- 誘導加熱により内部に投入された廃アスベストを溶融させる誘導加熱炉と、
排気管を通じて前記誘導加熱炉の内部雰囲気を吸引して該誘導加熱炉の内部を負圧に調整する吸引手段と
を備えた廃アスベスト無害化装置において、
前記排気管には、大気導入口に連通し、かつ該大気導入口より導入された空気の通過を許容、あるいは規制する調整バルブが配設された複数の大気導入配管がそれぞれ連設されており、
前記誘導加熱炉の内部の圧力を検知する炉圧検知手段と、
常態においては前記調整バルブをそれぞれ開成させる一方、前記炉圧検知手段により検知された圧力値が予め決められた設定上限値を超える場合には、開成している前記調整バルブの少なくとも一つを閉成させる制御手段と
を備えたことを特徴とする廃アスベスト無害化装置。 - 前記制御手段は、前記炉圧検知手段により検知された圧力値が、予め決められ、かつ前記設定上限値よりも小さい設定下限値未満となる場合であって既に閉成させた調整バルブがあるときには、該調整バルブを開成させることを特徴とする請求項1に記載の廃アスベスト無害化装置。
