Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water slag treatment, in particular to a movable water slag steam collecting cover vehicle. Background Art
[0002] High-temperature liquid slag (1350-1500℃) is produced by smelting in water blast furnaces. As one of the main solid wastes generated by steel mills, its production volume is huge with the continuous development of the steel industry.
[0003] For a long time, slag-water separation has mainly adopted traditional bottom filtration process or mechanical process. How to complete slag granulation in the best way, handle the steam generated by the water slag flushing process and achieve efficient separation of slag-water mixture is of great significance to the green development of the steel industry and my country's circular economy. Many new and rebuilt blast furnace projects cannot use the traditional bottom filtration process with a large footprint due to site restrictions, and the mechanical process has the disadvantages of high investment cost and large maintenance workload. The market urgently needs a new water slag treatment process solution. In the face of these problems and needs, our design institute has explored and improved the defects of the traditional bottom filtration method based on years of water slag design practice, and formed an environmentally friendly bottom filtration water slag treatment system, which has been widely used in steel mills.
[0004] The biggest pollution of water-slag flushing is the large amount of water vapor emitted. The water-slag vapor emits pollutants such as S and P into the atmosphere, which seriously corrodes the surrounding facilities. In order to reduce the loss of water-slag vapor to production facilities, the conventional practice is to ensure the organized emission of water vapor. For the filter pool, a steam collection hood is designed at the point where the slag-water mixture falls in the water-slag ditch filter pool, and is connected to the chimney of the granulation tower to discharge the steam into the atmosphere in a centralized manner to ensure that there is no steam diffusion above the filter pool.
[0005] However, due to the large size of the steam collecting hood, this solution requires more lifting equipment and increases the workload of on-site operators due to the large size of the steam collecting hood. The steam collecting hood is often idle. Utility Model Content
