Embodiment Construction

[0039] Such as figure 1 As shown, a simulation experiment system for a hot and poisonous disaster environment includes pipelines, which are sequentially divided into a driving section 11 , a driven section 12 , a horn-shaped expansion section 13 , a test section 14 , and a wave elimination section 15 . The inner diameter of the driving section 11, the inner diameter of the driven section 12, and the inner diameter of the end of the expansion section 13 near the driven section 12 are all the same, and the diameter of the end of the expansion section 13 away from the driven section 12 is larger than the diameter of the driven section 12. . The driving section 11 and the driven section 12 are connected through a clamping membrane structure 25, and the clamping membrane structure 25 is provided with an explosion-venting membrane. The expansion section 13 and the test section 14, and the test section 14 and the wave-elimination section 15 are all connected by flanges, and sealing ...

Abstract

The invention belongs to the field of disaster environment simulation system, and particularly relates to a simulation experimental system for disaster environment of fire, explosion and poison, the simulation experimental system comprises an explosive shock wave generating device arranged at one end of a pipeline, a fire high-temperature generation device and a poisonous gas / particles environmentgeneration device which are arranged on the middle of the pipeline, and pipeline where the fire high-temperature generation device and the poisonous gas / particles environment generation device arranged is taken as a testing section of the simulation experiment system. The advantages of the simulation experimental system for disaster environment of fire, explosion and poison are that: a compound disaster experiment environment is provided, by providing with the explosive shock wave generating device, the fire high-temperature generation device and the poisonous gas / particles environment generation device on the pipeline, disaster environments with explosive shock waves, poison substances and high temperature can be simulated, guidance of human body injury mechanism and individual protection technical requirement in the disaster environment of fire, explosion and poison, and selection of appropriate emergency equipment for hazardous chemical practitioners are provided, and finally a purpose of protecting life safety of people is achieved.

Description

technical field [0001] The invention relates to the field of disaster environment simulation systems, in particular to an explosive and poisonous disaster environment simulation experiment system. Background technique [0002] During the production, storage, transportation, and use of hazardous chemicals, leakage accidents of hazardous chemicals are prone to occur due to unsafe behaviors of people, unsafe conditions of objects, and irresistible environmental factors. If the hazardous chemicals themselves have the characteristics of flammability, it is very easy to form a compound disaster environment of fire, explosion and toxic substances during the leakage process. [0003] A human body burn death risk assessment system and method in a fire environment disclosed by the Hefei Public Security Research Institute of Tsinghua University (application number: CN201610298559.6); the Third Affiliated Hospital of the Third Military Medical University of the Chinese People's Liberati...
