description The invention discloses a sludge incineration method. The sludge incineration method comprises the following steps that a, sludge is conveyed into an incineration region which is rotationally stirredby taking the vertical direction as an axis, the sludge is heated, the heating temperature of the sludge rises to be at least 200 DEG C, and water in the sludge is evaporated; b, VOCs in the sludge isevaporated at the temperature of 200-600 DEG C, and organic matters are pyrolyzed to form combustible gas, the surface of the sludge is always continuously updated by stirring and rotating, and the organic matters in the sludge are continuously heated and decomposed; c, carbonized substance is formed after the sludge is pyrolyzed, air is introduced into the incineration region in the radial direction to carry out primary oxygen supply, and the sludge is driven to move towards the center of the incineration region in the incineration process along a spiral shape, wherein the incineration temperature is 800 DEG C or bel
