Convenient-to-convey carbon dioxide fracturing device

Abstract

The invention discloses a convenient-to-convey carbon dioxide fracturing device. The convenient-to-convey carbon dioxide fracturing device comprises a gas release block, a gas guide block, a liquid storage pipe, a heating pipe and a filling valve, a liquid storage cavity is formed inside the liquid storage pipe, one side of the liquid storage cavity is fixedly provided with the heating pipe, the side, close to the heating pipe, of the liquid storage pipe is fixedly provided with the filling valve through threads, and the side, far away from the heating pipe, of the liquid storage pipe is further fixedly provided with the gas guide block through threads. According to the convenient-to-convey carbon dioxide fracturing device, an anti-skid grip is arranged at the front end of the carbon dioxide fracturing device so that the fracturing device can be prevented from moving in a blast hole, meanwhile, a gas release port is formed so that gas can be sprayed along a preset trajectory, moreover, a sound absorption material is attached to the inner wall so that noise generated during blasting can be reduced, a dust suppressant bag is arranged at the front portion of a gas channel so that a dust suppressant can be driven through spraying of the gas to be sprayed, then generation of blast dust is inhibited, and a damping assembly is arranged on the side wall of the liquid storage pipe so that hard collision of an external environment to the liquid storage pipe in the transportation process can be reduced.

Description

Technical field [0001] The invention relates to the field of blasting technology, in particular to a carbon dioxide cracker that is convenient for transportation. Background technique [0002] Under the action of external excitation energy, the liquid carbon dioxide will change from liquid to gas, and the liquid-gas phase change occurs, and the volume expands. By controlling the size of the excitation energy and the timing of the liquid-gas phase change, the carbon dioxide gas medium can be instantly expanded to produce mechanical energy. Do work, the mechanical energy acts on the rock mass, which can realize the phase change expansion of carbon dioxide to break the rock. At the same time, the thermal reaction process of the carbon dioxide cracker is carried out in the inner cavity of the closed tube. The low temperature blasting, the emitted CO2 has the effect of suppressing explosion and flame retardant. It will detonate gas, and the vibration is small, and it does not produce ...

AI Technical Summary

Problems solved by technology

[0002] Under the action of external excitation energy, liquid carbon dioxide will change from liquid state to gaseous state, a liquid-gas phase transition will occur, and the volume will expand. By controlling the magnitude of the excitation energy and the timing of the liquid-gas phase transition, the carbon dioxide gas medium can be instantly expanded to generate mechanical energy. Work, the mechanical energy acts on the rock mass, which can realize the phase change expansion of carbon dioxide to break the rock. At the same time, the thermal reaction process of the carbon dioxide cracker is carried out in the inner cavity of the closed tube. The low-temperature blasting, the ejected CO2 has the effect of suppressing explosion and flame retardancy, and does not It will detonate the gas, and the vibration is small, does not produce destructive shocks or shock waves, greatly reduces the probability of inducing gas outburst, does not produce toxic and harmful gases, and has a short hiding distance, can quickly return to the working face, continuous operation, the existing carbon dioxide It is difficult to fix the cracker in the blast hole, and there is a hidden danger of slipping out. At the same time, when the carbon dioxide is ejected from the hole, it will generate a lot of noise and cause a large amount of dust to be raised. At the same time, during transportation, the liquid storage pipe needs to be Protect against hard collisions from the external environment
