The invention discloses a method and device for preparing a melamine-based porous material. The method for preparing the melamine-based porous material includes step 1 of adding 50-60 parts of melamine, 30-40 parts of diaminodiphenylmethane, 20-50 parts of paraformaldehyde and 20-90 parts of deionized water, adjusting the pH to 9-11, and performing reflux reaction; step 2 of filling a closed container with inert gas, adding 15-25 parts of toluene and 10-30 parts of n-butanol, heating to 300 DEG C to 340 DEG C; step 3 of conveying the product in step 1 into the closed container, and evenly adding modifier and phase transfer catalyst in the conveying process; step 4 of heating the closed container to 500-540 DEG C to obtain a polymer prepolymer; step 5 of performing constant temperature carbonization of the polymer prepolymer; and step 6 of obtaining the melamine-based porous material after the carbonization and calcination. The method and device for preparing the melamine-based porous material has the advantag
