータ2により攪拌羽根4を攪拌しつつ、前記バッフル11及びジャケット7内の媒体によって熱交換が行われ、前記液体の冷却又は加熱が行われる。   Therefore, in the above-described configuration, a liquid such as a medicine is supplied into the metal can 1, the same medium as the medium supplied into the jacket 7 is supplied into the baffle 11, and the nozzle 10 is sealed. While the stirring blade 4 is being stirred by 2, heat exchange is performed by the medium in the baffle 11 and the jacket 7, and the liquid is cooled or heated.

従来のグラスライニング製反応缶は、以上のように構成されていたため、次のような課題が存在していた。
すなわち、グラスライニングは、鉄等の金属製母材に無機ガラスを高温で焼付けたもので、ガラスの表面を持つことから洗浄性に優れ、また、理化学ガラスと同等又はそれ以上の耐薬品性や耐熱性を有することから、化学薬品用の反応容器や医薬品の製造釜等に幅広く使用されている。
一般に、グラスライニングは金属製母材上に下釉を掛けて焼成し、更に上釉を掛けて焼成することにより形成されている。
しかしながら、ライニングされるガラスの熱伝導率λgが1.0(Kcal/m.h.℃)と炭素鋼の熱伝導率λFe45(Kcal/m.h.℃)に比べて1/45と小さく、ジャケット側から加熱・冷却での液体の内容物への熱伝導が小さく、総括伝熱係数U値が加熱時でジャケット内の流体がスチームである場合、該缶体内の液体が有機液体で300〜400(Kcal/m.h.℃)である。
Since the conventional glass-lined reaction can was configured as described above, the following problems existed.
In other words, glass lining is made by baking inorganic glass on a metal base material such as iron at a high temperature, and has excellent cleaning properties because it has a glass surface, and has chemical resistance equivalent to or higher than that of physics and chemistry glass. Because it has heat resistance, it is widely used in reaction vessels for chemicals and pharmaceutical manufacturing pots.
In general, the glass lining is formed by firing on a metal base material with a lower iron and then firing with an upper iron.
However, the thermal conductivity λg of the lining glass is 1.0 (Kcal / mh ° C), which is 1/45 smaller than the thermal conductivity λFe45 (Kcal / mh ° C) of carbon steel. When the heat conduction to the contents of the liquid is small, the overall heat transfer coefficient U value is heating, and the fluid in the jacket is steam, the liquid in the can is an organic liquid of 300 to 400 (Kcal / mh ° C. ).

従って、固体と流体との間に温度差があると、両者の間に伝導ならびに対流による熱交換が行われる。
このときの伝熱速度Q(Kcal/h)は通常、伝熱面積A(m2)に比例し、また流体の平均温度t(℃)と壁温tw(℃)との差に比例するので次式で表される。
Q=xA(t−tw)
比例定数x(Kcal/m2.h.℃)は境膜伝熱係数と呼ばれ、その値は両端の流れの状態によって異なる。
Therefore, if there is a temperature difference between the solid and the fluid, heat exchange by conduction and convection occurs between the two.
At this time, the heat transfer rate Q (Kcal / h) is usually proportional to the heat transfer area A (m 2 ) and also proportional to the difference between the average fluid temperature t (° C.) and the wall temperature tw (° C.). It is expressed by the following formula.
Q = xA (t−tw)
The proportionality constant x (Kcal / m 2 · h · ° C.) is called a film heat transfer coefficient, and its value varies depending on the flow conditions at both ends.

グラスライニング装置のように固体壁をはさんで温度の異なる流体の間で熱移動が行われる場合には、高温流体の平均温度tと低温流体の平均温度tとの差を温度の推進力としてとると、高温流体から低温流体への伝熱速度は
Q=U11(t−t
で表される。
係数Uを総括伝熱係数と呼び、
数1の(1)式で表される。
When the heat transfer is performed between the different fluid temperature across the solid wall as glass lining apparatus, promoting the temperature difference between the average temperature t 2 of the average temperature t 1 and the low temperature fluid high temperature fluid As a force, the heat transfer rate from the hot fluid to the cold fluid is
Q = U 1 A 1 (t 1 -t 2 )
It is represented by
Called coefficients U 1 and overall heat transfer coefficient,
It is expressed by Equation (1) in Equation 1.

前記U値を向上させるためには、
(1)Ig:グラスライニング厚みを薄くする。
(2)Kg:グラスの熱伝導度を高くする。
ことの二点が重要であるが、グラスライニングのガラスライニング厚は、JIS−R4201規格に0.6〜2.5mmと定められているが、実際のグラスライニング装置のガラスライニング厚はピンホール発生・修正・手直し焼成を焼成途中で繰り返し、通常2000L容器で1.3〜2.0mm位で製品化されている。
釉薬のくすり掛けは1回当たり0.2〜0.3mm位で、下釉施工を1〜2回、上釉施工を4〜5回行い、その都度、焼成炉内で溶融・焼付けをしている。
In order to improve the U value,
(1) Ig: Reduce the thickness of the glass lining.
(2) Kg: Increase the thermal conductivity of the glass.
Two points are important, but the glass lining thickness of the glass lining is defined as 0.6 to 2.5 mm in the JIS-R4201 standard, but the glass lining thickness of the actual glass lining device is a pinhole.・ Correction and reworking firing is repeated in the middle of firing, and is usually commercialized in a 2000-L container at about 1.3 to 2.0 mm.
The glaze is applied at a rate of about 0.2 to 0.3 mm per time, the lower iron is applied 1-2 times, and the upper iron is applied 4-5 times, each time being melted and baked in a firing furnace. Yes.

グラスライニング装置の総括伝熱係数U値を向上させるためには、ガラスライニングの下釉厚み+上釉厚みの総計厚みを外側ジャケットに対応する該缶体内部のガラスライニング厚みで0.6〜1.2mmの薄膜にすることが必要である。   In order to improve the overall heat transfer coefficient U value of the glass lining apparatus, the total thickness of the lower lining thickness of the glass lining + the upper heel thickness is 0.6 to 1 in terms of the glass lining thickness inside the can corresponding to the outer jacket. It is necessary to make a thin film of 2 mm.

本発明によるグラスライニング製反応缶は、内面にグラスライニングが形成された金属製缶体と、前記金属製缶体内に設けられモータ駆動により回転する攪拌羽根と、前記金属製缶体の外周に設けられ前記金属製缶体内の液体を加熱又は冷却させるための媒体を収容するジャケットからなるグラスライニング製反応缶において、前記グラスライニングは、総厚さが0.6〜1.2mmであり、総括伝熱係数(U値:Kcal/m.hr.℃)を加熱時でジャケット内の流体がスチームで、前記金属製缶体内の流体が有機液体の時の前記U値370〜800(Kcal/m2.hr.℃)にした構成であり、また、前記金属製缶体の前記ジャケットに対応する缶体外表面には、鉄金属より熱伝導度が大であるアルミニウム、銅、金、銀、亜鉛の何れかをコーティングした構成であり、また、前記缶体外表面には、凹凸面が形成されている構成であり、また、前記缶体外表面には、スパイラル形状の帯板又はディンプル形状の金属チップが溶接密着されている構成であり、また、前記金属製缶体の内側部には、少なくとも一対の接続管を介し前記流体に接する状態でバッフルが設けられ、前記ジャケットと前記バッフルとの間は前記各接続管を介して連通し、前記ジャケット内の前記媒体が前記バッフル内を循環する構成である。 A glass-lined reaction can according to the present invention is provided on a metal can body having a glass lining formed on an inner surface, a stirring blade provided in the metal can body and rotated by a motor, and provided on an outer periphery of the metal can body. In the glass-lined reaction can comprising a jacket containing a medium for heating or cooling the liquid in the metal can, the glass lining has a total thickness of 0.6 to 1.2 mm. When the heat coefficient (U value: Kcal / m 2 .hr. ° C.) is heated, the fluid in the jacket is steam, and the U value is 370 to 800 (Kcal / m) when the fluid in the metal can is an organic liquid. 2 hr. ° C.), and the outer surface of the can body corresponding to the jacket of the metal can body is made of aluminum, copper, gold, silver, zinc, which has higher thermal conductivity than iron metal. Configuration coated with either In addition, an uneven surface is formed on the outer surface of the can body, and a spiral band plate or a dimple-shaped metal tip is welded and adhered to the outer surface of the can body. In addition, a baffle is provided in an inner portion of the metal can body so as to be in contact with the fluid via at least a pair of connection pipes, and the jacket and the baffle communicate with each other via the connection pipes. The medium in the jacket circulates in the baffle.

尚、従来例と同一又は同等部分については、同一符号を付して説明する。
図1において符号1で示されるものは、全体が密閉型の缶状をなす金属製缶体であり、この金属製缶体1の上部にはモータ2を有する減速機架台3が設けられ、この金属製缶体1内に回転自在に設けられた攪拌羽根4の軸5は前記減速機架台3を介して前記モータ2に接続されている。

A shaft 5 of a stirring blade 4 rotatably provided in the metal can 1 is connected to the motor 2 via the reduction gear base 3.

前記金属製缶体1の缶体外表面6には、この缶体外表面6の側部を覆うと共に所定の間隔の空洞からなるジャケット7が形成され、このジャケット7の複数個所には、このジャケット7内に冷却又は加熱用の液体又は気体等からなる媒体を供給して排出する循環用の入口8及び出口9が設けられている。   A jacket 7 is formed on the outer surface 6 of the metal can body 1 so as to cover the side of the outer surface 6 of the can body and to be formed with cavities having a predetermined interval. A circulation inlet 8 and outlet 9 for supplying and discharging a medium made of a liquid or gas for cooling or heating are provided therein.

前記金属製缶体1の上部に形成されたノズル10には、このノズル10を貫通する状態でバッフル11が挿入され、このバッフル11は、金属製缶体1の内側部1aに設けられた少なくとも一対の接続管20により前記金属製缶体1内に内設されている。   A baffle 11 is inserted into the nozzle 10 formed in the upper part of the metal can body 1 so as to penetrate the nozzle 10, and the baffle 11 is provided at least on the inner portion 1 a of the metal can body 1. A pair of connecting pipes 20 are installed inside the metal can body 1.

前記ジャケット7とバッフル11との間を接続する接続管20により、このジャケット7とバッフル11との間が連通され、ジャケット7内を循環する冷却又は加熱用の媒体は、図示しない媒体供給源によって入口8から出口9を介して循環し、この媒体も前記バッフル11を循環するように構成されている。尚、この入口8及び出口9は、水蒸気の場合に、入口8から入れて出口9からドレンとして排出するが、媒体が水蒸気以外の熱媒体あるいは冷却水、ブラインなどの液体により金属製缶体1を加熱あるいは冷却する場合は、点線の矢印で示されるように、符号15aで示されるアジテーティングノズル又は出口9が液体の入口となり、前記入口8が出口となる。   The jacket 7 and the baffle 11 are communicated with each other by a connecting pipe 20 connecting the jacket 7 and the baffle 11, and a cooling or heating medium circulating in the jacket 7 is supplied by a medium supply source (not shown). The medium is circulated from the inlet 8 through the outlet 9, and this medium is also circulated through the baffle 11. In the case of water vapor, the inlet 8 and the outlet 9 are inserted from the inlet 8 and discharged from the outlet 9 as a drain. However, the metal can 1 is made of a heat medium other than water vapor or a liquid such as cooling water or brine. In the case of heating or cooling the liquid, the agitating nozzle or outlet 9 indicated by reference numeral 15a serves as the liquid inlet and the inlet 8 serves as the outlet, as indicated by the dotted arrow.

前記ジャケット7には、エアー抜き12、脚13、ドレン口14、アジテーティングノズル15aが設けられ、前記金属製缶体1には、覗窓16、マンホール17、フラッシュバルブ18が設けられている。   The jacket 7 is provided with an air vent 12, a leg 13, a drain port 14, and an agitating nozzle 15 a, and the metal can 1 is provided with a viewing window 16, a manhole 17, and a flash valve 18. .

Therefore, by repeating the firing of the lower layer, it is possible to withstand the actual firing load even at this thin thickness. Further, at least one of SiO 2 , Al 2 O 3 , AlN, C, and SiC is added to the lower brazing layer by milling at 1 to 90 W% with respect to 100 W% of the frit, thereby providing fire resistance and thermal conductivity.

また、前記缶体外表面6には、図示していないが、凹凸面の形成、スパイラル形状の帯体、ディンプル形状の金属チップの溶接により、前記缶体外表面6の表面積を増大させて熱交換効率を向上させることができる。   Further, although not shown in the figure, the outer surface 6 of the can body is increased in heat exchange efficiency by increasing the surface area of the outer surface 6 of the can body 6 by forming an uneven surface, welding a spiral strip, and a dimple metal tip. Can be improved.
