Abstract

The invention discloses an optical fiber hydrogen sensor detection device based on chemical palladium plating, which comprises a spectrograph and a broadband light source, and the spectrograph and the broadband light source are connected with a coupler through optical fibers; the other end of the coupler penetrates through a gas chamber through an optical fiber and is connected with an optical fiber hydrogen sensor arranged in the gas chamber; the air chamber is provided with an air inlet hole; the device further comprises a hydrogen cylinder and a nitrogen cylinder, the hydrogen cylinder and the nitrogen cylinder are connected with a gas flowmeter through pipelines, and a gas outlet of the gas flowmeter is connected with the gas inlet of the gas chamber through a pipeline. The detection device realizes rapid detection of the optical fiber hydrogen sensor.

Description

technical field [0001] The invention relates to the field of hydrogen detection, in particular to a preparation method and detection device of an optical fiber hydrogen sensor based on chemical palladium plating. Background technique [0002] H 2 It is a new energy with high efficiency, environmental protection, abundant reserves, high combustion value, ecological and economic benefits, and provides a way out for solving the dilemma of environmental protection and sustainable economic growth. However, hydrogen has a high diffusion coefficient (0.16cm / s) in air, low ignition energy (0.018mj), high combustion heat (285.8kJ / mol), and a wide range of explosion concentrations (4% to 75%). Explosive gas. There is therefore a potential hazard in the production, storage or transport of hydrogen. In order to reduce the risk of explosion, a technology is needed that can 2 High sensitivity, high precision, fast, real-time, online and remote monitoring of concentration. SUMMARY OF...
