Description

Technical Field

[0001] The invention relates to the technical field of thermal power plants, in particular to a desulfurization device for a thermal power plant. Background Art

[0002] Boilers, as indispensable energy conversion devices in industrial production and civil fields, play an important role in efficiently converting chemical energy and electrical energy in fuel into thermal energy. The output forms are diverse, including steam, high-temperature water and even organic heat carriers that contain rich thermal energy. They are widely used in various factories and provide a continuous source of power support for production activities. However, while the boiler is operating efficiently, the flue gas generated during its combustion process has become an environmental issue that cannot be ignored.

[0003] Boiler flue gas, a seemingly invisible product, actually contains complex components. Among them, solid particles such as fly ash and carbon black, as well as gaseous pollutants such as sulfur and nitrogen oxides, together constitute a potential threat to the atmospheric environment. If directly discharged without treatment, these pollutants will not only have a serious impact on air quality, but may also cause a series of environmental problems such as acid rain and photochemical smog, posing a dual challenge to natural ecology and human health.

[0004] In view of this, it is particularly important to effectively purify boiler flue gas. Flue gas desulfurization and denitrification equipment, as a key technical means to deal with boiler flue gas pollution, plays a role that cannot be underestimated. However, in practical applications, traditional flue gas desulfurization and denitrification equipment still has many shortcomings. One of the most significant problems is its limited ability to filter and purify dust and impurity particles in the flue gas.

[0005] In the traditional treatment process, flue gas is often directly introduced into the desulfurization and denitrification equipment for treatment, but there is a lack of effective pretreatment for dust and impurities. This practice not only causes a large amount of dust and impurities to enter the equipment with the flue gas, affecting the smooth progress of the desulfurization and denitrification reactions, but may also cause wear and blockage of the equipment, reduce treatment efficiency, and increase maintenance costs. More seriously, the presence of dust and impurities may also interfere with the normal function of the desulfurization and denitrification agents, affecting the final treatment effect, making it impossible to effectively remove harmful substances in the flue gas.

[0006] In addition, the traditional flue gas desulfurization and denitrification equipment also has obvious deficiencies in the use of desulfurization and denitrification solutions during the treatment process. On the one hand, due to the lack of effective filtration and recycling mechanism for desulfurization and denitrification solutions, a large amount of solutions are discarded after a single use, resulting in a huge waste of resources. On the other hand, the huge consumption of desulfurization and denitrification solutions not only increases the operating costs of enterprises, but may also cause additional burdens on water resources.

[0007] In view of the above problems, it is imperative to develop more efficient and environmentally friendly boiler flue gas desulfurization and denitrification technologies. The future development direction should focus on improving the dust and impurity filtering capacity of the equipment, and by adding efficient dust removal devices, ensure that the flue gas entering the desulfurization and denitrification equipment is purer, laying a good foundation for the subsequent treatment process. At the same time, research on the recycling of desulfurization and denitrification solutions should be strengthened, and by developing advanced filtering technology and recovery systems, the solution can be recycled multiple times to reduce resource consumption and environmental pollution.

[0008] In summary, the optimization and upgrading of boiler flue gas desulfurization and denitrification equipment has become a top priority. Through technological innovation and process improvement, not only can the flue gas treatment efficiency and quality be improved, but also the operating costs of enterprises can be effectively reduced, achieving a win-win situation of economic and environmental benefits. In future development, we should continue to pay attention to the latest progress of boiler flue gas treatment technology and contribute to the promotion of green and sustainable industrial production. In view of this, in-depth research on the above issues has led to the creation of this case. Summary of the invention
