Abstract
Description
このように構成された本発明においては、排気ガスの濃度が濃い等の理由により燃焼室の温度が高温になった場合であっても、バイパス通路用制御部により、複数のバイパス通路の一又は複数の開閉弁を開操作して、燃焼室内の排気ガスの一部をバイパス通路へ排出するようにしている。この結果、本発明によれば、燃焼室の破損を防止することができる。さらに、複数のバイパス通路は、それぞれ各蓄熱室の上方側の位置で燃焼室に接続されそれぞれ開閉弁を有するので、各蓄熱体に流入する排気ガスの流量を同じにできるので、シリカの偏った堆積を防止できる。
このように構成された本発明においては、複数のバイパス通路が燃焼室の上部に接続されているので、燃焼室内の排気ガスを、排気ガスの流れに逆らうことなくスムーズにバイパス通路に排出することができる。
このように構成された本発明においては、隣接する蓄熱室の上部側の空間との間の空間に燃焼室内の排気ガスを攪拌する攪拌装置を設けたので、処理される排気ガスの燃焼室内の滞留時間を長くすることができ、これにより、排気ガス成分の分解効率をより高めことができる。
このように構成された本発明においては、供給部及び排出部の開閉弁の開閉動作時に装置内に生じる静圧変動を抑えることができる。この結果、本発明によれば、静圧変動に伴う処理対象施設から本装置への処理される排気ガスの流入風量の増大を防ぐことができ、さらに、排気通路から排出される排出風量の増大も防ぐことができる。
このように構成された本発明においては、供給部及び排出部の開閉弁の開閉動作時に装置内に生じる静圧変動を抑えることができる。この結果、本発明によれば、静圧変動に伴う処理対象施設から本装置への処理される排気ガスの流入風量の増大を防ぐことができ、さらに、排気通路から排出される排出風量の増大も防ぐことができる。
このように構成された本発明においては、供給部及び排出部の開閉弁の開閉動作時に装置内に生じる静圧変動を抑えることができる。この結果、本発明によれば、静圧変動に伴う処理対象施設から本装置への処理される排気ガスの流入風量の増大を防ぐことができ、さらに、排気通路から排出される排出風量の増大も防ぐことができる。
このように構成された本発明においては、供給部及び排出部の開閉弁の開閉動作時に装置内に生じる静圧変動を抑えることができる。この結果、本発明によれば、静圧変動に伴う処理対象施設から本装置への処理される排気ガスの流入風量の増大を防ぐことができ、さらに、排気通路から排出される排出風量の増大も防ぐことができる。
このように構成された本発明においては、開閉弁のエアシリンダの排気音をより高い効率で消音することができる。また、エアシリンダの消音タンクが防音デバイス内に配置されているので、エアシリンダの排気配管からの排気音を二重に消音することができる。さらに、消音タンクは全てのエアシリンダの排気配管に共通なので、開閉弁毎即ちエアシリンダ毎に消音タンクを設ける必要がないので、構造を簡素化できる。
このように構成された本発明においては、開閉弁を駆動するエアシリンダの防音デバイスとして送風機の防音デバイスを使用するので、エアシリンダ専用の防音デバイスを設ける必要がない。
