Secondary combustion chamber of vehicle-mounted incinerator

The secondary combustion chamber of the vehicle-mounted incinerator comprises a supporting assembly component, a waste gas containing component, a combustion-supporting air supply component and a heat exchange containing component, the secondary combustion chamber of the vehicle-mounted incinerator is formed by connecting sectional materials to form a supporting frame, and an outer end shell plate and an inner end shell plate are installed on the supporting frame to form a waste gas containing space. A heat exchange housing is installed on the supporting frame to form a heat exchange space, and a waste gas through opening is formed in an inner end shell plate inclining towards the inclined upper portion, so that waste gas exhausted by a fire grate combustion chamber smoothly enters a waste gas containing space in the rising process, the waste gas combustion process is smoothly carried out, a secondary combustion chamber and the fire grate combustion chamber are transversely arranged, and the heat exchange eff
