Project Name: China Nonferrous Metals Group Daye Nonferrous environmental protection comprehensive treatment project
End of 2015
Long term strategic cooperation
1. The operation of the flue gas dust removal and desulfurization system of the smelting branch is unstable; 2. The treatment of desulfurization wastewater produced by desulfurization and the high treatment cost; 3. The total cost of environmental flue gas treatment in the copper smelting process of China color Daye branch is about 60-74 million yuan / year.
Technical scheme for comprehensive treatment of environmental protection flue gas and industrial chain of derivative products production
Technical scheme for comprehensive treatment of environmental protection flue gas and industrial chain of derivative products production
1. In 2016, complete the transformation of equipment and process to achieve production capacity; 2. From 2017 to 2018, technological transformation and product diversification and high-quality production; The annual output of 100000 tons of sodium sulfite production system, 20000 tons of sodium pyrosulfite production system and 80000 tons of desulfurization wastewater treatment system have been built;
The flue gas is discharged up to the standard, and the so ν in the discharged flue gas is controlled at 50mg / m ³、 The dust shall be controlled at 10mg / m ³, Desulfurization efficiency reaches more than 97%; 40000 tons of sodium sulfite products with quality above 96.0%; Reduce the cost of desulfurization wastewater treatment; The comprehensive flue gas treatment cost is 27.5 million yuan a year, which is lower than the original treatment cost.
Project Name: environmental protection flue gas treatment project of Jiangxi Liwen company
Long term strategic cooperation
Kaiyi environmental protection company receives and processes the sodium alkali desulfurization waste liquid of Jiangxi Liwen company free of charge.
10000 tons of desulfurization waste liquid are received and treated every year, which solves the problem of environmental protection waste liquid treatment of flue gas desulfurization system of Jiangxi Liwen company, avoids secondary pollution, and greatly reduces the waste water treatment cost of Jiangxi Liwen company.
Project Name: environmental protection flue gas treatment project of Jiangxi Liwen company
Long term strategic cooperation
In 2019, Anhui Tongling Nonferrous Metals Group Co., Ltd. signed the cooperation agreement on sulfur resource product upgrading and comprehensive environmental protection treatment project
The cooperative flue gas is 1 million tons, and the base construction covers an area of 140 mu. At present, it is planned to complete the comprehensive treatment of 400000 tons of smelting flue gas and environmental protection in the first phase. The company has carried out preliminary due diligence and data collection for its project. The product R & D department is carrying out product R & D according to the content of flue gas elements. The project is currently recruiting strategic partners.
Project Name: sulfur containing flue gas treatment project for comprehensive utilization of tailings and waste residue of Wuxue Xinhe abrasive company
Long term strategic cooperation
1. The operation cost of sulfur-containing flue gas desulfurization is high in the process of pyrolytic melting of iron and sulfur rich tailings and waste slag; 2. Lack of supporting liquid disposal system after desulfurization, resulting in high secondary treatment cost of liquid after desulfurization, which directly affects the normal operation of tailings waste residue pyrometallurgical disposal system;
Comprehensive utilization of tailings and waste residue and treatment of sulfur-containing flue gas
1. Carry out process adjustment and local equipment transformation for the company's original sulfur-containing flue gas environmental protection treatment system to improve the quality of liquid after desulfurization; 2. Receiving the desulfurized liquid, processing and producing refined basic chemical products to realize the comprehensive utilization of sulfur resources;
60000 tons of desulfurized liquid are received and disposed every year, and 15000 tons of products are comprehensively utilized to produce economic benefits of 45 million yuan, which completely solves the hidden danger of environmental protection and flue gas treatment of tailing and waste residue production system of Wuxue Xinhe abrasive company.
Project Name: Green double carbon circular economy industrial park project
The total investment of the project is 650 million yuan, covering an area of 150 mu. The project will recycle SO2 and CO2, desulfurization wastewater and solid waste (sulfate) in the waste gas of smelting enterprises such as Hongsheng copper, Youke precision manufacturing and Xinxing pipe industry in Xingang Industrial Park, and produce basic inorganic salt products through various purification, separation and processing technologies.
After the completion of the project, the project can achieve an annual output value of 160 million yuan, a profit of 120 million yuan / year, an annual treatment of 500000 tons of waste sodium sulfate, a comprehensive treatment and utilization of 150000 tons / year of SO2 (flue gas) (converted into 98.3% sulfuric acid) and 250000 tons / year of CO2; At present, the project review and the signing of the investment cooperation agreement of the park have been preliminarily completed.
