Rubbish under sanitary landfills mode, which is concentrated, stacks place, and garbage sanitary filling field is because at low cost be widely used at home.State
Interior maximum refuse landfill is Guangzhou Xing Feng refuse landfill, day handles about 7000 tons of house refuse or so.
Refuse landfill is generally handled rubbish by the way of layering earthing landfill, is covered after accumulating one layer of rubbish
One layer of loess, can reduce the pollution of rubbish in this way.Rubbish is slowly decomposed under the action of microorganism, but rubbish is dividing
A large amount of gas can be generated in solution preocess.Mainly by CH4, CO2, N2, O2 sulfide, NH3, H2S, CO and other minor compounds
Composition.Usual methane volumetric score is 45-60%, CO2 40-50%.
Carbon dioxide is a kind of greenhouse gases, and the greenhouse hazard ratio carbon dioxide of methane is bigger, and greenhouse effects are
21 times of quality carbon dioxide.Methane is a kind of inflammable and explosive gas, explosion limit 5%-15%, is generated in rubbish
Methane such as cannot timely be discharged, and the more will accumulate the more more, finally can be in the dual-pressure of pressure itself and junk-heap body pressure
It is lower to explode, so that junk-heap body is collapsed, or even jeopardize the security of the lives and property of landfill yard surrounding resident.So needing real-time
Monitor the concentration of methane.
And existing check device has the following problems:
(1) existing detection device can only be acquired the gas of some point, then be tested, due to garbage loading embeading
It is to be handled by the way of layering earthing landfill rubbish, velocity of liquid assets is slow between air-flow, different depth, different location
Methane concentration is inconsistent, if carrying out single-point detection, the result and inaccuracy that detected；
(2) since microorganism decomposition rubbish can generate hydrogen sulfide etc. with corrosive gas, if directly detected, detection
Instrument abrasion is accelerated；
(3) dust and moisture of refuse landfill also will affect the inspection result of detector, cause testing result inaccurate.
Utility model content
The utility model aim is intended to provide a kind of refuse landfill Pollution Gas detection device, can be from depth

Solution, the filtering container are arranged on the acquisition general pipeline, are located at after the gas flowmeter；The drying structure is also set
It sets on the acquisition general pipeline and after the filter structure, before aspiration pump.
Utility model by adopting the above technical scheme, the double-deck iron net and filter layer can prevent the impurity such as soil, rubbish into
The inside blocking acquisition branch pipe of the collection tube entered；The acquisition branch pipe that is vertically arranged and along acquisition branch pipe length direction setting
Acquisition port, the gas of different height can be acquired by the opening and closing of the first solenoid valve of control, obtain the inspection knot of the height
Fruit can also acquire the gas from different acquisition branch pipe by the opening and closing of control second solenoid valve, obtain the inspection of methane
As a result, methane concentration distribution map may finally be obtained, the true concentration for reacting methane；The acquisition port of trumpet type can expand
The contact area of acquisition port and gas to be collected improves the accuracy of testing result；Corrosive gas filter structure can remove
Hydrogen sulfide corrosion gas extends the service life of aspiration pump, detector；Drying structure can effectively go out moisture to detection knot
The influence of fruit further increases the accuracy of testing result.
It further limits, the filter layer is that goose warms up stone.
It further limits, the depth in the acquisition hole is greater than or equal to the depth of garbage loading embeading.
It further limits, the solution is copper-bath.Copper sulphate can react production deposit with hydrogen sulfide.
It further limits, drying structure includes drying receptacle, and the drying receptacle is provided with the first filter screen, is held dry
It is divide into upper part and lower part inside device, is above filled partially with desiccant, the lower part of drying receptacle is separately equipped with drainage hole.
Detailed description of the invention
The utility model can be further illustrated by the nonlimiting examples that attached drawing provides；
Fig. 1 is the structural schematic diagram of the utility model；
Main element symbol description is as follows:
