Title:
EXHAUST EMISSION CONTROL SYSTEM
Document Type and Number:
Japanese Patent JP2012251512
Kind Code:
A
Abstract:
To provide an exhaust emission control system that prevents high-temperature emission gas from flowing into a selective reduction catalyst (SCR) to remove NOx in order to prevent damage to the SCR.
The exhaust emission control system 1 is configured to allow exhaust gas being a purification target to flow thereinto in order to purify the exhaust gas. The system includes a reducing-agent supply part 5 in which an oxidization catalyst part 2, a selective reduction catalyst part 3, and a particulate-matter combustion catalyst part 4 are sequentially arranged from the upstream side of the flowed-in exhaust gas and which supplies a reducing agent to the selective reduction catalyst part 3.
