Computer Simulation on Industry Pipeline Gas Leakage and Dispersion

In recent years, the staff poison accidents as a result of the Metallurgical industry pipeline gas leakage occur frequently, they have caused the enormous losses for people\´s life and property. One of its important reasons is the people do not really understand the laws of the industry pipeline gas leakage and dispersion, particularly the poisoned injury scope change about gas leakage and dispersion, cannot obtain safety evacuation distance information promptly, thus they have delayed rescue opportunity in the toxicant region, and accidents have caused the heavy casualties and property losses. This paper mainly carries on the numerical simulation about the metallurgical industry gas leakage and dispersion in the air space. Firstly, the author analyzes the laws about the metallurgical industry pipeline gas leakage and dispersion. Secondly, estimates the concentration distribution and the harm scope about gas leakage dispersion. It can provide the scientific basis for the site alert, the personnel emergency evacuation as well as takes the essential remedial measure. It will be helpful to instruct the enterprise to understand promptly the gas leakage dispersion scope and concentration distribution after the gas leakage accident. At the same time, it also will be helpful to instruct personnel to escape from the danger, avoid the gas poisoning or suffocation, and achieve "intrinsic safety" to ensure work safety for the enterprise.
