Intelligent cabin type aerobic composting device

Abstract

The invention discloses an intelligent cabin type aerobic composting device. The intelligent cabin type aerobic composting device comprises a fermentation cabin, a ventilation device and a real-time on-line monitoring device; the intelligent cabin type aerobic composting device is characterized in that a fermentation cabin body is a PVC (Poly Vinyl Chloride) double-layer cylinder, a temperature feeler lever, an oxygen feeler lever and a vent pipe are arranged at the top of the fermentation cabin, a thermal insulation layer is formed between an inner side wall and an outer side wall by hot air flows, a tail gas pipe is arranged at the side wall of the fermentation cabin, a buffer layer, a flow-guiding folded plate, an air inlet hole and a water draining pipe are arranged at the bottom of the fermentation cabin, the ventilation device comprises an air pump, a flow meter, an electromagnetic valve and an air pipe, the air pipe is connected with the air inlet hole, the on-line monitoring device comprises temperature, oxygen, tail gas (such as CO2, NH3 and H2S) monitors and flow meters. According to an aerobic composting device, a compost body can be quickly warmed up by a thermal insulation layer, the high temperature is continuously kept, air is fully and uniformly distributed by the buffer layer and the flow guiding plate, and the real time storage of continuous data can be realized by the on-line temperature, oxygen and tail gas monitors.

Description

technical field [0001] The invention relates to a stabilized and harmless composting technology for organic solid waste, in particular to a bin-type sludge aerobic composting device. Background technique [0002] With the acceleration of urbanization, the amount of urban sewage treatment has increased year by year, and the sludge production in sewage has also risen sharply. The composition of municipal sludge is complex. In addition to high moisture content and perishability, it also contains pathogenic bacteria, parasite eggs and toxic substances, and is accompanied by stench. If it enters the environment without proper treatment, it will directly pose a threat to the atmosphere, water bodies and human health. Municipal sludge is rich in organic matter and nutrients needed for plant growth and reproduction such as nitrogen, phosphorus, and potassium. Composted urban sludge can be used to produce organic fertilizers, or to improve soil, increase sealing fertility, and effec...

Problems solved by technology

Among them, the vertical fermentation bin has a large processing capacity and occupies a small area, but it is easy to cause uneven mixing of materials, resulting in unsatisfactory partial fermentation results; the drum type fermentation bin has the advantages of small footprint, flexible operation, and low energy consumption, but its fermentation bin The cross-sectional area of ​​the bottom is large, and the lack of buffer layer to homogenize the ventilation airflow makes it easy to compact the material and even cause partial anaerobic
