PVC tarpaulin for biogas digester

Using DER's unique red mud biogas digester material and advanced high-temperature welding technology, the red bag software biogas digester has the advantages of good air tightness, anti-aging, corrosion resistance, continuous gas production at low temperature, low cost, convenient installation, and safe use. Widely used in biogas digesters, household digesters, gas storage bags, etc.

I.The Advantage

1. The material is made of polymer PVC fabric coated biogas membrane material, which has strong air tightness.

2. The product is made by high-frequency heat-sealing, processed and produced at one time, and has the functions of anti-aging, flame-retardant, acid and alkali resistance, corrosion resistance, insect resistance, mildew resistance, frost resistance, sun exposure, lightning protection, and earthquake resistance. Scaling performance Well, not affected by the climate temperature difference.

3. Product commercial packaging, light weight, small size, easy to transport and carry. Easy to install, simple to operate, quick to start gas production, suitable for installation and use under different geological conditions, such as stone foundation, soil foundation, sand foundation, etc.

4. It is convenient to use and maintain, farmers can clean the slag on the surface without entering the pond, ensuring safety, and can move the place of use multiple times.

5. The cost is low. The cost of the biogas generator is one third of that of the concrete and FRP biogas digesters. It has a long service life, more than twice the average service life of an ordinary biogas digester.

II.How to use the soft digester?

Due to the difference in fabric thickness, material and finished product volume, the pressure it can withstand is not fixed, generally between 0.3kpa and 10kpa. To ensure safety and prolong the service life of the biogas bag, a safety exhaust valve should be installed to control the pressure within the rated range. The user can choose the product of the corresponding material and the safety exhaust valve according to the required rated air pressure.

1. FOR Biogas storage bag:

In view of the current situation of biogas development in my country, it is necessary to produce biogas storage bags. First, the pressure of biogas digesters currently built in various places is generally 10kPa. When gas is produced for a long time in summer, a large amount of biogas escapes from the water pressure room, overflow hole and safety valve, which cannot be fully utilized. Second, the gas chamber of the small household biogas tank is too small to maintain the gas supply pressure like a hydraulic biogas tank, so the sustainable use time is short. Therefore, in order to improve the utilization rate of biogas and prolong the continuous use time, Jinan Dongfanglong Technology Industrial Co., Ltd. has specially produced biogas storage bags after years of research and development. full use of purpose.

Then How to use the air bag?

(1) Choose a flat place to place it to prevent sharp objects and poultry damage.

(2) When using small bags under two cubic meters, press an appropriate amount of weight on the bag to ensure the use of air pressure. Larger biogas bags should be equipped with a biogas booster pump.

(3) Check the tightness by applying soapy water, and repair the air leak with PVC plastic adhesive.

2. For Soft biogas digester

The soft biogas digester is a biogas fermentation device mainly made of human and animal manure, sewage and other materials. It is suitable for family use. The specifications can be large or small, and various types of pools can be designed and manufactured according to user requirements.

Then How to use the soft digester?

(1) Basic conditions of biogas fermentation: strict anaerobic environment; appropriate amount of inoculum (sludge in biogas digester or activated sludge under septic pit, sludge in slaughterhouse sewer); appropriate amount of fermentation raw materials; high temperature; suitable PH value.

(2) The biogas raw materials, such as cow dung and pig manure, can be composted, and a small amount of quicklime can be added to adjust the pH. Generally, the compost is composted for 3 to 5 days. The accumulation and production conditions of anaerobic bacteria can be quickly formed by composting, and the biogas can be loaded into the biogas. After the bag can reach the peak gas production in the shortest time, it can be put into the soft biogas bag. Seal one end of the material port with a splint, and add 100~200 kg of sewage and biogas residue while adding biogas raw materials from the other material port. After filling, seal it with a splint, and push the biogas bag to mix the materials evenly. Generally, it takes 2 to 5 days. Gas can be used. If the gas produced at the beginning is not easy to burn due to the mixed gas, it must be discharged. Generally, it can be discharged 1~2 times before it can be used on fire. One feeding can be used for about six months, and when the gas production drops significantly, the material should be prepared in advance for retting. With the circulating biogas tank with inlet and outlet, the biogas material can enter and exit the gas for continuous gas production at any time.
