Description: Beijing with the international standards for the implementation of the DB11/139? 2002 "Integrated emission standard of pollutants in the boiler", and successfully developed a novel and effective water film spin disordered desulphurization and dust removal technology. It magnesia a water boiler slag or lime water in a boiler slag, or limestone water in a boiler slag, or biochemical desulfurization liquid to drain off water through water film, swirling, turbulent flow with combination of wet desulfurization dust removal equipment, with more investment in the province, lower operating costs, in total control, and meet strict Beijing "Integrated emission standard of pollutants in the boiler," and no secondary pollution, does not produce scaling, plugging, with water and so on. The desulphurization and dust removal technology, successfully used in 2002, Beijing University of Posts and Telecommunications (20t per h heating boilers), Beijing Yanjing Brewery Co., Ltd. (20t / h of industrial steam boilers), efflux of SO2 in flue gas is less than 30mg per m3 (session II, standard 150mg per m3), smoke less than 30mg per m3 (session II, the standard for the 50mg per m3). NOx is less than 180mg per m3 (the first time standard 300mg per m3). The new technology is being applied throughout the promotion.
1 Background Order to improve and enhance the quality of atmospheric environment in Beijing began in 1998 to control air pollution on emergency measures enacted in 2002 and international practice DB11/139? 2002 "Integrated emission standard of pollutants in the boiler," according to the standard , in particular, November 1, 2003 began the implementation of the first period II standards, the existing boilers, even with a large number of granite dust in the boiler water film, efflux of flue gas SO2, smoke and other pollutants can not be compliance.
For a lot of water film with a granite dust in the boiler, the efflux of gas to meet the criteria of the status quo, if the demolition or partial demolition to take all the way again on the FGD facility, not only large investment, but also creates a large number of difficult to deal with solid waste, to the enterprises, particularly the cash-strapped companies are difficult to accept. Currently, the best way is based on status, with more investment in the province, lower operating costs, to meet new and more stringent gas emission standards. Accordingly, the successful development of a novel and effective water film spin disordered desulphurization and dust removal technology, first in 2002 and Beijing University of Posts (20t per h heating boiler) was successfully applied, followed by the Beijing Yanjing Brewery Co., Ltd. (20t h of each industry steam boiler) was re-applied successfully.
2 flue gas desulphurization technology outlook
In view of the weak economic strength, environmental standards are increasingly linked to the world situation, we can not choose the industrial countries control the current environment of high input model, based on domestic, on their own, the study on investment, low operation cost, Domestic handling good effects flue gas desulfurization technology, is the only way to make business afford to go to, but also can afford, in our country only has a broad practical prospect.
Here are some of our recent good run effect of practical technology.
Cheng Zhi long Yanguang Jin, who invented two inventions patented technology, are both authorized the first "semi-dry flue gas desulfurization and production of magnetic fertilizer and equipment, integrated approach" (Certificate No.: 86 016 No.) the second, "flue gas treating coking residual ammonia or all of the coke water effluent" (Certificate No.: 84 133 number), two patents to solve the current problem of high cost of flue gas desulfurization, are semi-dry desulfurization technology, using patented technology is the special equipment, flue gas desulfurization and coking the high concentration of refractory organic integration of industrial waste water treatment, waste is waste control technology, not only to good effect and also has the investment, operation low-cost, zero emissions treated waste water, no secondary pollution, the advantage of, in 1999, first in Jiangsu Province, Huai Steel Group was successfully applied, and then in Shanxi Province, Taiyuan Iron and Steel Company Group Pro, the success of Laiwu Steel Group, Shandong Province application. Is currently in Sichuan, Henan, Hebei and other places to promote the application of generalization and application, but also the original patented technology has improved, improved technology, technical and economic advantages of larger, more practical.
In addition, the drain tray boiling layer of wet flue gas desulphurization technologies, swirling vortex sheet layer wet flue gas desulphurization technologies, as well as combinations of these two techniques wet flue gas desulphurization technologies are currently in our application example, are desulphurization and dust removal is the integration of technology, has launched fast, efficient, practical features.
Novel and effective water film spin disordered desulphurization and dust removal technology, the boiler flue gas treatment, especially for water film has been equipped with granite dust to the boiler flue gas treatment, the most appropriate integration of China's national conditions of environmental desulphurization and dust removal practical technology, it has changed a small amount, launched soon, do not be covering; investment, low operation cost, high efficiency desulphurization and dust removal; equipment without fouling, not blocking, without water, no secondary pollution, huge advantage.
Under the State Council on the two control acid rain and sulfur dioxide pollution control areas "15" Plan approval: to ensure that the two control areas in 2005 compared to 2000 to reduce sulfur dioxide emissions by 20%.
According to statistics, China's sulfur dioxide emissions in 2000 was 19,950,000 tons, while the two control areas was 13.164 million tons of sulfur dioxide emissions, accounting for about 66% of the total, according to "15" plan calls for the year 2005 The two control sulfur dioxide emissions in the region not only can not increase, but also 20% less than in 2000, a reduction of 2.633 million tons, can be seen, our two sulfur dioxide pollution control areas very difficult task.
