脱硝应用

脱硝应用

脱硝应用:

伴随经济的快速发展,工业化速度加快,工业生产过程中产生大量的废气、废水、和固体废弃物。其中,含有NOx排放量和 大气NOx浓度的快速增加,大气的氧化性增加,产生如酸雨、光化学烟雾、破坏臭氧层等的城市和区域环境问题,对人类身体健康和生态环境造成巨大的影响。为了改善日益严重的NOx污染,世界卫生组织做不懈的努力,采用燃烧中脱氮和燃烧后烟气净化技术,减少NOx排放量。

燃煤电厂

在我国火力发电是主要的发电形式,且在今后相当长的时间内这一格局都不会发生大的改变。 在我国,氮氧化物等有害物质主要是由燃煤过程产生的。

水泥厂

水泥的回转窑采用低NOx燃烧技术,主要是分级燃烧技术和废气脱硝技术。那么较经济的废气脱硝技术选择性非催化还原法(SNCR)是采用废气内喷氨水(或尿素)。

垃圾焚烧炉

城市生活垃圾采用焚烧方法处理,焚烧烟气中含有大量酸性气体(如HCl、SO2、HF、HBr、NOx)、有机类污 染物(如PCDDs、PCDFs)、颗粒物及重金属等。因为无害化较彻底、减容量大、处理时间短、可以回收热能、占地面积较小等优点。为了降低NOx的排放,必须对燃烧后的烟气进行脱硝处理。

其它

烟气脱硝处理除了应用在燃煤电厂、水泥厂和垃圾焚烧炉外,还应用于工业锅炉、燃气/燃油锅炉、柴油机、工业窑炉、石化、汽车尾气处理、焦化厂、钢铁冶金、玻璃、造纸及其它行业。

Denitration application:
Along with the rapid development of economy, the speed of industrialization, the industrial production process to produce large amounts of waste gas, waste water, and solid waste.Which containing NOx emissions and rapidly increasing the concentration of NOx in the atmosphere, increased atmospheric oxidation, such as acid rain, photochemical smog, destruction of the ozone layer and other urban and regional environmental problems, and to human health and ecological environment caused a huge impact.In order to improve the NOx pollution increasingly serious, the unremitting efforts of the world health organization (who), the denitrification and burned in the combustion flue gas purification technology, reduce NOx emissions.
Coal-fired power plants
Thermal power is the main form of electricity generation in our country, and this pattern in quite a long time in the future will not happen big changes.In our country, the harmful material such as nitrogen oxides is mainly produced by coal burning process.
Cement plant
Cement rotary kiln with low NOx combustion technology, the main is burning technology and flue gas denitration technology classification.So the economy and flue gas denitration technology of selective catalytic reduction method (SNCR) is to use waste gas gush ammonia or urea.
Garbage incinerator
Municipal solid waste incineration method, burning smoke contains a large number of acid gases (such as HCl, SO2, HF, gets, NOx), organic pollution content (e.g., PCDDs, PCDFs), particulate matter and heavy metals, etc.Because more thoroughly, JianRongLiang innocuity, short processing time and can be recycled heat, covers an area of small advantages.In order to reduce the emission of NOx, must after the burning of flue gas denitration processing.
other
Flue gas denitration process in addition to the application in coal-fired power plants, cement plants, and garbage incinerator, also used in industrial boiler, gas/oil burning boiler, diesel engine, industrial furnaces, petrochemical, automobile exhaust treatment, coking plant, steel, metallurgy, glass, paper and other industries.
