The apparatus for hydrogen fire testing due to electrostatic ignition in plant facility

摘要

The present invention relates to an apparatus for testing of a hydrogen fire caused by static electricity in a plant facility. The apparatus comprises: a test chamber (100) in a plant facility; a hydrogen storage device (220); a hydrogen supply pipe (210), one end of which is connected to the hydrogen storage device (220) and the other end is positioned on one side in the test chamber (100) and is connected to a hydrogen supply nozzle unit (200) discharging hydrogen gas, and which supplies the hydrogen gas in the hydrogen storage device (220) into the test chamber (100); a charging unit (300) which is made of a non-conductor, is separated from the hydrogen supply nozzle unit (200) at a predetermined distance, and blocks an inner cross section of the test chamber (100) such that the hydrogen gas is distributed to only one side of the test chamber (100); a static electricity generator (400) which comes in contact with one surface of the charging unit (300) directed to the hydrogen supply nozzle unit (200) and accumulates static electricity; a ground unit (410) which is made of a conductor, and is positioned to be separated vertically upwards from the hydrogen supply nozzle unit (200) at a predetermined distance; an additional ground unit (420) which is made of a conductor, and is disposed between the ground unit (410) and the hydrogen supply nozzle unit (200); a static electricity measurement device (110) which measures the amount of static electricity of the charging unit (300) horizontally corresponding to the hydrogen supply nozzle unit (200), the ground unit (410), and the additional ground unit (420); and a thermal image camera (120) which checks whether a hydrogen fire occurs by static electricity. Accordingly, it is possible to check whether a hydrogen fire occurs in accordance with the flow rate of hydrogen gas or the concentration of hydrogen gas and the amount of static electricity, and it is possible to reproduce an actual hydrogen fire site.
