Embodiment

[0023] Example: such as figure 1 As shown, a high-efficiency aerobic fermentation device for organic waste includes a storage bin 1, a material crushing and mixing equipment 2, a fermentation reaction bin 3, an exhaust gas treatment device 5 and a PLC controller 4; Shaped or rectangular bin body, the top is equipped with a material inlet, and the bottom is equipped with a material outlet. The material inlet is large and the material outlet is conical. The material outlet of the storage bin 1 is crushed and mixed with the material through a belt and a pump. The feed port of the equipment 2 is connected, and the material is transported to the material mixing equipment 2 for subsequent processing. The material crushing and mixing equipment 2 of this embodiment uses a biaxial shearing crusher to crush the waste to the required size, and at the same time make the material fully The degree of mixing and crushing shall be adjusted according to the actual design requirements; the disc...

Abstract

The invention discloses a high-efficiency aerobic fermentation device of organic wastes. The high-efficiency aerobic fermentation device is characterized in that a storage bin is connected with material crushing and mixing equipment which is connected with a fermentation reaction bin; the fermentation reaction bin is internally provided with a stirring device, microbial strains are placed in the fermentation reaction bin which is connected with a blower; the fermentation reaction bin is internally provided with a temperature sensor and an oxygen concentration sensor; a finished-product output hole at the bottom part of the fermentation reaction bin is connected with a finished-product stack and the storage bin; a waste-gas exhausting hole at the top part of the fermentation reaction bin is connected with a waste-gas treating device; and a PLC controls the whole device. The high-efficiency aerobic fermentation device disclosed by the invention has the advantages that the occupied area is small, the fermentation period is short, the mechanization degree is high, tail gas has no secondary pollution, and a finished product meets the requirements on reduction, harmlessness, stabilization and recycling and reaches national standards in China.

Description

technical field [0001] The invention belongs to the field of urban organic waste treatment, and in particular relates to a high-efficiency aerobic fermentation device for urban organic waste such as urban domestic waste, kitchen waste, sewage plant sludge and intensive livestock and poultry manure. Background technique [0002] With the rapid development of my country's economy and the acceleration of urbanization, cities have produced a large amount of organic waste, such as domestic waste, kitchen waste, sludge from sewage plants and intensive livestock manure, etc. Stable and perishable, and contains a variety of pathogenic microorganisms, parasite eggs, etc. [0003] Proper treatment must be carried out to avoid secondary pollution. The main treatment methods are incineration, landfill, aerobic fermentation and so on. [0004] Because landfilling requires a large area of ​​land, [0005] The leachate contains toxic substances and is difficult to deal with; the investmen...
