Biomass continuous depolymerization device and method capable of taking materials on line

[0109] Such as figure 1 As shown, a biomass continuous depolymerization device capable of online reclaiming includes a pressurized feeding system, a reaction system, an online reclaiming system, and a reactant collector. Specifically include: reciprocating pressurized feeding system 1, equal pitch screw (first screw) 2, horizontal reactor (first reactor) 3, variable pitch hollow screw (second screw) 4, vertical reactor ( Second reactor) 5, catalyst feed port 6, hydrolyzate outlet 7, solid sampling port 8, sensor 9, residue outlet 10, power motor (power unit) 11.

[0110] Taking corn stalks as raw materials as an example, the crushed corn stalks are transported to the horizontal reactor 3 through the reciprocating pressurized feeding system 1, and at the same time, the high-temperature steam carries the acid liquid through the catalyst feed port 6 and the equal-pitch screw 2 to enter the reaction. Mix with the solid material in the container, and push it under the push of equal-p
