Gas distribution station and system for ecological restoration of household garbage landfill and adjusting method of gas distribution station

Abstract

The invention provides a gas distribution station and system for ecological restoration of a household garbage landfill and an adjusting method of the gas distribution station. According to the gas distribution station and system for ecological restoration of the household garbage landfill and the adjusting method, a single primary pipeline and a plurality of secondary pipelines are adopted, an injection-extraction integrated pipeline design in which a gas distribution tank is in butt joint is adopted in the middle, the type is scientific, the structure is reasonable, the functions are diversified, the gas injection and gas extraction functions of the whole or local field area can be achieved, through a designed explosion-proof pressure release valve, the gas amount and the gas pressure during gas injection can be safely and effectively adjusted so as to adapt to refuse landfills with different compactness, meanwhile, pipe explosion caused by too large pipeline pressure is prevented, and the gas injection operation efficiency and the safety coefficient can be improved; the negative pressure of a pile body during gas extraction can be effectively reduced, the introduction of leachate is reduced or avoided during gas extraction, and the landfill gas extraction efficiency and safety are improved; and a small amount of percolate which is possibly sucked in can be smoothly discharged through an arranged emptying pipe, so that the service life and the safe operation of equipment are not influenced.

Description

technical field [0001] The invention relates to the technical field of domestic waste landfill degradation treatment engineering, in particular to a gas distribution station, system and adjustment method for ecological restoration of domestic waste landfill. Background technique [0002] The degradation treatment of domestic waste landfills refers to the activities of accelerating the decomposition of waste components in landfills through physical, chemical, and biological methods, and realizing the stabilization of waste dumps. The aerobic rapid and stable ecological restoration process is to rapidly degrade the biodegradable organic matter in the pile through the activities of aerobic microorganisms, so as to reduce or stop the biochemical reaction activity inside the pile, reduce environmental pollution and realize the development and utilization of the site. Purpose. This process has obvious advantages such as quick effect, good effect, and no pollution. It has been ado...

Problems solved by technology

This deodorization method requires frequent preparation and filling of agents, cumbersome operation and high operating costs

[0006] In the process of daily gas injection and pumping, sometimes the air flow in the gas pipeline is blocked or there is no air flow. Blockage, corrosion of pipe valves, damage and failure to open, etc., and it is difficult to directly determine the cause. It is often necessary to check one by one after cutting or disassembling, which brings great blindness to the maintenance work, which is time-consuming, laborious and inefficient.
