Abstract
The invention discloses a carrier for a vehicle exhaust catalytic cleaner. The carrier comprises a barrel (1) and a core (2) arranged in the barrel, and is characterized in that the core (2) comprises a plurality of first parallel plates (21) and a plurality of second parallel plates (22), the first plates and the second plates are crosswise arranged to form rhombic channels (3) for exhaust to flow through, and hollows (4) are arranged on the side walls of the first plates and the second plates. The rhombic channels are formed by the crossed plates, and the hollows are arranged on the side walls of the rhombic channels, so that the carrier for the vehicle exhaust catalytic cleaner is simple to process, contact time and contact areas of catalytic coatings with the exhaust can be effectively increased, and working efficiency of the catalytic cleaner is remarkably improved.
Description
Technical field
The present invention relates to catalytic purifier for motor vehicle exhaust carrier.
Background technique
Motor-vehicle tail-gas is huge to the mankind and environmental hazard, has become one of main source of pollution of atmosphere.Catalytic conversion technique is the most effectively mode of current motor-vehicle tail-gas control, and the core of this technology is catalytic cleaner.The chief component of catalytic cleaner is carrier and catalyst coatings, realizes the catalytic purification of motor-vehicle tail-gas by apply active material on carrier.
As one of key components of catalytic cleaner, the material of carrier mainly contains two kinds, pottery and metal.Metallic carrier, because its wall is thin, percent opening is high, thermal conductivity is high, can effectively reduce exhaust resistance, improves the purification efficiency of catalyst coatings and extends working life of catalytic cleaner.In recent years, metallic carrier has obtained application more widely gradually.Metallic carrier is made up of shell and core body, and the flat board that its core body is made of metal conventionally and corrugated sheet are reeled and made.Wherein, the corrugated sheet in metallic carrier mostly is single linear ripple, and in use catalyst coatings and air-flow are short time of contact, and area of contact is little, is difficult to realize the efficient catalytic conversion of catalyst coatings.
Summary of the invention
Problem to be solved by this invention is to provide catalytic purifier for motor vehicle exhaust carrier, can effectively increase time of contact and the area of contact of catalyst coatings and tail gas, significantly improves the working efficiency of catalytic cleaner.
In order to solve the problems of the technologies described above, the present invention adopts following technological scheme: catalytic purifier for motor vehicle exhaust carrier, comprise cylindrical shell and be located at the core body in cylindrical shell, described core body comprises some the first parallel plate bodys and some the second parallel plate bodys, described the first plate body and described the second plate body are arranged in a crossed manner and form the diamond passages flowing through for air-flow, on the sidewall of described the first plate body and described the second plate body, are equipped with depression.
Improved, described depression is located at the first plate body and the second plate body intersects on the diamond passages sidewall being divided into.
Improved, described depression is evenly distributed on the sidewall of diamond passages.
Improved, described depression is circular or square or long hole shape or waveform or taper.
Improved, the acute angle of the cross section of described diamond passages is made as 60 °.
Improved, some the first parallel plate body spaced sets, some the second parallel plate body spaced sets.Diamond passages is evenly distributed in cylindrical shell, and each channel sized shape is consistent, thereby the tail gas flowing through from each diamond passages can purify totally, to purify clean level even.
Improved, described the first plate body and described the second plate body infall pass through brazing.Ensure that core body internal structure can deformation effect catalyticing purifying effect.
Improved, brazing is passed through in described core body and described cylindrical shell jointing place.Make core body can be in cylindrical shell play.
Beneficial effect:
Adopt after technique scheme, this invention catalytic purifier for motor vehicle exhaust is formed diamond passages and on diamond passages sidewall, depression is set by the plate body intersecting with carrier, processing is simple, can effectively increase time of contact and the area of contact of catalyst coatings and tail gas, significantly improve the working efficiency of catalytic cleaner.
Brief description of the drawings
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further:
