Abstract
The utility model discloses a catalyst carrier for motorcycle tail gas purifier, comprising the carrier (3) and a dipping layer (5). The structural character of the utility model is that the carrier (3) shows column-shaped and forms a body by one time; a plurality of axial direction through holes (2) are arranged inside of the carrier (3); the section of the through holes (2) shows triangle or polygon. The inner hole walls (4) of the through holes (2) are provided with an alloy catalyst dipping layer (5). The carrier (3) has high structural strength, good heat resistance, multi-throughhole, large dipping area of the catalyst. The utility model has long service life, reasonable price, good purifying effect of tail gas discharging, and the utility model can be widely used for the motorcycle tail gas purifier.
Description
Technical field
The utility model relates to a kind of motorcycle tail gas cleaning device, especially a kind of purifier catalyst carrier.
Background technique
In the existing motorcycle tail gas cleaning device, all catalyst carrier need be installed, just can make exhaust emissions reach discharging standards.And catalyst carrier all adopts the welding of heating resisting metal thin slice to form at present, be subjected to the restriction in its carrier inside structure and welding space, formed number of openings is few in it, impregnation catalyst dosage is just few on its through-hole wall, and welding is also not too firm between the hole wall, therefore, behind the motorcycle driving certain hour, its exhaust emissions temperature raises, and sheet metal easily deforms, the welding part is easy to crack, cost price height not only, and cause the catalyst carrier cisco unity malfunction, shorten working life, the tail gas clean-up effect descends, and exhaust emissions does not reach discharging standards.
Technology contents
Short at the working life that above-mentioned purifier catalyst carrier exists, the tail gas clean-up effect does not reach the problem of discharging standards, and the utility model provides a kind of long service life, reasonable price, the exhaust purifier catalyst carrier of good tail gas purification effect.
The utility model uses the cordierite refractory material to suppress in mould, and through the once-through of high-temperature baking burning, its structural feature is: the purifier catalyst carrier is cylindrical, have the through hole that several axially are parallel to each other substantially in it, triangular in shape or the polygonal of through hole section is adsorbed with the catalyst soakage layer on the through-hole wall.
The utility model has a lot of triangle through holes in order to make in the carrier, the triangle through hole is up and down symmetrical parallel, and about staggered W shape arrange.
The utility model integral one-step molding, its structural strength height, good heat resistance, through hole is many, and the catalyst soakage area is big, thereby long service life not only, and reasonable price, and exhaust emissions good purification are widely used in the motorcycle tail gas cleaning device and use.
Description of drawings
Fig. 1 is an axial arrangement schematic representation of the present utility model,
Fig. 2 is a radial structure schematic representation of the present utility model.
Embodiment
In Fig. 1 and Fig. 2, catalyst carrier 3 is used cordierite refractory material and other auxiliary material to be blended in the mould and is suppressed, and through the once-through of high-temperature baking burning, catalyst carrier 3 is cylindrical, its external diameter is the 30-70 millimeter, length is the 40-100 millimeter, have several through holes that axially is parallel to each other substantially 2 in it, be adsorbed with catalyst soakage layer 5 on through hole 2 hole walls 4, impregnated material is a platinum, palladium, rhodium binary or ternary alloy, through hole 2 sections are triangular in shape, and triangle through hole 2 is up and down symmetrical parallel, and about staggered W shape arrange, through hole 2 numbers are every square centimeter of 6-10, the through hole hole wall is thick to be the 0.16-0.25 millimeter, can coat one deck insulator 1 on its carrier 3 external cylindrical surfaces, and through hole 2 also can be polygonal.
Claims (3)
1, a kind of motorcycle tail gas cleaning device catalyst carrier, it comprises carrier (3), impregnate layer (5), it is characterized in that: carrier (3) is cylindrical, has several through holes that axially is parallel to each other substantially (2) in it, the triangular in shape or polygonal of through hole (2) section.
2, the described a kind of motorcycle tail gas cleaning device catalyst carrier of root a tree name claim 1 is characterized in that; Triangle through hole (2) is up and down symmetrical parallel, and about staggered W shape arrange.
3, the described a kind of motorcycle tail gas cleaning device catalyst carrier of root a tree name claim 1 is characterized in that: impregnate layer (5) is platinum, palladium, rhodium binary or ternary alloy.
