Irregular-shaped ceramic honeycomb carrier with protective sleeve

Abstract

The invention relates to an irregular ceramic honeycomb carrier with a protective sleeve. It includes an irregular columnar body, the columnar body is densely covered with air holes (4) along the axial direction, one end of the air holes (4) is an opening (9), and the other end is provided with a sealing surface (5), the sealing surface ( 5) and the opening (9) are arranged at intervals, and a partition (6) is provided between two adjacent air holes (4), and there are micropores (7) arranged in a honeycomb shape on the partition (6), and the partition (6) coated with a catalyst coating (10), and a sleeve (12) is arranged outside the columnar body, and the sleeve (12) includes an outer plate (12.1) and an inner plate (12.2), and the outer plate (12.1) and Corrugated plates (12.3) are arranged between the inner plates (12.2). The invention provides an irregular ceramic honeycomb carrier with a protective sleeve, which has good integrity, good purification effect, effective shock resistance, and protects the honeycomb carrier.

Description

technical field [0001] The invention relates to an irregular ceramic honeycomb carrier with a protective sleeve, 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 ho...

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 vibration brought by the engine will affect the honeycomb carrier. , causing damage to the honeycomb carrier and affecting the filtering effect
