With the rapid development of social economy and the further acceleration of industrialization, a large number of gaseous pollutants (mainly organic or inorganic substances containing paint, sulfur, nitrogen and oxygen) are produced in the industrial process, forming industrial waste gas. Untreated industrial waste gas discharged into the atmosphere will seriously pollute the environment and affect the quality of life of nearby residents. For example, it can make people feel unwell, such as headache, dizziness, nausea, vomiting, loss of appetite and inattention. In addition, it also affects human respiratory system, circulatory system, digestive system and reproductive system.
Countries all over the world attach great importance to flue gas desulfurization, and have developed dozens of effective desulfurization technologies. Among them, lime / limestone gypsum wet desulfurization technology is widely used, which has many advantages, such as wide application of coal, cheap raw materials, high desulfurization rate (up to 90%) and so on. It occupies a large market share, but the investment and operation costs are large, and the amount of operation and maintenance is large Big.
The advantages of desulfurization catalyst can improve desulfurization efficiency without equipment expansion and transformation; save energy and reduce consumption (save auxiliary power); reduce limestone consumption; improve the flexibility of coal adjustment and desulfurization operation and standby; increase the dispersion of limestone to reduce equipment scaling; improve oxidation efficiency, reduce sulfite content, and improve the dehydration efficiency of vacuum belt conveyor.
There are many uses of desulfurization catalyst in industry, especially for today's industry, it is basically inseparable, and the use of desulfurization catalyst in the treatment of boiler flue gas can bring a lot of convenience to our industrial manufacturing. SO2 pollution has exceeded the dust pollution and become a major pollutant in the atmospheric environment. With the deepening of industrialization in the world, flue gas desulfurization (FGD) is different from other desulfurization methods. It is the only large-scale commercial desulfurization method in the world. It is a more effective and main technical means to control acid rain and SO2 pollution.
The above is an introduction to the importance of industrial tail gas desulfurization. I believe you all know it. For more wonderful information, please click our website: biological desulfurization http://www.zzzop.cn
