Description

Technical Field

[0001] The utility model relates to the technical field of waste heat recovery, in particular to a waste heat recovery device for cooling a vertical cooling kiln frame. Background Art

[0002] The sintering process is a process in which various powdered materials, flux and fine coke are mixed and granulated, and then placed in a sintering machine to complete the sintering reaction, so that the powdered materials are transformed into block materials. The sintered ore needs to be cooled before entering the next process after sintering, and the waste heat of the sintered ore can be recovered for effective utilization. The vertical cooling kiln is a device for cooling sintered ore and recovering waste heat. The overall heat exchange process in the vertical cooling kiln is countercurrent heat exchange. The sintered ore particles are input from the material tank into the kiln body from above, and after buffering, they enter the cooling chamber and exchange heat with the cold air. After being discharged from the bottom of the kiln body through the discharge device, subsequent processing is carried out. The cooling air enters from the bottom of the kiln body, and the temperature rises after absorbing the heat of the sintered ore in the cooling chamber. The hot air gathers and is discharged above the kiln body for subsequent heat utilization.

[0003] During use, heat from the existing vertical cooling kiln will be transferred to the frame, resulting in a high frame temperature. In order to improve the stability of the vertical cooling kiln frame structure, the vertical cooling kiln frame needs to be cooled. However, the cooling equipment fixed on the vertical cooling kiln frame has a complex structure, which is inconvenient for rapid disassembly and assembly, and the waste heat on the frame cannot be recovered. To solve the above problems, the present application proposes a waste heat recovery device for cooling the vertical cooling kiln frame. Utility Model Content
