Movable carbon dioxide storage tank used for coal mine

Abstract

The invention discloses a movable carbon dioxide storage tank used for a coal mine, and relates to the technical field of carbon dioxide storage equipment. The movable carbon dioxide storage tank usedfor the coal mine comprises a movable frame and a storage tank body arranged on the movable frame. Ladder frames are fixedly arranged on the two sides of the upper end of the movable frame. A pushinghandle is fixedly arranged at one end of the movable frame. An air compressor is fixedly arranged above the storage tank body. A connecting pipe is fixedly connected between the air compressor and the storage tank body. An electromagnetic valve is fixedly arranged on the side face of the connecting pipe. According to the movable carbon dioxide storage tank used for the coal mine, the storage tankbody, the connecting pipe, an air pressure sensor, the air compressor, the electromagnetic valve and a control processor are arranged so that the air pressure in the storage tank body can be monitored, regulated and controlled in real time and is kept stable; and the situation that liquid carbon dioxide stored in the storage tank body is gasified due to the fact that the air pressure in the storage tank body is lower than a preset value range is prevented, and the liquid carbon dioxide can be better stored in the storage tank body.

Description

technical field [0001] The invention relates to the technical field of carbon dioxide storage equipment, in particular to a mobile carbon dioxide storage tank for coal mines. Background technique [0002] Coal mines are areas where human beings exploit coal resources in coal-rich mining areas, and are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far away from the surface, it is generally selected to excavate the coal by digging the roadway underground, which is an underground coal mine. When the coal seam is very close to the surface, it is generally chosen to directly strip the surface soil layer to excavate coal. This is an open-pit coal mine. In order to meet the needs of the coal mining industry, it is necessary to use storage tanks to store liquid carbon dioxide to prevent fires in the mine. [0003] However, the air pressure in the traditional carbon dioxide storage tank for coal mines cannot be monitored and regulated i...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a kind of mobile carbon dioxide storage tank for coal mine, to solve the above-mentioned background technology that the air pressure in the traditional carbon dioxide storage tank for coal mine cannot be monitored and regulated in real time, and the air pressure in the storage tank cannot be in a stable state. When the air pressure is lower than the preset value, the liquid carbon dioxide stored in the storage tank is easy to vaporize, and due to the lack of protective devices, the storage tank device shakes too much during the movement and is easily damaged, which affects the storage effect of carbon dioxide.
