New mobile fermentation biogas digester

technical field

The utility model relates to a fermentation biogas pool, in particular to a novel mobile fermentation biogas pool.

Background technique

At present, the production of biogas is produced by fermentation and accumulation in fixed fermentation tanks on the ground. These biogas digesters can only be carried out in hard and fixed places, and cannot be moved or relocated to adapt to changes in conditions and environments. It is not conducive to the collection and utilization of waste materials, affects production, limits development, and hinders vigorous promotion and comprehensive utilization. Improve and perfect.

Contents of the invention

The purpose of this utility model is to provide a new type of mobile fermentation biogas digester which can adapt to various environments and conditions, can be moved and relocated, and flexibly set up soft fermentation ponds according to local conditions, and ferment in the ponds to generate biogas.

In order to achieve the above object, the technical solution of the utility model can be realized as follows: a novel mobile fermentation biogas digester comprising a fermentation tank, a hydraulic tank, a slag cleaning tank, a feed inlet and an air duct, wherein the fermentation tank is a plastic Portable soft body pool, the soft body pool can be a soft bag made of plastics or rubber, and the soft bag is covered in the pool surrounded by a hard protective body.

Described soft bag can have cube, cuboid and cylinder.

The lower side of the soft bag is provided with a feed inlet with a pipeline structure, and an air duct for air outlet is provided at the upper end.

The hard protective body is adapted to the soft body pool, and may have a protective body surrounded by cement bricks, plastics, wooden boards or metal plates.

Wherein the water pressure tank is connected to the fermentation tank by a water pressure pipe, and the fermentation tank is connected to the slag removal tank by an automatic slag removal valve.

Because the utility model adopts a movable and relocated soft fermentation tank, it can discharge biogas slurry and biogas residue from the bottom of the tank, avoiding the trouble of manual cleaning in the tank regularly and saving labor; the utility model adopts the setting of the feed port and the water pressure tank with a pipeline structure , so that the feeding and discharging are always balanced, so that the gas production and air pressure are always kept stable, ensuring the stability of gas supply and gas consumption, setting up automatic slag discharge valve and slag cleaning tank, which can automatically remove slag and sewage without going into the tank Slag removal operation overcomes various accidents such as poisoning, and also solves the problem of difficult fermentation due to cold weather and low temperature in the north, ensuring safe and stable production; simple equipment, easy installation, easy maintenance, and flexible operation. It is easy to move and relocate, quick to produce gas, and low in cost. It is an effective way to save energy, protect the environment, and reduce consumption.

Detailed ways

Now illustrate with reference to accompanying drawing and embodiment.

As shown in Fig. 1 and Fig. 2, according to needs, the size and specification of the soft body fermentation tank 2 can have soft bags 8 of various specifications and sizes, and then become cubes, cuboids, cylinders, etc. after inflation. According to these specifications, the hard protective body corresponding to its size can be adapted (in Fig. 2, the feed inlet 1 and the air duct 7 are not shown because the outer wall is surrounded by the hard protective body), that is, cement bricks can be built. Can accommodate the cement pool of these corresponding size soft bags, or make the corresponding hard protection body with the size of soft bag 8 with plastics, planks or metal plates such as iron, aluminum etc., put these plastic soft bags 8 Among them, cover with top cover 15 again on the face, in order to safety. When needing to move, make corresponding hard protective body in different places, soft bag 8 is placed wherein then can reuse. When in use, the material enters from the feed port 1 with a pipeline structure, and the fermented material has been fermented under a completely sealed condition. After a certain amount of fermented material is filled, gas (biogas) is gradually generated, and the soft bag 8 is slowly made Bulge to show the inflated shape of the soft body pool, such as cube, cuboid or cylinder. When the inflation reaches a certain amount, the biogas is discharged from the air guide pipe 7 , and the water and gas are separated through the air-water separator 9 along the air guide pipe 7 to form anhydrous biogas and reach the air storage bag 10 . If the user applies, when the pressure is low, the booster pump 11 meters can be used to increase the pressure, and then send it to the desulfurization purifier 12 for desulfurization and purification, so as to obtain pure biogas and burn it in the stove 14. If the gas volume is sufficient and the air pressure is large, the booster pump 11 may not be needed, and the biogas is directly purified by the desulfurization purifier 12 from the pressure-free pipe 13 to the stove 14 for combustion.

In the fermentation tank 2, the material forms three material layers during the fermentation process, the bottom layer is a sediment layer, the middle layer is a clear water layer, and the upper layer is a floating layer. When the material is fermented, the gas generated rises, and when the pressure in the upper space of the upper floating layer reaches a certain value, the air pressure increases, and the biogas is discharged from the air guide pipe 7. After the gas is used, the pressure drops, the floating layer rises, and the water surface of the clear water layer in the middle layer It also rises, and flows from the hydraulic pipe 4 to the hydraulic tank 5, and the sediment also rises thereupon, and the sediment is discharged to the slag cleaning tank 6 through the automatic slag discharge valve 3, and the sediment is discharged from the pool outside the pool. When the material is replenished, the material layer in the fermentation tank 2 rises again. When a certain amount of gas is generated, the air pressure rises, and the biogas is discharged along the air duct 7. After combustion, the air pressure drops, and the three material layers rise again, resulting in the above cycle. effect. Such repeated fermentation produces biogas to achieve the effect of continuous gas supply and use, and becomes a new way of energy utilization that is environmentally friendly, cheap, low-consumption, and energy-saving.
