Description
本実施形態で用いる研削装置の概略構成を図1に、その要部断面を図2にそれぞれ示す。
本実施形態で用いる研削装置の要部断面を図3に、その被研削部材の横断面を図4にそれぞれ示す。なお、本実施形態は、被研削部材を変更した以外の研削装置の概要は上述した実施形態と同様であり、同一作用を示す部材には、同一符号を付して重複する説明は省略する。
断面外径が150mm×150mmで、長さが860mmであり、目開き6mmで、6mm×6mmの断面矩形の貫通孔を7mmピッチで400有するハニカム型の脱硝触媒1を上述した実施形態1の研削装置に配置し、研削材として#46のアルミナを用い、目標研削量100μmで研削した。この時の脱硝触媒1の前後の差圧は5.4kPaであった。
試験例1と同様な脱硝触媒1の径方向外側に、断面積で10%となるダミーセル2を均一に配置したものを被研削部材とし、規制部材25を外した以外は、実施形態2と同様な研削装置で、試験例1と同様な試験を行った。

Claims (4)
- 脱硝触媒からなる被研削部材の一端部に、当該被研削部材の断面積より大きな断面積の拡開部を具備する上流固定部材を連結する一方、前記被研削部材の他端部に、当該被研削部材との連結側端部から所定寸法だけ一定断面積の流路を具備する下流固定部材を連結し、
前記上流固定部材の上流側には、研削材と気体とを混合する混合部を前記拡開部より小さな断面積の流路を有する上流側連結部材で連結すると共に前記拡開部の内方の前記被研削部材側に所定目開きのスクリーン部材を配置し、一方、前記下流固定部材の下流側には前記一定断面積より小さな断面積の下流側連結部材が連結され、当該下流側連結部材の下流側には、前記被研削部材の貫通孔を通過した研削材と当該研削材により研削された被研削物とを分離する分級部と、該分級部を介して前記混合部の気体を吸引する集塵部とを連結し、
前記集塵部による吸引により、前記混合部からの前記気体に混合された研削材を前記上流固定部材に送り、前記拡開部で流速を低下させて前記気体と研削材との混合物を一時的に滞留させた後、当該混合物を前記脱硝触媒の貫通孔及び前記下流固定部材を通過させて当該貫通孔の内壁を研削し、その後、前記分級部を介して前記集塵部で集塵する
ことを特徴とする脱硝触媒の再生方法。 - 請求項1に記載の脱硝触媒の再生方法において、前記下流固定部材の前記分級部側には流路の中央部の流れを規制する規制部材を配置したことを特徴とする脱硝触媒の再生方法。
- 請求項1又は2に記載の脱硝触媒の再生方法において、前記被研削部材は、脱硝触媒の外周にダミーセルを配置したものであることを特徴とする脱硝触媒の再生方法。
- 請求項1〜3の何れか一項に記載の脱硝触媒の再生方法において、前記被研削部材を立設状態で保持して当該被研削部材の下端部を前記上流固定部材で固定すると共に、上端部を前記下流固定部材で固定することを特徴とする脱硝触媒の再生方法。
