Semi-dry flue gas desulfurization process is a commonly used desulfurization method, and its advantages are mainly manifested in the following aspects:
1.Efficient desulfurization: The semi-dry flue gas desulfurization process uses semi-dry desulfurization agent, which has a high desulfurization efficiency. Under suitable operating conditions, the desulfurization efficiency can be guaranteed to reach more than 90%, so as to effectively control the emission of sulfur dioxide.
2.Strong adaptability: The semi-dry flue gas desulfurization process is suitable for flue gas treatment equipment such as boilers and kilns of various sizes. When dealing with equipment with a small flue gas volume, the desulfurization effect can be ensured by adjusting the process parametersWhen dealing with equipment with a large flue gas volume, it is still able to maintain a high desulfurization efficiency.
3.Easy to operate: The operation of the semi-dry flue gas desulfurization process is relatively simple and easy to master. In the process, only a few key parameters need to be monitored and adjusted, such as flue gas temperature, flue gas flow, desulfurizer concentration, etc. In addition, the process requires relatively little equipment maintenance and overhaul.
4.Water saving: Compared to the wet desulfurization process, the semi-dry flue gas desulfurization process does not require the use of large amounts of water for desulfurization. In water-scarce areas or enterprises with scarce water resources, the semi-dry flue gas desulfurization process can effectively save water resources and reduce production costs.
5.No secondary pollution: The products of the semi-dry flue gas desulfurization process are dry and will not produce secondary pollutants such as sulfur-containing waste liquid. At the same time, the process will not cause corrosion and fouling problems to the equipment, prolonging the service life of the equipment.
6.Renewable: Semi-dry flue gas desulfurizers generally use alkaline oxides as absorbents, and these absorbents can be reused after use. By restoring the absorbent to its original state through a regeneration unit, it is possible to reduce costs and environmental impact.
7.Suitable for different coal quality: The semi-dry flue gas desulfurization process has strong adaptability to coal quality and can process various types of coal. Whether it is high-sulfur coal or low-sulfur coal, it can achieve a better desulfurization effect.
8.Lower operating costs: The semi-dry flue gas desulfurization process has lower operating costs compared to the wet desulfurization process. Since there is no need to use large amounts of water and energy-intensive equipment, energy consumption and maintenance costs can be reduced. In addition, since the semi-dry flue gas desulfurizer can be reused, the operating costs are further reduced.
9.Environmental protection: As a clean production technology, the semi-dry flue gas desulfurization process has good environmental performance. By removing harmful substances such as sulfur dioxide, pollution and damage to the environment can be reduced. At the same time, the dry products produced by the process can also be comprehensively utilized or safely disposed of, without generating pollutants such as waste liquid.
10.Wide range of applications: The semi-dry flue gas desulfurization process is not only suitable for production equipment such as industrial boilers and kilns, but also for large thermal power plants and waste incinerators. In all of these areas, the process has demonstrated excellent desulfurization performance and stability.
In summary, the semi-dry flue gas desulfurization process has the advantages of efficient desulfurization, strong adaptability, easy operation, water conservation, no secondary pollution, renewable utilization, suitable for different coal quality, low operating cost, environmental protection and a wide range of applications. These advantages make the semi-dry flue gas desulfurization process an excellent desulfurization technology, which has made a positive contribution to environmental protection and industrial production.
