Problems solved by technology

However, the output of the sintering machine per unit time is much larger than that of the coke oven, so the single-tank structure adopted by the CDQ furnace is difficult to cool the sinter
The reason is that the capacity limit of the single-tank structure cannot meet the huge output requirements of the sintering machine

Abstract

The invention discloses a mobile tank type cooler. The cooler comprises: 1) a ring slot shaped cooling bin, 2) a drive device for driving the ring slot shaped cooling bin to move, 3) a ring-shaped hotblast cover which is arranged on the ring-shaped cooling bin, 4) at least one hot air collecting tube which is connected with the top or the side part of the hot blast cover, 5) a cooling air duct which is arranged at the inner side of the ring slot shaped cooling bin, 6) a ring-shaped rotary rack which is arranged on the bottom of the ring slot shaped cooling bin and the bottom of the cooling air duct, 7) an ore discharge hopper which is arranged on the lower part of the ring slot shaped cooling bin, 8) a plurality of cooling fans, and 9) a cooling air communication tube which is arranged between the cooling air duct movable base and the ring-shaped rotary rack, wherein the cooling air duct comprises a cooling air duct movable base and a cooling air duct fixed cover; the ring-shaped rotary rack is hollow and is equipped with an air passing beam; and air outlets of the cooling fans communicate with the cooling air duct through corresponding air pipes. The mobile tank type cooler eliminates all air leaking links, guarantees good airtightess, and greatly increases waste heat recycling amount.

Description

technical field [0001] The invention belongs to the fields of ironmaking and environmental protection, and in particular relates to a mobile tank cooler and a sinter cooling method. Background technique [0002] Powdered iron ore concentrate powder must be agglomerated before entering the blast furnace. The sintering process is the main process for iron ore agglomeration in the iron and steel industry. The discharge temperature of the sintered ore is generally 600°C to 700°C. After cooling, the hot ore enters the raw material warehouse for standby, and the temperature of the cooled sintered ore does not exceed 150°C. Due to the huge output of sinter ore, the domestic annual iron production is calculated as 800 million tons, and the annual production of sinter ore exceeds 1.7 billion tons. It can be seen that the heat energy released during the cooling process of sinter ore is very considerable. [0003] At the end of the last century, with the development of technology and ...
