The annular negative pressure cylinder comprises an outer cylinder wall, a cylinder top plate, an inner cylinder wall and a curved subdivision plate assembly, the outer cylinder wall is welded to the lower portion of the cylinder top plate, radiation reinforcing toggle plates are welded to the upper portion of the cylinder top plate, transverse reinforcing toggle plates are arranged along the circumferential radius of the cylinder top plate in a multi-circle mode, and the inner cylinder wall is welded to the lower portion of the cylinder top plate. An upper lip plate is coaxially welded to the upper portion of the inner cylinder wall, the inner cylinder wall and the outer cylinder wall form an annular structure, and a curved subdivision plate assembly is welded between the outer side of the inner cylinder wall and the inner side of the outer cylinder wall. The inner cylinder wall and the outer cylinder wall are divided by adopting the curved subdivision plates, so that the buckling strength of the subdivision
