Abstract

The utility model discloses a shaft is collected to landfill gas, the circular binocular hollow structure type shaft that the shaft frame was made by steel, the shaft skin and inlayer comprise the wire netting, bury full cobble between the ectonexine, can let during rubbish landfill in-process produced gas and filtration liquid enter into the shaft, blast pipe and water discharge pipe in the rethread shaft discharge, because the utility model discloses a standardized module is made to steel and wire netting etc. have certain resistance to deformation and compressive capacity, the stability of very big improvement shaft has improved the life of shaft.

Description

Vertical shaft is collected to landfill gas

Technical Field

The utility model belongs to the technical field of landfill gas is collected, in particular to landfill gas collects shaft.

Background

Along with the improvement of the living standard of people in China, the quantity of generated garbage is more and more, according to 2016 statistics, the quantity of generated garbage in China is 2.04 hundred million tons, and garbage disposal becomes one of troublesome problems. Although incineration has become a mainstream disposal method of garbage in recent years, a large amount of garbage is treated in a garbage landfill, and the number of the garbage landfills in 2016 is 657 in China. In the process of landfill, a large amount of gas, called landfill gas, is generated, and the main components of the landfill gas are methane, ammonia gas, carbon dioxide and the like. The landfill gas is a clean and renewable energy source, is successfully collected and can be used as an alternative fuel after being purified and refined.

Disclosure of Invention

An object of the utility model is to provide a well is collected to landfill gas, it is standardized to make the module with the well, can directly be applied to the landfill yard, the well after the module is standardized is difficult for the inflation, the stability of the well of very big improvement.

In order to achieve the above object, the present invention provides the following solutions:

(1) the shaft frame is a circular double-cylinder hollow structure type shaft made of steel, and the outer layer and the inner layer of the shaft are formed by wire meshes;

(2) the filter material layer consists of pebbles with different sizes, and the pebble filter material is filled between the outer layer and the inner layer of the vertical shaft;

(3) the gas collecting pipe is arranged on the cover plate at the uppermost end of the vertical shaft;

(4) and the drain pipe is connected to the lowest end of the vertical shaft.

As further priority, the wire netting of the utility model has a grid specification of 1-2 cmm.

As a further priority, the pebble of the utility model has the specification of 2cm-5 cm.

As a further priority, the gas collecting pipe of the present invention is used for collecting gas generated in the shaft.

As further preferred, the delivery pipe be arranged in collecting the filtration liquid and the solid impurity that produce in the shaft.

As further priority, shaft steel frame and wire netting, cobble filter material, drain pipe, blast pipe etc. form the standardized whole of a module, can remove wantonly.

The utility model has the advantages that: the standardized shaft of module can remove wantonly, according to the demand of landfill, adjusts the length, width, the height of shaft module wantonly, and the shaping is standardized, and the shaft after the module is standardized is difficult for the inflation, the stability of the shaft that very big improvement.

Detailed Description

The following is merely an illustration of the structure of the present invention, and various additions or substitutions to the described embodiments by those skilled in the art are intended to fall within the scope of the present invention.

The embodiment of the utility model provides a various part structures are not drawn according to corresponding proportion.

Fig. 1 is a perspective view of the utility model discloses a well for collecting landfill gas, it includes:

the frame structure of the vertical shaft is characterized in that the frame of the vertical shaft is a circular double-cylinder hollow structure type vertical shaft made of steel, and an outer layer 1 and an inner layer 2 of the vertical shaft are formed by iron wires;

the grid specification of the iron wire net is 1-2 cmm;

pebble 5 filter material is filled between the outer layer and the inner layer of the vertical shaft;

the specification of the pebble 5 is 2cm-5 cm.

Figure 2 is a sectional view of the utility model discloses a well for collecting landfill gas, it includes:

the gas collecting pipe 3 is used for collecting gas generated in the vertical shaft;

the drain pipe 4 is used for collecting percolate generated in the vertical shaft and solid impurities;

all the above components are combined together to form a modular standardized shaft.

Embodiment figure 3 is the utility model discloses the application of shaft is shown, it includes:

the standardized vertical shaft of module is placed in a refuse landfill, the vertical shaft is wrapped by a refuse pile body formed on the periphery of the vertical shaft, a bentonite layer is arranged on the refuse pile body, the upper end of the vertical shaft is tightly covered by a cover plate 6, and the sealing performance inside the vertical shaft is ensured.

In the above embodiment, after the landfill is carried out for a period of time, the microbial reaction and the microchemical reaction occur in the landfill to generate gas and leachate, and under the action of the gas and liquid properties, gravity and the like, the gas and the liquid continuously permeate into the shaft through the pores in the pebble filter bed, the gas in the shaft is discharged through the exhaust pipe 3, and the liquid in the shaft is discharged through the drain pipe 4.

Rubbish blows in the landfill, shines, and continuous extrusion, deformation can cause the impact to the shaft, because the utility model discloses a standardized module is made to steel and iron wire netting etc. has certain resistance to deformation and compressive capacity, and the stability of the shaft of very big improvement has improved the life of shaft.
