Embodiment 1
[0044] Example 1 Explosion accident of a hydrogen chloride storage tank in a chemical plant
[0045] The example is described as follows: It is proposed that in July 2009, a dangerous goods storage tank in a chemical factory in a certain district of Beijing exploded. The dangerous stored substance was hydrogen cyanide, and the dangerous goods storage capacity was 50 tons. Obtain the NCEP global forecast background field data in June 2009, run the atmospheric circulation numerical simulation and forecast model, obtain the meteorological field conditions in June 2009, and extract and convert the required meteorological element data. Input information such as the simulation range and simulation time, and at the same time obtain the accident information of the real-time monitoring equipment and perform data conversion to generate a simulation parameter file.
[0046] Run the hazard emission estimation model, the gas three-dimensional diffusion model, the post-processing program of...
