Industrial continuous production method and apparatus for tetrahydrofurfuryl alcohol diethyl ether

The present invention relates to an industrial continuous production method for tetrahydrofurfuryl alcohol diethyl ether. The method comprises the following steps: mixing tetrahydrofurfuryl alcohol and ethanol according to a specific ratio at first; then continuously transporting the mixture into a pipe reactor filled with a solid super acid catalyst; dehydrating and drying a crude product after reaction; and then rectifying the dehydrated crude product to obtain tetrahydrofurfuryl alcohol diethyl ether fractions. The present invention further relates to an industrial continuous production apparatus for the tetrahydrofurfuryl alcohol diethyl ether. The technical scheme provided by the present invention is suitable for industrial continuous production; the pipe reactor filled with the super acid solid catalyst is used, and the step of adding a super acid solution is omitted, danger factors of a production technique is eliminated, pollution emission in the production process is reduced, and production costs are effectively reduced; the whole production process is simple, the conversion rate is high, the operation is stable, and the product properties are excellent; and the method and apparatus are applicable to the production process of organic chemical ether compounds.
