1. A kind of 1. fermentation process using dry method fermentation system, it is characterised in that:

  • The dry method fermentation system include with import,Discharging opening(

    45)

    And the fermentation the library of gas outlet(

    2)

    , positioned at fermentation the library top side, the discharging opening is located at for the importThe fermentation one end of the library bottom away from import, it is characterised in that:

    The fermentation the library bottom is equipped with from below import to discharging openingConveying worm(

    43)

    , the import top is equipped with feed arrangement(

    3)



    The feed arrangement contains syphon shape piston cylinder(

    18)

    , vertical section of lower end of the piston cylinder and inlet communication, the horizontal segment of the piston cylinder is built with reciprocating mechanism(

    23)

    The piston of driving(

    19)

    , the horizontal segment top is provided with funnel-form charging aperture(

    20)



    The fermentation the library is by the library inner bag inside(

    14)

    With the water-bath the library being wrapped in outside the library inner bag(

    12)

    Form, it is describedOne jiao has water inlet at the top of water-bath the library(

    13)

    , one jiao away from water inlet of the water-bath the library bottom has delivery port(

    15)

    , the delivery port passes through through boiler(

    11)

    , heat-exchanger pump(

    10)

    Exterior line lead to water inlet;

    The library inner bag is neighbouringOne end bottom of discharging opening has grid leak plate(

    25)

    Biogas slurry pond(

    26)

    , the library inner bag top is equipped with and is attached to elevating mechanismOn broken shell injection mechanism(

    24)



    The main broken shell injection showerhead by being distributed on infusion pipeline of the broken shell injection mechanism(

    28)

    Form, the biogas slurry pond passes through biogas slurry delivery pump(

    27)

    Biogas slurry pipeline connect the biogas slurry input port of broken shell injection mechanism(

    29)



    The elevating mechanism includes being fixed on the library inner bag end and vertical rack(

    37)

    Form the rack guide rail of prismatic pair(

    35)

    And with the rack(

    37)

    Engagement and intermeshing vertical arrangement gear train(

    36、

    38、

    40、

    41、

    42)

    , the rack(

    37)

    Pass through fixture(

    39)

    With broken shell injection mechanism(

    24)

    Infusion pipeline be connected, the driving gear in the gear train(

    36)

    With passing throughTransmission device(

    33)

    With motor(

    31)

    Drive connection;

    The transmission device has coaxial rotational handle(

    32)



    The reciprocating mechanism is crank connecting link reciprocating mechanism(

    23)



    The water-bath the library(

    12)

    Inner surface and the library inner bag(

    14)

    Outer surface is respectively provided with heat-insulation layer(

    16、

    17)



    The fermentation process comprises the following steps:

    The first step, conveying charging --- start the reciprocating mechanism of feed arrangement, the fermentation raw material for inputting charging aperture is inputtedIn the library of fermenting;

    Second step, temperature controlled fermentation --- starting trouble and heat-exchanger pump carry out heat exchange, keep the library inner bag to be bathed in required fermentationIn the hot water of temperature, the library inner bag is uniformly heated, fermentation raw material is fermented, biogas is exported by gas outlet;

    3rd step, spray promote ferment --- and start biogas slurry delivery pump, the fermentation raw material in the library inner bag is sprayed, form biogas slurryCirculation, promote fully fermentation;

    4th step, surface broken shell --- start elevating mechanism, the broken shell injection showerhead of broken shell injection mechanism is pierced into fermentation raw materialTop layer, by biogas slurry sprinkling be expelled in fermentation raw material, further promote fully fermentation;

    5th step, output biogas residue --- fully after fermentation, start conveying worm, the biogas residue source after the library liner at the bottom is fermentedSource constantly exports from discharging opening.
