Noise reduction type three-way catalyst structure

The utility model relates to the technical field of three-way catalytic converters, in particular to a noise reduction type three-way catalytic converter structure which comprises a three-way catalytic converter shell and a baffle, the right end of the three-way catalytic converter shell is fixedly connected with an exhaust part, and noise reduction devices are installed at the two ends of the interior of the three-way catalytic converter shell. A connecting device is installed in the middle of the interior of the three-way catalyst shell. According to the three-way catalytic converter, automobile exhaust can enter the three-way catalytic converter shell through the air inlet part, at the moment, the automobile exhaust can be preliminarily dispersed through the screen plate on the connecting plate and floats to the fan blades, so that the fan blades can be driven to rotate automatically, and the automobile exhaust can be further dispersed through the fan blades; according to the three-way catalytic converter
