The utility model discloses a device for automatically analyzing and measuring the content of
methane and
acetylene in
carbon dioxide gas, which comprises a
carbon dioxide adsorption cylinder, an alkali liquor tank, an alkali pump, an alkali liquor measuring cylinder and a display controller, a valve I, a valve II and a valve III are respectively arranged on conveying pipelines which are connected in pairs in the
carbon dioxide adsorption cylinder, the alkali liquor tank and the alkali pump; the conveying pipeline between the carbon dioxide adsorption cylinder and the alkali pump is communicated with the alkali liquor measuring cylinder through a
branch pipeline, the third valve is located on the communicating pipeline between the alkali liquor measuring cylinder and the carbon dioxide adsorption cylinder, and a fourth valve is arranged on the communicating pipeline between the alkali liquor measuring cylinder and the alkali pump. The device for automatically analyzing and measuring the content of
methane and
acetylene in the carbon dioxide gas has the characteristics of high
online analysis speed, high efficiency, high reliability, simplicity in operation, high
automation degree, capability of saving a large amount of manpower and
reagent dosage and the like, can realize
continuous analysis and computerization of
data processing, and is suitable for large-scale popularization and application. And errors caused by human factors are eliminated.
