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, with symptoms such as headache, dizziness, nausea, vomiting, loss of appetite and lack of concentration. In addition, it also affects people's respiratory system, circulatory system, digestive system and reproductive system.
Countries all over the world attach great importance to biological desulfurization and have developed dozens of effective desulfurization technologies. Among them, the widely used flue gas desulfurization technology is lime / limestone gypsum wet method, which has many advantages, such as wide application of coal, cheap and easy availability of raw materials, high desulfurization rate (up to more than 90%), and occupies the largest market share, but the investment and operation cost are large, Large amount of operation and maintenance.
The advantages of desulfurization catalyst can improve desulfurization efficiency without equipment capacity expansion and transformation; Energy saving and consumption reduction (saving auxiliary power); Reduce limestone consumption; Improve the flexibility of coal adjustment and desulfurization operation and standby; Increase the dispersion of limestone and reduce the scaling of equipment; Improve oxidation efficiency, reduce sulfite content and improve dehydration efficiency of vacuum belt conveyor.
Desulfurization catalyst has many uses in industry, especially for the current industry, which is basically inseparable from it. 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 soot pollution and become the largest pollutant in the atmospheric environment.
With the deepening of industrialization in the world, biological desulfurization is different from other desulfurization methods. It is the only large-scale commercial desulfurization method in the world. It is the most effective and main technical means to control acid rain and SO2 pollution.
