Abstract
The utility model belongs to the field of honeycomb ceramic catalytic agent carriers and discloses a spliced type honeycomb ceramic catalytic agent carrier. The spliced type honeycomb ceramic catalytic agent carrier comprises a cylindrical honeycomb ceramic body and an outer skin coated on the outer wall of the cylindrical honeycomb ceramic body. The spliced type honeycomb ceramic catalytic agent carrier is characterized in that the cylindrical honeycomb ceramic body is formed by splicing of nine honeycomb ceramic blocks, and adjacent honeycomb ceramic blocks are bonded through a bonding layer. The honeycomb ceramic with the structure meets the using requirements, the survival rate of products is greatly improved, and production cost is reduced.
Description
Technical field
The utility model belongs to the carrier for ceramic honeycomb catalyst field, relates in particular to a kind of spliced carrier for ceramic honeycomb catalyst.
Background technology
The cry that reduces motor vehicle exhaust emission is day by day strong, China has formulated the corresponding mandatory rules of law simultaneously, the emission limit of automobile progressively adds sternly, gasoline engine is administered progressively to walk to get on the right track, the improvement of diesel engine also progressively launches, some engineering machinery, large ship, bus, truck, sending out is the emission problem that also needs to be resolved hurrily such as unit, these diesel exhaust gas pipe volume are large, major diameter, the carrier for ceramic honeycomb catalyst of large volume specification could satisfy instructions for use, but the ceramic honey comb of diameter 〉=330 ㎜ can't obtain high survival rate owing to making difficulty, has greatly increased production cost.Therefore need a kind of novel structure to satisfy instructions for use, and can obtain higher survival rate.
Summary of the invention
The purpose of this utility model is the above-mentioned deficiency for prior art, and a kind of spliced carrier for ceramic honeycomb catalyst is provided.
The purpose of this utility model is achieved through the following technical solutions:
A kind of spliced carrier for ceramic honeycomb catalyst, comprise cylindrical ceramic honey comb body, and the crust of cylindrical ceramic honey comb body outer wall coating, it is characterized in that described cylindrical ceramic honey comb body is spliced by 9 ceramic honey comb pieces, bonds by tack coat between the adjacent cell ceramic body.
Wherein, described cylindrical ceramic honey comb body diameter of section size preferred 〉=330 ㎜.
The preferred 1-10 ㎜ of described adhesive layer thickness.
Described skin thickness has preferred 1-5 ㎜.
Preferred 50 ~ 400 hole/square inches of the quantity of described cylindrical ceramic honey comb body mesopore.
Concrete manufacturing process is: make first nine square ceramic honey combs, be spliced into a large square with bonding pug, cut as required the cylindrical ceramic honey comb of rear diameter 〉=330 ㎜ of composition take the center as point, plant the crust of last layer 1-5 ㎜ all around.
Beneficial effect: the ceramic honey comb of this structure had both satisfied instructions for use, had greatly improved again the survival rate of product, had reduced production cost.
Description of drawings
The spliced carrier for ceramic honeycomb catalyst structural representation of Fig. 1,
1 is cylindrical ceramic honey comb body, and 2 is crust, and 3 ~ 11 are respectively the ceramic honey comb piece, and 12 ~ 15 are respectively tack coat.
The spliced carrier for ceramic honeycomb catalyst manufacturing process of Fig. 2 schematic diagram.
The specific embodiment
A kind of spliced carrier for ceramic honeycomb catalyst as shown in Figure 1, comprise that diameter of section is of a size of the cylindrical ceramic honey comb body 1 of 330 ㎜, and the thickness that cylindrical ceramic honey comb body 1 outer wall coats is the crust 2 of 3mm, described cylindrical ceramic honey comb body 1 is spliced by 9 ceramic honey comb pieces 3 ~ 11, and the tack coat 12 ~ 15 by 2mm between the adjacent cell ceramic body bonds.
Described adhesive layer thickness is 2 ㎜.
Described skin thickness is 3 ㎜.
Concrete manufacturing process is (Fig. 2): make first nine square ceramic honey comb pieces 3 ~ 11, be spliced into a large square with bonding pug, after point cuts as required, form the cylindrical ceramic honey comb that diameter is 330 ㎜ take the center, plant the crust of last layer 3 ㎜ all around.
This joining method not only is applicable to through type heavy in section ceramic honey comb but also can be used for heavy in section intersection plug-hole formula diesel engine carbon black filter.
