Diesel engine aftertreatment device with combustor and DDPF

The invention discloses a diesel engine post-treatment device with a combustor and a DDPF. The diesel engine post-treatment device is used for increasing the temperature of exhaust gas entering post-treatment, increasing the temperature of the exhaust gas in the DDPF and SCR, increasing the conversion efficiency of HC, CO and NOx and improving the emission quality of tail gas emission. The device comprises a barrel type combustor, a diesel oxidation catalytic particle trap (DDPF) and a selective catalytic reduction (SCR). The barrel type combustor comprises a combustor body, an air inlet and an air outlet; the combustor body is connected with the DDPF, and the DDPF has a DOC function and a DPF function; and the DDPF is connected with the SCR, so that after exhaust gas enters the combustor body from the gas inlet and is heated, the heated exhaust gas sequentially enters the DDPF and the SCR from the gas outlet. 本申请公开了一种带有燃烧器和DDPF的柴油机后处理装置，用于提升进入后处理的排气温度，提高排气在DDPF和SCR中的温度，提升HC，CO，NOx的转化效率，提高尾气排放的排放质量。本申请装置包括：桶式
