Vertical dry-process anaerobic fermentation device

Abstract

The invention relates to an anaerobic fermentation treatment device, aiming to provide a vertical dry-process anaerobic fermentation device by using high-pressure marsh gases to be stirred and treating organic wastes in a rotary transversal-push type manner. The invention is characterized in that the device is composed of a vertical cylindrical tank body and a feeding pump, wherein the vertical cylindrical tank body comprises a complete mixing type reactor on the upper layer and a manipulator room on the lower layer; a partition wall is arranged in the reactor along the diametrical direction, and the wall ridges of the wall are connected with the side walls of the reactor; the side walls of the reactor at the two sides of the partition wall are provided with feed inlets and feed outlets with different heights; the bottom of the reactor is provided with a high pressure spraying nozzle; due to the partition wall, the fermenting materials move round a circle direction to from a horizontal plug flow movement after the organic wastes are pumped into the reactor; and the compressed marsh gases enter into the reactor by the spraying nozzle for stirring fermention of the materials. The invention has the advantages of reasonable structure, large unit volume, no mechanical equipments in the reactor, low cost, high treatment benefit, large gas generation rate, energy conservation, no environmental pollution and the like.

Description

technical field [0001] The invention belongs to the field of energy utilization and environmental protection, and relates to a device for anaerobic fermentation treatment, in particular to a vertical dry anaerobic fermentation device for organic waste. Background technique [0002] Organic waste, such as: agricultural waste, household waste in cities, animal manure and urine from animal husbandry, waste residue from the food industry, etc. Organic waste is the best raw material for anaerobic fermentation, which can be converted into alternative energy Material biogas, while biogas residue is also a good organic fertilizer. [0003] The anaerobic fermentation technology of organic waste is a biochemical reaction process in which organic waste degrades organic matter in the anaerobic biological bacteria derivation cycle, and finally produces biogas and biogas residue. At present, the commonly used anaerobic fermentation technology of organic waste is mainly two types: wet met...
