Description
Technical field
The present invention relates to a kind of ceramic honeycomb carrier with how lateral opening shape, for purifying vehicle exhaust.Belong to ceramics to add
Construction equipment technical field.
Background technology
At present, the automobile exhaust purifier of unobstructed application both at home and abroad, its catalyst carrier are typically all carried using ceramic honeycomb
Body, this carrier are 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, it is 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 globality poor of the ceramic honeycomb carrier in metal-back, increase the resistance during vent gas treatment,
Tail gas clean-up effect is reduced, and honeycomb substrate is when mounted, complex operation, and efficiency is low；The gas of such a honeycomb substrate simultaneously
Hole is clear opening, poor to the waste gas purification effect containing black smoke particle；The pass of existing honeycomb substrate is 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 ceramic honeycomb carrier with how lateral opening shape, this
Ceramic honeycomb carrier good integrity, filter area are big, good purification and easy for installation.
The object of the present invention is achieved like this：
A kind of ceramic honeycomb carrier with how lateral opening shape, including cylindrical body, feature be：The cylindrical body is in cylindroid
Shape, the cylindrical body are densely covered with stomata in the axial direction, and one end of the stomata is opening, and the other end is provided with closure face,
The closure face and open space arrangement, the two neighboring stomata are provided with next door, are provided with next door in cellular micropore,
Catalyst coat is coated with next door, the stomata is polygonal hole, and the inwall of stomata is corrugated.
A kind of ceramic honeycomb carrier with how lateral opening shape of the present invention, the hole count of its stomata is 600 holes/square inch.
A kind of ceramic honeycomb carrier with how lateral opening shape 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 ceramic honeycomb carrier with how lateral opening shape of the present invention, good integrity, increases to greatest extent in the confined space
Filter area, and easy for installation, good purification；Micropore on next door can effectively filter the black smoke particle in waste gas, 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 ceramic honeycomb carrier with how lateral opening shape, and it is included in elliptical cylinder-shape
Cylindrical body, the cylindrical body are densely covered with stomata 1 in the axial direction, and one end of the stomata 1 is opening 6, and the other end is set
Have closure face 2, the closure face 2 and an arranged for interval of opening 6, the stomata 1 is polygonal hole, the inwall of stomata 1 be it is corrugated,
The two neighboring stomata 1 is provided with next door 3, is provided with next door 3 in cellular micropore 4, is applied on next door 3 coated with catalyst
Layer 7.
Wherein, the hole count of stomata 1 is 600 holes/square inch, and the thickness in next door 3 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 6 of stomata 1, because stomata 1 is opened at one end
Mouthfuls 6, and be then closure face 2 in the other end, therefore waste gas can be by the next door 3 with micropore 4, then opening from adjacent air holes 1
Mouth 6 is discharged, and because the diameter of black smoke particle is big compared with micropore 4, therefore the black smoke particle in waste gas will catch next door 3 by filtering
On, air-flow then passes through from micropore 4.
Active rare earth of the catalyst coat 7 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 4, urging on next door 3 is coated
Agent coating 7 will strengthen CO, HC, NOxThe activity of three kinds of gas, it is promoted to carry out certain oxidationreduction chemical reaction, wherein
CO is oxidized to colourless nontoxic carbon dioxide at high temperature, and HC compounds resolve into water at high temperature（H2O）And titanium dioxide
Carbon, NOxIt is reduced into nitrogen and oxygen.
When diesel exhaust gas temperature reaches 375 degrees Celsius, in the presence of catalyst coat 7, the black smoke on next door 3
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 fall so as to completely burned（Catalysis burning）, now the purifying rate of black smoke particle up to 90% with
On.
