Problems solved by technology

[0005] However, the heat-generating material used in the current carbon dioxide cracking blasting method has less heat generation, so that the liquid carbon dioxide cannot be rapidly expanded and blasted, resulting in a longer blasting time. A large amount of dust and noise are generated when the wall is blown, which affects the entire blasting process

Abstract

The invention relates to the technical field of carbon dioxide fracturing, in particular to a carbon dioxide fracturing device and a heating material and using method thereof. The carbon dioxide fracturing device comprises a discharge pipe with multiple exhaust holes, a liquid storage pipe, a heating device and a rotating device are arranged in the discharge pipe, the heating device is arranged in the liquid storage pipe and connected with the rotating device, and the rotating device is arranged at the end of the liquid storage pipe so that the heating device can evenly heat carbon dioxide in the liquid storage pipe. The two ends of the liquid storage pipe are provided with a gland and an energy release valve, and the gland is provided with a rotating device through hole penetrating through the upper end face and the lower end face of the gland. Liquid carbon dioxide in the liquid storage pipe is heated by heating the heating material, the liquid carbon dioxide is gasified and expanded, a shearing piece is broken through mechanical energy generated when the liquid carbon dioxide is gasified and expanded to a certain pressure, and the effects of being low in labor intensity, free of open fire, large in fracturing power, safe and efficient are achieved.

Description

technical field [0001] The invention relates to the technical field of carbon dioxide cracking, in particular to a carbon dioxide cracker and its heating material and usage method. Background technique [0002] With the development of urban underground railways in my country and the continuous maturity of urban subway networks, subway stations and lines usually contain pile structures, and manual excavation of piles is required for construction. When the artificial excavation pile encounters a rock layer with high hardness, it will adopt the method of manual and mechanical excavation, or the method of explosive blasting. The former construction is difficult, the work efficiency is low, and there is great safety when people work underneath. Risk, the latter pollutes the environment, the process is cumbersome, unsafe and costly. [0003] High-pressure gas blasting is a kind of blasting without explosives. In the early 1960s, some developed countries such as the United States ...
