烟气脱硫脱硝为什么需要加热处理?

首页- 新闻资讯 > 行业资讯 > 2022-06-09

随着我国工业的不断进步,锅炉燃烧柴油产生的废气越来越多,主要含有SO2.NOX.烟尘、林格曼黑度等污染物。如果这些污染物随意排放到大气中,将对当地生态环境产生相当恶劣的影响。为了保护我国生态环境的完整性,保护环境和经济的可持续发展,锅炉废气应脱硫。生物脱硫也应运而生。

With the continuous progress of China's industry, more and more waste gas is produced by burning diesel oil in boilers, mainly containing so2 NOX. Pollutants such as soot and ringerman blackness. If these pollutants are discharged into the atmosphere at will, they will have a very bad impact on the local ecological environment. In order to protect the integrity of the ecological environment and the sustainable development of the environment and economy, the boiler exhaust gas should be desulfurized. Biological desulfurization also came into being.
目前,烟气脱硫脱硝处理技术多种多样,包括PAFP.ACFP.软锰矿法.电子束氨法.脉冲电晕法.石膏湿法.催化氧化法.微生物降解法等技术,其中湿法烟气脱硫脱硝快、常见。
At present, there are various flue gas desulfurization and denitration treatment technologies, including pafp ACFP. Pyrolusite method Electron beam ammonia method Pulse corona method Gypsum wet process Catalytic oxidation method Microbial degradation and other technologies, among which wet flue gas desulfurization and denitration are fast and common.
常见的烟气脱硫方法包括干式脱硫和湿式脱硫。干式脱硫是利用催化剂和吸收剂去除烟气中的二氧化硫。不同的催化剂和吸附剂也有不同的作用。更广泛使用的吸收剂类型是氧化物和活性炭。虽然干式脱硫是有效的,但由于不能回收,吸收成本高。湿式脱硫和干式脱硫均采用液体吸收剂。石灰石和海水脱硫是湿式脱硫的主要操作方法。因此,我国绝大多数企业都使用湿式脱硫进行相关操作。
Common flue gas desulfurization methods include dry desulfurization and wet desulfurization. Dry desulfurization uses catalyst and absorbent to remove sulfur dioxide from flue gas. Different catalysts and adsorbents also have different effects. The more widely used types of absorbents are oxides and activated carbon. Although dry desulfurization is effective, the absorption cost is high because it cannot be recovered. Liquid absorbent is used for wet desulfurization and dry desulfurization. Limestone and seawater desulfurization are the main operation methods of wet desulfurization. Therefore, the vast majority of enterprises in China use wet desulfurization for relevant operations.
湿法烟气脱硫技术有很多优点:湿法烟气脱硫技术是气液反应,反应速度快,脱硫效率高,一般高于90%,技术成熟,海洋之神。湿法脱硫技术相对成熟,生产运行可靠,在众多脱硫技术中始终占据主要地位。
The wet flue gas desulfurization technology has many advantages: the wet flue gas desulfurization technology is a gas-liquid reaction, with fast reaction speed and high desulfurization efficiency, generally higher than 90%. The technology is mature and widely used. Wet desulfurization technology is relatively mature and reliable in production and operation. It has always occupied a major position in many desulfurization technologies.
