Provided are an exhaust pipe having turbulence wings, and an exhaust system. The exhaust pipe includes an outer pipe and an inner pipe. The exhaust pipe is connected to a scrubber of the exhaust system. The outer pipe has a gas inlet port. The inner pipe is installed in the outer pipe. A gap exists between the outer pipe and the inner pipe. The inner pipe includes a plurality of turbulence wings and gas discharge ports. The gas discharge ports are in communication with the gas inlet port via the gap. The turbulence wings project inward from the inner pipe and are disposed adjacent to the gas discharge ports. The inner pipe has an exhaust gas passage formed therein. When a gas is flowed through the gas discharge ports and over the turbulence wings, a jet layer is formed adjacent to an interior sidewall of the inner pipe. The jet layer forms a buffer between the exhaust gas passage and the inner pipe sidewalls. In this way, exhaust gases passing through the exhaust gas passage are prevented from contacting the inner pipe surface. Absorption of exhaust gas byproducts at the surface of the exhaust pipe is therefore reduced.
