A detection system and detection method applied to a hydrogen distribution station

Abstract

The invention discloses a detection system and a detection method applied to a hydrogen distribution station, and relates to the field of hydrogen detection. A detection system applied to a hydrogen distribution station, comprising a hydrogen separation device, a hydrogen collection device, an exhaust gas collection device, an optical cavity ring-down spectrometer, and a host computer. The hydrogen separation device has a particle sampling chamber. In the present invention, the hydrogen gas is separated by the hydrogen gas separation device, the separated hydrogen gas is collected by the hydrogen gas collection device, the tail gas in the hydrogen gas separation device is collected by the tail gas collection device, and the particulate matter is collected by the particle sampling chamber. The upper computer calculates the hydrogen concentration according to the quality of collected hydrogen and the total amount of gas passed into the hydrogen separation device, and identifies the type of exhaust gas and particulate matter through infrared spectroscopy. In this way, the hydrogen concentration of the hydrogen source can be detected, and the gas type and particulate matter doped in the hydrogen source can be identified, so as to realize the identification of the impurities in the hydrogen source, and then reasonably distribute them to the corresponding demand side .

Description

technical field [0001] The invention relates to the field of hydrogen detection, in particular to a detection system and a detection method applied to a hydrogen distribution station. Background technique [0002] Hydrogen distribution station, also called hydrogen station, is used to distribute hydrogen from different sources to different demand industries. In the hydrogen production industry, there are many ways to prepare hydrogen. The common industrial production methods include water gas method, electrolysis of water and electrolysis of saturated salt water. Due to different hydrogen preparation methods, different incidentals will be produced. Although the hydrogen production plant will carry out filtration and purification before transporting to the hydrogen distribution station, it will still be mixed with a certain amount of by-products or particulate matter generated during transportation, such as the water gas method. Doped with nitric oxide by-products, electroly...
