The invention discloses a multi-angle multi-surface multi-layer 360-degree air-supplying sinter ore cooling tower and belongs to the technical field of sintering equipment for iron making. The multi-angle multi-surface multi-layer 360-degree air-supplying sinter ore cooling tower is used for cooling sinter ores and recycling heat energy and consists of a feeding skew bridge, a distribution dust and waste air collection chamber, a dust collecting pipeline, a distributing device, a high-temperature heat energy recycling system, a boiler circulating air reutilization system, a medium-temperature cooling recycling system, a low-temperature cooling system and an unloading system. The sinter ores are uniformly packed into the cooling tower via the feeding skew bridge by a distributor; the high-temperature heat energy recycling system is used for sending utilizable hot air to a boiler; circulating air of the boiler is returned to a high-temperature section of the boiler by the boiler circulating air reutilization system so as to cool the sinter ores; cooling fans are uniformly mounted at a low-temperature section in the cooling tower in a layered way so as to cool the sinter ores; air vents and ventilating pipelines are respectively arranged at a medium-temperature section and the low-temperature section to realize flowing of cooling air inside the tower so that the sinter ores can be cooled. The multi-angle multi-surface multi-layer 360-degree air-supplying sinter ore cooling tower disclosed by the invention has the characteristics of being small in floor area, near in wind run, free of wind loss, high in wind utilization rate, high in heat energy collection rate, good in cooling effect and free of dust diffusion.
Description
technical field [0001] The invention relates to a multi-angle, multi-face and multi-layer 360-degree air-supply sinter cooling tower system, which belongs to the technical field of ironmaking and sintering equipment. Background technique [0002] In iron and steel production enterprises, sintering is one of the ironmaking production processes. The process is to mix powdered ore powder and coke powder, and then pass them through a sintering machine to make them into particles of a certain size to facilitate smelting. The sintered ore passing through the sintering machine needs to be cooled, and the cooling is mainly realized by the air cooling equipment below. At present, the sinter cooling equipment used by iron and steel enterprises has two forms: belt cooler and ring cooler. However, due to the constraints of the production site area, some enterprises cannot use belt cooler and ring cooler, and cannot realize heat recovery and environmental protection. In order to achieve...
