The embodiment of the invention provides an explosion overpressure assessment method, which comprises the following steps of: establishing a plurality of explosion overpressure curve relation diagrams corresponding to explosion gas cloud volumes and explosion source distances under different explosion source intensities; according to the intensity of an explosion source, matching an explosion overpressure curve relation graph corresponding to the intensity of the explosion source; and according to the volume of the explosion gas cloud and the distance between the point location and the explosion source, finding the explosion overpressure of the point location from the explosion overpressure curve relation graph. The invention further provides an explosion overpressure evaluation device. According to the technical scheme, the complex calculation process of explosion overpressure can be avoided, the analysis speed is increased, and large errors caused by an empirical judgment method are avoided.
Description
technical field [0001] The present invention relates to the field of safety technology, in particular to an explosion overpressure evaluation method, an explosion overpressure evaluation device and a corresponding storage medium. Background technique [0002] There are a large number of process devices in petrochemical enterprises, and their explosion overpressure needs to be calculated when performing process layout, risk assessment, and safety protection. Calculation of explosion overpressure is a complex task, which requires a large amount of data and complex simulation calculations. It is difficult for general engineers and technicians to master, so it is not suitable for the preliminary safety analysis of a large number of devices distributed in petrochemical enterprises. [0003] MEM (Multi-Energy Method, multi-energy method) is a typical scaling explosion prediction model. It is a vapor cloud explosion effect prediction model established based on a large number of ex...
