Air pulse air-permeability improvement biomass fermentation apparatus and method

Abstract

The invention discloses an air pulse air-permeability improvement biomass fermentation apparatus and method. The apparatus comprises one or more sets of pulsating air supply systems and methane supplysystems and an automatic control system, the pulsating air supply systems communicate with the methane supply systems, are located at the bottom of an overlying pile body, and perform air jet on theoverlying pile body through air jet holes, air jet areas with an angle alpha is formed, the automatic control system is connected with the pulsating air supply systems and the methane supply systems respectively, the automatic control system is used for actively identifying air-permeability of a biomass fermentation pile body and executing operations such as pulsating aeration, jet flow air-permeability improvement and safety management, the pulsating air supply systems can generate high-pressure air pulsating jet flow under the control of the automatic control system to supply oxygen to the fermentation pile body, the pulsating air supply systems and the methane supply systems can be matched to generate explosion jet flow under the control of the automatic control system, perforating andpile loosening of the pile body are realized, and the pile body air-permeability is improved. The biomass fermentation management cost is effectively reduced. The oxygen supplying and air-permeabilityimprovement effects are improved, and the effective distribution of resources is realized.

Description

technical field [0001] The invention relates to a gas pulse anti-reflection biomass fermentation device and method, which is suitable for the aerobic fermentation of grooved and stacked organic matter, especially for the biotransformation of coal and oil shale, and the organic fermentation of agricultural products and agricultural and animal husbandry waste. Oxygen fermentation, aerobic bacteria cultivation, microbial fertilizer production, etc. Background technique [0002] Aerobic fermentation is currently the main technology to realize the resource utilization of agricultural and animal husbandry waste. The current biomass aerobic fermentation technology, no matter the groove type or the stacking type, requires a compost turner to loosen the heap so as to facilitate the dispersion of oxygen in the fermentation heap and ensure the oxygen content of the fermentation heap and the activity of the bacteria. There are the following technical problems in the loosening operation...

AI Technical Summary

Problems solved by technology

There are the following technical problems in the loosening operation using turning equipment: (1) The conventional turning machine performs anti-reflection on the pile body while simultaneously completing the movement and mixing of the pile body. If it is only required to complete loosening and anti-reflection, the current The spatial distribution of the material does not change the position of the pile body, which cannot be realized by the current stacking equipment; (2) The stacking anti-reflection operation requires necessary manual management and control, and the power consumption of the stacking equipment is high, which leads to the relative production cost. (3) It is impossible to realize partial in-situ pine pile operation; (4) Whether the overlying pile needs to perform oxygenation operation, the fermentation system lacks the ability to actively judge

[0003] These technical difficulties lead to the high cost of biomass fermentation. An automatic, safe and reliable technology is needed that has loosening of the pile and automation of oxygen supply, in-situ and original structure to improve the air permeability of the pile, and management of the air permeability of the pile. to meet production needs
