Automobile tail gas purification treatment device

The invention relates to an automobile tail gas purification treatment device. The automobile tail gas purification treatment device comprises a shell, the shell is provided with an air inlet and an air outlet, a light-catalyzed reaction unit and a dust removing box containing dust removing liquid are sequentially arranged in the shell in the flowing direction of tail gas, the light-catalyzed reaction unit comprises a metal mesh loaded with a catalyst and LED lamp tubes, a tail gas inlet pipe is arranged in the dust removing box, a tail gas outlet hole is formed in the dust removing box, tailgas treated by the light-catalyzed reaction unit is introduced into the dust removing liquid in the dust removing box through the tail gas inlet pipe, and the tail gas obtained after dust removing isexhausted through the tail gas outlet hole. According to the automobile tail gas purification treatment device, the light-catalyzed reaction unit is arranged in the shell to conduct catalytic oxidation on the tail gas for the
