Cylindrical ceramic honeycomb carrier

Abstract

The invention relates to a cylindrical ceramic honeycomb carrier. The carrier comprises a cylindrical body. Pores (1) are densely arranged along the axial direction of the cylindrical body. One end of each pore (1) is an opening (6), and the other end is provided with a plugging surface (2). The plugging surfaces (2) and the openings (6) are alternatively arranged. A partition wall (3) is arranged between two neighbored pores (1). Honeycomb liked micro holes (4) are arranged in each partition wall (3). A catalyst coating (7) is painted on each partition wall (3). The cylindrical body is arranged in an outer sleeve, which comprises an outer plate (8.1), an inner plate (8.2), and a corrugated plate (8.3). The provided cylindrical ceramic honeycomb carrier has a good integrity, the filtering area is maximally increased in a limited space; the micro holes in the partition walls can effectively filter black smoke particles in exhaust gas, the black smoke particles are burned under the effect of the catalyst coatings, and the provided cylindrical ceramic honeycomb carrier has the advantages of high strength and long service life.

Description

technical field [0001] The invention relates to a cylindrical ceramic honeycomb carrier, which is used for purifying automobile tail gas. It belongs to the technical field of ceramic processing equipment. Background technique [0002] At present, the catalyst carrier of automobile exhaust purifiers widely used at home and abroad generally adopts ceramic honeycomb carrier. Drying, sintering, and then impregnated with catalyst and then dried. When in use, put it into the middle section of the metal casing of the exhaust gas purifier. [0003] The conventional ceramic honeycomb carrier is generally a square cylinder, and when the ceramic honeycomb carrier of this shape is put into the metal shell of the exhaust gas purifier, the gap between the ceramic honeycomb carrier and the metal shell will often be large, making the exhaust gas purifier The space of the car chassis cannot be effectively used, and some manufacturers will add small-sized ceramic honeycomb carriers to the ...

Problems solved by technology

[0003] The conventional ceramic honeycomb carrier is generally a square cylinder, and when the ceramic honeycomb carrier of this shape is put into the metal shell of the exhaust gas purifier, the gap between the ceramic honeycomb carrier and the metal shell will often be large, making the exhaust gas purifier The space of the car chassis cannot be effectively used, and some manufacturers will add small-sized ceramic honeycomb carriers to the gaps in order to fill the gaps, which will result in poor integrity of the ceramic honeycomb carriers in the metal shell and increase the resistance during the exhaust gas treatment process. The exhaust gas purification effect is reduced, and when the honeycomb carrier is installed, the operation is complicated and the efficiency is low; at the same time, the air holes of this kind of honeycomb carrier are straight through holes, and the purification effect on the exhaust gas containing black smoke particles is poor; the existing honeycomb carrier has no outer sleeve , so easy to wear, poor strength, short service life
