But in the process of rapid development of the steel industry in China, the problems of resource shortage, high energy consumption and the like occur. Among them, high energy consumption has become one of the main problems restricting the iron and steel industry in our country to participate in international competition, and the iron and steel industry has a very severe energy-saving situation. In many processes of steel production, the energy consumption of a sintering process accounts for about 11% of the total energy consumption of steel production. Therefore, the use of waste heat from the sintering process is important to reduce energy consumption. Two parts of waste heat exist in the sintering process, one part is the waste heat of flue gas in the sintering process, and the other part is the sensible heat of the sintering ore after sintering is finished, wherein the sensible heat of the sintering ore accounts for about 70% of the resource of the sintering waste heat. Therefore, the recovery and utilization of sensible heat of the sintered ore are the most important to the utilization of the waste heat in the sintering process.
At present, the recovery device for sensible heat of sintered ores at home and abroad is mainly a cooling machine which is mainly divided into three types, namely a belt type, a ring type and a disc type. Although the belt type and ring type cooling machines are widely applied to the field of utilization of waste heat resources of sintering ores, the belt type and ring type cooling machines have the disadvantages of low waste heat recovery efficiency and low quality of recovered air heat.
