EXHAUST EMISSION CONTROL DEVICE

To reduce effects by pulsation generated by an intermittent exhaust operation of an engine.SOLUTION: An exhaust emission control device 10 includes: an exhaust gas receiver 20 having a cylindrical body 21, inflow sections 22 provided in the body 21 and causing exhaust gas from an engine to flow into the body 21 and a discharge section 23 that is provided in the body 21 and from which the exhaust gas in the body 21 is discharged; a nozzle 31 for spraying at least one of a reducing agent and a reducing agent precursor into the exhaust gas in the body 21; and an NOx removal reactor 40 to which the exhaust gas discharged from the discharge section 23 flows in. The discharge section 23 is formed to have a cylindrical shape having an inner diameter smaller than that of the body 21, penetrates through the body 21 and has an inner end 24 protruded into the body 21.SELECTED DRAWING: Figure 2 【課題】エンジンの間欠的な排気動作によって発生する脈動による影響を低減すること。【解決手段】排ガス浄化装置１０は、円筒状の本体２１と、本体２１に設けられ、エンジンの排ガスが本体２１に流入する流入部２２と、本体２１に設けられ、本体２１内の排ガスが排出される排出部２３とを有する排ガス受け２０と、本体２１内の排ガス中に還元剤および還元剤前駆体の少なくとも一方を噴霧するノズル３１と、排出部２３から排出された排ガスが流入する脱硝反応器４０とを備える。排出部２３は、内径が本体２１の内径よりも小さい筒状に形成され、本体２１を貫通し内方端２４が本体２１内に突出している。【選択図】図２
