Description
図1は、本発明によるオゾン製造装置の全体図、図2−aは、本発明の電解セル3の上部から見た詳細図、図2−bは、本発明の電解セル3を横から見た詳細図、図3は、本発明による陽極室枠6及び陰極室枠12の内面に形成した複数の溝13の詳細図を示したものである。
実施例として、図1に示すオゾン水製造装置を使用して電流密度200A/dm2にて電解を行った。図1の3で示すオゾン発生用水電解セルは、図2−a及び図2−bに示すセルを用いた。図2−a及び図2−bの8は、オゾン発生用触媒を導電性多孔体に担持させた陽極、9は、パーフルオロカーボンスルホン酸系イオン交換膜、10は、白金触媒を担持させた陰極である。また6は、陽極室枠、12は、陰極室枠であって、図3に記載の通り複数の溝13を形成したものを使用した。陽極液、陰極液は、それぞれ陽極室1と陽極液の気液分離塔4、陰極室2と陰極液の気液分離塔5の間を循環した。陽極室枠6、陰極室枠12の外側には、冷却ジャケット16,16を設けて、陽極室1及び陰極室2を冷却した。
比較例として、図4に示すように、陽極液のみを陽極室1と陽極液の気液分離塔4の間を循環し、陰極側に循環構造を持たないオゾン水製造装置を用いて電流密度200A/dm2にて電解を行った。この比較例においても、冷却ジャケット16,16を設けて、陽極室1及び陰極室2を冷却した。
実施例、比較例それぞれの結果を表1に示す。これらの結果より、陽極液、陰極液を、それぞれ陽極室1と陽極液の気液分離塔4、陰極室2と陰極液の気液分離塔5の間で循環した方が、陽極液のみを陽極室1と陽極液の気液分離塔4の間で循環した場合よりも、セル全体の温度が低下し、温度分布も小さくなり、高電流効率のオゾンを得ることができた。
