Abstract

The invention relates to a full-automatic halogen gas measurement device. The device comprises a gas path part and a gas path control part. The gas path part comprises a gas acquisition component, a gas intake time control component and a gas measurement component. The gas acquisition component is used for acquiring a measured gas and air, and conveys the two gases to the gas intake time control component through respective pipelines; the gas intake time control component mixes the two gases through an output pipeline and then conveys the mixed gas to the gas measurement component; the gas measurement component measures the concentration of the mixed gas concentration; the gas path control part includes a control and data processing module and a data display module, the control and data processing module is used for controlling the on-off time of the two gases in the gas intake time control component, receiving an electrical signal fed back by the gas measurement component, performs computing processing on the electrical signal and conveys the processed electrical signal to the data display module. The measurement device provided by the invention realizes real-time on-line measurement of halogen gas from 1ppb to 50ppm, the measurement range is wide and the sensitivity is high.

Description

technical field

[0001] The invention belongs to the field of gas detection, and in particular relates to a fully automatic halogen gas measuring device. Background technique

[0002] Iodine adsorber is the key purification equipment in the nuclear air purification system. It is mainly used in the iodine removal and exhaust system of various nuclear facilities (such as nuclear submarine maintenance bases, reprocessing plants, research reactors, nuclear industry scientific research units, nuclear power plants, etc.). The last barrier to prevent radioactive iodine from entering the surrounding atmosphere under normal operation of nuclear facilities and accident conditions. Therefore, for the newly installed iodine adsorber (arrangement) in the nuclear facility, the on-site leak test must be carried out before operation, and the installed iodine adsorber must be regularly on-site leak test during operation to ensure the function of the iodine adsorber. Effectiveness to ensure t...
