Description
Technical field
This utility model relates to the processing equipment of a kind of rubbish landfill gas, particularly a kind of shallow embedding horizontal well method rubbish landfill gas
Collection system.
Background technology
Traditional waste disposal method has landfill method, composting process and burning method.Landfill method is by rubbish after classification, will
Some can natural decomposition rubbish by landfill by the way of, embedment underground carry out fermentation decompose.Garbage loading embeading remains me at present
State most cities solves the main method of house refuse outlet, and at present, most domestic waste uses at landfill
Reason.
In the stacking and catabolic process of rubbish, substantial amounts of rubbish landfill gas, this gas can be produced under the effect of antibacterial
Containing methane in body, carbon monoxide and sulfide, not only produce stink, pollute environment, increase the interior pressure of rubbish heap, cause rubbish
Rubbish moves dislocation, even collapses.And it or inflammable gas, when they run up to finite concentration in waste layer, even can
Initiation fire and blast.
The processing mode of traditional rubbish landfill gas uses vertical shaft method to collect, as it is shown in figure 1, imbed one before dumping
Root VERTICAL TUBE 4, by buried for the collecting pipe inside at rubbish heap 5, or is stratified and set in the different degree of depth, the rubbish collected
Landfill gas, by collecting pipe 6, VERTICAL TUBE 4, is delivered to main trachea 1 after bend pipe 3, main trachea is provided with air valve.Described receipts
Collector is the straight tube with a lot of pore, also becomes floral tube.This rubbish landfill gas collection mode of tradition, needs in rubbish heap to bury
If a lot of pipelines, structure is complicated, and the gap between rubbish is easy to make rubbish landfill gas escape, and the actual collection rate of gas is not
Foot 40%.
Summary of the invention
Technical problem to be solved in the utility model is: providing a kind of simple in construction, cost is relatively low, and collection and confinement of gases rate is relatively
High rubbish landfill gas collection system.
The technical scheme in the invention for solving the above technical problem is: a kind of shallow embedding horizontal well method rubbish landfill gas is received
Collecting system, is laid in rubbish heap, is made up of main trachea, bend pipe, VERTICAL TUBE, branch trachea and floral tube, and main trachea is arranged on ground
Table, is connected by bend pipe and VERTICAL TUBE, and the end of branch trachea and Duo Gen floral tube connect, and main trachea is provided with air valve, and it is special
Levy and be: described rubbish surface covers HDPE film, digs anchoring groove respectively on four limits of film, then four limits of film are put in ditch again
It is backfilling and compacted with rubbish or dregs；The described rubbish heap heap buried degree of depth is more than 3 meters, and branch trachea and collecting pipe are embedded in HDPE film
0.3 to the 1 meter of degree of depth in lower section, level is laid.
It is provided with main valve on described main trachea, connects after main valve and have gas equipment for reclaiming, gas equipment for reclaiming to include burning
Stove, jet dynamic control, collecting methane equipment.
The described anchoring groove degree of depth is more than 1 meter, and collecting pipe spacing is 20 meters.
This utility model is that the gas escape status analysis stacking environment and generation for rubbish is researched and developed after improving,
According to gas distribution in waste layer, avoid rubbish landfill gas to escape by overlay film, formed and store gas-bearing formation, and properly
Height collect rubbish landfill gas.
Compared with prior art, the utility model has the advantage of: its construction cost is lower, it is not necessary to lay multilayer pipe
Road, pipeline depth is relatively low, and pipeline is hardly damaged, it is easy to safeguard.The rubbish landfill gas produced is suppressed by it by the method for overlay film
Below HDPE film, HDPE film forms an arch by anchoring groove structure and stores gas-bearing formation, and rubbish landfill gas data feedback channel is by HDPE
Film is stopped, and is storing gas-bearing formation accumulation, is being difficult to diffusion, and the degree of depth of collection is arranged on HDPE, the degree of depth of about 0.5 meter below film, tool
Having higher gas collecting rate, through experimental test, collection and confinement of gases rate can reach 60-70%, and collection and confinement of gases efficiency is high.
And compared to vertical shaft method, the rubbish landfill gas collection system of shallow embedding horizontal well method, construction intensity is low, can be at rubbish heap
The long-pending later stage can be carried out at any time, the problem decreasing and laying deep-well.
Accompanying drawing explanation
The schematic diagram of rubbish vertical shaft method in Fig. 1, prior art.
Fig. 2, plane figure schematic diagram of the present utility model (top view).
Fig. 3, elevation of the present utility model (elevation).
Wherein 1 is main trachea, and 2 is air valve, and 3 is bend pipe, and 4 is VERTICAL TUBE, and 5 is branch trachea, and 6 is collecting pipe (floral tube), 7
For extension, 8 is main valve, and 9 is gas equipment for reclaiming, and 10 is anchoring groove, and 11 is backfill layer, and 12 is HDPE film, and 13 is waste layer,
14 is ground.
Detailed description of the invention
Below in conjunction with the accompanying drawings the embodiment of utility model is further described.
A kind of shallow embedding horizontal well method rubbish landfill gas collection system, for the dumping point of the degree of depth more than 3 meters.
Its specific practice as shown in Figures 2 and 3, carries out rubbish surface at place where the garage is piled up and covers the HDPE of one layer of 1.0 thickness
Film, digs 1 meter to 2 meters deep anchoring groove 10 respectively, then four limits of film is put in ditch again by dregs backfill pressure on four limits of film
Real, the thickness about about 0.5 meter of backfill layer 11.Lower 0.5 meter (degree of depth D in figure) place of HDPE film buries collection and confinement of gases pipeline, gas underground
Collection conduit is branch trachea 5 and collecting pipe, in fork type be distributed, branch trachea 5 be a bore be 160 pipelines, level spread
If stretch out the collecting pipe (floral tube) of one 90 on branch trachea respectively to both sides every 20 meters.
Being welded with bend pipe 3 in the front end of branch trachea, film is worn out welded seal the most again, the pipeline worn out welds curved again
First, exposed portion, ground is incorporated on the main trachea of collection system after air valve.According to refuse landfill place size,
Appropriate number of branch trachea and collecting pipe are set.
It is provided with main valve 8 on main trachea, near main valve, is provided with air gauge.After rubbish has been backfilling and compacted, gaseous fermentation 6
Individual month to 1 year, detected air pressure on main trachea, after air pressure reaches convenient pressure, gas equipment for reclaiming of plugging on main trachea,
Gas equipment for reclaiming includes incinerator, collecting methane equipment or fuel gas generation equipment, is carried out back by the rubbish landfill gas of generation
With.
Using the rubbish landfill gas collection system of shallow embedding horizontal well method compared to original vertical shaft method garbage collection system, it is executed
Work amount is less, can carry out at any time in the later stage of sanitary fill, the problem decreasing and laying deep-well, be greatly saved construction
With management cost.
And, compared to original vertical shaft method garbage collection system, it have employed overlay film and the method digging anchoring groove location,
When rubbish landfill gas upwards volatilizees along the gap in rubbish, HDPE film becomes the huge rubbish landfill gas of about 1 meter
Bubble, and pressed by the backfill layer 11 of above compacting, internal rubbish landfill gas will not be escaped.Therefore aerogenesis body is received
Collection rate is higher, decreases the slow escape of rubbish landfill gas, is conducive to protecting environment.
