Abstract

The invention discloses an intelligent electronic activator for a carbon dioxide phase-change cracker. A mounting head and a choke plug are separately arranged at the two ends of an activator housing;a digital delay electronic excitation device is arranged in an inner cavity of the activator housing and the inner cavity of the activator housing is filled up with a heating material; a first guidewire penetrates through the mounting head and then is connected to the digital delay electronic excitation device; and the digital delay electronic excitation device is verified through keys and has adelay electronic excitation function for making the heating material heat up and generate a great deal of reaction gas, thus causing liquid-state carbon dioxide phase change. Being verified through the keys, the electronic activator cannot be activated even obtained without knowing detonating passwords, thus ensuring safety in processes of generation, transportation and storage; and the digital delay electronic excitation device has a delay function, and provides technical support for liquid-state carbon dioxide phase-change delay blasting construction in engineering application.

Description

technical field [0001] The invention belongs to the technical field of blasting devices, in particular to an electronic activator for a carbon dioxide phase change cracker. Background technique [0002] Liquid carbon dioxide phase change fracturing technology has a good application effect in projects such as coal mine gas permeability enhancement, earthwork blasting and excavation. The main principle of this technology is to use the thermal expansion and gasification of liquid carbon dioxide to generate an instantaneous pressure rise, forming an instantaneous high-pressure carbon dioxide gas to destroy coal seams and rock formations. The specific principle is: under certain pressure and temperature conditions, the carbon dioxide gas is pressurized and liquefied, and the liquid carbon dioxide is compressed and canned by the booster pump into the liquid storage tube containing a rupture disc, an activator, and a sealed plug. Take the liquid storage tube, detonator and power c...
