The electric heating high-temperature maintenance device comprises an air supply device, an air flow meter, an electric heating device, a first particulate filter connecting section, a second particulate filter connecting section and a control cabinet, the air supply device communicates with the air inlet end of the electric heating device through an air delivery pipeline, the air flow meter is arranged on the air delivery pipeline, the electric heating device comprises a shell body and anelectric heating pipeline, the first particulate filter connecting section communicates with the air discharging end of the electric heating device through an air discharging pipeline, the particulate filter can be assembled between the first particulate filter connecting section and the second particulate filter connecting section in disassembled and assembled modes, and the second particulate filter connecting section is connected with an exhaust pipe. According to the electric heating high-temperature maintenance device of the particulate filler, the maintenance temperature is controlled accurately, and falling-off of a catalyst coating and high-temperature damage to a carrier are avoided; and the maintenance time is short, the equipment cost is low, the product application range is wide, and the maintenance cost of the particulate filler is reduced.
Description
technical field [0001] The invention belongs to the use and maintenance technology of diesel engine particulate traps, in particular to a high-temperature maintenance device for electrically heated particulate traps. Background technique [0002] With the gradual increase in the number of cars, the exhaust pollution caused by motor vehicles has become increasingly apparent. According to statistics, the emission of particulate matter from motor vehicles has accounted for about 30% of the total emissions. Diesel engine particulate matter emissions are 30 to 80 times that of gasoline engines. Reducing diesel engine particulate matter emissions is of great significance to reducing particulate matter pollution and improving residents' health. [0003] Diesel particulate filter (DPF) can effectively reduce the emission of particulate matter from diesel engines, and its filtration efficiency for particulate matter is as high as 95%. It has been applied in large quantities in China ...
