SIC Diesel Particulate Filter For Diesel Engine Exhaust System
Product Description
- The exhaust flow resistance of honeycomb ceramic particle trap
filter element is mainly proportional to the thickness of particle
layer deposited on the filter element surface. The larger the
filtration area per unit volume, the slower the growth of particle
layer thickness and flow resistance. From this point of view, the
greater the honeycomb density of the filter element, the better,
and the thinner the channel wall thickness, the better. However,
the honeycomb density is too high and the channel is too small, so
the accumulated particles will increase the exhaust flow resistance
and even block the channel. Therefore, the passage of the filter
element cannot be made too small.
- The micropores of particle traps are usually micron-sized, which is
much larger than that of soot particles. Therefore, micropores can
not directly purify, but through other mechanisms, including
diffusion mechanism, interception mechanism, inertial collision
mechanism and gravity deposition mechanism.
- Diffusion mechanism means that after the trapped particles appear
in the flow field, the trapped particles converge on the rest
particles, resulting in the concentration gradient of particle
distribution, which leads to the diffusion and transportation of
particles, and finally leads to the diffusion and capture of
particles.
- Interception mechanism means that particles with a diameter greater
than or equal to the diameter of the micropore of the filter
element are captured when approaching the filtering surface.
- Inertial collision mechanism means that when the exhaust gas flows
through micropores, the streamline bends, but because the mass of
particulate matter is much larger than that of gas micelles, it
hits the filter surface of the filter element and is trapped.
- Gravity deposition mechanism refers to the phenomenon that
particles are trapped near the filter surface under the action of
gravity, but because of the small mass of particles and the fast
exhaust velocity, the influence of gravity deposition is often
ignored.
- In the working process of DPF, the properties of particulate
matter, exhaust flow rate, temperature, DPF specifications and
material characteristics have important influence on the collection
efficiency of DPF.
