Specific embodiment
Referring to Fig. 1-5，The present invention relates to a kind of environment-friendly type exhaust gas filter，It includes Rose Box 1、First screen pack 2、Ceramic honeycomb carrier 3 and the second screen pack 7，The left end of Rose Box 1 is inlet exhaust gas 4，Right-hand member is offgas outlet 5，First screen pack 2、Ceramic honeycomb carrier 3 and the second screen pack 7 are arranged in Rose Box 1，First screen pack 2 is at inlet exhaust gas 4，Second screen pack 7 is at offgas outlet，The Rose Box 1 includes the first arc-shaped edges 1.1、Second arc-shaped edges 1.2、First hypotenuse 1.3 and the second hypotenuse 1.4，First arc-shaped edges 1.1、Second hypotenuse 1.4、Second arc-shaped edges 1.2 and the first hypotenuse 1.3 are joined end to end successively，Connecting place adopts round-corner transition，The shape of the ceramic honeycomb carrier 3 is corresponding with Rose Box 1，And ceramic honeycomb carrier 3 is densely covered with pore 3.1 in the axial direction，One end of the pore 3.1 is opening 3.6，The other end is provided with closure face 3.2，The closure face 3.2 and 3.6 arranged for interval of opening，The two neighboring pore 3.1 is provided with next door 3.3，Have on next door 3.3 in cellular micropore 3.4，Catalyst coat 3.5 is coated with next door 3.3.
Hush pipe 8 is provided between the import of the front end of the Rose Box 1 and ceramic honeycomb carrier 3, the outlet of hush pipe 8 is connected with the import of ceramic honeycomb carrier 3, the entrance of hush pipe 8 is provided with arm 9 with holes on two walls.
Wherein, the hole count of pore 3.1 is 600 holes/square inch, and the thickness in next door 3.3 is 0.13 ~ 0.14mm.
First screen pack 2 is made using copper monoxide material, and the second screen pack 7 is made using absorbent charcoal material.As copper monoxide has very strong oxidisability, so the oxidation of moment will be carried out when the carbon monoxide with reproducibility is run into which, produce the carbon dioxide of not atmosphere pollution, whole process is exactly a redox process, and the second screen pack 7 is that screen pack with activated carbon can adsorb to the first screen pack 2 and the untreated CO gas of ceramic honeycomb carrier 3.
Operation principle：The present invention is fabricated to honeycomb ceramic carrier using cordierite，And be built in exhaust purifier of diesel engine，The waste gas inlet exhaust gas 4 with black smoke particle that Diesel engine is discharged are entered，Single filter through the first screen pack 2，Cascade filtration is carried out subsequently into ceramic honeycomb carrier 3，Tail gas is entered from the opening 3.6 of pore 3.1，As pore 3.1 is opening 3.6 at one end，And be then closure face 3.2 in the other end，Therefore waste gas can be by the next door 3.3 with micropore 3.4，Then discharge from the opening 3.6 of adjacent air holes 3.1，As the diameter of black smoke particle is big compared with micropore 3.4，Therefore the black smoke particle in waste gas will be caught on next door 3.3 by filtering，Air-flow is then passed through from micropore 3.4，The waste gas that discharges from ceramic honeycomb carrier 3 enters the second screen pack 7 and carries out three-stage filtration，Carbon monoxide to remaining adsorbs.
Active rare earth of the catalyst coat 3.5 containing noble metal, Main Ingredients and Appearance have Pt, Pd, Rh, Al2O3, Ce, La, Zr, Cu, Mn, the waste gas of diesel combustion（The predominantly pernicious gas such as CO, HC, NOx）During through micropore 3.4, coat the catalyst coat 3.5 on next door 3.3 and will strengthen CO, HC, NOxThe activity of three kinds of gases, promotes which to carry out certain oxidationreduction chemical reaction, and wherein CO is oxidized to colourless nontoxic carbon dioxide at high temperature, and HC compound resolves into water at high temperature（H2O）And carbon dioxide, NOxIt is reduced into nitrogen and oxygen.
When diesel exhaust gas temperature reaches 375 degrees Celsius, in the presence of catalyst coat 3.5, the black smoke particle on next door 3.3 can progressively burn and aoxidize, and the purifying rate of black smoke particle about reaches more than 85%, when reaction temperature reaches 500
Degree Celsius when catalyst and black smoke particle reaction so as to burn completely（Catalysis burning）, now the purifying rate of black smoke particle is up to more than 90%.
