Background technology
Landfill yard for being not provided with landfill gas guide system, usually after junk-heap body rises to certain altitude, Biogas well construction landfill gas collecting system is beaten on junk-heap body.Newly-built landfill gas collecting system needs to combine landfill yard actual conditions 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.
Utility model content
For above technical problem, the utility model discloses a kind of water draw-off of rubbish landfill gas collection system, this Water draw-off need not set cold trap to realize draining in addition, and easy for installation.
On the other hand, the technical solution adopted in the utility model is:
A kind of water draw-off of rubbish landfill gas collection system, it includes gas collecting main pipe, reducing tee and drainage pipeline, institute The bottommost and middle part for stating gas collecting main pipe are provided with multiple reducing tees, and the reducing tee is connected with drainage pipeline;The gas collection Side slope of the supervisor along garbage loading embeading heap body is laid, and the garbage loading embeading heap body includes landfill yard job platform, and the landfill yard is made Industry 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 further improvement of the utility model, the reducing tee is connected by elbow with drainage pipeline.
As further improvement of the utility model, the elbow is 90 ° of elbows.
As further improvement of the utility model, the drainage pipeline is provided with stop valve.
As further improvement of the utility model, two stop valves are interval with the drainage pipeline.
As further improvement of the utility model, the spacing between described two stop valves is 2 ~ 3m.
As further improvement of the utility model, vertically a reducing three is provided with every 4 ~ 6m on the gas collecting main pipe It is logical.
As further improvement of the utility model, vertically a reducing tee is provided with every 5m on the gas collecting main pipe.
As further improvement of the utility model, 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, the beneficial effects of the utility model are:
Using the technical solution of the utility model, when landfill yard does not have condition setting condensate liquid to collect well, can pass through The condensate liquid draining that this water draw-off realizes landfill-gas collecting pipeline is installed.Meanwhile the present apparatus can be according to the laying of collecting pipe Flexible arrangement, when specifically used, collecting well relative to fixed condensate liquid has higher flexibility.Meanwhile this sluicing fills Put it is easy for installation, it is easy to maintenance and investment it is small, can be set according to actual conditions many places, raising landfill-gas collecting pipeline condensate liquid Drainage effect.
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
Preferably embodiment of the present utility model 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.
As shown in Fig. 2 collecting pipe 1 is laid to reservoir area edge by landfill operation platform along junk-heap body side slope, the gradient with Side slope is unanimously 1:2, discrepancy in elevation 15m.Vertical height sets a set of water draw-off every 5m, is provided with 3 sets of water draw-offs altogether. Often set water draw-off is drawn by reducing tee 2, is filled after threeway by 90 ° of elbows 3 and draining, condensed water is exported to each layer rubbish Rubbish gutter.Two stop valves 5 are set on every drainage pipeline 4, to control drain operation.The water row of the drainage pipeline 4 Into gutter 6.
Above content is to combine specific preferred embodiment further detailed description of the utility model, it is impossible to Assert that specific implementation of the present utility model is confined to these explanations.For the ordinary skill of the utility model art For personnel, without departing from the concept of the premise utility, some simple deduction or replace can also be made, should all be regarded To belong to the scope of protection of the utility model.
