The Simulation Of The Spread Of Poison Software Development And Application

Papers through a lot of research, on a toxic and harmful substances in the production, storage and transport accidents in the course of the leakage of the status quo as well as poisonous and harmful substances in the production, storage and transport accidents in the course of the leakage on the purpose and significance. At home and abroad poisonous gas or steam-proliferation studies summarized by domestic and foreign poisonous gas or steam leakage model for the spread of contrast, select the Gaussian model as a simulation software model, and applied analysis of the consequences of the accident.In this paper, industrial chemicals were introduced, and its harm to the human body was studied. In this paper, 2001-2006, the domestic accident statistics, that the explosion, poisoning and suffocation are frequent incidents in chemical plants demonstrated in the spread of toxic and harmful substances on the simulation of chemical safety is of far-reaching significance. And through direct leaked to the cause of the accident concluded, summing up the 10 categories often leaked and four kinds of accidents caused by various reasons.Based on the complexity of these models, the amount of computation, this combination of computer technology has been developed based on Visual Basic6.0 the spread of poison simulation software, a decrease of manual calculation. Finally, the software used in the preparation of the case, the liquid chlorine leak through the simulation, and further to liquid chlorine at different atmospheric stability, the release of the source and a high degree of proliferation of surface roughness when summing up the situation was analyzed, and concluded: For the continuous leakage , The leakage rate in certain circumstances, the greater the height of the release of the source and endanger regional smaller atmosphere more unstable, endangering regional smaller regional wind speed greater harm smaller endanger the region mainly in the release of the source The wind direction, wind direction of the harm than perpendicular to the direction of the wind against a range of more than in the same region.
