Specific embodiment
Referring to Fig. 1-8, the present invention relates to a kind of exhaust gas filter of black smoke good filtration effect, it includes Rose Box 1, the first drainage screen 2, the first ceramic honeycomb carrier 3, the second ceramic honeycomb carrier 7 and the second drainage screen 8, the left end of Rose Box 1 is inlet exhaust gas 4, right-hand member is offgas outlet 5, described first drainage screen 2, the first ceramic honeycomb carrier 3, the second ceramic honeycomb carrier 7 and the second drainage screen 8 are arranged in Rose Box 1,, at inlet exhaust gas 4, the second drainage screen 8 is at offgas outlet 5 for first drainage screen 2.
Described Rose Box 1 is in cylinder, described first ceramic honeycomb carrier 3 is identical with the structure of the second honeycomb substrate 7, and shape is corresponding with crossing filtering case 1, first ceramic honeycomb carrier 3 is densely covered with pore 3.1 in the axial direction, one end of described pore 3.1 is opening 3.6, the other end is provided with closure face 3.2, described closure face 3.2 and opening 3.6 arranged for interval, described two neighboring pore 3.1 is provided with next door 3.3, have on next door 3.3 in cellular micropore 3.4, next door 3.3 is coated with catalyst coat 3.5.
The front end of Rose Box 1 is additionally provided with water inlet pipe 10 and fog-spray nozzle 11, and water inlet pipe 10 is connected with fog-spray nozzle 11, and fog-spray nozzle 11 stretches in filter, and spraying liquid adopts the aqueous sodium carbonate of pH10.
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.
Described first drainage screen 2 is made using stainless steel material，Oblique backfin 2.1 and longitudinal belling 2.2 are provided with the first drainage screen 2，Fig. 7 is the expanded view of the first drainage screen 2，Axial direction when laterally rolling for the first drainage screen 2 in way，Radial direction when longitudinally rolling for the first drainage screen 2，During use，It is arranged in Rose Box 1 after first drainage screen 2 is wound，Backfin 2.1 and the first drainage screen 2 body form gas channel 9，Gas channel 9 intersection forms multiple rhombus expansion slots，And every a segment distance, one cut-off is formed by belling 2.2，When motor exhaust blows to gas channel 9，A part shunts along gas channel 9，A part passes through the first drainage screen 2 bulk filter，Partial tail gas along gas channel 9 shunting can produce different degrees of turbulent flow when through expansion slot and cut-off，Form the shunting of multiple directions，The black smoke granule in tail gas is enable fully to be captured on the first drainage screen 2 body，When black smoke granule capturing to a certain amount of when，Can be burnt under the high temperature of engine exhaust formation CO2, thus realizing the function of filter regeneration
Described second drainage screen 8 is made using absorbent charcoal material.Second drainage screen 8 is that drainage screen with activated carbon can adsorb to the first drainage screen 2 and the untreated CO (carbon monoxide converter) gas of the second ceramic honeycomb carrier 7.
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 granule that Diesel engine is discharged enter，The aqueous sodium carbonate first passing around fog-spray nozzle ejection is processed，Eliminate the acid ingredient in tail gas，It is then passed through the single filter of the first drainage screen 2，Carry out cascade filtration subsequently into the first ceramic honeycomb carrier 3，Enter from the opening 3.6 of pore 3.1，Because 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，Because the diameter of black smoke granule is big compared with micropore 3.4，Black smoke granule therefore in waste gas will be caught on next door 3.3 by filtering，Air-flow then passes through from micropore 3.4，The waste gas discharged from the first ceramic honeycomb carrier 3 enters the second ceramic honeycomb carrier 7，Carry out three-stage filtration，The same cascade filtration of work principle of filter，The waste gas discharged from the second ceramic honeycomb carrier 7 enters the second drainage screen 8 and carries out level Four filtration，The carbon monoxide of residual is adsorbed.
The active rare earth containing noble metal for the described catalyst coat 3.5, Main Ingredients and Appearance has Pt, Pd, Rh, Al2O3, Ce, La, Zr, Cu, Mn, the waste gas of diesel combustion（The predominantly harmful gass such as CO, HC, NOx）During through micropore 3.4, the catalyst coat 3.5 on coating next door 3.3 will strengthen CO, HC, NOxThe activity of three kinds of gases, promotes it to carry out certain oxidation-reduction chemical reaction, wherein CO is oxidized to colourless nontoxic carbon dioxide at high temperature, 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; black smoke granule on next door 3.3 can progressively burn and aoxidize; the purifying rate of black smoke granule about reaches more than 85%, and when reaction temperature reaches 500 degrees Celsius, catalyst and black smoke particle reaction are thus burn completely（Catalysis burning）, now the purifying rate of black smoke granule is up to more than 90%.
