The invention discloses a method for continuously preparing cyclic ether compounds, according to the method, alcohol raw materials are used as raw materials to prepare the cyclic ether compounds through continuous dehydration reaction, and the catalyst applied to the method can stably operate for a long time. The preparation method of the cyclic ether compound comprises the following steps: 1, adding a catalyst into a continuous reactor, heating to a catalyst activation temperature of 300-500 DEG C, keeping for 1-6 hours, and adjusting to a reaction temperature of 160-450 DEG C; and 2, keeping the reaction pressure at 0.1-3 MPa, gasifying the alcohol raw material, and introducing the gasified alcohol raw material into the continuous reactor for reaction. According to the method for continuously preparing the cyclic ether compound, continuous production can be achieved, the efficiency is high, and the used catalyst is good in stability and long in service life. 本申请公开了一种连续制备环醚类化合物的方法，该方法以醇类原料为原料连续化脱水反应制备环醚类化合物，
