Abstract
Disclosed is a dry anaerobic digestion device which is vertically moved. The anaerobic digestion device comprises a tank body of a vertical anaerobic digestion tank; the top of the anaerobic digestion tank is provided with a biogas outlet, a relief valve connection and an inspection manhole and the bottom is a taper bucket. The anaerobic digestion device is characterized in that the lower opening of the taper bucket is communicated with the inlet of a control valve, while the outlet of the control valve is communicated with the upper opening of a feeding recycle pump through a pipeline; the upper opening of the feeding recycle pump is communicated with the lower opening of a feed hopper through a valve; the lower opening of the feeding recycle pump is communicated with the inlets of 2-10 vertical feeding pipes in the anaerobic digestion tank through the pipeline and the valve; the outlet of each feeding pipe is arranged close to the top of the tank body of the anaerobic digestion tank; the bottom of the tank body of the anaerobic digestion tank is provided with a steadier. When the utility model is used to treat materials, the solid content ratio can reach 15 to 40 percent. The utility model has the advantages of simple structure, free maintenance, and simple and convenient operation management; has no internal stirrer and moving parts; the volume biogas production can reach 5 to 20 square meters per cubic meter; and the utility model produces no liquid waste, no solid disposition and is sealed without releasing waste gas.
Description
Technical field
The utility model relates to a kind of device of organic waste anaerobic digestion, particularly relates to a kind of device of organic waste dry-type anaerobic digestion of vertical operation.
Background technology
The organism refuse comprises processing of farm products refuse, feces of livestock and poultry, domestic waste, municipal sludge etc., these refuses contain a large amount of organic compositions, be good anaerobic fermentation raw material, can be converted into biogas, and the natural pond slag that produces is good organic fertilizer as utilization of regenerative energy.The anaerobic digestion device that adopts is the wet type fermentation of solid content at 4-10% mostly at present, be characterized in needing the bigger reactor of volume usually, take up an area of big owing to handle organism refuse hourly water consumption height, also need to consume more energy, a large amount of natural ponds liquid of fermentation back generation also needs to handle in addition.The investment of wet type fermentation unit is big, occupation of land is many, energy consumption is high, the unit volume factor of created gase is low.
Summary of the invention
The purpose of this utility model provides a kind of dry anaerobic digestion device of vertical operation, and it can directly handle organic waste, and it is easy to have an operation, and the characteristics of reduced investment can solve the above-mentioned weak point of prior art.
A kind of dry anaerobic digestion device of vertical operation, vertical type anaerobic digester tank body is arranged, its top has biogas to efflux mouth, relief valve connection and inspection manhole, the bottom is the taper bucket, the end opening that it is characterized in that the taper bucket is communicated with the inlet of by-pass valve control, the outlet of by-pass valve control is communicated with the suitable for reading of feed cycle pump by pipeline, the suitable for reading of feed cycle pump also is communicated with the end opening of hopper by valve, the end opening of feed cycle pump passes through pipeline, the inlet of the 2-10 root feed pipe that stands vertically in valve and the anaerobic digestion tank is communicated with, all near the top of anaerobic digestion tank, support is arranged at the bottom of anaerobic digestion tank in the outlet of each feed pipe.
During the utility model material handling, solid content can reach 15-40%; Simple in structure, there are not inner Mixing Machine and movable part, non-maintaining, operational administrative is easy; The anaerobic digestor volume yield rate can reach 5-20m
3/ m
3No waste water produces, no deposition of solids, the airtight waste gas that do not discharge.
