Embodiment 1
[0170] The height of the tower body consisting of the top cover and the tower wall of the cooling machine is 9 meters. The outer diameter of the tower body is 13 meters. The diameter of the hood is 2.5 meters. The height of tower body cone 5 is 5.5 meters. The inner diameter of the wind ring is 10.5 meters.
[0171] The daily processing capacity of sinter is 8650 tons / day. The temperature of the sintered ore before entering the silo is 700°C, and the temperature of the hot air at the hot air outlet 8 reaches 500°C. The recovered heat is used to generate electricity, and the power generation is about 35 kWh.
[0172] Compared with the prior art annular cooler, the advantages are: high power generation, low air leakage rate, small dust emission, simple and reliable equipment, and because of better sealing, the technology of the present invention can provide higher temperature hot air for generating High-temperature steam significantly improves power generation efficiency.
