Integrated container, post-treatment exhaust system and vehicle

The invention relates to an integrated container, an after-treatment exhaust system and a vehicle. The integrated container comprises a container bottom plate, a liquid pipeline is installed on the container bottom plate, the liquid pipeline is arranged in a bent mode and flatly laid in the container bottom plate, and a communicating pipe communicates between the two ends of the liquid pipeline; the tail gas pipeline is arranged in the liquid pipeline, the bent path of the tail gas pipeline is consistent with that of the liquid pipeline, a tail gas inlet of the tail gas pipeline penetrates out of the liquid pipeline, and a tail gas outlet of the tail gas pipeline also penetrates out of the liquid pipeline. Tail gas exhausted by the engine is used for heating the container, secondary utilization of energy is achieved, the problems that the container of the dumper freezes and adheres to goods in winter and unloading is difficult are effectively solved, meanwhile, the problem that the arrangement space of a wate
