A few days ago, from the Lianshan District, Huludao City, Liaoning Province, it was learned at the on-site technical renovation of industrial kilns that six carbon companies in the region succeeded in renovating the traditional kiln-combustion chamber structure of industrial kilns to control dust pollution. It has provided new technical guarantees for the effective prevention and control of smoke and dust pollution and improvement of the atmospheric environment.
It is understood that this technology is to transform the structure of the traditional kiln-head combustion chamber of an industrial kiln, close the furnace body, use the residual heat to preheat the air supply, and not to enter the cold air, so that the coal can continuously and dynamically reach the fire. After the smoke, first dry distillation, after the combustion, burning out the coal volatiles, so as to achieve complete combustion of coal, thereby achieving the purpose of reducing pollution and reducing consumption. This technology can also be promoted in ceramics, refractory materials, molybdenum oxide and other industries.
At present, six carbon production companies in Lianshan District of Huludao City produce 45,600 tons of graphite electrodes and pre-baked anodes annually. Before the technical transformation, tons of raw coal consumes one ton of raw coal, and six carbon companies require a total of 45,600 tons of high-quality coal. The funds amounted to 14,590,200 yuan. After the technological transformation, the tons of products consumed 0.7 tons of raw coal, 6 carbon companies shared common carbon 29,640 tons, and the funds needed to purchase coal were 7,133.6 million yuan, which together saved 15,960 tons of coal, and saved coal equivalent to 7,478,400 yuan. . The six carbon companies created direct economic benefits from coal saving and electricity saving for the year of 9.14.60 million yuan, reducing 140.48 tons of soot emissions. At the same time, these six carbon companies have saved 20% of their man-hours in the kilns, which has reduced the labor intensity of workers and improved the labor environment of workers.
