DPF carrier regeneration workbench

Abstract

The invention discloses a DPF carrier regeneration workbench. The workbench comprises a combustor, an air blower, an air inlet pipe, a transition pipe and an exhaust tail pipe, the air blower is connected with the combustor through the air inlet pipe so as to blow air into the combustor, the combustor is connected with the inlet end of a DPF carrier through the transition pipe, and the exhaust tail pipe is connected with the outlet end of the DPF carrier. A nozzle and an ignition electrode are arranged on the combustor, the nozzle is externally connected with an oil spraying pipe to input fueloil into the combustor, the fuel oil is ignited by the ignition electrode and then is combusted in the combustor, the combusted fuel gas and heated air form mixed gas, then particles filtered and captured on the DPF carrier are ignited, and high-temperature regeneration of the DPF carrier is achieved. The regenerated mixed gas is discharged from the exhaust tail pipe. According to the DPF carrierregeneration workbench, the combustor is used for combusting the fuel oil for heating, the fuel oil utilization rate is high, the total regeneration time is shorter, the comprehensive cost is lower,in addition, an electronic controller is used for automatically controlling the whole regeneration process, the control precision is high, and operation is easy.

Description

technical field [0001] The invention relates to the technical field of diesel engine particulate trapping system regeneration, in particular to a DPF carrier regeneration workbench. Background technique [0002] With the country's emphasis on environmental protection, vehicles powered by internal combustion engines and non-road mobile machinery need to install exhaust treatment equipment to purify the pollutants in the exhaust. For diesel engines, one of the main exhaust pollutants is exhaust particulate matter with soot as the main component. Therefore, it has become common to install a diesel particulate filter (DPF) system on a diesel engine to remove exhaust particulate matter. For a diesel engine installed with a DPF system, after the DPF system filters and captures a certain amount of particulate matter, the pressure difference between the front and rear ends of the DPF carrier increases, which will lead to an increase in the exhaust back pressure of the diesel engine...

AI Technical Summary

Problems solved by technology

Due to the use of an electric furnace to raise the temperature, the temperature control is simple and the temperature control accuracy is high, but the energy consumption is also relatively high, and the cost required to complete the regeneration is correspondingly high

Moreover, the power load is very high, and the power supply of ordinary small maintenance stations cannot bear it. Therefore, its practical application is greatly restricted.
