The advantages of FRP desulfurization tower compared to other materials:
Now with the development of FRP technology, desulfurization towers are gradually made of FRP. Compared with granite desulfurization towers, glass fiber reinforced plastic desulfurization towers have low cost, easy processing, no rust and no rot, and light weight, so they have become the development trend of future desulfurization towers. In addition, 316L stainless steel has three advantages: corrosion resistance, high temperature resistance, and wear resistance. It is also one of the important trends in the development of desulfurization towers. After years of improvement, it has developed into various types of desulfurization towers such as Venturi type, swirl plate type, swirl column type, floating ball type, sieve plate type, and pneumatic emulsification type. The equipment technology has become increasingly mature, each with its own advantages and Insufficient, enterprises can choose different types according to their own needs.
The main equipment commonly used in FRP desulfurization tower desulfurization systems are absorption towers, flues, chimneys, desulfurization pumps, booster fans and other major equipment. The technology has anti-corrosion and anti-wear effects in desulfurization pumps, absorption towers, flues, and chimneys Significantly.
With the continuous development of China's society and economy, coal power pollution has seriously endangered our living environment. Among them, thermal power plants are the largest households of air pollution in China. According to relevant data statistics, by 2020, China's thermal power plants will emit 2100 sulfur dioxide. More than 10,000 tons. Suppose that China's sulfur dioxide emissions should be cut in half and controlled at 12 million tons / year, of which sulfur dioxide emissions from electricity should be controlled at 5.5 million tons / year, which is undoubtedly a difficult task.
After the introduction of "the most stringent air pollution standards for thermal power plants in history", opinions such as "the standards are too strict, the coal-fired power plants have a huge amount of technical transformation work and tight schedules, and large capital investment but insufficient subsidies" have taken the mainstream. This is in stark contrast to the current initiative by power companies to move towards higher levels of pollutant emissions. For many reasons, the work of desulfurization and denitrification in thermal power plants in China is not done well. Since the desulfurization work was carried out earlier, the penetration rate has reached more than 90%, but the degree of equipment operation is worthy of concern.
