1. A section of a solid particle bed, comprising a sea zone and one or more island zones distributed in the sea zone and having an upper surface, a lower surface, an axial direction that is a length direction or a direction of a material flow in the solid particle bed from the upper surface to the lower surface, and a radial direction which is a cross-sectional direction or a direction perpendicular to the axial direction, wherein the island zone extends along the axial direction of the solid particle bed without reaching the lower surface, and a voidage of the island zone is 110-300% of a voidage of the sea zone.
