Core technology and equipment of the company (1)
Technical process package 1:re oxygen enriched side blowing furnace for treatment of lead paste and smelting waste slag containing heavy metals
-
Core technology:
the overall design and manufacture of side blowing furnace to ensure the yield per unit area,the design of tuyere to ensure that there is no dead zone in the furnace,and supporting facilities such as furnace body cooling,waste heat and high sulfur flue gas treatment;
-
Technical process:
the lead paste and smelting waste slag(flue ash)are automatically proportioned according to the nature of raw materials and sent to the proprietary oxygen enriched side blowing furnace developed for different materials.By controlling the smelting parameters such as temperature,atmosphere and slag type,the reduction output of valuable metals is realized,the slag is harmless,and the standard emission of tail gas is realized through various flue gas treatment technologies.
-
Competitive advantage:
the national industrial policy mainly promotes the oxygen enriched side blowing furnace treatment technology,and there are many kinds of side blowing furnace treatment technologies.For reference,the smelting of primary lead adopts the configuration of oxidation furnace+reduction furnace,while the single furnace smelting technology developed by Ruiyi can be reduced in one step,reduce investment and operation costs,and maintain energy conservation and environmental protection.
