Description
Technical field
The utility model relates to a kind of garbage loading embeading device, especially garbage loading embeading multiple-limb biogas and leachate integrated exhaust device.
Background technology
At present, biogas and percolate adopt the mode of independent pump drainage in the refuse landfill: biogas is carried out pump drainage by discharge guiding pipe of burying underground in advance or the mode of beating upright opening after closing, enters the liquid collecting well after percolate is then collected by the french drain of landfill yard bottom and pump drainage is gone out.The mode of this independent pump drainage need be carried out engineering construction respectively, and along with the degraded of rubbish, the particle in the percolate stops up the migration pathway of gas, liquid, and the infiltration of rubbish body is given birth to can variation, causes the pump drainage effect of biogas and percolate to become not ideal enough.
The utility model content
The purpose of this utility model is to overcome in the prior art to have problems, a kind of refuse landfill biogas and leachate integrated exhaust device are provided, it not only is convenient to construction, the pump drainage efficient height of its biogas and percolate, and can quicken the stabilizing process of landfill yard.
For achieving the above object, the technical solution of the utility model is: it comprises vertical shaft, that the layering setting communicates with vertical shaft is multilevel, the collection white-out passage of multiple-limb, collect the gravel that is filled with water guide, air guide in the white-out passage, the horizontal plane angle α that multiple-limb is collected white-out passage and vertical shaft increases from the bottom to top gradually; The vertical shaft well head is provided with seal cover, and is provided with the exhaust device that biogas and percolate pump drainage can be fallen.
Described vertical shaft is constructed by Reinforced Concrete Materials and is formed, and hoistway wall leaves with multilevel, multiple-limb and collects white-out channel connection mouth; The height l that described vertical shaft well head exceeds the refuse landfill closing is 300-50mm; Height h between shaft bottom and the drainage blanket bottom is 3000-50mm; Described collection white-out passage is made of the pupa shape basket that a plurality of end to end, biodegradable fibrous material braidings form; The angle α that the horizontal plane of described multiple-limb collection white-out passage and vertical shaft increases from the bottom to top gradually is 5-15 °; Described exhaust device comprises aspiration pump, and the stack in the coupled insertion vertical shaft is located at the submersible sewage pump of silo bottom and connects the gutter formation of stretching out outside the well with it; Described seal cover is provided with aspirating hole that inserts stack and the drain hole that inserts gutter, also is provided with the jack of water-level instrumentation and the jack of pressure monitor.
Owing to be provided with hydropneumatic vertical shaft in refuse landfill, and be provided with horizontal plane around vertical shaft and exist multilevel, the multiple-limb of certain angle to collect the white-out passage, improve the permeability of rubbish body inside, more helped migration and the transporting of gas-liquid in the rubbish body.Because multilevel, multiple-limb is collected the white-out passage and can be carried out incorporate collection of gas-liquid and transporting, therefore collect white-out passage converging by multilevel, the multiple-limb of divergent shape to the center vertical shaft, realize gathering of biogas and percolate, and by pump drainage pump pump drainage.Whole apparatus structure is simple, easy construction, and engineering cost is low, later maintenance convenient management, and convenient internal regulation processing to biogas monitoring utilization and percolate.
