High-quality polyether polyol production and preparation system and method

The invention discloses a high-quality polyether polyol production and preparation system and method, and belongs to the technical field of polyether polyol production.The system comprises a reaction kettle, a control center is fixedly installed on the outer wall of the reaction kettle, a stirring mechanism is fixedly installed at the upper end of the reaction kettle, and a spraying mechanism is fixedly installed in the upper end of the reaction kettle; the device comprises a reaction kettle, an anaerobic mechanism is fixedly sleeved outside the reaction kettle, a plurality of feeding mechanisms are fixedly arranged on the anaerobic mechanism in a circumferential manner, the preparation of polyether polyol generally relates to an organic reaction, and oxygen can generate side reaction with reactants, so that the purity and the quality of a product are influenced, and in addition, the preparation of polyether polyol is not influenced. The oxygen may cause the safety problems such as combustion or explosion in
