A method for cooling waste incineration ash, characterized in that: The method is based on a waste incineration ash cooling device according to any one of claims 1 to 9, comprising: The heat exchanger (2) delivers the cooling liquid for absorbing heat into the inlet pipe (30) of the mixing tank (5) through the double-branch rotary joint (38), so that the cooling liquid fills the entire hollow column (29) and the cavity (28), thereby increasing the contact area with the ash in the mixing tank; The stirring mechanism rotates, and stirs the ash in the stirring tank up and down, thereby stirring the ash in the stirring tank longitudinally and transversely, accelerating the flow of the ash, thereby improving the heat transfer ratio and accelerating the cooling speed.
