Description
1)汚染物質を発生しない超臨界二酸化炭素ドライクリーニング装置
2)洗浄剤として、合成化学物質を一切使用しないドライクリーニングの確立
3)洗浄助剤を一切使用しない洗浄
4)衣類に残留する化学物質を極力除去できる洗浄
5)アレルギーの原因物質あるいはアレルギーを悪化させる原因物質となる、カビ、化 学物質の除去、細菌類の滅菌ができる洗浄
「初期設定」:凝縮器、液溜槽、吐出器へCO2(二酸化炭素の略記)を供給 する。
「被洗浄物充填」:洗浄槽へ被洗浄物を入れ密閉する。洗浄槽へ液溜槽からCO2 を流し込み、空気を排除するとともに洗浄槽へCO2を充填す る。
「洗浄槽へ吐出開始」:吐出器1のCO2を高速加熱昇圧し、設定圧10MPaになると 自動的に超臨界状態のCO2が洗浄槽へ吐出を開始する。
「吐出継続」:吐出器1の圧力を10MPaに保持するように過熱して吐出を継 続する。洗浄槽を出たCO2は蒸発器へ断熱膨張して排出され 凝縮器を経て液溜槽に溜まる。
「吐出器1の吐出終了」:吐出器1から10分間吐出継続後加熱を停止し吐出を終了する。「吐出器2から洗浄槽 へ吐出開始」:吐出器2のCO2を高速加膨張させることにより、設定圧10M Paになると自動的に超臨界状態のCO2が洗浄槽へ継続吐出 される。
「吐出継続」:吐出器2の圧力を10MPaに保持して吐出を継続する。
「吐出器2の吐出終了」:吐出器2から10分間吐出継続後加熱を停止し吐出を終了する。 この間、液溜槽から吐出器1へCO2が供給される。
「吐出器1から洗浄槽
へ吐出開始、継続」:吐出器2から吐出器1へ切り換える。超臨界状態のCO2が洗 浄槽へ継続吐出され、洗浄槽圧は10MPaに継続保持される。「吐出器1の吐出終了」:吐出器1から10分間吐出継続後加熱を停止し吐出を終了し、 洗浄が終了する。洗浄槽の低圧CO2を低圧回収槽へ回収。
「被洗浄物の取り出し」:洗浄槽残留CO2を排出し大気圧とする。
「洗浄終了」:被洗浄物を洗浄槽から取り出す。
Claims (6)
- 洗浄剤の二酸化炭素を超臨界状態にする加熱機構を具備し、超臨界状態にした二酸化炭素を加熱により圧力差を誘起し駆動力として洗浄槽へ吐出噴射する少なくとも1個の吐出器と、被洗浄物を充填し超臨界状態で洗浄する洗浄槽と、洗浄後に液体状態にした二酸化炭素を加熱蒸発し汚れ成分を分離除去する蒸発器と、蒸発器でガス化した二酸化炭素を液化する凝縮器と、液状に凝縮した二酸化炭素を溜めて随時吐出器へ二酸化炭素を供給する液溜槽とからなる衣類、寝具、毛皮等洗濯対象物を洗浄するドライクリーニング装置。
