Description

technical field [0001] The invention relates to the technical field of hydrogen flame detection, in particular to a design method of a multi-band red-ultraviolet hydrogen flame detector. Background technique [0002] The consequences of excessive human carbon emissions are becoming more and more serious, and the global climate is getting worse and worse. In response to this situation, various countries have proposed the strategic goal of "carbon neutrality", and clean energy is regarded as an alternative to traditional energy. preferred option. Hydrogen energy is an important part of clean energy. Its product is only water, which is regarded as the cleanest energy. However, the risk of hydrogen energy is its great instability and destructiveness. Hydrogen leakage is easy to generate hydrogen flames, and The hydrogen flame is not obvious in the daytime, and it is not easy to see with the human eye. Once the hydrogen flame ignites the gas storage device, the consequences of e...

Hydrogen energy is an important part of clean energy. Its product is only water, which is regarded as the cleanest energy. However, the risk of hydrogen energy is its great instability and destructiveness. Hydrogen leakage is easy to generate hydrogen flames, while The hydrogen flame is not obvious in the daytime, and it is not easy to see with the human eye. Once the hydrogen flame ignites the gas storage device, the consequences of the explosion will be unimaginable. Therefore, the detection of the hydrogen flame has become an essential safety measure when using hydrogen energy.

Most of the current hydrogen flame detectors are identified by UV signals, but ultraviolet light body multiplier tubes are susceptible to interference from sunlight, specific lights and electric arcs, and are prone to false alarms; a small number of hydrogen flame detectors use infrared signals to identify hydrogen flames, Also because of interference problems, it is prone to false alarms; some hydrogen flame detectors use infrared sensors sensitive to hydrogen flames and ultraviolet light body multiplier tubes to simultaneously identify hydrogen flames, which reduces the corresponding infrared sensors and ultraviolet sensors. False positives, but it can't solve the false positives that both respond, such as halogen lamps, arc welding, etc.
