[0002] Ethyl vinyl ether is an important chemical product, widely used in coatings, inks, glues, resins and other fields. The reactor is a container for chemical reactions in the catalytic production process. In the reactor, raw materials such as ethylene and ethanol react with catalysts to generate ethyl vinyl ether. The reactor is usually resistant to high temperatures and corrosion to adapt to the high temperatures and corrosive conditions that may exist during the reaction process. The reactor then uses a stirring rod to evenly mix the reactants to promote collisions between reactant molecules and increase the reaction rate.

[0003] When vinyl ethyl ether is produced, the raw material of vinyl ethyl ether needs to be fed into the reactor through the feed pipe of the reactor. At this time, the staff needs to start the driving motor of the reactor to make the output shaft of the reactor drive the stirring rod to rotate, so as to accelerate the reaction of the raw materials of ethylene and ethanol and the catalyst. Since the general stirring rod is usually only stirred in the horizontal direction, it is easy to cause the raw materials of ethylene and ethanol and the catalyst to produce unevenness in the vertical direction. Therefore, we propose a reaction device for catalytic production of vinyl ethyl ether. Utility Model Content
