The 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. The Group is the only manufacturer in China that produces red mud biogas digester materials and downstream biogas digesters and final products for sewage treatment.
I.The high-density polymer composite materials used in soft biogas digesters are produced in strict accordance with the quality system. This product has the following features:
a. Long service life, normal use can reach more than 15 years.
b. High temperature resistance (50 degrees), high cold resistance (-20 degrees), acid and alkali resistance, lightning protection, shock resistance, tear resistance, flame retardant.
c. The success rate of pool building is 100%.
d. The air outlet rate is high, and there will be no air leakage after the pool is built.
e. High safety, no need to clean the pool, no animal danger
II.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.
III.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.
