【摘要】：隨著能源需求增加,“十一五”期末全國火電廠裝機容量較“十五”期末翻了一番。超過96%的燃煤電廠脫硫設(shè)施采用石灰石-石膏濕法脫硫工藝,由此其工業(yè)副產(chǎn)物-脫硫石膏的數(shù)量也在不斷快速增加。據(jù)統(tǒng)計全國燃煤電廠脫硫石膏年產(chǎn)量現(xiàn)已突破8000萬噸,且以年貯存堆放量2000萬噸的速度增加。目前燃煤電廠脫硫石膏利用率不高、綜合利用附加值低,已成為電力行業(yè)固廢治理領(lǐng)域面臨的一個新的環(huán)保問題。綜合利用率低主要有兩個方面的原因：一是技術(shù)方面,燃煤電廠脫硫石膏在含水率、氯離子含量、白度、抗壓強度等方面與建材行業(yè)綜合利用還有一定差距,脫硫石膏綜合利用基礎(chǔ)性、前瞻性技術(shù)研發(fā)投入不足,技術(shù)裝備落后,缺乏技術(shù)產(chǎn)品檢測等標準。二是政策方面,現(xiàn)有省級及國家政策向脫硫石膏產(chǎn)業(yè)傾斜力度和激勵扶持力度均不夠,相關(guān)政策法規(guī)以指導意見、財稅政策為主,缺少具體的獎懲和監(jiān)督管理辦法,亟需出臺系統(tǒng)全面的產(chǎn)業(yè)政策。 本文以省級區(qū)域(江蘇)為典型研究對象,首先通過調(diào)研、摸底調(diào)查等手段掌握江蘇省燃煤電廠脫硫石膏的排放及綜合利用情況,通過實驗分析脫硫石膏理化特性,提出綜合利用技術(shù)途徑。為后續(xù)技術(shù)經(jīng)濟方案和政策分析提供基礎(chǔ)；其次通過開展已有石膏標準比對分析、技術(shù)經(jīng)濟和技術(shù)政策等相關(guān)內(nèi)容分析研究,在此基礎(chǔ)上提出了燃煤電廠脫硫石膏利用對策的可行性途徑和合理方案,并有針對性的提出了相關(guān)政策建議。
[Abstract]:With the increase of energy demand, the installed capacity of thermal power plants at the end of the 11th Five-Year Plan has doubled compared with the end of the Tenth Five-Year Plan. More than 96% of the desulfurization facilities in coal-fired power plants adopt limestone gypsum wet desulfurization process, so the number of desulfurized gypsum, the industrial by-product, is also increasing rapidly. According to statistics, the annual output of desulphurized gypsum in coal-fired power plants has now exceeded 80 million tons, and the annual storage and stacking capacity has increased at the rate of 20 million tons. At present, the utilization ratio of desulfurization gypsum in coal-fired power plant is not high and the added value of comprehensive utilization is low, which has become a new environmental protection problem in the field of solid waste treatment in power industry. There are two main reasons for the low comprehensive utilization ratio: first, in terms of technology, desulfurization gypsum in coal-fired power plants still has a certain gap with the comprehensive utilization of building materials in the aspects of water content, chloride ion content, whiteness, compressive strength, etc. The comprehensive utilization of desulphurization gypsum is basic, the investment of prospective technology research and development is insufficient, the technical equipment is backward, and the standard of technical product detection is lacking. Second, in terms of policy, the existing provincial and national policies are not enough in favour of desulfurization and gypsum industry, and the relevant policies and regulations are based on guidance, fiscal and taxation policies, and lack of specific measures for rewards and punishment and supervision and management. A systematic and comprehensive industrial policy is urgently needed. This paper takes the provincial area (Jiangsu) as the typical research object. Firstly, by means of investigation and mapping, the discharge and comprehensive utilization of desulphurization gypsum in Jiangsu coal-fired power plant are grasped, and the physical and chemical characteristics of desulfurization gypsum are analyzed through experiments. The comprehensive utilization of technology is put forward. To provide the basis for subsequent technical and economic programs and policy analysis. Secondly, through carrying out comparative analysis of existing gypsum standards, technical, economic and technical policies and other related content analysis and research, On this basis, the feasible approach and reasonable scheme of desulfurization gypsum utilization in coal-fired power plant are put forward, and relevant policy suggestions are put forward.
