Abstract
The utility model discloses a vertical bleed gas well for a refuse landfill. The vertical bleed gas well comprises a suction pipe, a flow control valve, a middle connecting tube and a perforated pipe sequentially connected as well as a clay layer, a bentonite layer, a seal ring, geotechnical cloth and a gravel layer sequentially arranged from top to bottom. The penetrated pipe is arranged in the gravel layer, and a monitoring port and a temperature sensor are arranged on both sides of the suction pipe. The vertical bleed gas well disclosed by the utility model can effectively extract landfill gas in landfill and has the characteristics of good sealing structure of the bleed gas well, convenience in operation and maintenance and capability of controlling the gas flow.
Description
Technical field
The utility model relates to the landfill-gas collecting technology of refuse landfill, is specifically related to a kind of refuse landfill vertical extraction well.
Background technology
Along with rapid economic development in recent years, the people's standard of living also improves constantly thereupon, Domestic Refuse rapidly increases, it is the processing mode the most generally adopted at present that domestic refuse is processed in sanitary landfill, domestic refuse, after sanitary landfill, can produce and take methane and the carbonic acid gas landfill gas as major ingredient.If do not carry out suitable collection emission treatment, landfill gas knows from experience accumulation in landfill yard, to external leakage, diffusion or move in soil, easily causes the junk-heap body avalanche and to surrounding environment with human health works the mischief and detrimentally affect.When methane reaches finite concentration, can set off an explosion and fire; Also may cause that ground water hardness raises; Methane in landfill gas can cause scarce the supporting of landfill yard and surrounding plants Yin Gen district and dead and aggravation global warming to airborne release and diffusion; Trace toxic gas in landfill gas causes damage etc. to the mankind's major organs.Therefore need to use extraction well to extract the landfill gas in garbage loading embeading, and the landfill gas of collecting can be used as the utilization of resources.
The utility model content
The purpose of this utility model is to provide a kind of refuse landfill vertical extraction well, can effectively extract the landfill gas in garbage loading embeading, has that the extraction well sealed structure is good, convenient operating maintenance, and can control the characteristics of gas flow.
The purpose of this utility model is achieved through the following technical solutions: a kind of refuse landfill vertical extraction well, comprise the extraction pipe, flowrate control valve, intermediate connection tube and the perforated pipe that connect successively, and the clay from top to bottom set gradually, bentonite bed, sealing-ring, geotextile and gravel bed; Described perforated pipe is placed in gravel bed; The both sides of described extraction pipe are provided with monitoring mouth and temperature sensor.
The sidewall of described extraction pipe is provided with tensimeter.
Further, described intermediate connection tube is wrapped in clay, bentonite bed and gravel bed.
Principle of work of the present utility model: it is the processing mode the most generally adopted at present that domestic refuse is processed in sanitary landfill, and domestic refuse, after sanitary landfill, can produce and take methane and the carbonic acid gas landfill gas as major ingredient.The vertical extraction well is for the refuse landfill of having bound or the landfill zone of having completed, and also can be used for still at the landfill yard of operation, landfill gas being extracted out, and the landfill gas of collection can be used as the utilization of resources.In rubbish body after landfill, pierce the approximately cavity of 900～1000mm, aperture, from the pipe end, apart from landfill surface 3～4m, perforated pipe is set, placed around gravel bed at perforated pipe, intermediate connection tube is between extraction pipe and perforated pipe, intermediate connection tube is wrapped in clay, in bentonite bed and gravel bed, the clay from top to bottom set gradually, bentonite bed, sealing-ring, geotextile and gravel bed, the both sides of extraction pipe are provided with monitoring mouth and temperature sensor, be convenient to monitor the parameters such as landfill gas concentration, flowrate control valve is controlled the rate of air sucked in required size, the sidewall of extraction pipe is provided with tensimeter, tensimeter is for extraction pipe pressure in observation tube.
In sum, the beneficial effects of the utility model are: the utility model vertical extraction well can effectively extract the landfill gas in garbage loading embeading, adopt the clay, bentonite bed, the sealing-ring that set gradually from top to bottom, has multi-sealing structure, make the extraction well stopping property better, the instrument convenient operation maintenances such as the tensimeter of installing, monitoring mouth, temperature sensor, flowrate control valve is for controlling gas flow.
