Problems solved by technology

[0003] The patent of the present invention is to solve the single structure and defect of the gas filtration channel on the honeycomb shape of the microporous ceramic carrier in the above-mentioned exhaust gas purification device, which is a combination of a straight line and a T shape; The dust particles contained in the generated exhaust gas will block the gas filter channel, and at the same time, it will reduce and reduce the contact area and time of the three-way catalyst coating coated on the surface of the porous ceramic carrier with the exhaust gas, resulting in Due to the short service life of the exhaust gas purification device and other reasons, a method is proposed to prevent the fine dust particles contained in the exhaust gas...

Embodiment Construction

[0008] The device of the present invention will be further described below in conjunction with the embodiments and accompanying drawings.

[0009] As shown in the figure, when the exhaust gas enters the shell 1 of the exhaust gas purifier, the exhaust gas after separation and purification by the first set of exhaust gas purification device 2 will produce some turbulence, and the exhaust gas will pass through the second set of exhaust gas purification device 2 After being rectified, the exhaust gas rectification channel 3 with a distance of 500 mm to 600 mm flows into the second set of exhaust gas purification device 2 for re-separation and purification treatment. To be precise: the fine dust particles contained in the exhaust gas emission are only the objects to be collected after passing through the two sets of exhaust gas purification devices, and will not cause blockage in the gas filtration channel composed of the microporous ceramic carrier grid sheet Phenomenon. The exh...

Abstract

The invention discloses a waste gas purifier to purify particle and dust in the fuel engine, which is characterized by the following: the waste gas generates turbulent current separated by first grouped of waste gas filtering device, which flows in the second group of waste gas filtering device to dispose again through commutating channel, the waste gas is disposed repeatedly by ternary catalyst on the porous ceramic carrier grid board surface in the filtering device, which reduces carbonic oxide into carbon dioxide and water as well as oxynitrides into nitrogen with purifying rate over 90%.

Description

Technical field: [0001] The patent of the present invention relates to an exhaust gas purifier, in particular to an exhaust gas purifier in a fuel internal combustion engine exhaust emission treatment system. Background technique [0002] Due to the single structure and defects of the exhaust gas purification device in the exhaust gas emission treatment system at home and abroad, it is impossible to effectively separate and clean the fine dust particles contained in the exhaust gas emission of the internal combustion engine. The effect of the actual purification treatment. Most of its exhaust gas purification devices use a microporous ceramic carrier honeycomb shape, coated with a three-way catalyst coating to capture fine dust particles contained in the exhaust gas, and to treat hydrocarbons (HC) and carbon monoxide (CO) in the exhaust gas. ) is oxidized to carbon dioxide (CO 2 ) and moisture (H 2 O), the reduction of nitrogen oxides (NOx) to nitrogen (N 2 ) and oxygen ...
