The utility model relates to the technical field of polyether polyol, in particular to a circular reaction device of polyether polyol, which comprises a tank body, a liquid inlet is arranged at the upper end of the tank body, an air inlet is arranged at the lower end of the side wall of the tank body, a first one-way valve is arranged on the air inlet, and a second one-way valve is arranged on the first one-way valve. When the device is used, reaction liquid is firstly added through the liquid inlet, then gas raw materials are continuously added through the gas inlet, a reaction is carried out in the tank body, redundant gas can enter the barrel body through the gas outlet pipe, the gas raw materials are continuously added through the gas inlet, the gas raw materials are continuously added through the gas inlet, the reaction is carried out in the tank body, and the residual gas can enter the barrel body through the gas outlet pipe. The piston is repeatedly pushed through the electric telescopic rod, the pisto
