EXPERIMENTAL SYSTEM AND METHOD FOR MEDIUM-LOW-PRESSURE HYDROGEN-CONTAINING PIPELINE

WIPO Patent Application WO/2022/257477

A1

An experimental system and method for a medium-low-pressure hydrogen-containing pipeline, which can more efficiently perform mixing, flow and utilization experiments for a pure hydrogen pipeline and a hydrogen-doped pipeline. The system comprises a mixing device, a medium-low-pressure test pipeline, a control terminal, and a terminal test element connected to the control terminal, wherein the mixing device comprises a plurality of input ports; at least one first input port is in communication with a hydrogen source; at least one second input port is in communication with a non-hydrogen source; an output port of the mixing device is in communication with the terminal test element by means of the medium-low-pressure test pipeline, and is provided with a hydrogen concentration measurement element connected to the control terminal; the medium-low-pressure test pipeline is connected to at least one sensing element connected to the control terminal; and the control terminal controls the pressure and/or flow of the mixing device and the outlet pressure and/or flow of each gas source according to a hydrogen concentration measurement result.
