Piping system for a biogas plant for generating gas from a substrate, comprises a decomposition tube for decomposition reaction section for the decomposition of the substrate, and a methane-forming tube for methane-forming reaction section
The piping system comprises a decomposition tube for a decomposition reaction section (ZRA) for the decomposition of a substrate, and a methane-forming tube (19) for a methane-forming reaction section (MRA) for the formation of the methane from the decomposed substrate in the decomposition reaction section. The decomposition tube and/or the methane-forming tube are part of a predominant continuous flow path. The methane-forming tube is spatially separated from the decomposition tube. The decomposition tube and the methane-forming tube are made of glass-fiber reinforced plastic. The piping system comprises a decomposition tube for a decomposition reaction section (ZRA) for the decomposition of a substrate, and a methane-forming tube (19) for a methane-forming reaction section (MRA) for the formation of the methane from the decomposed substrate in the decomposition reaction section. The decomposition tube and/or the methane-forming tube are part of a predominant continuous flow path. The methane-forming tube is spatially separated from the decomposition tube. The decomposition tube and the methane-forming tube are made of glass-fiber reinforced plastic and are formed in a cylindrical manner. The flow path is formed from flow sections with a gradient of less than 10[deg] . The piping system has a backflow prevention unit, and an ultrasonic crushing unit. A cylindrical silo tube (11) is provided for a silage section and is upstreamly arranged to the decomposition tube as part of the flow path. The ultrasonic crushing unit is upstreamly arranged to the methane-forming tube in the silage section and/or in the decomposition reaction section. A supply device is upstreamly arranged to the silo tube for supplying crushed raw materials, and is formed by a conveyor tube (4) with a mixing section for conveying the raw material in the direction of a pump outlet of the supply device and a rear guiding tube arranged between the mixing section and the pump outlet for reguiding the raw material to the mixing section. A solid pump (10) is provided at the pump outlet of the supplying device for defined passage of the raw material into the silage section. A gas separating unit is provided at the end of the decomposition reaction section for partial gas separation and is provided in the form a rising tube. A methane-forming addition unit is provided between the decomposition reaction section and the methane-forming reaction section for defined addition of methane-producing bacteria in form of liquid manure. A temperature-rising unit is provided for increasing the temperature of the substrate in countercurrent by a heating pump. A gas separating section is dowstreamly arranged to the methane-forming reaction section for pressure-controlled gas separation. The gas separated from the substrate in the gas separation section is partially reguidable to the substrate in the methane-forming reaction section by a bacteria-enrichment tube (37).
