Problems solved by technology

However, the specific heat capacity of gas is generally small, and a large amount of cooling air must be consumed in order to cool high-temperature materials. On the one hand, due to the large cooling area, the cooling operation infrastructure and operating costs are high; on the other hand, the dust-laden flue gas after heat exchange It must be dust-removed bef

Abstract

The invention discloses a cooling device for a high-temperature powdery material. The cooling device comprises a cooling bin, a spiral cooling machine and a stirring barrel, wherein a feeding openingof the spiral cooling machine is connected with a discharging opening of the cooling bin; a discharging opening of the spiral cooling machine is connected with a feeding opening of the stirring barrel; a bin cooling water jacket is arranged on the outer wall of the cooling bin, a spiral cooling water jacket is arranged on the outer wall of the spiral cooling machine, and a spiral reamer is arranged inside the spiral cooling machine. The cooling device can cool the high-temperature powdery material and recycle waste heat for effective utilization, combines liquid-solid direct heat exchange andindirect heat exchange mutually, is high in heat exchange efficiency, low in operation cost and device cost, stable in operation, capable of saving energy, environmentally friendly and high in adaptability, and has great significance in cooling of the high-temperature powdery material and waste heat utilization. The invention further discloses a using method of the cooling device. The using methodhas the advantages of being easy to operate, low in operation cost, easy to maintain, green and environmentally friendly.

Description

technical field [0001] The invention relates to the fields of ore dressing, metallurgy and environmental protection, in particular to a cooling device for high-temperature powdery materials and a method for using the device. Background technique [0002] my country's ferrous metal mineral resources such as iron ore and manganese ore are relatively poor in endowment, and have the characteristics of "poor", "fine", "miscellaneous" and "scattered". According to USGS statistics, the average grade of iron ore in the world is 48.82%, while the average grade of iron ore in China is only 34.29%, which is far lower than the world average; lean ore accounts for a large proportion, and more than 95% of iron ore resources need to be enriched through beneficiation. It can be economically and rationally developed and utilized, of which limonite, siderite and mixed iron ore account for about 18%. A large number of laboratory tests and production practices have shown that magnetization roast...
