The present utility model discloses a vertically distributed multi-stage twin-screw extruder, comprising a plurality of twin-screw extruders and a barrel support. Each twin-screw extruder comprises a driving device, two intermeshing and driving screws and a barrel; the two screws are in driving connection with the driving device and are rotatably inserted into the barrel, and the barrel is respectively provided with a feeding port, a discharging port and/or a liquid feeding port. The plurality of twin-screw extruders are distributed in a vertical direction, the driving devices of the plurality of twin-screw extruders are vertically stacked and connected with each other, the barrels of the plurality of twin-screw extruders are sequentially arranged on the barrel support in a vertical direction, and the discharging port of the barrel of each twin-screw extruder is connected with the feeding port of the barrel of the adjacent twin-screw extruder to form a multi-stage arranged twin-screw extruder. The present invention has a long total length-diameter ratio of the screws and a small floor area, can increase the material flow space and improve the material output quality.
