The invention discloses a system and method for safe discharge of a high-hydrogen natural gas pipeline station, including an upstream main line, a downstream main line, and a station process system. The station process system is provided with an emergency venting system, and the emergency venting system is used for high The hydrogen-containing natural gas station process system realizes rapid pressure relief under emergency working conditions. The emergency venting system is connected to the continuous purging system of the venting pipeline. During operation, it is used to continuously provide a sealed gas source to the venting pipeline, so that the emergency venting system is always in an air-isolated state. When the high-hydrogen-containing natural gas pipeline station is shut down in an emergency, the venting pipeline is closed and the system is continuously purged. And turn on the emergency venting system. Based on the medium characteristics of high hydrogen-containing natural gas with a wide explosion range and high spontaneous combustion probability and the safety guarantee requirements for emergency discharge of the station, the invention forms a safe and economical venting safety guarantee system through the continuous purging system of the venting pipeline and the venting compensation system. Guarantee the safety of emptying.
Description
Technical field [0001] The present invention belongs to the field of hydrogen energy pipeline delivery technology, particularly relates to a high hydrogen containing natural gas pipeline yard safety discharge system and method. Background [0002] Hydrogen energy is recognized as a clean and efficient energy source, affected by the geographical difference between hydrogen energy production and hydrogen energy utilization, medium and long-distance hydrogen energy transmission has gradually become a key link in the efficient utilization of hydrogen energy, of which pipeline transportation is a popular choice and development direction. At present, the more suitable medium and long-distance pipeline transmission modes of hydrogen energy include pure hydrogen pipeline transportation, high hydrogen-natural gas blended pipeline transportation and low hydrogen-natural gas transportation, etc., according to the transmission distance and the adaptable hydrogen energy, natural gas resource...
