Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described.Obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
As illustrated in fig. 1 and 2: a kind of landfill yard landfill gas guide heat-extraction system, detection sample tap 1, appendix interface 2, cover layer 3, bentonite 4, waste layer 5, antipriming pipe 6 and filtrate Mai Tian district 7 is comprised; Described detection sample tap 1 is arranged on antipriming pipe 6 top and compact siro spinning technology; Described appendix interface 2 is arranged on and detects sample tap 1 opposite side and be communicated with antipriming pipe 6; Described antipriming pipe 6 top covers by being laid on the bentonite 4 detecting sample tap 1 top, and bentonite 4 sidewall arranges cover layer 3; Filtrate Mai Tian district 7 is set bottom described bentonite 4, and filtrate Mai Tian district 7 sidewall arranges waste layer 5.
As optimisation technique scheme of the present invention: also comprise retainer plate 8, it is inner that described retainer plate is embedded in filtrate Mai Tian district 7, and fixed by antipriming pipe 6, and placing porous pipe 6 rocks when extracting gases, makes whole service life more of a specified duration; Described retainer plate 8 is that semicircle PE material makes and is connected by screw, and described antipriming pipe 6 is cirque structure, conveniently buries the gas filling out gas interior and enters into appendix interface 2 place; Also comprise port cap 9, described port cap 9 is hat-shaped structure and is uniformly distributed suction hole above, makes gas enter into antipriming pipe 6 fast inner; Described cover layer 3, bentonite 4 and filtrate Mai Tian district 7 form T-shaped structure, and bentonite 4 is embedded in cover layer 3 inside.
