Abstract

The invention relates to the technical field of organic solid waste treatment, in particular to a closed silo composting reactor. The closed silo composting reactor comprises a composting silo, a stirring device, a hydraulic drive device and a discharge screw conveyor, wherein a feed port and an exhaust port are formed in the top of the composting silo; a discharge port is formed in the bottom of the composting silo; the discharge screw conveyor corresponds to the discharge port; the stirring device is arranged in the composting silo; the hydraulic drive device drives the stirring device to rotate and stir. The composting silo adopts vertical closed design, has high effective volume and can increase fermentation temperature, so that the fermentation period is greatly shortened; the stirring device performs continuous dynamic stirring, thereby having stirring, mixing and loosening effects and avoiding material compaction; with the adoption of rotating aeration, effectiveness and uniformity of aeration are improved.

Description

technical field [0001] The invention relates to the technical field of organic solid waste treatment, in particular to a closed silo composting reactor. Background technique [0002] Composting technology is the key technology to realize the harmless treatment and resource utilization of organic solid waste. The traditional composting forms mainly include strip stacking and horizontal trough systems. Hydrogen sulfide and other odors pollute the environment. In order to overcome the shortcomings of traditional composting systems, closed composting systems have also been developed at home and abroad in recent years. This system has high system integration, good airtightness, fast composting speed, and automatic control. The characteristics of high degree of composting, low input cost and fast construction period represent the future development direction of composting technology. [0003] At present, closed composting systems include silo-type composting reactors, tower-type ...
