Aerobic composting device of mixed organic solid waste in villages and small towns

Abstract

The invention relates to an aerobic composting device of mixed organic solid waste in villages and small towns. The device comprises a reaction chamber body, a feeding and discharging system, pile turning ventilation devices a heat supply and insulation system, a deodorization system, a percolate treatment system and an intelligent detection system, wherein the pile turning ventilation device comprise ventilation pipes, electric mixing propellers and motors connected with the top ends of the ventilation pipes; the ventilation pipes and the electric mixing propellers are arranged in a main chamber body; the electric mixing propellers comprise the ventilation pipes and paddles arranged at the peripheries of the ventilation pipes; the ventilation pipes comprise inner layers, outer layers andfilter layers detachably arranged between the inner layers and the outer layers; two rows of air vents are formed in length directions of the ventilation pipes and distributed upwards and downwards alternately; a housing of the main chamber body is provided with an internal wall, a heat supply water pipe, a heat insulation layer and an external wall sequentially from inside out; and the heat supply water pipe surrounds the main chamber body. The device is uniform in ventilation, high in composting efficiency, perfect in automation system and high in intelligence, and has important significancein an aspect of the treatment of the mixed organic waste in the villages and the small towns.

Description

technical field [0001] The invention belongs to the field of waste devices, in particular to an aerobic composting device for mixed organic solid waste in villages and towns. Background technique [0002] In recent years, in the development of national urban-rural integration, the economic level of villages and towns has continuously stepped up to a new level. At the same time, the problem of mixed organic waste pollution in villages and towns has attracted more and more attention. [0003] At present, the treatment methods of mixed organic waste in villages and towns mainly include incineration, landfill, solidification and composting. At present, the most widely used is simple landfill treatment and incineration, which greatly endangers the environment of villages and towns. Since mixed organic waste is rich in organic matter, if it can be processed as a resource, it can not only promote the recycling of resources, but also reduce environmental pollution. Therefore, compo...

Problems solved by technology

[0004] At present, most of the aerobic composting technologies for village and town waste are aerobic static composting or aerobic dynamic composting. Among them, the agitation and ventilation of the device used in aerobic dynamic composting are two separate components, which not only increase the internal use volume and Construction cost, and it is easy to anaerobic fermentation due to insufficient oxygen, destroying the original microbial community
