Abstract
A triangle opening honeycomb ceramic support is implemented by combining the triangle openings in different combination to form novel triangle opening ceramic support structure. The pressent invention can increase the opening density and effective catalytic area, lower the processing diffculty, raise the structure strength, and increase the service life.
Description
The design and the manufacturing that the present invention relates to cellular structure ceramic carrier comprise mold machining technology." cellular structure ceramic carrier " that prior art manufactures and designs in fact all adopts square hole, do not possess the feature of polynuclear plane.There are three obvious defects in this sharp square hole ceramic monolith: one, and hole density is not high enough, and high density holes only is every flat inch 400 orders; Its two, difficulty of processing is big, yield rate only is 70%; Its three, structural strength is poor, work-ing life is uneven.
The present invention is intended to design a kind of ideal ceramic-like carrier hole structure, imitates the purpose that addresses the above problem thereby reach row.Embodiment of the present invention are: adopt Stability Analysis of Structures, tri-angle-holed structure that supporting capacity is strong to substitute original square hole structure, carry out the various novel tri-angle-holed cellular structure ceramic carrier structures that are combined to form with tri-angle-holed.Implementing the present invention can increase hole density and effective catalysis area of ceramic monolith, reduces difficulty of processing, improves structural strength, increases the service life.
Further describe each embodiment below in conjunction with accompanying drawing.
Fig. 1 is by six tri-angle-holed hexagon cellular structure ceramic carrier structure iron that combine.
Fig. 2 is by 12 tri-angle-holed hexagon cellular structure ceramic carrier structure iron that combine.
Fig. 3 is by two tri-angle-holed tetragon cellular structure ceramic carrier structure iron that combine.
Fig. 4 is by four tri-angle-holed tetragon cellular structure ceramic carrier structure iron that combine.
Fig. 5 is by eight tri-angle-holed tetragon cellular structure ceramic carrier structure iron that combine.
Fig. 1 is six tri-angle-holed hexagon cellular structure ceramic carrier structures that combine that the hole wall 2 by vestibule 1 and stupalith manufacturing constitutes, and is 400 orders per square inch with hole density, and external diameter is that the cellular structure ceramic carrier of 130mm is an example:
Single hole area S=25.4
2/ 400=1.61mm
2/ order
The square hole length of side
The tri-angle-holed length of side
The square hole perimeter L
1=1.27 * 4=5.08mm
Tri-angle-holed perimeter L
2=1.93 * 3=5.75mm
Tri-angle-holed ratio K=5.79/5.08=1.14 square hole ceramic monolith mould material hole with the square hole girth amounts to:
V
1=π (130/2)
2/ 1.27
2=8229 tri-angle-holed cellular structure ceramic carrier mould material holes amount to
V
2=π (130/2)
2/ (1.93
2.sin60 °/2)=4115 square hole ceramic monolith mould material hole diameter D
1=1mm tri-angle-holed cellular structure ceramic carrier mould material hole diameter D
2=1.7mm
Above-mentioned data show that the effective catalysis area of tri-angle-holed cellular structure ceramic carrier has increased 14% than level square hole ceramic monolith; Manufacturing square hole ceramic monolith needs to bore the miniature material hole of 8229 Φ 1mm on mould, only need the small-sized material hole of 4115 Φ 1.7mm of brill on mould to get final product if use tri-angle-holed cellular structure ceramic carrier instead, and this obviously can reduce the Mould Machining difficulty greatly.
Now pre-gaging hole density is the data of 1000 purpose tri-angle-holed cellular structure ceramic carriers per square inch:
Single hole area S '=25.4
2/ 1000=0.65mm
2/ order
The tri-angle-holed length of side
Tri-angle-holed perimeter L
3=1.22 * 3=3.66mm
The tri-angle-holed overall circumference of 1000 order tri-angle-holed cellular structure ceramic carriers and the ratio of the square hole overall circumference of 400 order square hole ceramic monoliths per square inch per square inch
K′＝(3.66×1000)/(5.08×400)＝1.80
This shows, 1000 order tri-angle-holed cellular structure ceramic carriers are compared with 400 order square hole ceramic monoliths per square inch per square inch, both are very approaching aspect the Mould Machining difficulty, and the former effective catalysis area has increased by 80% than the latter, so we are not difficult to be drawn a conclusion:, might make the density of portalling fully and be 1000 order tri-angle-holed cellular structure ceramic carriers per square inch according to existing processing conditions.For this reason, we can select the tri-angle-holed structure of various combination according to different needs.Can adopt shown in Figure 2 as making 1000 even 2000 order tri-angle-holed cellular structure ceramic carriers per square inch by 12 tri-angle-holed hexagon cellular structure ceramic carrier structures that combine, as catalysis less demanding adopt shown in Figure 3 by two tri-angle-holed tetragon cellular structure ceramic carrier structures that combine, or adopt shown in Figure 4 by four tri-angle-holed tetragon cellular structure ceramic carrier structures that combine, also available shown in Figure 5 by eight tri-angle-holed tetragon cellular structure ceramic carrier structures that combine.In a word, both saving the carrier materials, guaranteeing again to reach under the prerequisite of catalytic effect, preferred plan is to select for use per square inch 600 orders by six tri-angle-holed hexagon cellular structure ceramic carrier structures that combine.In a word, both saving the carrier materials, guaranteeing again to reach under the prerequisite of catalytic effect, preferred plan is to select for use per square inch 600 orders by six tri-angle-holed hexagon cellular structure ceramic carrier structures that combine; Less demanding as catalysis, can select for use per square inch between 400 to 600 orders by six tri-angle-holed hexagon cellular structure ceramic carrier structures that combine; Have relatively high expectations as catalysis, can select for use per square inch between 600 to 1000 orders by six tri-angle-holed hexagon cellular structure ceramic carrier structures that combine; Require as catalysis high, can select for use per square inch between 1000 to 2000 orders by 12 tri-angle-holed hexagon cellular structure ceramic carrier structures that combine.The ceramic monolith of above-mentioned various structures all is made of vestibule 1 and hole wall 2.The thickness of hole wall can be identical with conventional ceramic monolith wall thickness.
