Product Description

Catalytic Converter Of cordierite Honeycomb ceramic Particulate Filter

Description :
 DPF is a special honeycomb ceramic filter which has wall-flow structure.
It  uses the micro-pores on its inner walls to remove the particulate matter from the exhaust gas of diesel engine.
It has many micro pores on its inner walls. These micro pores allow the gas going through the wall, but reject most of the particulate matter in the exhaust gas. When the exhaust gas from diesel engine enters into one DPF channel from the open end, due to the closed other end, the exhaust gas is forced to go through from the micro pores of the inner wall, and exhaust out from the neighbor open channel. In this process, those particulate matters which have bigger size than these micro pores are captured on the inner wall, and hence achieve the filtering effect.

 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 of exhaust gas and 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 zero
2. The filter element used in the system has a long service life
3. The purification system is automatically started, controlled and easy to operate
4. Intelligent regeneration control system to reduce energy consumption
5. The structure is sturdy, and the shell package is not modified
6. Assembled structure, easy to install .
