Problems solved by technology

[0010] The new honeycomb carrier structure provided by the present invention changes the form of a single exhaust gas flow channel, and adds a reverse sinusoidal structure or a triangular structure small tooth on the basis of the original sinusoidal wave tooth, so that it changes from the original single straight-through channel structure to Multi-channel structure, so as to solve the problems of uneven gas flow distribution and insufficient catalyst utilization of traditional metal honeycomb carriers

Embodiment 1

[0060] With reference to accompanying drawing, prepare a kind of metal honeycomb carrier that changes traditional sinusoidal wave pattern and make it into multi-channel, described metal is conventional commercially available Fe-Cr-Al alloy, utilizes such as Figure 5 The rolling gear set shown in the figure rolls the metal material which is initially a thin flat plate 4 into a structured corrugated plate 12, cuts the thin flat plate and the corrugated plate to the same length according to the required carrier size, and stacks and uses at least one Layers of locally structured corrugated plates and thin flat plates are stacked and rolled in sequence to form an S-shaped structural carrier core, such as figure 1 As shown; the metal honeycomb core body is placed in the metal shell 21 and fixed; the whole is formed as a multi-channel metal honeycomb carrier by arranging solder brazing. Such as figure 1 and 3 As shown, the monolithic honeycomb carrier has three different segments ...

Abstract

The invention provides an integrated honeycomb carrier with a multi-channel structure. The integrated honeycomb carrier has an inflow side end face (1) and an outflow side end face (2) and having a plurality of channels flowing in one direction, is provides with a core body formed by at least one thin flat plate (4) arranged in a layered manner and at least one partially structured corrugated sheet (5), the structure of the corrugated sheet forms a hole wall in the flowing direction of the channel, the integral honeycomb carrier has a plurality of different sections (I, II and III) in the flowing direction, and corrugated sheets (3) with sinusoidal waveforms are arranged between the adjacent structured corrugated sheet at intervals. According to the integrated honeycomb carrier, the prepared catalyst device is more uniform in gas flow distribution in the tail gas purification process, and the utilization rate of the catalyst can be improved.

Description

technical field [0001] The invention belongs to the technical field of catalytic degradation and emission reduction of automobile exhaust pollutants, and in particular relates to an integral honeycomb carrier with a multi-channel structure, and more particularly relates to changing the traditional sinusoidal wave channel structure into a multi-channel channel and changing the single flow direction of exhaust gas High-performance metal honeycomb carrier. Background technique [0002] Automobile exhaust has become the main source of air pollution. At present, the honeycomb three-way catalyst system is mainly used at home and abroad to reduce the emission of exhaust pollutants. In the automobile exhaust system, an external purification device of catalytic reduction is installed, which can effectively remove CO, HC, and NO in the exhaust gas. x and other harmful substances are transformed into harmless CO through oxidation and reduction 2 、H 2 O and nitrogen, etc. The exter...
