Abstract

The invention discloses a catalyzing device for purifying motor vehicle exhaust. The catalyzing device comprises a shell, a catalyst carrier, a liner and an outer layer. The shell comprises a body part, an air inlet part and an air outlet part, wherein the air inlet part and the air outlet part are located on the two sides. The catalyst carrier is located in the body part. The liner is arranged between the catalyst carrier and the body part. The catalyst carrier sequentially comprises a first carrier and a second carrier in the air inlet direction, wherein the first carrier comprises a pair of upper carrier body and lower carrier body, and the opposite faces of the upper carrier body and the lower carrier body are protruding arc faces; and the second carrier and the first carrier are arranged side by side and are in close contact, and the second carrier comprises an inner core. The outer layer comprises an outer shell located on the outermost layer and multiple layers of first partition plates sequentially arranged around the inner core, wherein a triangular unit space is formed between every two adjacent first partition plates, and the end face of the inner core and the end faces of the first partition plates in the shell are in a protruding shape. By means of the catalyzing device for purifying the motor vehicle exhaust, due to the arrangement that the second-stage catalyst carrier is combined with the partition plates, the time for airflow flowing through the catalyst carrier is prolonged, the catalyzing reaction is more sufficient, and the utilization rate of the catalyzing device is effectively increased.

Description

technical field [0001] The invention relates to the technical field of motor vehicle exhaust emission. More specifically, the present invention relates to a catalytic device for purifying motor vehicle exhaust. Background technique [0002] With the rapid development of the economy, people's demand for motor vehicles is increasing day by day, the production and ownership of domestic motor vehicles have increased sharply, and the problem of motor vehicle exhaust pollution has become more and more serious. Motor vehicle pollution control measures are divided into two types: internal purification and external control. Among them, the catalytic converter is an important part to improve vehicle emissions and reduce vehicle exhaust pollution. Its exterior is made of double-layer stainless steel sheets. The heat insulating material - asbestos fiber felt is installed in the double-layer thin board interlayer, and the cleaning agent is installed in the middle of the mesh partition i...
