Abstract

The invention discloses a convenient gas distribution device for aerobic composting, and belongs to the field of aerobic composting fermentation. The provided gas distribution device solves the problems that in the prior art, the structure of a conventional gas distribution device for composting fermentation is complicated, the installation cost is large, the gas flow is poor, and the fermentationefficiency is low. The gas distribution device is provided with a plurality of gas distribution pipes; the walls of gas distribution pipes are evenly provided with pores; the top ends of gas distribution pipes are sealed; the bottom ends of gas distribution pipes are communicated with an air conveying pipe, the other end of the air conveying pipe is connected to a blower fan, and the air distribution pipes are connected to an elevating mechanism. The gas distribution device has the advantages that the gas distribution and elevation time is short, the operation and the installation are convenient, the device can be conveniently disassembled after composting, flat ground can be recovered, the space is saved, the cost for installing, cleaning and maintaining a gas supply system is reduced, the air flow is smooth and uniform, and the composting fermentation efficiency is high therefore.

Description

technical field [0001] The invention belongs to the field of aerobic composting fermentation, and in particular relates to a convenient air distribution device and a use method in aerobic composting. Background technique [0002] At present, in the process of aerobic composting of organic solid waste, aeration is a necessary condition in the process, which directly affects the growth activities of microorganisms in the compost. When the oxygen supply is insufficient, anaerobic reaction occurs in the pile to produce reducing substances, and the stench pollutes the surrounding environment and has a toxic effect on plant growth. When the turning frequency is too high or the amount of forced ventilation is too large, the compost material loses too much water and will cause drying, which will weaken or even stop the growth of microorganisms. Therefore, the problems of turning over and ventilation must be solved when the material is fermented. [0003] In the process of composti...
