How steel industry achieve green development during period of "Thirteen Five"?
- Interview with China Iron and Steel Industry Association, the Ministry of Development and Environmental Protection Technology Officer Huang Dao
Concept of green development across the whole of society, in the upcoming "Thirteen Five" period, the steel industry how to achieve low-carbon green growth? CISA which provides for the development of the industry thinking and guidance. On circular economy development forum held recently, the reporter interviewed the China Iron and Steel Industry Association, the Ministry of Development and Environmental Protection Technology Officer Director Huang.
Reporter: "Thirteen Five" connotation steel industry is what?
Director Huang: "Thirteen Five" connotation steel industry is to achieve green development, is at the end of treatment, the basis of energy saving, clean production, cyclical economy, low carbon economy, industry ecological chain, green manufacturing, taking with steel manufacturing, energy conversion, waste treatment and recycling consumptive functions, with good economic, environmental and social benefits for the development of a new generation of steel flow pattern characteristics.
We have developed the steel industry, "Thirteen Five" green development road map is the system integration sintering production process energy saving technology, systems integration dry flue gas purification and waste heat and pressure utilization technology, systems integration and use of metallurgical slag treatment process waste heat utilization technology, through CDQ, blast furnace dry dust, dry dust converter "three dry" technology, efficient energy transfer and utilization of water resources and efficient recycling, resource efficiency and recycling iron "three use" pollution for efficient processing and sound processing, waste dezincification, waste water desalination, flue gas desulphurization.
Reporter: What are the main iron and steel industry is the development of green innovation direction?
Director Huang: accelerating the transformation and upgrading of traditional manufacturing industry to establish an efficient, clean, low-carbon, recycling, green manufacturing system, the full implementation of green manufacturing. Specific measures include: cyclic process can speed up the generation of process technology research and development, and vigorously promote the development of efficient use of energy with pollution reduction, waste recycling technology and sound processing capabilities, active use of high-efficiency motors, boilers, etc. advanced equipment, with a green and efficient production technology and equipment, improve the traditional manufacturing process, realizing key industry green upgrade; focus on the development of green products and create green supply chain, guide green production and green consumption, strengthen energy-saving environmental monitoring, developing green evaluated.
Reporter: Question steel enterprises develop a recycling economy is facing what?
Director Huang: I think some of the following questions: First, backward production capacity hindered the industry to improve the level of energy saving. Second, the iron and steel enterprise energy use, water use efficiency to be further improved. Between enterprises secondary energy recycling, water use levels vary considerably between the existence of the enterprise imbalances; low-temperature waste heat utilization there is potential to be tapped, the use of unconventional water resources have a greater room for development; energy management water resources management and foreign compared to some gaps. Third, innovation is not high level, innovative environment to be improved. Development of circular economy steel industry breakthrough technology cost, long time, involving a wide range of non-industry can afford a business, we need to inter-State financial support and industry coordination. China, with our own technology innovation capability in the field of enterprise fewer technical level differences, lack of inter-enterprise-driven development potential. Fourth, the cycle of the steel industry and other industries and society needs to be strengthened. Recycling economic eco-industrial chain of the steel industry and building materials, chemicals, electric power and other related industries has not been fully established between. Fifth cycle of economic incentives are not in place. Enterprise use of resources utilization project power generation waste heat and pressure are not valid certification, do not enjoy national awards; slag, tailings and other common cycle of economic and technological lack of financial support, to promote the cause difficulties.
Reporter: "Thirteen Five" during the steel industry how to achieve green growth?
Director Huang: First, to build a number of resource-saving and environment-friendly business model. These enterprises should "zero emissions" as the goal, the construction of three circular chain of the production process. The first is a solid waste recycling chain. Achieve metallurgical slag, iron zinc dust and mud, iron oxide, sintering desulfurization by-products of all solid waste recycling or harmless treatment to form a group of a certain size, a high level of technical equipment, comprehensive utilization rate higher solid waste "zero discharge" enterprise. The second is industrial water recycling chain. From the enterprise management and supervision of water metering start, according to comprehensively promote water rationing; create conditions for the use of water, urban waste water, mine water and brackish water and other non-conventional water resources, increase in wastewater, brine, represented by wastewater treatment and reuse project investment, improve waste recovery. The third is the recycling of secondary energy recycling chain. To promote energy-saving technologies, strengthen CDQ, sintering waste heat recovery, the converter waste heat recovery, heat recovery steam recovery furnace work; improve and promote the transformation of air leakage sintering, blast off the wet blast, gas-steam combined cycle power generation technology; the development of non-blast furnace iron, slag waste heat recycling, reducing gas blast furnace injection cutting-edge technology.
The second is to build a circular economy industrial chain. The depth of integration with other related industries, the steel industry is the fundamental way to the development of circular economy. The steel industry should focus on the needs of downstream users, efforts to develop higher strength, longer life, more environmentally friendly materials, iron and steel weather resistance, corrosion resistance, reducing the consumption of the whole life cycle of steel; steel enterprises and key construction materials, circular economy industrial chain, chemicals, electric power enterprises.
