Honeycomb type cement collecting pipe for landfill gas biogas and leachate

Technical Field

The utility model relates to the technical field of garbage treatment, and particularly discloses a honeycomb type cement collecting pipe for garbage landfill gas biogas and leachate.

Background

The garbage pollutes soil, atmosphere and water, which not only affects the ecological environment of people, but also endangers the living environment of people. Landfill is still the most main method for solving the problem of the household garbage in most cities in China, and 85% of the urban household garbage is subjected to landfill treatment. The landfill technology is characterized by simple operation and capability of treating all kinds of garbage. But the floor area is large, and serious secondary pollution exists, for example, the ground water and soil can be polluted by garbage leachate, the air quality around the site is seriously affected by odor generated by garbage stacking, and in addition, methane gas generated by garbage fermentation is not only fire and explosion hidden trouble, but also can generate greenhouse effect after being discharged into the atmosphere.

The traditional landfill gas biogas and leachate collecting and guiding mode has the following defects:

1) The existing HDPE high-density polyethylene pipe has high cost, is easily affected by the gravity of garbage and silt to generate extrusion deformation and fracture, and blocks the collection and discharge of the air passage and leachate;

2) The Q235 steel pipe type collection is easy to corrode, the steel cost is extremely high, the steel pipe is heavy, the honeycomb holes are machined and are required to be installed by means of heavy mechanical equipment such as a crane fork truck, the installation difficulty is high, the efficiency is low, the effort of manpower, material resources and financial resources is increased, the cutting slag and burrs generated when the steel pipe is used for oxygen cutting the gas collection holes are easy to cause the defects that the leakage liquid is easy to cause the hook of garbage slag to cause the blockage in a pipeline and the like;

3) The landfill gas biogas reinforcement cage is easily corroded due to the acidity of leachate, deformation and collapse of the reinforcement cage are easily caused along with the flowing of landfill leachate, collection of landfill gas biogas is affected, recycling is not easy, construction difficulty is high, labor cost is greatly increased, collection efficiency is low, and the like.
