Large-scale livestock breeding anaerobic reaction tank

Abstract

The invention discloses an efficient anaerobic reaction tank for large-scale raising of livestock. A central pipeline is arranged at the center of a tank body of the anaerobic reaction tank; a water distribution pipeline is fixedly arranged at the bottom of the central pipeline through a fixed support and is composed of six branch water distribution pipelines; a reflecting cone is arranged below the end part of each branch water distribution pipeline; a reducing pipe is arranged on a position where the central pipeline is in contact with the top of the anaerobic reaction tank; a water inlet pipeline is arranged at the side of the upper end of the central pipeline and is communicated with the six branch water distribution pipelines through the central pipeline; the tank body of the anaerobic reaction tank is provided with an exhaust pipeline at the top end and a drainage pipeline at the side; the top end of the exhaust pipeline is lower than the water inlet pipeline; and the top end of the drainage pipeline is lower than the top end of the exhaust pipeline. According to the efficient anaerobic reaction tank, waste sewage can be sufficiently subjected to anaerobic fermentation reaction by virtue of the water pressure obtained after the reducing pipe is reduced, the self gravity of the waste sewage and the height difference of the central pipeline, so that gas and sewage are effectively separated, and the yield of biogas is increased.

Description

Technical field: [0001] The invention relates to an anaerobic reaction device for breeding enterprises, in particular to an anaerobic reaction tank for large-scale breeding of poultry and livestock. Background technique: [0002] Large-scale specialized pig raising enterprises all have manure treatment biogas projects. Anaerobic digestion technology is generally used to treat a large number of pigs’ wastewater. After sedimentation, the wastewater is transported to an anaerobic reactor for treatment. The biogas can be used for power generation, and the generated biogas slurry can be used for farmland irrigation after aerobic treatment, thus realizing the resourceful, harmless and ecological reuse of waste water from pig farms. However, in the prior art, the upper end of one side of the anaerobic reactor is provided with a water inlet pipe, and the other side is provided with a drainage pipe, and the sewage is discharged quickly in the anaerobic reactor, and the gas and pollut...
