Problems solved by technology

At present, the main cooling method is that the water wall is cooled and crushed by a crusher. The heat carried by the calcium carbide in the above process, especially the sensible heat, is inconvenient to recover, and this part of the heat is wasted; moreover, the cooling process is complicated and the efficiency is low.

Description

technical field [0001] The invention relates to a steel slag / carbide cooling and waste heat recovery system. Background technique [0002] At present, the main disposal methods of steel slag are hot pouring, water quenching, etc. The above-mentioned various steel slag treatment processes need to consume a lot of water, resulting in high cost of steel slag treatment; moreover, the heat carried by steel slag is inconvenient to recover, and this part of heat is wasted At the same time, the water vapor generated during the steel slag treatment process contains a large amount of alkaline dust, which will corrode the workshop roof, beams and other structures, which is also very harmful to the human body and pollute the atmosphere; moreover, due to the use of water cooling, the steel slag is further When using, the steel slag needs to be dried, which still consumes a lot of energy. [0003] In addition, the calcium carbide production process also needs to be cooled before crushing...
