Abstract

The invention discloses a high-pressure vapor explosion test device and system. The test device comprises a pressure-bearing container, a pressure relief device, a heating device for heating the test medium in the pressure-bearing container, and a sensor, wherein the pressure-bearing container is provided with a cavity consistent with a high-pressure vapor medium injection pipe in inner diameter and is used for providing a load and test place for a high-pressure vapor medium, the side face of the bottom of the pressure-bearing container is provided with a medium injection opening for injecting the test medium into the cavity of the pressure-bearing container, the pressure relief device is of a hollow structure, is arranged at the top of the pressure-bearing container and is connected and communicated with the pressure-bearing container, a rupture disk is arranged in a hollow cavity of the pressure relief device, the sensor is arranged in the cavity of the pressure-bearing container and is used for collecting physical parameters of the test medium in the cavity of the pressure-bearing container. The high-pressure vapor medium injection pipe can be better simulated, the simulation degree of the high-pressure vapor explosion test device is improved, and more reliable technical parameter support is provided for high-pressure vapor explosion test analysis.

Description

technical field [0001] The invention relates to the field of experimental equipment, in particular to a high-pressure steam explosion test device and system. Background technique [0002] Boiling Liquid Expanding Vapor Explosion (BLEVE, Boiling Liquid Expanding Vapor Explosion) refers to a vapor explosion formed by the instantaneous release of a large amount of superheated liquid into the atmosphere. CO 2 When the high-pressure vessel is under the effects of overcharging, overpressure, mechanical shock, thermal stress, corrosion, etc., the material performance is reduced or even the integrity is destroyed, it is entirely possible that serious CO 2 The boiling liquid expands the vapor explosion accident, causing further rupture of the container and complete release of the medium. During oil displacement, CO 2 The pressure inside the injection pipe can reach 30MPa, which is a typical high-pressure equipment, and it has been in the complex environment at the bottom of the we...
