biogas generator

biogas generator by bolted tank

Biogas generator by bolted tank is the most widely used biogas generator at present, mainly because Bolted Steel Storage Tanks is built according to fast speed, with short construction period and is very corrosion-resistant and durable ，biogas generator is now built through the Bolted Steel Storage Tanks.

Steel plate rolling biogas fermentation tank is also known as the biogas generator.biogas generator applies the principle of metal plastic work hardening and thin shell structure, adopts screw, double folding, occlusion process and special rolling, occlusion, compression molding equipment to build biogas fermentation tank.

biogas generator by bolted tank made by this technology has the advantages of short construction period, steel saving, light deadweight, service life of more than 20 years and considerable ring tensile strength. But it needs special equipment to make, the steel plate material used is not the general specification on the market, and the construction volume should not be too large, the volume of a single pool generally does not exceed 5000m3.

biogas generator are usually made of galvanized or stainless steel-galvanized steel clad sheets of 495 mm wide and 2-4 mm thick. Theoretically speaking, the steel plate thickness of the tank can be smaller than 2 mm, but considering the structural stability, the material is generally not less than 2 mm. In view of the limitation of the mechanical occlusion tightness and compressive strength, the material is generally not more than 4 mm.

Because the material used in Lipper tank is less, the requirement of Lipper tank to the bottom plate foundation is far less than that of reinforced concrete tank to the bottom plate foundation. When pouring the base plate, a reserved groove with a width of 150 mm and a depth of 100 mm is left on the surface of the bottom plate according to the diameter of the tank to be made. A certain number of anchored stainless steel embedded parts are evenly placed in the groove according to the diameter of the groove. Concrete and asphalt, linoleum and other materials to seal the groove, and finally cover the stone concrete protective layer.

For corrosion protection, although the Lipper tank made of galvanized steel sheet has certain anticorrosive effect, the galvanized layer attached to the steel sheet surface is not enough to resist the corrosion of liquid and gas. Especially at the opening and the welding places of installation platform, railing and insulation fixture, the galvanized layer on the steel sheet surface is easy to be damaged. Therefore, anti-corrosion treatment is still necessary after the completion of the tank production and the qualification of the experiment. Similarly, the biogas fermentation tank using Lipu can make the insulation structure. The anticorrosive treatment method is the same as that of the steel plate welded fermenter.

Bolted Steel Storage Tanks

biogas generator of Bolted Steel Storage Tanks

biogas generator of Bolted Steel Storage Tanks is made of steel plate overlapping technology and bolts for fastening and installation. The tank body and the roof materials are all made of steel plate conforming to the national standards. The steel plate is processed in the factory for longitudinal and transverse overlapping, and the joint is sealed and assembled by the professional polymer sealant polysulfide glue. According to the different surface materials can be subdivided into: enamel assembly tank, thermal spraying assembly tank, electrophoretic paint assembly tank and so on.

Biogas, as the name suggests, is a gas in the marsh. It is often seen that in swamps, sewers or dung tanks, there are bubbles, if we strike a match, it can be ignited, this is the natural occurrence of biogas. From the point of view of scientific definition, biogas is a kind of combustible gas produced by microbial fermentation under the condition of isolating air (reducing condition) and at the appropriate temperature and pH value. Biogas is the two energy and renewable energy.

Biogas is a mixture of organic substances produced by microbial fermentation under anaerobic conditions. Biogas, as the name suggests, is the gas in the marsh. It is often seen that in swamps, sewers or dung tanks, there are bubbles, if we strike a match, it can be ignited, this is the natural occurrence of biogas. Because this gas was first discovered in the marsh, it is called biogas. Man and livestock excrement, straw, sewage and other organic matter in the closed biogas digester, fermented under anaerobic (no oxygen) conditions, is decomposed and transformed by a variety of biogas fermentation microorganisms, thereby producing biogas.

Biogas is a mixture of gases, which is similar to natural gas. In addition to direct combustion for cooking, drying agricultural and sideline products, heating, lighting and gas welding, biogas can also be used as fuel for internal combustion engines and chemical raw materials such as methanol, formalin and carbon tetrachloride. The liquid and sediment discharged after fermentation in a biogas plant are rich in nutrients and can be used as fertilizer and feed.
