Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen compressor interlock control, in particular to a safety interlock control system suitable for a diaphragm hydrogen compressor. Background Art

[0002] When using GD134-135 / 10-220 diaphragm hydrogen compressors and GD4-135 / 10-220 diaphragm hydrogen compressors to compress high-pressure hydrogen at hydrogen stations, there are risks such as fire, explosion, poisoning, and suffocation if a safety emergency occurs. When actions such as rapid shutdown, venting, cutting off the gas source, and sounding the alarm are required, they are all manual, step-by-step operations. This has disadvantages such as multiple operational processes, complex operations, long distances to each point, and long time consumption. Furthermore, hydrogen is a flammable and explosive gas with high pressure, and there are multiple large hydrogen storage tanks not far from the hydrogen compressors. This makes chain reactions very likely, leading to massive casualties and property damage within a 100-meter radius. A safety interlock control system suitable for diaphragm hydrogen compressors is needed to address this issue. Utility Model Content

The linkage fire control module 4 is connected to a measuring instrument probe 5 and an audible and visual alarm 6. The audible and visual alarm 6 is connected to a PLC control module 3. The measuring instrument probe 5 is composed of a hydrogen probe, a flame probe, a smoke probe, an infrared probe, and an ultrasonic probe. An automatic valve 9 is connected to the PLC control module 3, and the automatic valve 9 is respectively installed at the connecting pipes of the hydrogen storage tank outlet 10, the hydrogen compressor inlet 11, and the hydrogen compressor exhaust port 12;

[0022] In this embodiment, the interlocking fire control system is composed of a field measuring instrument probe 5 and an emergency sound and light alarm 6. When an abnormal situation is detected, a signal is sent to the security interlock module 7 of the interlocking fire control module 4 in the safety interlock control system.

[0023] In specific applications, the safety interlock control system in this device consists of three parts: a hydrogen compressor monitoring module 13, an on-site automatic valve 9, and a linkage fire control module 4. The hydrogen compressor 1 operation monitoring system uses a PLC control module 3 as the control core and an industrial computer 2 as the display operation interface. Its main functions are to monitor the on-site operation data of the hydrogen compressor, control the operation of the equipment, and trigger emergencies. The on-site automatic valve 9 is set, and the manual valves at the hydrogen storage tank outlet 10, the hydrogen compressor inlet 11, and the hydrogen compressor exhaust port 12 are changed to self-operated pneumatic diaphragm valves, pulse valves, and pneumatic valves according to actual safety requirements.
