Abstract

The utility model discloses a methane-collecting cover for collecting the methane in the open methane fermentation pool. The utility model comprises a cover body, a gas-guiding outlet positioned on the top of the cover body and a reinforced frame positioned under the cover body. A plurality of connecting mechanisms are positioned on the reinforced frame in order for the reinforced frame to be fixed on the upper wall of the methane pool. A feeding pipe is added on the sidewall of the cover body, and a pressure-regulating pressure plate is added on the top of the cover body. The utility model has the advantages of low construction cost, safe and convenient use and quick production of the methane, and can regulate the air pressure and store the remaining methane.

Description

A kind of methane gas-collecting hood
Affiliated technical field
The utility model relates to a kind of gas skirt of collecting the biogas in the open type marsh gas fermentation pool that is applicable to.
Background technology
The enclosed construction that the existing methane-generating pit of generally promoting all adopts the pond body to add a cover is generally built by laying bricks or stones with materials such as concrete, masonries and is formed.It mainly contains following shortcoming: 1, the pond body needs integral body airtight, and laid down cost is higher, in case leak air, the pond body is promptly scrapped; 2, because discharge port is less, the clear pond of discharging needs the people to enter operation in the pond, and is both inconvenient, also dangerous; 3, owing to seal for a long time, the long-term static easy crust of natural pond liquid liquid level influences aerogenesis in the pond, and its factor of created gase is low; 4, build the pond and need site operation, can't realize batch production production.
Technology contents of the present utility model
Problem to be solved in the utility model is to provide a kind of gas skirt of gathering biogas in the open type marsh gas fermentation pool.
The utility model adopts following technical scheme, comprise cover body and be located at the vertical air guide outlet of cover body, the bottom of described cover body is provided with one and strengthens frame, being provided with several around the described reinforcement frame is used to make the upper wall of described reinforcement frame and methane-generating pit to be fixedly coupled mechanism, described connection mechanism is positioned at below the liquid liquid level of natural pond in the time of can making described reinforcement frame in working order, thereby keeps air storage spatial water seal air-tight state in the cover body.
As improvement of the present utility model, also comprise the feed-pipe of being located at close described reinforcement frame on the faceshield side wall, described feed-pipe internal orifice is positioned at below the liquid liquid level of natural pond during working order, thereby keeps cover body air storage spatial water seal air-tight state.
As further improvement of the utility model, described connection mechanism is fixing catch or the wire or fasten the tie lines rope twisted together, also having a kind of improvement is that cover body of the present utility model is made by bag material, and its air storage spatial volume has certain retractility, is beneficial to and regulates air pressure, stores residual air.
Employing the utlity model has following advantage:
1, laid down cost is low.The utility model is simple in structure, is easy to processing, and cover body adopts deformable soft material or the processing of one-time formed mechanically resistant material all can.Both can use plastics, rubber, synthetic textiles or other similar gastight bag material to make, but also materials such as glass reinforced plastic, glass fiber material, metal are made.One is used for pond open area 8m 2The gas skirt of fermentation vat, be equivalent to old-fashioned methane-generating pit 15m 3The aerogenesis function, its production cost adds that below 100 yuan newly-built fermentation vat total cost about 600 yuan, reduces cost 2/3rds than old-fashioned methane-generating pit.
2, supporting fermentation vat structure is had no special requirements, be easy to promote.Only needing a degree of depth is that non-leakage common manure pit more than 50 centimetres gets final product.Its pond degree of lip-rounding shape is not limit, and can be multiple shapes such as circle, ellipse, rectangle, and the stiffened edge shaped as frame shape of cover body can be corresponding shape with pond degree of lip-rounding shape.The utility model also is suitable for the sewage fermentative processing in town domestic sewage and plant, slaughterhouse, can build a plurality of fermentation vats, uses a plurality of gas skirts to take turns air feed.
3, safety easy to use.Overhead about 3m, discharging needs the people go into the pond operation, and is both inconvenient, easily goes out security incident again at the bottom of the old-fashioned methane-generating pit pond.Use the utility model, building tank depth only needs about 1.5m, removes cover body during discharging and gets final product open work, very convenient safety.
4, aerogenesis is fast.After reloading, old-fashioned methane-generating pit need five to ten days ability to arrange that the assorted gas in the air chamber formally uses in the pond.Use the utility model, once arranged air in the cover in the liquid of natural pond, install and formally to come into operation in one to two day because the cover body of gas skirt can all immerse.Install evening can use morning during summer.
5, if cover body is when making of flexible materials such as bag materials, and its air storage spatial volume has certain retractility, presses by the adjustable solar term of pressure regulation pressing plate, and its aerogenesis the utility model for a long time also can serve as the reservoir hag use.
Below in conjunction with embodiment the utility model is described in further detail.

Fig. 2 is the utility model installment state (not aerogenesis) synoptic diagram.
Fig. 3 is the utility model gas collection principle of work synoptic diagram.
Embodiment
As shown in Figure 1 and Figure 2, the utility model comprises: cover body 1, be located at cover body 1 vertical air guide outlet 2, the bottom of described cover body 1 is provided with one and strengthens frame 3, be provided with several around the described reinforcement frame 3 and be used to make the described reinforcement frame 3 and the upper wall of methane-generating pit to be fixedly coupled mechanism 4, described connection mechanism 4 is positioned at below the liquid liquid level of natural pond in the time of can making described reinforcement frame 3 in working order.Adopt the purpose of strengthening frame 3 to be to support cover body 1, be convenient to install, and guarantee that installation rear cover body 1 remains the water-lute state.
Improved procedure of the present utility model as shown in Figure 1 is to have set up the close feed-pipe 5 of strengthening frame 3 on cover body 1 sidewall, and it is even that the gas skirt of this structure is fed into the pond, and factor of created gase is higher.
In addition, described connection mechanism can adopt multiple mode, as fixing catch, stay hook, kink wire, fasten tie lines rope or the like, also having a kind of improved procedure is that cover body of the present utility model can be made by bag material such as plastics film, rubber or other air-locked slim soft material, there is certain retractility in its air storage space, a pressure regulation pressing plate can be set up in the cover body top, when air pressure is not enough, press down this pressing plate and can play supercharging, when air pressure is big, can remove this pressing plate, making cover body be in extended configuration can reduce pressure as far as possible.
The utility model is not limited to the concrete structure of the foregoing description, and the equivalent transformation of other similar structures all falls within the protection domain of the present utility model.
