Description

Technical Field

[0001] The utility model relates to the technical field of chemical analysis, in particular to a circulation device applied to a carbon dioxide measuring instrument. Background Art

[0002] In today's world, the task of reducing carbon dioxide emissions is arduous. According to the source of carbon emissions, carbon emissions from cement production enterprises can be divided into direct emissions and indirect emissions. Direct emissions are mainly carbon emissions from cement raw materials, decomposition of carbonates in raw materials and fuel combustion, and emissions are mainly concentrated in the cement clinker burning process; indirect emissions are mainly carbon emissions generated by electricity consumption in various process steps, and direct emission points are mainly concentrated in thermal power plants. According to statistics, direct emissions account for about 98% of the total carbon emissions of cement enterprises, and indirect emissions account for only 2%. Most cement plants use limestone as the calcareous raw material, which is one of the main raw materials for cement production. Limestone raw materials account for about 80% of raw materials. Carbonate decomposition and fuel combustion in cement raw materials will produce carbon dioxide emissions. In order to correctly evaluate the carbon emissions in the cement production process, it is particularly important to detect the carbon dioxide content in cement, cement raw materials, limestone and other materials.

[0003] This requires the use of an infrared carbon dioxide meter. After the phosphoric acid decomposes the sample (such as cement, cement raw material, limestone and other materials), the carbon dioxide gas generated is stored in a closed container (or expansion device), and then subsequent measurements are performed based on the fluidity of the gas. However, in the infrared carbon dioxide meter, if the volume of the closed container is too large, the gas circulation in the bottle will be poor, and if the volume of the closed container is too small, the gas storage capacity will be insufficient, affecting the detection efficiency. Therefore, the utility model proposes a circulation device applied to the carbon dioxide meter to solve the problems existing in the prior art. Summary of the invention

[0004] In view of the above problems, the utility model proposes a circulation device applied to the carbon dioxide measuring instrument. The circulation device applied to the carbon dioxide measuring instrument adds a fan in the container composed of the upper half barrel and the lower half barrel, which promotes the circulation in the whole pipeline, thereby reducing the detection time of the carbon dioxide content in cement and cement raw materials, improving the efficiency of staff, and improving the repeatability and stability of the detection results.
