Abstract

The article is devoted to the adjustment of the efficiency of the coke dry quenching plant (CDQP) by installing the subeconomizer in the technological scheme of coke production. A work description is presented of the subeconomizers and analyzes the advantages of the subeconomizers on the existing and new CDQP blocks. It has been emphasized that in coke production one of the most important factors is the need to work all parts of the technological chain with the full productivity. Decreased productivity or disruptions in certain areas can lead to significant losses of the final product. It is shown that the dry coke quenching plant should ensure not only stable operation of the coke battery, but also the required level of coke supply for blast furnace production. Therefore, violation of the technological regime of DCQP can critically affect the production of iron and steel. The feature of dry coke quenching technology is emphasized: the increase in productivity inevitably causes an increase of the temperature of quenched coke. It is shown that one of the ways to maintain the temperature of the quenched coke at the required level is to install a subeconomizer (SE) in the scheme of DCQP. The experience of SE "GIPROKOKS" in designing the reconstruction of existing DCQP is underlined. Data on the operation of the DCQP with the SE included in the technological scheme (which has been successfully operated for more than three years) and without it are given. SE "GIPROKOKS" studies, develops and implements new technologies that can be used in the construction of new coke plants, as well as in the reconstruction of existing ones. It is shown that the use of subeconomizers in dry coke quenching plants allows to increase the productivity of DCQP units on quenched coke by about 10 % while maintaining the required temperature and quality of the obtained coke. Keywords: dry coke quenching, temperature of quenched coke, coke yield, subeconomizer, energy efficiency. Corresponding author S.Yu. Abdullin, е-mail: abdullins1979@gmail.com

提高CDQ机组模块能效的分效器

介绍了焦炭干淬装置在焦炭生产工艺方案中安装亚低温剂对焦炭干淬装置效率的调整。给出了子分类器的工作描述，并分析了子分类器在现有和新的CDQP块上的优点。在焦炭生产中，最重要的因素之一是需要以充分的生产力工作的所有部分的技术链。生产力下降或某些领域的中断可能导致最终产品的重大损失。研究表明，干式焦炭淬火装置既要保证焦炭蓄电池的稳定运行，又要保证高炉生产所需的焦炭供应水平。因此，违反DCQP技术制度会严重影响钢铁生产。强调干焦淬火技术的特点:生产率的提高必然引起淬焦温度的提高。结果表明，在DCQP方案中安装亚低温器(SE)是使焦炭保持在要求温度的方法之一。强调了SE“GIPROKOKS”在设计现有DCQP重建方面的经验。给出了在技术方案中包含SE(已成功运行三年多)和不包含SE的DCQP的运行数据。SE“GIPROKOKS”研究，开发和实施可用于建设新焦炭厂以及重建现有焦炭厂的新技术。结果表明，在干式焦炭淬火装置中使用亚低温剂可使DCQP装置对淬火焦炭的生产效率提高约10%，同时保持所制焦炭所需的温度和质量。关键词:干焦淬火，焦炭温度，焦炭收率，亚低温剂，能效通讯作者:S.YuAbdullin，电邮:abdullins1979@gmail.com
