Double-auger embedded pyrolytic reaction device

A double-auger embedded pyrolytic reaction device belongs to the technical field of biomass thermal cracking and mainly comprises a barrel wall, an auger transmission shaft, auger spiral blades, a hearth, a gas nozzle, a feed hopper, a carbon storage box, a motor and the like. According to the utility model, two sets of auger blades with opposite spiral directions are designed, and the interior of the auger transmission shaft is designed into a hollow area to serve as a hearth, so that the transmission shaft and the blades are changed into a high-temperature pyrolysis reactor, the high-temperature pyrolysis reactor has two functions of conveying materials and transferring heat, and the constraint that a single auger can only run at a low rotating speed in the traditional pyrolysis is eliminated; and rapid reciprocating operation of materials is realized, so that the contact opportunities of the materials with the high-temperature spiral blade and the transmission shaft are greatly increased, and the pyrolysis
