Explosive devices for pressurized detonation of high-pressure gases or liquids or supercritical fluids

Abstract

The invention relates to an exploder for exploding high-pressure gas or / and liquid or supercritical fluid through pressurization, which comprises a high-pressure-resistant container, a heating source body or a pressurizing body and a filling substance, wherein the heating source body or the pressurizing body is internally or externally arranged at any side wall or the lower part of the high-pressure-resistant container of the exploder; at least an explosion slice or pressure release valve is arranged in the high-pressure-resistant container; the gas or liquid or supercritical fluid in the high-pressure-resistant container is pressurized by adopting a self-mounted heat source or an external pressurization device, thus the explosion slice is fractured when the gas or the liquid capable of being gasified or the supercritical fluid is released from the high-pressure-resistant container to reach the control pressure of the selected explosion slice or pressure release valve; the high-pressure gas in the high-pressure-resistant container rapidly bursts out, thereby realizing the explosion of the high-pressure gas; no naked fire exists; the high-pressure-resistant container can bear high pressure and high temperature and can be repeatedly used, thereby lowering the cost; no polluted gas or chemical substance is released to be friendly and safe to the environment; the explosion pressure is controlled by the explosion slice or pressure release valve; and the exploder is applied to various occasions which apply explosives and is particularly convenient to use in coal mines or mines with gas outburst.

Description

technical field [0001] The invention belongs to the field of explosive devices and relates to an explosive device for boosting and detonating high-pressure gas or liquid or supercritical fluid. Background technique [0002] At present, blasting mainly adopts 1. All kinds of explosions are caused by gunpowder and fuel. The explosion simultaneously produces open flame, high temperature and high pressure gas. In many working applications, open flame will cause the danger of fire hazard. High temperature will cause damage to many materials. At the same time, the explosion pressure is cannot be accurately controlled. 2. There are also heating plastics or inflatable containers to heat and expand the contents of the container until the container ruptures and release high-pressure gas. However, it is difficult for an inflatable container to withstand high pressure, and the position of releasing gas cannot be controlled. When installing an inflatable container, open it. The size of ...

[0002] At present, blasting mainly adopts 1. All kinds of explosions are caused by gunpowder and fuel. The explosion simultaneously produces open flame, high temperature and high pressure gas. In many working applications, open flame will cause the danger of fire hazard. High temperature will cause damage to many materials. At the same time, the explosion pressure is uncontrollable

2. There are also heating plastics or inflatable containers to heat and expand the contents of the container until the container ruptures and release high-pressure gas. However, it is difficult for an inflatable container to withstand high pressure, and the position of releasing gas cannot be controlled. When installing an inflatable container, open it. The size of the blast hole cannot be grasped, so it has no practical application value
