Reactor composting device for aerobic fermentation

Abstract

The invention discloses a reactor composting device for aerobic fermentation, which comprises a fermentation system and a collected gas treatment system. The fermentation system consists of a fermentation tank and a gas collection tank, the bottom of the fermentation tank is provided with a backing layer and a stainless steel screen, gas guide pipes are uniformly distributed in the middle of the fermentation tank, and the bottom ends of the gas guide pipes pass through the backing layer and are fixed on the stainless steel screen. The collected gas treatment system consists of a gas collection tank and a gas treatment system. The gas collection tank is positioned below the fermentation tank and is tightly connected with the fermentation tank, and the gas treatment system consists of an extraction pump and an ammonia absorbing tank. The device of the invention has a simple structure, can effectively keep the temperature of a composted body when used for aerobic composting, is affected little by outside low temperature during composting, can implement annual production, is favorable for collecting the odor emitted in the composting process, and effectively collects and utilizes the ammonia produced in the composting process.

Description

technical field [0001] The invention relates to a reactor composting device for aerobic fermentation, in particular to an aerobic composting fermentation reactor for solving ammonia loss and heat preservation in composting. Background technique [0002] The composting process must go through a high-temperature treatment stage. However, due to external influences, especially in winter, it is difficult to maintain the high temperature of the heap. Effective measures must be taken to maintain the temperature of the heap and implement the composting of materials. In addition, ammonia gas is the main component of stench. By controlling the volatilization of ammonia gas, the generation of stench can be reduced and the nitrogen content in compost products can be kept high. At present, there are mainly two types of nitrogen loss control methods in the composting process at home and abroad: 1) Change process conditions: such as maintaining moderate temperature and ventilation rate du...
