Abstract

The invention relates to the technical field of treatment of organic solid wastes, in particular to a compensation type aeration turning-free aerobic fermentation device. The device comprises an aeration device and a stirring device, wherein the aeration device is arranged in a fermentation barrel and comprises two aeration pipes with the same pipe specifications; the two aeration pipes are embedded mutually in a shape of a vortex line; a plurality of aeration holes are formed in each aeration pipe; the corresponding aeration holes and each aeration pipe are downwards equidistantly arranged ina staggered manner at an angle of 120 degrees; the stirring device comprises a stirring shaft, stirring blades and a plurality of blade supporting rods; the stirring blades spirally rises along the stirring shaft; and the stirring blades are fixedly connected to the stirring shaft through the blade supporting rods. A compensation type pipe distribution mode is adopted, thus, aeration is uniform,anaerobic fermentation regions are reduced, aerobic fermentation of organic solid wastes is fully, the fermentation effect is improved, by the internal stirring device, an effect of turning operationcan be achieved, and materials can be fully mixed and are stirred uniformly.

Description

technical field [0001] The invention relates to the technical field of organic solid waste treatment, in particular to a compensation type aeration-free aerobic fermentation device. Background technique [0002] With the rapid development of my country's economy and society and the continuous acceleration of urbanization, more and more industrial, agricultural and domestic wastes are produced. Among them, the amount of organic solid waste (mainly sludge, livestock and poultry manure and kitchen waste) is very large. According to estimates, my country produces 30-40 million tons of municipal sludge with a moisture content of about 80% and 40 million tons of waste per year. In addition, my country produces about 3.8 billion tons of livestock and poultry manure and 60 million tons of kitchen waste every year. The output of municipal sludge has maintained a sustained and rapid growth. It is estimated that by 2020, the output of municipal sludge in my country will reach 60-90 mil...
