Abstract

The invention discloses an aerating, collecting and exhausting combining system in solid-state-composting aerobic fermentation. The aerating, collecting and exhausting combining system comprises a fermentation trough, a medium-pressure draught fan set, a composting heap turner, main aeration ditches, fishbone-type branch aeration ditches, aeration ventilating pipes, aeration plates, a membrane sealing structure and an independent exhausting structure; the invention provides an application of the aerating, collecting and exhausting combining system. The combining system and the application thereof have the advantages that the medium-pressure draught fan set can be momentarily adjusted according to the oxygen requirement in the biological aerobic fermentation stage, the best suitable oxygen requirement is provided, the multiple kinds of air amount can be further provided without changed air pressure, broken openings and the dispersion state are reduced, the stability can be kept for a long time, and the cost, the maintenance cost and the requirement electric quantity are lower; the cost of a gas collecting system can be reduced through the membrane sealing fermentation trough, the stench concentration is further increased, the air sucking amount is decreased, and the defects that due to a single-trough or multiple-trough gas collecting cover and the gas collecting mode of a whole workshop, the air sucking amount is large, the air sucking difficulty is high, the motor power is large, and stench is spread in the whole workshop are overcome.

Description

[0001] technical field

[0002] The invention relates to the technical field of fermentation process control, in particular to a combined system of aeration, collection and exhaust in aerobic fermentation of solid compost and its application. Background technique

[0003] Sludge, conditioner, and back-mixed materials are mixed and stirred by the mixer and then enter the fermentation tank for fermentation. During the fermentation process, the temperature of the fermentation heap is not easy to be too high. If the temperature is too high, it will affect the death of a large number of beneficial bacteria in the material and affect the fermentation effect. , and it is necessary to provide sufficient oxygen to the microorganisms in the heap to make them fully ferment. Usually, a Roots blower is used to provide oxygen to microorganisms, and at the same time, a Roots blower or a single medium-pressure blower is used to reduce the temperature of the fermentation pile. However, the ...
