產品描述

Diesel Particulate Filter is one kind of wall flowed honeycomb ceramic filter with special structure and material. It is applied in the tail gas clean-up plant of diesel. It utilizes the pore of wall flowed filter to cut-off and catch the soot particulate in the tail gas of diesel and then purifies the tail gas. It is made by two materials: Cordierite and carborundum.

Dimension:
Channel density-100/200channels/ square inch
Specification(mm):
Dia144*150
Dia150*150
Dia286*355...

Characteristic:
1, Large and compact area per unit volume
2, Small pressure loss and excellent capturing performance
3, Excellent heat resistance and heat BHLJock resistance.

If the DPF is coated with noble metal (such as PT, Pd and Rh), the particulate of emission is captured inside thin gas hole or entrance. As it lasts, the cumulated layer become thick, and pressure loss increase. To ensure the performance of engine, when pressure loss reaches some value, it is a must to recycle the filter. The recycle is making the particulate burning, by raising the gas temperature of filter. The particulate condition is related to the oxygen concentration. Normally, it is burning at 550-650 celsius degree Usually we raise emission temperature by adjusting throttle, and increase gas temperature with burner. The particulate burning temperature can be decreased by catelyzer, making cumulative particulate burning as soon as possible, thus recover the pressure loss and fitters performance, then the filter is recycled.
