Description
Technical field
The present invention relates to a kind of triangle ceramic honeycomb carrier with ripple pass, for purifying vehicle exhaust.Belong to
Ceramic manufacturing equipment technical field.
Background technology
At present, the automobile exhaust purifier of unobstructed application both at home and abroad, its catalyst carrier is typically all carried using ceramic honeycomb
Body, this carrier is to add adhesive with synthesis of dichroite raw material, burn and lose agent, blended spice, pugging, extrusion, drying, sintering,
Then impregnated catalyst re-dry is made.In use, being put into exhaust purifier metal shell stage casing.
Conventional ceramic honeycomb carrier is generally square cylinder, and it is net that the ceramic honeycomb carrier of such a shape is loaded into tail gas
When changing in the metal shell of device, often cause the space between ceramic honeycomb carrier and metal shell big so that tail gas clean-up
Device can not effectively utilize the space of automobile chassis, and some producers can add the pottery of small dimension to plug the gap in gap
Porcelain honeycomb substrate, this can cause the resistance during the globality poor of the ceramic honeycomb carrier in metal-back, increase vent gas treatment,
Tail gas clean-up effect is reduced, and honeycomb substrate is when mounted, and complex operation, efficiency is low；While the gas of such a honeycomb substrate
Hole is clear opening, poor to the waste gas purification effect containing black smoke particle；The pass of existing honeycomb substrate be circular hole, circular hole it is interior
Wall is straight, therefore filter area is small.
The content of the invention
It is an object of the invention to overcome above-mentioned deficiency, there is provided a kind of triangle ceramic honeycomb load with ripple pass
Body, this ceramic honeycomb carrier good integrity, filter area are big, good purification, easy for installation.
The object of the present invention is achieved like this：
A kind of triangle ceramic honeycomb carrier with ripple pass, including cylindrical body, are characterized in：The cylindrical body
Section is triangle, including first while, second while and the 3rd side, described first while, second while and the connecting place on the 3rd side use
Round-corner transition, the cylindrical body is densely covered with stomata in the axial direction, and one end of the stomata is opening, and the other end is provided with envelope
It is provided with next door, next door and is provided with honeycomb between stifled face, the closure face and open space arrangement, the two neighboring stomata
Catalyst coat is coated with the micropore of shape arrangement, next door, the stomata is square hole, and the inwall of stomata is corrugated.
A kind of triangle ceramic honeycomb carrier with ripple pass of the present invention, the hole count of its stomata is 600 holes/square English
It is very little.
A kind of triangle ceramic honeycomb carrier with ripple pass of the present invention, the thickness in its next door is 0.13 ~ 0.14mm.
Compared with prior art, the beneficial effects of the invention are as follows：
A kind of triangle ceramic honeycomb carrier with ripple pass of the present invention, good integrity, in the confined space to greatest extent
Increase filter area, and easy for installation, good purification；Micropore on next door can effectively filter the black smoke in waste gas
Grain, and black smoke particle can be burned off in the presence of catalyst coat, further increase tail gas clean-up effect.

Embodiment
Referring to Fig. 1-4, the present invention relates to a kind of triangle ceramic honeycomb carrier with ripple pass, it includes column sheet
Body, the section of the cylindrical body is triangle, including first at 1, second 2 and the 3rd side 3, and described first at 1, second
2 and the 3rd the connecting place on side 3 use round-corner transition, the cylindrical body is densely covered with stomata 4 in the axial direction, the stomata 4
One end is opening 9, and the other end is provided with closure face 5, the closure face 5 and the arranged for interval of opening 9, and the stomata 4 is square hole, gas
The inwall in hole 4 is corrugated, is provided with next door 6, next door 6 and is provided with cellular arrangement between the two neighboring stomata 4
Catalyst coat 10 is coated with micropore 7, next door 6.
Wherein, the hole count of stomata 4 is 600 holes/square inch, and the thickness in next door 6 is 0.13 ~ 0.14mm.
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 with black smoke particle of Diesel engine discharge enters from the opening 9 of stomata 4, because stomata 4 is opened at one end
Mouthfuls 9, and be then closure face 5 in the other end, therefore waste gas can be by the next door 6 with micropore 7, then opening from adjacent air holes 4
Mouth 9 is discharged, because the diameter of black smoke particle is big compared with micropore 7, therefore the black smoke particle in waste gas will catch next door 6 by filtering
On, air-flow is then passed through from micropore 7.
Active rare earth of the catalyst coat 10 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 7, on coating next door 6
Catalyst coat 10 will strengthen CO, HC, NOxThe activity of three kinds of gas, promotes it to carry out certain oxidationreduction chemistry anti-
Should, wherein CO is oxidized to colourless nontoxic carbon dioxide at high temperature, and HC compounds resolve into water at high temperature（H2O）With
Carbon dioxide, NOxIt is reduced into nitrogen and oxygen.
When diesel exhaust gas temperature reaches 375 degrees Celsius, in the presence of catalyst coat 10, the black smoke on next door 6
Particle can progressively burn and aoxidize, and the purifying rate of black smoke particle about reaches more than 85%, when reaction temperature reaches 500 degrees Celsius
When catalyst and black smoke particle reaction so as to burning completely（Catalysis burning）, now the purifying rate of black smoke particle up to 90% with
On.
