[0002] Polyether polyols are prepared by polyaddition reaction of initiators (compounds containing active hydrogen groups) with ethylene oxide (EO), propylene oxide (PO), butylene oxide (BO), etc. in the presence of a catalyst. Polyether polyol series products are mainly used to prepare rigid polyurethane foam plastics and are widely used in refrigerators, freezers, refrigerated trucks, insulation boards, pipe insulation and other fields. The obtained products have low thermal conductivity and good dimensional stability, and are also important raw materials for preparing composite polyethers. The existing reactors for the production of polyether polyols generally have unreasonable agitator settings, making it difficult to fully and evenly mix multiple materials, resulting in substandard polyether polyols after production, which greatly reduces the practicality of the reactor. In view of this, we propose a reaction device for the production of polyether polyols.
