Vertical high-temperature pyrolysis gasifier

The invention relates to the technical field of mechanical equipment, in particular to a vertical high-temperature pyrolysis gasifier. According to the vertical high-temperature pyrolysis gasifier, garbage is smashed, the smashed garbage is evenly scattered on flames in a gasifier body, the garbage can fully make contact with the flames conveniently, the incineration disposal effect of the garbageis improved, meanwhile, the shape of the garbage is reduced, the garbage is fully burnt conveniently, and the practicality and the reliability are improved. The vertical high-temperature pyrolysis gasifier comprises the gasifier body, a groove plate, four groups of supports, a first rotary shaft, four groups of push plates and a first motor. The groove plate is located on the upper side in the gasifier body and fixed to the inner wall of the gasifier body through the four groups of supports, and multiple groups of screen holes are uniformly formed in the bottom end of the inner wall of the groove plate in a communica
