A large-caliber polytetrafluoroethylene ventilation compensator comprises a compensator body, scouring protection devices are arranged at the two ends of the compensator body, each scouring protection device comprises a compensator protection sleeve, the compensator protection sleeves are arranged on channel openings in the two ends of the compensator body, compensator flanges are further arranged at the two ends of the compensator body, and the compensator flanges are connected with the compensator protection sleeves. A corrugated polytetrafluoroethylene pipe is further arranged between the compensator flange and the compensator protection sleeve, the technical problem that due to the fact that some granular media are often contained in acid mist gas, the compensator body is prone to being abraded when the acid mist gas flows through the compensator body is solved through the arrangement of the scouring protection device, a negative pressure ring is additionally arranged on the trough of the inner cavity of
