The gaseous hydrogen leakage detection device in the hydrogen storage station

摘要

Topic The gaseous hydrogen is detected with non-contact detection technique, the device which can monitor the presence of the gaseous hydrogen leakage in the hydrogen storage station even from the remote post is offered.SolutionsIt has optical multipath reflection section 3 in the gaseous hydrogen leakage supervisory field, it detects with the sensor section 5 which is installed in the position where Raman scattered light of the hydrogen origin which is generated by the laser light which is made to reflect multiplex in the space which is indwelling in the said optical multipath reflection section, is retired from the gaseous hydrogen leakage supervisory field. With this configuration as not needing anti-explosive armament the gaseous hydrogen leakage detection device in the hydrogen storage station is created. Choice figure Drawing 2
