This utility model one high porosity particulate filter, the thickness in its next door is 0.13 ~ 0.14mm, and the porosity in next door is 50%, and the aperture of micropore is 6-10 μm。
Compared with prior art, the beneficial effects of the utility model are:
1. this utility model one high porosity particulate filter, is provided with hush pipe in Rose Box, hush pipe arranges arm, increases the contact area of tail gas and hush pipe, contributes to guiding air-flow, plays sound deadening。
2. this utility model one high porosity particulate filter, the next door porosity is relatively big, and therefore tail gas is in filter process, and the resistance being subject to is little, good filtration effect；Simultaneously because the aperture of the micropore in next door is less, the little granule in tail gas does not pass through the micropore in next door, further increases filter effect。
3. this utility model one high porosity particulate filter; ceramic honeycomb carrier is outside equipped with sleeve; sleeve includes outside plate and inner panel; it is provided with corrugated plating between described outside plate and inner panel; the vibration that electromotor brings is offset by sleeve; ceramic honeycomb carrier obtains and is effectively protected, and improves the service life of filter。

Detailed description of the invention
Referring to Fig. 1-4, this utility model relates to a kind of high porosity particulate filter, it includes Rose Box 1, drainage screen 2 and ceramic honeycomb carrier 3, the left end of Rose Box 1 is inlet exhaust gas 4, right-hand member is offgas outlet 5, described drainage screen 2 and ceramic honeycomb carrier 3 are arranged in Rose Box 1, drainage screen 2 is near inlet exhaust gas 4 place, the shape of described 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 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 interval are arranged, described adjacent two pores 3.1 are provided with next door 3.3, next door 3.3 have in cellular micropore 3.4, next door 3.3 is coated with catalyst coat 3.5。
Described ceramic honeycomb carrier 3 is outside equipped with sleeve 9, and described sleeve 9 includes outside plate 9.1 He
Inner panel 9.2, is provided with corrugated plating 9.3 between described outside plate 9.1 and inner panel 9.2, owing to electromotor is in running, inevitably shakes, ceramic honeycomb carrier 3 under the protection of sleeve 9, will not because of vibration damaged in collision。
Being provided with hush pipe 7 between front end and the import of ceramic honeycomb carrier 3 of described Rose Box 1, the outlet of hush pipe 7 is connected with the import of ceramic honeycomb carrier 3, and the import department of hush pipe 7 is provided with two arms 8, and the wall of described arm 8 has hole。
Wherein, the thickness in next door 3.3 is 0.13 ~ 0.14mm, and the porosity in next door 3.3 is 50%, and the aperture of micropore 3.4 is 6-10 μm。
Operation principle: honeycomb ceramic carrier of the present utility model, it is built in exhaust purifier of diesel engine, the waste gas inlet exhaust gas 4 with black smoke granule that Diesel engine is discharged enters, single filter through drainage screen 2, subsequently into ceramic honeycomb carrier 3, enter from the opening 3.6 of pore 3.1, owing to pore 3.1 is at one end opening 3.6, it is then closure face 3.2 at the other end, therefore waste gas can pass through the next door 3.3 with micropore 3.4, then discharge from the opening 3.6 of adjacent air holes 3.1, owing to the diameter relatively micropore 3.4 of black smoke granule is big, therefore the black smoke granule in waste gas is by filtered seizure next door 3.3, air-flow then passes from micropore 3.4。
The described catalyst coat 3.5 active rare earth containing noble metal, Main Ingredients and Appearance has Pt, Pd, Rh, Al2O3, Ce, La, Zr, Cu, Mn, when the waste gas (being mainly the harmful gass such as CO, HC, NOx) of diesel combustion is through micropore 3.4, is coated in the catalyst coat 3.5 on next door 3.3 and will strengthen CO, HC, NOxThe activity of three kinds of gases, promotes it to carry out certain oxidation-reduction chemical reaction, and wherein CO is at high temperature oxidized to colourless nontoxic carbon dioxide, and HC compound at high temperature resolves into water (H2And carbon dioxide, NO O)xIt is reduced into nitrogen and oxygen。
When diesel exhaust gas temperature reaches 375 degrees Celsius; under the effect 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%; when reaction temperature reaches 500 degrees Celsius, catalyst and black smoke particle reaction are thus burning (catalysis burning) completely, and now the purifying rate of black smoke granule is up to more than 90%。
This utility model one high porosity particulate filter, is provided with hush pipe 7 in Rose Box 1, hush pipe 7 arranges arm 8, increases the contact area of tail gas and hush pipe 7, contributes to guiding air-flow, plays sound deadening；The porosity in next door 3.3 is relatively big, and therefore tail gas is in filter process, and the resistance being subject to is little, good filtration effect；Simultaneously because the aperture of micropore 3.4 is less, the little granule in tail gas does not pass through the micropore 3.4 in next door 3.3, further increases filter effect；Ceramic honeycomb carrier 3 is outside equipped with sleeve 9; sleeve 9 includes outside plate 9.1 and inner panel 9.2, is provided with corrugated plating 9.3 between described outside plate 9.1 and inner panel 9.2, and the vibration that electromotor brings is offset by sleeve 9; ceramic honeycomb carrier 3 obtains and is effectively protected, and improves the service life of filter。
