Description
Technical field
The present invention relates to a kind of refuse disposal installation, the method and the system thereof of gas collection vertical shaft discharged in the draining in especially a kind of rubbish landfill gas collecting shaft.
Background technique
Rubbish in the refuse landfill can produce a large amount of landfill gas through anaerobic digestion, and (rubbish per ton can produce 100-200m
3Landfill gas), landfill gas is a kind of energy (methane content height) of recyclable utilization, is again pollution gas (methane wherein is to cause greenhouse gas by force, also contains to have irritating sulfide gas etc.) simultaneously.Therefore, the comprehensive utilization rubbish landfill gas becomes turns waste into wealth it, obtains the inevitable approach of good economic and social benefit.Setting up the vertical shaft extract system in landfill yard is a kind of main mode that at present domestic and international rubbish landfill gas is collected.
Can produce a large amount of percolates in the rubbish anaerobic digestion process, the surface runoff that produces by processes such as precipitation also can partly permeate the ground simultaneously, so the level of ground water of refuse landfill is generally higher, collects the vertical shaft of setting up in the landfill gas process and tend to owing to ponding influences the landfill gas collection rate even becomes disused well.Become a key issue on the engineering so how to discharge ponding in the vertical shaft.Domestic drainage system commonly used adopts to be installed jet pump or at silo bottom submersible pump etc. is installed and is drawn water, but effect is all not ideal, and to realize that these methods will inevitably put a large amount of electric wires at the refuse landfill middle berth, this has also brought the Electrical Safety potential problem.
Summary of the invention
The purpose of this invention is to provide a kind of novel employing pressurized air and carry out method and the system thereof that air-blowing realizes refuse landfill drainage by shaft wells purpose.
Technological scheme of the present invention is:
A kind of rubbish landfill gas is perpendicular to bury de-water, it is characterized in that utilizing pressurized air as power, and pressurized air is sent in the waste pipe that stretches in the gas collection vertical shaft, utilizes compressed air that the water in the gas collection vertical shaft is discharged outside the gas collection vertical shaft by waste pipe.
A kind of draining of vertical shaft with garbage filling gas system, comprise the gas collection vertical shaft 1 that is embedded in the rubbish heap, sealing cover 2 is installed on the well head of gas collection vertical shaft 1, the lower end of waste pipe 3 is passed sealing cover 2 and is stretched in the gas collection vertical shaft 1, the upper end of waste pipe 3 is a water outlet, exhaust tube 4 communicates with gas collection vertical shaft 1, it is characterized in that an end of compressed air hose 5 links to each other with compressed air outlet port, and the other end passes the sealing cover 2 on gas collection vertical shaft 1 well head and stretches into waste pipe 3 from the end that waste pipe 3 is arranged in gas collection vertical shaft 1.
The pressure gauge 7 of ball valve 6 and/or band modulating valve is installed at described compressed air hose 5.
The distance of an end from the shaft bottom of gas collection vertical shaft 1 that waste pipe 3 stretches into gas collection vertical shaft 1 is 0.5～1.5 meter.
The length that compressed air hose 5 stretches in the waste pipe 3 is 100～300 millimeters.
Compressed-air actuated working pressure is 0.8～1.5 * 10
6KPa.
Beneficial effect of the present invention:
Method, simple in structure, drainage effect is good, need not electric wire is introduced landfill yard, safe and reliable, has eliminated the potential safety hazard in the operation.

Embodiment
The present invention is further illustrated below in conjunction with drawings and Examples.
As shown in Figure 1, 2, 3.
A kind of draining of vertical shaft with garbage filling gas system, comprise the gas collection vertical shaft 1 that is embedded in the rubbish heap, sealing cover 2 is installed on the well head of gas collection vertical shaft 1, sealing cover can adopt Fig. 2, flange arrangement shown in 3, the lower end of waste pipe 3 is passed sealing cover 2 and is stretched in the gas collection vertical shaft 1, the distance of its lower end from the shaft bottom of gas collection vertical shaft 1 is 0.5～1.5 meter, the upper end of waste pipe 3 is a water outlet, exhaust tube 4 and gas collection vertical shaft 1 are positioned at the face of land and communicate (as shown in Figure 1) with the sidewall of bottom, one end and the compressed air outlet port of compressed air hose 5 (can be the air outlet of compressor, also can be the gas station, the air outlet of gas tank, compressed-air actuated working pressure can be 0.8～1.5 * 10
6KPa) link to each other, the other end passes the sealing cover 2 on gas collection vertical shaft 1 well head and stretches into 3 100～300 millimeters in waste pipe from the end that waste pipe 3 is arranged in gas collection vertical shaft 1.On compressed air hose 5 is positioned at pipeline section more than the face of land, ball valve 6 (as Fig. 2) can be installed, but the also pressure gauge 7 (as shown in Figure 3) of mounting strap modulating valve, the compressed air hose 5 that links to each other with compressor house and the band modulating valve pressure gauge 7 between, and the band modulating valve pressure gauge 7 with stretch into gas collection vertical shaft 1 among compressed air hose 5 between all can be connected by conventional rapid pipe joint 8.
Fig. 1 is the whole sectional drawing of drainage by shaft wells of the present invention system, Fig. 2 is the vertical shaft well head structural drawing that the drainage system of configuration ball valve 6 has been installed, Fig. 3 is the vertical shaft well head structural drawing that the drainage system of the pressure gauge 7 that disposes the band modulating valve has been installed, and is convenient to directly regulate compressed-air actuated working pressure at gas collection vertical shaft 1 place.As shown in Figure 1 from the gas collection 1 well top flange pvc pipe that to insert a diameter be DN50 as waste pipe 3 and diameter high-voltage tube that is 10mm as compressed air hose 5, the about 1m in the bottom of waste pipe 3 to gas collection vertical shaft 1 bottom, compressed air hose 3 is stretched into pvc pipe bottom 100～300mm (the best 150-200mm of being) to be located, the outlet of waste pipe 3 is connected to the leachate collection device, the import of compressed air hose 5 is connected to the air compressor in the factory building, and the arm of imbedding below the face of land on gas collection vertical shaft 1 next door is a landfill gas exhaust tube 4.
Gas collection vertical shaft 1 commonly used is all bled by exhaust tube 4 at the ground proximity place, with the related extraction of ponding in the vertical shaft, influences the collection of landfill gas in the time of will causing bleeding as if the vertical shaft middle water level is too high.When the present invention carries out draining, open air compressor, gas collection vertical shaft 1 is carried out air-blowing, the pressurized air that blasts forms air-water mixture with percolate and moves upward in waste pipe 3, until discharging gas collection vertical shaft 1.Facts have proved, when compressed-air actuated working pressure during at 0.8～1.5 kilogram, can be controlled at the water level in the gas collection vertical shaft 1 relative ground-10m～-8m between, thereby guarantee normally bleeding of gas collection vertical shaft 1.
