The soft foldable biogas digester is a new type of biogas equipment including soft foldable biogas fermentation bags, biogas storage bags, biogas booster pumps, desulfurizers, water separators, biogas delivery pipes and related pipes.
Soft Red Mud Fabric for foldable Biogas Digester:
Red mud biogas digester refers to a foldable biogas digester made of new technologies and new materials. The main classifications are biogas storage bags and biogas generating tanks (fermentation tanks). Air storage bags are generally divided into cylindrical and rectangular. The generating pool is mainly divided into teapot shape and floating cover shape. The red mud soft biogas digester contains more red mud than ordinary PVC. Red mud rubber is a modified alloy plastic, which is incomparable to ordinary plastics.

Soft foldable biogas digester fabric Advantage
Red mud soft biogas digester Red mud rubber is a modified alloy material, which is unmatched by ordinary plastics.
It has the following characteristics: excellent resistance to light and heat aging, good weather resistance, tensile strength, elongation, penetration resistance, perforation resistance, low temperature flexibility; flame retardancy, thermal stability, heat aging, acid and alkali resistance Good corrosion performance, especially waterproof, corrosion resistance and tensile performance.
Therefore, it is safer to place it outdoors and generally takes longer.
Red mud digester cloth Performance characteristics
1. Economical and durable, low price, low investment, quick effect: the equipment is anti-freezing (-25℃), anti-exposure (50℃),
lightning protection, anti-vibration, anti-aging, corrosion resistance, no leakage, installed in a fully enclosed, It can be used
continuously for 8-12 years without any man-made or external damage. The price is only equivalent to one-third of that of the
cement-casting and FRP-type biogas digesters, and it has developed rapidly in rural areas. Except for the one-time purchase
of equipment, the subsequent investment is almost zero. According to preliminary calculations, a set of 8 cubic meters of
technical equipment that can be used for more than 8 years, the maximum installation cost does not exceed 1,200 yuan,
When the user installs the equipment, after putting the fermented material into the fermentation bag, the gas will be available
24 hours in summer and 96 hours in spring and autumn. Comparing the biogas produced that year with the purchase of coal
gas, and calculating the discount, the full cost of the investment in purchasing the equipment can be recovered.
2. Light weight, foldable, small size, easy to transport and carry, and can be moved and installed at will. The weight of the whole
set of equipment is only about 10-20 kg, which is easy to carry. And the equipment can be moved and installed arbitrarily,
if the user moves to a new house, the equipment can be removed and installed separately.
3. The installation is simple and quick, and the depth of the pit body can be selected arbitrarily according to user conditions.
The main body of the equipment (soft foldable biogas fermentation bag) is made of high-strength plastic material with high
mechanical strength and elongation. It is not restricted by any geographical conditions during installation and can be placed
on a general foundation (such as rural areas). Existing human and animal manure tanks, stairwells in township buildings,
or even a soft soil pit can be used. Even if the foundation of the fermentation tank is shaken or deformed by external forces,
this equipment can work as usual without any influence.
4. No need to stir, high gas production. The body of the fermentation tank is dark and can be exposed to the open air, which is
convenient for absorbing solar energy. The temperature in the tank is high and the gas production rate is also high. A plastic
biogas digester with a volume of about 6 cubic meters is equivalent to a 10 cubic meter hydraulic digester. Gas production.
This kind of biogas digester has great advantages in areas with high temperatures and can be used in solar greenhouses in
winter in northern areas. In addition, because the tank body is made of high-strength soft material, it is very resistant to tearing.
It can be pressed and shaken down at the top of the tank at any time, without stirring, so that the floating matter (ie the crust part)
on the liquid level in the fermentation tank can be immersed Below the liquid level, the problem that the fermented material in the
fermentation tank crusts and affects gas production is solved. Furthermore, the fermented materials put in at any time have been
fermented under a completely closed condition. Therefore, the same amount of fermented materials can increase the gas production
by more than 20-30% compared with the traditional biogas equipment with the same tank capacity.
5. The raw materials used for fermentation are from a wide range of sources: the raw materials are usually people’s domestic garbage,
agricultural waste, etc., such as crop straws and human and animal manure discarded in the vast rural areas; the peels, vegetable peels,
feces, dishwashing water, and bathing of urban residents Water; leftovers from food processing plants, residues from the catering industry, etc.;
generally, farmers can raise more than three pigs to meet living gas.
6. It is very safe to use this equipment: because the fermentation room of the equipment is made of plastic materials, it can withstand
gas pressures above 10KPa, and when the equipment is actually working, the pressure in the gas box of the fermentation room is within
4KPa to 5KPa. (When it exceeds 5KPa, it will be automatically eliminated from the discharge port). Therefore, users do not need to worry
about the danger of high pressure and explosion like natural gas, coal gas, and liquefied gas. On the other hand, because the fermentation
tank of this equipment is a soft, the depth has the characteristics of arbitrary (generally the depth is controlled between 0.6 and 1.2 meters),
it is not necessary to clean the tank, large discharge and repair the fermentation tank. People enter the tank to perform operations,
so it will not cause methane poisoning.
7. Sanitation and environmental protection: Because the product itself is a purification equipment for treating domestic waste, and its
entire fermentation process is carried out in a completely sealed state, without any pollution to the surrounding environment; when the
equipment is working normally, it can be automatically removed at any time The biogas slurry flowing out of the liquid drain is in full
compliance with the national discharge standards. The purified biogas slurry can be used to grow vegetables, water various crops
and other plants, and can also be used to raise pigs.
8. It is easy to use and maintain, easy to be mastered by ordinary people, and easy to popularize: you don't need much professional
knowledge, you can see it at a glance, and you can learn it with a general elementary school education. In the unlikely event that the
equipment is damaged by sharps or man-made destruction, users do not need to find dealers and manufacturers, and can repair and
troubleshoot by themselves. Wipe the damaged area with a clean cloth, and paste the damaged area with a piece of the same material
as the pool body (use PVC adhesive glue).
9. Easy to industrialized production and commercial operation: Because the main parts (biogas fermentation bag, biogas storage bag)
are made of plastic materials, it is easy to carry out industrial prefabrication production and folding packaging for commercial operation
(a set of 6 to 8 volumes) The packaged volume of equipment of cubic meters for 4 to 6 people shall not exceed 0 or 2 cubic meters,
and the gross weight shall not exceed 20-30 kg).
10. The complete set of equipment of this technology is serialized and can also be customized: it can be selected according to the amount
of domestic waste or fermentation raw materials of different users, and the size can also be customized. It can make 2m3, 3m3, 4m3, 5m3,
6m3, 8m3, 10m3 to 1000m3 and other biogas digesters.
