Description
Technical Field
The invention relates to the technical field of air pollution prevention and environmental protection, in particular to a carbon dioxide carbon-oxygen separation method and a special device thereof.
Background
The urban pollution problem in China is gradually highlighted along with the continuous acceleration of urbanization construction, so that the urban pollution has serious influence on the health of citizens, and the enhancement of atmospheric pollution control is imminent. Under the background that environmental pollution control policies and various atmospheric pollution control measures in China are continuously implemented, urban pollution is effectively relieved in recent years, prevention and emission reduction of conventional pollutants are powerfully controlled, however, due to unreasonable urban energy structure, effective management of vehicle exhaust emission and the like is not realized, and the trend that unconventional atmospheric pollutants are increased is caused. A report published by the world health organization and the environmental organization of the united nations: "air pollution has become an unavoidable reality in urban residents' life all over the world. "if human lives in air with serious pollution, it will die in a few minutes. Industrial civilization and urban development create huge wealth for human beings, and simultaneously, billions of tons of waste gas and waste are discharged into the atmosphere, and the atmosphere on which human beings live becomes an air garbage warehouse and a toxic gas warehouse. Therefore, when the harmful gases and pollutants reach a certain concentration, the harmful gases and pollutants bring great disasters to human beings and the environment.
As is known, the atmosphere is a mixture of nitrogen, oxygen, carbon dioxide, water vapor and solid impurity particles in a certain proportion, and in terms of dry air, the volume of nitrogen is 78.08%, the volume of oxygen is 20.94%, the volume of rare gas is 0.93%, the volume of carbon dioxide is 0.03%, and the volume of other gases and impurities is about 0.02% under a standard state. With the deep promotion of industrialization and urbanization in China, the energy resource consumption is continuously increased, the atmospheric pollution control pressure is continuously increased, and the main reason for the increase of haze weather in China is that atmospheric pollutants caused by fossil energy consumption are increased year by year, including thermoelectric emission, heavy chemical industry production, automobile exhaust, winter heating and the like. Before the social production and the life style are not fundamentally changed, the improvement of the environmental air quality in China cannot be achieved at once. At present, the atmospheric pollution treatment is initially effective in a short period under the pressure of pollution treatment of the iron wrists. But the current environmental quality has a large gap from the qualified environmental quality, the concentration of air pollutants in China is still high, the atmospheric pollution situation is still severe, and the air quality treatment is a long process, and the difficulty of improvement is increased in the later periodLarge, periods of meandering and even bouncing may also occur. Therefore, the environment becomes the bottleneck problem of the social development in China, and the bottleneck must be broken through to ensure that the environmental improvement becomes the engine of the national economic development rather than the burden of the development to ensure that the environmental improvement does not generate large rebound. In order to actually improve the air quality, the air pollution prevention and control law of the people's republic of China has been revised by the sixteenth conference of the institutional committee of the twelfth national representative of people of the people's republic of China in 2015 on 8 th and 29 th days, and the revised air pollution prevention and control law of the people's republic of China is published from 2016 to 1 th on 1 th. The law is issued and implemented, and the support and the guarantee of the law are provided for protecting and improving the environment, preventing and treating air pollution, guaranteeing public health, promoting ecological civilization construction and promoting sustainable development of economy and society. The method aims at preventing and treating atmospheric pollution and improving the quality of atmospheric environment, insists on source treatment, plans ahead of schedule, changes an economic development mode, optimizes an industrial structure and layout, adjusts an energy structure, comprehensively prevents and treats atmospheric pollution such as coal burning, industry, motor vehicles and ships, raise dust, agriculture and the like, pushes the combined prevention and treatment of regional atmospheric pollution, implements the integral implementation of cooperative control on atmospheric pollutants such as particulate matters, sulfur dioxide, nitrogen oxides, volatile organic matters, ammonia and the like and carbon dioxide causing greenhouse gases, and becomes a core problem of the comprehensive prevention and treatment of the atmospheric pollution. In the face of the controlled atmosphere environment, harmful gases such as smoke of a chimney, gas exhausted by a motor vehicle or a ship, dust, sulfur dioxide, carbon dioxide, nitrogen oxide and the like in the fields of agriculture and the like are continuously discharged, and the current situation that natural environment such as volcanic eruption, mountain fire, war disorder and the like exist in the atmosphere is caused. Therefore, air pollution control is a difficult project and a huge system project, and not only needs the common efforts of individuals, groups, countries and even countries all over the world, but also needs the collection of funds and technologies. Climate change is one of the biggest challenges facing the contemporary community as recognized by the twenty-year implementation of the 2030 sustainable development agenda action plan as stated in the report of the Hangzhou Congress of China on 2016, 9, 4 and 5 days in twenty-yearRealizing the capability of sustainable development. G20 members must take urgent action to cope with climate change, early implement Paris agreement, reiterate the commitment made by developed countries and international organizations on climate fund and statement of other countries, maintain the main channel function of the United nations climate change frame convention, continue to cope with climate change and its influence in close cooperation, promote the Paris agreement to take effect and implement early, encourage provision and mobilization of more resources to cope with climate change, encourage capital to flow to the low-temperature chamber gas emission and the development of climate toughness. At present, the atmospheric pollution situation in China is severe, and the Particles (PM) can be inhaled10) Fine Particulate Matter (PM)2.5) The regional atmospheric environment problem of characteristic pollutants is increasingly prominent, the health of people is damaged, and the social harmony and stability are influenced. With the deep promotion of industrialization and urbanization in China, the energy resource consumption is continuously increased, and the atmospheric pollution prevention pressure is continuously increased. The method has the advantages that the obvious improvement of the atmospheric environment quality is realized, the pollutant emission amount must be reduced from the current million-ton level to the million-ton level, the industrial structure and energy structure adjustment is further promoted, the key industry comprehensive improvement is promoted, the regional cooperation is deepened, the scientific and technological support is strengthened, the atmospheric pollution prevention and control are taken from the source, the atmospheric environment quality is checked, the optimal method for the atmospheric prevention and control is sought, the first comprehensive prevention and control in China is realized, the natural environment is improved, and the mankind is benefited. The main sources of atmospheric pollution are: the method comprises the following steps of firstly, producing pollution, which is a main source of air pollution, and comprises the following steps: combustion of fuel, mainly a large amount of harmful substances discharged in the combustion process of coal and petroleum, such as smoke dust and sulfur dioxide discharged by coal burning; the burnt petroleum can discharge sulfur dioxide, carbon monoxide and the like; secondly, the smoke dust and the waste gas discharged in the production process cause the most serious air pollution by a thermal power plant, an iron and steel plant, a petrochemical plant, a cement plant and the like; thirdly, the dust and fog generated by spraying pesticide in the agricultural production process are serious. And harmful gases such as smoke dust, sulfur dioxide and the like generated by coal consumption of the domestic cooking range and the heating boiler. The pollution caused by transportation and transportation, and the tail gas discharged by automobiles, trains, ships, airplanes and the like, wherein the harmful tail gas discharged by the automobiles is nearest to the respiratory zone, so that the harmful tail gas can be dischargedThe pollution is mainly nitrogen oxide, hydrocarbon, carbon monoxide, lead dust and the like, and the harm is as follows: atmospheric pollutants have a significant impact on human health, plants, equipment and materials, and on atmospheric visibility and climate. Therefore, it is an urgent and urgent technical problem for those skilled in the art to find a new, reliable, safe and environment-friendly carbon dioxide carbon-oxygen separation method and its special device, which is free from secondary pollution and can improve the natural environment and benefit the mankind.
