Abstract
【解決手段】空気圧縮機の前段側に、水噴霧装置を具備した噴霧室を配設してなる酸素製造設備およびそれを用いた酸素製造方法。
【選択図】図2
Description
このような酸素製造設備では、沸点差を利用して、空気を分離することで、酸素を製造する。その際、窒素、アルゴンなどが副産物として得られる。
従来の酸素製造設備においては、気温が上昇した場合、気温に応じて空気圧縮機で圧縮する原料の空気密度が低下することから、得られる酸素量が少なくなることが知られている。このため、気温が高い夏場では、製鋼工場などを含めた所内酸素使用量の調整(削減)を行うことによって、酸素製造設備と、所内酸素使用量との需給バランスを保っていた。
なお、図3に示すような装置を用いて酸素を製造する際には、電気は、主に空気圧縮機3の電動モータで消費されている。
すなわちこの装置で酸素を製造する際、空気圧縮機3は、大気から取り込んだ空気を圧縮し所定の圧力(例えば、0.54MPa)まで昇圧する必要があるところ、水洗塔4内で圧損が大きいので、空気圧縮機の電動モータ出力を上げて運転しなければならず、逆に電力消費量の増大につながる恐れのある酸素製造設備であった。
1.大気中の空気を空気圧縮機で圧縮し、沸点差を利用して、空気を分離することで、酸素を製造する酸素製造設備において、前記空気圧縮機の前段側に、水噴霧装置を具備した噴霧室を配設してなることを特徴とする酸素製造設備。
また水噴霧装置を具備した噴霧室内では、圧損がほとんど生じないことから、省電力型酸素製造設備を実現できる。
本発明の実施の形態に係る酸素製造設備は、空気圧縮機3の前段側に、水噴霧装置を具備した噴霧室50を配設したことが特徴である。この噴霧室50は、図3に示した水洗塔4に代わり、水噴霧装置としての噴霧ノズル51を具備している。この噴霧室50の上部には、ダクト53を空気圧縮機3と連通させて設ける。また反対側の噴霧室50の下部には、大気と連通させてなる開口を形成する。
なお、噴霧ノズル51は、噴霧水52同士の干渉防止や、噴霧室50壁面への衝突などを勘案し、噴霧室50内で容易に気化させることができるよう、ノズル形式、ノズル数、ノズル配置などを設計するのが好ましい。また、噴霧ノズル51の前段または後段にバグフィルタ2を設ける。図2中、54は、図1に示した酸素製造設備において、酸素を製造する際の空気流を示す。それ以外の装置については、図3に示した従来のものと同一であるので説明を省略する。
この電力削減効果は、図1に示した酸素製造設備において、噴霧ノズルから、水滴の平均粒径が10μm(粒径3〜18μmの範囲)の噴霧水が飽和湿度まで完全に気化蒸発するという条件下で得た。空気圧縮機3の電動モータの軸動力が従来よりも低下する理由は、温度低下による入口の空気密度の増加による。
