Abstract
Description
集塵効率(PM除去効率)=100×(1−Exp(−G×A/Q))
Q:ガス流量
A:有効(集塵)電極面積
G:分離速度(ダストを電極に分離する速度)
図1に示すような構成で、単位電極の枚数を増やしたプラズマ反応器を製造し、これをパルス電源に接続して排気ガス浄化装置として用いて、PMを含有する排気ガスの処理を行い、PM除去率を測定した。
実施例1と同様にして排気ガス浄化装置を作製した。パルス電圧の印加条件を、パルス幅を4.7μsec、電界強度を35.2kV/cm、エネルギー投入量を被処理物質に対して1.78J/μgとした以外は、実施例1の場合と同様にして排気ガス処理試験を行い、PM除去率の測定を行った。結果を表1に示す。また、印加したパルス電圧の波形を図5に示す。図5において、波形32が実施例2の排ガス浄化装置についてのパルス電圧の波形である。
実施例1の場合と同様にしてプラズマ反応器を作製し、パルス電源としては短いパルス幅の電圧を印加する高電圧パルス電源を使用して、排気ガス浄化装置を作製した。この排気ガス浄化装置を使用して、パルス電圧の印加条件を、パルス幅を0.9μs、電界強度を30kV/cm、エネルギー投入量を被処理物質に対して2.0J/μgとした以外は、実施例1の場合と同様にして排気ガス処理試験を行い、PM除去率の測定を行った。結果を表1に示す。
