Recently, the energy-saving technology upgrade for the concentrate drying system of Jinlong Copper Company has been fully carried out. The steam drying of waste heat is used instead of the original air-flow drying system, which saves both cost and environmental protection. After the transformation, the company’s cathode copper consumption will be reduced to 212.7 kg of standard coal per ton of copper, and the heavy oil consumption will be reduced by 4,080 tons. The flow of sulfur dioxide in the exhaust gas will be reduced by 273.06 tons, and the carbon dioxide emissions will be reduced by 14327.25 tons. The annual operating cost is also Will reduce 10.92 million yuan. After many years of scientific and technological research and technological transformation, the company has developed a dual rotary jet smelting technology and intelligent numerical control blowing process with independent intellectual property rights, which has opened up a new technology route for the development of copper smelting in China. Affected by the current economic environment, together with the sulfur dioxide content in the exhaust gas of the company's air drying system, it was designed and operated in accordance with the then national standard of 800 milligrams per cubic meter, sometimes failing to reach the national "copper, nickel and cobalt industry pollutant discharges. standard requirement. In order to further achieve energy saving and technology upgrading, the company invested more than 7700 million yuan to save energy and reduce consumption of concentrates and upgrade technology. The project began on May 25 and is scheduled to be completed around September 20th. Its core content is to replace the currently high energy-consuming air drying system with energy-saving and environmentally friendly steam drying. The project mainly includes the demolition of the original air-flow drying system, the establishment of a new steam drying system at the location of the original air-flow drying and electric dust collection, and the supporting transformation of the steam dryer feed system, the opening and exhaust smoke system, and the power center air compressor and low-pressure boiler room. Provides steam for start-up and compressed air for concentrate conveying for steam drying systems. The project responds to the national energy conservation and consumption reduction and technological upgrading industrial policies, and the effect of energy saving and emission reduction is very obvious. After the technical transformation, the company will completely solve the problem of overdraft exhaust gas sulfur dioxide emissions and reduce carbon dioxide emissions.
