Abstract

The invention provides a supercritical carbon dioxide explosion monitoring device which comprises a reaction kettle, a heating assembly, a mounting opening, a discharging assembly, monitoring devices, a filler opening and a control valve, wherein the reaction kettle is provided with a pressure bearing cabin and used for storing carbon dioxide; the heating assembly is used for heating carbon dioxide in the pressure bearing cabin; the mounting opening is formed in the reaction kettle and communicated with the pressure bearing cabin; the discharging assembly is provided with a certain pressure bearing value, mounted at the mounting opening in a sealed mode and conducts discharging when the pressure in the pressure bearing cabin reaches the preset value; the monitoring devices are used for monitoring the temperature and pressure of the pressure bearing cabin generated when the discharging assembly is exploded; the filler opening is formed in the reaction kettle, communicated with the pressure bearing cabin and used for injecting carbon dioxide in a sealed mode; the control valve is arranged at the filler opening in a sealed mode. Through cooperation between the control valve and the filler opening, the quantity of injected liquid carbon dioxide can be precisely controlled so that the relationship between the mass of carbon dioxide and the explosion critical temperature can be determined precisely and correspondingly when BLEVE explosion occurs.

Description

technical field [0001] The invention relates to the field of supercritical carbon dioxide parameter monitoring, in particular to a supercritical carbon dioxide explosion monitoring device. Background technique [0002] Carbon dioxide will be in a supercritical state under certain combination conditions of specific temperature and high pressure. At this time, its density is close to that of liquid, and its viscosity is close to that of gas. High density, but easy to flow like a gas, so it is very suitable for oil displacement operations in oil pipelines. [0003] In nature, when the pressure of the liquid in the high-pressure superheated state in the container suddenly drops, the liquid will suddenly gasify and expand in volume, causing the container to explode. When the pressure at the moment of explosion is greater than the pressure before the explosion, a phenomenon is called BLEVE explosion, the explosion medium and burst disc produced by BLEVE explosion will cause great...
