Current, China is carrying out the new socialist countryside construction comprehensively, and the fast development of livestock and poultry breeding industry; promoting agricultural restructuring; when increasing the agricultural income, the rural area pollution of area source that causes is aggravation day by day also, and it is outstanding further with the dual contradiction of environment protection to develop the economy.Exploitation " green energy resource " has become the important means that industrialized country in the world today increases income and decreases expenditure, turns harm into good and protects environment.In recent years, the feces of livestock and poultry anaerobically fermenting is produced the effective solution livestock and poultry cultivation of developing into of biogas technology and is polluted, and the exploitation clean energy provides technical support.The present flow lifting type anaerobism solid reactor that adopts; generally by tank body; pressure protector; the opening for feed pipe; the slag-drip opening pipe; liquid outlet tube; compositions such as gas outlet tube; when handling the livestock and poultry feces of high solid content; have the incomparable advantages of other reactors such as up-flow anaerobic sludge blanket; but in the practical application of large-sized biogas engineering, there are deadly defects such as crust; particularly keep with the marsh gas power generation waste heat in the biogas engineering of flow lifting type anaerobism solid reactor temperature of reaction at extremely frigid zones, the aerogenesis stability of flow lifting type anaerobism solid reactor and factor of created gase are directly connected to the continuity and the economy of biogas engineering operation.For this reason, exploitation efficient stable novel flow lifting type anaerobism solid reactor, just particularly important to solve the disadvantage that traditional flow lifting type anaerobism solid reactor exists.

The utility model content

The technical problems to be solved in the utility model is to avoid flow lifting type anaerobism solid reactor that the liquid level crust takes place when handling livestock and poultry feces product biogas, and guarantee that reactor temperature is evenly constant, improve the gas producing efficiency and the aerogenesis stability of flow lifting type anaerobism solid reactor, a kind of flow lifting type anaerobism solid reactor that is applicable to the large-sized biogas engineering is provided.

In order to solve the problems of the technologies described above, the utility model is made up of tank body, stirring broken shell assembly, pressure protector, opening for feed pipe, slag-drip opening pipe, liquid outlet tube, gas outlet tube and coil pack; Described tank body is the closed circular tubular, comprises tank deck, cylindrical shell, jar end; Tank deck is flat cover shape, half elliptic, half dish or semisphere; The central axis of described stirring broken shell assembly and coil pack and tank body central axes; Stir the broken shell assembly and comprise actuating unit, transmission shaft, sealing member, peeler, impeller; Described actuating unit is positioned at outside the tank deck, and links to each other with tank deck; Described transmission shaft links to each other with actuating unit and drives peeler and wheel rotation; Described sealing member is positioned at transmission shaft and passes through the tank deck place; Described peeler is connected on the transmission shaft, and is positioned at material cavity and near tank body feed liquid face; Described impeller is connected on the transmission shaft, and is positioned at the tank body bottom; Described pressure protector communicates with air chamber in the tank body, and is positioned at the tank deck place; Described opening for feed pipe links to each other with cylindrical shell, and is positioned at the cylindrical shell bottom; Described liquid outlet tube links to each other with cylindrical shell, and is positioned at cylindrical shell top, and jar inner opening that divides is lower than a jar outside part opening; Described gas outlet tube links to each other with tank deck; Described coil pack is made up of coil pipe and support, and cylindrical shell is passed through in the outlet of coil pipe import and coil pipe and tank body is interlinked to the outside.

The utility model is owing to adopt stirring broken shell assembly and coil pack, make operation simpler, handle feces of livestock and poultry class dirt and be difficult for crust, temperature of reaction is evenly constant, stable and reliable operation, and investment and working cost are lower, have advantages such as the load of processing is high, TS concentration is big, hydraulic detention time is short simultaneously, the solid content of handling feces of livestock and poultry class dirt can reach 8～15%, and the COD clearance can reach 60～80%, produces the biogas rate and can reach 1.5～3m ³/ m ³D.
