Air cushion-type under-film landfill deodorizing structure

Abstract

The invention provides an air cushion-type under-film landfill deodorizing structure. The air cushion-type under-film landfill deodorizing structure comprises a supporting structure and a deodorizingdevice, wherein the supporting structure is an inflatable cushion with load-bearing capacity; the supporting structure is placed on the working surface of a garbage dump on the same day, and when a garbage covering film covers garbage, the supporting structure is completely covered and a certain margin is left; an inflating device can inflate or deflate the inflatable cushion to expand or shrink the inflatable cushion; in an inflated state of the inflatable cushion, the garbage covering film is lifted up; in the inflated state of the inflatable cushion, the deodorizing device can spray a deodorizing agent under the film according to a control condition. Before film uncovering, the deodorizing device and the inflating device are closed first, so that the film uncovering operation is not affected; and the deodorizing agent is sprayed under the film, the concentration of odor during film uncovering is greatly reduced, so that the discharge concentration of the landfill odor can be greatlyreduced during the film uncovering operation. The air cushion-type under-film landfill deodorizing structure is simple, and can be newly arranged in the existing landfill without the need of pre-planning arrangement before landfill construction.

Description

technical field [0001] The invention relates to the technical field of deodorization devices, in particular to an under-membrane deodorization structure of an air cushion type garbage landfill. Background technique [0002] There is a large amount of garbage accumulated in the landfill, and the odor of the garbage is produced by the decomposition of bacteria in the garbage. In the process of natural digestion, under the action of aerobic / anaerobic fermentation, etc., the odor is produced, especially in the When the weather is hot, due to the acceleration of fermentation, the odor becomes more serious. Malodorous gases can cause varying degrees of poisoning to human respiratory, digestive, cardiovascular, and endocrine systems, and aromatic compounds can also cause distortion and canceration in humans. Its foul smell also causes serious adverse effects on the environment. [0003] The method of controlling malodorous gas is mainly to spray deodorant on the garbage pile of t...

AI Technical Summary

Problems solved by technology

[0004] The garbage pile in the landfill site will not receive garbage at night. Before the landfill site does not work at night, it will temporarily cover the garbage cover film to cover all the garbage in the landfill site and let the garbage ferment at night. The biogas can be collected and the temporary membrane can be removed before work the next morning, but the stench emitted by the garbage dump after the temporary membrane is removed is very huge, although a large amount of water will be sprayed on the garbage dump before the temporary membrane is covered. Deodorant and deodorant that is also sprayed on the temporary film of the garbage dump at night, but it is difficult to suppress the stench generated at night
