Abstract

The invention discloses a tail gas purification device for a vehicle, and the vehicle. The tail gas purification device for the vehicle comprises a shell, a gas inlet pipe and a gas outlet pipe. The gas inlet pipe is at least partially arranged in the shell. The gas outlet pipe is connected with the shell. A gas flow channel is formed between an outlet of the gas outlet pipe and an inlet of the gas inlet pipe. A tail gas purification structure used for purifying gas flowing in from the inlet and flowing out from the outlet is arranged in the gas flow channel. The gas flow channel at least comprises a forward flow section and a reverse flow section. The gas flow direction in the forward flow section is opposite to the gas flow direction in the reverse flow section. The tail gas purificationdevice is more compact in structure, and the larger-capacity tail gas purification structure can be arranged in a small axial space so that tail gas can be fully purified in a smaller axial length range of the tail gas purification device, and thus, the tail gas purification device occupies a smaller space and can be mounted on a vehicle.
