【摘要】：循环经济作为一种促使资源、环境与经济协调发展的先进发展模式成为兰炭产业进行产业结构调整的必然选择。目前,循环经济的研究与实践在我国逐步展开。将循环经济的理念与我国兰炭产业实际相结合,寻求兰炭产业技术改造途径,优化兰炭企业产业链具有重要的战略意义。长期以来,兰炭产业一直都是较为粗放的经济发展方式,某些企业或者地方为追求经济利益,只注重局部和短期目标,不合理发展兰炭产业从而引发了更为严峻的资源与环境问题,兰炭产业实现可持续发展必须走循环经济的道路。论文以循环经济理论、清洁生产理论、产业关联理论为指导,深入分析国内外煤炭行业循环经济发展现状,采用文献分析、实地调查、综合比较的方法,在对我国兰炭产业发展现状、产业结构、生产工艺、资源利用方式等进行充分调研分析的基础上,分析兰炭产业发展循环经济的潜力,以循环经济和清洁生产为指导思想和最终目的,提出兰炭企业进行技术改造的途径。本文的主要研究结论为： (1)目前兰炭生产主要采用低温干馏工艺,常用的低温干馏炉型多为三江型内热式直立炭化炉,各种干馏炉都有其各自的优缺点和不同的适应条件。兰炭产业的生产规模逐渐扩大,经济效益不断提高,但其资源利用率仍然较低。 (2)通过分析研究,兰炭产业发展循环经济的潜力很大,兰炭产业发展循环经济能提高资源的利用率、减少污染物的排放量、提高经济效益。 (3)兰炭产业发展循环经济,可以通过延伸产业链、产业链耦合、推行清洁生产、进行技术改造等方式,提高兰炭产业的循环经济水平。 (4)实例研究表明,兰炭企业进行技术改造带来了一定的效益：①延伸了企业产业链,提高了产业链的稳定性；②焦炉煤气全部得到利用,提高了资源的利用率；③废弃物得到循环利用,减少了污染物的排放量；④增加了产品附加值,提高了企业的经济效益。因此,基于循环经济理念对兰炭企业进行技术改造,符合可持续发展的要求,能提高企业的循环经济水平,提高企业的综合效益。
[Abstract]:Recycling economy as an advanced development model that promotes the coordinated development of resources, environment and economy has become an inevitable choice for the industrial structure adjustment of orchid charcoal industry. The research and practice of circular economy have been carried out step by step in our country. The idea of circular economy is combined with the actual situation of blue charcoal industry in China to seek the way of technical transformation of blue charcoal industry. It is of great strategic significance to optimize the industrial chain of blue charcoal enterprises. For a long time, the orchid charcoal industry has been a relatively extensive economic development mode, some enterprises or places in pursuit of economic interests, only focus on local and short-term goals. The unreasonable development of orchid charcoal industry leads to more severe problems of resources and environment. The sustainable development of blue charcoal industry must follow the road of circular economy. Under the guidance of circular economy theory, cleaner production theory and industry correlation theory, the paper deeply analyzes the present situation of circular economy in coal industry at home and abroad, and adopts the methods of literature analysis, field investigation and comprehensive comparison. On the basis of full investigation and analysis of the present situation, industrial structure, production technology and resource utilization mode of the orchid charcoal industry in China, the potential of the blue charcoal industry to develop circular economy is analyzed. With circular economy and cleaner production as the guiding ideology and the ultimate aim, the paper puts forward the ways of technical transformation in the orchid charcoal enterprises. The main conclusions of this paper are as follows: At present, the low temperature dry distillation process is mainly used in the production of blue carbon. The common low temperature dry distillation furnace type is Sanjiang type inner heat type vertical carbonization furnace. All kinds of dry distillation furnaces have their own advantages and disadvantages and different adaptive conditions. The production scale of the orchid charcoal industry has gradually expanded and the economic benefits have been continuously improved, but the utilization ratio of its resources is still relatively low. 2) through analysis and research, it is found that there is great potential for the development of recycling economy in orchid charcoal industry. The development of recycling economy in orchid charcoal industry can improve the utilization of resources, reduce the discharge of pollutants and increase economic benefits. 3) the development of circular economy in orchid charcoal industry can improve the recycling economy level of orchid charcoal industry by extending industry chain, coupling industry chain, promoting cleaner production, and carrying out technological transformation. The case study shows that the technical transformation of the orchid charcoal enterprise has brought about certain benefits: 1 has extended the industrial chain of the enterprise and improved the stability of the industrial chain; (2) the coke oven gas is all utilized and the utilization ratio of resources is improved; (3) waste is recycled and the discharge of pollutants is reduced; (4) the added value of products is increased, and the economic benefit of the enterprise is improved. Therefore, the technical transformation of the orchid charcoal enterprise based on the concept of circular economy can meet the requirements of sustainable development and can improve the level of circular economy of the enterprise. Improve the comprehensive benefits of enterprises.
