Embodiment Construction

[0022] The embodiment will be further described with reference to the accompanying drawings.

[0023] A carbon dioxide cracker, referring to figure 1 with figure 2 , which is mainly composed of three parts, namely filling head 110, liquid storage pipe 111 and release head 112. The liquid storage pipe 111 is provided with a communication port 114 connected with the filling head 110, and the liquid storage pipe 111 is provided with There is a release groove 115 connected to the release head 112, and a connecting channel 116 communicating with each other is provided between the release groove 115 and the interior of the liquid storage chamber. The filling head 110 is provided with a horizontal first cavity 212 and a vertical cavity. The second cavity 213 is provided, the first cavity 212 communicates with the outside world and the liquid storage chamber respectively, and the second cavity 213 communicates with the outside world and the first cavity 212 respectively, and the sec...

Abstract

The invention discloses a carbon dioxide fracturing device which comprises a charging head, a liquid storing pipe and a release head which are sequentially arranged. A storage cavity is arranged in the liquid storing pipe, a communication opening for communication is arranged between the charging head and the liquid storing pipe, a release groove allowing the release head to be embedded therein is arranged on the liquid storing pipe, and a connecting channel is formed between the release groove and the storage cavity and is provided with an air outlet mechanism; and an inlet mechanism is arranged on the charging head, the air outlet mechanism comprises a guide hole located at the inner wall of the connecting channel and communicated with the outside, and a switch assembly is arranged at the position of the guide hole. The problems that when the carbon dioxide fracturing device is washed, pipe washing gas is wasted, and the interior of the carbon dioxide fracturing device is not thorough in washing are solved.

Description

technical field [0001] The present invention relates to cracker technology, more specifically, it relates to a carbon dioxide cracker. Background technique [0002] At present, as the country's safety and environmental protection requirements for mines and quarries are getting higher and higher, the supervision of explosives is becoming more and more stringent. Since the filling of the carbon dioxide cracker in use only takes 1-3 minutes, and the whole process from initiation to completion only takes 0.4 seconds, its expansion force can reach 2500T, which can effectively expand the cracking area within 1.2m from the volley surface In rock formations with a rock hardness > 12 degrees Platts, the fracture gap can reach 50mm, and the blasting cylinder can be safely reused, so the promotion and use of its technology has been put on the agenda. The carbon dioxide in the carbon dioxide cracker exists in a liquid state below 31 degrees Celsius or under high pressure, and it sta...
