Embodiment
Referring to Fig. 1-9, the present invention relates to a kind of exhaust gas filter for the black smoke good filtration effect for adjusting tail gas resistance, it is wrapped Include Rose Box 1, the first screen pack 2, the first ceramic honeycomb carrier 3, the second ceramic honeycomb carrier 7 and the second screen pack 8, Rose Box 1 left end is inlet exhaust gas 4, and right-hand member is offgas outlet 5, first screen pack 2, first the 3, second ceramics of ceramic honeycomb carrier The screen pack 8 of honeycomb substrate 7 and second is arranged in Rose Box 1, and the first screen pack 2 is at inlet exhaust gas 4, the second screen pack 8 At offgas outlet 5.
The Rose Box 1 is in cylinder, and 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, and the first ceramic honeycomb carrier 3 is densely covered with stomata 3.1, the one of the stomata 3.1 in the axial direction Hold as opening 3.6, the other end is provided with closure face 3.2, the closure face 3.2 and the arranged for interval of opening 3.6, described two neighboring Stomata 3.1, which is provided with next door 3.3, next door 3.3, to be provided with cellular micropore 3.4, and catalyst coat is coated with next door 3.3 3.5。
Wherein, the hole count of stomata 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 of stainless steel material, and the oblique He of backfin 2.1 is provided with the first screen pack 2 The belling 2.2 of longitudinal direction, Fig. 7 is the expanded view of the first screen pack 2, axial direction when laterally being rolled for the first screen pack 2 in way, is indulged To radial direction when being rolled for the first screen pack 2, in use, being arranged on after the first screen pack 2 is wound in Rose Box 1, backfin 2.1 and the body of the first screen pack 2 formation gas channel 9, the intersection of gas channel 9 forms multiple rhombus expansion slots, and every One segment distance forms a cut-off by belling 2.2, when motor exhaust blows to gas channel 9, and a part is along 9 points of gas channel Stream a, part passes through the bulk filter of the first screen pack 2, and the partial tail gas shunted along gas channel 9 is passing through expansion slot and cut-off When can produce different degrees of turbulent flow, form the shunting of multiple directions, the black smoke particle in tail gas is fully captured in the On the body of one screen pack 2, when black smoke granule capturing to it is a certain amount of when, can burn to form CO at a high temperature of engine exhaust2, from And realize the function of filter regeneration
Second screen pack 8 is made of absorbent charcoal material.Second screen pack 8 can be with for the screen pack with activated carbon First screen pack 2 and the untreated CO gas of the second ceramic honeycomb carrier 7 are adsorbed.
The filter also include standby carrier 14, cover plate 10, supporting plate 11, stage clip 12 and axle 13, standby carrier 14 with Ceramic honeycomb carrier 3 is arranged side by side, and one end of axle 13 is offseted by supporting plate 11 with Rose Box 1, the other end and cover plate of axle 13 10 connections, the offgas outlet of cover plate 10 and standby carrier 14 coordinates, and stage clip 12 is set on axle 13, its one end and the phase of cover plate 10 Support, the inwall of the other end and Rose Box 1 offsets.
Under normal circumstances, cover plate 10 seals the offgas outlet of standby carrier 14, when the pressure in Rose Box 1 exceedes permissible value When, this pressure can push up plate 10 of uncapping, and tail gas is discharged from standby carrier 14, so as to solve the problem of exhaust emissions resistance is big, made Obtain engine stabilizer operation.
Operation principle：The present invention is fabricated to honeycomb ceramic carrier using cordierite, and is built in diesel engine vent gas purification In device, the waste gas inlet exhaust gas 4 with black smoke particle of Diesel engine discharge enters, by the one-level mistake of the first screen pack 2 Filter, carries out secondary filtration subsequently into the first ceramic honeycomb carrier 3, enters from the opening 3.6 of stomata 3.1, because stomata 3.1 exists One end is opening 3.6, and is 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 Discharged from the opening 3.6 of adjacent air holes 3.1, because the diameter of black smoke particle is big compared with micropore 3.4, therefore the black smoke particle in waste gas It will be caught by filtering on next door 3.3, air-flow is then passed through from micropore 3.4, the waste gas discharged from the first ceramic honeycomb carrier 3 enters Second ceramic honeycomb carrier 7, carries out three-stage filtration, the same secondary filtration of work principle of filter, from giving up that the second ceramic honeycomb carrier 7 is discharged Gas enters the second screen pack 8 and carries out level Four filtering, and the carbon monoxide of residual is adsorbed.
Active rare earth of the catalyst coat 3.5 containing noble metal, Main Ingredients and Appearance has 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, next door is coated Catalyst coat 3.5 on 3.3 will strengthen CO, HC, NOxThe activity of three kinds of gas, promotes it to carry out certain oxidationreduction Reaction is learned, wherein CO is oxidized to colourless nontoxic carbon dioxide at high temperature, and HC compounds resolve 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, on next door 3.3 Black smoke particle can progressively burn and aoxidize, and the purifying rate of black smoke particle about reaches more than 85%, when reaction temperature reaches that 500 take the photograph Catalyst and black smoke particle reaction so as to burn completely when family name spends（Catalysis burning）, now the purifying rate of black smoke particle is reachable More than 90%.
