The invention relates to a reactor for preparing ethylene glycol through dimethyl oxalate hydrogenation. The reactor comprises a plurality of reaction tubes, wherein blind tubes (1) are arranged at parts requiring heat transfer intensification in the reaction tubes. Compared with the prior art, the reactor has the advantages that heat transfer is intensified, excessive reactions can be avoided, the design is simple, and radial and axial temperatures of a reactor bed layer are optimized. 本发明涉及种草酸二甲酯加氢制乙二醇用反应器，包括多根反应管，所述的反应管中在需要强化传热的部位设有盲管(1)。与现有技术相比，本发明具有强化了传热，避免了过度反应，设计简单，优化了反应器床层轴向和径向温度等优点。
