【摘要】：危险化学品生产企业中危险源辨识与安全管理对策是当前行业生产中需要解决的首要问题,对其中各类具体项目的危险源辨识及安全管理对策研究势在必行。本课题针对危化品生产企业中典型的氢氧站项目开展危险源辨识和安全对策管理研究,以具体正在运行中的氢氧站项目为例,在深入了解水电解制氢工艺的流程及特点的基础上,结合项目具体所处区域、季节特点、平面布置、消防依托、运行工况等基本情况,分析氢氧站项目存在的危险、有害因素,列举出氢氧站项目中危险、有害物料种类,以及电解间、减压阀间、汇流排间、储罐区存在的火灾、爆炸、灼烫、机械伤害等多种危险性,并根据重大危险源辨识标准,对其是否构成重大危险源开展辨识;在采用LEC法对项目危险源辨识与评价的基础上,针对其危险程度较大的电解槽、储罐以及碱液箱应用装置危险度评价法再次进行分析评价,采用事故后果模拟分析法,对其发生爆炸的危险程度进行定量分析评价,同时对可能发生的危险化学品事故后果进行了预测,全方位辨识项目存在的风险和隐患,在此基础上,通过二阶模糊安全评估方法建立评估体系,将影响氢氧站项目安全运行的基本情况、工艺设备设施、危险源辨识管理及其他因素四个方面同安全现状联系起来,系统反映出各项因素对氢氧站项目运行的影响,最终从物的不安全因素和人的不安全因素两个方面入手,提出控制危险源,消除、预防安全隐患的安全对策措施,把危险控制在可接受程度内,避免出现危险化学品重大事故,同时为企业提高企业的安全管理水平。
[Abstract]:The identification of dangerous sources and the countermeasures of safety management are the most important problems in the production of hazardous chemicals. It is imperative to study the risk source identification and safety management countermeasures for various specific projects. This subject aims at the typical hydrogen and oxygen station projects in dangerous chemicals production enterprises to carry out research on hazard source identification and safety countermeasures management. Taking the project of hydrogen and oxygen station in operation as an example, on the basis of deeply understanding the process and characteristics of water electrolysis hydrogen production process, combining with the specific area, seasonal characteristics, plane layout, fire protection support, operating conditions and other basic conditions of the project, This paper analyzes the hazards and harmful factors of hydrogen and oxygen station projects, enumerates the hazard, the kinds of harmful materials, and the fire, explosion and burning of electrolytic room, pressure reducing valve room, busbar room, storage area, etc. Based on the identification criteria of major hazard sources, whether they constitute major hazard sources or not, and on the basis of the identification and evaluation of project hazard sources by using LEC method, aiming at the electrolytic cells with high risk degree, The hazard assessment method of storage tank and lye tank is used to analyze and evaluate the risk degree of explosion again, and the accident consequence simulation analysis method is used to quantitatively evaluate the risk degree of explosion. At the same time, the possible consequences of hazardous chemical accidents are predicted, and the risks and hidden dangers of the projects are identified in all directions. On this basis, the evaluation system is established by the second-order fuzzy safety assessment method. The basic conditions affecting the safe operation of the hydrogen and oxygen station project, the process equipment and facilities, the hazard source identification management and other factors are connected with the safety status quo. The system reflects the influence of various factors on the operation of the hydrogen and oxygen station project. Finally, from the aspects of unsafe factors of objects and unsafe factors of human beings, the paper puts forward the safety countermeasures to control the dangerous sources, eliminate and prevent the hidden dangers of safety, and control the risks within the acceptable level, so as to avoid the occurrence of major accidents of dangerous chemicals. At the same time for enterprises to improve the level of safety management.
