Problems solved by technology

[0003] In the process of underground construction, the fuel oil in the operation of mechanical equipment will consume the oxygen in the air to produce carbon dioxide. The air tightness is strong, the air fluidity is poor, and the consumed oxygen cannot be replenished, so how to increase the oxygen content of the underground project and reduce the carbon dioxide content is what we need to consider

Abstract

The invention discloses a carbon dioxide absorption device for underground engineering. The carbon dioxide absorption device comprises a shell, a heat dissipation groove is formed in the upper end ofthe shell, a containing cavity, a compression cavity, a liquid storage cavity and a rotating cavity are formed in the shell, the liquid storage cavity is located on the right side of the heat dissipation groove, the compression cavity is located below the liquid storage cavity, and an air groove is formed in the left side of the shell; a protective net is arranged at a groove opening of the air groove, a reaction cavity is formed in the shell and located above the air groove, the rotating cavity is located on the right side of the air groove, and the containing cavity is located on the right side of the rotating cavity. By sucking air at the bottom of the underground passage, carbon dioxide reacts with sodium peroxide to generate oxygen and then is discharged into the underground passage,it is ensured that the oxygen content in the underground passage is sufficient, accumulation of the carbon dioxide is reduced, meanwhile, the generated oxygen is cooled, and the temperature in the underground passage cannot rise.

Description

technical field [0001] The invention relates to the field of underground engineering, in particular to a carbon dioxide absorption device for underground engineering. Background technique [0002] Underground engineering refers to the underground civil engineering that goes deep below the ground to develop and utilize underground space resources. With the development of society and the advancement of civil engineering technology, the development of underground space resources is becoming more and more frequent. During the construction process of underground engineering However, the following problems still exist: [0003] In the process of underground construction, the fuel oil in the operation of mechanical equipment will consume the oxygen in the air to produce carbon dioxide. The air tightness is strong, the air fluidity is poor, and the consumed oxygen cannot be replenished, so how to increase the oxygen content and reduce the carbon dioxide content of underground proje...
