Description

Technical Field

[0001] The utility model relates to the technical field of environmentally friendly hot splashing treatment of steel slag, in particular to a novel environmentally friendly hot splashing treatment device for converter steel slag. Background Art

[0002] Steel slag is a kind of solid waste that is inevitably produced in the process of converter steelmaking. As the national environmental protection policy becomes more and more stringent, the dusty smoke generated during the hot pouring production process of converter steel slag has a great pollution to the environment, which makes the sustainable development of steelmaking production face severe challenges. At present, the main treatment methods of converter steel slag include: hot stewing method, hot pouring method, etc. Although the hot stewing method can effectively dissolve free calcium oxide and magnesium oxide during use, it causes a large amount of metallic iron to be unable to separate from the slag, and some iron oxides are converted into iron oxide, resulting in low recovery rates of metallic iron and magnetic iron in the subsequent treatment, and the iron content in the steel slag tailings exceeds the standard and cannot be recycled in large quantities. The environmentally friendly hot pouring process of steel slag is in line with the national circular economy, sustainable development, and green development guidelines, and is in line with the relevant national industrial policies. It is an effective means to greatly improve the utilization rate of steel slag and the added value of products, and has significant environmental, economic and social benefits.

The utility model discloses a novel environmentally friendly hot splash treatment device for converter slag, including five hot splash pools, with walking tracks fixed on both sides of the hot splash pool, a mobile cover car at the top of the hot splash pool, a dust removal device fixed on the mobile cover car, the mobile cover car is slidably connected to the walking track, and five positioning devices are fixed on the walking track. The utility model uses a sealed steam exhaust and dust removal facility to seal the hot splash pool, collect the smoke and steam generated during the water pumping operation, and discharge them in compliance with the standards after condensation and dust removal equipment, thereby reducing pollution to the environment. Walking tracks are set on the side and in front of the hot splash pool, and the steam exhaust and dust removal facility uses a mobile device, and the mobile cover car is put into place to perform water pumping operations. At the same time, the steam exhaust facility pipeline is opened to connect the steam condensation and dust removal equipment at the rear, so that multiple hot splash pools can be easily processed.

[0004] The mobile cover truck is used to pump water, and the steam exhaust pipe is opened to connect the steam condensation and dust removal equipment. This can facilitate the treatment of multiple hot splash pools. However, there is no dust collection and filtering device when collecting flue gas and steam dust, which makes the dust removal effect poor.
