The invention relates to a vertical device of a sintered ore with an integrated flow grading utilization waste heat. The vertical device comprises a barrel body, a cross-shaped material distribution structure, an annular air distribution pipe, a cooling air opening air supply pipe, a cone body and a discharging hopper, wherein a feeding port is formed in an upper end of the barrel body, the cross-shaped material distribution structure is fixedly arranged below a right center of the feeding port, first hot air outlets are formed in two sides of the upper end of the cylinder body, a pre-storagesection and a cooling section are sequentially arranged below the first hot air outlets in the barrel body, and a second hot air outlet is formed in a 5/7 part of the bottom of the cooling section; and a cooling air inlet is formed in a bottom end of the cooling section and penetrates into the barrel body, the annular air distribution pipe is arranged on the cooling section and is tightly attachedto an inner wall of the barrel body, the discharging hopper is arranged at a lower end of the barrel body, a discharging port is formed below the discharging hopper, and the cone body is inserted ina center of an upper part of the discharging port. The integrated flow of the sintered ore can be effectively realized, the cooling efficiency is improved, the effective heat exchange space is increased, and heat grading recovery is realized.
