Description
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.

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 ******0
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.
