According to statistics, Zhejiang Province, coal consumption totaled 145.91 million tons, accounting for 56.8% of primary energy consumption in the province. Although after careful environmental management, but the main coal-dominated energy consumption remains high in the province's total emissions of air pollutants. In the "Zhejiang Air Pollution Control Action Plan (2013-2017)" issued in December 2013, the coal-fired pollution control remains a top priority.

According to "Zhejiang low-carbon development" Thirteen Five "plan", as of 2020, the province's proportion of non-fossil energy sources will be increased to about 20%, the proportion of the total coal consumption should be reduced to around 42%.

June 15 this year, Hangzhou Iron and Steel Group ironworks blast furnace in the chimney successful blasting, declared the "three noes" no way to urban development of Hangzhou steel companies, no coal-fired generating units, there is no standard yellow car.

To control pollution from coal-fired source, Zhejiang Province, facing elimination from the transformation of the boiler parties policy, funding, pricing, comprehensive resources supporting the work in 2015, 2016, 2017 were given every right out of steam coal-fired boilers tons 15,000 yuan, 12,000 yuan and 10,000 yuan subsidy funds.

To eliminate 10 tons of steam / hour of coal-fired boilers, in October 2014, Zhuji City, party and government "leaders" personally took, within three months, through the introduction of reward and subsidy standards, regular assessment and other measures, the city's 1964 stage production behind coal-fired boiler demolition 1508 units, 390 units to natural gas or electricity, and the rest use biomass fuel, gas tank or centralized heating, completed the task of transformation. It is estimated that, this year more than 500 tons of sulfur dioxide emissions.

After a clear goal, the province's coal-fired boiler (kiln) transformation to accelerate out of the furnace. According to statistics, in the first half of this year, Zhejiang Province eliminate small coal-fired boilers 6200 Taiwan, has completed 77.5% of the annual task of eliminating.

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.
