The new edition of "Entry Requirements for Copper Smelting Industry" has begun to publicly solicit opinions. The opinion draft shows that the access conditions are regulated in terms of enterprise layout, production scale, external conditions, energy consumption, comprehensive utilization of resources, and environmental protection. It stipulates that the newly-built and reconstructed copper smelting and single-process copper copper recycling enterprises should have a single-system smelting capacity of 100,000 tons/year and above; and gradually phase out 50,000 tons/year of single-produced copper copper production enterprises. The opinion draft pointed out that the implementation of external conditions such as copper concentrate, scrap copper, transportation, etc., the proportion of self-owned raw materials should reach more than 30%, or the raw materials and raw materials obtained through joint venture and cooperation for more than 5 years can reach the total demand. More than 50%; encourage large and medium-sized copper smelting enterprises to deal with waste copper; the existing single-generation production scale of reclaimed copper enterprises should not be less than 50,000 tons/year, and phase out 50,000 tons/year of single-production cathode copper Recycled copper production company.
In terms of energy consumption, the access conditions suggest that the comprehensive energy consumption of the crude copper smelting process of the new copper smelting enterprise is 180 kg of standard coal/ton or less, and the comprehensive energy consumption of the electrolysis process (including electrolyte purification) is 100 kg of standard coal/ton and Below, the copper smelting process has a comprehensive energy consumption of 300 kg of standard coal/ton and below; the existing copper smelting enterprise's crude copper smelting process has a comprehensive energy consumption of 330 kg of standard coal/ton and below.
These standards are higher than the entry standards of the copper smelting industry in 2006. The access conditions in 2006 require that the comprehensive crude copper smelting process has a comprehensive energy consumption of 550 kg of standard coal/ton or less, and the existing crude copper smelting comprehensive energy consumption standard of 900 kg. Coal / ton or less.
In addition, the new access standards are more stringent in terms of the comprehensive utilization of resources than the old ones. The new version of access conditions is clear, the new copper smelting enterprise covers an area of ​​less than 4 square meters / ton of copper, water recycling rate of 97.5% or more, tons of copper new water consumption of less than 20 tons, copper smelting sulfur total capture rate of more than 99% The recovery rate of sulfur is over 97.5%, the drainage of tons of copper is less than 2 tons, and the wastewater containing heavy metal from copper smelting must meet the standard discharge.
Double Wall Corrugated Pipe is a kind of thermoplastic resin material; New material double wall Corrugated Pipe has very good mechanical properties, tensile strength around 60 mpa. In the process of pipe to add a few auxiliary agent can make the PVC pipe with flame retardant, acid and alkali resistant, wear resistant performance, and the most important for threading pipe insulation. These excellent features make burying double wall corrugated pipe occupied large market.
