An apparatus for collecting landfill gas is provided to collect and discharge the landfill gas generated from a landfill efficiently, thereby preventing environmental contamination due to the landfill gas and utilizing the landfill gas as fuel, by using a gas collecting pipe with gas input holes. An apparatus for collecting landfill gas comprises a gas collecting pipe(10) vertically buried in a landfill to collect the landfill gas, a gas transport pipe connected horizontally to the gas collecting pipe to transport the landfill gas, power facilities for receiving the landfill gas from the gas transport pipe through selective operation of a valve to use the landfill gas as fuel, and a gas discharging unit for receiving the landfill gas through selective operation of the valve to purify the landfill gas and discharge the purified gas. The gas collecting pipe has a plurality of gas input holes(11) formed on an outer circumferential surface thereof. A screw(12) is spirally installed on the outer circumferential surface of the gas collecting pipe so that the gas collecting pipe is easily rotated and buried in the landfill. Further, the plurality of gas input holes is projected at the gas collecting pipe, and a filter net for preventing impurities from flowing in is installed at forward part of the plurality of gas input holes. |
