Description

Technical Field

[0001] The utility model relates to a rotary chassis of a fixed-axis type annular cooler. Background Art

[0002] Annular coolers are annular furnaces used to process industrial raw materials such as steel, usually using fixed-axis rotary chassis technology. The background of this technology stems from the continuous improvement of high efficiency, low energy consumption and environmental protection requirements. The advantages of fixed-axis rotary chassis technology are its simple structure, stable operation, easy maintenance, and ability to withstand high temperatures and high loads, suitable for large-scale continuous production.

[0003] Annular coolers play an important role in the steel industry, mainly used to cool sintered materials after crushing. They cool the materials through a blower and discharge high-temperature flue gas at the same time. The waste heat boiler of the annular cooler recovers this part of the high-temperature flue gas, and uses the high-temperature flue gas discharged after heat exchange to generate high-pressure steam, which in turn drives the steam turbine generator set to connect to the grid for power generation. This not only avoids energy waste, but also reduces exhaust gas emissions and improves economic benefits.

[0004] At present, the steel industry is facing the challenges of energy consumption and environmental pressure, so it is necessary to continuously improve and perfect the technology and equipment of the ring cooler. In the future, the ring cooler will pay more attention to energy saving and emission reduction, improving production efficiency and reducing production costs. At the same time, with the development of intelligent technology, the ring cooler will gradually realize intelligent control and remote monitoring, further improving the automation level of the production process.
