Drum-type aerobic composting reactor

Abstract

The invention discloses a drum-type aerobic composting reactor which comprises a drum main body, a drum main shaft, a rack, a motor, a speed reducer and a transmission mechanism, wherein an inside liner at the inner side of the drum main body is divided into a plurality of mutually separated inside line compartments; each compartment is internally provided with an intake pipe, an exhaust pipe and a water outlet; pipe systems which are used for ventilation and drainage are arranged at two ends of the drum main body; through controlling valves on the intake pipes and the exhaust pipes, the ventilation direction of always pumping in from the lower side of stockpile in the drum and discharging from the upper side of the drum is realized; and meanwhile, through a design of backflow prevention in the compartments of the inside line of the drum, the moisture generated by the stockpile in the composting process is prevented from rotating along the drum to flow back to the stockpile. By using the design, the ventilation of the drum reactor is more uniform and sufficient and the property of the materials in the composting process is more uniform, so that the effect of the composting and the quality of the composting products are improved.

Description

technical field [0001] The invention relates to a reactor for aerobic composting of solid waste, in particular to a belt reactor for treating domestic sewage sludge Background technique [0002] Domestic sewage sludge aerobic composting can be divided into strip stacking, tank, reactor aerobic composting and so on according to the different storage methods in the composting process. In the reactor-type aerobic composting technology, according to the ventilation mode of the reactor, the stirring mode and the material storage mode of the reactor, it can be divided into a natural ventilation reactor, a forced ventilation static reactor, and a forced ventilation dynamic (stirring) reactor. and roller reactor technology. The drum reactor is one of the emerging aerobic composting reactors in recent years. Most of the existing roller reactors are horizontal rollers. [0003] In the process of aerobic composting, in order to ensure sufficient oxygen supply in the compost, it is n...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to overcome the deficiencies and deficiencies of the existing drum-type aerobic composting reactor, such as insufficient ventilation and oxygen supply, ventilation pipelines affecting the stirring and mixing of stacking materials, lack of anti-reflux design of leachate and condensed water, and provide a A drum-type aerobic composting reactor with directional ventilation and anti-reflux device
