Abstract
The name of the invention is a controllable temperature cooling device of multitube in-tank slag, belonging to the field of metallurgy energy conservation. The device comprises a cold air chamber inlet pipe, a cold air chamber, a hot air chamber outlet pipe, a hot air chamber, a slag tank, cold air feeding pipes, hot air discharge pipes and slag. The controllable temperature cooling device of multitube in-tank slag is inserted in the slag tank. After entering the cold air chamber through the cold air chamber inlet pipe, the cold air is fed to 1-640 hot air discharge pipes that are matched with the feeding pipes respectively by 1-640 cold air feeding pipes so as to cool slag. The cold air is heated by the hot air discharge pipes into high-temperature hot air that then enters and gathers in the hot air chamber. Finally, the high temperature hot air flows from the hot air chamber outlet pipe to outside a hot air header for external use. The cold air takes the heat of slag away when flowing through the hot air discharge pipes. The quantity of exchanged heat is regulated by feeding cold air amount and air temperature.
Description
Technical field:
The present invention relates to slag temperature controllable refrigerating unit in a kind of multitube jar, belong to field of metallurgy.
Background technology:
High temperature scum, slag that smelter ironmaking both at home and abroad, steel-making at present produces are to abandon as refuse mostly, cause the massive losses of solid-state physics heat.Contain also in the high ferrotianium slag that Flos Bombacis Malabarici iron and steel group company outwells that 18% titanium elements is also abandoned and need not, financial loss is very big." selectivity is separated out " clean separation titanium technology of research and development is carried out experimental study in laboratory and semi-industrial scale recently, has obtained effect preferably, but can't carry out controlled slowly evenly cooling off and heat recuperation to high ferrotianium slag at present.
Summary of the invention:
In order to remedy the deficiencies in the prior art, the present invention will provide a kind of cooling rate of may command slag and slag temperature controllable refrigerating unit in the multitube jar that the physics heat that slag contained is used.For reaching this purpose, slag temperature controllable refrigerating unit should comprise that packaged air conditioner inlet tube, packaged air conditioner, hot bellows outlet pipe, hot bellows, slag ladle, cold wind sends into pipe, hot blast vent pipe and slag in the multitube jar.Slag temperature controllable refrigerating unit in the multitube jar is inserted in the slag ladle, and cold wind divides after the packaged air conditioner inlet tube enters packaged air conditioner to be sent into pipe by 1～640 cold wind and sends to send into cold wind and manage 1～640 hot blast vent pipe of paired, and slag is cooled off.Cold wind enters hot bellows and converges is heated to be high-temperature hot-air by high temperature furnace slag in hot blast vent pipe flow process after, and high-temperature hot-air promptly flows to the hot-blast main from the hot bellows outlet pipe and uses for extraneous.Cold wind is just taken away the heat of slag when flowing through the hot blast vent pipe, and what of heat exchange are controlled by the cold blast rate of sending into and cold wind temperature.
