A pyrolysis apparatus for solid hydrocarbon feedstock and a process method thereof are related to a pyrolysis apparatus and a process method thereof. A multi-tubular pyrolysis reactor of the apparatus is composed of one or more tubular pyrolysis reactors that are arranged in a tube-by-tube manner, its heating section being arranged in a heating chamber. A pyrolysis gas obtained from feedstock pyrolysis or an externally supplied fuel gas is combusted in the heating chamber through a regenerative combustion, so as to provide heat for the pyrolytic reaction. A gas collecting internal component is arranged at a center of each tubular pyrolysis reactor, and a pyrolysis gas product is regulated to radially flow across a moving particle bed so as to achieve in-situ filtering dust removal and selective cracking upgrading.
