Abstract

The invention relates to the field of isotope detection and discloses a sampling and sample preparation system and method. The sampling and sample preparation system is arranged in a coal blended biomass power station and comprises a sampling pipeline communicated with a boiler flue of the coal blended biomass power station; a filtering device, a mass-flow controller, a carbon dioxide trap and anexhausting device are arranged on the sampling pipeline in sequence from one end close to the boiler flue to one end far away from the boiler flue. The sampling and sample preparation system further comprises a carbon dioxide transferring device and a carbon-14 testing device; the carbon dioxide transferring device is used for transferring carbon dioxide in the carbon dioxide trap to the carbon-14testing device; the carbon-14 testing device is used for testing carbon-14 metering of carbon dioxide. The sampling and sample preparation system and method can be used for rapidly calculating a blended combustion ratio of the coal blended biomass power station.

Description

Technical field

[0001] The invention relates to the field of isotope detection, and discloses a sampling and sample preparation system and a sampling and sample preparation method. Background technique

[0002] At present, coal is still the main energy source of the power industry. With the development of society and the continuous improvement of economic level, people's demand for electricity has increased sharply, and coal reserves have fallen sharply, while also causing great damage to the natural environment.

[0003] Biomass energy is a kind of carbon-containing renewable energy. Its "carbon neutral" characteristic makes it possible to use biomass energy to replace some fossil energy represented by coal, reduce carbon dioxide emissions and alleviate the greenhouse effect.

[0004] Biomass blended coal combustion is an excellent way to use biomass energy on a large scale. It can not only reduce pollutants and carbon dioxide emissions, but also can efficiently use low calorific va...
