Triangular ceramic honeycomb carrier of corrugated hole form

Abstract

The invention relates to a triangular ceramic honeycomb carrier of a corrugated hole form. The triangular ceramic honeycomb carrier of the corrugated hole form comprises a columnar body, and the section of the columnar body is triangular. The columnar body comprises a first edge (1), a second edge (2) and a third edge (3). Air holes (4) are densely distributed in the columnar body in the axis direction. An opening (9) is formed in one end of each air hole (4), and a blocking surface (5) is arranged at the other end of each air hole (4). The air holes (4) are square, and the inner wall of each air hole (4) is corrugated. A partition wall (6) is arranged between every two adjacent air holes (4). Micropores (7) which are distributed in a honeycomb shape are formed in the partition walls (6). The partition walls (6) are coated with catalyzer coatings (10). According to the triangular ceramic honeycomb carrier of the corrugated hole form, the filter area is enlarged to the maximum extent in a limited space, and the purification effect is good; and black smoke particles in waste gas can be effectively filtered out through the micropores in the partition walls and can be burned under the effect of the catalyzer coatings, and the tail gas purification effect is further improved.

Description

technical field [0001] The invention relates to a triangular ceramic honeycomb carrier with corrugated holes, 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 honey...

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 of the exhaust gas containing black smoke particles is poor; the cell type of the existing honeycomb carrier is Round hole, the inner wall of the round hole is straight, so the filter area is small
