Description

Technical Field

[0001] The present invention relates to the field of protective equipment, and particularly to a smoke hood for preventing thermal deformation of a sintering annular cooler. Background Art

[0002] After the annular cooler cools the sintered ore, its hot waste gas is recovered and used for power generation through a waste heat utilization system, which is a relatively mature energy-saving and consumption-reducing measure at present. During the process of treating the flue gas, since the flue gas has heat, it is necessary to collect the flue gas. Currently, multiple angle steel bars welded vertically and horizontally are used as support means to prevent deformation inside the smoke hood, and the heat-insulating material is arranged on the outer surface of the smoke hood. However, during the collection process, since the smoke hood is located above the trolley of the annular cooler and is affected by the high-temperature working condition of 400 - 500 °C for a long time, the internal angle steel support structure often shows phenomena such as welding cracks and falling off due to thermal expansion deformation. The surface of the steel structure of the inner box of the smoke hood has no refractory insulation protection and is constantly scoured by the dusty hot flue gas for a long time, resulting in a reduced service life, deformation of the smoke hood, reduced sealing performance, and a decline in the collection efficiency of hot waste gas. At the same time, the deformation of the smoke hood will interfere with the rotating body of the annular cooler, thus easily causing equipment failures. Summary of the Invention
