Efficient biogas residue aerobic composting reactor

Abstract

The invention discloses an efficient biogas residue aerobic composting reactor, and belongs to the technical field of aerobic composting reactors. The drum-type composting reactor comprises a reactor outer shell and a drum-type composting reactor body, the reactor outer shell is provided with an oxygen supply assembly, an odor collection assembly and a heat preservation assembly, the drum-type composting reactor body is located in an inner cavity of the reactor outer shell, and the axis of the drum-type composting reactor body is parallel to the horizontal plane. By adopting an efficient aerobic composting technology, the temperature of a compost body can be quickly raised, the decomposition of organic matters is accelerated, pathogenic microorganisms are effectively killed, the fertilizer efficiency of a compost product is improved, and a high-quality organic fertilizer product is produced.

Description

technical field [0001] The invention relates to a high-efficiency biogas residue aerobic composting reactor, which belongs to the technical field of aerobic composting reactors. Background technique [0002] Most of the domestic kitchen organic waste with high solid content adopts the main process of anaerobic digestion, and the yield of biogas residue after the pretreated kitchen waste enters the anaerobic fermentation is about 5~10%. Biogas residue is rich in organic matter, nitrogen, phosphorus, potassium and other nutrients and humus, and is a good source of fertilizer. However, due to the presence of pathogenic microorganisms, odor, and high moisture content in biogas residue, it is not suitable for direct land use. At present, aerobic composting is used to make organic fertilizers. Aerobic composting can kill pathogenic microorganisms, remove odors, reduce the moisture content of biogas residues, and enrich the nutrients in biogas residues, so as to achieve the purpose...
