Background technology
Refuse landfill gas refers in the garbage loading embeading process, piled up or the domestic waste of landfill in contained large amount of organic, the gas that generates through microbiological anaerobic digestion, degraded.Rubbish landfill gas is a kind of mist, and its generation and release are by conditional decisions such as the water regime in the component of rubbish, soot, rubbish temperature, pH value, meteorological condition, rubbish age, soot structure and environmental geologies.Rubbish landfill gas has multiple release approach: on the one hand can be by the landfill yard surface to the unordered diffusion of atmosphere; On the other hand, landfill gas can be by the geological structure in the underground ground,, landfill gas is moved to from the ground of landfill yard away from discharge into just now atmosphere to the transverse horizontal diffusion mobility of landfill yard surrounding area such as crack etc.And a lot of refuse landfills were being made vertical shaft, and the latter half is old rubbish, and gas production is relatively poor, and the first half is new rubbish, and gas deliverability is strong, how can the old and new's rubbish all be used, and reduce cost, were very important problems.Cover layer between the old and new's rubbish often affects the level of making above and collects well, and the landfill gas that the old rubbish in bottom produces can not well be collected.How forming a connecting link, the old and new's rubbish is all effectively used, improve the gas deliverability in soot, is the thinking of the utility model patent.
The utility model content
The purpose of this utility model is: for overcoming the deficiencies in the prior art, provide a kind of tubing type landfill gas level simple in structure, easy to use to collect well.
The technical solution of the utility model is: a kind of tubing type landfill gas level is collected well, include the real pipe of gas collecting level, the horizontal floral tube of gas collecting, the vertical floral tube of gas collecting, the three-dimension vegetative net lattice, well-head valve, be connected with at least two the vertical floral tube of gas collecting on the horizontal floral tube of described gas collecting, the place of being cross-linked of the vertical floral tube of described gas collecting and the horizontal floral tube of gas collecting is the tubing type structure, one end of the horizontal floral tube of gas collecting is the sealed end of sealing, the other end is connected with the real pipe of gas collecting level, the collection well master collection conduit that the real pipe of the horizontal floral tube of gas collecting and gas collecting level consists of is the tilting structure, the angle of main collection conduit tilting structure and horizontal plane is α, the vertical height of the horizontal floral tube sealed end of gas collecting and horizontal plane is greater than the vertical height of gas collecting level real pipe external part and horizontal plane, the real pipe of gas collecting level external part port is provided with a three-way connection, three-way connection is left, right two horizontal ends are connected with the well-head valve of being connected collection well collection flow with the real pipe of gas collecting level respectively, and the downward port of three-way connection is connected with drainage arrangement.
Drainage arrangement includes two vertical tubes and a root bottom part communicating pipe, two riser upper end are that open type, bottom are the linker structure by being communicated with bottom communicating pipe, two vertical tubes are not contour structure, and the downward port of the higher riser upper end of two vertical tube middle tube bodies upper ends relative level face height and three-way connection is connected.
The horizontal floral tube of gas collecting and the vertical floral tube of gas collecting are hdpe pipe, are provided with through hole at body, are coated with one deck three-dimension vegetative net lattice outside the horizontal floral tube of described gas collecting and the vertical floral tube of gas collecting.

Positive beneficial effect of the present utility model
The horizontal collection well construction technique of tubing type landfill gas of the present utility model is simple, Completed advance rate is fast, construction technology is ripe, environmental suitability is strong, gas collection is effective, make things convenient for percolate to discharge, the maintenance expense is low, reduce rubbish landfill gas dissipation, collect well arranges maneuverability.
Description of drawings
Fig. 1 is main TV structure schematic diagram of the present utility model.
Number in the figure 1 is overlying soil, and label 2 is the horizontal floral tube of gas collecting, and label 3 is the vertical floral tube of gas collecting, label 4 is the real pipe of gas collecting level, and label 5 is three-way connection, and label 6 is well-head valve, label 7 is drainage arrangement, and label 8 is Aerated Landfill Layers, and label 9 is the three-dimension vegetative net lattice.
The specific embodiment:
Referring to Fig. 1, a kind of tubing type landfill gas level is collected well, include the real pipe 4 of gas collecting level, the horizontal floral tube 2 of gas collecting, the vertical floral tube 3 of gas collecting, three-dimension vegetative net lattice 9, well-head valve 6, be connected with at least two the vertical floral tube of gas collecting on the horizontal floral tube 2 of gas collecting, the vertical floral tube 3 of gas collecting is the tubing type structure with the place of being cross-linked of the horizontal floral tube 2 of gas collecting, horizontal floral tube one end of gas collecting is that initiating terminal is the sealed end of sealing, the other end is connected with the real pipe 4 of gas collecting, the real pipe 4 of the horizontal floral tube 2 of gas collecting and gas collecting level is the integral type structure and is integral inclination formula structure, the angle of tilting structure and horizontal plane is α, wherein 15 °≤α≤60 °.The vertical height of horizontal floral tube 2 sealed ends of gas collecting and horizontal plane is greater than the vertical height of gas collecting real pipe 4 external parts and horizontal plane, such structure has guaranteed in the pipe that penetrating fluid can discharge and can not overstock in body, the real pipe of gas collecting level external part port is provided with a three-way connection 5, two horizontal ends of three-way connection 5 middle left and rights are connected with the well-head valve 6 of being connected collection well collection flow with the real pipe 4 of gas collecting level respectively, and port downward in the three-way connection 5 is provided with drainage arrangement.Drainage arrangement includes two vertical tubes and a root bottom part communicating pipe, two riser upper end are that open type, bottom are the linker structure by being communicated with bottom communicating pipe, two vertical tubes are not contour structure, and port downward in the higher riser upper end of its middle tube body upper end relative level face height and the three-way connection is connected.The water that flows down of incline structure overflows by the drainage arrangement of connected vessels type like this.
