Description
Technical Field
The utility model relates to a biogas collecting device, in particular to a biogas collecting device for a refuse landfill.
Background
The garbage buried in the garbage burying place can generate a large amount of methane in an anaerobic environment, and the methane can be collected, stored and reused as an energy source. At present, the biogas collection mode that landfill site adopted is mostly gas guide gabion collection mode, and this mode is collected marsh gas and is shown certain limitation. Along with the prolonging of the service time, the stone gaps in the gas guide stone cage and the gas inlet holes on the floral tubes for collecting gas are gradually closed by substances such as sludge and the like. And because the air guide gabion is positioned in the landfill in a landfill mode, the air guide gabion can hardly be maintained in the process of operating a refuse landfill. The gas guide gabions are arranged in a manner that most of the gas guide gabions lose the biogas collection effect finally and fall into a layout in the application practice of the refuse landfill, the gas guide gabions do not really play a role in guiding and recycling biogas, biogas resource waste is caused, and the construction cost of the biogas collection device is wasted. Consequently, design a section and can effectively prevent that the stone material clearance in the air guide gabion and the inlet port on the gas collecting pipe from being sealed, blockking up, ensure that marsh gas collection device can effectively move for a long time, and the effective rubbish landfill yard marsh gas collection device who carries out the continuation collection to the marsh gas that the rubbish landfill place produced is the utility model discloses a research purpose.
SUMMERY OF THE UTILITY MODEL
To the problem that above-mentioned prior art exists, the utility model provides a landfill marsh gas collection device, this landfill marsh gas collection device can effectively solve the technical problem that above-mentioned prior art exists.
The technical scheme of the utility model is that:
the utility model provides a landfill marsh gas collection device, includes air guide gabion and gas collecting pipe, the air guide gabion comprises wire netting cage cladding centimeter stone, the center department of air guide gabion is provided with corresponding locating hole perpendicularly, the gas collecting pipe run through set up in the central point of air guide gabion puts, and gas collecting pipe runs through evenly distributed on the position in the air guide gabion and is provided with a great deal of corresponding inlet port, the periphery of air guide gabion and the lateral wall of gas collecting pipe are provided with the corresponding outside filtration wire netting and the inboard filtration wire netting of one deck respectively, outside filtration wire netting and inboard filtration wire netting with the rigid coupling has a great deal of evenly distributed's buffer spring respectively between the air guide gabion, and outside filtration wire netting and inboard filtration wire netting with it has corresponding filtering layer material to fill respectively between the air guide gabion.
The filter layer is made of corrosion-resistant polyurethane filter sponge.
The gas collecting pipe adopts an HDPE pipe with the outer diameter of 200mm and the wall thickness of 11.9 mm.
The upper end of the gas collecting pipe is connected with a corresponding exhaust pipe in a sealing mode, and a corresponding exhaust valve is installed at the gas inlet end of the exhaust pipe.
The air exhaust pipe is connected to an external methane treatment pool through a corresponding air exhaust fan and an exhaust pipe.
The utility model has the advantages that:
the utility model discloses a periphery of air guide gabion and the lateral wall of gas collecting pipe are provided with the corresponding outside of one deck respectively and filter wire netting and inboard filtration wire netting, and the outside filters the wire netting and the inboard filters the buffer spring that the rigid coupling has a great deal of evenly distributed respectively between wire netting and the air guide gabion, and it has corresponding filtering layer material to fill respectively between wire netting and inboard filtration wire netting and the air guide gabion to filter the outside. The outside filters the wire netting and the inboard filters the wire netting and forms elastic framework between buffer spring and the air guide gabion through a plurality of evenly distributed, is similar to the skeleton of mattress, when having sufficient holding power, still has the cushioning effect, makes the utility model discloses a filter layer material can exist smoothly in the landfill rubbish. The filter layer material is effectively ensured to keep the original fluffy state, and the air permeability is not influenced while the filtering effect on the sludge is effectively ensured. The filtering material filled between the outer filtering wire net and the air guide gabion has large area, and can effectively ensure enough air permeability on the basis of the area of the sludge attachment part; the area of the filter material filled between the inner side filter wire netting and the air guide stone cage is smaller, but the amount of sludge penetrating into the space between the inner side filter wire netting and the air guide stone cage is small, so that enough air permeability can be still ensured. Effectively ensure the utility model discloses a practicality.
The utility model discloses a filter layer material is corrosion-resistant polyurethane filter sponge. One ensures the utility model discloses a filter layer material has sufficient life, and two fluffiness and the surface irregularity that can realize the filter layer material make mud can't attach comprehensively on the filter layer material, effectively further improve the utility model discloses a practical function.
The device can effectively prevent the stone gaps in the gas guide gabion and the gas inlet holes in the gas collecting pipe from being sealed and blocked, ensures that the methane collecting device can effectively operate for a long time, and effectively collects the methane generated in the refuse landfill continuously, thereby improving the utilization rate of methane resources and improving the economic benefit.
