Composting reactor

Abstract

The invention relates to a composting reactor for organic solid waste composting production, which comprises a reactor frame, a closed reaction chamber, a charging device, an aeration and stirring system and a biological filter tank, wherein the closed reaction chamber is installed on the reactor frame and provided with a feed port; the charging device is positioned on one side of the closed reaction chamber, arranged relative to the feed port, and used for delivering an organic solid waste raw material into the closed reaction chamber; the aeration and stirring system is partially installed in the closed reaction chamber, and comprises a stirring device and an aerator which are connected with each other; the stirring device is used for slowly and intermittently stirring the organic solid waste raw material which is delivered into the closed reaction chamber; the aerator is used for delivering fresh air to the inside of the organic solid waste to accelerate the aerobic fermentation; and the biological filter tank is communicated with the closed reaction chamber through an induced draft fan, and used for further treating tail gas generated in the organic solid waste aerobic fermentation process. The composting reactor has the advantages of compact structure, high efficiency, energy saving, no odor pollution in the treatment process, and high automation degree.

Description

technical field [0001] The invention relates to organic solid waste treatment and utilization technology, in particular to a vertical dynamic composting reactor suitable for organic solid waste composting production. Background technique [0002] In recent years, organic solid waste such as livestock and poultry manure has caused heavy environmental pressure. On the one hand, the loss rate of livestock and poultry manure into the water body is as high as 25-30%, and the loss of nitrogen and phosphorus and the total amount of COD emissions have exceeded chemical fertilizers. On the one hand, soil compaction caused by the reduction of organic matter and excessive application of chemical fertilizers is becoming more and more serious. The development of efficient and practical composting treatment equipment is conducive to promoting the resource utilization of solid waste. The use of mechanical equipment to regularly turn over and aerate materials can effectively accelerate ferm...
