Selection of desulfurization pump in ammonia desulfurization project

With the continuous economic development, more and more sulfur dioxide is emitted from fossil fuels, causing serious environmental problems and causing huge economic losses. Control of sulfur dioxide emissions has become the primary content of the current environmental issues, flue gas desulfurization technology has been greatly developed.

In flue gas desulfurization process, ammonia desulfurization is an efficient, low-energy wet desulfurization. Desulfurization system desulfurization raw materials are ammonia and water, desulfurization products are solid ammonium sulfate, the process does not produce new emissions, waste water and waste. Both recovered sulfur resources, but also does not produce secondary pollution. In the system, the selection of desulfurization pump is directly related to the correct operation of the entire desulfurization system is normal.

Ammonia desulfurization desulfurization pump main circulating medium ammonium sulfate, ammonium sulfite, dust particles, a large number of chloride ions, corrosive, mainly chemical corrosion, electrochemical corrosion, crystalline corrosion. Dust effect is related to a certain amount of wear and tear. For metal materials, the general choice of ultra-low carbon chemical corrosion of stainless steel, such as 316L, duplex steel 2507, but there will be pitting, weld corrosion. Ya Mei Pump Group YMTL series desulfurization pump, lined with the overall ultra-high molecular weight polyethylene, corrosion-resistant, anti-crystallization. Mechanical seal using pressureless sintered silicon carbide, long service life. At present, the type of desulfurization pump maximum flow to 1200 cubic meters / hour, has been used in a number of ammonia desulfurization project, the use of good results.
