Description

High-temperature regeneration furnace for regeneration of vehicle aftertreatment device

Technical Field

The utility model relates to a regenerator especially relates to a high temperature regenerator for regeneration of automobile-used aftertreatment device.

Background

The main functions of the vehicle aftertreatment devices (including DOC, CDPF and SCR of diesel engines, GPF and TWC of gasoline engines) are to purify PM (particulate matter), CO carbon monoxide, HC hydrocarbons, NOx nitrogen oxides in exhaust gas. The harmful substances in the exhaust gas are mainly soot PM particulate matters generated by fuel combustion, NOx nitrogen oxide, CO, carbon monoxide and HC hydrocarbon. Since it is an after-treatment device for purifying exhaust gas, clogging, crystallization, poisoning, aging and failure are inevitable as the use time increases. In order to achieve the treatment purification effect, the carriers in the post-treatment device are coated with the noble metal Pt, Pd, Rh and rhodium, and the post-treatment device can be maintained instead of directly replaced as the noble metal with extremely high cost. As the service life increases, the carrier is subjected to harmful gas catalysis and particulate matter collection to form blockage, toxic aging and failure, so that the exhaust back pressure is increased, the purification capacity is reduced, and the power performance and the environment are influenced. There are two ways to restore vehicle performance, namely, vehicle aftertreatment regeneration and replacement of aftertreatment systems (extremely high cost). When the particulate matters are accumulated to a certain degree and the post-treatment purification capacity is reduced, the plug can be burnt out through regeneration, the purification capacity is recovered through the reverse reaction of the noble metal, the effect of treating pollution for no secondary pollution is achieved, and the resource waste is reduced.
