Problems solved by technology

This sampling and sample preparation process not only takes a long time, but also the captured carbon dioxide will inevitably be polluted by atmospheric carbon dioxide during the storage period before and after alkaline absorbent capture, which makes the carbon-14 abundance test results of flue gas samples difficult. deviation

Abstract

The present invention provides a graphitization device, a sampling and sample preparation system and a sampling and sample preparation method. The graphitization device is provided with a sample tubefor storing a flue gas sample, wherein CO2 and CO in the flue gas sample are reduced into graphite in the sample tube; and the sample tube is provided with: a gas inlet for introducing the flue gas sample into the sample tube, and an exhaust port used for exhausting the flue gas sample from the sample tube. The graphitization device can realize gas washing and sampling through opening and closingof the gas inlet and the gas outlet, and CO2 and CO in the flue gas sample stored in the sample tube are finally converted into graphite in a positive pressure environment.

Description

technical field [0001] The invention relates to the field of isotope detection, in particular to a graphitization device, a sample preparation system and a sample preparation method. Background technique [0002] With the development of society and the improvement of human living standards, the demand for energy supply has increased. Under the background of sustainable development and green development, with the decline of fossil energy reserves, new requirements are put forward for the supply of energy. [0003] Biomass energy is a "carbon neutral" renewable energy. The technology of directly burning biomass fuel into the furnace for power supply has been very mature in China. Foreign experience shows that using existing coal-fired boilers to co-fire biomass is a better way to utilize biomass energy. This combustion method can not only improve the power generation efficiency of biomass fuel, but also save the investment cost of the infrastructure of biomass direct-fired ...
