Problems solved by technology

In some large landfills, the content of methane in the landfill gas produced can be as high as 60%, and the main component of methane natural gas is a recyclable resource. At the same time, if methane is not comprehensively utilized, it is a A source of pollution and a dangerous gas that can produce explosions under certain conditions. If it is discharged directly into the air, it is also a gas that can cause a strong greenhouse effect. The method of collecting gas wells up to tens of meters is to regularly discharge the landfill gas produced by the landfill into the air or directly ignite it at the head of the gas collecting well, which not only cannot determine when it should be discharged, but also cannot determine whether it has regeneration Leverage value and operate entirely by experience or feeling
It not only pollutes the environment seriously, but also is dangerous, and it is a serious waste of resources

Abstract

The present invention discloses landfill gas test and torch apparatus, and the apparatus is connected to the gas collecting well to extract, measure, burn and exhaust landfill gas and consists of landfill gas test unit and pollution-less burning and exhausting unit. The present invention features that the landfill gas test unit includes screen type gas filter, gas separator, flow meter, gas analyzer and blower connected together; and that the outlet of the blower is connected with flame arrester in the pollution-less burning and exhausting unit or other subsequent post-treating and utilizing unit, with the flame arrester being connected with evacuating pipe, torch burner and igniter successively.

Description

technical field [0001] The invention relates to a landfill gas extraction, monitoring and safety discharge device, in particular to a landfill gas testing and flare device. Background technique [0002] At present, with the continuous development of urbanization, urban garbage disposal has become an important part of environmental protection. Garbage recycling is currently the focus of research in countries all over the world. Garbage sorting is a relatively good method. It is not only beneficial to environmental protection, but also Resources are saved, but there is currently no effective utilization method for some huge quantities of garbage with no use value, such as household garbage. The best way to deal with waste of no use value is to carry out centralized landfilling by setting up landfills. For this reason, every city has many landfills in the suburbs for the landfilling of garbage. The organic matter in the garbage piled in the landfill will decompose by itself in...
