Abstract

The invention discloses a waste incineration slag treatment system and method. The waste incineration slag treatment system comprises an iron recovery system, a copper recovery system, an aluminum recovery system, a sand making system and a tailing treatment system. Compared with the prior art, in the waste incineration slag treatment process, through multiple times of crushing, grading and sorting, different metal objects are separately recycled according to different particle sizes, the recycling efficiency is high, the impurity removal rate is high, the sand making purity is high, and the economic effect is remarkable; and meanwhile, the treatment process belongs to a wet process, a large amount of water needs to be used, all procedures are closely connected, water resources are recycled in the process flow, meanwhile, a settling vat and a filter press are additionally arranged, the water resources are effectively recycled, water is saved, the environment is protected, and efficient utilization of energy is achieved.

Description

technical field [0001] The invention relates to the field of metal recycling, in particular to a waste incineration slag processing system and method. Background technique [0002] With the continuous enhancement of people's awareness of environmental protection and the improvement of comprehensive resource utilization technology, the proportion of domestic waste treated by incineration technology in various countries in the world is increasing year by year, and the production of slag is also increasing. This puts forward how to better deal with slag. higher requirements. [0003] The slag after waste incineration is an associated by-product of the domestic waste incineration process. It is mainly composed of ceramics, stones, slag, glass, scrap metal and unburned combustibles. It is used in many fields such as municipal transportation (such as unburned bricks, permeable bricks, backfill materials), construction engineering (such as recycled concrete), and the mixed metals ...
