Claims (3)
- 重金属安定化剤の供給槽から飛灰混錬機への重金属安定化剤の注入配管に沈殿分離器を付加するものであり、沈殿分離器は上フランジと下フランジで閉塞される密閉体であるケーシングで、ポンプからの注入管である流入部は前記上フランジを貫通して下向きに設けられ、この流入部を取り囲むように穴を上下に複数設けた管体を前記上フランジと下フランジ間で前記ケーシングの内部を仕切るように上下方向に設置し、この管体を設けない場合に比較して流速を弱めることで沈殿分離器で凝固物を沈殿させることを特徴とする飛灰混錬機への重金属固定剤注入装置。
- 上下に複数設ける穴は、上のものから下のものへと縮径する請求項1記載の飛灰混錬機への重金属固定剤注入装置。
- 飛灰混錬機への重金属安定化剤の注入配管で、沈殿分離器からの注入配管は水平に左右に並んで左右のものを同じ高さになるようにした請求項1または請求項2記載の飛灰混錬機への重金属固定剤注入装置。
