Core technology and equipment of the company (3)
Technical process package 3:high arsenic hazardous waste treatment,recovery and comprehensive disposal of arsenic containing hazardous waste from copper smelting
-
Core technology:
Transformation of arsenic containing hazardous waste-arsenic compounds-metal arsenic-rigid landfill
-
Technology combination:
white smoke selective arsenic removal technology,arsenic filter cake self reduction and sulfur recycling technology,oxygen enriched side blowing smelting technology of complex lead containing copper and arsenic materials,arsenic containing flue gas quench arsenic removal technology,clean purification technology of crude arsenic trioxide,reduction of calcium arsenate to prepare metal arsenic,etc.to form a treatment technology package for smelting arsenic containing materials,and output the arsenic in the materials in the form of arsenic oxide and metal arsenic products.
-
Competitive advantage:
-
Broaden the raw materials into the furnace.The chemical properties of arsenic are relatively active and seriously dispersed in the smelting process,which will lead to arsenic pollution in the whole system.Therefore,the smelting enterprises have strict control over the raw materials and prevent the materials with high arsenic content from entering the furnace.The oxygen enriched side blowing smelting technology of complex lead containing copper and arsenic materials developed by Ruiyi can greatly improve the arsenic content of the materials entering the furnace;
-
For directional separation of arsenic,the company adopts wet and fire treatment technologies according to the presence of arsenic content and other valuable metals,which can realize efficient directional separation of arsenic and avoid the whole process pollution of arsenic;
-
For the commercialization of arsenic,the arsenic in the material is finally produced in the form of arsenic trioxide and metal arsenic.There is a certain market.It can also be treated by rigid landfill.The arsenic is enriched by 5-20 times,and the reduction effect is obvious;
-
Comprehensive recovery:many arsenic containing materials also contain precious valuable metals such as copper,lead,precious metals and rare metals.If the problem of arsenic is not solved,the recovery will not be realized.It is also because of the existence of arsenic,the raw material price is relatively cheap,so dealing with the problem of arsenic can realize the high income of valuable metal recovery;
-
Environment friendly,sharp and targeted development of arsenic purification furnace,closed reduction furnace and other equipment.Compared with the traditional equipment,the treatment process of flue gas is scattered and the operating environment is very bad,so as to realize closed reduction and unorganized emission.
