【摘要】：目前我国由重大危险源引发的事故频繁发生,根本原因在于系统的灾变机制不明,研究工作脱离了真实系统,缺乏系统观点和系统思维。本文以颗粒物堆体为复杂系统简化模型,在不同条件下进行实验,探索堆体的坍塌机制。由此提出复杂系统的灾变机制和安全控制方法,在此基础上分析生产系统的事故发生机理,提出生产系统的安全控制模式。将此成果运用于重大危险源的安全管理中,构建重大危险源管理体系,改进重大危险源的辨识、分级和评价技术。主要工作如下:(1)复杂系统灾变机制在本质上可归结为能量耗散的连锁反应机制。本文从外界输入、系统结构、系统边界及一定边界条件下的系统状态等四个因素出发,通过堆体实验探索复杂系统的灾变机制,提出复杂系统的安全控制方法。(2)分析导致系统事故的影响因素及其作用机制,提出生产系统安全控制模式,构建重大危险源管理体系。(3)危险源的辨识、分级和评价工作是重大危险源管理的基础。本文对目前的重大危险源辨识、分级和评价技术进行改进,提出静态—动态相结合的重大危险源分级方法,建立重大危险源评价体系。(4)对某公司的重大危险源进行静态和动态分级,为该公司提出具体的管理建议和安全控制措施。
[Abstract]:At present, accidents caused by major hazard sources occur frequently in our country, the fundamental reason is that the disaster mechanism of the system is unknown, the research work is divorced from the real system, and the lack of systematic point of view and systematic thinking. In this paper, the particle reactor is used as the simplified model of the complex system, and the collapse mechanism of the reactor is explored under different conditions. Therefore, the disaster mechanism and safety control method of complex system are put forward, on the basis of which the accident mechanism of production system is analyzed, and the safety control mode of production system is put forward. The results are applied to the safety management of major hazards, the management system of major hazards is constructed, and the identification, classification and evaluation techniques of major hazards are improved. The main work is as follows: (1) the cataclysm mechanism of complex systems can be essentially attributed to the chain reaction mechanism of energy dissipation. Based on four factors: external input, system structure, system boundary and system state under certain boundary conditions, this paper explores the catastrophic mechanism of complex system through reactor experiment. The safety control method of complex system is put forward. (2) the influencing factors and action mechanism of system accident are analyzed, the safety control mode of production system is put forward, and the management system of major hazard source is constructed. (3) the identification of hazard source, Classification and evaluation are the basis of major hazard management. In this paper, the current identification, classification and evaluation techniques of major hazard sources are improved, and a static and dynamic classification method of major hazard sources is proposed. Establish the evaluation system of major hazard sources. (4) carry on the static and dynamic classification to the major hazard sources of a company, and put forward the concrete management suggestions and safety control measures for the company.
