Abstract

The invention provides an intelligent chemical industry park canned substance explosion influence analysis method. The method comprises the following steps: S1, calculating the explosion energy Q of a medium contained in a storage tank according to the attribute of the medium contained in the storage tank and storage tank container parameters; S2, converting the explosion energy Q into TNT equivalent QTNT, wherein the QTNT is explosion energy released by explosion of a medium contained in the storage tank; S3, executing a simulation experiment, igniting and detonating the Q0 amount of TNT explosive at a safe open position, and recording the distance R0 from the target to the explosion center and the shock wave overpressure P0 of the corresponding distance; S4, fitting a unary multiple curvilinear equation of the shock wave overpressure P0 with respect to the distance R0; S5, calculating the simulation ratio alpha of the medium explosion energy Q to the simulation experiment TNT explosive energy; S6, traversing the critical value of the impact wave overpressure on the damage level of the human body or/and the building, and solving the corresponding distance R under each damage level. The method for analyzing the explosion influence of the canned substances in the intelligent chemical industrial park has the advantage that the safety awareness of the chemical industrial park is improved conveniently.

Description

technical field [0001] The invention relates to the technical field of safety supervision and management in intelligent chemical industry parks, in particular to a method for analyzing the impact of canned material explosions in intelligent chemical industry parks.
