[0002] The wastewater distillation recovery device for polyurethane elastomer production is a device specially designed to treat wastewater generated in the production process of polyurethane elastomers and recover useful substances through distillation technology. The device separates the water and organic matter in the wastewater through the distillation process, achieving wastewater purification and recovery of useful substances.

[0003] After the wastewater from the production of polyurethane elastomers enters the distillation recovery device, it is heated to form steam, in which the organic matter rises with the steam, and then condensed into liquid through the condenser to achieve the recovery of the organic matter. Through the distillation process, the harmful substances and organic matter in the wastewater from the production of polyurethane elastomers are separated to achieve the purpose of purifying the wastewater. However, some of the impurities produced after distillation are solid, and these solids will accumulate at the bottom of the distillation device. The solid impurities produced after distillation need to be properly treated to ensure compliance with environmental protection requirements and maximize resource utilization. However, the distillation device is generally well sealed, and it is more troublesome to clean up the solid impurities. Therefore, a wastewater recovery device for polyurethane elastomer production is needed to solve the above problems. Utility Model Content
