Abstract

The invention relates to a vertical sinter cooler. The cooler comprises a bin (1), a feeding pipe (2), a cooling tower (4), a distributor (3), a separation type barrel (5), fans (6.2), a discharging device (6) and a discharging collection segment (7). The bin (1) is connected with the top end of the cooling tower (4) through the feeding pipe (2). The distributor (3) and the separation type barrel(5) are mounted in the cooling tower (4). The bottom of the cooling tower (4) is connected with the discharging collection segment (7) through the discharging device (6). A hot air outlet (8) is arranged at the upper end of the cooling tower (4). The interior of the cooling tower (4) is divided by the separation type barrel (5) into multiple independent spaces. The corresponding fan (6.2), a temperature detection device (6.1) and a distributed gate (6.4) are mounted at the bottom of each independent space. The discharging collection segment (7) is arranged at the lower ends of the distributedgates (6.4), and cooled sinter is collected. The occupied area of the cooler is small, and cost is reduced.

Description

technical field [0001] The invention relates to a vertical sinter cooler, which belongs to the fields of ironmaking and environmental protection. [0002] technical background [0003] The iron and steel industry is an important basic industry and a pillar industry of the national economy in my country. However, during the rapid development of my country's iron and steel industry, problems such as resource shortage and high energy consumption have emerged. Among them, high energy consumption has become one of the main problems restricting my country's iron and steel industry from participating in international competition, and the situation of energy conservation in the iron and steel industry is very severe. Among the many processes of steel production, the energy consumption of the sintering process accounts for about 11% of the total energy consumption of steel production. Therefore, the utilization of waste heat in the sintering process is very important to reduce energ...
