It is reported that all the economic and technical indicators of this 5,000-ton/year phosphoric acid process continuous activated carbon production line have all met the design requirements, with only 0.16 tons of ton of finished product carbon, which is 40% lower than the general domestic level, and the dust concentration is 2700mg from burning coal. The reduction of /m3 to 65 mg/m3 will reduce the emission of 240 tons of sulfur dioxide and other pollutants and save 12,000 tons of standard coal, which has completely changed the production status of domestic phosphoric acid wood activated carbon.
Lu Yuanjian, Chairman and Chief Engineer of Yuanli Company, told reporters that as early as 10 years ago, they had developed the first 1,000 tons converter wood activated carbon production process in China. Based on the new 5,000-ton continuous large-scale wood activated carbon production technology developed on this basis, combustible gas generated from the production of wood pellets is used instead of traditional fossil energy (coal) as fuel, so that the activated carbon production process is energy self-sufficient, and the production process does not consume energy ( coal). At the same time, the washing wastewater can also be recycled for recycling. They use quenching and tempering equipment and completely non-metal electrostatic precipitators to eliminate the impact of exhaust gas on the environment, so that the production process does not produce sulfur dioxide pollutants, no dust, waste water emissions, product adsorption power than traditional processes increase 20% to 30%, tons Reduce product costs by more than 20%.
At present, the project has passed provincial-level scientific and technological achievements appraisal, and has achieved energy-saving and emission reduction, as well as large-scale, automated and continuous production equipment.
According to reports, wood activated carbon with its unique strong adsorption function is widely used in petroleum and petrochemical, environmental protection, food and beverage, pharmaceutical purification and purification and water treatment and gas purification and other fields. Wood activated carbon production process can be divided into chemical and physical methods. At present, the domestic chemical method (phosphoric acid method) of wood activated carbon has the problems of large consumption of phosphoric acid, high energy consumption, serious smoke pollution, low degree of mechanization, and high labor intensity.
Phosphoric acid activated carbon has a clean process
In an interview with Fujian Yuanli Activated Carbon Co., Ltd. on November 27, the reporter saw that the company’s independently developed phosphoric acid activated carbon cleaner production process has achieved large-scale production, and the completed 5,000-ton device has achieved smooth operation with domestic production capacity. 5 times the current size. The new device has achieved remarkable results in energy conservation, emission reduction and consumption reduction.
