A self-cleaning special-shaped corrugated structure wall pipe, comprising a smooth wall inner pipe (1). A corrugated outer pipe (2) is wound outside of the smooth wall inner pipe (1). The section outline of the smooth wall inner pipe (1) is shaped like a sunflower seed. The large end of the section outline is an arc-shaped top (3), and the small end of the section outline is an arc-shaped bottom (4). The side face is a side arc part (5) tangentially connected to the arc-shaped top (3) and the arc-shaped bottom (4), and the side arc part (5) is tangent to the lower half part of the circle where the arc-shaped top (3) and the arc-shaped bottom (4) are located. A blow-off pipe has the advantages of having a high pollution discharge capacity, a low blockage probability and being capable of self-cleaning. In addition, the pipe is characterized by being lightweight, using few materials, having a high structural strength and being easy to mount.
