Description
Technical field
The utility model belongs to rubbish landfill gas collection technique field, and in particular to a kind of rubbish landfill gas collection well.
Background technique
China is that the highest country of municipal refuse yield, rubbish pollute soil, atmosphere, water body in the world, both shadow
The ecological environment of people has been rung, and has jeopardized the living environment of people.Garbage loading embeading biogas (LFG) is the degradation of sanitary filling field
One of product removes main component CH4, and outside C02, other substances being detected have 140 kinds or more.These gases are uncontrolled
Migration and accumulation, can generate secondary pollution, cause combustion explosion accident, garbage loading embeading biogas is a kind of greenhouse gases again, it is right
Atmospheric ozone layer has a destruction, and data shows 20 times of C02 high of greenhouse effects that garbage loading embeading biogas generates than equivalent volume
More than.
The collection system of garbage loading embeading biogas is made of export well, collection gas holder, gas pipeline and gathering station etc..Biogas relies on
Pressure difference flows to specific gas export well, then reaches collection gas holder through gas-collecting pipe, and final concentrate is delivered to gas collection station
Carry out purified treatment.Existing export well, collection efficiency is not high and there is asking for rubbish blocking horizontal well stomata in use
Topic, making horizontal well, gas collection performance is gradually reduced or even cannot use in use.
Utility model content
The utility model solves the deficiencies in the prior art, provides a kind of including collecting chamber, pit shaft and protection filter screen
Rubbish landfill gas collects well, and structure is simple, and collection efficiency is high, long service life.
The technical scheme adopted by the utility model is a kind of rubbish landfill gas collects well, including collecting chamber, pit shaft, institute
It states collecting chamber and is tubular type structure and is removably attachable on pit shaft that lateral surface is evenly arranged with air hole, the receipts
Collection outside is arranged with protection filter screen, and the end of the pit shaft is provided with sealing cover, is equipped with drainpipe on the sealing cover,
Described drainpipe one end is protruded into collecting chamber, and the other end is connected with sewage pump, and the pit shaft side perforation is circumscribed with exhaust tube,
The collecting chamber bottom is additionally provided with liquid level sensor.
Preferably, the pit shaft is made of high density polyvinyl-chloride material.
It is furthermore preferred that the collecting chamber is made of titanium alloy material, the protection filter screen is made of stainless steel.
Even more preferably, the diameter of the pit shaft is 100-300mm.
Even more preferably, the drainpipe is 100-350mm with a distance from collecting chamber bottom.
Compared to the prior art, the utility model has the advantages that a kind of rubbish landfill gas collects well, outside collecting chamber
Side is evenly arranged with air hole, and the collecting chamber lateral area is bigger than general monomer-type vertical shaft, and the air hole that can be set is more, mentions
The high efficiency for collecting gas；The collecting chamber is tubular type structure and to be removably attachable on pit shaft, and collecting chamber can be with
It reuses and easy for assemble or unload；The collecting chamber outer sheath is equipped with protection filter screen, avoids in use that there are rubbish
The problem of blocking air hole, so as to avoid well is collected, gas collection performance is gradually reduced or even cannot use in use.
Detailed description of the invention
Fig. 1 is the utility model structure diagram.
Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and detailed description.
A kind of rubbish landfill gas collection well, refering to fig. 1, including collecting chamber 1, pit shaft 2, the collecting chamber 1 are tubular type knot
It structure and is removably attachable on pit shaft 2, collecting chamber 2 can reuse easy for assemble or unload, and lateral surface is uniformly arranged
There is air hole, the collecting chamber lateral area is bigger than general monomer-type vertical shaft, and the air hole that can be set is more, improves collection gas
Efficiency, 1 outer sheath of collecting chamber be equipped with protection filter screen 3, avoid in use there are problems that rubbish block air hole,
So as to avoid well is collected, gas collection performance is gradually reduced or even cannot use in use, the end setting of the pit shaft 2
Have sealing cover 4, drainpipe 5 be equipped on the sealing cover 4, described 5 one end of drainpipe is protruded into collecting chamber 1, the other end with
Sewage pump 6 is connected, and 2 side of the pit shaft perforation is circumscribed with exhaust tube 7, and 1 bottom of collecting chamber is additionally provided with liquid level sensor
8, it is drained for detecting in collecting chamber 1 liquid level variation to control sewage pump 6.
With continued reference to Fig. 1, the pit shaft 2 is made of high density polyvinyl-chloride material, corrosion-resistant, long service life.
With continued reference to Fig. 1, the collecting chamber 1 is made of titanium alloy material, the service life that can be used in a corrosive environment
It is long, and can reuse, the protection filter screen 3 is made of stainless steel.
With continued reference to Fig. 1, the diameter of the pit shaft 2 is 200mm.
With continued reference to Fig. 1, the drainpipe 5 is 300mm with a distance from 1 bottom of collecting chamber.
In use, collecting chamber 1, pit shaft 2 are assembled together first, it is then placed in the garbage loading embeading hole dug, installation
Good sealing cover 4, drainpipe 5, sewage pump 6 and exhaust tube 7 open sewage pump 6 and sewage are discharged, and are used to detect receipts by sensor 8
Liquid level variation is drained in collection room 1 to control sewage pump 6, then collects gas by exhaust tube 7.
Above-described embodiment, the only preferred embodiment of the utility model not are used to limit the implementation model of the utility model
It encloses, therefore all equivalent variationss done with content described in the utility model claims, the utility model right should all be included in and wanted
Within the scope of asking.
