【摘要】：危險化學(xué)品生產(chǎn)企業(yè)中危險源辨識與安全管理對策是當(dāng)前行業(yè)生產(chǎn)中需要解決的首要問題,對其中各類具體項目的危險源辨識及安全管理對策研究勢在必行。本課題針對�；飞a(chǎn)企業(yè)中典型的氫氧站項目開展危險源辨識和安全對策管理研究,以具體正在運行中的氫氧站項目為例,在深入了解水電解制氫工藝的流程及特點的基礎(chǔ)上,結(jié)合項目具體所處區(qū)域、季節(jié)特點、平面布置、消防依托、運行工況等基本情況,分析氫氧站項目存在的危險、有害因素,列舉出氫氧站項目中危險、有害物料種類,以及電解間、減壓閥間、匯流排間、儲罐區(qū)存在的火災(zāi)、爆炸、灼燙、機械傷害等多種危險性,并根據(jù)重大危險源辨識標(biāo)準(zhǔn),對其是否構(gòu)成重大危險源開展辨識;在采用LEC法對項目危險源辨識與評價的基礎(chǔ)上,針對其危險程度較大的電解槽、儲罐以及堿液箱應(yīng)用裝置危險度評價法再次進行分析評價,采用事故后果模擬分析法,對其發(fā)生爆炸的危險程度進行定量分析評價,同時對可能發(fā)生的危險化學(xué)品事故后果進行了預(yù)測,全方位辨識項目存在的風(fēng)險和隱患,在此基礎(chǔ)上,通過二階模糊安全評估方法建立評估體系,將影響氫氧站項目安全運行的基本情況、工藝設(shè)備設(shè)施、危險源辨識管理及其他因素四個方面同安全現(xiàn)狀聯(lián)系起來,系統(tǒng)反映出各項因素對氫氧站項目運行的影響,最終從物的不安全因素和人的不安全因素兩個方面入手,提出控制危險源,消除、預(yù)防安全隱患的安全對策措施,把危險控制在可接受程度內(nèi),避免出現(xiàn)危險化學(xué)品重大事故,同時為企業(yè)提高企業(yè)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.
