Embodiment Construction

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0034] Existing landfills generally have insufficient management of landfill gas (LFG) generated by the degradation of organic waste in landfills. In contact with the air, it is possible to cause a fire or even explode and destroy the entire landfill. In order to avoid the above-mentioned risks, some more developed areas will install collection devices inside the landfills of waste landfills to collect landfill gas, and then incinerate them after concentration. However, this kind of resource waste and polluti...

Abstract

The present invention relates to a garbage landfill gas treatment method and a garbage landfill gas treatment system, wherein the garbage landfill gas treatment method comprises collection, compression, cooling, hydrogen sulfide removal, cryogenic separation, carbon dioxide removal, nitrogen injection, odorant adding, and other steps. With the method and the system of the present invention, the garbage landfill gas is purified and converted into synthetic natural gas, and the synthetic natural gas can directly enter domestic fuel gas pipelines so as to reduce the fossil fuel consumption, such that the emissions (such as carbon dioxide) of greenhouse gases are reduced while the pollution of burning of the garbage landfill gas on the environment is avoided.

Description

technical field [0001] The invention relates to the field of landfill technology, and more specifically, to a method and system for treating landfill gas. Background technique [0002] Landfill gas (LFG), which contains methane and carbon dioxide, is produced by the degradation of organic waste in landfills. Since the landfill gas will migrate from the surface and underground of the landfill to the surrounding area, methane gas that is flammable, explosive and has a high combustion value poses a potential hazard to the vicinity of the landfill. Landfill gas must be collected and disposed of due to the potential hazards of this migration. However, the existing landfills mainly use combustion to deal with landfill gas. Not only does a large number of infrastructure facilities for collecting and burning landfill gas not bring any economic benefits, but also the waste gas generated by combustion will pollute Surroundings. Contents of the invention [0003] The technical pro...
