Problems solved by technology

Once a fire, explosion or leakage of hazardous chemicals occurs, the accident will easily spread, affecting adjacent devices and even adjacent enterprises, causing a catastrophic domino effect accident
Through the analysis of a large number of chemical accidents, it is concluded that 38.6% of chemical accidents will trigger a domino effect, resulting in extremely serious accident consequences
Many traditional quantitative regional risk assessment methods do not consider the domino effect of accidents and the calculation process of accident domino effect analysis is very complicated, so the quantitative regional risk assessment of chemical industry parks is quite difficult

Embodiment Construction

[0043] Such as figure 1 Shown, concrete steps of the present invention are:

[0044] Step 1: Obtain basic data, including hazard type, status, stock, distribution and storage tank type.

[0045] Step 2: Gridding the chemical industry park.

[0046] When the evaluation area is determined, the entire chemical industrial park is divided into two-dimensional spaces in the Cartesian coordinate system (n×m) as shown in Figure 2 by using grids of the same size. Among them, the hazardous chemical storage tanks in the park have been marked. exist figure 1 In , the tank locations can be represented by coordinates (2,5) and (5,9) respectively. If each grid is 100 meters long, then figure 1 The distance between any two grids in can be expressed by their coordinates as follows:

[0047]

[0048] In the formula, d ij is the distance (meters) between grid i and grid j, (x i ,y i ) and (x i ,y j ) are the coordinates of grid i and grid j respectively;

[0049] Step 3: Equipment...

Abstract

The invention relates to a quantitative regional risk calculation method of a chemical park. The method combines the characteristics of the chemical park and the traditional quantitative regional riskassessment model, the gridding method is adopted to reduce the computational complexity of the model, and the domino effect of the accident is taken into consideration. The personal risk value and social risk value of the grid center are calculated by using the risk superposition principle, and finally the personal risk value and social risk value of other regions in the grid are obtained by interpolation method and discrete method. The method of the invention has the characteristics of openness, flexibility, low computational complexity and the like.

Description

technical field [0001] The invention belongs to the field of chemical safety and relates to automation technology, in particular to a method for calculating quantitative regional risks in chemical industry parks. Background technique [0002] With the development of the economy, the scale of the chemical industry is expanding rapidly. The chemical industry is a resource-intensive and high-energy-consuming industry, and there is a large amount of waste water, waste gas, and waste residues, which easily cause environmental pollution. Today, chemical parks have become a new model for the development of my country's chemical industry. Chemical parks are clusters of chemical companies, usually located in economically developed and densely populated areas, characterized by capital-intensive, hazardous chemicals-intensive and equipment-intensive. The construction and development of chemical industry parks not only promote the development of local economy and chemical industry, bu...
