Described subsidiary conduit 63 is interspersed in described flexibility continuously and covers in the peripheral ready-formed pipe box 202 of skin 20, supporting flexibility covers skin 20 and makes it to be evenly distributed on the fermentation vat of anaerobic fermentation reactor 10, improve the flexible stressing conditions that covers skin 20, this subsidiary conduit 63 can be avoided covering perforate on the skin 20 in flexibility, prevents that flexibility from covering skin 20 cracking phenomenas and taking place.Described fixedly buckle 62 is easy for installation, dismounting flexibly, fixedly the position of buckle 62 can be covered skin 20 inflated configuration with described flexibility and adjusts automatically, makes each link up with 61 and is in best strained condition.Described hook 61 is with horizontal short handle 625, conveniently is bonded to described uncovered anaerobic pond periphery; The crotch of 270 ° of circular arcs, radian is big, and towards to cover the expand pulling force that produces of skin 20 opposite with flexibility, can effectively prevent belled buckle obscission.With the carrying out that anaerobically fermenting reacts, gas constantly generates, the effusion liquid level, and the pond internal gas pressure constantly rises, and flexibility is covered skin 20 and is outwards expanded, expands under gas pressure, is subjected to the stationary installation restriction and is covered in the pond face, is not shifted.During dismounting, fixedly buckle 62 is taken off one by one from linking up with on 61, and flexibility covers skin 20 and subsidiary conduit 63 just can relatedly draw off.

Principle of work of the present invention:

The novel vertical flexible covering film anaerobic fermentation device of this structure, sewage enters concentric annular water distributing area 232 from the water inlet pipe 21 of described multi-point self-rotating water-distributing device 2 by center tubing string 31, two water distributors 22 about being evenly distributed to, spray from each spray orifice 222 with certain flow velocity, spray orifice 222 flow velocitys 3～6m/s, current slowly rise in reaction zone 3A, upflow velocity＜1m/h, and HRT is long; Jet produces deboost to water distributor 22 in the course of injection, because two water distributors, 22 perforate directions are tossed about, the moment of generation deviates from the rotation of spray orifice 222 directions thereby drive described multi-point self-rotating water-distributing device 2 moving parts around axis in the same way; Spray orifice 222 even water outlets, water distributor 22 uniform rotation, thus guarantee that water distribution all measures in the equilibrium of whole anaerobic fermentation reactor 10 and even each water distribution spray orifice 222, realize that anaerobic fermentation reactor 10 water distributions are in the space and temporal homogeneity.The rotation of the injection of current and multi-point self-rotating water-distributing device 2 produces waterpower simultaneously to peripheral muddy water and stirs and mechanical agitation, promotes muddy water to mix.Described multi-point self-rotating water-distributing device 2 below biogas whipping apptss then evenly penetrate biogas from pore with higher relatively speed, forming the intensive air-flow stirs, and significantly forming strong convection current up and down under gas, the effect of liquid density difference, force current to form a plurality of little vortexs by each to disturbance, flow at entire reaction district 3A internal recycle, the interior muddy water of reaction zone 3A is mixed fully, microorganism contacts with organism well, degraded, gas production rate improve, and effectively prevent heavy mud at the bottom of the pond.Carrying out along with the anaerobically fermenting reaction, the interior gas of reaction zone 3A generates and carries muddy water mixed solution in a large number and rises along the pond body together, merging density along with bubble in the three-phase mixed solution uphill process reduces gradually, constantly upwards flow, until arriving anti-aeration plate 32, gas is folded to gas collection district 3B, rise to liquid level, be discharged into air chamber, import tracheae by the getter hole and discharge, separate with solid, liquid; Bubble is carried small-particle mud and slag come-up secretly at uphill process and is flowed into gas collection district 3B in the lump, forms scum silica frost and floats on the solution-air surface, is discharged by ash pit 35, and the moving peripheral scum silica frost of broken belt flows to ash pit 35; Mud part after separated from the gas falls after rise to reaction zone 3A, and a part is gone into head piece with fluid along negative area 3C and entered exhalant region 3D under the guiding of flow deflector 33, does the flow lifting type precipitation, sedimentation speed 1～2m/s.In the 3C of negative area, mud granule active low, quantity is few, and organic concentration is low, and aerogenesis is very little, and is little to the solid-liquid separation influence; Owing to eliminated the castering action of gas, mixed solution slows down gradually in uphill process speed, realizes mud-water separation by mud, water self difference of specific gravity, improves SRT greatly, clear liquor is crossed aquaporin 37 overflows to V-notch weir 38 by 36 of ash pit 35 and effluent troughs, is discharged by water outlet skirt 3120; Sludge settling is to anti-aeration plate 32 inboards, along the wall landing to the mud refluxing opening and through reflecting the vertebra uniformly distributing to reaction zone 3A; Returned sluge does not contain gas, proportion is big than reaction zone 3A mixed solution, form circulating fluidized with reaction zone 3A ascending current, promote that mud granule fully contacts with organism, thoroughly reaction, the heavy mud of part is concentrated to tank base central row bucket 315 under waterpower promotes gradually, is discharged by spoil disposal skirt 3140.Increase along with gas among the gas collection district 3B, flexibility is covered skin 20 and is expanded gradually and heave, be hemispherical, firmly be fixed under the effect of stationary installation 6 above the anaerobic fermentation reactor 10, fixed area edge current overflow along seam, form certain water seal liquid level, make whole device be in air-tight state, to keep constant low pressure anaerobically fermenting environment.
