Embodiment 1
[0025] The dry fermentation automatic circulation system of the present embodiment is as Figure 1 to Figure 6 As shown, the basic structure is: a fermentation storehouse 4 with a feed port at the top of the feed end and a discharge port at the bottom of the discharge end, and a biogas slurry collection tank 26 communicating with it through a drain grid 25 below the fermentation storehouse 4 . Two rows of spray pipes parallel to each other with nozzles 23 arranged at intervals are arranged above the fermentation tank 4 , and the biogas slurry collection pool 26 communicates with the spray pipes through a pipeline 24 passing through a biogas slurry circulation pump 27 . The bottom of the fermentation storehouse 4 is equipped with two rows of screw conveyors 7 parallel to each other and controllable in the direction of rotation extending from the feed end to the discharge end. A feed hopper 2 provided with a star discharger 10 at the bottom is installed on the feed inlet, and t...

The invention relates to an anaerobic dry-process fermentation continuous automatic charging and discharging system, as well as a usage method thereof, belonging to the technical field of biomass utilization. The system comprises a fermentation pool, a charging opening is formed in the top of a charging end of the fermentation pool, a discharging opening is formed in the bottom of a discharging end of the fermentation pool, and a biogas slurry collecting tank communicated with the fermentation tank through a drain gate plate is arranged below the fermentation pool; a spray pipe on which nozzles are distributed at intervals is arranged at the upper part inside the fermentation pool, the biogas slurry collecting tank is communicated with the spray pipe through a pipeline of a biogas slurry circulating pump; a spiral conveyor extending to the discharging end from the charging end is arranged at the bottom of the fermentation pool; a feed hopper the bottom of which is provided with a star type discharging device is arranged at the charging opening and is positioned below the output end of a charging conveyor; an openable discharging opening baffle is arranged at the discharging opening and positioned above the lower end of a discharging conveyor. The anaerobic dry-process fermentation continuous automatic charging and discharging system realizes the automatic continuous charging and discharging, thereby greatly reducing the construction and operation cost of dry fermentation engineering and improving the charging and discharging operation efficiency of biogas engineering.
Description
technical field [0001] The invention relates to a dry fermentation device, in particular to an anaerobic dry fermentation continuous automatic feeding and discharging system, and also relates to its use method, which belongs to the technical field of biomass utilization. Background technique [0002] Biogas dry anaerobic fermentation has been very popular, but so far, the fermentation raw materials are in a static state of no flow during the dry fermentation process, so the mass and heat transfer effect is poor, the fermentation is uneven and incomplete, and its feed and output The material operation is very difficult, especially the design and sealing of the material inlet and outlet gate of the dry fermentation device has serious defects, and only intermittent fermentation can be carried out. There are low efficiency, high strength, harsh operating environment and potential safety hazards in the loading and unloading operation of the loader And other issues. The current b...
