When selecting FRP desulfurization tower, high desulfurization efficiency and excess limestone rate must be considered comprehensively. Otherwise, the service life of FRP desulfurization tower will be seriously affected.
There are more than 200 desulfurization processes, among which the wet flue gas desulfurization process has been applied in developed countries for 20 years. Compared with other processes, the wet flue gas desulfurization process has the following advantages:
1. Experience in long-term application of thermal power plants;
2. High efficient desulfurization and absorption;
3. Good usability.
Membrane deamination
In the desulfurization unit, the flue gas circulating fluidized bed desulfurization technology (cfb-fgd) is a widely used semi-dry desulfurization technology in the internal cycle of the desulfurization unit, and the gas-solid two-phase flow in the multi-stage flue gas desulfurization tower. Recovery and utilization of high concentration materials is one of the characteristics of high desulfurization efficiency and utilization ratio of desulfurizer. The desulfurization efficiency can be increased by 10%~15% by the circulation of solid particles. When feed Ca/S is low, the effect on desulfurization efficiency is particularly significant.
Membrane deamination
This is one, the other is the binary multi-step water curtain FRP desulfurization tower, which is improved twice in traditional wet condition. The FRP desulfurization tower has become a new type of FRP desulfurization tower. The binary slurry has different pH value control. Low pH value promotes dissolved calcium carbonate and high pH value improves the absorption effect of sulfur dioxide. At the same time, multi-stage water curtain strengthens the gas-liquid flow state, increases the gas-liquid contact area and mass transfer capacity, and promotes the absorption effect of sulfur Absorption of SO2. Double-cycle multi-stage water curtain FRP desulfurization tower has good application prospects.
