【摘要】：当今世界,国际经济环境正处在变革和调整之中,气候变化、能源资源安全等问题越来越被人们所关注,环境保护已成为当今世界普遍关注的热点问题。我国经济经过持续多年的高速增长,在带来空前繁荣的同时,也不可避免地累积了一些环境问题,治理污染,实现废物达标排放是我们当前的一项重要课题。目前,国内大多数企业采用直接燃烧法对废物进行处理。本文以某石化公司丙烯酸酯装置废物焚烧炉为原型,立足于降低燃烧成本,对焚烧炉动力燃料进行替换的关键技术研究。本文查阅了大量国内外研究焚烧炉相关问题的现状及发展趋势,提出了未来焚烧技术的发展方向。结合当下各类燃料特性,研究了用天然气替代原有燃料渣油的可行性,并对天然气调压装置进行了分析和研究,提出了调压撬的设备构成,为保证天然气的压力稳定,满足焚烧炉对燃料的需求提供了一定的理论依据。同时,本文对焚烧炉的关键设备燃烧器进行了分析和研究,并选择在不同天然气负荷下进行冷态实验,为进一步研究开发和优化燃烧器提供了更多的参考信息。另外,本文结合新的燃烧介质和改造后的燃烧设备,对新的工艺进行研究,提出了一系列新的操作要求,实现了装置一次开车成功,满足了生产需要,也为同类装置焚烧炉的改造提供了参考依据,在国内废物焚烧炉设备改进方面具有一定的指导意义。
[Abstract]:In today's world, the international economic environment is in the process of change and adjustment, climate change, energy and resources security and other issues have been paid more and more attention, environmental protection has become a hot issue in the world. After years of rapid economic growth, China's economy has not only brought unprecedented prosperity, but also inevitably accumulated some environmental problems. It is an important issue for us to control pollution and achieve waste discharge up to the standard. At present, most domestic enterprises use direct combustion method to treat waste. In this paper, based on the prototype of waste incinerator in acrylic plant of a petrochemical company, the key technology of replacing power fuel of incinerator is studied based on reducing combustion cost. In this paper, the present situation and development trend of a large number of domestic and foreign research on incinerator related problems are reviewed, and the development direction of incineration technology in the future is put forward. Combined with the characteristics of all kinds of fuels at present, the feasibility of replacing the original fuel residue with natural gas is studied, and the pressure regulating device of natural gas is analyzed and studied, and the equipment composition of pressure regulating pry is put forward in order to ensure the pressure stability of natural gas. It provides a certain theoretical basis to meet the fuel demand of incinerator. At the same time, the key equipment burners of incinerator are analyzed and studied, and the cold experiments are carried out under different natural gas loads, which provides more reference information for further research, development and optimization of burners. In addition, combined with the new combustion medium and the modified combustion equipment, this paper studies the new process, puts forward a series of new operation requirements, realizes the successful start-up of the device at one time, and meets the production needs. It also provides a reference for the retrofit of the incinerator of the same kind of plant, and has certain guiding significance in the improvement of the domestic waste incinerator equipment.
