【発明の詳細な説明】
本発明は、加熱による濃縮の際、蒸発器内面に固着し、
または好ましくない分解を起し易い液を迅速に、かつ制
御して加熱蒸発する方法及びその装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention provides that during concentration by heating,
The present invention also relates to a method and apparatus for rapidly and controlledly heating and evaporating a liquid that is prone to undesirable decomposition.
従来の蒸発罐では、水平または垂直管型、薄膜型または
フラッシュ蒸発型のいずれにおいても、溶液は一般に濃
縮につれて粘性が上昇し、移動しにくくなり、最終的に
は固結現象を起すので、これを避けるため、ある程度濃
縮後は、別途の手段例えば噴霧乾燥等を採用して脱水し
固形物を得ている。In conventional evaporation cans, whether horizontal or vertical tube type, thin film type or flash evaporation type, the viscosity of the solution generally increases as it concentrates, making it difficult to move and eventually causing caking. In order to avoid this, after concentrating to some extent, a separate method such as spray drying is used to dehydrate and obtain a solid.
さらに、蒸発罐の内面でスケール状固化物を生成すると
きは、掻取り機構を設けても、過熱されやすいので、特
に熱分解を嫌うような物質の取扱いには不適となる。Furthermore, when a scale-like solidified substance is generated on the inner surface of the evaporation can, even if a scraping mechanism is provided, it is easily overheated, making it particularly unsuitable for handling substances that do not like thermal decomposition.
本発明の骨子は溶液の加熱蒸発における上記の困難を解
決するため、充分な高温度の加熱面上に、液滴を滴下し
、所定時間だけ加熱面上に滞留させて沸騰蒸発を行わせ
た後そこから離脱させるもので、以下図面につき本発明
の詳細な説明する。The gist of the present invention is to solve the above-mentioned difficulties in heating and evaporating solutions by dropping droplets onto a heating surface at a sufficiently high temperature and allowing them to remain on the heating surface for a predetermined period of time to cause boiling and evaporation. The invention will now be described in detail with reference to the drawings.
図において、１は横型円筒状の外殻容器で、この中に表
面に軸方向の凹み又は、溝２′を設けた円筒状横型回転
体２が、外殻装置の端部を貫き、シールされた状態下、
摺動的回転できるように納められる。In the figure, 1 is a horizontal cylindrical outer shell container, in which a cylindrical horizontal rotating body 2 having an axial recess or groove 2' on its surface penetrates the end of the outer shell device and is sealed. Under the condition,
It is housed for sliding rotation.
回転体の内部には電熱線や加熱用熱媒体３を導入する。A heating wire or a heating medium 3 is introduced into the rotating body.
この回転体の上面の凹み又は溝２′に、蒸発加熱しよう
とする液を液滴としてノズル４から供給する。The liquid to be evaporated and heated is supplied from the nozzle 4 as droplets to the recess or groove 2' on the upper surface of the rotating body.
液滴は、円筒体の回転速度に依存する時間たけ溝上に滞
留してから外殻容器１の底へと落下する。The droplets remain on the groove for a time that depends on the rotational speed of the cylinder and then fall to the bottom of the shell container 1.
この間に蒸発して固化すれば、固化物は適蟲な移動手段
によりストッパー口５を経由してホッパー６に集められ
、発生した蒸気は、排気ロアから排出する。If it evaporates and solidifies during this time, the solidified material is collected in the hopper 6 via the stopper port 5 by an appropriate moving means, and the generated steam is discharged from the exhaust lower.
本発明の実施例として、ＭｇＯ／Ｍｇ■２モル比３にな
るようにＭｇＯ粉末を混合したヨウ化マグネシウム水溶
液（濃度５０％）の加熱蒸発について説明する。As an example of the present invention, heating evaporation of a magnesium iodide aqueous solution (concentration 50%) in which MgO powder is mixed so that the MgO/Mg2 molar ratio is 3 will be described.
この物質を、蒸発容器（ガラス製）で加熱すると次第に
粘稠化し最終的には極めて固い固形物を生成して容器か
ら取出し難いものである。When this substance is heated in an evaporation container (made of glass), it gradually becomes viscous and eventually forms an extremely hard solid that is difficult to remove from the container.
そこで図と同じ装置（縮尺１１５）を用いて実験を行っ
た。Therefore, an experiment was conducted using the same apparatus (scale 115) as shown in the figure.
外殻容器１は耐熱ガラス製、回転体２は黒鉛製のもので
、電熱加熱下、回転体の表面温度を４７０℃に保ちなが
ら、スラリー液滴を回転体の凹み又は溝に滴下したとこ
ろ、液滴は速かに沸騰して転動し、液滴の大きさが夫々
１個当り０．２Ｓ’及び０．６ｙの時、滞留時間３秒及
び１４秒間で遊離水が蒸発し終ることを認めた。The outer shell container 1 was made of heat-resistant glass, and the rotating body 2 was made of graphite. Slurry droplets were dropped into the recesses or grooves of the rotating body under electric heating while maintaining the surface temperature of the rotating body at 470°C. The droplets boil and roll rapidly, and when the droplet sizes are 0.2 S' and 0.6 y per droplet, the free water is completely evaporated after residence times of 3 seconds and 14 seconds, respectively. Admitted.
落下して得られた顆粒は３Ｍｇ（ＯＨ）２ＭｇＩ２の組
成を示した。The granules obtained by falling showed a composition of 3Mg(OH)2MgI2.
表面への液滴の耐着が起らず、操作を連続的に行なうこ
とができた。Droplets did not stick to the surface, and the operation could be performed continuously.
なお、この物質は、４７０°Ｃの温度下、回転速度を遅
くして長時間滞留させると、分解が進み、ヨウ化水素と
水蒸気を発生して固形物として酸化マグネシウムを残す
傾向を示した。It should be noted that when this substance was allowed to remain for a long time at a temperature of 470°C with a slow rotational speed, it tended to decompose, generate hydrogen iodide and water vapor, and leave magnesium oxide as a solid.
