Study Of Source Intensity Back-calculation For Non-heavy Gas Leakage

With the increasing number of producers of hazardous chemicals and storageunits, an increasingly large scale, sudden leakage of dangerous chemicals are alsoincreasing, resulting in more and more serious injuries. In dealing with suddenleakage of dangerous chemicals, leakage affected area clear of personnel and majorevacuation and transfer of property is the primary means of emergency, and todetermine the source of strength is the key source of information leakage problemsolving. China’s current strong inverse problem for the source type heavy gas leakhazardous chemicals has made some achievements, compared to non-heavygas-based sources of hazardous chemicals leaking strong inverse problem alsoinvolved less. Therefore, this article is to explore the heavy gas-based non-hazardouschemical leak source strong inverse methods work as follows:1.Assuming a non-heavy gas leakage model, and set its source powerful littleas2kg/s, wind speed of1.5m/s, atmospheric stability class is weakly unstable.Gaussian plume dispersion model as the theoretical basis, Matlab software as ameans for the assumption of non-heavy gas-leakage and diffusion of hazardouschemicals carried forward simulation.2.heavy gas-based analysis of non-hazardous chemicals leaking gas leakageand diffusion concentration distribution and characteristics, combined with Matlabsimulation to identify the relationship between leakage and leakage of gasconcentration distribution between strong stream of seeking inverse method, theconcentration-based detection value stream of strong anti-leakage calculation.3.inverse model for improvement, selection and distribution of analyticaldetection point detection point calculations affect the accuracy of the results of theinverse.In this paper, heavy gas-based non-hazardous chemicals for the study,application software Matlab diffusion leakage forward simulation and sourcestrength of the reverse calculation, its conclusions may be non-source strong inverse heavy gas type of hazardous chemical spills methods provide a reference, and theselection and distribution methods to detect reference points are non-emergencyrescue process heavy gas-hazardous chemical spills in.
