【発明の属する技術分野】
本発明は、蓄熱燃焼式排ガス浄化装置に対する排ガス給排方法およびその装置に係り、より詳しくは揮発性有機化合物などの可燃性有害成分を含有する排ガスを燃焼処理する蓄熱燃焼式排ガス浄化装置に対して複数のポペット式ダンパを連動させて開閉することにより前記排ガスの給排を行うようにした蓄熱燃焼式排ガス浄化装置に対する排ガス給排方法およびその装置に関する。
【０００２】
【従来の技術】
従来、 揮発性有機化合物などの可燃性有害成分を含有する排ガスを燃焼処理する蓄熱燃焼式排ガス浄化装置に対して複数のポペット式ダンパを連動させて開閉することにより前記排ガスの給排を行うようにした設備がある（例えば、特許文献１参照）。

【０００４】
しかし、このように構成された従来の蓄熱燃焼式排ガス浄化装置に対する排ガス給排装置においては、供給側のポペット式ダンパと、排出側のポペット式ダンパとが一瞬ではあるが同時に２個以上「開」の状態になり、これに伴って蓄熱燃焼式排ガス浄化装置による圧力損失が低下して蓄熱燃焼式排ガス浄化装置に供給される排ガスの量が増大し、蓄熱燃焼式排ガス浄化装置の静圧変動などの問題があった。
【０００５】
本発明は、上記の問題を解消するために成されたもので、その目的は、供給側のポペット式ダンパと排出側のポペット式ダンパとが同時に２個以上「開」の状態になった時にも蓄熱燃焼式排ガス浄化装置の静圧変動を防止する方法およびその装置を提供することにある。
【０００６】
【課題を解決するための手段】
上記の目的を達成するために本発明における蓄熱燃焼式排ガス浄化装置に対する排ガス給排方法は、揮発性有機化合物などの可燃性有害成分を含有する排ガスを燃焼処理する蓄熱燃焼式排ガス浄化装置に対して複数のポペット式ダンパを連動させて開閉することにより前記排ガスの給排を行うようにした蓄熱燃焼式排ガス浄化装置に対する排ガス給排方法において、前記蓄熱燃焼式排ガス浄化装置の排ガス供給側および排出側にそれぞれ設けた複数のポペット式ダンパのうち少なくとも２個以上のポペット式ダンパがほぼ同時に開くことにより、前記蓄熱燃焼式排ガス浄化装置による圧力損失が低下した時に、前記排出側ポペット式ダンパから排出された処理済排ガスの一部を前記蓄熱燃焼式排ガス浄化装置の排ガス供給側に配設した送風機の吸引側に送り込むようにすることを特徴とする。
【０００７】
【発明の実施の形態】
以下、本発明を適用した排ガス処理設備の一実施例について図１に基づき詳細に説明する。本排ガス処理設備は、揮発性有機化合物などの可燃性有害成分を含有する排ガスを燃焼処理する蓄熱燃焼式排ガス浄化装置１と、蓄熱燃焼式排ガス浄化装置１の排ガス供給側および排出側にそれぞれ設けた複数のポペット式ダンパを連動させて開閉することにより蓄熱燃焼式排ガス浄化装置１に対して前記排ガスの給排を行うようにした排ガスの給排手段２と、複数のポペット式ダンパのうち少なくとも２個以上のポペット式ダンパがほぼ同時に開くことにより前記蓄熱燃焼式排ガス浄化装置１による圧力損失が低下した時に前記排出側ポペット式ダンパから排出された処理済排ガスの一部を前記蓄熱燃焼式排ガス浄化装置１の排ガス供給側に配設した送風機の吸引側に送り込む排ガス回帰手段３とで構成してある。
【０００８】
そして、前記排ガスの給排手段２においては、排ガスが発生する排ガス発生装置（図示せず）と連通するダクト４の先端に送風機５の吸引口が接続してあり、送風機５の放出口にはダクト６の一端が接続してある。ダクト６の他端は２個のポペット式ダンパ７・８をそれぞれ介して前記蓄熱燃焼式排ガス浄化装置１の排ガス供給口にそれぞれ接続してあり、蓄熱燃焼式排ガス浄化装置１の排ガス排出口には２個のポペット式ダンパ９・１０およびダクト１１を介して排気ダクト１２が接続してある。そして、前記ダクト４には圧力伝送器１３が、また前記ダクト６には差圧伝送器１４を備えたオリフィス流量計２１がそれぞれ装着してあり、前記送風機５の電動機１５に装着したインバータ１６、前記圧力伝送器１３および差圧伝送器１４はコントローラ１７を介して相互に電気的に接続してある。
【０００９】
また、前記排ガス回帰手段３においては流量調整ダンパ１８を付設したダクト１９が前記ダクト４・１１間に連通接続してあり、流量調整ダンパ１８のポジショナ２０は前記コントローラ１７に電気的に接続してある。
【００１０】
このように構成されたものは、未処理の排ガスをダクト４に誘導するとともに送風機５によって加圧してダクト６に送り込み、複数のポペット式ダンパ７〜１０を連動させて開閉することにより、蓄熱燃焼式排ガス浄化装置１に対して排ガスの給排を行い所定の処理する。そして、圧力伝送器１３によって測定したダクト４内の圧力および差圧伝送器１４によって測定したオリフィス流量計２１の差圧に基づき、コントローラ１７を介して流量調整ダンパ１８の開度を調整する。
【００１１】
このようにして排ガスを処理している途中で、ポペット式ダンパ７〜１０のうち少なくとも２個以上のポペット式ダンパが同時に「開」の状態になり、これに伴って蓄熱燃焼式排ガス浄化装置１による圧力損失が低下して蓄熱燃焼式排ガス浄化装置１に供給される排ガス量が増大しようとした時、圧力伝送器１３および差圧伝送器１４による測定結果に基づき、流量調整ダンパ１８がコントローラ１７によって制御されて、ポペット式ダンパ９・１０から排出された処理済の排ガスがダクト１９および流量調整ダンパ１８を介してダクト４に戻される。これにより、ポペット式ダンパの同時「開」による蓄熱燃焼式排ガス浄化装置１への排ガスの供給量の増大を防止することができる。
【００１２】
【発明の効果】
以上の説明から明らかなように本発明は、揮発性有機化合物などの可燃性有害成分を含有する排ガスを燃焼処理する蓄熱燃焼式排ガス浄化装置に対して複数のポペット式ダンパを連動させて開閉することにより前記排ガスの給排を行うようにした蓄熱燃焼式排ガス浄化装置に対する排ガス給排方法において、前記蓄熱燃焼式排ガス浄化装置の排ガス供給側および排出側にそれぞれ設けた複数のポペット式ダンパのうち少なくとも２個以上のポペット式ダンパがほぼ同時に開くことにより、前記蓄熱燃焼式排ガス浄化装置による圧力損失が低下した時に、前記排出側ポペット式ダンパから排出された処理済排ガスの一部を前記蓄熱燃焼式排ガス浄化装置の排ガス供給側に配設した送風機の吸引側に送り込むようにするから、供給側ポペット式ダンパと排出側ポペット式ダンパとが同時に「開」の状態になった時にも蓄熱燃焼式排ガス浄化装置への排ガスの供給量が増大しないため、蓄熱燃焼式排ガス浄化装置の静圧変動を低減することができるなどの優れた実用的効果を奏する。
