Fluid type trigger and fracturing device

Abstract

The invention discloses a fluid type trigger and fracturing device. A shell and a filling cavity located in the shell are involved. The shell comprises first segments, second segments and connecting joints. The filling cavity comprises a reductant filling cavity body and an oxidant filled cavity body, and the reductant filling cavity body and the oxidant filling cavity body are correspondingly filled with supercritical oxygen and liquid carbonaceous organic materials. The reductant filling cavity body and the oxidant filling cavity body are formed in the first segments and the second segments correspondingly. The two ends of each connecting joint are connected with one ends of the first segments and the second segments correspondingly in threaded and sealed modes or in a seamless welded mode. The other ends of the first segments and the second segments are connected with fluid-filling nozzles and air inflation mechanisms correspondingly. An isolation thermoplastic sheet is mounted in the middles of the connecting joints, a heating wire is mounted in the isolation thermoplastic sheet in a sealed mode, and the heating wire is guided out of the shell through guide lines. The fluid type trigger and fracturing device has the advantages that manufacture cost is low, mixing uniformity of reaction materials is high, heat releasing efficiency is high, and transport safety is good.

Description

technical field [0001] The invention belongs to the technical field of detonators, in particular to a fluid detonator and a cracker. Background technique [0002] Gas blasting technology is to use the vaporization and expansion of easily vaporized liquid or solid substances to generate high-pressure gas, which makes the surrounding medium expand to do work and cause fragmentation. It has the characteristics of no open flame, safety and high efficiency. [0003] Carbon dioxide gas blasters are typical blasting equipment in gas blasting technology, and are widely used in mining, geological exploration, cement, steel, electric power and other industries, subways and tunnels, municipal engineering, underwater engineering, and emergency rescue. [0004] The existing gas blaster mainly includes a vaporization liquid storage pipe and a heating detonator installed in the vaporization liquid storage pipe; the heat generation detonator ignites and generates heat to vaporize easily vap...

AI Technical Summary

Problems solved by technology

[0006] The detonator with the above structure has the following problems: 1. The thermal reactants to be filled in the detonator need to be processed by mixing, mixing, coiling or bagging, and the filling process is time-consuming and labor-intensive. , the manufacturing cost is high; 2. In the process of filling the detonator, the oxidant and reducing agent are prone to uneven mixing, resulting in low heat release efficiency; 3. The thermal reaction material needs to be mixed and filled in advance, and the temperature during transportation is high It is easy to cause combustion or explosion, and has a large safety hazard; 4. Due to the delay of the detonating material or other situations, it is easy to appear the situation of squibs, and it is impossible to judge the cause of the squibs, so the safety cannot be eliminated by rowing the squibs. Hidden danger; 5. The detonation method of the existing gas blaster uses a solid activator to burn to generate high temperature, which directly conducts heat to the liquid carbon dioxide, so that the liquid carbon dioxide gasifies and expands, and the heat absorption efficiency of the liquid carbon dioxide is low; 6. The heat release speed of the detonator Slower, insufficient chemical reaction, low thermal release efficiency, low pressure after liquid gasification, and low blasting power; 7. After blasting, the reactants in the detonator produce a large amount of toxic and harmful gases, such as hydrogen sulfide , sulfur dioxide, nitric oxide and nitrogen dioxide and other gases, which bring relatively large poisonous pollution to the blasting site
