Abstract

The invention discloses a methane mixed gas purification device on the basis of chemical reaction and a method for applying the methane mixed gas purification device. The methane mixed gas purification device comprises a methane collection and purification mechanism, a methane mixed gas drying and layering mechanism and a methane storage mechanism. A gas outlet end of the methane collection and purification mechanism is connected with a gas inlet end of the methane mixed gas drying and layering mechanism, and a gas outlet end of the methane mixed gas drying and layering mechanism is connectedwith a gas inlet end of the methane storage mechanism. The methane mixed gas purification device and the method have the advantages that the methane mixed gas purification device is simple in structure and reasonable in design, coal mine methane mixed gas can be purified by the methane mixed gas purification device, the methane utilization efficiency can be improved, methane pollution can be reduced, and the like.

Description

technical field [0001] The invention belongs to the technical field of coal mining, and in particular relates to a chemical reaction-based gas mixture gas purification device and a use method thereof. Background technique [0002] The main components of the mixed gas emitted from coal mines are gas, nitrogen, carbon dioxide, oxygen, and water vapor. Since the concentration of gas mixture discharged from coal mines is often affected by factors such as underground coalbed methane content, coal mining, and ventilation volume, the concentration of gas mixture varies greatly. If separation and purification are performed, the energy consumption will far exceed the energy for obtaining gas. It is very uneconomical. In addition, its concentration and flow rate are unstable, and it is difficult to be used as an energy source. Therefore, for a long time, the mixed gas emitted from coal mines can only be used for combustion or air discharge, resulting in huge energy waste and environme...
