Fermentation and air distribution device for aerobic composting of organic solid waste

Abstract

The invention discloses a fermentation and air distribution device for the aerobic composting of organic solid waste, which is provided with an automation control system and comprises a main air distribution channel and two rows of branch air distribution channels, wherein the main air distribution channel is arranged in the middle of a fermentation tank and is parallel to the wall of the fermentation tank; the two rows of branch air distribution channels are uniformly distributed at both sides of the main air distribution channel and are communicated with the main air distribution channel; and the main air distribution channel and each branch air distribution channel are respectively provided with a cover board with a plurality of air vents. In the overall fermentation process, the fermentation and air distribution device for aerobic composting does not need to be manually operated, can carry out enforced ventilation on the leavening, reduces the overturning frequency, reduces the odor emission in the treating process and lowers the energy consumption and production cost.

Description

technical field [0001] The invention relates to an air distribution device, in particular to an aerobic composting device for organic solid waste [0002] Yeast cloth gas device. Background technique [0003] In the prior art, in the process of composting organic solid waste, the fermentation process requires aeration, mainly turning over aeration and forced aeration, and forced aeration can shorten the fermentation time and improve efficiency. At present, there are two main types of air distribution methods used in forced ventilation. Firstly, the perforated metal or other material pipes are inserted or pre-embedded into the pile, and the pipes are connected to the blower. During the operation of this kind of ventilation method, the ventilation holes will be blocked by organic materials, which will reduce the ventilation effect. And because the surface area of ​​the pipeline is small, the air distribution is uneven. Second, the air distribution method of the prefabricat...

Problems solved by technology

During the operation of this kind of ventilation method, the ventilation holes will be blocked by organic materials, which will reduce the ventilation effect.

And due to the small surface area of ​​the pipe, the air distribution is uneven

Second, the air distribution method of the prefabricated air distribution channel on the floor of the fermentation tank. When this type of air distribution channel is in use, due to the organic material falling into the pipeline, the pipeline will be completely blocked for a long time, resulting in uneven local ventilation, and Difficult to clean, reduced ventilation effect

The above two types of gas distribution methods are due to the poor ventilation of the pipeline, which reduces the treatment effect
