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

Embodiment example

[0090] The inherent risk assessment method of flammable liquid storage provided by the present invention is to characterize the dangerous characteristics of hazardous chemical warehouses more specifically and accurately, and combine the safety Based on factors such as distance, chaotic stacking, diffusion of hazardous chemicals, and environmental conditions, the AHP is used to realize the inherent risk assessment of hazardous chemical storage. The specific implementation cases are as follows:

[0091] S1: Determine the warehouse: select a petrochemical enterprise 1000m 2 The hazardous chemicals warehouse stores gasoline, totaling 480t;

[0092] S2: Select evaluation unit i: the gasoline stored in the warehouse is divided into 80 units;

[0093] S3: Substance hazard M1i, i={0, 1, ---n}, where n is the maximum number of substance units, where n=80: Refer to Attached Table 1, gasoline substance hazard is 16;

[0094] S4: special substance hazard M2i, i={0, 1, ---n}, where n is ...

Abstract

The invention provides an inflammable liquid storage inherent danger evaluate method; on the danger chemical characteristic and dosage danger basis, the method combines the danger chemical storage safety distance, chaotic stacking, danger chemical diffusion and environment condition factors, and uses the hierarchy analysis method to evaluate the danger chemical storage inherent dangers. The method considers the danger chemical substance dangers, the substance amount, the safety distance and storage height, thus effectively evaluating the warehouse arrangement integral danger, reasonably deploying the warehouse, and effectively reducing the warehouse integral danger through optimizations.

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...
