PURPOSE: A system for monitoring the discharging state of landfill gas based on a vertical-well-multi-monitoring-cap(VWMMC) is provided to detect the abnormality of a gas collecting pipe and a landfill gas transferring conduit based on a gas collecting pipe state monitoring part and a landfill gas transferring conduit monitoring part. CONSTITUTION: A system(10) for monitoring the discharging state of landfill gas based on a VWMMC includes a gas collecting pipe state monitoring part, a landfill gas transferring conduit monitoring part, and a landfill gas shutoff valve(60). The gas collecting pipe state monitoring part is in connection with a gas collecting pipe and the landfill gas shutoff valve. The gas collecting pipe state monitoring part includes a temperature and pressure measuring port(51) and a sampling port(52). The landfill gas transferring conduit monitoring part is in connection with a landfill gas transferring conduit(30) and the landfill gas shutoff valve. The landfill gas transferring conduit monitoring part includes a temperature and flux pressure measuring port(71) and a sampling port(72). The landfill gas shutoff valve shuts off the flow of landfill gas between the gas collecting pipe state monitoring part and the landfill gas transferring conduit monitoring part. |
