Specific implementation mode
The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention..
As shown in Fig. 2, the surface gas collection device include gas collection floral tube 1 under more films, wear membrane tube 2, gas is led
Comb 3 and film 4, gas collection floral tube 1 offers on the peripheral surface of gas collection floral tube 1 more in tubular construction, under film under film
A through-hole, landfill gas can be entered by through-hole under film inside gas collection floral tube 1, since the quantity of through-hole is more, even if wherein
A through-hole be blocked, landfill gas can also be entered by other through-holes beside the through-hole.Gas collection floral tube 1 is in and puts under film
It penetrates shape and is arranged in the periphery for wearing membrane tube 2, the angle under adjacent two films between gas collection floral tube 1 is identical, gas collection under film
One end of floral tube 1 is connect by multiple-pass joint with the lower end for wearing membrane tube 2.Multiple-pass joint has multiple interfaces, and multiple-pass joint is at this
Be five-way joint in embodiment, one of interface connect with the lower end for wearing membrane tube 2, remaining four interface respectively under four films
One end of gas collection floral tube 1 connects, but it's not limited to that for the quantity of multiple-pass joint interface, is received with specific reference to gas under film
The quantity for collecting floral tube 1 determines, carries out the connection between pipeline using multiple-pass joint, can facilitate and be mounted and dismounted to it.Film
Wear radially extending for membrane tube 2 in the other end edge of lower gas collection floral tube 1.The quantity of gas collection floral tube 1 is in the present embodiment under film
In be four, but it's not limited to that.The outer diameter of gas collection floral tube 1 is DN90mm under film, gas collection floral tube 1 under film
Length is 0.5-3m, preference 2m, can be by it from leading after use since the length of gas collection floral tube 1 under film is shorter
It is taken out in row's french drain 5, it is ensured that gas collection floral tube 1 can be recycled completely under film.Gas collection floral tube 1 is PVC floral tubes or PE under film
Floral tube, preference are PE floral tubes, and PE floral tubes have the advantages that intensity height, high temperature resistant and erosion-resisting.By by gas collection under film
Floral tube 1 makes a netted system, can strengthen local collecting effect, improves the rate of recovery of gas.
It wears membrane tube 2 to be vertically arranged, the upper end for wearing membrane tube 2 is connect with one end of gas discharge guiding pipe 3, wears membrane tube 2 by gas under film
Body is collected the landfill gas in floral tube 1 and is imported in gas discharge guiding pipe 3.The other end of gas discharge guiding pipe 3 connects with gas treatment equipment 7
It connecing, the internal diameter of gas discharge guiding pipe 3 is more than the internal diameter of gas collection floral tube 1 under film, when reducing gas by gas discharge guiding pipe 3
Resistance, the landfill gas being collected into are led by gas discharge guiding pipe 3 and are delivered to gas treatment equipment 7.
Film 4 offers installing port, and film 4, which is sheathed on, to be worn in membrane tube 2, and film 4 and the peripheral surface welding for wearing membrane tube 2 connect
It connects, but it's not limited to that for the connection type of the two, and pressure ring or gluing connection also can be used.Film 4 is PE films, and film 4 covers
It is placed on landfill yard surface, prevents landfill gas from overflowing, forces landfill gas that can only enter by through-hole under film in gas collection floral tube 1
Portion.
As shown in Figure 1, in use, an aqueous vapor guide is arranged between surface gas collection device and each collection gas well 6
French drain 5,5 cross dimensions of guide french drain are 1m × 1m, and the rubble that inside filling grain size is diameter 30mm-60mm will be under each film
Gas collection floral tube 1 fills in corresponding french drain, and gas collection floral tube 1 can strengthen local collecting effect under film.Due to
Gas collection floral tube 1 is in guide french drain 5 under film, does not interfere with being normally carried out for other subsequent jobs.Film 4 is covered again
In the surface of landfill yard, film 4 is welded to connect with the peripheral surface for wearing membrane tube 2, at this point, film 4 is as the same gas collection cap,
It forces landfill gas that can only enter by through-hole under film inside gas collection floral tube 1, then passes sequentially through and wear membrane tube 2 and gas discharge guiding pipe
3, it is eventually delivered to gas treatment equipment 7.
