Claims (11)
- 使用済み紙おむつの発酵処理に伴って発生する臭気ガスの脱臭処理方法であって、前記臭気ガスを熱交換によって昇温させた後、200〜300℃で金属系触媒を用いた触媒脱臭処理を行い、次いで該脱臭処理された処理ガスを前記熱交換用の熱源とし、更に該熱交換後の処理ガスを発酵処理に供給する酸素含有ガスと熱交換してから大気に放出することを特徴とする脱臭処理方法。
- 前記発酵処理後の固形残渣と該固形残渣と共に排出される臭気ガスとを集塵機で回収・分離し、分離された臭気ガスを熱交換によって昇温させた後、200〜300℃で金属系触媒を用いた触媒脱臭処理を行い、次いで該脱臭処理された処理ガスを前記熱交換用の熱源とし、更に該熱交換後の処理ガスを発酵処理に供給する酸素含有ガスと熱交換してから大気に放出する請求項1に記載の脱臭処理方法。
- 前記金属系触媒は、アルミニウム、カルシウム、チタン、ケイ素、ジルコニウムおよびセリウムよりなる群から選択される1種以上の元素の酸化物を担体とし、該担体に、金、銀、白金、パラジウム、イリジウム、ロジウム、オスミウム、ルテニウム、ニッケル、コバルト、クロム、マンガンおよび銅よりなる群から選択される1種以上の金属元素を担持させたものである請求項1または2に記載の脱臭処理方法。
- 前記臭気ガスを熱交換した後、更に加熱してから脱臭処理する請求項1〜3のいずれかに記載の脱臭処理方法。
- 前記酸素含有ガスと熱交換した後の処理ガスを誘引することによって、発酵処理及び触媒脱臭処理を陰圧状態で行なう請求項1〜4のいずれかに記載の脱臭処理方法。
- 使用済み紙おむつを発酵処理した際に発酵処理槽内で発生する臭気ガスの脱臭処理装置であって、少なくとも前記臭気ガスを脱臭する金属系触媒を用いた触媒脱臭装置、前記臭気ガスと脱臭処理して得られた処理ガスを熱交換するための第1熱交換器、第1熱交換器から排出された処理ガスと発酵処理に供給する酸素含有ガスを熱交換する第2熱交換器を備えていることを特徴とする脱臭処理装置。
- 前記発酵処理後の固形残渣と該固形残渣と共に排出される臭気ガスとを回収・分離するための集塵機と、該集塵機で分離された臭気ガスを前記脱臭装置へ導入するラインが併設されており、かつ前記発酵処理槽内で発生した臭気ガスの脱臭処理と該集塵機で分離された臭気ガスの脱臭処理を交互に繰り返す切換手段を有している請求項6に記載の脱臭処理装置。
- 前記金属系触媒は、アルミニウム、カルシウム、チタン、ケイ素、ジルコニウムおよびセリウムよりなる群から選択される1種以上の元素の酸化物を担体とし、該担体に、金、銀、白金、パラジウム、イリジウム、ロジウム、オスミウム、ルテニウム、ニッケル、コバルト、クロム、マンガンおよび銅よりなる群から選択される1種以上の金属元素を担持させたものである請求項6または7に記載の脱臭処理装置。
- 前記第1熱交換器と脱臭装置の間に、前記第1熱交換器で昇温された臭気ガスを加熱するための加熱手段が設けられている請求項6〜8のいずれかに記載の脱臭処理装置。
- 前記第2熱交換器で昇温された酸素含有ガスを加熱するための加熱手段が設けられている請求項6〜9のいずれかに記載の脱臭処理装置。
