Abstract
【解決手段】断熱配管1は、内部を流体が流通可能な配管2と、配管2を覆うように配置された断熱部材3とを備え、配管2がSCR触媒を用いる排気ガス浄化装置に用いられ、断熱部材3が、独立気泡構造をしており、雰囲気との熱の交換による流体の温度上昇を抑制できるので、SCR触媒を用いる排気ガス浄化装置において、配管2の内部が断熱部材3によって外部と断熱されて、雰囲気との熱の交換による配管2の内部を流通する流体の温度上昇を抑制できる。
【選択図】図1
Description
図1に示す断熱配管1は、内部を流体が流通可能な配管2と、配管2を覆うように配置された断熱部材3とを備える。断熱配管1は、配管2に沿うように配置され、内部を加熱された流体が流通可能な温水配管4をさらに備えている。配管2と温水配管4とは、柔軟性を有し、円筒形状をしている。配管2と温水配管4とを形成する素材は、内部を流通する液体に応じて選択される。配管2は流体としての尿素水が内部を流通でき、温水配管4は加熱された流体としての不凍液が流通できるように素材が選択されている。本実施形態の場合、配管2と温水配管4とは樹脂で形成されている。
図3に示すように、断熱配管1は例えば建設機械11のSCRシステム12に用いられる。建設機械11は、例えばショベルカー等の建設作業に用いられる機械である。建設機械11は、エンジン13、エンジン13から排出された排気ガスが流れる排気管14、熱を外部へ放出させるラジエーター15、及びラジエーター15を冷却する冷却ファン16が格納されたエンジンルーム17と、建設機械11を操縦する操縦者が乗り込むキャビン18とを備えている。SCRシステム12は、機体前方に設けられたキャビン18と機体後方に設けられたエンジンルーム17の間の空間に配置されている。
本発明は上記実施形態に限定されるものではなく、本発明の趣旨の範囲内で適宜変更することが可能である。例えば、配管2、断熱部材3、温水配管4、結束部材5、固定部材10、継手6a、6b、保護部材8、9については、材質や形状を適宜変更することが可能である。
