Important preconditions on the boiler flue gas dust removal and desulfurization process design engineering boiler flue gas dust removal and desulfurization project is constantly improving our air quality and reducing acid rain PH value. This article will focus on an overview of the relevant boiler flue gas dust removal and desulfurization project elaboration, analysis related to boiler flue gas dust removal and desulfurization process design engineering, to provide reference for China to improve environmental standards. Overview of related dust and sulfur dioxide in the flue gas dust removal and desulfurization project 1 boiler is the main material damage caused by acid rain and the atmosphere, and it is a form of sulfur dioxide is not a harmful gas has a color and pungent, severe cases can damage the atmosphere structure, resulting in environmental change. Not only that, people living with the process of the production process will produce some harmful dust and sulfur dioxide gas, once the proportion of air in these components is too high it will endanger people's health. But also pose a serious hazard to respect people's productive activities, industrial production, construction and so on. Boiler is an energy conversion device, the input energy to the boiler fuel chemical energy, electrical energy, thermal energy and other forms of high temperature flue gas, and after converting the boiler, the steam output have a certain outward heat, hot water or organic heat . Boiler is one of the main tools of our country's major industrial production, which will use special means to go after some of the energy input material must be converted into energy, in order to adapt to the development industry. But in the course of the boiler will emit harmful substances, although it will increase the efficiency of economic and industrial development in a way, but also bring a certain degree of damage to the environment, severe cases can endanger human safety. Current coal resources and consumption of oil resources gradually increased, resulting in dust emissions and sulfuric acid type gas also increases. So our national government to protect the environment but also introduced the corresponding countermeasures, continuous improvement boiler flue gas dust removal and desulfurization process design engineering methods to improve its environmental efficiency. Flue Gas Desulfurization relevant principles of the boiler 2 into the operating principle of this embodiment 2.1 magnesia mainly refers to the use of a slurry containing MgO as a desulfurizing agent in the wash, MgO is converted to magnesium sulfite (MgSO3) and magnesium sulfate (MgSO4), the sulfur is then removed from the solution. This approach boiler dust desulfurization more mature and has been widely used in Japan and Taiwan and other regions in mainland China also has many factories, dust removal and desulphurization work in this way. Moreover, this method of dust removal and desulfurization efficiency above 90%, help protect the environment, improve the current air quality. Also in the case where the like, the amount of magnesium oxide with calcium carbonate Desulfurization only two fifths, this method shows a high utilization of raw materials, and the effect is more obvious. Currently stored amount of magnesium oxide in our country up to 80 billion tons, ranking first in the world in mining technology is also more skilled, and therefore has a considerable edge for our country. 2.2 works swirl plate absorber tower for flue gas desulphurization dust from the boiler is first enters the venturi tube, for spraying a primary dust desulfurization treatment, and then a flow rate of 15 ~ 22m / s is tangentially into the swirl plate column cylinder, firstly by the action of centrifugal force, thrown large particles in the flue gas to the tower wall, and a top-down flow of the absorbing liquid trap. This method enables the boiler flue dust separated from the gas, and to achieve the object of dust removal and desulfurization. 3 boiler flue gas dedusting flue gas desulfurization process design inside the boiler through the heat exchanger after the dust removal device into efficient desulfurization device or directly into efficient desulfurization and dust removal device, and then use the exhaust chimney draft fan. In the dust removing device which will produce gray water tank into the lime, a process using sodium lye bath kinds sodium lye, then became lime mud. If there is still the use of multi-level gray water and sludge pump liquid precipitation treatment, after diluting the high water level of the pool can be completed. Therefore, in the boiler flue gas dust removal and desulfurization process engineering design process to rational design exhaust system, flue gas purification systems, precipitation systems, inspection systems, power systems, and infrastructure-related aspects. And actively improve the quality and level design to ensure that the results of the boiler flue gas dust removal and desulfurization national environmental standards in line with the relevant departments to develop. In the process design process should also consider the cost of construction of the whole project, detailed estimates of its economic benefits and social benefits. In the course of implementation should strengthen supervision and management, to improve the quality of the environment and efforts. 4 Conclusion With the improvement of scientific and technological level of China's industrial development speed greatly accelerated. But in the process of industrial development often will use some of the energy resources, such as coal resources, oil resources and other aspects of chemical materials, use of these resources in the process will produce some waste is not conducive to environmental sustainability. Therefore, the relevant enterprises and departments should actively improve the quality of the boiler flue gas dust removal and desulfurization, improve the rationality of engineering process design, lay the foundation for improving the economic and social benefits. This requires the joint efforts of government departments and enterprises, the only way our country's socialist market economy to be able to achieve sustainable development goals, to be able to improve the economic benefits of the greatest degree.
Battle for winning Blue Sky, effectively improve the region's ambient air quality; Ningxia Hui Autonomous Region developed and published a "region-owned coal-fired thermal power units reconstruction plan for the ultra-low emission" (hereinafter referred to as the "Program"). "Plan" put forward plans before the end of 2020, nine companies owned coal-fired power plant 25 thermal power units for ultra low emissions transformation.
By the end of 2020, all the region's coal-fired thermal power units with self-transformation conditions by upgrading desulfurization, denitrification and dust removal facilities, the concentration of pollutants in atmospheric emissions all meet ultra-low emission requirements; long-discontinued businesses in the pre-production must be restored owned ultra-low emission coal-fired units to complete the transformation; gradually shutting down key areas do not have the conditions for the transformation of high-polluting coal-fired captive power plants; emission concentration of air pollutants new coal-fired gas turbine generator set to achieve set emission limits; the country City and Ningdong Management Committee in conjunction with the region's environmental quality improvement requirements, and actively promote the transformation of ultra-low emissions to arrange more than 65 tons of steam per hour of coal-fired boilers.
After the completion of the transformation project, owned coal-fired power plants should entrust a third party consultant for technical performance, environmental effects, equipment stability, comprehensive assessment, evaluation findings and issue.
In order to encourage enterprises to increase efforts to transform ultra-low emissions of pollutant emission concentrations below the pollutant discharge limits set by the state or place more than 50 percent, halved implement environmental tax policy. At the same time, we encourage financial institutions to give preferential credit support, to support eligible owned coal-fired thermal power enterprises to issue corporate bonds direct financing, to raise funds for ultra-low emissions and energy saving. According to the regional administration of appropriate incentive funding arrangements, to ultra-low emission reduction projects included renovation crew around them, give appropriate incentives based on emission reductions, combined with local conditions to increase financial support.
"Plan" requires all localities and departments should strengthen daily supervision and inspection of law enforcement to prevent corporate fraud, is not scheduled to complete the transformation of the self-ultra-low emission thermal power phase-out, discharge permit authorities to promptly subtract the emissions permit, for non-compliance business severely dealt with according to the law, to the public.
WNS What are the advantages of gas condensing boiler with the country's commitment to increasing air pollution control throughout the country have introduced corresponding policy, enacted almost everywhere timing and amount of boiler. In order to save operating costs, most enterprises in the transformation process of the boiler will choose a coal-fired boiler is a condensing gas boiler. So, we need to WNS What are the advantages of a gas condensing boiler detailed understanding. WNS gas condensing boilers What are the advantages of air pollution coefficient small traditional coal-fired boiler during operation will generate a lot of smoke pollution, which is extremely detrimental to the environment, but high-quality gas condensing boiler has to gas as a power source, replacing the traditional coal-fired way. Therefore, there is no coal pollution during operation, which is not only important for environmental protection, but also can reduce harmful gas emission purification device configuration, thus reducing operating costs. Higher safety coefficient due to condensation gas boiler advanced structural design and build these boiler systems have a variety of protective functions of protection, the system comprising high and low voltage protection against dry protection, overheating protection and to prevent leakage protection boiler, by function, the process of condensing gas boiler operation can effectively reduce the potential security risks because of negligence. Small high high-efficiency heat loss condensing gas boiler generated steam can be recovered, not only better water recycling, waste heat can be effectively collected. Meanwhile, the condensing gas boiler advanced temperature control, the internal heat loss of the entire boiler system small, more efficient energy utilization. Therefore, it is possible for enterprises to save a lot of electricity, water and fuel.
Burning coal in primary energy in the heating field will maintain the central position in the next several years.For a vast use of coal power, coal sulfur content distribution is very uneven, of which about 50% are in high sulfur coal (Sar>1%), harmful gas, coal-fired emissions of sulfur dioxide, nitrogen oxides, such as environmental pollution is becoming more and more serious. In order to improve this situation, at the same time, continue to use coal as a large heating fuel, the use of 58MW circulating fluidized bed coal for hot water boiler palembang can be said to be true.
