Inflammable liquid storage inherent danger evaluate method

Abstract

The invention provides a method for assessing the inherent risk of flammable liquid storage, which is based on the characteristics of hazardous chemicals and the risk of dosage, combined with factors such as safe storage distance of hazardous chemicals, chaotic stacking, diffusion of hazardous chemicals, and environmental conditions , using the analytic hierarchy process to realize the inherent risk assessment of hazardous chemicals storage. This patent combines the material danger of hazardous chemicals, starting from the amount of material, safety distance, storage height, etc., can effectively evaluate the overall risk of warehouse layout, is conducive to the rational layout of warehouses, and effectively reduces the overall risk of warehouses through optimization sex.

Description

technical field [0001] The invention belongs to the technical field of petrochemical safety production, and in particular relates to a method for evaluating the inherent risk of flammable liquid storage. Background technique [0002] Tianjin Port Ruihai International Company's "8.12" and Jiangsu Deqiao Storage Co., Ltd.'s "4.22" hazardous chemical warehouse explosion accidents caused huge damage to life, property, and the environment. The problems exposed by the accident include mixed stacking of hazardous chemicals in the explosion area, mixed storage of taboo hazardous chemicals, non-compliance with safety distance requirements, and excessive stacking, which lead to energy enrichment of explosives and continuous explosions. [0003] China's roads transport about 200 million tons of dangerous goods every year. At present, while the output of hazardous chemicals continues to increase, the overall supply of hazardous chemicals is in short supply. In addition, the layout of st...

Problems solved by technology

The problems exposed by the accident include mixed stacking of hazardous chemicals in the explosion area, mixed storage of taboo hazardous chemicals, non-compliance with safety distances, and excessive stacking, which lead to energy enrichment of explosives and continuous explosions

[0003] China's roads transport about 200 million tons of dangerous goods every year. At present, while the output of hazardous chemicals continues to increase, the overall supply of hazardous chemicals is in short supply. In addition, the layout of storage facilities is unreasonable, leading to illegal operators. "Black warehouse" operating without a license

[0004] "Identification of Major Hazard Sources of Hazardous Chemicals" (GB18218-2009) is a national standard for evaluating whether hazardous chemicals meet major hazard sources. Such an evaluation result cannot reflect the mixed stacking of hazardous chemicals, the safety distance does not meet the requirements, nor can it reflect the characteristics of the diffusion of hazardous chemicals and the characteristics of the storage environment. It cannot truly realize the quantitative evaluation of hazardous chemicals storage and cannot truly reflect the goal of hierarchical supervision.

[0005] In order to solve the problem that the existing assessment methods do not include safety distance, chaotic stacking, diffusion of hazardous chemicals and environmental conditions into the scope of assessment, this patent will develop a method for assessing the inherent risks of flammable liquid storage, which will be more targeted and more accurate. Accurately characterize the hazardous characteristics of flammable liquid hazardous chemical warehouses, and guide enterprises to carry out hierarchical management and control
