Problems solved by technology

However, in the general aerobic fermentation process, the fermentation materials need to be stacked flat, which not only takes up a large area of ​​space, but also reduces the effect of fermentation if the accumulation is too thick. At the same time, the fermentation process needs to be turned frequently to increase the contact between the materials and oxygen In the process of turning over materials, it not only consumes a lot of manpower and material resources, but also reduces the amount of contact between materials and oxygen due to the excessive accumulation of materials, resulting in poor fermentation effect

Abstract

The invention relates to the technical field of sludge treatment, in particular to a device and process for preparing an organic fertilizer by aerobic fermentation of sludge through high-pressure thermal cracking. The device comprises a fermentation box, a plurality of high-pressure fans are arranged on the left side wall and the right side wall of the fermentation box, a plurality of rightward conveying belts and a plurality of leftward conveying belts are sequentially arranged in the fermentation box from top to bottom in a staggered mode, and a rightward turning and stirring device is arranged in the middle of the top face of each rightward conveying belt and comprises a rotating roller; a plurality of long-strip-shaped tipping buckets are regularly welded and fixed to the outer side wall of the rotating roller in the clockwise direction, and a leftward turning and stirring device is arranged in the middle of the top face of the leftward conveying belt. According to the device designed by the invention, the occupied area can be saved, the contact amount of materials and oxygen is increased, the fermentation effect is improved, meanwhile, a continuous material fermentation process can be realized, and manpower and material resources are saved; according to the process in the design, the fermentation speed can be increased, the fermentation effect is improved, the processing cost is reduced, and the overall quality of an organic fertilizer finished product is further improved.

Description

technical field [0001] The invention relates to the technical field of sludge treatment, in particular to high-pressure pyrolysis sludge aerobic fermentation organic fertilizer production equipment and technology. Background technique [0002] After the sludge is harmlessly treated, it can produce organic fertilizer through aerobic fermentation to realize resource recovery and reuse. However, in the general aerobic fermentation process, the fermentation materials need to be stacked flat, which not only takes up a large area of ​​space, but also reduces the effect of fermentation if the accumulation is too thick. At the same time, the fermentation process needs to be turned frequently to increase the contact between the materials and oxygen In the process of turning over materials, it not only consumes a lot of manpower and material resources, but also reduces the amount of contact between materials and oxygen due to the excessive accumulation of materials, resulting in poor ...
