Specific embodiment
As shown in Figure 1, a kind of dimethoxymethane production device, including catalytic rectifying tower 12, methanol tank 1, formaldehyde tank 2, condenser
6, return tank 5 and connecting pipeline successively include: tower bottom section, gas-liquid separation inside the catalytic rectifying tower 12 from bottom to top
First wire packing section, catalyst filling section, the tower tray section of rectifying column are connected with that carry out liquid phase jointly for methanol and formaldehyde anti-
The fixed bed catalyst reactor answered, tower top section are connected with condenser 6, and tower top section passes through the condenser 6 being connected thereto and is connected to
Return tank 5, the fixed bed catalyst reactor of the tower tray section of the rectifying column 12 are the solid acid catalyst of upper layer and lower layer arrangement
Reactor, upper layer solid acid catalyst reactor 11 pass through formaldehyde intake pipeline 9 and formaldehyde with glass silk floss filter 3

Alcohol tank 1 connects, and is provided with exhaust-valve 7 at the top of return tank 5.
The device working principle is to be connected to two or more and each filling solid acid catalyst reactor
On single distillation column.Solution containing methanol, formaldehyde and water carries out solid~liquid with solid acid catalyst in the reactor respectively
Contact, catalysis generate dimethoxym ethane.Recycled from reactor come the solution containing methanol, formaldehyde, water and dimethoxym ethane again with steaming
Evaporate the steam in tower and carry out the contact of gas~liquid, the steam after contact again with destilling tower again compared with the solution recycled in higher order reaction device
Once carry out gas~liquid contact.As steam passes through this continuous gas~liquid contact tower grade, the dimethoxym ethane concentration in steam phase
It is stepped up.According to the method, the yield of the dimethoxym ethane of acquisition is calculated as 90% with formaldehyde charging.It is evaporated by overhead extraction acetal
Point, and be stored in product storage tank, unreacted formaldehyde and by-product water are discharged from the bottom of rectifying column.
