Abstract
Description
(1)精製装置の構成
図1は、本発明の第1の実施形態に係る有機材料の精製装置1の概略的な水平断面図である。精製装置1は、内筒体2と、外筒体3と、温度調整システム4と、真空ポンプ5と、湾曲板6とを含む。以下、精製装置1の各部の構成についてさらに説明する。
引き続き図1を参照して、本実施形態に係る精製装置1の動作について説明する。有機材料Mの精製工程では、まず外筒体3の内部に内筒体2を封入する。具体的には、蓋体31,32の少なくともいずれかを取り外した状態で、外筒体3の開放された端部から内筒体2を内部に挿入する。その後、蓋体31,32を取り付けて、外筒体3を密封する。有機材料Mは、このときまでに内筒体2の気化区間21に配置される。また、湾曲板6も、このときまでに内筒体2の捕集区間22に配置される。
図2は、図1に示された精製装置1のI-I線断面図である。なお、図1においてI-I線は内筒体2の捕集区間22Bに図示されているが、本実施形態において内筒体2および湾曲板6の形状は捕集区間22A,22B,22Cを通じて同様であるため、以下の説明では内筒体2(捕集区間22)および湾曲板6の符号を使用する。また、図2以降の断面図において、ヒータ41,42および温度センサ43は図示を省略されている。
図4は、本発明の第2の実施形態に係る有機材料の精製装置1Eの断面図である。図示されているように、本実施形態では、内筒体2の内側における湾曲板6Eの配置が、上記の第1の実施形態とは異なる。それ以外の点について、本実施形態の構成は上記の第1の実施形態と同様であるため、重複した説明は省略する。
図5は、本発明の第3の実施形態に係る有機材料の精製装置1Fの断面図である。図示されているように、本実施形態では、内筒体2の内側に、第1の実施形態の湾曲板6に代えて折曲板6Fが配置される。それ以外の点について、本実施形態の構成は上記の第1の実施形態と同様であるため、重複した説明は省略する。
図6Aから図6Fは、本発明の他の実施形態に係る有機材料の精製装置の内筒体2および板部材の断面図である。これらの図において示される折曲板61G,62Gおよび湾曲板61H,62Hも、筒体の内側に配置され筒体の長さ方向に延びる板部材の例である。なお、図6Aから図6Fでは外筒体3、および外筒体3の外側に配置される部材の図示を省略している。
