Abstract
The invention relates to a connected and fixed film cover-screen garbage biogas system. According to the invention, a large-area leakage-preventing cover screen is spliced by using cheap cloth-film large-area films (which can be spliced by using waste objects); a large amount of garbage surrounded by walls can be covered, and the garbage can be turned into biogas and can shrink in a sealed space, such that biogas can be produced and can be applied. The method is especially suitable to be used for digesting garbage piles in landfills produced within years with a backward method, and a simple and easy method for produce energy by using wastes is developed. Soft pressure pipes for storing water and for pressurizing is adhered and connected to the outside of periphery of the cover screen, such that the edges of the cover screen do not curl from the ground. A convex ring is provided outside, such that earth which assists in providing large uniform pressure intensity can be used for enhancing sealing and reducing pollutant leakage. 8 chimney pipes are provided in the cover screen, such that a proper space can be formed by supporting, and biogas can be produced; and biogas can be delivered outwards by using the pipes with ports at relatively high positions. A pump is communicated at the lower part of the chimney pipe, such that biogas discharging can be promoted, and gas or liquid assists in producing biogas can be sprayed in. A proper pressure intensity assisting the cover screen to resist external forces can be maintained, and high-pressure leakage can be provided. Therefore, the system is less annoying, such that a building address is easy to select. The system provided by the invention is comprehensively better and cheaper than a garbage incineration method.
Description
Technical field:
The present invention is device and the using method thereof that a kind of rubbish of honest and clean accumulation easy to digest removes to produce biogas.
Background technology:
At present, treating refuse has become city a great problem, spends huge.
Summary of the invention:
For Lian Yi environmental protection ground treating refuse again, especially tackle the garbage mountain forming piling up landfill yard, the invention provides a kind of folder connection film lid curtain formula rubbish natural pond system.
The present invention solves the technical measures that its technical problem adopts: on bulky refuse [mountain] heap, with several large-area films of connection spelling such as many cover bolt clamp bars, form huge lid curtain and cover rubbish, and add soft pressure pipe vertical being affixed in place, ground of lid curtain, in good time bath press seal gap, form the anti-soft act of volume sealing up letting out dirt of trying one's best and under the condition that is specially affixed by starter and suitably prepares burden, accelerate natural pond by rubbish, output inflammable gas is exported through pipeline.
The invention has the beneficial effects as follows:
As long as 1, Jian Lianyi is universal---call enough [it is much cheap superfluous conventionally having] soft flaps or even junk etc. and form suitably lid curtain, just easily under various terrain environments, tackle former accumulating or newly-increased garbage mountain, easily in various places, implement.
2, can not draw the difficulty that makes new advances greatly---because of without adopting high-temp combustion wave and artificially raise in a large number the means of spreading, first adverse consequences effectively can be confined to originally pile up in the scope of rubbish, can not excite the outer benefit of dirty evil spirit, more can not burn Dioxins.And its alcohol process relaxes easy control, one has bad phenomenon easy to control.
3, environmental and durable easy care---do not need to employ investment hardware and capital construction, need not increase the energy newly, as long as use the cheap materials such as several films to cover rubbish, more do not need to employ a large amount of chemical.Its main body is mainly that the impaired chance of lid curtain is little, even damaged, also very easily paste and mends.Therefore easily continuously long term operation, has even processed also can move to cover after lid scrap heap and has removed to process other scrap heap, seldom needs again people to take care of.Seldom, even the biogas of output can be for external application just to make money to compensate for and have a surplus its maintenance operation expense.
Easily addressing is promoted---and because rubbish 11 being had to omnidistance sealing, even rainwater is also difficult for controlling after its dirt excessive in a large number again, is not subject to the place of water logging to be also not difficult to build near refuse tip → even resident also can accepts reluctantly therefore all, also can consider to be located at hill top.
Accompanying drawing explanation:
Below in conjunction with drawings and Examples, the present invention is further described:
Fig. 1 is that the folder connection film proposing according to the present invention covers an act work schematic diagram for formula rubbish natural pond system.Fig. 2 is that the A of Fig. 1 is enlarged into the view of 4 times to part, and Fig. 3 is that the B-B of Fig. 1 is enlarged into the sectional view of 3 times to face part, and Fig. 4 is that the C of Fig. 1 is to view.
In figure: 1, ridging; 2, soft pressure pipe; 3, thru-bolt; 4, enclosure wall; 5, frame; 6, windlass; 7, jaw; 8, take off frame; 9, guy rope; 10, ground; 11, rubbish; 12, lid curtain; 13, nut; 14, pad figure; 15, clamp bar; 16, bolt; 17, cap; 18, chimney pipe; 19, sterilizing agent; 20, big nut; 21, pump; 22, bent pipe; 23, hinge; 24, pawl rope; 25, support hinge; 26, strut; Dotted line represents the line of vision of all inclinations in soft long strip shape thing, the figure such as rope, Yi Bian all rotation draws to being parallel to drawing again.
Embodiment:
As figure: with tearing parapet 4 that the construction waste that comes etc. is built into open rubbish 10 corrals, under the prerequisite that does not increase contradiction newly, rubbish 11 is increased whereby and piled many hillock shapes on the ground 10 of heap garbage 11, can subtract and take ground as far as possible.In each hill-side, pulling open suitable spacing again establishes the chimney pipe 18[of some chimney-like and can be transformed into by old pipe]---perpendicular or oblique or sheerleg shape allows a port stick up above 1 to 1.5 meter of rubbish 11 and side foreign material---on this port, also answer covering to establish to connect can anti-rubbish and rainwater but do not hinder the cap 17 that gas enters chimney pipe 18.Rubbish 11 nature of this accumulation can macerate biogas and long-pending be exposed to lid curtain 12 internal volumes compared with neutral gear [normally higher] locate again through 18 outputs of chimney pipe for.
For anti-rubbish 11, macerating the reptile disturbs outward, can be outside the heel that is posting enclosure wall 4 a great circle loopful put useless honest and clean pitch or other thickness chemical waste [but should coordinate herein relevant factor in case toxic let out excessive, in full with] sterilizing agent 19 that forms of lethane goes along with sb. to guard him.For anti-this encloses the interior beyond the region of objective existence of ring, let out again again, can allow and cover periphery comprehensively the hang down subsides ground 10 of curtain 12 outside enclosure wall 4; And these lid curtain 12 peripheries outer [on] side paste connection above by thicker flexible pipe [its external diameter should be greater than 10cm or by many young tube side-by-sides, formed thicker, old also can] cause the soft pressure pipe 2 that can fill water storage to help chow ring to press; In the outside upper ridging 1 that adds [but should not contain the hard thing of bulk] such as silts of soft pressure pipe 2, being also into ring is again pressing.So far in lid curtain 12, [chamber] also cannot leak even if gathered the slightly large biogas of pressure; Raining, it is excessive in a large number more also can not to be stained with after its dirt.
For chimney pipe 18 can more conveniently be worked effectively, preferably in the top of chimney pipe 18 appearance, add the upper end of the strut 26 of the articulated elongated rod shape of support hinge 25 forms with hinges.Form one " people " font and quarrel, straddle in rubbish 11 tops.And make the lower end card of chimney pipe 18 and strut 26 insert in ground 10, and top attitude even all easily regulate change in position, to reach good effect.The lower end of chimney pipe 18 preferably also the subsidiary pump 21 → be communicated with again of being communicated with can be communicated with the extraneous bent pipe 22 that shriveled by foreign object of being difficult for again; Just can send or pump into the fluid that some help rubbish 11 more effective natural ponds outside by more effective pump biogas.Be sprayed under lid curtain 12.And that bent pipe 22 should be able to allow to do is suitably crooked and do not lose efficacy, to be matched with the displacement of chimney pipe 18 may.
For allowing rubbish 11 general natural pond sooner, can suitably locate the horizontal horizontal through hole that drills containing wearing the large pad that thru-bolt 3 adapteds are soft and hard [normal thing of this letter at enclosure wall 4, in figure, omit, in full with] add that big nut 20 is the frame 5[back side of supporting windlass 6] be fixed on enclosure wall 4, then allow between every pair of windlass 6 on mirror image opposite around upper two can synchronous reciprocating translation the guy rope 9 done of tough long rope; Allowing approximately 3 to 5mm thick iron plates cause rectangle is the stage casing that each long limit, the back side of taking off frame 8 of main leaf shape is fixed on a guy rope 9 again; Take off a certain minor face of frame 8 with hinge 23 jaw 7 that is being hinged alive.The configuration of jaw 7 is roughly the same taken off frame 8, it is much shorter, its relative free end mid point of two, be respectively each one end of connecting the pawl rope 24 that short tough rope makes → to make its angle limit between two between 0 °～90 °, change → and when this angle is 0 °, its molectron of two should be as far as possible little along the direction projection area of guy rope 9, is subject to resistance while being dragged to subtract; When this angle is 90 °, corresponding area strain, to larger, is dialled rubbish 11 to more effectively take off.
So far, when allowing the windlass 6 of forward [set with the C of Fig. 1 to contrary] receive around guy rope 9, jaw 7 will more efficient forward take off group rubbish 11; Reverse windlass 6 is received when guy rope 9, jaw 7 grades are reversed and are dragged to reset, the less rubbish 11 of stirring.Thereby both can dial loose rubbish 11[easily controls the stroke of guy rope 9 or even shifts windlass 6 and the orientation of guy rope 9 or be opened in the windlass 6 in another orientation and guy rope 9 etc.A certain scope is only stirred in restriction] to help natural pond, can dial and make rubbish 11 high to a certain scope heap towards a direction [forward] again.If will oppositely implement above-mentioned taking off, dial, easily establish and a set ofly reverse take off frame 8[as long as along 180 ° of self large planar inverted] and accessory realize.
Again preferably: take off the large plane of frame 8 and jaw 7 and the axis of windlass 6 and be all perpendicular to horizontal plane, two guy ropes 9 configure one on the other, this both can more subtract working resistance, also be expected to allow and take off frame 8 grades in repeatedly moving back and forth, work is gone in the depths that is progressively inserted into rubbish 11 heap Duo from higher position downwards.
For reaching object of the present invention, preferably accomplish: by the soft flap of cheapness, be unified into large-area leakage-proof cover curtain 12 and be covered with outside a large amount of rubbish 11 in low simple enclosure wall 4 circles to help natural pond; Wherein by two width or several soft flaps and be unified into area and surpass 1000m
2lid curtain 12 be covered with outside the rubbish 11 on the ground 10 in enclosure wall 4 ring of encirclements; In lid curtain 12, be also provided with a port and than rubbish, exceed the chimney pipe 18 of rigidity elongated tubular more than 0.3m.Each the soft flap paving that forms lid curtain 12 is one unilateral to rubbish 11, all along the length of side is upwards perpendicular, turns up wide 1 to 9cm slat and is close to an adjacent soft sheets this upwards erects another corresponding slat of turning up; And the clamp bar 15 that curves " ∩ " shape with rectangular thing clips top outside, and allow bolt 16 or rivet or metal strip pass across to join after these three things nut 13 is twisted folder or riveting joins.Lid curtain 12 hangs down and is affixed on outer subsides of ground 10 peripheries and is joining length and surpass 100m and can fill the soft pressure pipe 2 of storing into the hose-like of 200 liters of above water.The lower end of chimney pipe 8 is being communicated with pump 21 and is being communicated with the external world that bent pipe 22 removes to be communicated with native system more again.In enclosure wall 4, being provided with windlass 6 moving guy ropes 9 goes to drag with the live plate-like frame 8 of taking off of articulated jaws 7 of hinge 23.Soft pressure pipe 2 is being pressed by the husky ridging 1 that accounts for weight 80% above.Take off the large plane of frame 8 and the axis of hinge 23 is less than 20 ° separately with along the folded acute angle of vertical line.When taking off frame 8 and dragged to certain direction, the angle of it and jaw 7 is less than 20 °, when taking off frame 8 when direction is dragged in contrast to this, and the folded acute angle of it and jaw 7 is 60 ° to 90 °.
