Abstract

The invention provides a dangerous chemical leakage pollution evaluation method. The method comprises the following steps: (1) determining a dangerous chemical dispersion source as an instantaneous leakage source or a continuous leakage source; (2) dividing the source dispersion into heavy gas dispersion and non-heavy gas dispersion of the instantaneous leakage source, and heavy gas dispersion and non-heavy gas dispersion of the continuous leakage source; (3) causing the heavy gas of the instantaneous leakage source to disperse at a concentration meeting a formula shown in the specification; (4) causing the non-heavy gas of the instantaneous leakage source to disperse at a concentration meeting a formula shown in the specification; (5) causing the heavy gas of the continuous leakage source to disperse at a concentration meeting the formula c=b0h0c0 / (bh) in the horizontal direction; (6) causing the non-heavy gas cloud of the continuous leakage source to disperse at a concentration meeting a formula shown in the specification; and (7) determining and displaying the pollution range. The method has the characteristics of accuracy, intuition and the like, is simple to use and can be widely used in the industries of chemical engineering, petrochemical, natural gas and the like.

Description

Assessment method for pollution of hazardous chemical spills technical field The present invention relates to an evaluation method, in particular to a method for evaluating leakage pollution of hazardous chemicals. Background technique In the chemical, petrochemical, natural gas and other industries, there are a large number of toxic and harmful hazardous chemicals. These hazardous chemicals are always in danger of leakage in all aspects of production, transportation, storage and use. Under normal circumstances, in order to facilitate storage and transportation, according to the nature of hazardous chemicals, normal temperature pressurization, low temperature pressurization, etc. are often used for storage. Once the hazardous chemicals leak out, they will form clouds near the ground, causing serious harm to nearby people. With the development of modern industry, the occurrence of hazardous chemical leakage accidents has become more and more frequent, causing huge casualti...
