Problems solved by technology

At present, there are many kinds of purification devices for automobile exhaust, but the effects are not very satisfactory. Recently, someone has designed a kind of automobile exhaust purification device. Alloy grids or orifices containing platinum, rhodium, palladium and other metals, and alumina particles are arranged between the grids or orifices. The automobile exhaust purifier with the above structure, due to the c

Embodiment Construction

[0018] exist figure 1 In the schematic diagram of the cross-sectional perspective diagram of the manufacturing method of the through-flow oxidation type particle filter burner, one side of the front connection plate 1 is connected to the engine exhaust pipe, and the other side is connected to one end of the front metal shell 2; the front metal shell 2. It is a through-type hollow shell with a thick center and thin ends. The thick part in the middle is inlaid with a metal foam three-way catalyst carrier 3, and a temperature sensor 4 is inlaid in the upper middle of the end of the front metal shell 2; the front metal shell 2 The end is connected to one side of the connecting plate 5, and the other side of the connecting plate 5 is connected to one end of the rear metal shell 6; the shape of the rear metal shell 6 is basically similar to that of the front metal shell 2, and a ceramic honeycomb three-way catalyst is installed in the thick middle part Carrier 7, a carbon fiber part...

Abstract

The invention relates to a manufacture method of a through flow type oxide particle filtering combustor, which belongs to the car tail gas purification field and is mainly characterized in that: cordierite honeycomb ceramics made in China is modified by transition metal oxide of mixed rare earth tailings to be used as a first carrier, modified aluminum oxide is used as a second carrier, and noble metals of Pt, Rh and Pd are used as active components and are combined with a metal foam carrier coated with different modified formulations of the modified aluminum oxide, a temperature sensor, a carbon fiber particle combustor and a shell. The through flow type oxide particle filtering combustor can lead carbon particles which can not be completely combusted when the starting temperature is lower to be completely combusted, and the modified matter of the modified aluminum used as the catalyst is the rare earth tailing with low cost. The invention saves energy and protects environment.

Description

technical field [0001] The invention relates to the field of automobile tail gas purification of diesel and gasoline engines, and relates to a manufacturing method of a through-flow oxidation type particulate filter burner. Background technique [0002] With the rapid increase of automobile production, the exhaust gas emitted by automobiles has become a mobile source of pollution, which is very harmful to the atmosphere. The United States emits 200-213 million tons of pollutants into the atmosphere from automobiles every year. Japan also emits 6 million tons of pollutants into the atmosphere from automobiles every year. CO.HC.NO in vehicle exhaust 2 .Constituents such as lead compounds and sulfides are extremely harmful to the human body. In order to eliminate this serious social pollution, the United States, Europe, Japan and other countries and regions have successively formulated strict emission regulations. In this country, governance or control of vehicle exhaust em...
