It is designed.In particular cases edge reserved space in landfill yard reservoir area is very limited some, leads to not set cold trap
To collect the condensed water in landfill gas.If will be destroyed in anchored platform design cold trap to leakage preventing structure, exist larger
Risk.It is this can not cold trap be set in the case of, it is necessary to using unconventional design, to realize landfill gas collecting system
Draining.
The content of the invention
For above technical problem, the invention discloses a kind of water draw-off of rubbish landfill gas collection system, this sluicing
Device need not set cold trap to realize draining in addition, and easy for installation.
On the other hand, the technical solution adopted by the present invention is：
A kind of water draw-off of rubbish landfill gas collection system, it includes gas collecting main pipe, reducing tee and drainage pipeline, the collection
The bottommost of gas supervisor and middle part are provided with multiple reducing tees, and the reducing tee is connected with drainage pipeline；The gas collecting main pipe
Laid along the side slope of garbage loading embeading heap body, the garbage loading embeading heap body includes landfill yard job platform, the landfill yard operation horizontal
Platform is provided with gas gathering station, and the outlet of the gas gathering station on the landfill yard job platform is connected with gas collecting main pipe.
Using this technical scheme, this water draw-off need not set cold trap in addition, can not set the bar of cold trap
The drainage requirement of landfill gas collecting system is realized under part, relative to cold trap is set, this water draw-off can be according to collecting pipe
Position flexible arrangement, settable to sentence raising drainage effect and easy for installation, investment is small more.
As a further improvement on the present invention, the reducing tee is connected by elbow with drainage pipeline.
As a further improvement on the present invention, the elbow is 90 ° of elbows.
As a further improvement on the present invention, the drainage pipeline is provided with stop valve.
As a further improvement on the present invention, two stop valves are interval with the drainage pipeline.
As a further improvement on the present invention, the spacing between described two stop valves is 2 ~ 3m.
As a further improvement on the present invention, vertically it is provided with a reducing tee every 4 ~ 6m on the gas collecting main pipe.
As a further improvement on the present invention, vertically it is provided with a reducing tee every 5m on the gas collecting main pipe.
As a further improvement on the present invention, the HDPE that the gas collecting main pipe is DN200 is managed, and the reducing tee is
DN200/DN90 HDPE reducing tees.
Compared with prior art, beneficial effects of the present invention are：
Using technical scheme, when landfill yard does not have condition setting condensate liquid to collect well, can originally be let out by installation
Water installations realize the condensate liquid draining of landfill-gas collecting pipeline.Meanwhile the present apparatus can according to the laying flexible arrangement of collecting pipe,
When specifically used, collecting well relative to fixed condensate liquid has higher flexibility.Meanwhile this water draw-off installation side
Just, easy to maintenance and investment is small, can be set according to actual conditions many places, improves the condensate liquid draining effect of landfill-gas collecting pipeline
Fruit.
Brief description of the drawings
Fig. 1 is a kind of structural representation of the water draw-off of rubbish landfill gas collection system of the embodiment of the present invention.
Fig. 2 is that the rubbish landfill gas collection conduit of the embodiment of the present invention arranges schematic diagram.
Embodiment
The preferably embodiment of the present invention is described in further detail below.
As shown in figure 1, a kind of water draw-off of rubbish landfill gas collection system, the water draw-off include：Collecting pipe 1,
2,90 ° of elbows 3 of reducing tee, stop valve 5 and drainage pipeline 4.The bottommost of the collecting pipe 1 and middle part are provided with multiple reducings
Threeway 2, the reducing tee 2 are connected by 90 ° of elbows 3 with drainage pipeline 4；The collecting pipe 1 is along garbage loading embeading heap body
Side slope is laid, and reservoir area edge is led to by job platform.The garbage loading embeading heap body includes landfill yard job platform, the landfill yard
Job platform is provided with gas gathering station, and the outlet conduit of each gas gathering station on the landfill yard job platform is collected on collecting pipe 1.
The HDPE that wherein collecting pipe 1 is DN200 is managed.Vertically every 5m height and the minimum point of collecting pipe 1 on collecting pipe 1
Place's one reducing tee 2 of welding, by discharge outlet of the low side of threeway as condensate liquid.
The collecting pipe 1 is DN200 HDPE collecting pipes 1.The HDPE that the reducing tee 2 is DN200/DN90 becomes
Footpath threeway 2.90 ° of elbows 3 are HDPE elbows, and drainage pipeline 4 is the DN90 in line water pipes of HDPE.Welded after reducing tee 2
One 90 ° of HDPE elbows, elbow draw condensate liquid, and setting angle is adjusted according to the position of actual drainage point.With row
Waterpipe 4 exports condensate liquid to drainage point.
As shown in Fig. 2 be provided with two stop valves 5 on the drainage pipeline 4, respectively the first stop valve 51 and second section
Only valve 52, stop valve 5 select PVC material, retain certain spacing between two stop valves 5, are determined with specific reference to drainage position,
Typically in 2 ~ 3m.During working condition, the first stop valve 51 is normally opened, and the second stop valve 52 completely closes, by the first cut-off during draining
Valve 51 is closed, and the second stop valve 52 opens draining.Working condition is returned to after the completion of draining.
