Abstract
The utility model provides an air-lift water pumping device for landfill gas collecting wells, which comprises a water pumping pipeline and a compressed air pipeline, wherein the water pumping pipeline is provided with a water inflow gas port and a gas-water mixture outlet, the upper portion is provided with the compressed air pipeline with an air inlet, the lower portion of the compressed air pipeline is equipped with a hook portion which penetrates through the water inflow gas port on the water pumping pipeline and then stretches into the water pumping pipeline, and the hook portion is provided with an air outlet. The air-lift water pumping device for the landfill gas collecting wells has low fabrication cost, reliable use, safety and strong adaptability.
Description
Technical field:
The utility model is relevant with water plug, collects well with rubbish landfill gas especially and uses the gas lift method water plug relevant.
Background technique:
In rubbish landfill gas (biogas) resourceful utilization, all be to carry out collecting methane by being drilled with sludge gas collection well at the landfill layer, in the collecting methane process, the water level of rubbish inside is very big to the effectiveness affects of collecting methane, is an important link so reduce the landfill gas that is operated in of water level in collecting.
The water of rubbish inside mainly be form in the course of reaction ooze drop liquid, the pollutant load height, kind is many, COD concentration, ammonia nitrogen concentration and colourity are all very high, its penetrating power in rubbish inside is also very poor, because the landfill yard area is generally all bigger, a little density is arranged to such an extent that very highly just practical effect can be arranged so needs will draw water.
In early days, once attempted being drilled with pumped well specially in suitable place, and drew water with electronic sewage pump, reducing this regional water level, but the result costs a lot of money by (drilling cost) but poor effect; Attempted afterwards adding holding water pump at every mouthful of biogas well, obtained good effect, but adopt electric water pump to exist following drawback: 1, safety problem, because sludge gas collection well has been full of inflammable gas (mainly being methane), can produce great security incident in case ignited by electrical spark, general domestic in addition landfill yard personnel are mixed and disorderly, have been covered with behind the electric wire and easily cause electric shock accidents; 2, difficult wiring, large vehicle equipment comes and goes frequently in the cost height, landfill yard, and can carry out landfill operation frequently in the place, causes sizable difficulty to wiring; 3, the sludge gas collection well quantity of each landfill yard does not wait to hundreds of from tens, oozes drop liquid and causes pipeline blockage, corrosion through regular meeting, and the abominable fault that is easy to cause motor and water pump again of working environment causes maintenance workload very big in addition; 4, because it is very slow to ooze drop liquid seepage velocity in rubbish, the answer of well water position is very slow and each well speed differs, same well is also different in different period speed to cause every mouthful, such situation needs the device fluid level control device, is not too suitable but use charged fluid level controller under this rugged environment of landfill gas collection well.
The model utility content:
The purpose of this utility model is in order to overcome above deficiency, to provide a kind of cost low, use reliably, safety, the landfill well collection well gas lift method water plug that applicability is strong.
The purpose of this utility model is achieved like this:
The utility model landfill gas is collected well gas lift method water plug, include the pumping conduit of the gentle aqueous mixtures outlet of water gas port into, the compressed air line that suction port is arranged at top, there is the water inlet gas port that passes on the pumping conduit compressed air line bottom and stretches into the hook portion of the band relief opening in the pumping conduit.
Above-mentioned compressed air line lower shape is the U type.
During work, the utility model is put into collection well water, logical not compressed-air actuated the time, the water level of drinking-water pipe inside and outside are levels, after feeding pressurized air, the U type relief opening ejection of pressurized air in pipeline, produce a lot of bubbles in drinking-water pipe, make the water in the drinking-water pipe become solution-airmixture, the proportion of this solution-airmixture is less than the water of water pipe outside, externally under the effect of hydraulic pressure, the surface of gas-liquid mixture will move up, and is higher than the outside water surface, when being higher than the air-water mixture outlet of drinking-water pipe top, water is gentle just discharges from drinking-water pipe together, reaches the purpose of drawing water.Adjust compressed-air actuated suction pressure, can make that the ratio of air and water changes in gas-liquid mixture, making the density of solution-airmixture different, thereby change the height that gas-liquid mixture is lifted under the situation that externally liquid level is constant, also is that the speed of drawing water changes.
The utlity model has following advantage:
1, cost and cheap is used very reliably, and the effect that obtains is also pretty good, can adjust the speed of drawing water according to the water yield of every mouthful of biogas well and draw water incessantly in 24 hours, even the maintenance of breaking down is quite simple.
2, without any potential safety hazard, power adopts through post-decompression pressurized air, personal injury accident can not take place, owing to itself be that the material that is dirt cheap is made, the phenomenon of being stolen can not take place yet in addition.
3, applicability is strong, and its volume can be done very long and narrowly, can reach in the very thin biogas pipe and draw water, also can be as extracting methane pipeline condensed water and other sewage etc.
Description of drawings:
Fig. 1 is the utility model structural representation.
Embodiment:
Referring to Fig. 1, present embodiment 1 landfill gas is collected well gas lift method water plug, includes into that water gas port 1 and air-water mixture export 2 pumping conduit 3, and the compressed air line 6 of suction port 4 is arranged at top.The compressed air line lower knuckle becomes the hook portion 7 of its band relief opening 5 of U type to pass the water inlet gas port on the pumping conduit and stretch in the pumping conduit.Sequence number 8 is an air-water mixture among the figure.
Claims (2)
1. landfill gas is collected well gas lift method water plug, it is characterized in that including the pumping conduit of the gentle aqueous mixtures outlet of water gas port into, the compressed air line that suction port is arranged at top, there is the water inlet gas port that passes on the pumping conduit compressed air line bottom and stretches into the hook portion of the band relief opening in the pumping conduit.
2. landfill gas as claimed in claim 1 is collected well gas lift method water plug, it is characterized in that the compressed air line lower shape is the U type.
