Embodiment Construction

[0013] As shown in the figure: on the ground 10 where the rubbish 11 is piled up, the low wall 4 built with demolished construction waste etc. surrounds the rubbish 10 circles, so that the rubbish 11 is heightened and piled up as much as possible under the premise of not adding new contradictions. The shape of a small hill can reduce the land occupation. Then set some chimney-shaped chimney pipes 18 [can be transformed from old pipes] at appropriate intervals between each mountainside——or vertically or obliquely or in a herringbone shape so that one port is raised above the garbage 11 and side sundries 1 Get final product up to 1.5 meters -- also should add cover on this port and establish the cap 17 that can prevent rubbish and rainwater but do not hinder gas from entering chimney pipe 18. The rubbish 11 that this piles up naturally can retting go out biogas and accumulatively exposes in the relatively empty space [normally higher] place of the inner volume of cover screen 12...

Abstract

The invention relates to a connected and fixed film cover-screen garbage biogas system. According to the invention, a large-area leakage-preventing cover screen is spliced by using cheap cloth-film large-area films (which can be spliced by using waste objects); a large amount of garbage surrounded by walls can be covered, and the garbage can be turned into biogas and can shrink in a sealed space, such that biogas can be produced and can be applied. The method is especially suitable to be used for digesting garbage piles in landfills produced within years with a backward method, and a simple and easy method for produce energy by using wastes is developed. Soft pressure pipes for storing water and for pressurizing is adhered and connected to the outside of periphery of the cover screen, such that the edges of the cover screen do not curl from the ground. A convex ring is provided outside, such that earth which assists in providing large uniform pressure intensity can be used for enhancing sealing and reducing pollutant leakage. 8 chimney pipes are provided in the cover screen, such that a proper space can be formed by supporting, and biogas can be produced; and biogas can be delivered outwards by using the pipes with ports at relatively high positions. A pump is communicated at the lower part of the chimney pipe, such that biogas discharging can be promoted, and gas or liquid assists in producing biogas can be sprayed in. A proper pressure intensity assisting the cover screen to resist external forces can be maintained, and high-pressure leakage can be provided. Therefore, the system is less annoying, such that a building address is easy to select. The system provided by the invention is comprehensively better and cheaper than a garbage incineration method.

Description

Technical field: [0001] The invention relates to a device for generating biogas from cheap and easy-to-digest accumulated garbage and its application method. Background technique: [0002] At present, disposing of garbage has become a major problem in the city and costs a lot. Invention content: [0003] In order to dispose of garbage cheaply and environmentally friendly, especially to deal with the mountain of garbage formed in the landfill, the present invention provides a clip-linked film-covering type garbage biogasification system. [0004] The technical measures adopted by the present invention to solve the technical problems are: on the large-scale garbage [mountain] heap, a plurality of large-area film pieces are combined to form a huge covering curtain to cover the garbage by means of multiple sets of bolt clamping strips, etc. Attached to the ground with a soft pressure tube, flushing water at the right time to seal the gap, forming a volume sealed by a soft cur...
