Fig. 2 is the utility model anaerobically fermented city life garbage apparatus structure annexation vertical view.
[embodiment]
Below in conjunction with drawings and embodiments the utility model is further specified.
Referring to Fig. 1, Fig. 2, the anaerobically fermented city life garbage device, comprise fermentation cabin, be used to store the dumper 4 of rubbish, drive the transmission mechanism 20 that described dumper 4 moves in described fermentation cabin, the rubbish of installing in fermentation cabin that is used for storage in described dumper 4 is dosed the spray equipment of anaerobion and is used to detect the fermentation cabin temperature, the detection control apparatus of anaerobion potential of hydrogen, fermentation cabin is by feeding warehouse 2, produce acid phase 15 by the hydrolysis in the anaerobic reaction, produce oxygen and produce the acetate stage 14, produce the anaerobically fermenting main reaction storehouse 8 that methane phase 13 is formed, with go out feed bin 9 and form.Wherein, anaerobically fermenting main reaction storehouse 8 seals, and can prevent that the warehouse air outside from entering and the effusion of internal gas, establishes gas skirt and air outlet 5 at the top of fermentation cabin, and the biogas that anaerobic fermentation becomes is discharged and collected by air outlet 5.Feeding warehouse 2 and the setting that goes out feed bin 9 are in order to guarantee that whole anaerobic fermentation system can realize the desired continuous operation of suitability for industrialized production, to guarantee that the rubbish of every day can both be handled timely.
When the charging of anaerobically fermented city life garbage device, dumper 4 is at first by lifting, be installed in the fixed position of feeding warehouse 2, close feeding warehouse external door 20 then, open the inside door 19 of feeding warehouse again, close out the external door 10 of feed bin then, open out the inside door 11 of feed bin again, this moment feeding warehouse 2, go out feed bin 9 and anaerobically fermenting main reaction storehouse 8 and be communicated with.Transmission mechanism 20 is made up of electric motor 1, drving sprial 3, by the rotation of electric motor 1, drives spiral 3 rotations, again by the rotation of spiral 3, drives dumper 4 and travels forward.Rotation time and rotating speed by control electric motor 1, can control the travel distance of dumper 4, when dumper 4 marches to preposition forward, electric motor 1 stall, dumper 4 equal forward direction are even has at this moment moved lattice, has replaced a dumper 4 residing position before travelling forward, front.At this moment, close the inside door 19 of feeding warehouse and go out the inside door 11 of feed bin, and then open the external door 20 of feeding warehouse and go out the external door 10 of feed bin, after the ventilation, be arranged in feed bin dumper be exactly the rubbish of finishing behind the anaerobically fermenting, transported by lifting.
Dumper 4 open tops, bottom are provided with sieve aperture formula structure 23, and what be convenient to percolate oozes discharge down, dumper 4 bottoms are provided with wheel, be provided with and the corresponding screw thread 24 of drving sprial at the axis place simultaneously, when spiral 24 rotates, can drive dumper 4 and advance.
Spray equipment is made up of leachate collection bucket 16, leachate collection case 18, percolate transferpump 12, percolate transfer lime 21 and spray header 7.When dumper 4 is arranged in anaerobically fermenting main reaction storehouse 8, the percolate that produces oozes to leachate collection bucket 16 under discharging by the sieve aperture structure 23 of dumper 4 bottoms, enter in the percolate collection box 18 of sealing, lifting by percolate transferpump 12, through percolate transfer lime 21, finally, enter in the dumper 4 by spray header 7 ejections.Contain abundant microorganism in the percolate, can be by the spray of returning of percolate effectively to the generation of the rubbish in dumper inoculation effect (microbial cultivation process when being added to bacterial classification in the rubbish), the speed of raising anaerobic reaction.
In the anaerobically fermented city life garbage system, the anaerobic reaction process of rubbish has been carried out the division of syllogic, and wherein first section is that to produce acid phase 15, second section be that to produce acetate stage 14, the 3rd section be to produce methane phase 13 for product hydrogen in the anaerobic reaction for hydrolysis in the anaerobic reaction.The collection bucket 16 of percolate and collection box 18 are established three groups, percolate transferpump 12, pipeline 21 and spray header 7 also are made as three groups accordingly, wherein, the percolate of first section generation returns in the dumper that is sprayed onto the 3rd section, the percolate of second section generation returns in the dumper that is sprayed onto second section, the percolate of the 3rd section generation returns and is sprayed onto in first section, it is because first section microbe population is less relatively that the spray that interlocks is back like this handled, second section abundanter through the content of microorganisms in the reaction percolate of first section of front, the 3rd section reaction owing to earlier stage, the content of microorganism is superfluous in this stage percolate, at this moment the purpose of spraying of interlocking back is the organic content and the microbe population of three sections of regulation and control, promote whole anaerobically fermenting speed of reaction.In the percolate collection box, be provided with the overflow structure, when the percolate of storing reaches certain amount, can efflux unnecessary percolate by overflow device 17.
Detection control apparatus mainly comprises temperature monitor and pH value monitor, by the monitoring to the fermented storehouse of the rubbish temperature, can promote speed of reaction so that rubbish carries out anaerobically fermenting at optimum temps 30-36 degree centigrade.Simultaneously, the pH value of the percolate that reflects by pH value monitor, can check rubbish whether to be in optimum response pH value, depart from if having, can be by adding acid or adding the percolate pH value that alkali is regulated back spray, rubbish pH value in the dumper is regulated, and the system of assurance is in best running environment.
Above-mentioned detailed description only is exemplary description, and those skilled in the art can design various embodiments according to different actual needs under the situation that does not break away from the scope and spirit that the utility model protects.
