Industrial flue gas emissions, especially sulfur dioxide and nitrogen oxides that exceed standards, are an important threat to the ecological environment and life and health.
The development concept of "green water and green mountains are golden mountains and silver mountains" and the in-depth development of pollution prevention and control battles are an important measure to promote high-quality economic, ecological and social development with the overall focus on reducing pollution and carbon. Propeller for the important goal of carbon neutrality.
What is carbon peak and carbon neutral?
Carbon peak refers to a region or industry’s annual carbon dioxide emissions reaching the highest value in history, and then experiencing a plateau period into a continuous decline. It is the historical turning point of carbon dioxide emissions from increasing to decreasing, marking the decoupling of carbon emissions from economic development. , The peak target includes peak year and peak value.
Carbon neutrality refers to the direct and indirect emission of carbon dioxide from anthropogenic activities in a certain area within a certain period of time (generally one year), which offsets the carbon dioxide absorbed by afforestation, etc., to achieve "net zero emission" of carbon dioxide.
The government work report for 2021 clearly proposes to do a good job in carbon peaking and carbon neutrality, formulate an action plan for peaking carbon emissions by 2030, and optimize the industrial structure and energy structure.
As a key area of ??Beijing-Tianjin-Hebei air pollution prevention and control, Beijing emphasized in its energy plan for 2021 that coal consumption will not exceed 1.5 million tons, and the proportion of high-quality energy consumption will reach 98% or more; Zhejiang’s technological innovation and development "14th Five-Year Plan" is particularly Emphasize the strengthening of carbon peak carbon neutral technology support, accelerate the application of green and low-carbon advanced and applicable technologies in key carbon emission industries and low-carbon pilot areas, and facilitate the green and low-carbon transformation of production and lifestyle.
Only by insisting on source control, system control, and overall control of flue gas control can we better promote the continuous improvement of the quality of the ecological environment, and realize the value of ecological products and the effect of ecological premium. Drive flue gas treatment with technological innovation, support blue sky, clear water, pure land, and waste removal activities, and strengthen the prevention and control of air, water, soil, solid waste and other pollution and protect the ecological environment through a series of ammonia desulfurization, denitration, whitening and dust removal technologies. The original intention and persistence of environmental protection "improving human living environment and improving people's quality of life".
In the "14th Five-Year Plan" of ecological and environmental protection, Zhejiang places special emphasis on the in-depth treatment of industrial furnaces and kilns during the 14th Five-Year Plan. During the "13th Five-Year Plan" period, Zhejiang has eliminated and transformed 25,000 small coal-fired boilers, and eliminated 9,503 industrial enterprises with backward and excess capacity.
However, the local structural and industrial pollution is still more prominent. The main manifestations are: coal-based energy structure has not been fundamentally changed, natural gas and other clean energy supply capacity and utilization scale are still low, the process of industrial low-carbon transformation needs to be accelerated, and carbon dioxide emissions Reaching the peak in advance faces greater pressure. The level of industrial ecologicalization is not high. The traditional manufacturing industry represented by textiles, leather, paper, rubber and plastics, metal products, etc., is relatively weak in terms of its theoretical foundation and technological level, and its input-output efficiency is generally low.
Optimizing and adjusting the industrial structure is imminent. Traditional industries such as petrochemicals, chemicals, steel, building materials, non-ferrous metals, cement, plate glass, casting, textiles, chemical fibers, pharmaceuticals and chemicals, ceramics, bricks and tiles, refractory materials and other traditional industries are carrying out green design and applying green production technology and equipment. It is imperative to carry out green technological transformation, reduce the elimination of backward and excess capacity, and establish a green supply chain management system.
In the comprehensive renovation of boilers, coal-fired boilers below 35 steam tons/hour will be completely eliminated. Ammonia desulfurization technology can be adopted for low-nitrogen retrofits of gas-fired boilers and ultra-low emission retrofits of biomass boilers in built-up areas. "To do environmental protection with the concept of chemical industry, to do industry with the concept of environmental protection, and to solve environmental problems with the concept of ecology" as the concept, cultivate new business models and new models of green transformation and development, and promote a good ecological environment to become a strong support for the sustainable and healthy development of the economy and society.
