Kidney-shaped ceramic honeycomb carrier

Abstract

The invention relates to a kidney-shaped ceramic honeycomb carrier which comprises a column body with the kidney-shaped section. Air pores (1) are densely distributed in the column body in the axis direction, an opening (6) is formed in one end of each air pore (1), and a blocking face (2) is arranged at the other end of each air pore (1). The blocking faces (2) and the openings (6) are arranged alternately. A partition wall (3) is arranged between every two adjacent air pores (1), and each partition wall (3) is provided with micro-pores (4) distributed in a honeycomb shape and coated with a catalyst coating (7). The column body is mounted in an outer sleeve which comprises an outer plate (8.1), an inner plate (8.2) and a corrugated plate (8.3). The kidney-shaped ceramic honeycomb carrier is good in integrity, and the filtering area is enlarged in a limited space to the maximum extent; the micro-pores in the partition walls can effectively filter black smoke particles in waste gas, and the black smoke particles are burned up under the action of the catalyst coatings; and meanwhile, the kidney-shaped ceramic honeycomb carrier is high in strength and long in service life.

Description

technical field [0001] The invention relates to a waist-shaped 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
