Description

Technical Field

[0002] Ethylene glycol, also known as glycol, is the simplest diol. Ethylene glycol is a colorless, odorless, sweet-tasting liquid with low toxicity to animals. Ethylene glycol is miscible with water and acetone, but has a lower solubility in ethers. It is used as a solvent, antifreeze, and raw material for synthetic polyester, so a new type of ethylene glycol hydrogenation reactor is required. Hydrogenation reaction refers to the reaction process in which hydrogen interacts with other compounds, usually in the presence of a catalyst. In the process of ethylene glycol hydrogenation reaction, an ethylene glycol hydrogenation reactor is required.

[0003] A Chinese patent with the authorization publication number CN218784801U discloses an ethylene glycol liquid phase hydrogenation reactor, comprising a reaction tower, a water separation layer is arranged inside the reaction tower, a direct current channel for raw materials to circulate is arranged outside the water separation layer, a guide layer is arranged inside the water separation layer, the guide layer has an inclination angle arranged toward the direct current channel, a drainage component for limiting the flow direction of the raw materials is arranged outside the water separation layer, and the drainage component is vertically corresponding to the opening at the top of the reaction tower. The utility model drains the ethylene glycol liquid through the water separation layer, the water storage tank, the guide holes and the guide line groove, in conjunction with the inclined mesh plate and the water outlet hole, so that the ethylene glycol liquid can overflow from the gap of the water separation layer after filling the water storage tank, thereby achieving a large-area diffusion effect. At the same time, the ethylene glycol liquid remaining in the water storage tank can be discharged through the guide holes and the guide line groove under the drainage of the inclined mesh plate to avoid raw material residue.
