Abstract

The invention provides an exhaust gas treatment device, a control method and control device thereof, a storage medium, a treater, an exhaust gas treatment system and a mobile carrier. The treatment device comprises MFC equipment, DPF equipment and SCR equipment which are arranged on an exhaust pipe in sequence. A first reducing agent spray nozzle is arranged on the part, on the upstream of the MFCequipment, of the exhaust pipe. A second reducing agent spray nozzle is arranged on the part, between the DPF equipment and the SCR equipment, of the exhaust pipe. The MFC equipment belongs to a multifunctional catalytic device and has the DOC function and the SCR function. The exhaust pipe belongs to an exhaust line of an engine. According to the treatment device, the DOC and SCR dual functionsare integrated in the MFC equipment, the structure of the exhaust gas after-treatment device is simplified, and the SCR conversion efficiency is improved; the exhaust gas treatment device achieves theDOC ignition function and can also reduce emissions of NOx by replacing DOC with MFC; and accordingly, the whole after-treatment device is simplified in arrangement and saves space.

Description

technical field [0001] The present application relates to the technical field of automobiles, in particular, to an exhaust gas treatment device and its control method, a control device, a storage medium, a processor, an exhaust gas treatment system and a mobile carrier. Background technique [0002] As the country has stricter requirements on the emission standards of diesel vehicle exhaust pollutants, and in order to meet the Euro VI and National VI emission standards, it is necessary to control the particulate matter, NO X (nitrogen oxides), HC (hydrocarbons) and CO (carbon monoxide) and other concentrations are controlled, therefore, it is necessary to control DOC (Diesel Oxidation Catalyst, diesel oxidation catalyst), DPF (Diesel Particulate Filter, particulate filter) and SCR (Selective Catalytic Reduction, Selective Catalytic Reduction) is integrated in the box-type after-treatment device. [0003] The traditional DOC-DPF-SCR post-processing device is difficult to con...
