The invention discloses a roller type biomass and waste pyrolysis gasification incinerator, which includes a broken material pyrolysis gasification cylinder, a broken material pyrolysis gasification cylinder driving device and an incinerator body, the broken material pyrolysis gasification cylinder is arranged obliquely, broken nails are distributed on the inner wall of the broken material pyrolysis gasification cylinder, and the broken material pyrolysis gasification cylinder driving device is connected with the broken material pyrolysis gasification cylinder in a transmission mode, and usedfor driving the broken material pyrolysis gasification cylinder to rotate along the axis of the cylinder; and an opening and a material incineration platform are arranged on the incinerator body, theopening is formed in the furnace wall of the incinerator body, and the material incineration platform is arranged in the incinerator body below the opening. By arranging the broken material pyrolysisgasification cylinder, the broken material pyrolysis gasification cylinder driving device drives the broken material pyrolysis gasification cylinder to rotate in the axis direction, under twist-puncturing of the broken nails, materials in the cylinder is broken, in the process of breaking, hot air in the incinerator conduct drying pyrolysis treatment on the materials in the cylinder, the materialscan be exposed to the hot air due to the constant turnover state of the materials in the cylinder, material accumulation is avoided, the efficiency of drying pyrolysis gasification is improved, the operation steps are simplified, the operation difficulty is lowered, and the treatment cost of the materials is lowered.
