Abstract

The invention discloses a double-ring anaerobic reaction tank for treating restaurant garbage and kitchen waste. The double-ring anaerobic reaction tank comprises a tank body and a stirring device, wherein the tank body comprises an inner reaction tank and an outer reaction tank, the outer side of the inner reaction tank is sleeved with the outer reaction tank, the interior of the outer reaction tank is a first reaction zone, and the interior of the inner reaction tank is a second reaction zone; the stirring device is arranged in the tank body; and the stirring device comprises rotating assemblies, a lifting assembly and stirrer assemblies, each rotating assembly comprises a guide rail, the guide rails are arranged in the tank body and parallel to the axis of the tank body, the stirrer assemblies are slidably arranged on the guide rails, the guide rails can drive the stirrer assemblies to rotate, and the lifting assembly can drive the stirrer assemblies to move up and down on the guiderails. According to the anaerobic reaction tank, the occupied area of anaerobic reaction equipment is reduced through the two tank bodies which are sleeved together, slurry reacts more completely through the stirring device, and the overall efficiency of anaerobic reaction is improved through the improvement of the two aspects.

Description

technical field [0001] The invention relates to the technical field of garbage treatment equipment, in particular to a double-loop anaerobic reaction tank for treating kitchen and kitchen waste. Background technique [0002] When treating kitchen waste and kitchen waste, anaerobic treatment of the slurry is usually required. In the prior art, a first-stage anaerobic reaction is usually used, and a fully mixed anaerobic reactor is used for treatment. [0003] When anaerobic treatment is carried out through a fully mixed anaerobic reactor, since the fully mixed anaerobic reactor needs to be equipped with a floor-standing gas cabinet separately, the entire anaerobic system occupies a large area, which is not conducive to the production of the enterprise. [0004] At the same time, the slurry usually needs to be continuously stirred in the anaerobic reactor, but in the prior art, the top stirring method is generally used, and the stirring device is driven by power to rotate to d...
