DescriptionHoneycomb ceramic silicon carbide DPF diesel
particulate filter for engines
exhaustDPF is a special honeycomb ceramic filter that has wall-flow structure.
It
uses the micro-pores on its inner walls to remove the particulate matter from the exhaust gas of diesel engines.With
the increasing appearance of diesel engine automobiles, the
particulate from emissions, mainly carbon, enhances the pollution
of the environment. Regulation for diesel engines, stipulates the
particulate in diesel passenger cars emissions should meet the
criterion: below 2.0g/mile. The diesel particulate filter is able
to filter above 80% carbon smoke particulate. For practical
application, it would be a great help to solve the problem of air
pollution.As one of the leading technologies to meet current PM
emission standards, a diesel particulate filter (DPF)has been
developed for the exhaust after-treatment. Most of the commercially
available DPFS are ceramic honeycomb filters. However, due to the
limitation of the DPF volume, whose porosity is about 0.4, the
filter would be plugged with particles, which causes an increase in
the filter backpressure [6,8,9]. If the backpressure is too high,
the engine may stall or the fuel consumption rate may increase. An
establishment of a new PM treatment technology without recourse to
the catalyst is urgently required. Thus, it is important to develop
a non-catalytic exhaust after treatment. There is an alternative,
the silicon carbide (SiC) ceramic foam filter.Installation Method:
The product is installed in the exhaust system of a diesel engine
and uses a wall-flow method to filter particulate five (PM) with a
removal efficiency of up to 98%. It is an effective means to
control the black smoke phenomenon of exhaust gas, and it can also
greatly reduce noise pollution. We can produce various types of
traps with a hole density of 100 mesh and 200 mesh. The product can
meet the emission standards of EURO v, EURO vi, EPA, etc., and can
be widely used in diesel vehicles and general machinery.Features
:1. The black smoke treatment and deodorization effect is obvious,
and the opacity is close to zero2. The filter element used in the
system has a long service life3. The purification system is
automatically started, controlled, and easy to operate4.
Intelligent regeneration control system to reduce energy
consumption5. The structure is sturdy, and the shell package is not
modified6. Assembled structure, easy to
installStructure and working principle: The DPF
substrate has a special structure with one end open and the other
closed. There are many micropores on its inner wall. These
micropores allow gases to pass through the walls but reject most of
the particulate matter in the exhaust. When diesel engine exhaust
gas enters one DPF channel from the open end, since the other end
is closed, the exhaust gas is forced to pass through the micropores
in the inner wall and be discharged from the adjacent open channel.
During this process, those particles larger than these pore sizes
are trapped on the inner wall, thus achieving the filtering
effect.1. The DPF can capture more than 95% particulate matter.2. The porosity of DPF is more than 50%.
