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 directly discharges the landfill gas produced by the landfill into the air. This method not only causes serious pollution and danger, but also is a serious waste of resources.
At present, there is no complete set of equipment that can monitor and comprehensively utilize the landfill gas generated by the landfill

Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0022] Such as image 3 shown.

[0023] A complete set of equipment for comprehensive utilization of landfill gas resources, connected to the gas collection well of the landfill, used for the treatment and recycling of landfill gas generated by the landfill, including a primary unit and a secondary unit, the primary unit Connected to the secondary unit via air duct. The primary unit includes screen-type gas filter 1, gas-liquid separator 2 (common baffle-type separator can be used), flow meter 3 (corrosion-resistant rotameter can be used), gas analyzer 4 (model can be used For: IST-S), fan 5 (commonly used Roots blower can be used), fan 5 can use a frequency converter to adjust the flow, and the flow meter 3 should use a flow meter that can adjust the flow. The secondary unit is made up of non-polluting combustion discharge device 6 and recycling dev...

Abstract

The comprehensive system for utilizing the gas resource of garbage landfill is connected to the gas collecting well of garbage landfill to treat and utilize the landfill gas. It includes one primary unit and one secondary unit connected to the primary unit and features the primary unit comprising screen type gas filter, gas-liquid separator, flow meter, gas analyzer and fan; and the secondary unit comprising pollution-less burning exhaust device and / or recovering utilization device. The present invention solves the problem of re-using the landfill gas resource and is favorable to environment protection.

Description

technical field [0001] The invention relates to a garbage landfill gas processing device, in particular to a complete set of garbage landfill gas resource comprehensive utilization equipment. Background technique [0002] At present, with the continuous development of urbanization, urban garbage disposal has become an important part of environmental protection. The recycling and utilization of garbage is currently the focus of research in various countries in 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...
