Abstract

The invention discloses a hydrogen leakage monitoring device which comprises a mounting assembly, a gas collection assembly and a monitoring assembly, a flange plate and a pressing plate of the mounting assembly are connected through a plurality of fastening screws, a connecting pipe of the gas collection assembly is connected with the flange plate, and a water pressure adjusting shell and a gas shell are sequentially communicated with the connecting pipe. A liquid suction pipe of the monitoring assembly penetrates through the gas shell, a rotating rod is rotationally connected with the gas shell, a sealing plate is arranged, and an observation window is installed on one side of the gas shell. The flange plate and the pressing plate are matched to be connected with a system needing to be monitored, then cooling liquid enters a water pressure adjusting shell through a connecting pipe, the sealing plate is opened, hydrogen continues to rise to enter the gas shell so that the air pressure in the gas shell can be increased, and the increased air pressure can push sealing liquid in the gas shell to enter the liquid suction pipe, and the height can be observed through the observation window, so that the leakage condition can be intuitively obtained, and maintenance can be carried out in time.

Description

technical field [0001] The invention relates to the technical field of gas leakage monitoring, in particular to a hydrogen leakage monitoring device. Background technique [0002] At present, the hydrogen cooler of the generator in the power plant is usually cooled by circulating cooling water. In order to prevent the cooling water from leaking into the generator, the generator factory usually requires the pressure on the hydrogen side to be higher than the pressure on the water side. Therefore, if the heat exchange of the hydrogen cooler If the pipe leaks, the hydrogen may leak to the cooling water side, and then enter the entire cooling water system, including the hydrogen near the cooling water pump and other motors, the dangerous area will be greatly expanded, threatening the safety of the unit equipment and the safety of the unit operation. Safety accidents are prone to occur. Contents of the invention [0003] The object of the present invention is to provide a hydr...
