BEACON The DPF high temperature regeneration performance test bench
The realization of DPF's function in the whole vehicle mainly has two parts, namely the capture of carbon particles and the reaction treatment of carbon particles. DPF generally adopts a wall-flow filter, which relies on alternately blocking the inlet and outlet of the carrier holes and forcing the airflow through the porous wall to achieve particle capture. The front-stage DOC catalyst oxidizes the NO produced by the combustion in the diesel engine cylinder to produce NO2. After entering the DPF, the NO2 molecular bond can be broken at a relatively low temperature (about 250°C), and the generated oxygen will combust with the captured C particles to form CO2. Most ordinary driving conditions of diesel engine can meet the regeneration temperature (250℃~500℃) in DPF, so PM can be effectively removed. In the particle trap, electric heating is used to generate high temperature, and the trapped particles are burned into CO2 and discharged.

(1)DPF high temperature regeneration equipment has high heating efficiency, fast speed and good effect. It not only saves electricity and energy, but is also easy to maintain and low maintenance costs. Under normal circumstances, the time block from the start of heating to the regeneration temperature. High temperature control accuracy and sensitive response
|
|
(2) The use of special scientific insulation layer design and the use of special insulation materials greatly reduce the heat loss caused by heat conduction, thereby greatly reducing energy consumption; a relatively closed regeneration environment can effectively reduce thermal radiation pollution, and then Protect the ecological environment and the health of operators.
|
|
(3) The multi-stage temperature control function design of preheating section, initial regeneration section and regeneration section can effectively protect the carrier and fully regenerate. The user can set the regeneration temperature, regeneration power, temperature retention, and temperature retention time according to actual needs. You can also optimize the power consumption according to your own power supply situation.
|
|
(4) The design has a high temperature warning light flashing function, and has multiple safety protections, so that you can use it with satisfaction, rest assured, and peace of mind!
|
|
(5) Design an air supply device to supply sufficient air required for carrier regeneration. The upper part is designed with a smoke exhaust pipe, and the smoke pipe part is equipped with smoke elimination parts, which can greatly reduce the pollution to the environment.
