Abstract
The invention relates to a polyether polyol production device which comprises a kettle body, a motor mounted above the kettle body and a stirring shaft connected with the motor, the stirring shaft extends into the kettle body, a stirring paddle is mounted at the bottom of the stirring shaft, a liquid raw material feeding pipeline is arranged at the top of one side of the kettle body, and a liquid raw material discharging pipeline is arranged at the top of the other side of the kettle body. A discharge port is formed in the bottom of the reaction kettle and is connected with a feed port of the circulating pump, a discharge port of the circulating pump is connected with a feed port in the top of the mixing reactor, a discharge port in the bottom of the mixing reactor is connected with the reaction kettle body, and the reaction kettle is provided with a gas phase pipe which is connected with a gas phase gas inlet of the mixing reactor. Meanwhile, a discharge hole of the mixing reactor feeding pipeline is lower than the horizontal height of an air inlet.
