http://www.hakatayanoodle.com煤炭在我國的能源結構中所占比例很大,在我國的一次能源消費總Z中,煤炭占75%,而國外平均為28%.在我國的電力構成中,火電占了80%,而火電中有95%以上燒煤。2000年,全國發電總耗煤量為6億噸,占煤炭總產量的60%,排放502800多萬噸,占全國排放總量的40%以上。而我國火電行業的煙氣脫硫才剛剛起步,具有脫硫設施的機組容量不到全部火電機組的5%.

酸雨是當今世界三大環境問題之一。由于燃料燃燒產生的煙氣中SO2是形成酸雨的主要原因,世界各國都把煙氣脫硫作為控制SO2污染、防治酸雨危害的主要技術手段。隨著工業現代化程度的提高,我國環境問題變得越來越嚴重。SO2的排放量不斷增大,中國二氧化硫排放總量已居世界第一,超出大氣環境容量的80%以上,西南、華南等地出現大面積的酸雨,酸雨區面積約占國土面積的1/3,已成為繼北美、歐洲之后的世界第三大酸雨區……為控制以SO2排放為主造成的酸雨污染的惡化趨勢,我國新的大氣污染防治法已頒布,二氧化硫排放收費制全面推行,研究、開發、推廣應用各種脫硫技術已勢在必行。

煙氣脫硫技術的發展日新月異,鎂法脫硫技術以其投資小、運行費用低、環保效益好、脫硫效率高,可回收副產品和產生一定的經濟效益等特點,同時又避免了大型濕法的諸多缺點,因此氧化鎂脫硫技術將會逐步得到更廣泛的應用,正越來越受到人們的關注。

氧化鎂脫硫技術,在世界各地都有很多的應用業績,其中在13本已經應用了100多個項目,臺灣的電站95%是用氧化鎂法,美國、德國等地都已經應用,目前我國已開始推廣,并在一部分地區得到成功的應用。例如我國的耐火行業生產的耐火制品(輕燒鎂粉,輕燒鎂球,苦土粉等)就是應用到了氧化鎂脫硫技術。 

 

 

http://www.hakatayanoodle.com Coal accounts for a large proportion of China's energy structure. Among China's total primary energy consumption, coal accounts for 75%, while foreign countries average 28%. In China's electricity composition Thermal power accounts for 80%, and more than 95% of thermal power burns coal. In 2000, the country's total coal consumption for power generation was 600 million tons, accounting for 60% of total coal production, and emissions of more than 50,280 million tons, accounting for more than 40% of the country's total emissions. The flue gas desulfurization in China's thermal power industry has just started, and the capacity of units with desulfurization facilities is less than 5% of all thermal power units.

Acid rain is one of the three major environmental problems in the world today. Because SO2 in the flue gas generated by fuel combustion is the main reason for the formation of acid rain, countries around the world have taken flue gas desulfurization as the main technical means to control SO2 pollution and prevent the harm of acid rain. With the improvement of industrial modernization, China's environmental problems have become more and more serious. SO2 emissions continue to increase, and China ’s total sulfur dioxide emissions have ranked first in the world, exceeding 80% of the atmospheric environmental capacity. Southwest, South China, and other places have experienced a large area of acid rain. The area of acid rain accounts for about 1/3 of the land area. Has become the third largest acid rain area in the world after North America and Europe ... In order to control the deterioration trend of acid rain pollution mainly caused by SO2 emissions, China ’s new air pollution prevention law has been promulgated, and the sulfur dioxide emission charging system has been fully implemented. It is imperative to develop, promote and apply various desulfurization technologies.

The development of flue gas desulfurization technology is changing rapidly. Magnesium desulfurization technology has the characteristics of small investment, low operating costs, good environmental protection benefits, high desulfurization efficiency, recyclable by-products and certain economic benefits, while avoiding many of the large wet process Disadvantages, therefore, magnesium oxide desulfurization technology will gradually be more widely used, and is receiving more and more attention.

Magnesium oxide desulfurization technology has a lot of application achievements around the world. Among them, more than 100 projects have been applied in 13 books. 95% of Taiwan ’s power stations use the magnesium oxide method. The United States, Germany and other places have been used. Began promotion and successfully applied in some areas. For example, the refractory products (light-burned magnesium powder, light-burned magnesium balls, bitter clay powder, etc.) produced by the refractory industry in China are applied to the magnesium oxide desulfurization technology.
