NOVELTY - Producing methane using barometric disturbance stirring ultra high-efficient fermentation system, comprises pouring the fermentation raw material into a cylinder of primary fermentation system and secondary feed tube of secondary fermentation system, carrying out fermentation production of biogas in primary fermentation system and accumulation of biogas in and out of the side wall and adjacent of the cylinder and fermentation area formed between the air resistance plate, squeezing primary fermentation system pipeline to flow the slurry into a first aqueduct and a second aqueduct.    USE - The method is useful for producing methane using barometric disturbance stirring ultra high-efficient fermentation system (claimed).    DETAILED DESCRIPTION - Producing methane using barometric disturbance stirring ultra high-efficient fermentation system, comprises: (a) pouring the fermentation raw material into a cylinder of primary fermentation system and secondary feed tube of secondary fermentation system; (b) carrying out fermentation production of biogas in primary fermentation system and accumulation of biogas in and out of the side wall and adjacent of the cylinder and fermentation area formed between the air resistance plate or adjacent air resistance plate, squeezing primary fermentation system pipeline to flow the slurry into a first aqueduct and a second aqueduct, increasing the liquid level of the slurry in the first aqueduct and second aqueduct which eventually flows into the secondary fermentation pipeline; (c) carrying out fermentation production of biogas in secondary fermentation system and accumulation of biogas in the inlet/outlet pipe of side wall and adjacent of the cylinder and fermentation area formed between the air resistance plate or adjacent air resistance plate, squeezing primary fermentation system pipeline to flow the slurry into a feeding tube, a secondary discharge tube and a discharge tube of bio device, where the slurry has unidirectional flow from discharge tube of bio device into hydraulic pressure chamber, storing the biogas slurry in the hydraulic pressure chamber until slurry level reaches the lowest point; (d) passing the slurry stored in hydraulic pressure chamber into the fermentation pipeline via third aqueduct and a fourth aqueduct using primary fermentation storage biogas pipeline; (e) passing the slurry into primary fermentation pipeline using secondary fermentation storage biogas pipeline, then squeezing the primary fermentation pipeline into the secondary fermentation pipeline; and (f) repeating the process to generate methane utilizing biogas.
